Description

Technical Field

[0001] This invention relates to the field of air cooling technology, and in particular to a method for processing fireproof wet curtains. Background Technology

[0002] Evaporative cooling pads, also known as water curtains, are widely used for cooling and humidifying applications, while also providing air filtration. Using evaporative cooling pads offers advantages such as energy savings, high airflow, rapid air renewal, and being environmentally friendly and pollution-free. Currently, evaporative cooling pads on the market are primarily made of paper, plastic, or metal. Paper-based evaporative cooling pads have mature technology, low cost, and high evaporation efficiency; however, prolonged use in high-temperature, high-humidity, and harsh environments can lead to mold growth and foul odors. Furthermore, dried paper evaporative cooling pads pose a flammable safety hazard when exposed to open flames, limiting their application. Plastic and metal-based evaporative cooling pads have low evaporation efficiency and are mainly used for air filtration; they are unsuitable for many applications. Some special locations require fire-resistant evaporative cooling pads, such as data centers and power plants. While different manufacturers use different raw materials and employ varying technologies and processes, all of these applications place high demands on technology and manufacturing processes.

[0003] Currently, evaporative cooling pads on the market are mainly made of paper, plastic, and metal. Plastic and metal-based evaporative cooling pads have low evaporation efficiency and are primarily used for air filtration, making them unsuitable for many applications. Paper-based evaporative cooling pads have mature technology, low cost, and relatively high evaporation efficiency; however, existing evaporative cooling pads made of ordinary paper experience reduced water absorption over prolonged use, and the paper itself poses a fire risk in high-temperature environments. Existing high-temperature resistant paper with fire-retardant properties has high flexibility and elasticity, making it difficult to process and form the corrugated shape required for evaporative cooling pads, thus limiting its application.

[0017] The processing method of the fireproof wet curtain comprises the following steps: hot-pressing high-temperature-resistant paper into a corrugated board prototype, wherein the hot-pressing temperature ranges from 80 DEG C to 450 DEG C; and the corrugated board prototype is loaded on a preset corrugated mold for heat preservation or the corrugated board prototype is heat preserved to improve the plasticity of the corrugated board prototype, wherein the heat preservation temperature ranges from 150 DEG C to 450 DEG C, and the heat preservation time ranges from 1 min to 480 min. Under the condition of high-temperature heat preservation, the shape of the corrugated board prototype is fixed, the high-temperature-resistant paper is prevented from being deformed to the initial state due to the rebound effect, the structural stability of the corrugated board monomer is ensured, and the fireproof wet curtain made of the high-temperature-resistant paper has good structural stability.

[0018] From the above description, the beneficial effects of the present application are that by pressing the corrugated paper in an environment with a temperature range of 80-450 DEG C, the shaping ability of the corrugated board blank is improved by loading the corrugated board blank on the preset corrugated mold for heat preservation or heat preserving the corrugated board blank, the temperature range of the heat preservation is 150-450 DEG C, and the time range of the heat preservation is 1-480 min, the shape of the corrugated board blank is fixed under the condition of high temperature preservation, the shape of the corrugated board blank is prevented from being deformed to the initial state by the rebound effect of the high-temperature-resistant paper, thereby ensuring the structural stability of the corrugated board monomer, and the fireproof wet curtain made of high-temperature-resistant paper has better structural stability.

[0019] Further, the high-temperature-resistant paper is hot-pressed into a corrugated board blank, and the hot-pressing temperature range is 80-450 DEG C, specifically:

[0020] The high-temperature-resistant paper is hot-pressed into a corrugated board blank using a corrugating machine, the hot-pressing temperature range of the corrugating machine is 80-150 DEG C, and the paper feeding speed range of the corrugating machine is 0.5-5 m / s;

[0021] The corrugated board blank is loaded on a preset corrugated mold, specifically:

[0022] The corrugated board blank is adsorbed to the lower mold in a light pressing manner, and the upper mold is covered after water spraying in the adsorption process, and the corrugated mold comprises a lower mold and an upper mold arranged above and below and cooperating with each other.

[0023] From the above description, the hot-pressing temperature range of the corrugating machine is 80-150 DEG C, the plasticity of the corrugated board blank obtained by hot-pressing is relatively low when the paper feeding speed range of the corrugating machine is 0.5-5 m / s, and the corrugated board blank is adsorbed to the lower mold in a light pressing manner, so that the corrugated board blank is sent into a high-temperature furnace for heat preservation after being pressed by the lower mold and the upper mold, which can ensure that the corrugated board blank is fixed by the corrugated mold during hot-pressing forming, further improve the shaping ability of the corrugated board blank, and ensure the structural stability of the corrugated board.

[0024] Further, the high-temperature-resistant paper is hot-pressed into a corrugated board blank, and the hot-pressing temperature range is 80-450 DEG C, specifically:

[0025] The high-temperature-resistant paper is hot-pressed into a corrugated board blank using a corrugating machine, the hot-pressing temperature range of the corrugating machine is 150-450 DEG C, and the paper feeding speed range of the corrugating machine is 0.1-10 m / s;

[0026] The corrugated board blank is heat preserved, specifically:

[0027] The corrugated board blank is sent into a high-temperature furnace for heat preservation, and the heat preservation temperature ranges from 150 DEG C to 450 DEG C, and the heat preservation time ranges from 1 min to 480 min.

[0028] As described above, the corrugated blank obtained by sending the high-temperature resistant paper into a corrugator with a hot-pressing temperature ranging from 150 DEG C to 450 DEG C and a paper feeding speed ranging from 0.1 m / s to 10 m / s can be heat preserved in a high-temperature furnace with a temperature ranging from 150 DEG C to 450 DEG C and a heat preservation time ranging from 1 min to 480 min, so that the high-temperature resistant paper can be quickly formed.

[0029] Further, the fireproof wet curtain is cut into a preset size, and a saw blade without teeth is used for cutting while polishing.

[0030] As described above, the fibers of the fireproof wet curtain made of high-temperature resistant paper are long and strong, and the cutting surface is seriously roughened by using a common saw blade for cutting, so that the cutting strength can be ensured by using a saw blade without teeth for cutting while polishing, and the cutting surface can be prevented from being roughened.

[0031] Further, the fireproof wet curtain is cut into a preset size, and a saw blade with multiple saw teeth is used for cutting, and the multiple saw teeth of the saw blade are located on the same plane.

[0032] As described above, the fibers of the fireproof wet curtain made of high-temperature resistant paper are long and strong, and the cutting surface is seriously roughened by using a common saw blade for cutting, so that the cutting strength can be ensured by using a saw blade with multiple saw teeth located on the same plane for cutting, thereby preventing the cutting surface from being roughened.

[0033] Further, the material of the high-temperature resistant paper is meta-aramid fiber, para-aramid fiber, poly-p-phenylene benzobisoxazole fiber, aromatic polyester fiber, polyphenylene sulfide fiber, pyridine aromatic heterocyclic fiber, benzimidazole fiber, polysulfone-based amide fiber, polyimide fiber, polyamide-imide fiber, polyether ether ketone fiber, polytetrafluoroethylene fiber, carbon fiber, ceramic fiber, glass fiber, basalt fiber or boron fiber.

[0034] Further, the following steps are further included before the fireproof wet curtain is prepared:

[0035] Step one: preparing an antibacterial and mildew-resistant liquid, and soaking or spraying the antibacterial and mildew-resistant liquid on the corrugated board monomer and then drying;

[0036] Step two: preparing a resin, and soaking or spraying the resin on the corrugated board monomer prepared in step one and then drying;

[0037] Step three: high-temperature curing the corrugated board monomer prepared in step two.

[0038] As can be seen from the above description, the corrugated board monomer has the antibacterial and mildew-proof effect by attaching the components of the antibacterial and mildew-proof liquid to the corrugated board monomer. The corrugated board monomer prepared by impregnating the corrugated board monomer with resin and high-temperature curing can tightly attach the components of the antibacterial and mildew-proof liquid to the corrugated board monomer, so that the antibacterial rate of the corrugated board monomer can reach 99.83%. At the same time, the corrugated board monomer is in a state that all the micro-pores are fully opened during impregnation and high-temperature curing. At this time, the corrugated board monomer has the characteristics of good water absorption and high evaporation efficiency. The corrugated board monomer prepared after resin curing can persistently keep the state of opening the pores, so that the water absorption and evaporation efficiency do not change significantly in the case of placing in the air for a long time, and the quality of the fireproof wet curtain with high antibacterial rate and high evaporation rate is ensured.

[0039] Further, the antibacterial and mildew-proof liquid is soaked or sprayed on the corrugated board monomer and then dried after spinning dry or directly dried, and the drying temperature ranges from 150°C to 300°C.

[0040] The resin is soaked or sprayed on the corrugated board monomer prepared in step one and then dried after spinning dry or directly dried, and the drying temperature ranges from 100°C to 150°C.

[0041] The temperature range of high-temperature curing in step three is 150°C-300°C, and the time range of high-temperature curing is 3S-30S.

[0042] As can be seen from the above description, the temperature range for drying the corrugated board monomer after soaking or spraying the antibacterial and mildew-proof liquid is 150°C-300°C, which can ensure that the water on the corrugated board monomer after soaking or spraying is dried, and the effective components of the antibacterial and mildew-proof liquid are retained. The temperature range for drying the corrugated board monomer after soaking or spraying the resin on the corrugated board monomer prepared in step one is 100°C-150°C, which can ensure that the water on the corrugated board monomer is dried, and the effective components of the antibacterial and mildew-proof liquid are locked on the corrugated board monomer. The temperature range of high-temperature curing is 150°C-300°C, and the time range of high-temperature curing is 3S-30S, which can ensure that the resin is fixed on the corrugated board monomer.

[0043] Further, the solubility of the resin prepared in step two ranges from 5% to 50%.

[0044] As can be seen from the above description, when the solubility of the resin ranges from 5% to 50%, the resin has good impregnation ability, so that the resin can be better attached to the surface of the corrugated board monomer.

[0045] Further, step one is specifically:

[0046] The component proportion of the antibacterial mildew-proof liquid is: 10 ppm of nano-silver, 15 ppm of nano-copper, 100 ppm of nano-zinc and 1% of nano-titanium dioxide.

[0051] The temperature range of high-temperature curing in the step three is 300℃, and the time range of high-temperature curing is 3S.

[0052] From the above description, it can be known that the corrugated board monomer is soaked in the antibacterial mildew-proof liquid with certain component proportion, and is dried after centrifugal drying, so as to ensure the drying efficiency. At the same time, the phenolic modified resin with a concentration of 5% is sprayed on the corrugated board monomer, and drying and high-temperature curing can ensure that the corrugated board monomer has good antibacterial property and water absorption.

[0053] Further, the step one is specifically:

[0054] The component proportion of the antibacterial mildew-proof liquid is: 100 ppm of nano-silver, 10 ppm of nano-copper, 50 ppm of nano-zinc and 0.5% of nano-titanium dioxide;

[0055] The corrugated board monomer sprayed with the antibacterial mildew-proof liquid is dried, and the drying temperature is 100℃;

[0063] The corrugated board monomer sprayed with the antibacterial and mildew-proof liquid is dried, and the drying temperature ranges from 120℃;

[0064] The step two is specifically:

[0065] The resin is cyanamide resin, and the concentration of the cyanamide resin is 20%;

[0066] The corrugated board monomer soaked with the resin is centrifugally dried and then dried, and the drying temperature ranges from 100℃;

[0067] The temperature range of high-temperature curing in the step three is 200℃, and the time range of high-temperature curing is 5S.

[0068] From the above description, it can be known that the corrugated board monomer is sprayed with the antibacterial and mildew-proof liquid with certain component ratio and then dried, and the cyanamide resin with a concentration of 20% is soaked on the corrugated board monomer, and the centrifugal drying, drying and high-temperature curing are sequentially performed, so that the corrugated board monomer has good antibacterial property and water absorption.

[0069] Further, the step one is specifically:

[0070] The component ratio of the antibacterial and mildew-proof liquid is: 100ppm of nano-silver, 50ppm of nano-copper, 70ppm of nano-zinc and 1.5% of nano-titanium dioxide;

[0071] The corrugated board monomer soaked with the antibacterial and mildew-proof liquid is centrifugally dried and then dried, and the drying temperature ranges from 150℃;

[0075] The temperature range of high-temperature curing in the step three is 200℃, and the time range of high-temperature curing is 5S.

[0076] As can be known from the above description, after the anti-bacterial and mildew-proof liquid with certain component ratio is soaked into the corrugated board monomer, the drying and the drying are sequentially performed, meanwhile, the phenolic modified resin with the concentration of 50% is sprayed on the corrugated board monomer, and after the drying and the high-temperature curing, the corrugated board monomer can have good antibacterial property and water absorption.

[0077] Further, the fireproof wet curtain prepared by layering the plurality of corrugated board monomers is specifically:

[0078] Before the plurality of corrugated board monomers are layered, the bonding resin is sprayed on the corrugation of each corrugated board monomer;

[0079] After the plurality of corrugated board monomers are layered, the fireproof wet curtain is prepared after high-temperature curing.

[0080] As can be known from the above description, after the bonding resin is sprayed on the corrugation of each corrugated board monomer, the plurality of corrugated board monomers are layered, and the plurality of corrugated board monomers are tightly bonded by using high-temperature curing, so that the stability of the structure of the fireproof wet curtain is ensured.
