Embodiment 4

[0019] In this embodiment, a tile line glue is proposed for use in a tile line machine, and the characteristics of the glue are as follows: Viscosity: Use a Tu-4 cup to measure viscosity. As long as the temperature is 23±2 degrees Celsius, use a stopwatch to measure the outflow time. The time in seconds is the viscosity value. The unit of measurement of the viscosity cup is seconds.

[0020] Gelatinization: generally refers to the gelatinization (α-ization) of starch, which is to mix starch in water and heat it. When it reaches a certain temperature, the starch granules swell and collapse to form a viscous, uniform, transparent paste solution.

[0021] Gelatinization temperature: The temperature at which starch begins to dissolve from starch granules and the viscosity rises rapidly.

[0022] Preparation before dispensing glue: Check the status of the glue preparation tank, glue storage tank, water tank that need to be used and whether all pipelines are unobstructed.

[0023] Obtain the required starch and other raw materials according to the process requirements and production needs.

[0024] Glue preparation operation process: Prepare enough water in the water tank in advance.

[0025] Turn on the water pump and pump an appropriate amount of water from the water storage tank into the glue preparation tank according to the process requirements.

[0026] Turn on the stirring motor of the glue preparation tank and add appropriate amount of starch or other raw materials into the glue preparation tank according to the formula requirements.

[0027] When preparing starch glue, you need to open the steam valve and heat to boil.

[0028] Add the necessary additives when appropriate according to the process requirements.

[0029] When preparing starch glue, pay attention to the thermometer. When the temperature reaches the temperature required by the glue preparation process, first close the steam valve and then close the stirring motor to keep warm (the insulation time is determined according to the process requirements and the state of the glue).

[0030] Use a measuring cup to take an appropriate amount of rubber sample to test the properties (viscosity, temperature, pH value, etc.).

[0031] Glue ratio: water-powder ratio is controlled at 2.5, and the ratio of caustic soda to water in the alkali solution formula is 1:3.5. Preferably, the ratio of caustic soda to water in the alkali solution formula is 1:4.5.

[0032] Glue two-step glue making process: The production staff or glue preparation staff adds 112 parts of tap water into the feeding barrel, opens the steam valve to heat the water temperature to 24-26℃, adds 12 parts of starch, stirs evenly, then adds 12 parts of alkali solution, stirs for 5 minutes, waits until the glue flow rate reaches 13-20 seconds, adds 235 parts of water and 125 parts of starch for the second time, adds 1.4 parts of borax, continues stirring for 5 minutes, and stirs evenly.

[0033] Glue viscosity detection method: Viscosity test: The process inspector or production staff will use the national standard No. 4 flow cup to test the flow rate of the prepared glue and record the test results. The flow rate is qualified if it reaches 13-20 seconds or more.

[0034] Gelatinization temperature detection: Take 60ml of the newly prepared glue and pour it into a 250ml beaker.

[0035] Pour 100ml of boiling water (above 80 degrees) into a 500ml stainless steel liquid receiving cup, place the small beaker containing glue in the stainless steel cup for water bath heating, and stir clockwise with a thermometer. After the glue solidifies, read the temperature (keep your eyes and the thermometer scale level), which is the gelatinization temperature of the glue. The gelatinization temperature is 60℃-65℃.

[0036] Each time the glue is re-prepared, the viscosity must be tested in time to see if it is qualified.

[0037] Shelf life: 24 hours (when producing in a single shift, the production should be limited in quantity, and the glue should be re-dispensed for each shift, and the remaining glue should be used in the first shift).

[0038] In summary, the present invention improves the bonding strength of the glue and ensures a firm connection between the cardboards by controlling the water-powder ratio and adding a specific amount of borax. The optimized formula enables the glue to maintain good adhesion and stability even in a high temperature and high humidity environment, reducing the problem of glue performance degradation caused by environmental factors. The glue provided by the present invention has a moderate viscosity and gelatinization temperature, is easy to operate and use on a corrugator, and improves production efficiency. The problems existing in the prior art are solved, and it is particularly suitable for a high temperature and high humidity production environment, which helps to improve the quality and efficiency of carton production.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
