The invention discloses an environment-friendly steel pickling bath acid mist inhibitor which is prepared from the following raw materials in percentage by weight: 20-30% of glycerol monostearate, 20-30% of crop straw solid extract, 5-10% of glycerol, 2-4% of 4-sulfo-orthophthalic acid, 1-2% of heptadecylhydroxyethylcarboxymethyl imidazoline and the balance of water. Compared with the prior art, the inhibitor is especially suitable for a volatile acid pickling process, can obviously inhibit acid mist, and has corrosion resistance. The inhibitor has more obvious effect especially in a hydrochloric acid pickling process when the air humidity or acid concentration is high.

The invention discloses a denitration catalyst regeneration solution and a preparation method thereof as well as a catalyst regeneration method. The denitration catalyst regeneration solution comprises the following raw material ingredients in parts by weight: 4-6 parts of vanadyl oxalate, 0.08-0.10 part of cerium nitrate, 0.11-0.13 part of lanthanum nitrate, 0.05-0.07 part of copper nitrate, 0.4-0.6 part of silica sol ST-O and 95 parts of deionized water. The catalyst regeneration method comprises the following steps of firstly, evenly mixing vanadyl oxalate and the deionized water; then, feeding cerium nitrate, lanthanum nitrate and copper nitrate into mixed solution, and fully stirring until the mixture is completely dissolved; finally, feeding silica sol ST-O, and continuing to stir until homogeneous phase is obtained; and sequentially carrying out strong scavenging and ultrasonic cleaning on an inactivated denitration catalyst module, soaking the module in cleaning solution for 18-25 minutes, continuing soaking the module in the regeneration solution for 25-40 minutes, taking out the denitration catalyst module and drying. After the denitration catalyst regeneration solution and the catalyst regeneration method are adopted, the activity of the inactivated denitration catalyst can be efficiently recovered, and the temperature range of the catalyst activity is widened.

The invention pertains to a method of passivating direct process solids (1) and to passivated and quenched compositions resulting from said method. The method of passivating direct process solids (1) according to the invention comprises combining direct process solids (1) with a passivating composition comprising clay (2), base (3), and water (4). The passivated composition of the invention comprises direct process solids (1) and a passivating composition comprising clay (2), base (3), and water (4). The quenched composition of the invention comprises the passivated composition, wherein the passivated composition has been held for a sufficient period of time for the reactive species from the direct process solids to be substantially quenched and / or oxidized.

The invention discloses a fabric softener, which comprises the following components in parts by mass: 3-15 parts of ester quaternary ammonium salt, 1-5 parts of water-soluble polyether silicone oil, 2-10 parts of amino silicone oil, and 0.2-0.8 parts of EDC , 0.06-0.18 parts of N-hydroxysulfosuccinimide, 70-80 parts of deionized water. The fabric softener of the present invention can effectively reduce discoloration when taking advantage of the good softness and slipperiness of amino silicone oil with high ammonia value, has no damage to the fabric after use, can increase the softness and air permeability of the fabric, and can be used after washing. , the fabric has good rewetability, antistatic, no yellowing, elegant and leisurely fragrance, long-lasting fragrance.

The invention discloses a low temperature antifreeze fabric softener. The low-temperature antifreeze fabric softener comprises the following components in parts by mass: 3 to 15 parts of ester quaternary ammonium salt, 1 to 5 parts of water-soluble polyether silicone oil, 2 to 10 parts of amino silicone oil, 0 .2 to 0.8 parts of EDC, 0.02 to 0.1 parts of NHS, 2 to 5 parts of an antifreeze, and 75to 85 parts of deionized water. The fabric softener of the invention can effectively reduce the color change when the amino silicone oil with a high ammonia value has the advantages of good flexibility and slipperiness, after use, the fabric softener has no damage to the fabric, can increase the softness and breathability of the fabric, after washing, the fabric has good rewetting property, antistatic performance, no yellowing, light fragrance, and long fragrance stay, and maintains good fluidity under cold climate environment of -25 DEG C.

The invention relates to a silk afterfinishing compound softening agent and a preparation method. The softening agent is nontoxic, nonirritating, very low in yellowing possibility, good in re-wettability, biodegradable, and completely harmless to an environment. The method comprises the steps that required water temperature is selected between 0 DEG C and 100 DEG C according to used different quaternization raw materials; 1-30% of ester quaternary ammonium salt is added to water, and stirred; and then 1-30% of hydrophilic amino silicone oil is added and stirred uniformly after ester quaternary ammonium salt is completely dissolved or dispersed in the water and forms a uniform white viscous emulsion. The softening agent has the advantages that 1, the softening agent adopts raw animal or plant synthetic chemicals as main components of the softening agent, and is completely nontoxic, nonirritating, very low in yellowing possibility, and good in re-wettability, and 2, the softening agent is biodegradable and completely harmless to the environment, and is an ideal silk fabric afterfinishing softening agent.

The invention discloses a one bath process desizing and dyeing technology of viscose leather base cloth. The desizing and dyeing processes of the viscose leather base cloth are finished in the same water bath. If the viscose leather base cloth is a light-color variety dyed by reactive dye, when in desizing and dyeing, the technology comprises the following steps: adding a composite desizing enzyme accounting for 1.5-3.5% of the viscose grey cloth in the weight and an anionic surfactant accounting for 0.5-2% of the viscose grey cloth in the weight into a water bath; adding an intermediate-temperature reactive dye; starting dyeing at 60 DEG C and keeping the temperature for 3-6 times; and adding sodium carbonate for color fixing in the final 2-3 times. If the viscose leather base cloth belongs to a black deep-color variety dyed by sulfur dye, when in desizing and dyeing, the technology comprises the following steps: adding a functional pretreatment agent accounting for 1-4% of the viscose grey cloth in the weight and 0.5-2% of an anionic surfactant accounting for 0.5-2% of the viscose grey cloth in the weight into a water bath; adding a sulfur dye; starting dyeing for 2-4 times at 75 DEG C; and heating to 98 DEG C and keeping the temperature for 3-6 times. The technology disclosed by the invention realizes one bath process of desizing and dyeing of the viscose leather base cloth, reduces the production time of the viscose leather base cloth, improves the production efficiency and remarkably reduces the total production cost.
