Physicochemical properties:
1.Colorless liquid and irritating dour.
2.Solubility water, ethanol, benzene and ethyl ether immiscible, insoluble in carbon disulphide.
Storage:
1.Keep it in cool, ventilated place
2.Keep away from heat surface, sparks, open flames and other ignition sources, no smoking. In winter, keep it above 0 ℃ to prevent freezing.
3.Keep container tightly closed.must be kept separate from the oxidant and alkali.
4.Use explosion-proof [electrical/ventilating/lighting]equipment.
5.Use non-sparking tools.
6.Ground and bond container and receiving equipmen
Application
1. Instead of glacial acetic acid,it is used in dyeing and finishing pro-cesses of acrylic. dacron, nylon and other Chemical fiber,wool. silkand other animal fiber,cotton. linen. yarn and other plant fiber,Waxprinting,and blend fabric.
2. The adjustment of PH value of all kinds of acid pickling, dyeingbath (including color bath),color fixing,resin finishing etc.
3. Producing some kinds of dyestuff,such as Benzidine Yellow G.
Advantage
The function and effect are better than the other dyeing acid andglacial acetic acid.lt has no damage to the fiber,in dyeing bath pHvalue is stable.it have no acid fold,sediment and effects of hardwater,improve dye uptake and level-dyeing property of somedyestuff ,and have no effects on coloured light or color fastness ofayed products.In addition,no pungent smell, no frozen in winter, safeand easy to use.Dyeing agent is a compound acid, mainly composed of hydroxyl alkyd. Its significant advantage over acetic acid is that the acid value in the working liquid is the same. It can not only achieve a stable PH value in the working bath without adding any buffer, but also does not harm the fiber, has no effect on the color light and color fastness, and has the function of eliminating the surface frizziness of cotton fabric. To smooth the surface of the fabric.
1, used as polyester, nylon, acrylic, sheep Chemicalbook wool and other fibers dyeing PH regulator. The product has stable acidity and similar buffering capacity to glacial acetic acid.
2. Alkali neutralizer.
3. Improve the brightness and stability of dyeing color.
4. It is helpful to disperse and dissolve dyes.
5, does not affect the color light and fastness.
6, does not contain sulfuric acid root, hydrochloric acid root, does not damage the fiber.
7. No adverse effects on other processes.
8, stable acidity, strong buffer. Non-volatile, odorless.
