How to make nitro how to make nitro system is made

Nitrous surface ripening method

This is a traditional fur ripening method in China. This method is convenient to take materials, the product is soft and soft, the color of the fur is whiter, and the tensile strength of the skin plate is higher. But the product water resistance and temperature resistance is poor, there is a bad smell, the production of small families, this method can still be used.

Nitrate preparation: take 10 kg of sodium sulfate (nitrate of man) dissolved in 100 kg of water and then add 25 kg of flour and mix evenly into. Nitrate dosage is about 10 times the weight of the fur.

Nitrate system: the softening of the treated fur immersed in nitrate, mixing soaked, on the pressure of the creature, so that it is immersed in the liquid below the surface, and turn once a day. Dip nitrate time depending on the air temperature. In spring and fall, the air temperature at 15 ~ 20 ℃ when generally immersed 16 ~ 22 days, summer temperatures up to 30 ℃, immersed about 15 days to start. Finished product inspection method is to fold the skin plate or hand defense strong squeeze nitrate. If the skin plate shows white color and good dehydration, it means that it has been nitrated well. Finished products from the tank do not dip in raw water, then dry and shoveling soft treatment to get to the finished product.
