3,Use
(1) As a new type of sewage, industrial wastewater, oilfield fungicide, can replace the traditional toxic and harmful residual fungicide.
(2) As a papermaking plastic flame retardant and hybridity agent.
(3) It is the main raw material for the synthesis of THPC-Urea, which is used for pure cotton flame retardant.
4,The production process
Add HCl and HCHO to the reactor (1), open the gas-liquid circulation mixing reaction pump (2), add PH3 to the gas-liquid circulation mixing reaction pump (2), and absorb PH3 through the gas-liquid circulation mixing reaction device at 50-60℃, and the PH3 that is not fully absorbed enters the next gas-liquid circulation mixing reaction pump. The reaction end point was determined by testing the content of HCHO through the central control. After the reaction was finished,Tetrakis Hydroxymethyl Phosphonium Chloride was concentrated under reduced pressure.
5,Preventive measures
Avoid inhaling dust/smoke/gas/smoke/vapor/spray.
Wash your skin thoroughly after work.
Do not eat, drink or smoke while using this product.
Avoid release into the environment.
Wear protective gloves/protective eye patches/protective masks.
In situations where ventilation is inadequate, wear respiratory protection.
6,Pack
250kg polythene plastic drum or 1000kg IBC drum
7,Storage
Store in a cool, ventilated warehouse and keep tightly sealed. Should be stored separately from oxides, edible chemicals.
Tetrakis Hydroxymethyl Phosphonium Chloride(THPC) belongs to the eighth class of dangerous chemicals, export to foreign countries need to go through legal inspection procedures. It has certain anti-corrosion, disinfection, sterilization and flame retardant effect. Due to the chlorine element, after combining with urea can produce phosphorus halogen nitrogen three synergistic flame retardant.
