Mechanism of flame retardant? Flame retardants exert their flame retardant effects through several mechanisms, such as endothermic effect, covering effect, inhibition of chain reaction, asphyxia of non-combustible gas, etc.Most flame retardants achieve the purpose of flame retardant through the com... read more
Introduction Flame retardant, functional additives that give flammable polymers flammability, mainly designed for the flame retardant of polymer materials;There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to their u... read more
General performance Nitrile rubber has good heat resistance. Its heat resistance is better than that of natural rubber, butadiene rubber and styrene butadiene rubber. Its long-term use temperature can reach 100oC, and 120oC can be used for 40 days. ① Ozone resistance is worse than Cr, better than N... read more
Polymer cement concrete is a composite concrete composed of synthetic polymers in the binder material. Polymer concrete has higher performance, lower energy requirements and lower labor costs. Also called Latex Modified Concrete (LMC). In order to effectively seal the ring, the cement sto... read more
Cementing is to inject cement slurry between the casing ring and the formation, and the cement slurry is cured to form a cement sheath. The main function of the cement sheath is to suspend and protect the casing, reduce and delay the influence of the formation on the casing, improve the stress state... read more
