Applications of PVC pipe - Coal Seam Gas Coal seam gas production is water hungry business. Millions of gigalitres of water are brought to the surface, removed from the coal seam in order for the gas to be extracted. Conservative estimates suggest coal seam gas wells could draw 300 gigalitres of water from the ground each year from the some 40,000 coal seam gas wells estimated for Australia. Once the water is brought t…

Benefits of PVC Pipes-2 Coefficient of FrictionWhen piping systems are designed one of the main concerns is flow rate and pressure. PVC Pipes provide smoother wall surfaces that reduce fluid friction and resistance to flow. This hydraulic smoothness inhibits slime build-up in sewers and virtually eliminates tuberculation and encrustation in water distribution mains. The end results are significantly lo…

Innovations and Advances in PVC Technology-2 In the PVC market there’re some companies who developed a renewable modifier for PVC that increases the strength and resists fungi and biodegradation. PHA (polyhydroxyalkanoate), a biobased copolymer, offers improved processing with all PVC compounds. While the PHA polymer is biodegradable, when used in a non-biodegradable polymer, the biodegradation process is not increased. T…

Innovations and Advances in PVC Technology-1 PVC PipePVC pipe is approximately 75% less expensive in use than PE pipe, (polyethylene HDPE). New advancements include PVC-O, oriented PVC and PVC-M, modified PVC. PVC-O has been successfully used in Australia for almost 20 years. This pipe is produced by re-aligning the molecules in PVC with Biaxial orientation. The pipe produced is considerably stronger, allowing the wall th…

What are the reasons why flame-retardant PP is used in the socket housing Currently, some switchboard enclosures are made of PC and ABS materials, but some are gradually replacing PC and ABS materials with flame-retardant PP. why? Let us see why: 1, flame retardant PP is usually cheaper than ABS and PC materials, so many manufacturers choose flame retardant PP for cost reasons. .. 2. Flame-retardant PP is considered as a safe housing material in hous…

Production methods of brominated flame retardants and others Preparation of brominated flame retardant (39568-99-5): 2,3,5,6-tetrabromo-p-xylene was synthesized by reaction of p-xylene with Br2 catalyzed by AlCl3, and the product was replaced by a-H.1. Synthesis of tetrabromo-p-xylene: 1000kg bromine and 3kg anhydrous AlBr3 were added into the reactor in turn. Cooling with ice brine to 0-3 C, slowly adding 80 kg xylene under stirring. Whe…

Encapsulated red phosphorus (RP) flame retardant masterbatch In order to increase the flame resistance of polymer materials, they are mainly used in polymer materials such as plastics, rubber, fibers and so on. Most of these materials can be burned. Plastics, in particular, must be used in transportation, construction, electrical equipment, aviation, space flight and so on. It is urgent to solve the problem of its anti-combustion. The use…
