The mechanism of phenolic board testing standards
the article takeaway:
mechanism of phenolic plate is the important basis to measure the quality testing standards, and whether you will teach say their products much cheaper quality better, mechanism of phenolic board before testing standards have to betray oneself. Of course, these laboratory test on the basis of not all need to reach, we know the mechanism of phenolic board still benefit comparison testing standards.
mechanism of phenolic board pictures
coefficient of thermal conductivity:
is one of the most important inspection item to insulation materials, thermal conductivity coefficient of thermal conductivity, the higher that insulation performance is poorer, the lower the coefficient of thermal conductivity shows that the better the insulation performance. The mechanism of phenolic plate thermal conductivity testing standard of 0. 034w/( m。 k) , slightly lower than real gold plate thermal conductivity coefficient of 0. 039w/( m。 k) With polystyrene thermal conductivity coefficient of 0. 033w/( m。 k) Flat, insulation performance is almost beyond all inorganic insulation materials including common rock wool insulation board, homogenization of insulation board, siliceous polystyrene insulation board, foam cement and so on.
flame retardant performance:
flame retardant performance is very important to people's life safety and fire coming insulation materials do not produce combustion of protecting the buildings also has provided the safeguard for residents safe, mechanism of phenolic board testing standard for the B1 level, inspection items including combustion rate & le; 250, horizontal flame combustion of edge, 600 s total heat quantity/MJ≤ 15, the flame height of 60 seconds/mm≤ 150, without dripping, oxygen index % & ge; 30%.
other inspection standards:
other mechanisms phenolic plate inspection standard eye view we can see that, in turn, such as inspection diagonal just put two pieces of phenolic board a stack up, you will know whether was right in the rectangle, touch mechanism each part of the phenolic board knew density uniform, aspect work know if jerry is measured with a ruler, and so on, directly with torch burning mechanism of phenolic board more intuitive than in the lab data, away from fire does not produce the flame, not shrink. No drop even if qualified.
the above is to introduce the standard related content of the mechanism of phenolic plate test, hope to help you, if you need this product, single ( Aluminum foil) Caigang phenolic plate please select city bo hui, my factory production equipment advanced, timely service, wholesale prices low, sample free of charge!
