Phenolic insulation board of conventional detection
the article takeaway:
modified phenolic insulation board of routine tests including what has been bothering you. Actually, we from the inspection report, you can see it clear what inspection items. Below, please look at the modified phenolic resin with bo hui insulation insulation board what are the regular testing, hope will be helpful to you.
modified phenolic insulation board picture
fire inspection items:
modified phenolic inspection regular testing for the thermal conductivity of insulating board and fire rating, and other such as density, compressive strength, size error, bibulous rate, fracture rate, tensile strength, bending, etc. , we focus on two aspects fire rating and insulation performance. It bare board fire rating for the B1 level, fire rating basically see oxygen index, phenolic foam oxygen index greater than or equal to 38, smoke density rank less than 10 '60 s flame height less than 150 mm. Laboratory data looked a little boring, we explain with facts. It under the red high temperature flame of produce, carbide remove flame didn't light the fire continues to exist, insulation board no deformation, no drop formation, no cracking phenomenon.
modified phenolic insulation board of conventional detection is one of the main projects insulation performance test. Insulation performance measure is the coefficient of thermal conductivity. The lower coefficient of thermal conductivity value on behalf of the flame retardant heat conduction ability stronger, the stronger the insulation performance. Phenolic insulation board coefficient of thermal conductivity of 0. 034w/( m。 k) , said no thermal conductivity contrast alone is difficult to produce direct effect, its coefficient of thermal conductivity coefficient of thermal conductivity with our common polyphony board 0. 033w/( m。 k) Quite beyond the real gold insulation board heat conduction coefficient of 0. 039w/( m。 k) 。 We are familiar with eps board should, especially all kinds of polystyrene foam insulation box. Insulating small bowl of instant noodles noodles stays everyone not unfamiliar, it serves to show phenolic insulation board insulation performance is very good.
the above is to introduce the modified phenolic insulation board about conventional detection related content, 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!
