HPL board stainless steel Fireproof board ABS plastic
Picture image.png image.png image.png image.png
ingredient HPL   board is made of decorative paper impregnated with melamine resin, plus   multi-layer black or brown kraft impregnated phenolic resin laminated, and   then through the high-temperature steel (150 ) high pressure (1430psi) environment from the suppression. In   the atmosphere and acid, alkali, salt and other corrosive medium showed   passive, corrosion-resistant and not rusty high chromium (usually 12% to 30%)   alloy steel. Fireproof   board is the base paper (titanium paper, kraft paper) after melamine and   phenolic resin impregnation process, high temperature and pressure into the   core with E1-level plywood. ABS   resin backbone graft copolymer; or a rubber elastomer and a hard ABS resin   mixture.
High temperature performance HPL   board with excellent high temperature performance and fire resistance, will   not melt, drip or explosion, the European agencies to be classified in the   highest organic material fire rating, and will not release toxic and   corrosive gases Depending   on the type of stainless steel. 304# stainless steel, resistant to 1000-1200   degrees high temperature Veneer   temperature (1800C, 20 minutes) No bubble cracking, a slight change in color   No bubble cracking, a slight change in color. Lightning fire time up to 35-40   seconds, in this range, the open flame will only produce a black fume can be   wiped away, there is no chemical reaction. Like ordinary wood core, easy to   catch fire ABS   plastic thermal deformation temperature of 93 ~ 118 , the product after annealing treatment can also increase about   10 . ABS at -40 can still show some toughness, can   be used in the temperature range of -40 ~ 100
Chemical stability Because   the resin structure contains ether bonds in the epoxy part, it is stable in   many chemical environments Resistant   to water and acid in the air, but not alkali corrosion, will produce rust,   stainless steel variety, so different types of chemical stability is slightly   different Veneer   Because the resin structure contains epoxy resin part of the ether bond, so   that in many chemical environment is very stable, the core does not have   chemical stability Plastic   ABS has excellent mechanical properties, its impact strength is excellent,   can be used at very low temperatures; plastic ABS wear resistance, good   dimensional stability, but also has oil resistance, can be used under medium   load and low speed Bearing. ABS creep resistance than PSF and PC, but smaller   than the PA and POM
Cleaning ability HPL   board can remain stable for a long time, its own self-cleaning, dense   material will not adhere to dust, cleaning simple, alcohol disinfectant wipe Stainless   steel depends on whether the rusty rust or no rust, rust, then use   professional rust remover, if no rust just lost gloss, you need to use   porcelain clean spray dry Surface   smooth and clean, easy to maintain clean, small pores is not easy to be   contaminated, seams difficult to clean Plastic   ABS is not affected by water, inorganic salts, alkali and a variety of acids,   but soluble in ketones, aldehydes and chlorinated hydrocarbons, by glacial   acetic acid, vegetable oil and other erosion will have stress cracking. ABS   weathering is poor, easy to produce degradation under the action of   ultraviolet light; half an year later, the impact strength decreased by half
Moisture resistance excellent good poor Poor   (will be oxidative, yellowing, brittle).
Environmental performance E1   level, does not release harmful substances, non-flammable, non-conductive,   does not produce toxic gases when heated, will not infringe on the safety and   health of the operator Steel   did not distinguish between environmental standards, can not be clearly level There   is no radioactive, no hazardous substances spill. Insulation, arc resistance   is good and not easy to aging. Soot burning larger Most   are environmentally friendly products, the human body and the environment   will not have an impact, but the combustion will produce toxic substances
