hlahisa laminates eng?

The laminate ke lintho tse bonahalang le likarolo tse ngata e thehiloeng - le binder polymeric. E le hore re matlafatse tshebetso botlaaseng le boetse le sebelisoa ka le dikarolo teng eketsa filler. Ka mantsoe a mang, ho laminates - ha e kopana le metsoako e 'meli e ka sehloohong emeloang binder le filler. Ka motsoako pele sebediswa lehoakhoa maiketsetso. E ka etsoa ka poliester, epoxy, phenol-formaldehyde le lintho tse ling. Ho boetse ho tloaelehile hore batho ba tšebeliso ea polymers, har'a tse - silicone le thepa fluoropolymer. Ha e le go tlatsa, ka nako eo mosebetsi oa ka etsa thepa ea setso e tala e le asbestos le pampiri selulose likhoele.

Ka phetolelo ea khale ea laminate ke lakane lintho tse bonahalang tse e behoa ka mofuta oa tloaelehileng diphanele shebileng ka. lesela ka tlase ho tloaelehile hore batho mefuta e sa tsoaneng. Lakane bokima ka Range ho tloha limilimithara 0,4 ho 50, ho itšetlehile ka tse fapa-fapaneng le kobo e sebopeho. Hape, mefuta e fapaneng ya boholo bo ka bolelele le bophara. Standard fiberglass phanele a, ho etsa mohlala, e na le entsprechen karolelano 1200x1000 limilimithara. litsobotsi life tse sebetsa ena laminates, a bolela hore matla a ho mamella maemo a fapa-fapaneng mocheso. Hape, ka karolelano phasejeng bakeng sa tloaelehileng polasetiki mekoloko tse joalo tse tsoang -60 ° C ho 120 ° C. Sehlooho ho kenyelletsoa ha lintlha tsa modifiers eketsehileng, mefuta e fapaneng hona ka atolosoa.
