Heerka dahaarka ee guddiga fiber galaas galaxy

Darajada fiberboard-ka galaaska epoxy ee ay xuseen macaamiisha guud maahan darajo farsamo, laakiin waa heerka caabbinta heerkulka sare ee alaabta dahaarka. Astaamaha dahaarka ee walxaha dahaadhku waxay si dhow ula xiriiraan heerkulka. Heerkulka sarreeya, ayaa ka sii daraya wax-qabadka dahaarka ee walxaha dahaadhka ah. Si loo hubiyo xoogga dahaarka, walxo kasta oo dahaadh ah ayaa leh heerkulka ugu sarreeya ee la oggol yahay ee ku habboon. Heerkulkan hoostiisa, waxa loo isticmaali karaa si badbaado leh muddo dheer, oo si dhakhso ah ayey u gabowmi doontaa haddii uu ka sarreeyo heerkulkan. Marka loo eego heerka caabbinta kulaylka, walxaha dahaarka ayaa loo qaybiyaa Y, A, E, B, F, H, C iyo heerar kale. Tusaale ahaan, heerkulka shaqada ee ugu badan ee la oggol yahay ee darajada A waa 105 ° C, iyo inta badan qalabka dahaadhka ah ee transformers-ka qaybinta iyo matoorada guud ahaan loo isticmaalo waa Class A, sida looxyada dahaadhka resin epoxy iyo wixii la mid ah.
