3248 Epoxy Glassfiber Rau Raina
Whakaahuatanga Hua
Ko tenei hua he hua whakakikorua i hangaia me te whakamaarama matū he kakahu karaihe karaka-kore hei taonga tautoko, ma te pehi wera me te kapia epoxy hei binder.He kaha te kaha miihini i raro i te pāmahana teitei, me te pai o te hiko i raro i te haumākū nui.Ko te thermostability he tohu F, e tika ana mo nga momo motuka, taputapu hiko, hiko me etahi atu mara.
Ngā āhuatanga
1.He pai te pumau hiko i raro i te haumākū nui;
2.High kaha miihini i raro i te teitei
te pāmahana, te kaha miihini
tere pupuri≥50% i raro i te 155 ℃;
3.Moisture resistance;
4.Heat resistance;
5. Temperature resistance:Koeke F
Tautukunga ki nga Paerewa
I runga ano i te GB/T 1303.4-2009 nga raima whakamaarama hiko hiko mo nga laminate pakeke - Wāhanga 4: nga raima epoxy resin pakeke.
Te ahua: kia papatahi te mata, kaore he mirumiru, he rua me nga kita, engari ko etahi atu ngoikoretanga e kore e pa ki te whakamahinga ka whakaaetia, penei: nga karawarawa, te nuku, te stains me etahi waahi.
Taupānga
He pai mo nga momo motuka, taputapu hiko, hiko me etahi atu mara.
