H Karaehe Wera Epoxy Pepa Karaehe marama matomato Epgc308/3250 mo nga Taputapu Ngawha
Whakaahuatanga Hua
Ko tenei hua he hua whakakikoruatia i hangaia me te whakamaarama matū he kakahu karaihe karaka-kore hei taonga tautoko, ma te pehi wera me te Tg epoxy resin teitei hei here. haumākū.Ko te thermostability he kōeke F, e tika ana mo nga momo motini katoa, 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 wera nui,
te tere pupuri kaha miihini≥50% i raro i te 180 ℃;
3.Moisture resistance;
4.Heat resistance;
5. Temperature resistance:Koeke H
Taurangi Mahinga Matua
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, kia kore he mirumiru, rua me nga kita, engari ko etahi atu ngoikoretanga e kore e pa ki te whakamahinga ka whakaaetia, penei i: nga karawarawa, te nuku, te paru me etahi waahi. Ko te mata o te mutunga e kore e wetewete, e ngatata.
Taupānga
He pai mo nga momo motuka, taputapu hiko, hiko me etahi atu mara.
