Kọwaa ihe dị iche n’etiti epoxy iko eriri osisi na bọọdụ PTFE n’ụzọ zuru ezu

Taa, m ga-amasị ịkọrọ gị ihe dị iche n’etiti epoxy iko eriri osisi na PTFE osisi, mgbe ahụ, ka anyị na-a lee anya na ya ọnụ.

Mbụ niile, anyị kwesịrị ịma ihe epoxy iko eriri osisi na PTFE osisi bụ.

A na-ekewa efere PTFE ụzọ abụọ: efere a kpụrụ akpụ na efere tụgharịa. A na-eji resin polytetrafluoroethylene mee efere ndị a kpụrụ akpụ site n’ịkpụzi ya na ụlọ okpomọkụ, wee kpoo ya ma mee ka ọ dị jụụ. Emere bọọdụ ntụgharị nke PTFE resin site na ịpị, ịgbanye, na bee. E nwere ụdị efere abụọ nke PTFE: efere akpụziri na efere tụgharịa. A na-eji polytetrafluoroethylene resin mee efere ndị a kpụrụ akpụ site n’ịkpụzi na ụlọ okpomọkụ, wee kpoo ya ma mee ka ọ dị jụụ. Emere bọọdụ ntụgharị nke PTFE resin site na ịpị, ịgbanye, na bee. High okpomọkụ eguzogide ruo 250 ℃, ala okpomọkụ eguzogide -196 ℃, corrosion eguzogide, ihu igwe eguzogide, elu lubrication, na-abụghị adhesion na ndị ọzọ e ji mara. Ewezuga metal alkali a wụrụ awụ, efere PTFE anaghị emebi emebi site na reagents ọ bụla. Dịka ọmụmaatụ, n’ime sulfuric acid, nitric acid, hydrochloric acid, ma ọ bụ ọbụna sie na aqua regia, ịdị arọ ya na arụmọrụ ya adịghị agbanwe agbanwe, ọ fọrọ nke nta ka ọ ghara ịsacha ya na ihe mgbaze niile.

Epoxy iko eriri osisi na-akpọ epoxy iko eriri osisi, epoxy phenolic laminated iko ákwà osisi, epoxy resin na-ezo aka organic polymer compound nwere abụọ ma ọ bụ karịa epoxy iche iche na molekul. The ikwu molekul uka nke bụ elu. Ihe e ji mara ihe owuwu molekụla nke resin epoxy bụ otu epoxy na-arụ ọrụ na yinye molekụla. Otu epoxy nwere ike ịdị na njedebe, n’etiti ma ọ bụ na usoro cyclic nke yinye molekụla. N’ihi na ihe owuwu molekụla ahụ nwere otu epoxy nọ n’ọrụ, ha nwere ike nweta mmeghachi omume na-ejikọta ya na ụdị ọgwụgwọ dị iche iche iji mepụta polymers na-adịghị ike na enweghị ike nwere usoro netwọkụ ụzọ atọ.

Ya mere, ihe dị iche n’etiti epoxy iko eriri osisi na PTFE osisi?

Ejiri osisi PTFE nke polytetrafluoroethylene resin site na usoro pụrụ iche dị ka ịkpụzi, nrụgide hydraulic, ntụgharị, wdg. Ọrụ ya nwere ike iguzogide okpomọkụ dị elu nke ogo 260. Igwe eriri iko epoxy bụ eriri iko nke etinyere na gluu resin epoxy na onye na-agwọ ọrịa. , The okpomọkụ na-eguzogide bụ banyere 100 degrees, na PTFE osisi nwere ike iguzogide ọ bụla acid na alkali, na epoxy na-atụ egwu acid siri ike. Site n’echiche nke nhazi plastik, nke mbụ bụ nke plastik thermoplastic, nke ikpeazụ bụ nke plastik thermosetting. The epoxy iko eriri osisi nwere nnukwu ike na ụlọ okpomọkụ.
