Thermosetting
Cov ntaub ntawv phenolic yog thermosetting.
Phenolic yas, tseem hu ua bakelite, yog ib qho nyuaj thiab nkig thermosetting yas. Nws yog ua los ntawm phenolic resin thiab tsim rau hauv cov khoom los ntawm kev sib txuas sib txuas. Nws muaj cov yam ntxwv ntawm insoluble thiab infusible, uas yog, nws tsis tuaj yeem yaj lossis softened dua tom qab kho. Cov yam ntxwv ntawm cov yas phenolic no ua rau nws siv dav hauv cov khoom siv hluav taws xob rwb thaiv tsev, cov rooj tog zaum, cov khoom siv niaj hnub, khoom siv tes ua, thiab lwm yam. Tsis tas li ntawd, phenolic yas kuj muaj cov yam ntxwv ntawm cov neeg kho tshuab siab, toughness thiab hnav tsis kam, dimensional stability, corrosion resistance, thiab zoo heev hluav taws xob rwb thaiv tsev kev ua tau zoo. Nws yog tshwj xeeb tshaj yog tsim nyog rau kev ua insulating Cheebtsam ntawm cov khoom siv hluav taws xob thiab cov twj paj nruag, thiab tuaj yeem siv rau hauv qhov kub thiab av noo.
