Hlalosa phapang lipakeng tsa epoxy glass fiber board le PTFE board ka botlalo

Kajeno, ke rata ho arolelana le uena phapang pakeng tsa epoxy glass fiber board le PTFE board, joale a re ke re e shebe hammoho.

Pele ho tsohle, re hloka ho tseba hore na epoxy glass fiber board le PTFE board ke eng.

Lipoleiti tsa PTFE li arotsoe ka mefuta e ‘meli: lipoleiti tse bōpiloeng le lipoleiti tse fetotsoeng. Lipoleiti tse bōpiloeng li entsoe ka resin ea polytetrafluoroethylene ka ho bōptjoa ka mocheso oa kamore, ebe o sintered le ho pholile. The turning board e entsoe ka PTFE resin ka ho tobetsa, ho sinta le ho ebola. Ho na le mefuta e ‘meli ea lipoleiti tsa PTFE: lipoleiti tse bōpiloeng le lipoleiti tse fetotsoeng. Lipoleiti tse bōpiloeng li entsoe ka resin ea polytetrafluoroethylene ka ho bōptjoa mocheso oa kamore, ebe o sintered le ho pholile. The turning board e entsoe ka PTFE resin ka ho tobetsa, ho sinta le ho ebola. Ho hanyetsa mocheso o phahameng ho fihlela ho 250 ℃, ho hanyetsa mocheso o tlase -196 ℃, ho hanyetsa kutu, ho hanyetsa boemo ba leholimo, ho tlotsa haholo, ho se khomarele le litšobotsi tse ling. Ntle le tšepe ea alkali e qhibilihisitsoeng, poleiti ea PTFE ha e na ho senyeha habonolo ke lik’hemik’hale leha e le life tsa lik’hemik’hale. Ka mohlala, ka sulfuric acid e ngata, nitric acid, hydrochloric acid, kapa e phehiloeng ka aqua regia, boima ba eona le ts’ebetso ea eona ha e fetohe, ‘me e batla e sa qhibilihe ka har’a li-solvents tsohle.

Epoxy glass fiber board e boetse e bitsoa epoxy glass fiber board, epoxy phenolic laminated glass cloth board, epoxy resin e bua ka motsoako oa polymer o nang le lihlopha tse peli kapa ho feta tsa epoxy molek’hule. Boima ba molek’hule ha bo phahame. Sebopeho sa limolek’hule tsa epoxy resin se khetholloa ke sehlopha se sebetsang sa epoxy ka har’a ketane ea molek’hule. Sehlopha sa epoxy se ka fumaneha qetellong, bohareng kapa ka sebopeho sa cyclic sa ketane ea molek’hule. Hobane sebopeho sa limolek’hule se na le lihlopha tse sebetsang tsa epoxy, li ka kopana le li-cross-linking reactions le mefuta e fapaneng ea pheko ho etsa li-polymers tse sa tsitsang le tse sa tsitsang tse nang le sebopeho sa marang-rang a litsela tse tharo.

Joale phapang ke efe lipakeng tsa epoxy glass fiber board le PTFE board?

Boto ea PTFE e entsoe ka resin ea polytetrafluoroethylene ka mokhoa o khethehileng o kang ho bōpa, khatello ea hydraulic, ho fetoha, joalo-joalo. Ts’ebetso ea eona e ka mamella mocheso o phahameng oa likhato tse 260. Boto ea fiber ea khalase ea epoxy e entsoe ka fiber ea khalase e kenngoeng ka sekhomaretsi sa epoxy resin le se phekolang. , Ho hanyetsa mocheso ke hoo e ka bang likhato tse 100, boto ea PTFE e ka mamella leha e le efe ea acid le alkali, ‘me epoxy e tšaba acid e matla. Ho latela pono ea likarolo tsa polasetiki, ea pele ke ea polasetiki ea thermoplastic, ‘me ea morao-rao ke ea polasetiki ea thermosetting. Boto ea fiber ea khalase ea epoxy e na le matla a phahameng mocheso oa kamore.
