PTF ke eng (polytetrafluoethylene)?

PTF POLTETTRAFLuOEEREREREREREE ke sets'oants'o se phahameng sa machaba se nang le limela tse ngata tse nang le liathomo tsa mabenkele le liathomo tsa folline. Bololi ba folli ke sehlopha sa polasetiki ka lipehelo le melemo. PTF ke e 'ngoe ea folete e joalo ea foreitseng ea eo e fumanoang ka ho sa feleng e fetolela sehlopha sa fluopolymer mme o ile a lekanya tsela ea lits'ebetso tse fapaneng.

E 'ngoe ea likopo tse tloaelehileng tsa lisebelisoa tsa PTFF li kenyelletsa makhapetla a se nang likhohlong bakeng sa cookie ea kichineng. Ka lebaka la ho se arabele le matla a kamano ea Carbon - hangata e sebelisetsoa ho etsa liphaephe le lik'hemik'hale tse sebetsang le tse takiloeng.

PTF e entsoe joang?

PTF e etsoa joalo ka polymer efe kapa efe. E entsoe ke Theknoloji ea mahala ea polymerization e sebelisang tjo ho kenyeletsa polymerization ka mokhoa oa ho akheha naheng ea limela.

Sebopeho sa lik'hemik'hale sa PTFE se tšoana le Polyethylene; Phapang e kholo ke hore liathomo tsa hydrogen li nkeloa sebaka ke folline. Leha ho le joalo, pe le PTF li lokiselitsoe ka litsela tse fapaneng haholo.

Boholo bo boholo ba liathomo tsa Flurine li etsa junifomo, Sheath e tsoelang pele ho pota ka khabone ea khabone, ho fana ka molek'hule e ntle ea lik'hemik'hale, botle le botsitso.

Litšobotsi le ts'ebetso ea ptfe

PTFE comes in three main forms-granules, water-based dispersions, and fine powders.

Lisebelisoa tsa PTF tsa granular li hlahisoa ke ho emisoa ka mokhoa o potlakileng haholo ka sengoang a neng a akheha a sebelisa tse nyane kapa tse nyarosang. Thepa ea granulal ptfe e sebelisoa haholo ka tlhaphiso, ho hatella khatello ea maikutlo le ho putlama ha likepe.

Ho se ha ha li ha haoa metsi ho sebelisa mokhoa o tšoanang o tšosang ka metsi ka ho nyahama le ho nyahama le ho fetelletseng. Ha e le liphorollo tse thehiloeng metsing li sebelisoa haholo ka ho ba le likotsi tsa ho beha liboka le mekhoa ea ho lahla baesekele.

PTFE e khabane e pholileng ke karoloana e nyane e tšoeu e hlahisoang ke emulsion e kentsoeng emulsion e laoloang. Petfe phofo e ntle ea PTF e ka sebetsoa ho pherekano ka ho qeta nako le ho ntlafatsa.
