1, ptfe hlooho phala molomo tlhahiso
PTFE phala tjheseletsa ka ho tiisa hlooho ho ea pele ho tsohle, re lokela ho etsa PTFE tiiso hlooho nozzle, ho ea ka boholo ba nozzle bophara tšepe hlooho le ho ea ka karolo e itseng ka ho sebelisa phofo tshebetso ho etsa nozzle ho etsa nozzle, 8 lihora tse sintered tlas'a 380 plus kapa ho tlosa likhato tse 5 tsa Celsius, ka mor'a ho phethoa ha nozzle e ntle ea sintering e nang le lathe koloi ho ea boholo bo nepahetseng, ho thoholetsa PTFE tube ka nako ena eo ue qetileng.
2, ho bula hlooho ea ptfe

3, ptfe phala molomo tjheseletsa
Ka mehato e 'meli ea pele, re ka etsa welding ea PTFE.Mona rea tseba hore ho na le mekhoa e 'meli ea ho tjheseletsa (ho tjheseletsa kgatello e chesang le ho tjheseletsa moya o chesang).Re tla li hlalosa ka bonngoe.
(1) ho cheselletsa khatello e chesang
Pele ho chesa khatello ea mocheso re lokela ho tseba tsebo e hlokahalang ea theoretical, ho chesa khatello ea mocheso ke mofuta oa tjheseletsa e chesang, ho fana ka mocheso o lekaneng le khatello e lekaneng ea khatello. Mona, re lokela ho etsa bonnete ba hore mocheso oa mocheso oa tjheseletsa o lokela ho fihla ho 673.15k le khatello e fihla ho 1-2mpa. .Ka hona, e le ho etsa bonnete ba hore tjheseletsa, re lokela ho etsa liforomo tse tsamaellanang ho etsa bonnete ba ho phethoa ka katleho ha khatello ea mocheso ea mocheso.
(2) ho cheselletsa moea o chesang
Ka mokhoa o ts'oanang, ho cheselletsa moea o chesang oa ptfe ke mofuta oa tjheseletsa e chesang, e bonolo haholo ho feta khatello e chesang mme ha e hloke liforomo tse ngata.Kamora ho beha molomo oa phala, lere la tjheseletsa la PFA le sethunya sa ho cheselletsa moea o chesang ho feta 713K li sebelisetsoa ho futhumatsa PFA pele ebe e e beha holim'a seam ea welding bakeng sa welding e tsoelang pele.
Tlhokomeliso: hore na ho chesa khatello ea tjheseletsa kapa mocheso o chesang moea tjheseletsa mocheso e tla ba phahameng ho feta melting ntlha ya ptfe, ptfe ka khoneha tlas'a mocheso cracking, e hlahisa ka tshebetso ya pyrolysis perfluorinated isobutylene le likhase tse ling tse chefo, kahoo tjheseletsa e lokela ho ba ka. tikoloho ea moea, ha boemo bo sa lumelle joalo ka tjheseletsa ea tanka e nang le fluorine leneng tlhahisong e tlameha ho sebelisa netefatso ea phallo ea moea ea fan le ho roala maske a khase ho netefatsa ts'ireletso ka nako e ts'oanang.
