Bophelong ba letsatsi le letsatsi re ka atisa ho bona ptfe tube, kahoo, ptfe tube ka tshebetso ya ho sebetsa re lokela ho ela hloko lintho tse bohlokoa?
Ts'ebetsong ea kaho ea phala ea tšepe ea PTFE, lintlha tse latelang li hloka ho ela hloko:
1. phala ea tšepe e sa tsitsang ho ea ka boholo ba 'nete ba thepa, phala ea tšepe le tjheseletso ea selikalikoe, selikalikoe se ka sebelisa mochini oa argon arc welding, welding splash ka faele ho hloekisa, le fillet weld e sekhutlong se chitja, ha e na bohale. bohale.
2. Etsa lesoba le lenyenyane qetellong ea phala ea tšepe, e tšoaee ka ho hlaka, 'me u se ke ua e thibela.Sekoti sena se sebelisetsoa ho ntša khase e setseng pakeng tsa phala ea tšepe le phala ea tetrafluoroethylene nakong ea ho futhumatsa, 'me e sebelisetsoa ho shebella hore na pipe ea tetrafluoroethylene e senyehile kapa e lutla nakong ea teko ea khatello.
3. pipe ea tšepe e lokela ho kopanngoa pele ho lesela.Lenonyeletso le tla kopanngoa le pampiri ea khauta ea asbestos ea botenya bo loketseng, e le hore e lumellane le litlhoko tsa boholo ba kakaretso ka mor'a lesela.
4. ka mor'a kopano ea seamless tšepe phala ho lehlabathe ho phatloha kalafo, ho tlosa ka hare lerako mafome, 'me joale ka moea petelitsoe ho hloekisa tube cavity.Kenya tetrafluoroethylene tube ka har'a tube ea tšepe.Haeba phala e 'ngoe ea tetrafluoroethylene e se chitja 'me e ke ke ea kenngoa, metsi a chesang, mouoane kapa sebōpi se futhumatsang se lokela ho sebelisoa ho futhumatsa phala ea tetrafluoroethylene, mocheso oa ho futhumatsa ha o fete 100 ℃.
5. Nahana ka bolelele ba flanging ha u khaola phala ea teflon.Ka kakaretso, bolelele ba 35-40 bo behelloa ka thōko ka holim'a lesale la ho cheselletsa.Gasket ea khauta ea asbestos e lokela ho behoa holim'a tube ea TEflon pele e fofa.Ho phethola teflon tube ka mehato e 'meli, pele ho tloloko, sena se betsa ho sebelisa sekotoana sa aluminium se entsoeng ka tapered.Ha flanging, futhumatsa vivipary ka lelakabe la oxyacetylene.Mocheso oa mocheso o lekanngoa ka semiconductor surface thermometer.Mocheso ha oa lokela ho ba holimo haholo.Mocheso o lokela ho laoloa pakeng tsa 260 ℃ le 280 ℃.Ha o ntse o fofa, tobetsa butle ho theosa le seaparo sa tsoalo se futhumetseng.Ha seaparo sa tsoalo se fihla moeling oa reng ea welding, u se ke ua hlola u hatella hape.Ka nako ena, e pholile ka metsi 'me u tlose thepa ea pelehi ha e pholile ho fihlela mocheso o phelang.The flanging ea mohato oa bobeli ka ho eketsehileng plasticizes nozzle.Ena e bataletse.
6. ka mor'a ho futhumatsa, butle-butle u hatelle fatše 'me u hatelle fatše ka ho feletseng, ebe u pholile ka metsi ho mocheso o potolohileng, ebe o tlosa polaka.
7. Phaephe e nang le poleiti e ntle e foufetseng, e kenang ka har'a silindara e khethehileng ea ho futhumatsa, e hokahaneng le tube e hatelitsoeng ea moea, e futhumatsang silinda ka mokhoa oa ho futhumatsa maqhubu, e le hore mocheso o akaretsang oa liphaephe o fihle ho 280 ℃, ebe butle-butle o feta. Moea o hatelitsoeng oa 8-LOKGF/cm2.Beha tetrafluoron tube ka tanka ea metsi, qoelisa tube ka metsing, butle-butle u fete moeeng o hatelitsoeng oa 15kgf / cm2, hlahloba hore na ho na le li-bubble ka sekoting, haeba ho fumanoa, ho paka hore tetrafluoron tube e robehile.Lebaka ke haholo-holo ka lebaka la mocheso o sa lekaneng kapa lebelo la inflation ka potlako haholo.Pipe ea tšepe e nang le line e tla koaloa lipheletsong tse peli ka lepolanka le foufetseng la lehong ho thibela tšenyo ea pipe ea tetrafluoron.
