Inqubo yokukhiqiza ye-PTFE ikakhulukazi ihlanganisa lezi zinyathelo ezi-4 ezinkulu ezilandelayo:
1. i-monomer synthesis
I-PTFEi-polymerization ye-tetrafluoroethylene (TFE) i-polymerization ye-monomer yama-polymer compounds.i-monomer synthesis ye-TFE isinyathelo sokuqala senqubo yokukhiqiza ye-PTFE.Njengamanje, imboni ikakhulukazi isebenzisa indlela ye-electrolytic fluorination ukuze ilungiselele i-TFE monomer, okungukuthi, i-anhydrous hydrogen fluoride ne-ethylene ngaphansi kwezimo ezithile zokusabela kwe-electrolysis ukukhiqiza i-TFE monoma.
2.Ukusabela kwePolymerization
TFE monomer at izinga lokushisa elithile kanye nengcindezi, engeza catalyst and solvent, polymerization reaction.Ngesikhathi sokusabela kwe-polymerization, i-TFE monomer yenziwa i-polymerized ukuze yakhe isisindo samangqamuzana aphezulu i-PTFE, izinga lokushisa, ingcindezi, uhlobo lwe-catalyst kanye nokuhlushwa kokusabela kwe-polymerization nezinye izici zizothinta isisindo samangqamuzana, isakhiwo kanye nezakhiwo ze-PTFE.
3.Ngemva kokwelashwa
Ngemuva kokuthi ukusabela kwe-polymerization sekuqediwe, ukwelashwa kwangemva kokwelashwa kuyadingeka ukuze uthole imikhiqizo emsulwa ye-PTFE.Ngemuva kokwelashwa ikakhulukazi kuhlanganisa ukuwasha, ukomisa, ukuchotshozwa, ukusefa nezinye izinyathelo zokususa ama-catalysts, izinyibilikisi nokunye ukungcola ukuze uthole izinhlayiya zenhlaka ze-PTFE ezihlanzekile.
4.Inqubo yokubumba
Izinhlayiya ze-resin ze-PTFE zibunjwa ngaphansi kwezimo ezithile ukuze bathole okudingekayoPImikhiqizo ye-TFE.Izindlela zokubumba zihlanganisa i-extrusion, ukubunjwa komjovo, i-calendering nokunye, ngokusho kwezidingo ezahlukene zemikhiqizo ukukhetha indlela efanele yokubumba.Ukushisa kwenqubo yokubumba, ingcindezi, isivinini sokucubungula nezinye izici kuzothinta ukusebenza kanye nekhwalithi yemikhiqizo ye-PTFE.
Impahla eluhlaza ye-PTFE
I-Polytetrafluoroethylene (PTFE) resin yatholwa ngengozi ososayensi baseMelika elabhorethri ngo-1936, futhi manje umhlaba ungakhiqiza i-PTFE emazweni angaphansi kwama-20, iningi lawo okungamazwe athuthukile.I-China kuma-60s ukuze ikwazi kahle ubuchwepheshe bokukhiqiza futhi ibone ukukhiqizwa, isibe ngumthengi omkhulu we-PTFE, lapho imikhiqizo ephansi ibe ngaphezu kokufunwa, kodwa imikhiqizo eminingi ephezulu isadinga ukuthembela ekuthengisweni okuvela emazweni athuthukile. .
Izinto zamanje ze-PTFE ze-PTFE kanye nemikhiqizo zithengwa kwamanye amazwe zivela e-United States, Japan, kanye namazwe ase-Europe.Ngenxa yezindleko zokuthutha kanye nomjikelezo wokuhlinzeka, i-China ukungenisa okuvame kakhulu e-Japan, kanye nokungeniswa kwemikhiqizo yase-Japan kwemikhiqizo ye-PTFE yekhwalithi enhle ukuhlangabezana nesidingo sasekhaya sezinga eliphezulu.
Ngokusho kwempendulo yekhasimende lokugcina, imikhiqizo emandleni omshini wokusetshenziswa kwangempela kwezimo zokusebenza, ukumelana nokukhuphuka kanye nokuzinza okuphezulu nokuphansi kwezinga lokushisa, izinto ezingeniswa kwamanye amazwe zingcono kunempahla yasekhaya.
Ukuthenga ishubhu ye-PTFE efanele akukhona nje kuphela ngokukhetha imininingwane ehlukene yezinhlelo zokusebenza ezahlukene.Okuningi ukukhetha umenzi onokwethenjelwa.I-Besteflon Fluorine plastic Industry Co., Ltd. igxile ekukhiqizeni amapayipi namashubhu ekhwalithi ephezulu we-PTFE iminyaka engu-20.Uma kukhona imibuzo nezidingo, sicela ukhululeke ukuxhumana nathi ukuze uthole iseluleko esithe xaxa sochwepheshe.
