Ukusebenza kokudla nokupakishwa
Imboni yokusebenza kokudla izuzisa kakhulu kusuka ekusebenziseni i-PTFE Film Tape, ikakhulukazi kwizicelo zokupakisha. Izakhiwo ezingezona ezinamathe amatayela zikwenza kube yisinqumo esihle kakhulu sokufaka imishini yokuvalwa kokushisa, ukuvikela izinamathiseli kanye nezinto zokupakisha ezincibilikisiwe ekunamatheleni ezindaweni ezikhona. Lokhu kuphumela ekuhlanzeni, kwale ndima engaguquki futhi kunciphisa isikhathi sokuhlanza nokulungiswa.
Itheyiphu yefilimu ye-PTFE nayo isetshenziswa emishini yokusebenza kokudla ukudala izindawo ezingezona ezinamathele noma izithiyo zokuvikela. Ukuthobela kwayo kwe-Chemical Invertness kanye ne-FDA kwenza kube phephile ukusetshenziswa ezinhlelweni zokuxhumana zokudla, ukuqinisekisa ukuthi azikho izinto eziyingozi ezifakwa kwimikhiqizo yokudla. Ngaphezu kwalokho, ukumelana kwezinga lokushisa kwetheyiphu kuvumela ukuthi isetshenziswe ezindaweni ezishisayo nezibandayo zokudla, ukuhlinzeka ngezindlela zokuhlobisa imigqa ehlukahlukene yokukhiqiza.
Izinzuzo kanye nokucatshangelwa lapho usebenzisa i-PTFE Film Tape
Izinzuzo Zokukhetha i-PTFE FIED PAIP
I-PTFE film tape inikeza izinzuzo eziningi ezenza kube yikhethelo elikhethwayo lezicelo zokubekwa uphawu kwamakhemikhali. Ukumelana kwayo okuhlukile kwamakhemikhali kuqinisekisa ukuvikeleka okuhlala isikhathi eside ezintweni eziningi ezilimazayo, kunciphisa isidingo sokufakwa kabusha kanye nokunciphisa izindleko zokulungisa. Ukuqina kwezinga lokushisa kwetheyiphu kuvumela ukuthi yenze ngokuthembekile ekushiseni okwedlulele nokubanda, okwenza kube lula ngezindawo ezihlukene zezimboni.
Izakhiwo eziphansi nezingezinhle ezinamathela ethempeli lefilimu le-PTFE zineqhaza elithuthukisiwe ezinhlelweni zemishini nezinqubo zokupakisha. Lokhu kungaholela ekunciphiseni ukugqokwa kwemishini, ukusetshenziswa kwamandla okuphansi, nokukhiqiza okwengeziwe. Ngokwengeziwe, izakhiwo zikagesi zetheyipu zikwenza zibalulekile kuzinhlelo zokusebenza lapho kutholakala khona ukuvikelwa ku-electromagnetic.
Amasu wokufaka kanye nokufakwa
Ukuze wandise ukusebenza ngempumelelo kwetheyiphu yefilimu ye-PTFE , uhlelo lokusebenza olufanele kanye namasu wokufaka abalulekile. Ingaphezulu elizovalwa kulo kufanele lihlanzwe kahle futhi yomiswe ngaphambi kokusebenzisa itheyipu ukuqinisekisa ukunamathela okuphelele. Lapho usonga amapayipi noma ukufakwa, kubalulekile ukufaka itheyiphu enokungezwani okungaguquki kanye nokugqagqana ngakunye kuphenduka cishe ama-50% ukudala uphawu olunokwethenjelwa.
Okwezicelo ezicindezelwe kakhulu, izingqimba eziningi ze-PTFE film tape zingadingeka ukufeza izinga olifunayo lokubekwa uphawu. Kubalulekile futhi ukuthi ubheke ukuqondiswa kokugeleza koketshezi lapho usebenzisa i-tepi ukuze uxhumeke ukuxhumana, njengoba uhlelo lokusebenza olungalungile lungaholela ekuthuleni kokuvuza noma ukuthuthwa kwetheyipu. Ukulandela imihlahlandlela yomenzi kanye nemikhuba emihle yemboni kubalulekile ukuze kufinyelelwe imiphumela emihle nge-PTFE film tape.
Ukulinganiselwa kanye nezinye izixazululo
Ngenkathi i-PTFE film tape iguquguqukayo kakhulu, inokulinganiselwa okuthile. Kuhlelo oluphakeme kakhulu lwengcindezi noma lezo ezibandakanya amakhemikhali athile anolaka, ezinye izixazululo zokubopha uphawu zingadingeka. Isibonelo, ukunwetshwa kwe-PTFE (Ettfe) ama-gaskets noma izimpawu ezikhethekile ze-fluoropolymer zingahle zilungele izinhlelo zokusebenza ezithile eziphezulu zokusebenza.
Kubalulekile futhi ukuthi uqaphele ukuthi itheyiphu yefilimu ye-PTFE kungenzeka ingabi yisinqumo esihle kakhulu sokufaka izinhlelo zokusebenza ezibandakanya ama-oxidizizing agents noma ama-alkali, njengoba lokhu kungahle kungcolise lokho okuqukethwe. Ezimweni ezinjalo, ezinye izinto zokwakha noma izixazululo ezikhethekile zokubopha kufanele zibhekwe. Ukubonisana nabakhiqizi beTeflon Tape noma ochwepheshe bezinto zokwakha kungasiza ekukhetheni isisombululo esifanelekile kakhulu sokubekwa uphawu kwezinhlelo zokusebenza eziyinselele.
Ukugcina
I-PTFE film tape ithole kahle idumela layo njengesikhali esiyimfihlo sokubekwa uphawu kwamakhemikhali emikhakheni ehlukahlukene. Inhlanganisela yayo eyingqayizivele yokumelana kwamakhemikhali, ukuqina kwezinga lokushisa, kanye nezinto eziphansi zokuphambanisa kwenza kube yizinto ezibalulekile zokubhekana nezinselelo zokubopha ezindaweni ezinokhahlo. Ukusuka ezingubeni zokucubungula amakhemikhali ezisetshenzisweni ze-aerospace nezindawo zokupakisha zokudla, i-PTFE film tape iyaqhubeka nokudlala indima ebalulekile ekuqiniseni ukuphepha, ukusebenza kahle, kanye nokwethembeka.
