Amapulatifomu angasogwini, imikhumbi, izinjini zomoya zasogwini, nezinto zokusebenza zobunjiniyela basolwandle zibhekene nesitha esingapheli: isifutho sikasawoti . Igqwala izinsimbi, yehlisa izinga lokunamathela, futhi inciphise ukuphila kwemishini. Angakwazi Itheyiphu ye-PTFE yokushisa ephezulu isinde kulezi zimo ezinzima?
Impendulo emfushane: i-PTFE substrate ngokwayo cishe ayinakusha esifutheni sikasawoti. Kodwa ukusebenza okuphelele kwetheyiphu kuncike kakhulu kuhlobo lokunamathela kanye nekhwalithi yokufaka.
I-Aokai PTFE inikeze amateyipu e-PTFE ezicelo zasolwandle iminyaka. Lesi sihloko sichaza ukumelana nesifutho sikasawoti, ukukhetha okunamathelayo, ukulungiswa kwendawo, ukuvala uphawu emaphethelweni, nokugcinwa kahle - ukuze ukwazi ukufeza ukwethembeka kwesikhathi eside ezindaweni ezisogwini nasogwini.
Ukumelana Nesifutho Sosawoti – PTFE Substrate vs. Adhesive
1. I-PTFE Substrate – Ayizweli Ngokuphelele
I-PTFE ibonisa ukungabi namakhemikhali okuvelele. Cishe ayisebenzi ngesifutho samanzi olwandle nosawoti, futhi izinga lokumunca amanzi lingaphansi kuka -0.01% . Iphinde ilethe okuhle kakhulu kwe-UV nesimo sezulu. I-PTFE substrate ngokwayo imelana ngokuphelele nesifutho sikasawoti - akukho ukugqwala, ukuwohloka, noma ukulahlekelwa izakhiwo ezibonakalayo.
Idatha engukhiye: I-PTFE ayibonisi ukuguqulwa kwesisindo esilinganisekayo noma ukuwohloka kwendawo ngemva kwezinkulungwane zamahora kumagumbi okufuthwa ngosawoti.
2. Okunamathelayo - Isixhumanisi Esibuthakathaka
Ukumelana okuphelele kwe-salt spray ye-tape kuncike ikakhulukazi kuhlobo lokunamathela:
Uhlobo Lwezinamathiselo |
Ukumelana Nesifutho Sosawoti |
Ukufaneleka Kwasolwandle |
I-Silicone PSA |
Kuhle kakhulu - ukumelana nokuhlolwa kwesifutho sikasawoti samahora angama-500-1000+; ukugcinwa kwamandla we-peel>80% |
✅ Inketho ekhethwayo |
I-Acrylic PSA |
Okumpofu - i-hydrolysis, ukufuduka kwe-plasticizer, ukulahlekelwa okukhulu kokunamathela ngaphansi kokushisa okuphezulu / umswakama / isifutho sikasawoti |
❌ Akunconyiwe |
Kungani i-silicone iwina: Isistimu ye-silicone exhunywe ngokuphambanayo i-hydrophobic ngokwemvelo, imelana ne-UV, futhi izinzile yonkana -70°C kuya ku-260°C. Igcina ukunamathela nokuvumelana nezimo ngisho nangemva kokuchayeka isikhathi eside kwesifutho sikasawoti.
Kungani i-acrylic yehluleka: Izinamatheliso ze-acrylic ezivamile zithola i-hydrolysis ezindaweni ezinomswakama ophezulu. Isifutho sikasawoti sisheshisa ukuwohloka kwamabhondi e-ester, okuholela ekuthambiseni okunamathelayo, ekufudukeni, nasekuhlulekeni kwebhondi ekugcineni.
I-Aokai PTFE isebenzisa kuphela i-PSA ye-silicone esebenza kahle kumateyipu ethu ebanga lasolwandle e-PTFE. Siqinisekise amateyipu ethu ngokuhlola okuzimele kwesifutho sikasawoti esingathathi hlangothi samahora ayi-1000 nge >80% yokugcinwa kwamandla ekhasi - imibhalo etholakala uma icelwa.
Izidingo Zokufaka Isicelo Sezindawo Zokufutha Kasawoti Kasawoti Wasolwandle Ophakeme
Ukuze uthole isevisi enokwethenjelwa kumapulatifomu angasogwini, imikhumbi, izinsiza zamandla omoya osogwini, kanye nemishini yobunjiniyela basolwandle, ukulawulwa okugcwele kwenqubo okumboza ukukhethwa kwezinto, ukwakhiwa, ukuklama, nokugcinwa kuyadingeka.
1. Ukukhetha Izinto
Imfuneko |
Ukucaciswa |
Okunamathelayo |
Isekelwe ku-silicone, ukumelana nezinga lokushisa ≥260°C, ukumelana isikhathi eside nomswakama ophezulu, isifutho sikasawoti, kanye ne-UV |
I-substrate |
Ifilimu ye-PTFE ehlanzekile noma indwangu ye-fiberglass efakwe kwikhwalithi ephezulu ye-PTFE - amandla okusebenza aphezulu, ukungeneka okuphansi, isimo sezulu esiphezulu |
Izicelo zokufakwa kukagesi |
Khetha ukushuba kwetheyiphu ngokuya ngezinga le-voltage; bheka ibanga elidala ukuvimbela ukuqhekeka komhlaba ngaphansi kwesifutho sikasawoti kanye nezimo ezimanzi |
2. Ukwelashwa Okungaphezulu
Susa ngokuphelele amafutha, usawoti, nokugqwala endaweni yokubopha. Qinisekisa ukuthi indawo yomile ngokuphelele.
Sula ngokuphindaphindiwe nge-ethanol engena-hydrous noma i-acetone kuze kube yilapho kungasekho ukungcola.
Ezindaweni zensimbi: Kunconywe ukuthi wenziwe roughen ngokuqhunyiswa kwesihlabathi noma ukugaywa kwesihlabathi (80-120 grit) ukuze kuthuthukiswe amandla okunamathisela okwemishini.
Ezimweni ezimbi kakhulu: Faka isicelo se-silicone primer ngaphezu kwalokho - kuthuthukisa kakhulu ukunamathela kokuqala kanye nokumelana nesifutho sikasawoti isikhathi eside ezindaweni zensimbi.
Kungani lokhu kubalulekile: I-interface ye-tape-substrate iyindawo ebuthaka kakhulu ezindaweni zesifutho sikasawoti. Ukwelashwa kwendawo enganele kuvumela isifutho sikasawoti ukuthi singene eduze kwesixhumi esibonakalayo, okubangela ukugqwala kwezingxenye ezingaphansi zensimbi noma ukuhlukaniswa kwesendlalelo sokunamathela.
3. Inqubo yokwakha
Isinyathelo |
Imfuneko |
Kungani |
Izimo zemvelo |
Izinga lokushisa le-ambient ≥10°C, umswakama ohlobene ≤75%. Ungasebenzisi ezindaweni ezinamazolo noma ezimanzi |
Ivimbela ukujiya ngaphansi kwe-tape |
Ukuqedwa kwebhamuza lomoya |
Roll noma itheyiphu ebushelelezi ngemva kokufaka isicelo ukuze ukhiphe wonke amabhamuza omoya |
Iqinisekisa ukuthintana okuqinile okungu-100%, azikho izikhala zesifutho sikasawoti esinganqwabelana |
Ububanzi bethanga |
≥10–15 mm. Faka ingcindezi eyengeziwe ezindaweni ezigqagqene. Uma uthanda, thambisa ingcina ngomoya oshisayo onezinga lokushisa eliphansi ngaphambi kokuyicindezela |
Ithuthukisa ukuvala ngokugqagqana |
Ukuvalwa komngcele (okubalulekile olwandle) |
Gcoba yonke imiphetho eveziwe nge -silicone engamelana nesimo sezulu |
Ivimbela ukungena kwesifutho sikasawoti eduze kwezindawo zokusebenzelana - isinyathelo esibaluleke kakhulu sokuthembeka kwesikhathi eside |
4. Izimiso Zokuklama Nokukhetha
Ububanzi be-tape - Kufanele bube bukhulu kunendawo evikelekile, igcine umkhawulo wokuvala ophelele okungenani ongu-5-10 mm ohlangothini ngalunye.
Ukunwetshwa kwe-thermal - Uma kubhekwa izinguquko ezinqala zokushisa phakathi kwezindawo ezikhanyiswe yilanga/ezinomthunzi kanye nemini/ubusuku, khetha amateyipu avumelana nezimo kahle ukuze ugweme ukuhlehla ekubhayisikilini okushisayo.
Ukugqwala kwe-Electrochemical - Uma isetshenziswa ezinhlelweni zokuvikela i-cathodic noma amalunga ezinsimbi ezingafani, qinisekisa ukuthi itheyipu inokumelana nokufakwa okuphezulu ngokwanele ukugwema ukugqwala kwe-galvanic.
5. Ukusebenza Nokugcinwa

Ukuvalwa komngcele |
Faka i-silicone sealant emelana nesimo sezulu kuzo zonke iziphetho eziveziwe - okungaxoxiswana ngazo zasolwandle |
Ukugcinwa njalo |
Hlola njalo ezinyangeni ezi-3-6; hlambulula amadiphozi kasawoti; ukulungisa umonakalo ngokushesha |
Ukushintshwa okuhleliwe |
Ngokusekelwe kokuhlangenwe nakho kwasendle - ungalindi ukwehluleka okubonakalayo |
Ngamafuphi , itheyiphu ye-PTFE yokushisa ephezulu inhle kakhulu endaweni yesifutho sasolwandle nesiphezulu - i-PTFE substrate imelana nosawoti, i-UV, kanye nomswakama ngokuphelele. Kodwa-ke, ukuthembeka kwesikhathi eside kwe-tape kuncike ekunamatheleni. I-Silicone PSA iyona kuphela inketho yezinhlelo zokusebenza zasogwini nezisogwini, ngokusebenza okuqinisekisiwe kwehora elingu-500-1000+ lokuhlola isifutho sikasawoti (>80% ukugcinwa kwekhasi). I-Acrylic PSA izohluleka phakathi nezinyanga.
Ngalé kokukhethwa kwe-adhesive, impumelelo idinga ukuhlanzwa okuphelele kwendawo kanye nokuqina, ukusetshenziswa okungenabhamuza, futhi - okubaluleke kakhulu - ukuvalwa konqenqemeni nge-silicone sealant ukuze kuvinjwe ukungena kwesifutho sikasawoti. Ukuhlola okuvamile nokushintshwa okuhleliwe kuqedela isu lokwethembeka.
Udinga itheyiphu ye-PTFE yesicelo sasolwandle noma sasolwandle? I-Aokai PTFE inikeza amateyipu e-silicone e-PSA PTFE agunyazwe ukumelana nesifutho sikasawoti. Xhumana nathi ngezimo zakho zemvelo, i-substrate material, nempilo yesevisi elindelekile ukuze uthole izincomo ezifanelana nawe.
Okuqukethwe kuhlinzekwe ngu I-Jiangsu Aokai New Materials Technology Co., Ltd.
Uma ufisa ukufunda kabanzi mayelana nemingcele enemininingwane, izimo zohlelo lokusebenza, nezixazululo ezenziwe ngokwezifiso zohlu lwethu oluphelele lomkhiqizo, okuhlanganisa izindwangu ze-PTFE ezishisa kakhulu, amateyipu we-PTFE, amabhande anezikhala we-PTFE, amabhande omshini wokuhlanganisa angenamthungo, izindwangu ze-PTFE ezinohlangothi olulodwa, ukumelana ne-high-temperature ne-fiber-tempers sicela uxhumane nathi.
