Emugqeni wokupakisha ohamba ngokushesha, isivali-manzi sokushisa siyibhodlela. Ngaso sonke isikhathi uma ipulasitiki encibilikisiwe inamathela kumbese wokuvala, ulayini uyama ukuze ukhuhlwe - ukubulala umkhiqizo. Zonke izimpawu ezimbi zibuyisela izikhwama ukuze zisetshenzwe kabusha. Wonke amafa agugile abiza izinkulungwane ukushintshwa.
Isixazululo silula ngokukhohlisayo: sebenzisa Itheyiphu ye-PTFE yokushisa okuphezulu endaweni yokuvala. Lolu ungqimba oluncane lwengilazi ye-fiberglass ehlanganiswe ne-PTFE, ene-adhesive abicah enezinga eliphezulu lokushisa, iguqula inqubo yokuvala ukushisa.
I-Aokai PTFE inikeze itheyiphu ye-PTFE kubakhiqizi bempahla yokupakisha nakubasebenzisi bokugcina iminyaka. Lesi sihloko sihlanganisa amavelu ezinhlelo zokusebenza ezine eziwumgogodla - ukukhishwa okunqanda induku, ukuvikelwa kwemishini, ikhwalithi yophawu, nokungqubuzana okuphansi - kanye nemibandela yokukhetha ukhiye (i-substrate, izinga lokushisa, okunamathelayo, izici zemishini) ukukusiza ukhethe itheyipu elungile yomugqa wakho wokuvala.
Amanani Amane Okusebenza Abalulekile we-PTFE Tape Ekuvaleni Kokushisa
1. Qeda I-Adhesive Residue - Ukukhiqiza Okuqhubekayo Okusebenza Kakhulu
Lena inzuzo eqondile ye-PTFE tape. Amafilimu okupakisha ahlanganisa i-PE, PP, PET, namafilimu ayinhlanganisela ye-aluminium athambekele ekuthambeni futhi anamathele ezindaweni ezingenalutho zokuvala zensimbi ngaphansi kokushisa, okubangela ukugqashuka kwesikhwama, ukuklebhuka kwefilimu, kanye nesikhathi sokuphumula esivamile sokuhlanza.
Isiza kanjani i-PTFE: Amandla aphezulu aphansi kakhulu (18-20 dynes/cm) axosha amapulasitiki ancibilikisiwe nezinamatheliso ezincibilikayo ezishisayo. Ifilimu ikhipha ngokuhlanzekile wonke umjikelezo.
Umphumela: Yenqaba ukwehla kwezinga; isikhathi sokumisa umshini sokuhlanza sincishiswa ngo-80-90%.
2. Vikela Izingxenye Zokuvala Ukushisa - Nweba Impilo Yezisetshenziswa
Ummese wokuvala noma ibha yokushisisa iyingxenye yensimbi enembile. Ngokuhamba kwesikhathi, ukungqubuzana okuvela kumafilimu nezindwani zokusika kuyayiqeda, futhi i-oxidation/ukugqwala kugibela phezulu.
I-PTFE njengesendlalelo sokuvikela esisebenzisekayo: Itheyiphu isebenza njengephedi yokuguga ebiza kancane, eshintshwayo. Ukushintsha itheyiphu kuthatha imizuzu futhi kubiza amasenti uma kuqhathaniswa nokulungisa noma ukufaka esikhundleni sokufa okuvalwa ngokwezifiso ($500-$5,000+).
Umphumela: Impilo yesevisi yezisetshenziswa inweba kakhulu; izikhawu zokushintshwa ziyandiswa.
3. Homogenize Heat Distribution - Thuthukisa Seal Ukuvumelana
Itheyiphu ye-PTFE eqiniswe nge-fiberglass ye-Premium inezimfanelo ezimaphakathi zokwehlisa kanye nokusabalalisa okushisayo. Inxephezela ukungalingani okuncane phakathi kommese wokuvala kanye nefilimu yokupakisha ezingeni elincane.
Indlela esebenza ngayo: Itheyiphu isakaza kokubili ukushisa nokucindezela ngokulinganayo endaweni yokuvala.
Umphumela: Ama-seal ahlanzekile, angaguquguquki anamandla afanayo - awekho ama-seal angaphelele (avuzayo) noma ashise ngokweqile (amaphinifa).
4. I-Lower Friction Coefficient - I-Smooth Film Conveying
I-PTFE's ultra-low kinetic friction coefficient (μ≈0.05-0.10) ibalulekile ngale kwebha yokuvala. Isetshenziswa kabanzi ekwenzeni amakholomu nemikhono yeshubhu yemishini eqondile yokugcwalisa ifomu (VFFS).
Izinzuzo: Yehlisa ukumelana nokusebenza kwefilimu yokupakisha; ivimbela i-deformation yokwelula ifilimu; kunciphisa ukwakheka okumile (uma kusetshenziswa i-anti-static grade).
Umphumela: Ukuphakelwa kwefilimu okuzinzile, ukugcwala okuncane.
I-Aokai PTFE inikezela ngetheyiphu ye-PTFE esekelwe nge-fiberglass ikakhulukazi izinhlelo zokusebenza zokuvala ukushisa. I-silicone PSA yethu ixhunywe ku-260°C isevisi eqhubekayo, yaqinisekiswa ngokuhlolwa kokuguga kokushisa kwamahora angu-1,000 ngaphandle kokunamathela okunamathelayo. Ibanga elimnyama le-anti-static (ukumelana nobuso 10⁶-10⁹ Ω) liyatholakala emigqeni yefilimu enesivinini esikhulu.
Izimo zokuvala ukushisa ziyahlukahluka kakhulu ngezinga lokushisa lokusebenza, amandla okucindezela, kanye nesivinini sokugijima. Ukucaciswa okulandelayo kufanele kuqinisekiswe ngesikhathi sokukhetha.

Kafushane , itheyiphu yezinga lokushisa eliphezulu ye-PTFE esetshenziswa emimeseni evala ukushisa nemicu yokuvala iletha amanani amane abalulekile: ukukhishwa okunqanda ukuqina (kuvimbela ukuphumula), ukuvikelwa kwemishini (konga ukufaka esikhundleni sokufa okubizayo), ikhwalithi yophawu oluthuthukisiwe (ukushisa/ukucindezela okuphansi), kanye nokungqubuzana okuphansi (okuphakelayo kwefilimu okubushelelezi).
Ngokuvalwa kokushisa okujwayelekile kwephakheji, itheyiphu ye-PTFE esekelwe nge-fiberglass ene-silicone enamathelayo ku-0.13 mm noma u-0.18 mm ukujiya ihhashi lomsebenzi elifakazelwe. Ngemigqa enokusikwa njalo noma emile kakhulu, thuthukela ku-0.25 mm noma ibanga elimnyama eliphikisana ne-static. Njalo qinisekisa izinga lokushisa eliqhubekayo lokunamathelayo – i-silicone PSA, hhayi i-acrylic.
