Kodi Tepi Yomatira Yotentha Kwambiri ya PTFE Ndi Yotani?

Liti PTFE high-temperature adhesive tepi imagwiritsidwa ntchito pazinthu zomwe zimaphatikizapo kukanikiza kosalekeza, kukakamiza, kapena kulemedwa kosalekeza - monga kuyika zotchingira pamalo pa chitoliro chotentha, kapena kuchita ngati chomangira chokhazikika pansi pamavuto okhazikika - vuto lobisika limatha kuwonekera: kukwawa..

Creep ndikusintha kwapang'onopang'ono, kokhazikika kwa zinthu zomwe zimachulukitsidwa nthawi zonse. Pa kutentha kwa chipinda, tepi ya PTFE ingawoneke yokhazikika. Koma pa 200 ° C kapena 260 ° C - momwe zimagwirira ntchito - zosanjikiza zomata zimatha kufewetsa ndikuyenda, ndipo gawo lapansi la PTFE limatha 'kutuluka kozizira' (kutsika pansi pa malo osungunuka).

Aokai PTFE yayesa machitidwe oyenda maola masauzande ambiri. Nkhaniyi ikufotokoza momwe kukwawa kumawunikiridwa, momwe zomatira ndi gawo lapansi lililonse zimathandizira, komanso ndi mapangidwe a tepi omwe amakana kukwawa bwino.

Kodi Kukwera mu PTFE Tepi - Miyeso iwiri

Creep kwenikweni amatanthauza kuyankha kwa viscoelastic kwa zinthu. Zomatira zomatira ndi gawo lapansi zimagwira ntchito pamakina osiyanasiyana, komabe zonsezi zimakhudza kwambiri kukana kwa deformation.

Vuto logwira ntchito: Matepi a PTFE nthawi zambiri amakumana ndi katundu wokhazikika pa 200-260 ° C, kupitirira malire a zomatira wamba zotengera kukakamiza. Kuyesedwa kowonjezereka kwa kutentha kumafunika.

Zida Zomatira - Silicone PSA

Matepi ambiri omatira a PTFE amatenga zomatira zomata za silikoni, zomwe kukana kwawo kutentha kwambiri kumadalira izi:

Chotengera chachikulu: Zomatira za silikoni zomangika pang'onopang'ono zimawonongeka mwachangu pakutentha kokwera. Ma tepi apamwamba odana ndi creep amagwiritsa ntchito silikoni yolimba kwambiri yokhala ndi zomangira zolimbitsa thupi komanso zokutira zopyapyala zoyendetsedwa bwino.

Tepi ya Aokai PTFE yotentha kwambiri imagwiritsa ntchito silikoni ya PSA yolimba kwambiri yokhala ndi silika yokhala ndi fumed. Kuyesa kodziyimira pawokha kumeta ubweya wa static pa 260 ° C (katundu wa 1000g, kuphatikizika kwa 12.5 × 25 mm) kumawonetsa > maola 150 mpaka kulephera - koyenera kufunsira ntchito zolemetsa zotentha kwambiri.

Katundu Wagawo Lapansi - PTFE Coated Fiberglass vs. Pure PTFE Film

Magawo awiri odziwika amagwiritsidwa ntchito pa matepi a PTFE, okhala ndi magwiridwe antchito osiyanasiyana:

Kwa gawo lapansi lolimbitsidwa ndi fiberglass, kukana kukwawa kumatsimikiziridwa ndi:

Chotengera chachikulu: Pazowonjezera zotentha kwambiri, musagwiritse ntchito tepi yoyera ya PTEF - idzakwawa mosasinthika. Nthawi zonse sankhani tepi ya PTFE yolimbikitsidwa ndi fiberglass.

Mwachidule - Momwe Mungatsimikizire Kukaniza kwa Creep mu PTFE Tepi

Malangizo othandiza: Pazogwiritsa ntchito nthawi zonse zotentha kwambiri (mwachitsanzo, kukulunga kwa chitoliro pansi pa kukanidwa, kukhala ndi zigawo pazitsulo zotenthedwa), pemphani deta yometa ubweya wa static pa kutentha kwanu ndi katundu wanu. Tchulani tepi ya PTFE yolimbitsidwa ndi fiberglass, osati tepi ya kanema. Onetsetsani kuti zomatirazo ndi silikoni yolimba kwambiri yokhala ndi zodzaza.

Mwachidule , kukwawa kukana kwa PTFE mkulu-kutentha zomatira tepi pansi kwa nthawi yaitali zonse katundu zimadalira zigawo ziwiri. Silicone PSA wosanjikiza uyenera kukhala ndi kachulukidwe kakang'ono ka crosslink, kulimbikitsa zodzaza (silica fumed), ndi zokutira zopyapyala za yunifolomu kuti zithetse kutulutsa kwa viscous. Gawo lapansi liyenera kukhala la fiberglass-reinforced PTFE - filimu yoyera ya PTFE idzakumana ndi kuzizira kosasinthika pakutentha kwambiri. Chigoba cha fiberglass chimanyamula katundu ndikupangitsa gululo kukhala lokhazikika.

Posankha tepi ya PTFE ya ntchito zokhazikika zotentha kwambiri, osakhazikika pa tepi yoyera ya PTFE. Nthawi zonse funsani za data ya static shear pa kutentha kwanu. Ndipo kumbukirani: kugwirizana pakati pa zomatira ndi gawo laling'ono ndilofunikanso - malo opangira ma primer amalepheretsa kutsetsereka.

Mukufuna tepi ya PTFE yosamva kutentha kwanthawi zonse? Aokai PTFE imapereka tepi yolimbitsidwa ndi fiberglass yokhala ndi silikoni ya PSA yapamwamba kwambiri ya crosslink-density, yotsimikiziridwa ndi kuyesa kwa 260°C static shear. Lumikizanani nafe ndi katundu wanu, kutentha, ndi nthawi yomwe mukufuna.

Nkhani yoperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna zina, maupangiri ogwiritsira ntchito, ndi njira zothetsera makonda amtundu wathu wazinthu zonse kuphatikiza nsalu ya PTFE yotentha kwambiri, tepi yomatira ya PTFE, lamba wa PTFE mesh conveyor, lamba wa fuser wopanda msoko, nsalu ya PTFE ya mbali imodzi, lamba wosamva kutentha kwambiri ndi lamba wosamva kutentha kwa fiberglass kuti mulumikizane nafe:

• Bambo Liu: +86 13705266308

Timatsatira ukatswiri ndi umphumphu, odzipereka kuti apereke mayankho okhazikika omwe amakhazikika komanso chithandizo choganizira pambuyo pogulitsa!
