PTFE Tape Adhesion vs Kutentha: Momwe Mungasinthire

Jiangsu Aokai New Materials, katswiri wopanga tepi yotentha kwambiri ya PTFE, amagawana nzeru zaukadaulo kwa inu.

PTFE (Teflon) mkulu-kutentha tepi zambiri angagwiritsidwe ntchito mosalekeza mu kutentha osiyanasiyana -196 ℃ mpaka 260 ℃ . Mu ntchito zambiri, kutentha kukana malire a tepi amaletsedwa ndi zomatira wosanjikiza  osati PTFE gawo lapansi. Kuchita kwake kumatsatira malamulo omveka bwino okhudzana ndi kutentha:

Kuchita zomatira kumachepa pamene kutentha kumakwera  Ndi kutentha kowonjezereka, zomatirazo zimafewetsa pang'onopang'ono, zimayandama komanso zimawononga, zomwe zimapangitsa kuchepetsa mphamvu zogwirizanitsa. Macroscopically, izi zimawoneka ngati kutsika kwa kumamatira.

Zomatira  zosiyanasiyana zimakhala ndi kutentha kosiyana kwambiri:

 

Kupititsa patsogolo nthawi yogwira kutentha kwambiri , kukhathamiritsa kumachitika makamaka kuchokera kuzinthu zitatu: kupanga zomatira, magwiridwe antchito a gawo lapansi, ndi mawonekedwe omangirira.

1. Zomatira Zosakaniza: Kwezani Ulalo Wofooka

·  Sankhani makina omatira osamva kutentha kwambiri : Yang'anani zomatira zomatira za silicone kuti zizikhala zogwira ntchito kwanthawi yayitali.

:  Kusinthidwa kwa Fluorocarbon Sinthani zomatira za silikoni ndi mankhwala a fluorocarbon kuti mukweze kutentha kwa galasi (Tg) kufika pa 230 ℃. Pambuyo pa maola 48 akugwiritsa ntchito mosalekeza pa 260 ℃, kuchuluka kwa zomatira kumapitilira 85%.

·  Yambitsani maukonde ophatikizika : Pangani ma nano-scale crosslinking network kuti mupititse patsogolo mphamvu zolumikizana komanso kukameta ubweya wa zomatira pa kutentha kwambiri.

Onjezani  zolimbitsa matenthedwe : Phatikizani zolepheretsa phenol ndi zolimbitsa thupi zina mu fomula kuti mulepheretse kuwonongeka kwa okosijeni pansi pa kutentha kwakukulu.

2. Gawo Lapansi: Kwezani malire onse oletsa kutentha

Kusinthidwa kwa Nano  -filler : Onjezani nano silika, boron nitride nanotubes ndi nanoparticles mu gawo lapansi la PTFE kuti mupange mfundo zolumikizirana. Kutentha kosokoneza kutentha kumatha kuwonjezeka ndi 20-30 ℃, ndikusunga 90% ya kumamatira koyamba pa 260 ℃.

·  Chithandizo chophatikizira mamolekyulu : Unyolo wa ma molekyulu a Crosslink PTFE kukweza kutentha kosalekeza kwa ntchito mpaka 300 ℃.

·  Kulimbitsa CHIKWANGWANI : Onjezani 25% ulusi wagalasi kapena kaboni fiber kuti mulimbikitse kukana ndi 300%, ndikupangitsa kugwiritsa ntchito mosalekeza mpaka 280 ℃.

3. Interface & Structural Design: Limbikitsani kukhazikika kwa mgwirizano

·  Chithandizo cha gawo lapansi : Ikani mankhwala a plasma kapena etching pa PTFE kuti muonjezere roughness ndi zochitika zapamtunda, kulimbikitsa kumamatira kwapakati komanso kupewa delamination pa kutentha kwakukulu.

·  Onjezani chotchinga chapakati : Ikani wosanjikiza wodzipatula wa polyimide (PI) pakati pa gawo lapansi la PTFE ndi zomatira kuti mutseke zomatira kulowa ndi kusamuka pansi pa kutentha kwakukulu, kuwongolera kukhazikika kwadongosolo.

·  Konzani kamangidwe kamagulu : Landirani mawonekedwe amitundu yambiri: PTFE zokutira + kulimbikitsa gawo lapansi + kutentha kosasunthika kwapamwamba , kuti mugwirizane ndi kutentha kwa kutentha ndi ntchito yomatira mokwanira.

·  Chilolezo chowonjezera kutentha : Mzere wowonjezera wa PTFE ndi pafupifupi 10 kuposa chitsulo.

Sungani kusiyana kwa 0.15-0.3 mm  pamapangidwe apangidwe kuti mutulutse bwino kupsinjika kwa kutentha.

Zomwe zili pamwambapa zaukadaulo zimaperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Ngati mukufuna zambiri zokhudza magawo luso, zochitika ntchito ndi mayankho makonda a zonse mzere mankhwala - kuphatikizapo PTFE mkulu-kutentha nsalu, PTFE high-temperature tepi, PTFE high-temperature mauna lamba, chosakanizika fusing machine lamba, single-mbali PTFE nsalu, mkulu kutentha zosagwira magalasi lamba kukhudzana ndi galasi free lamba -

Nthawi zonse timatsatira malingaliro abizinesi a ukatswiri ndi kukhulupirika, ndikuyesetsa kukupatsirani mayankho amakampani omwe amasiyanitsidwa ndi ntchito yoganizira pambuyo pogulitsa.
