Kupititsa patsogolo PTFE Adhesive Tape Yogwira Mphamvu - Kupaka ndi Kuchiritsa Njira Kukhathamiritsa

Kugwira mphamvu - kuthekera kwa tepi yomatira kukana kumeta ubweya ndikukhalabe pamalo olemedwa nthawi zonse, makamaka pa kutentha kokwera - ndi imodzi mwazinthu zofunika kwambiri zogwirira ntchito. Tepi yomatira yotentha kwambiri ya PTFE . Kusagwira bwino mphamvu kumabweretsa kutsetsereka kwa tepi, zotsalira zomatira, ndi kuipitsidwa kwa zida.

Mfundo yayikulu pakuwongolera mphamvu yogwira ndi iwiri: kukulitsa mphamvu yolumikizana ya zomatira ndikulimbitsa mphamvu yolumikizirana pakati pa zomatira ndi gawo lapansi la PTFE..

Aokai PTFE yakonza njira zonse zokutira ndi kuchiritsa kuti zikwaniritse magwiridwe antchito apamwamba. Bukuli lili ndi mayankho mwadongosolo m'magawo awiri ofunikira opangira.

Kukonzekera kwa Coating Process - Kumanga Maziko

Njira yokutira imatsimikizira mwachindunji kapangidwe kake, makulidwe ofanana, ndi mphamvu yomangirira ndi gawo lapansi - maziko amphamvu yogwira bwino.

1. ❖ kuyanika koyambira - njira yaikulu yothetsera kusamata kwa PTFE

PTFE imakhala ndi mphamvu zotsika kwambiri (18-20 dynes/cm), zomwe zimapangitsa kuti zomatira zikhale zosavuta kupemba chifukwa cha kumeta ubweya wambiri. Njira yokutira yoyambira iyenera kukhazikitsidwa musanayambe kupaka zomatira pamwamba.

• Kusankha koyambira: Silane coupling agents kapena zoyambira zapadera za silikoni (njira zosakanikirana ndi utomoni wa tackifying ndi reactive silane) zimatengedwa kwambiri. Powonjezera-ochiza silicone PSA, vinyl kapena epoxy functional silane-based primers amakonda.

• Mfundo zazikuluzikulu zowongolera:

  • Filimu yoyambira yowonda kwambiri: Yesetsani makulidwe a filimu yowuma mkati mwa 0.5-2 μm - choyambira chochulukirapo chimapanga malire ofooka omwe amachepetsa mphamvu yogwira.

  • Kuyanika kokwanira: Zosungunulira zosungunulira bwino komanso zosungunulira zoyambira / zolumikizirana musanakutire pamwamba, kupewa zosungunulira zosungunulira kusamuka kupita ku zomatira zapamwamba.

  • Kuchiza kwapaintaneti + zokutira zoyambira: Chitani chithandizo cha plasma pa intaneti kapena corona pa gawo lapansi la PTFE nthawi yomweyo musanagwiritse ntchito poyambira kuti mupewe kuyatsidwa kwapamtunda.

2. Kuwongolera molondola kwa makulidwe a zomatira ndi kufanana

Kugwira mphamvu nthawi zambiri kumakwera ndi makulidwe omatira, koma zokutira zokhuthala kwambiri zimakulitsa zomatira pansi pa kutentha kwakukulu ndikufooketsa kugwira ntchito.

• Makulidwe oyenera a zomatira zouma: Silicone PSA imapeza mphamvu yogwira bwino pakuwuma kwa 30-60 μm.

• Njira zokutira zolondola kwambiri: Gwiritsirani ntchito zokutira za koma, zokutira za slot kufa, kapena zokutira zolondola kwambiri za micro gravure kuti musunge kulolerana kwautali komanso kopingasa mkati mwa ± 2 μm . Kuchulukana kosagwirizana kumayambitsa kupsinjika, zomwe zimapangitsa kuthyoka kuyambira pamalo a thinnest panthawi yoyesa mphamvu.

3. Zomatira madzi pretreatment ndi kudyetsa dongosolo

• Vacuum defoaming: Degas zomatira zamadzimadzi pansi pa vacuum mutasakaniza kapena musanaphike kuti mupewe kufalikira kwa voids pakuchiritsa, komwe kumakhala ngati malo oyambira ming'alu pansi pa katundu wambiri.

• Kusakaniza ndi kusasitsa pamzere: Pazomatira zamagulu awiri a silikoni, perekani chosakaniza chosasunthika kuti mudyetse mwachindunji ndikuwongolera nthawi yamadzi okhalamo kuti muwonetsetse kuti mukuchita chimodzimodzi ndikuchotsa madera osagwirizana.

• Kasamalidwe kaukhondo: Valani mitu yotchinga yokhala ndi zotchingira zosagwira fumbi ndi madzi omatira zosefera kudzera pa makatiriji osefera a 5-10 μm kuti mupewe zinyalala zomwe zimabweretsa kupsinjika.

Kuthetsa Kukhathamiritsa kwa Njira - Kutseka Magwiridwe

Kuchiritsa kumatsimikizira kachulukidwe komaliza, kupsinjika kwamkati, ndi mamolekyu ang'onoang'ono otsalira - omwe amawongolera mwachindunji mphamvu zolumikizana komanso kukana kutentha kwambiri.

1. Kutentha kwapang'onopang'ono ndi kuchiritsa kosiyanasiyana

Chidziwitso chofunikira: Kutenthetsa kwa stepwise kumathandizira kupanga yunifolomu, maukonde owoneka ngati atatu mkati mwa zomatira, kumapereka magwiridwe antchito apamwamba kwambiri poyerekeza ndi kuphika kwapanthawi imodzi. Kutentha kosakwanira kumapangitsa kuti pakhale kusakanikirana kosakwanira komanso kusakanikirana kofewa; Kutentha kwambiri kungayambitse ukalamba womatira kapena kupsinjika kwakukulu kwamkati kuchokera ku kuchepa kosagwirizana ndi kutentha.

2. Chithandizo cha pambuyo pochiritsa ndi kusasitsa

• Kuchiza kwapamzere: Khazikitsani gawo la uvuni musanayambe kupiringa ndi kutentha pang'ono kuposa kutentha kwapamwamba kwambiri kuti mutalikitse mbiri yamatenthedwe ndikukwaniritsa kuyanjanitsa kwathunthu.

• Kuchiritsa kukhwima kwa mabala: Ikani mipukutu ya tepi mu ng'anjo yotentha nthawi zonse ( 40-60 ° C kwa maola 24-48 ) kuti isungidwe. Ndondomeko iyi:

  • Amamaliza zotsalira crosslinking anachita pang'onopang'ono

  • Imatsitsimula kupsinjika kwamkati komwe kumachitika chifukwa chakukula kosagwirizana ndi kutentha pakati pa gawo lapansi ndi zomatira

  • Amawongolera kwambiri ntchito yonyamula katundu kwa nthawi yayitali pansi pa kutentha kwakukulu

• Kuyimitsa kwapang'onopang'ono: Gwiritsani ntchito mphamvu pang'ono pa tepi yogubuduzika panthawi yakukhwima kuti muchepetse nkhawa.

3. Kuchiritsa mlengalenga ndi kuwongolera chilengedwe

• Kasamalidwe ka chinyezi chochepa: Pazomatira za silicone zochizira, chinyezi chapakati chozungulira chimatenga nawo gawo pakuwoloka, pomwe chinyezi chambiri chimayambitsa khungu mwachangu ndikulepheretsa kuchira. Zomatira za silikoni zowonjezera zimafunikira kupatulidwa kotheratu kwa sulfure ndi mankhwala okhala ndi nayitrogeni kuti apewe kupha poizoni.

4. Kuwongolera kupsinjika ndi kuchepa kwa nkhawa

PTFE filimu sachedwa elongation ndi shrinkage matenthedwe pansi kutentha.

• Kutumiza kwapang'onopang'ono: Sungani kugwedezeka kosalekeza komanso kochepa kwa gawo lapansi mkati mwa uvuni kuti musachiritsidwe pansi pa zomatira zotalikira. Pambuyo kuziziritsa, gawo lapansi likucheperachepera maphunziro amamatira kukakamira kukakamira / kukameta ubweya wamkati - kuchepetsa kwambiri mphamvu yogwira.

• Kutenthetsa kwa gawo lapansi: Yatsani gawo lapansi la PTFE kuti lifike pamwamba pang'ono kuposa kutentha kwamadzimadzi musanayambe kupaka kuti ❖ kuyanika kumanyowa ndikuchepetsa kutenthedwa kwamphamvu kwa kutentha pacholowera cha uvuni.

Mwachidule - Mndandanda wa Kuyika ndi Kuchiritsa Kukhathamiritsa

Aokai PTFE imagwiritsa ntchito njira zokometsera izi ndikuchiritsa kuti ipange tepi yomatira ya PTFE yokhala ndi mphamvu zogwirira ntchito. Kwa makasitomala omwe amafunikira kugwira ntchito kwakanthawi kotentha kwambiri, titha kusintha mawonekedwe oyambira, makulidwe a zomatira, ndikuchiritsa ma profiles kuti akwaniritse zomwe mukufuna.

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

Ngati mukufuna kudziwa mwatsatanetsatane, zochitika ntchito ndi mayankho makonda athu zonse mankhwala osiyanasiyana nsalu, PTFE mkulu-kutentha zomatira tepi, PTFE high-kutentha mauna lamba, msokonezo kutentha atolankhani lamba, single-mbali PTFE nsalu, mkulu-kutentha zosagwira nsalu, PTFE mkulu-kutentha zomatira tepi, PTFE mkulu-kutentha mauna lamba, msokonezo kutentha atolankhani lamba, single-mbali PTFE nsalu, mkulu-kutentha zosagwira nsalu, kukhudzana ndi magalasi zosamva kutentha, kukhudzana ndi magalasi osamva kutentha, chonde tilankhule ndi ife.
