Momwe Mungasinthire Magwiridwe Obwereza Obwereza a PTFE High-Temperature Adhesive Performance

Tepi ya PTFE yotentha kwambiri imagwiritsidwa ntchito nthawi zambiri pamapulogalamu omwe imayenera kuchotsedwa ndikugwiritsidwanso ntchito kangapo - pa zosindikizira kutentha panthawi yakusintha, pamabedi osindikizira a 3D, kapena ngati masking osakhalitsa mumsonkhano wamagetsi. Komabe, pakapita maulendo angapo, matepi ambiri amatayika, amasiya zotsalira, kapena amalephera kulumikiza.

Nkhani yabwino: reusability ikhoza kusinthidwa bwino kwambiri kudzera mu kukweza kogwirizana mu miyeso inayi: zomatira zomatira , gawo laling'ono , lakumbuyo la zokutira kumbuyo , ndikugwiritsa ntchito moyenera & kukonza..

Aokai PTFE yapanga matepi osinthika a PTFE pogwiritsa ntchito mfundozi. Bukuli likufotokoza mbali iliyonse mwatsatanetsatane.

Kukhathamiritsa kwa Adhesive Formulation - The Core Factor

Zomatira palokha ndiye chodziwikiratu cha reusability. Njira zinayi zopangira zimathandizira kugwira ntchito mobwerezabwereza.

1. Kupititsa patsogolo mphamvu zogwirizanitsa ndi kachulukidwe ka crosslink

Gwiritsirani ntchito silikoni chingamu cha digiri yapamwamba ya polymerization ndikuwonjezera malo olumikizirana kuti musinthe zomatira kukhala zotanuka. Izi zimalepheretsa kung'ambika kapena zomatira kusuntha mobwerezabwereza ndikuchepetsa kudzitaya kwa guluu wosanjikiza. Zomatira zolumikizidwa bwino zimasenda bwino m'malo mogawanika mkati.

2. Njira yotsika ya silicone yosamuka

Gwiritsani ntchito njira yochiritsira yowonjezera yopangidwa ndi platinamu ndikuchotsani bwino zinthu zomwe zimakhala zolemera kwambiri. Izi zimalepheretsa exudation yaing'ono-molecule silikoni mafuta kuipitsa zomatira pamwamba ndi kupewa mosalekeza mamasukidwe akayendedwe attenuation. Zomatira zosamuka pang'onopang'ono zimasunga mawonekedwe awo apachiyambi pamayendedwe ambiri.

3. Mapangidwe a Microphase kuti agwirizanenso

Onjezani utomoni wa silikoni wa MQ kapena pangani netiweki yolowera polima kuti mupange gawo lolimba-gawo lofewa la microphase :

• Magawo olimba - amapereka mgwirizano kuti mupewe kusamutsidwa kwa guluu wotsalira

• Zigawo zofewa - zimapereka tackiness

Mbali ya mamasukidwe akayendedwe akhoza anachira pambuyo kupukuta fumbi pamwamba. Izi 'zosinthika' ndizoyenera kwa mapulogalamu omwe amafunikira kusintha kangapo pakuphatikiza.

4. Madzi osambitsa recoverable zomatira kusinthidwa

Zomatira zikafika poipitsidwa ndi fumbi, zomatira za silikoni zosinthidwazi zimatha kutsukidwa ndi madzi aukhondo kapena zosungunulira zofewa, ndikubwezeretsanso 90% ya zomangira zake zoyambirira zitayanika. Izi ndizofunikira kwambiri pazantchito zoyeretsa kapena zamagetsi pomwe kuyipitsa sikungapeweke.

Limbitsani Mphamvu Yoyimitsa Pakati pa PTFE Substrate ndi Zomatira Zosanjikiza

PTFE imakhala ndi mphamvu zotsika kwambiri (18-20 dynes/cm), zomwe zimapangitsa kusamutsa zomatira mosavuta - zomatira zonse zimakweza kumbuyo - popanda chithandizo chodzipereka.

1. Kutsegula kwa gawo lapansi

Pangani mankhwala etching ndi sodium-naphthalene complex kapena mankhwala a plasma pa PTFE fiberglass nsalu kuti adziwitse magulu a polar monga C=O ndi -OH, kulola kugwirizanitsa mankhwala kapena kulumikiza mwamphamvu makina pakati pa zomatira ndi gawo lapansi. Izi zimalepheretsa zomatira kuti zisavute chothandizira pakuchotsa.

2. Kupaka kwapadera koyambira

Ikani choyambira chokhazikika musanayambe zokutira zomatira kuti mupange mlatho wamankhwala pakati pa PTFE ndi zomatira za silikoni, kuchotseratu kulephera kwa anangula. The primer imagwira ntchito ngati ulalo wa mamolekyu, wolumikizana ndi PTFE yolumikizidwa ndi silicone PSA.

Aokai PTFE imagwiritsa ntchito makina oyambira omwe amaonetsetsa kuti zomatira ziro zisinthidwe kumalo ochiritsira ngakhale pambuyo pa 10+ kuchotsa kuzungulira.

Kumbuyo (Release Surface) Kukhathamiritsa Kwamankhwala

Kumbuyo kwa PTFE mwachilengedwe kumapereka magwiridwe antchito, komabe kupindika mobwerezabwereza ndi kumasuka kumawononga zomatira chifukwa cha mikangano ndi kung'ambika.

1. Kupititsa patsogolo kumasulidwa kwa ntchito kumbuyo zokutira

Ikani chowonjezera cha high-crosslink-density fluorosilicone kapena silikoni yotulutsa wosanjikiza pa PTFE kumbuyo. Imasunga mphamvu yosasunthika yosasunthika pansi pa kutentha kwakukulu ndi kupsinjika kwa nthawi yayitali, kuteteza kukoka kwa ulusi ndi kuwonongeka kwa zomatira musanagwiritsenso ntchito.

2. Chojambula kapena chopangidwa pang'ono kumbuyo

Chepetsani malo enieni olumikizana pakati pa wosanjikiza wakumbuyo ndi zomatira, kutsitsa mphamvu yowononga nthawi yomweyo pa guluu pakusenda. Pamwambapa pamakhala mawonekedwe ang'onoang'ono amachepetsa 'kutsetsereka' komwe kumatha kung'amba zomatira.

Malangizo Ogwira Ntchito ndi Kusamalira

Ngakhale tepi yopangidwa bwino kwambiri idzalephera msanga ngati itasamalidwa bwino. Zochita zoyenerera zimawonjezera kugwiritsidwanso ntchito kwambiri.

1. Yogwira kuyeretsa zomatira pamwamba

Kuchuluka kwa viscosity kumayamba chifukwa cha kuipitsidwa kwafumbi pamwamba. Pukutani pamwamba pang'onopang'ono mbali imodzi ndi nsalu yopanda fumbi yoviikidwa m'madzi oyera kapena mowa wopanda madzi, ndiyeno muwume mpweya mwachibadwa kapena ndi mphepo yozizira - kupirira kudzachira modabwitsa. Kuyeretsa nthawi zonse pakati pa zomwe zimagwiritsidwa ntchito ndi njira imodzi yothandiza kwambiri yokonza.

2. Pewani kuwonongeka pansi pazikhalidwe zantchito

• Pendani pang'onopang'ono pamakona ang'onoang'ono (pafupi ndi 180 °) kuti muchepetse chiopsezo cha kulephera kwa mgwirizano.

• Osagwiritsa ntchito pamwamba oveteredwa kutentha - zomatira adzakalamba ndi kuumitsa, kutaya reusability.

• Yeretsani zomatira musanayambe - madontho amafuta amawononga msanga zomatira ndipo sangathe kuchotsedwa kwathunthu.

3. Kuthetsa thovu mpweya pa lamination

Fumbi limakonda kuwunjikana m'mphepete mwa nthibwibwibwi ndikuyambitsa kupsinjika komweko, kumathandizira kukalamba komatira. Kugwiritsa ntchito bwino kopanda thovu (pogwiritsa ntchito squeegee kapena roller) kumakulitsa moyo wogwiritsanso ntchito tepiyo.

Chidule - Miyezo Inayi ya Kupititsa patsogolo Kukonzanso

Aokai PTFE imapanga matepi a PTFE okometsedwa kuti azimatira mobwerezabwereza. Makalasi athu ochapira madzi amatha kuchira> 90% tack pambuyo poyeretsa, ndipo makina athu oyambira amatsimikizira kusamutsa kwa zero. Lumikizanani nafe kuti mupeze zomwe mungakonde komanso data yoyesa kuzungulira.

Chikalata chaukadaulochi chikuperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Material Technology Co., Ltd.

Ngati mukufuna kuphunzira mwatsatanetsatane, momwe mungagwiritsire ntchito ndi njira zothetsera makonda athu onse, kuphatikiza nsalu za PTFE zotentha kwambiri, matepi omatira otentha kwambiri a PTFE, malamba a PTFE mauna otumizira, malamba osakanikirana opanda msoko, nsalu yotchinga mbali imodzi ya PTFE, nsalu yotchinga ndi magalasi apamwamba a PTFE, kulumikizana ndi nsalu yotchinga kutentha kwambiri kudzera pamakanema omwe ali pansipa:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira filosofi yautumiki ya ukatswiri ndi kukhulupirika, odzipereka kukupatsirani mayankho ophatikizika amodzi ndi kasitomala woganizira!
