PTFE Fabric Coating Uniformity: Zinthu 4 Zazikulu Zomwe Muyenera Kuzilamulira

Kupaka kosiyana kwa PTFE kumabweretsa mikwingwirima, mapini, chikasu, kapena kusagwira bwino ntchito kopanda ndodo. Pazogwiritsa ntchito monga malamba osindikizira kutentha, malamba onyamula katundu, ndi zomangira zotulutsa, kufanana kwa zokutira kumakhudza kwambiri mtundu wazinthu komanso moyo wantchito.

Nchiyani chimayambitsa kuyanika kosiyana? Yankho limakhudza magawo anayi: ❖ kuyanika mapangidwe, ❖ kuyanika & sintering, khalidwe gawo lapansi, ndi malo kupanga.

Aokai PTFE yakonza izi pakupanga masauzande ambiri. Nkhaniyi ikufotokoza chinthu chilichonse komanso momwe mungawalamulire kuti akhale apamwamba, yunifolomu Nsalu zokutira PTFE.

Kupanga Coating - Chomwe Chimayambitsa Kufanana

Zothandiza nsonga: Nthawi zonse kuyesa aliyense mtanda wa PTFE emulsion kwa tinthu kukula kugawa ndi mamasukidwe akayendedwe pamaso kupanga. Kusintha kwa 10% mu viscosity kungasinthe ❖ kuyanika ndi 5-8%.

Ubale pakati pa kukula kwa tinthu PTFE ndi ❖ kuyanika yunifolomu nthawi zambiri mopepuka. Ma emulsion okhala ndi D50 pansi pa 0.12 μm amayenda mosavuta, kumapangitsa kupanga mkanda wa m'mphepete (kutchingira kokulirapo m'mphepete) pakuyanika. Ma emulsions okhala ndi D50 pamwamba pa 0.4 μm amalowa mugalasi la fiberglass molakwika, zomwe zimapangitsa kuti pakhale porosity komanso kufooka kwa fiber. Kusiyanasiyana koyenera (0.18-0.22 μm) kumapereka malowedwe abwino komanso kupanga mafilimu osalala. Chinthu chinanso chofunika kwambiri ndi surfactant content - surfactant kwambiri amachititsa thovu pamene dip ❖ kuyanika, kupanga mpweya thovu kuphulika ndi kusiya mabokosi. Kuchepa kwa surfactant kumatsogolera ku tinthu tating'onoting'ono ndi 'maso a nsomba' pamapeto omaliza. Pakufanana kofanana, gwirani ntchito ndi ogulitsa emulsion m'modzi ndikufunsa ziphaso zamagulu zowonetsa D50, D90, ndi kuchuluka kwa surfactant.

Aokai PTFE amagwiritsa yekha PTFE emulsion ndi mwamphamvu ankalamulira tinthu kukula kugawa (D50 0.18-0.22 μm, D90 <0.35 μm). Izi zimatsimikizira kulowa kosasinthasintha komanso kutha kwa pamwamba pamtunda uliwonse wa nsalu.

Kupaka & Sintering Njira - Gawo Lachidule la Kufanana

1. Njira Yopaka Kufananiza

Kuchita bwino kwambiri pamakampani: Njira zophatikizira - zokutira zoviika + zokutira masamba - zovomerezeka kwambiri. Izi zimaphatikizira kunyowetsa kwapamwamba kwambiri kwa zokutira zoviika ndi kutsetsereka kwapamwamba kwa zokutira tsamba, kuwongolera mphamvu ya ulusi wa encapsulation ndi kulondola kwapamwamba.

2. Kuyanika & Sintering Zinthu

Njira yophatikizira ya dip + blade ndiyo muyezo wamakampani opanga nsalu zapamwamba za PTFE zotentha kwambiri. Ichi ndichifukwa chake: kuviika kokha kumatulutsa 'meniscus effect' - chophimbacho chimakhala chochuluka m'mphepete mwake komanso chochepa pakati chifukwa cha kugwedezeka kwa emulsion pamene nsalu ikutuluka mu kusamba. Kusiyanasiyana kwapakati mpaka pakati kumatha kukhala 15-20% ya makulidwe onse. Kuphimba kwa tsamba kokha, pamene kumapanga malo ophwanyika, kumavutika ndi kulowa mkati - PTFE imakhala pamwamba popanda kuyika bwino ulusi wa fiberglass, zomwe zimapangitsa kuti asawonongeke. The ophatikizana ndondomeko: kuviika kwa malowedwe, ndiye yomweyo kudutsa pansi pa tsamba dokotala kuchotsa owonjezera ndi mlingo pamwamba. Kuti mupeze zotsatira zabwino, kusiyana kwa tsamba kuyenera kukhazikitsidwa ku 120-150% ya makulidwe omaliza omwe amafunidwa, kuwerengera kuchepa pakuyanika. Kutentha kwa ng'anjo ya sintering ndikofunikanso - 10 ° C gradient kudutsa m'lifupi kungayambitse mikwingwirima yowonekera.

Ubwino wa Substrate & Pre-treatment - Maziko a Uniformity

Malangizo: Pazinthu zofananira kwambiri (mwachitsanzo, matepi osindikiza kutentha), gwiritsani ntchito nsalu ya satin yoluka fiberglass yokhala ndi kuyeretsa kutentha kuti muchotse zotsalira zonse musanakutire PTFE.

Malo Opangira - Chitsimikizo cha Kufanana Kwapamwamba

Zothandiza: M'nyengo yamvula kapena masiku omwe kumakhala chinyezi chambiri, lingalirani kuyendetsa chowotcha m'chipinda chounikira. Chinyezi pamwamba pa 70% chimawonjezera kuwonongeka kwa pinhole.

Chidule - Kuyika Zonse Pamodzi

Mwachidule , ❖ kuyanika kufanana kwa PTFE mkulu-kutentha nsalu zimadalira zinthu zinayi zolumikizidwa. Kupaka mapangidwe (kukula kwa tinthu, kukhuthala, zolimba) ndiye chifukwa chake. Njira yopaka ndi sintering - makamaka kugwiritsa ntchito dip + blade kuphatikiza - ndiye gawo lomaliza. Ubwino wa substrate ndi chithandizo chisanachitike chimapereka maziko. Malo opanga amatsimikizira kusasinthika.

Pamafunso ofunikira omwe amafunikira kufanana kwakukulu (mwachitsanzo, matepi osindikiza kutentha, zomangira zomata), dip + blade kuphatikiza njira ndiyo muyezo wagolide wamakampani. Yang'anirani gawo lililonse pafupipafupi, sungani chilengedwe kukhala chokhazikika, ndikuyesa ma emulsion omwe akubwera kuti agawidwe kagawo kakang'ono.

Mukufuna thandizo kuti mukwaniritse zofanana zokutira pansalu yanu ya PTFE? Aokai PTFE imapereka ntchito zokutira mwachizolowezi ndikukambirana kwadongosolo. Lumikizanani nafe ndi zomwe mukufuna komanso kuchuluka kwa kupanga.

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

Ngati mukufuna kudziwa zambiri zatsatanetsatane, zochitika zamagwiritsidwe ntchito, ndi mayankho makonda pazogulitsa zathu zonse, kuphatikiza nsalu za PTFE zotentha kwambiri, matepi a PTFE kutentha kwambiri, malamba a mauna a PTFE, malamba a makina osakanizira, nsalu za PTFE zambali imodzi, nsalu zosagwirizana ndi kutentha komanso kutentha kwambiri , chonde omasuka kulankhula nafe:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Potsatira mfundo zautumiki za ukatswiri ndi kukhulupirika, tadzipereka kupereka mayankho okhazikika ndi ntchito zoganizira makasitomala onse.
