PTFE Nsalu Yotentha Kwambiri: Chifukwa Chake Imapindika Mosakwanira ndi Zomwe Mungachite

Ngati mudapindapo chidutswa cha PTFE- TACHIMATA fiberglass nsalu yotchinga kwambiri, inu mwina anaona woyera crease mzere kuonekera nthawi yomweyo. Pindaninso pamalo omwewo, ndipo nsaluyo imatha kung'ambika.

Ichi si chilema - ndi khalidwe lachibadwa la zinthu. Nsalu yotentha kwambiri ya PTFE imapambana kukana kutentha, mankhwala, ndi kumamatira, koma flex resistance (kubwereza mobwerezabwereza kupirira) ndi katundu wake wofooka kwambiri.

Aokai PTFE yayesa moyo wosinthika kudutsa makulidwe ambiri ndi makulidwe. Nkhaniyi ikufotokoza chifukwa chake nsaluyo imapindika bwino, ikufanizira ndi zipangizo zina, ndipo imapereka njira zogwirira ntchito zochepetsera malire.

Chifukwa chiyani PTFE Nsalu Imakhala Ndi Zovuta Zosamvana za Flex?

Choyambitsa chake ndi gawo lapansi la fiberglass , osati zokutira za PTFE.

1. Fiberglass - yamphamvu koma yolimba

Ulusi wagalasi uli ndi mphamvu zolimba kwambiri koma zotalika kwambiri panthawi yopuma (nthawi zambiri 2-4%). Akapindika mobwerezabwereza, ulusi wina umakhala wotopa komanso wosweka. Kamodzi ulusi wochepa umasweka, kupsinjika maganizo kumangoganizira zotsalazo, zomwe zimayambitsa kufalitsa mofulumira - nsaluyo imalira mosavuta.

2. PTFE zokutira - chotchinga chochepa

PTFE wosanjikiza mafuta ulusi ulusi, kuchepetsa mikangano mkati ndi kuwongolera pang'ono pliability. Komabe, sichingathe kuthetsa kuphulika kwa galasi. Zimangochedwetsa kuphulika kwa ulusi ndi malire ang'onoang'ono.

Kodi Zimasiyana Bwanji ndi Zida Zina?

Chotengera chofunikira: PTFE-yokutidwa ndi fiberglass imakhala kumapeto kwapakati mpaka kumunsi pakati pa nsalu zotentha kwambiri zolimba kukana. Ndikwabwino kuposa magalasi opanda kanthu koma oyipa kwambiri kuposa filimu yoyera ya PTFE.

Zinthu Zofunika Zomwe Zimakhudza Kukaniza kwa Flex

1. Makulidwe - chinthu chofunikira kwambiri

Lamulo la chala chachikulu: Nsalu zopyapyala zimasinthasintha bwino. Pamapulogalamu omwe amafunikira kupindika mobwerezabwereza, tchulani giredi lathinnest lomwe limakwaniritsa zosowa zanu zina (mphamvu, kutentha).

2. Kumanga zokhotakhota

• Kuluka kwa Satin - zoyandama zazitali zimalola ulusi kuti usasunthike pang'ono, ndikugawa kupsinjika kopindika. Moyo wofewa bwino kuposa kuluka wamba.

• Zoluka zokhotakhota - nsonga zokhotakhota zotsekera ulusi; kupsinjika kumakhazikika pamphambano. Zoyipa kwambiri kukana flex.

3. Kutentha kwa ntchito

Pakutentha kwambiri (200-260 ° C), zokutira za PTFE zimafewetsa, ndipo mphamvu zamakina a fiberglass zimachepa. Izi zimawonjezera kukana kutopa kwa flex. Ngati ntchito yanu ikukhudza kutentha kwambiri komanso kupindika pafupipafupi, yembekezerani moyo waufupi.

4. Kupinda kozungulira

Utali wokulirapo = moyo wautali. Kuwotcha (radius <1mm) kumapanga mikwingwirima yakufa ndikusweka nthawi yomweyo. Kwa ma roller owongolera, gwiritsani ntchito mainchesi akulu kwambiri. Monga chiwongolero chaukali, chowongolera chocheperako chocheperako ndi 10-20x makulidwe a nsalu.

Internal test data (Aokai PTFE) : Pakuti 0.13mm satin yokhotakhota nsalu, kupinda mandrel 10mm akwaniritsa 500-800 m'zinthu pamaso akulimbana looneka. Pa mandrel 5mm, mikombero idatsika mpaka 100-150. Pa 2mm mandrel (lakuthwa crease), kulephera kunachitika mkati mwa 20 kuzungulira.

Malangizo Ogwiritsa Ntchito

Ngati zida zanu zimafuna kupindika pafupipafupi - monga:

• Malamba oyendetsa ma welder apamwamba kwambiri

• Malamba omangika omwe amangiriza timadontho tating'onoting'ono

• Kumangirira malamba okhotakhota okhala ndi matembenuzidwe akuthwa

Muli ndi njira zitatu:

1. Njira 1 - Konzani PTFE kusankha nsalu mkati mwa malire ake

• Sankhani magiredi owonda (0.08mm mpaka 0.13mm) kuposa olemetsa

• Kukonda zoluka za satini kuposa zoluka wamba

• Funsani MIT flex test data kuchokera kwa ogulitsa anu (ASTM D2176 kapena ofanana)

• Kupanga kwa radiyo yayikulu yopindika pamakina a makina

• Landirani nsalu za PTFE ngati zodyedwa - konzekerani zosintha nthawi ndi nthawi (miyezi ingapo iliyonse kutengera kuchuluka kwa kuzungulira)

2. Njira 2 - Sinthani ku filimu yolimba ya PTFE

Filimu yoyera ya PTFE (skived) ili ndi kukana kwapadera. Komabe, ilibe mphamvu yolimbitsa magalasi a fiberglass, chifukwa chake imakhala ndi mphamvu zocheperako komanso imang'ambika mosavuta. Ndizoyenera kugwiritsa ntchito zopepuka, zopindika pang'ono.

3. Njira 3 - Gwiritsani ntchito nsalu za aramid kapena organic fiber

Aramid (mwachitsanzo, Nomex) kapena nsalu ya PPS yokutidwa ndi PTFE imapereka moyo wabwino wosinthika kuposa nsalu ya PTFE yopangidwa ndi galasi. Kugulitsa: kuchepetsa kutentha kosalekeza (nthawi zambiri ≤200 ° C) ndi zinthu zosiyanasiyana zapamtunda. Pazogwiritsa ntchito pansi pa 200 ° C zopindika molemera, lingalirani izi.

Aokai PTFE imapanga nsalu ya aramid yokhala ndi PTFE ikafunsidwa. Lumikizanani nafe kuti mudziwe kutentha ndi kusinthasintha.

Mwachidule - Dziwani malire, Pangani Moyenera

Nsalu ya PTFE yotentha kwambiri imayima bwino motsutsana ndi kupsinjika, kutentha kwakukulu (260 ° C), ndi kuukira kwa mankhwala. Koma kusasunthika kwake kosasunthika ndizovuta zenizeni. Iwo sangakhoze kupirira lakuthwa mobwerezabwereza kupindana ngati malamba mphira kapena koyera PTFE filimu.

Gwiritsani ntchito pomwe kupindika kumakhala kofatsa kapena kosachitika pafupipafupi.
Kumene kukuthwa kapena kupindika pafupipafupi sikungalephereke, chepetsani, gwiritsani ntchito nsalu za satin, onjezerani ulusi wopindika, kapena sinthani zinthu.

Aokai PTFE imapereka chidziwitso chosinthika pamakalasi athu onse a nsalu. Titha kukuthandizani kusankha makulidwe oyenera ndikuluka pazofuna zanu zopindika.

Zaukadaulo zoperekedwa ndi Malingaliro a kampani Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mudziwe zambiri komanso njira zothetsera PTFE nsalu zotentha kwambiri, tepi, lamba wa mauna, lamba wosakanikirana, ndi zina zambiri:

• Bambo Guo: +86 18944819998

• Bambo Liu: + 86 13705266308

Timatsatira ukatswiri ndi kukhulupirika, kupereka njira imodzi ayimitsa mafakitale.
