PTFE Tape Adhesion vs Zazzabi: Yadda ake Ingantawa

Jiangsu Aokai Sabbin Kayayyakin, ƙwararriyar tushen masana'anta na tef ɗin zafi mai zafi na PTFE, yana ba ku bayanan ƙwararru.

PTFE (Teflon) high-zazzabi tef iya kullum za a iya amfani da ci gaba a cikin zafin jiki kewayon -196 ℃ zuwa 260 ℃ . A mafi yawan aikace-aikace, iyakar juriya na zafin tef an iyakance shi ta hanyar m Layer  maimakon PTFE substrate. Ayyukansa yana bin ƙa'idodin da ke da alaƙa da yanayin zafi:

Ayyukan mannewa yana raguwa yayin da zafin jiki ke ƙaruwa  Tare da ƙaruwar zafin jiki, mannen yana yin laushi a hankali, yana rarrafe har ma ya ragu, yana haifar da raguwar ƙarfin haɗin gwiwa. Macroscopically, wannan yana bayyana a matsayin digo na riƙe mannewa.

Ƙofar aiki da aka ƙayyade ta nau'in mannewa  daban-daban manne daban-daban suna da yanayin rashin gazawa daban-daban:

 

Don haɓaka lokacin riƙe zafin jiki mai girma , haɓakawa ana aiwatar da shi ne daga bangarori uku: ƙirar mannewa, aikin ƙasa, da tsarin haɗin kai.

1. M Layer: Haɓaka Rauni Link

·  Zaɓi tsarin mannewa mai juriya mai zafi mai zafi : Ba da fifikon mannen matsi na silicone don yanayin aiki mai zafi na dogon lokaci.

Fluorocarbon  gyara : Gyara silicone m tare da fluorocarbon mahadi don tada gilashin mika zafin jiki (Tg) zuwa 230 ℃. Bayan 48 hours na ci gaba da amfani a 260 ℃, da mannewa kudi har yanzu ya wuce 85%.

Gabatar  da hanyar sadarwa ta hanyar sadarwa : Gina hanyoyin sadarwa na nano-sikelin ƙetare don haɓaka ƙarfin haɗin kai da juriyar juriya na mannewa a yanayin zafi mai girma.

Ƙara  masu daidaitawar thermal : Haɗa phenol mai hanawa da sauran masu daidaitawar thermal a cikin dabara don hana lalatawar iskar oxygen da kyau a ƙarƙashin zafi mai zafi.

2. Layer Layer: Tada iyakar juriya na yawan zafin jiki

Nano  -filler gyara : Ƙara nano silica, boron nitride nanotubes da sauran nanoparticles cikin PTFE substrate don samar da jiki crosslinking maki. Za a iya ƙara yawan zafin jiki na zafi da 20-30 ℃, yayin da ake kiyaye sama da 90% na mannewa na farko a 260 ℃.

Jiyya  ta hanyar haɗin gwiwar kwayoyin halitta : Crosslink PTFE sarƙoƙi na kwayoyin don ɗaga ci gaba da zafin sabis har zuwa 300 ℃.

·  Fiber ƙarfafa : Ƙara 25% gilashin fiber ko carbon fiber don bunkasa creep juriya ta 300%, kunna ci gaba da amfani har zuwa 280 ℃.

3. Interface & Tsarin Tsarin: Haɓaka kwanciyar hankali

Jiyya  na ƙasa : Aiwatar da magani na plasma ko etching na sinadarai a saman PTFE don haɓaka roughness da aikin saman, ƙarfafa mannewar fuska da guje wa delamination a babban zafin jiki.

Ƙara  tsaka-tsaki mai shinge : Saka Layer polyimide (PI) keɓe tsakanin PTFE substrate da m don toshe shigar da mannewa da ƙaura a ƙarƙashin babban zafin jiki, inganta yanayin tsarin gaba ɗaya.

Haɓaka  tsarin haɗaɗɗiyar : Ɗauki tsari mai haɗaɗɗun nau'i-nau'i: PTFE shafi + ƙarfafa substrate + barga mai zafin jiki , don daidaita juriya na zafi da aikin m gabaɗaya.

·  Ajiye haɓakawar haɓakar thermal : Matsakaicin haɓakar faɗaɗa madaidaiciyar PTFE kusan sau 10 na ƙarfe.

Ajiye tazarar 0.15-0.3 mm  a cikin ƙirar tsari don sakin zafin zafi yadda ya kamata.
