Ubushyuhe & Viscosity Attenuation ya PTFE Hejuru-Ubushyuhe bwo hejuru

Jiangsu Aokai Ibikoresho bishya, ukora umwuga wo gukora kaseti ya PTFE yubushyuhe bwo hejuru, asobanura ihinduka ryimikorere ya kaseti ya PTFE nyuma yo gukoresha ifuru inshuro nyinshi. Kwiyongera kwubushyuhe bwubushyuhe no gufata viscosity ahanini biri mubice bifatanye , aho kuba PTFE. Imiterere ya molekulire ya PTFE substrate irahagaze neza kandi imyaka iri munsi ya 260 ° C. Ibinyuranyo, ubushyuhe bwo hejuru bufatika nka silicone bugenda busaza bwa termo-okiside mugihe cyo gushyuha inshuro nyinshi, amaherezo bikagena ubuzima bwumurimo wa kaseti ya PTFE.

1. Amategeko ya Attenuation yo Kurwanya Ubushyuhe

Ubushyuhe busanzwe bw'itanura (≤ 260 ° C) Ibiti bifata imyaka buhoro buhoro kandi buhoro buhoro, hamwe nubushyuhe bwizina bugabanuka uko umwaka utashye. Ubuzima bwigihe kirekire bwumurimo ni imyaka 1-3.

Ubushyuhe bukabije (260–300 ° C) Gusaza kwifata byihuta cyane, kandi ubuzima bwa serivisi buragabanuka cyane kuva mumyaka myinshi kugeza kumyumweru make.

Ubushyuhe bukabije (＞ 300 ° C) Ibifatika byoroshya, bikabora ndetse bikanabika karubone byihuse, bikaviramo gutakaza ubwiza bwihuse no gucika mugihe gito.

Gusiganwa ku magare inshuro nyinshi Gushyushya byihuse no gukonjesha bitera ingaruka ziterwa nubushyuhe bwumuriro, bigatera micro-delamination hagati yumuti na substrate, kandi byihutisha kunanirwa nubushyuhe.

2. Amategeko ya Attenuation yo gufata Viscosity

Kugabanuka gahoro mugihe gisanzwe cyakazi Mubipimo byubushyuhe bwagenwe, gufata ubukonje bigenda bigabanuka buhoro buhoro hamwe no kwiyongera kwizuba, kandi igiti gifatika kirakomera kandi kigashyirwa mugihe runaka.

Kwiyongera gukabije mu gihe cy'ubushyuhe bukabije no mu bihe bibi Iyo bimaze gushyuha cyangwa guhura n'ibitangazamakuru bivura imiti, imbaraga zo guhuza zishobora kugabanuka hejuru ya 50% nyuma yo gukonja.

Ingingo y'ingenzi yo kunanirwa imikorere Nubwo kaseti ikomeza kuba nziza mumiterere, imiterere yayo idafatika hamwe no gufata irashobora kunanirwa mbere, bisaba gusimburwa mugihe.

3. Ibintu by'ingenzi byihutisha gutesha agaciro imikorere

Ubwoko bwa Adhesive Silicone yumuvuduko ukabije wibikoresho biranga ubushyuhe bugera kuri 260 ° C, biruta kure cyane ibyatsi bya acrylic (120-150 ° C gusa).

Imiterere ya Substrate Imiterere ya Fiberglass-yongerewe imbaraga ya PTFE itanga ihame ryiza cyane kandi irwanya ubushyuhe bwumuriro, hamwe nubuzima bumara igihe kirekire kuruta kaseti ya firime ya PTFE.

Ibidukikije bikoreramo Ubuvanganzo mugihe cyo gukora ifuru, kimwe no guhura na solve cyangwa flux, bizongera kwangirika kumubiri na chimique.

Ubwiza bwibikoresho Kaseti yo mu rwego rwo hasi ikunze kuba yarabeshye irwanya ubushyuhe, gusaza vuba kandi birananirana nyuma yizunguruka nkeya.

4. Gukoresha Ibyifuzo byo Gutinda Kugabanuka

Kugenzura ubushyuhe bukabije Komeza ubushyuhe bwigihe kirekire burigihe bukora munsi ya 260 ° C kandi wirinde gukora ubushyuhe burenze.

Guhitamo icyitegererezo cyiza Hitamo icyuma cyiza cya silicone ishingiye kuri kaseti ya PTFE, ishobora kwihanganira inzinguzingo zirenga 500 muri SMT hamwe nibikorwa bisa.

Porogaramu isanzwe Sukura neza hejuru yubusabane hamwe na Ethanol yuzuye mbere yo kumurika kugirango urebe neza kandi bikwiranye.

Gutezimbere uburyo bwiza Kugabanya inshuro zidakenewe zumuriro kugirango ugabanye kwangirika kwubushyuhe bwumuriro.

Ububiko bukwiye Ubike kaseti idakoreshwa ahantu hafunze, hijimye, hakonje kandi humye kugirango wirinde gusaza imburagihe.

Gusimburwa ku gihe birasabwa gusimburwa ako kanya iyo bimaze gukonjeshwa, hejuru ya karubone, kurigata cyangwa gutakaza imikorere itari inkoni bibaye, kugirango umusaruro uhamye.

Ibirimo byavuzwe haruguru bitangwa na Jiangsu Aokai New Material Technology Co., Ltd.

Niba ukeneye ibipimo birambuye, ibyerekanwe hamwe nibisubizo byabigenewe kumurongo wibicuruzwa byuzuye harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya PTFE yubushyuhe bwo hejuru, imikandara ya fuser idafite ikidodo, umwenda umwe wa PTFE, imikandara ya convoyeur irwanya ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, nyamuneka twandikire:

Buri gihe dukurikiza filozofiya yumwuga nubunyangamugayo, kandi tukaguha ibisubizo byizewe byinganda imwe hamwe na serivisi zitaweho.
