Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) ni nziza nkibikoresho fatizo bikoreshwa mu kuyikora. Ibice bibiri bifite akamaro: PTFE resin / emulsion (coating) na substrate ya fiberglass (imbaraga). Umwanda muri kimwe - ioni yicyuma, polimeri-ifite uburemere buke bwa polimeri, ingero zingana zisigaye, cyangwa okiside ya alkali - irashobora gutera kunanirwa imburagihe: umuhondo, guturika, gutakaza inkoni, gusiba, cyangwa gusenyuka.
Aokai PTFE ikoresha ibikoresho fatizo byera cyane no kugenzura neza. Aka gatabo gasobanura uburyo ubuziranenge bugira ingaruka kuri buri rwego rwimpamvu n'impamvu bisaba gusaba porogaramu.
PTFE Ibikoresho Byera - Ni ubuhe butumwa buriho?
Umwanda usanzwe muri PTFE urimo:
Monomers idakorewe hamwe na polimeri-ifite uburemere buke
Abatangije basigaye kandi batatanye (urugero, PFOA)
Iyoni z'icyuma (icyuma, umuringa, sodium)
Imfashanyo yo gutunganya nibicuruzwa
Isuku yo hejuru ituma ibikoresho bitanga imikorere hafi yuburyo bwiza.
1. Gushyushya ubushyuhe hamwe nubushyuhe bwumuriro
Iyoni z'icyuma (icyuma, umuringa, sodium) zikora nk'isoko ikomeye ya PTFE yangirika . Muri serivisi y'igihe kirekire hejuru ya 260 ° C, ndetse no kwanduza ibyuma byihuta byihuta byangirika, bigatera kwinjirira imburagihe no guturika. PTFE ifite isuku nyinshi iranga ubushyuhe bwo hejuru bwo kubora, igakomeza kuba umweru, kandi irwanya umuhondo neza.
Polimeri ifite uburemere buke hamwe nibicuruzwa byamavuta byimukira hejuru yubushyuhe mugihe cyo hejuru yubushyuhe bwo hejuru, bikora imvura.
Ibintu byangiritse bidafite inkoni: Ubuso burahinduka kandi bukunda gukurikiza ibikoresho bitunganijwe (ibiryo, kaseti zifata).
Ibyago byo kwanduza: Mu biribwa-byo mu rwego rw’ubuvuzi no mu buvuzi, imvura yimutse irashobora kwanduza ibicuruzwa kandi bikananirwa kubahiriza isuku. Isuku nicyerekezo cyibanze kubiryo-bihuza imyenda ya PTFE.
Iyoni zanduye (cations cations, halogen ion) zikora nk'itwara ryumuriro, bigabanya cyane imbaraga zo guhangana nubunini bwa voltage. Kubisabwa cyane (urugero, amashanyarazi yerekana amashanyarazi), ibikoresho byibanze ni ngombwa. Imyenge iterwa n'umwanda irashobora kandi gutuma umuntu asohoka igice.
4. Kurwanya imiti no guhuzagurika
Umwanda ushonga usohoka iyo uhuye nibitangazamakuru bya shimi, bigasiga micro-pore imbere muri kote. Izi nenge zituma gaze yangirika hamwe namazi byinjira kandi bikangiza substrate ya fiberglass, bikabangamira imikorere ya bariyeri.
Fiberglass Substrate Yera - Ibintu bya Alkali
Fiberglass ntabwo ari dioxyde ya silicon. Ibigize imiti isobanura ubushyuhe, imbaraga za mashini, hamwe na PTFE.
1. Ibirimo bya okiside ya alkali - ikintu gikomeye
Ubwoko bwa Fiberglass |
Na₂O + K₂O Ibirimo |
Ibiranga |
E-ikirahure (alkali-yubusa) |
<0.8% |
Isuku ryinshi, amashanyarazi meza cyane, gutakaza imbaraga gahoro kubushyuhe bwinshi - bisanzwe kumyenda ya PTFE |
Ikirahuri giciriritse |
~ 12% |
Igiciro gito, kurwanya ubushyuhe buke, imbaraga zigabanuka cyane mubushyuhe bwinshi |
Ikirahure kinini |
> 15% |
Gutesha agaciro vuba ubushyuhe; alkali ion itera PTFE kubora |
Ku bushyuhe bwinshi, ioni ya alkali ivuye mu kirahure gifite isuku nke ntabwo igabanya umwenda ubwayo ahubwo inatera kwangirika kwifuniko rya PTFE , byihuta kunanirwa muri rusange. Byongeye kandi, ikirahuri giciriritse / kinini-alkali gikurura ubuhehere, bigatuma irwanya kugabanuka kugabanuka cyane.
2. Kuringaniza abakozi - ubundi umwanda
Ibikoresho bifatika (krahisi, PVA, amavuta) bikoreshwa mugihe cyo kuboha fiberglass kugirango urinde fibre. Niba bidakuweho burundu mbere yo gutwikira PTFE, ibinyabuzima bisigaye karubone, ibora, na gaze mugihe cyo gucumura kuri 400 ° C.
Inenge zo hejuru: Ibara ry'umuhondo, ibibara byirabura, ibisebe - ibicuruzwa binanirwa kugenzura isura.
Guhuza intege nke: Ibisigazwa bya karubone bihagarika imiti nu mubiri hagati ya PTFE na fiberglass, bigatera gusibanganya, kubyimba, no gukuramo mugihe cya serivisi.
3. Kurwanya umunaniro udasanzwe
Micro air bubbles hamwe na kirisiti yanduye imbere ya fiberglass filaments bigabanya imbaraga zingana za fibre imwe. Mugihe cyo kunama inshuro nyinshi, izo nenge zihinduka ingingo yibanda kumurongo, bigatera kuvunika fibre hakiri kare kandi bikagabanya cyane ubuzima bworoshye.
Ibikoresho bitanduye bitanga imikorere yibanze yimyenda yubushyuhe bwo hejuru:
PTFE ifite isuku nyinshi igena: ubushyuhe bwa serivisi ntarengwa (260 ° C +), igihe kirekire kidahagarara neza, amashanyarazi yizewe, hamwe no kubahiriza ibiryo.
Fiberglass yuzuye-alkali idafite isuku (E-ikirahure, Na₂O <0.8%) hiyongereyeho ingero zingana zo gukuraho: imbaraga zimbaraga zubushyuhe bwinshi, ituze ryikigereranyo, hamwe no gufatisha neza nta gusiba.
Isuku idahagije mumurongo uwo ariwo wose bizatera kunanirwa imburagihe - umuhondo, gusiba, gusenyuka, no gutakaza inkoni - cyane cyane mubihe bibi: ubushyuhe bwigihe kirekire, umuvuduko mwinshi, cyangwa ibisabwa byisuku bikabije.
Aokai PTFE itanga gusa isuku ryinshi rya PTFE (ion yo hasi yicyuma, oligomer yo hasi) hamwe nigitambara cya E-ikirahure cya fiberglass (idafite alkali, isukuye neza). Dutanga ibyemezo bifatika kandi turashobora gushyigikira ibiryo-byo murwego rwohejuru. Twandikire kugirango ubone ibisobanuro birambuye.
Ibiri hejuru byavuzwe na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.
Niba ushaka kumenya byinshi kubyerekeranye nibisobanuro birambuye, ibintu bisabwa hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya mashini ya PTFE, imikandara yimashini idahwitse, umwenda umwe wa PTFE, imikandara ya convoyeur irwanya ubushyuhe bwinshi hamwe nigitambara cyo hejuru cya fiberglass, nyamuneka twandikire:
Twama dushyigikiye filozofiya yumwuga nubunyangamugayo, kandi twiyemeje kuguha ibisubizo bimwe na serivisi zitekereje.
