Kasete ya PTFE irashobora guteza imbere guhuza (guhagarika) no kwimura mugihe cyo kubika igihe kirekire. Impamvu: PTFE firime ya elastique yibuka na silicone PSA kunyerera munsi yumuvuduko / ubushyuhe. Kwirinda: guhindagurika gahoro gahoro (hanze yimbere, irekuye imbere) mugihe cyo gukora, hiyongereyeho igipfundikizo cyo kurekura kuruhande rudafatanye. Ubike kuri -15 ° C kugeza 40 ° C, 30-70% RH, utambitse kumurongo, uzunguruka buri gihembwe. Ku manota manini yometseho, ongeramo impapuro zisohora hagati yuburyo.

Imyenda yubushyuhe bwo hejuru ya PTFE itanga inyungu esheshatu zingenzi nkumukandara wogucapisha: hejuru yinkoni (gusohora paste na wino irekura neza), 260 ° C irwanya ubushyuhe (gukama neza), guhagarara neza (<0.5% kuramba, kwiyandikisha neza), kutagira imiti (kurwanya paste yangirika), guterana hasi (gukora neza), no guhinduranya (ubunini, ibara, anti-static). Nibyiza byo gucapura ecran, gucapura digitale, hamwe no kohereza ubushyuhe.

Imyenda irwanya PTFE yubushyuhe bwo hejuru ikomatanya idafite inkoni, irwanya ubushyuhe (260 ° C), hamwe nubushakashatsi bwimiti ya PTFE isanzwe hamwe nibikorwa bihamye. Ibyingenzi byingenzi: gukora ibikoresho bya elegitoronike (lamination ya PCB, gutunganya ibice), kumurika PV module (birinda kwangirika kwa ESD kwangiza imirasire yizuba), ibiribwa no gutunganya imiti (ESD-umutekano wo gutekesha ibyuma), ibihingwa ngandurarugo (anti-ruswa, imyanda irwanya static), ninganda zikora imyenda / icapiro. Kurwanya ubuso mubisanzwe 10⁶ - 10⁹ Ω.

Kanda ya PTFE yubushyuhe bwo hejuru yabitswe muburyo bwa muzingo irashobora kubabazwa no gufatana hagati (guhagarika) no kwimura ibiti kuruhande rutari inkoni. Imizi itera: PTFE firime ya elastique yibuka na silicone PSA igenda munsi yumuvuduko nubushyuhe. Igisubizo: gahoro gahoro ihindagurika - ifatanye kumurongo winyuma, irekuye kumurongo wimbere - ukoresheje kugenzura gufunga-gufunga. Uzuza hamwe no gusohora, kubika neza (15-40 ° C, 30-70% RH), gushyira kuri horizontal, no kuzunguruka buri gihembwe.

PTFE yubushyuhe bwo hejuru yimyenda ya serivise ubuzima buratandukanye cyane kubisabwa. Imiti irwanya ruswa irashobora kumara imyaka 3+ (4x kurenza reberi). Ibiryo byo guteka ibiryo mumezi ashize hamwe no kwangirika gake. Imikandara ya convoyeur yinganda yambara kuva guterana. PV lamination (150 ° C, EVA ihuza) ifite ubuzima buciriritse. Porogaramu zikomeye zo guterana amagambo (abrasive disiki) zifite ubuzima buke. Ibintu byingenzi: kugenzura ubushyuhe (guma ≤260 ° C), irinde ibisebe bikarishye, gukora isuku buri gihe, no gusimburwa mugihe gikwiye cyangwa gihindutse umuhondo.

PTFE yubushyuhe bwo hejuru bukoreshwa muguhuza ibiryo bigomba kubahiriza imipaka yubushyuhe bukabije: ≤260 ° C kugirango ikoreshwe ubudahwema (nta gihe ntarengwa), 260-300 ° C muminota 30 gusa, na> 300 ° C birabujijwe. Kaseti ni iy'itumanaho ritaziguye gusa (tray liners, igifuniko cy'ubushyuhe), ntabwo ipfunyika ibiryo. Ntuzigere ukora udafite umutwaro wibiryo (gushyushya byumye). Simbuza niba byijimye, umuhondo, cyangwa wambaye.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) imara igihe kirekire iyo ibitswe munsi ya 260 ° C, kure yimigezi ikarishye, kandi igasukurwa nibikoresho byoroshye. Ibintu nyamukuru bigabanya ubuzima: kwangirika kwubushyuhe hejuru ya 260 ° C, guhungabana kwubushyuhe buturutse kubushyuhe bwihuse / gukonjesha, umunaniro wubukanishi uva kunama no guhagarika umutima, igitero cyimiti ituruka kumyuma ya alkali yashongeshejwe cyangwa okiside ikomeye, kwangirika kwabashitsi mubyuma mugihe cyo gukora isuku, hamwe na UV ikoreshwa hanze. Ubwiza bwo gutwikira hamwe na substrate nabyo bifite akamaro.

Imyenda yubushyuhe bwa PTFE ihagaze neza kugeza kuri 300 ° C, ariko mumuriro irabora kandi ikarekura imyuka yuburozi cyane: hydrogène fluoride (HF) (korora, pulmonary edema) na perfluoroisobutylene (PFIB) (idafite ibara, impumuro nziza, ~ 10x uburozi burenze fosgene, nta antidote). Nanone umwuka wa karubone, ibisigazwa bya PFOA, na dioxyde de tronc. Ibisumizi bisanzwe byumwotsi ntacyo bikora; koresha ibikoresho byo guhumeka wenyine (SCBA). Ibimenyetso birashobora gutinda.

Silicone yumuvuduko ukabije (PSA) kuri kaseti ya PTFE yubushyuhe bwo hejuru iratandukanye cyane mubikorwa byo gusaza cyane. Methylphenyl silicone PSA igumana> 85% imbaraga zishishwa nyuma yiminsi 250 ° C / 7, mugihe ubwoko bwa methyl busanzwe bugabanuka kugera kuri 50-70%. Sisitemu yongeyeho (hydrosilylation) itanga ihame ryiza kuruta peroxide-yakize. Kumurimo uhoraho 200 ° C +, hitamo inyongera-yakize-amanota menshi.

Amashanyarazi ya PTFE yerekana ubushyuhe (PSA) kaseti igomba gukora ubushyuhe mugihe ikomeje. Ongeraho ibyuzuza bitezimbere ubushyuhe bwumuriro ariko bikomeretsa gufatira. Impirimbanyi nziza ikoresha uduce duto duto (nka skeleton yuyobora) ivanze nuduce twiza (kugirango twuzuze icyuho), igumane ibyuzuye byuzuye hejuru yurwego rwa percolation. Irinde flake na fibre; Bica tack.
