Nubwo isahani ya silicone hamwe na plaque ya reberi bifite ibintu bimwe na bimwe byoroshye kandi bifunga kashe, hari itandukaniro rikomeye mumikorere yabyo, ahanini biva muburyo butandukanye bwimiti nibikoresho fatizo.
Dore urufunguzo rwingenzi rwo kugereranya:
Kurwanya Ubushyuhe: Amabati ya Silicone: Biraramba cyane. Uru rupapuro rugumana uburebure - igihe kirekire mu bushyuhe bwagutse kuva kuri - 60 kugeza kuri dogere +230, hamwe no kwihanganira igihe gito - bigera kuri dogere 250 cyangwa na dogere 300. Ibi bituma biba byiza cyane - ibidukikije byubushyuhe nkitanura, amasahani yo gutekamo, ibikoresho bifunze ubushyuhe, amakariso yubushyuhe bwumuriro, hamwe nubushyuhe bwa elegitoronike. Amabati ya Rubber: Ntarengwa mubikorwa. Ubushyuhe bwihariye buterwa n'ubwoko bwa reberi: Rubber Kamere: -50 dogere +70 dogere (itesha agaciro ubushyuhe bwinshi kandi igacika intege kubushyuhe buke). Styrene Butadiene Rubber (SBR): -40 dogere +100 dogere. Nitrile Rubber (NBR): -30 dogere kugeza +120 dogere (kurwanya amavuta meza). Ethylene Propylene Diene Monomer (EPDM) Rubber: -50 dogere kugeza +150 dogere (ikirere cyiza no kurwanya ozone). Fluororubber: -20 dogere kugeza kuri +200 dogere cyangwa irenga (ubushyuhe budasanzwe no kurwanya imiti, nubwo bihenze).
Imiti ihamye no gusaza:Amabati ya Silicone: Yerekana imbaraga zidasanzwe zirwanya ogisijeni, ozone, na ultraviolet. Bagaragaza gusaza kudasanzwe gusaza, bakomeza guhinduka badafite gukomera, guturika, cyangwa gutakaza imbaraga za elastique na nyuma yo kuyikoresha igihe kirekire, mubisanzwe bitanga ubuzima burebure budasanzwe. Uru rupapuro rwerekana kwihanganira imishwarara ya polar (nka alcool, ketone, na acide zimwe na zimwe), ariko ikagaragaza ko idashobora guhangana n’imishwarara itari - (urugero: hydrocarbone ya alifatique, hydrocarbone ya aromatique, peteroli - amavuta ashingiye) hamwe na aside ikomeye / alkalis, bishobora gutera kubyimba cyangwa kwangirika. Amabati ya reberi: Kurwanya gusaza biratandukanye muburyo bwibintu. Rubber naturel na styrene - butadiene reberi (SBR) yunvikana nimirasire ya ozone na UV, ikunda gucika no gusaza. EPDM na fluororubber byerekana ikirere cyiza. Itandukaniro rikomeye mukurwanya imiti: Nitrile Rubber: Amavuta adasanzwe - irwanya (peteroli - amavuta ashingiye, hydrocarbone ya alifatique). Fluororubber: Kurwanya imiti idasanzwe (irwanya amavuta, acide, alkalis, umusemburo). Rubber Kamere: Irwanya acide nkeya / alkalis ariko ntabwo ari amavuta / umusemburo. EPDM: Irwanya amazi, amavuta, acide nkeya / alkalis, hamwe nudukoko twa polar, ariko ntabwo ari amavuta cyangwa amashanyarazi ya hydrocarubone.
Kubijyanye no kurwanya imiti, ubwoko bwombi bufite intego zitandukanye kandi bugomba gutoranywa hashingiwe kubitangazamakuru byihariye.
Imiterere yumubiri nubukanishi: Amabati ya silicone: Imbaraga za mashini (imbaraga za tensile and amarira) muri rusange ziri munsi ya rubber nyinshi. Mugihe herekana ibintu byoroshye, imikorere yabo ihoraho yoguhindura imikorere ntishobora guhura na reberi yo hejuru - (cyane cyane mugihe kirekire - ubushyuhe bwo kugabanuka). Bagaragaza imbaraga zo gukira neza kandi bagakomeza guhinduka neza mubushyuhe buke. Impapuro za reberi: Mubisanzwe zigaragaza imbaraga za mashini (cyane cyane imbaraga zo kurira no kurira). Imikorere ihoraho yoguhindura imikorere iratandukanye kubwoko no kuyikora, hamwe na reberi zimwe (urugero, EPDM) ikora neza. Kwihangana gukira muri rusange birashimishije. Ubushyuhe buke - biterwa nubwoko bwibintu (urugero, reberi karemano ikora neza mubushyuhe buke mugihe reberi ya nitrile ikomera mubihe bikonje).
Gukwirakwiza amashanyarazi:Amabati ya Silicone: Gutunga ibintu byiza byamashanyarazi byamashanyarazi bifite imbaraga nyinshi kandi birwanya imbaraga za dielectric, bikomeza umutekano muke mubushuhe bwinshi nubushyuhe. Byakoreshejwe cyane mubikoresho bya elegitoroniki n'amashanyarazi. Amabati ya reberi: Mubisanzwe byerekana amashanyarazi meza (cyane cyane EPDM), nubwo bidashobora guhura nubuziranenge hamwe na silicone. Rubber zimwe (urugero, reberi ikora irimo karubone yumukara) irashobora gushushanyirizwa hamwe cyangwa antistatike. Umwanzuro: Silicone yerekana ibyiza biri hejuru murwego rwo hejuru - kurangiza amashanyarazi (cyane cyane mubushyuhe bwo hejuru - nubushyuhe bwo hejuru -). Biocompatibilité na Non - Ubumara Kamere: Amabati ya Silicone: Yerekana ubudahangarwa bwa physiologique hamwe na biocompatibilité idasanzwe. Byoroshye gukorwa mubicuruzwa byujuje ibyiciro byibiribwa (FDA, LFGB) hamwe nubuvuzi (USP Class VI). Impumuro nziza na bagiteri - birwanya. Amabati ya reberi: Bitandukanye cyane muri biocompatibilité. Rubber karemano irashobora gutera allergie. Kugirango ugere ku byiciro byibiribwa cyangwa ubuvuzi bwa Grade, hasabwa gutoranya cyane ibikoresho fatizo ninyongeramusaruro (agent volcanizing agent, yihuta, anti - imiti ishaje, nibindi). Izi nyongeramusaruro zitwara ibyago byinshi byo kwimuka ugereranije na silicone, birashoboka kohereza impumuro nziza.
Umwuka wa gaze: Amabati ya silicone: Ibi bikoresho byerekana imyuka myinshi (urugero, umwuka) hamwe numwuka wamazi. Mugihe iyi mitungo ifite akamaro kubikorwa bimwe na bimwe (urugero, uduhumeka duhumeka, ibikoresho byubuhumekero), birashobora kwerekana ko ari bibi mugushiraho kashe. Amabati ya reberi: Mubisanzwe bifite gaze ya gaze cyane, cyane cyane butyl rubber, ikora nkibikoresho byiza byumuyaga.
Umwanzuro: Rubber muri rusange nibyiza mugukora kashe yumuyaga hamwe n’amazi. Ibiranga ubuso: Isahani ya silicone: Ubuso ni hydrophobique (amazi yanga), ntabwo byoroshye gukurikiza ibintu byinshi, byoroshye koza. Isahani ya reberi: Ibiranga ubuso biratandukanye bitewe n'ubwoko na formula, bimwe bishobora gukomera.
Igiciro: Isahani ya silicone: ihenze cyane. Igiciro cyibikoresho fatizo nigiciro cyumusaruro mubisanzwe birenze reberi isanzwe. Isahani ya reberi: ibiciro byinshi. Rubber naturel, SBR, NBR nibindi bikoreshwa cyane bya reberi biri hasi. Rubber idasanzwe (nka fluororubber, silicone rubber ubwayo) ibiciro ni byinshi.
Guhitamo ibikoresho byanyuma bigomba kugenwa no gusaba - ibisabwa byihariye birimo urwego rwubushyuhe bwo gukora, guhura nibitangazamakuru byimiti, umutwaro wubukanishi, ibiryo - urwego / ubuvuzi - guhuza amanota, gukenera umuyaga, hamwe nimbogamizi zingengo yimari.
Silicone na rubber byombi byerekana ibyiza bidasubirwaho mumirima yabo
