Silicone kashe cyangwa ibifatika nigicuruzwa gikomeye, cyoroshye gishobora gukoreshwa mubikorwa byinshi bitandukanye. Nubwo kashe ya silicone idakomeye nka kashe imwe cyangwa ibifatika, kashe ya silicone ikomeza guhinduka cyane, nubwo imaze gukama neza cyangwayakize. Ikimenyetso cya Silicone kirashobora kandi kwihanganira ubushyuhe bwo hejuru cyane, bigatuma biba byiza mubisabwa guhura nubushyuhe bwinshi, nko kuri gaze ya moteri.
Ikirangantego cya silicone gikize kigaragaza uburyo bwiza bwo guhangana nikirere, kurwanya gusaza, kurwanya UV, kurwanya ozone, kurwanya ubushyuhe bwo hejuru no hasi, kurwanya ihindagurika, kurwanya ubushuhe, hamwe n’ibikoresho bitangiza amazi; kubwibyo, ibyifuzo byayo ni byinshi cyane. Mu myaka ya za 90, ubusanzwe yakoreshwaga mu guhuza no gufunga mu nganda z’ibirahure, bityo bakunze kwita "gufatira ibirahuri."

Ikimenyetso cya silicone gisanzwe gishingiye kuri 107 (hydroxy-terminated polydimethylsiloxane), kandi igizwe nibikoresho nka polimeri ifite uburemere buke bwa polymers, plasitike, ibyuzuza, ibikoresho bihuza, ibikoresho bihuza, catalizator, nibindi. amavuta, amavuta yera, nibindi bikoreshwa mubisanzwe byuzuza harimo karubone ya calcium ya nano ikora, karubone ya calcium iremereye, karubone ya ultrafine calcium, silika yumye, nibindi bikoresho.
Ikimenyetso cya silicone kiza muburyo butandukanye.
Ukurikije ubwoko bwububiko, bugabanijwemo: ibice bibiri (byinshi) nibice bimwe.
Ibice bibiri (byinshi) bisobanura ko kashe ya silicone igabanijwemo amatsinda abiri (cyangwa arenze abiri) ibice A na B, igice kimwe cyonyine ntigishobora gukira, ariko nyuma yibice bibiri (cyangwa birenze bibiri) bivanze, bazabikora kubyara umusaruro uhuza gukiza reaction kugirango ukore elastomers.
Uruvange rugomba gukorwa ako kanya mbere yo kurukoresha, rutuma ubu bwoko bwa silicone kashe ariko buroroshye gukoresha.
Ikimenyetso cya silicone gishobora kandi kuza nkigicuruzwa kimwe, nta kuvanga bisabwa. Ubwoko bumwe bwa silicone kashe imwe yitwaUbushyuhe bwo mucyumba Vulcanizing(RTV). Ubu buryo bwa kashe butangira gukira bikimara guhura n'umwuka - cyangwa, cyane cyane, ubuhehere buri mu kirere. Kubwibyo, birakenewe ko ukora vuba mugihe ukoresheje kashe ya RTV silicone.
Ikimenyetso kimwe cya silicone kashe irashobora kugabanywamo hafi: ubwoko bwa deacidification, ubwoko bwa alcoolisation, ubwoko bwa deketoxime, ubwoko bwa deacetone, ubwoko bwa deamidation, ubwoko bwa dehydroxylamine, nibindi ukurikije ibintu bitandukanye bihuza (cyangwa molekile nto zakozwe mugihe cyo gukiza) zikoreshwa. Muri byo, ubwoko bwa deacidification, ubwoko bwinzoga nubwoko bwa deketoxime bikoreshwa cyane kumasoko.
Ubwoko bwa Deacidification ni methyl triacetoxysilane (cyangwa Ethyl triacetoxysilane, propyl triacetoxysilane, nibindi) nkumuti uhuza, utanga aside acike mugihe cyo gukira, bakunze kwita "acide acide". Ibyiza byayo ni: imbaraga nziza no gukorera mu mucyo, kwihuta gukiza. Ibibi ni: kurakaza acide acetike, kwangirika kwibyuma.
Ubwoko bwa Dealcoolisation ni methyl trimethoxysilane (cyangwa vinyl trimethoxysilane, nibindi) nkumukozi uhuza, uburyo bwo gukiza butanga methanol, bakunze kwita "kole yo mu bwoko bwa alcool". Ibyiza byayo ni: kurengera ibidukikije, kutangirika. Ibibi: gutinda gukira buhoro, kubika ubuzima burakennye gato.
Ubwoko bwa Deketo ni methyl tributyl ketone oxime silane (cyangwa vinyl tributyl ketone oxime silane, nibindi) nkumukozi uhuza, utanga okisime ya butanone mugihe cyo gukira, bakunze kwita "ubwoko bwa glime". Ibyiza byayo ni: nta mpumuro nini cyane, kwizirika neza kubikoresho bitandukanye. Ibibi: kwangirika k'umuringa.
Ukurikije imikoreshereze yibicuruzwa bigabanijwemo: kashe yubatswe, imiterere yikirere idashobora guhangana nikirere, urugi nidirishya rifunga, gufunga kashe, kashe yumuriro, kashe ya anti-mildew, kashe yubushyuhe bwo hejuru.
Ukurikije ibara ryibicuruzwa kumanota: ibara risanzwe ryirabura, farashi yera, ibonerana, ifeza yumukara wubwoko 4, andi mabara dushobora gukora dukurikije ibyifuzo byabakiriya toning.
Hariho ubundi buryo butandukanye, tekinoroji yateye imbere muburyo bwa silicone kashe nayo. Ubwoko bumwe, bwitwaigitutu cyoroshyekashe ya silicone, ifite ubwitonzi buhoraho kandi yubahiriza igitutu nkana - mu yandi magambo, nubwo izahora “yumiye,” ntishobora gukomera niba hari ikintu cyogeje cyangwa gihagaritse kukirwanya. Ubundi bwoko bwitwaUV or imirasire yakizesilicone kashe, kandi ikoresha urumuri ultraviolet kugirango ikize kashe. Hanyuma,thermosetkashe ya silicone isaba guhura nubushyuhe kugirango ikire.
Ikimenyetso cya silicone gishobora gukoreshwa muburyo butandukanye. Ubu bwoko bwa kashe bukoreshwa kenshi mumodoka hamwe nibisabwa bifitanye isano, nk'imfashanyo yo gufunga moteri, hamwe na gaze. Kuberako ihindagurika ryiza, kashe nayo ihitamo neza kubyo akunda cyangwa ubukorikori.
