Ifu ya silikoni cyangwa kole ni ikintu gikomeye kandi cyoroshye gishobora gukoreshwa mu buryo butandukanye. Nubwo ifu ya silikoni idakomeye nk'ifu ya silikoni cyangwa kole zimwe na zimwe, ifu ya silikoni ikomeza koroha cyane, nubwo yamaze kuma cyangwayakizeSilicone sealant ishobora kwihanganira ubushyuhe bwinshi cyane, bigatuma iba nziza cyane ku bikoresho bihura n'ubushyuhe bwinshi, nko kuri gasket za moteri.
Isefa ya silikoni ivuwe ifite ubushobozi bwo kurwanya ikirere neza, kurwanya gusaza, kurwanya imirasire ya UV, kurwanya ozone, kurwanya ubushyuhe bwinshi n'ubukonje, kurwanya guhindagura, kurwanya ubushuhe, no kwirinda amazi; bityo, ikoreshwa ryayo ni rinini cyane. Mu myaka ya 1990, yakoreshwaga mu gufatanya no gufunga mu nganda z'ibirahuri, bityo izwi cyane nka "kode y'ibirahuri."

Ifoto y'ibumoso: Ipakiye ingoma ya silicone sealant
Ibikoresho byo gufunga bya silicone bikunze gukoreshwa kuri 107 (hydroxy-terminated polydimethylsiloxane), kandi bigizwe n'ibikoresho nka polymeri zifite uburemere bwa molekile nyinshi, plasticizers, fillers, cross-linking agents, coupling agents, catalysts, nibindi. Ibikoresho bikunze gukoreshwa birimo amavuta ya silicone, amavuta yera, nibindi. Ibikoresho bikunze gukoreshwa birimo nano-activated calcium carbonate, heavy calcium carbonate, ultrafine calcium carbonate, fumed silica, nibindi bikoresho.
Ibifunga bya silikoni biza mu buryo butandukanye.
Dukurikije ubwoko bw'ububiko, bugabanyijemo ibice bibiri (byinshi) n'igice kimwe.
Ibice bibiri (byinshi) bivuze ko silicone sealant igabanyijemo amatsinda abiri (cyangwa arenga abiri) ibice A na B, igice kimwe cyonyine ntigishobora gukora curating, ariko nyuma yuko ibice bibiri (cyangwa arenga bibiri) bivanze, bizakora cross-linking curing reaction igahinduka elastomers.
Uruvange rugomba gukorwa ako kanya mbere yo kurukoresha, ibyo bigatuma ubwo bwoko bwa silicone sealant bugorana kubukoresha.
Ifu ya silikoni ishobora no kuza ari ikintu kimwe, nta kuvanga bisaba. Ubwoko bumwe bwa silikoni ifu ya silikoni ikoreshwa mu buryo bumwe bwitwaUbushyuhe bw'icyumba butera imvururu(RTV). Ubu bwoko bw'icyuma gifunga butangira gukira bukimara gushyirwa mu kirere - cyangwa, mu by'ukuri, ubushuhe buri mu kirere. Kubwibyo, ni ngombwa ko ukora vuba iyo ukoresha icyuma gifunga cya RTV silicone.
Isefa ya silicone ifite ibice bimwe ishobora kugabanywamo ibice bikurikira: ubwoko bwa deasideification, ubwoko bwa dealcoholization, ubwoko bwa deketoxime, ubwoko bwa deacetone, ubwoko bwa deamideation, ubwoko bwa dehydroxylamine, nibindi, hakurikijwe ibintu bitandukanye bihuza (cyangwa molekile nto zikorwa mu gihe cyo gukaraba) bikoreshwa. Muri byo, ubwoko bwa deasideification, ubwoko bwa dealcoholization n'ubwoko bwa deketoxime ni byo bikoreshwa cyane ku isoko.
Ubwoko bwa deasidi ni methyl triacetoxysilane (cyangwa ethyl triacetoxysilane, propyl triacetoxysilane, nibindi) nk'ikintu gihuza, gitanga aside asetiki mu gihe cyo kuyitunganya, izwi cyane nka "acide glue". Ibyiza byayo ni: gukomera no gukorera mu mucyo, kwihuta mu kuyitunganya. Ingaruka mbi ni: impumuro y'aside asetiki ikarishye, kwangirika kw'ibyuma.
Ubwoko bwa Dealcoholization ni methyl trimethoxysilane (cyangwa vinyl trimethoxysilane, nibindi) nk'ikintu gihuza, uburyo bwo kuyitunganya bukora methanol, izwi cyane nka "alcohol-type glue". Ibyiza byayo ni: kurengera ibidukikije, kutiyongerera ubukana. Ingaruka mbi: umuvuduko wo kuyitunganya ugenda buhoro, igihe cyo kuyibika ni gito gato.
Ubwoko bwa Deketo oxime ni methyl tributyl ketone oxime silane (cyangwa vinyl tributyl ketone oxime silane, nibindi) nk'ikintu gihuza, gitanga butanone oxime mu gihe cyo gushonga, izwi cyane nka "oxime type glue". Ibyiza byayo ni: nta mpumuro nyinshi cyane, gufata neza ibikoresho bitandukanye. Ingaruka mbi: kwangirika kw'umuringa.
Dukurikije ikoreshwa ry'ibicuruzwa bigabanyijemo: ikintu gifunga imiterere, ikintu gifunga kidahura n'ikirere, ikintu gifunga inzugi n'amadirishya, ikintu gifunga, ikintu gifunga kidashya, ikintu gifunga kidapfa, ikintu gifunga ubushyuhe bwinshi.
Dukurikije ibara ry'ibicuruzwa, reba ingingo zikurikira: ibara risanzwe ry'umukara, umweru wa porcelain, ubonerana, imvi y'ifeza ubwoko 4, andi mabara dushobora gukoresha dukurikije ibyo abakiriya bakeneye.
Hariho n'ubundi bwoko butandukanye bw'icyuma gifunga silicone giteye imbere mu ikoranabuhanga. Ubwoko bumwe bwitwaihangana n'umuvudukosilicone sealant, ifite ubushobozi bwo gufata neza kandi ifata neza ikoresheje ingufu nke - mu yandi magambo, nubwo ihora "ifata neza," ntabwo ifata neza niba ikintu kiyifashe cyangwa kiyihagazeho. Urundi bwoko rwitwaUV or imirasire yavuweumuti ufunga silicone, kandi ukoresha urumuri rwa ultraviolet mu kuvura umuti ufunga. Amaherezo,thermosetisilicone sealant isaba ko ihura n'ubushyuhe kugira ngo ikire.
Ifu ya silikoni ishobora gukoreshwa mu buryo butandukanye. Ubu bwoko bwa fu ya silikoni bukunze gukoreshwa mu modoka no mu bindi bifitanye isano, nko gufasha mu gufunga moteri, haba hari cyangwa hatarimo gasket. Kubera ko irushaho koroha, fu ya silikoni ni amahitamo meza ku bintu byinshi byo kwidagadura cyangwa ubukorikori.
