Mu bihe by'impeshyi n'imbeho, uko ubushyuhe mu kirere bugabanuka kandi itandukaniro ry'ubushyuhe hagati ya mugitondo na nimugoroba rikiyongera, ubuso bw'imigozi y'urukuta rw'ibirahure n'inkuta z'urukuta rwa aluminiyumu bugenda buhinduka buhoro buhoro ahantu hatandukanye hubatswe. Ndetse n'imishinga imwe n'imwe y'inzugi n'amadirishya ishobora kugira ikibazo cyo guhinduka kw'ubuso no gusohoka kw'imigozi y'urukuta ku munsi umwe cyangwa mu minsi mike nyuma yo gufungwa. Tubyita ikintu cyo gufunga.
1. Gupfundika kw'ibice bifunga ni iki?
Uburyo bwo gukaraba kw'icyuma gifunga silicone gikingira ikirere kimwe bushingiye ku gukora hamwe n'ubushuhe mu kirere. Iyo umuvuduko wo gukaraba kw'icyuma gifunga ugenda buhoro, igihe gisabwa kugira ngo ubujyakuzimu buhagije bwo gukaraba hejuru buzaba burebure. Iyo ubuso bw'icyuma gifunga butarakomera kugeza ku burebure buhagije, niba ubugari bw'icyuma gifunga buhinduka cyane (ubusanzwe bitewe no kwaguka no guhindagurika kw'igice), ubuso bw'icyuma gifunga buzahinduka kandi butaringaniye. Hari igihe kiba ari agahu hagati y'icyuma cyose gifunga, rimwe na rimwe kiba ari agahu gahoraho, kandi rimwe na rimwe kiba ari ukugorama guhindagurika. Nyuma yo gukaraba kwa nyuma, utu duce dufunganye two hejuru tuba dukomeye imbere (atari utubuto tw'ubururu), hamwe twitwa "kubyimba".
Uruvange rw'umugozi w'urukuta rw'umwenda wa aluminiyumu rumeze nk'urukuta
Uruvange rw'umugozi w'urukuta rw'ikirahure rukozwe mu buryo bwa kole
Uruvange rw'umugozi w'urugi n'amadirishya ukozwe mu buryo bwa kole
2. Kubyimba bibaho gute?
Impamvu y'ibanze y'iyi "buji" ni uko kole igenda yimuka cyane mu gihe cyo kuyitunganya, ibi bikaba ari ingaruka z'ibintu byinshi nko kwihuta kw'icyuma gifunga, ingano y'icyuma gifunga, ibikoresho n'ingano y'icyuma, imiterere y'inyubako, n'ubwiza bw'inyubako. Kugira ngo ikibazo cyo kwihuta mu migozi y'icyuma gifunga, ni ngombwa gukuraho ibintu bibi bitera kwihuta. Ku mushinga runaka, muri rusange biragoye kugenzura ubushyuhe n'ubushuhe bw'ibidukikije, kandi ibikoresho n'ingano yacyo, ndetse n'imiterere y'icyuma gifunga, nabyo byaragenwe. Kubwibyo, kugenzura bishobora kugerwaho gusa binyuze mu bwoko bwa kole (ubushobozi bwo kwimuka n'umuvuduko wo kuyitunganya) n'impinduka z'ubushyuhe mu bidukikije.
A. Ubushobozi bwo kugenda bwa sealant:
Ku mushinga w’urukuta rw’amaridoro runaka, bitewe n’agaciro kadahinduka k’ingano y’amaridoro, igipimo cyo kwagura ibikoresho by’aho hantu, n’impinduka z’ubushyuhe ku mwaka ku rukuta rw’amaridoro, ubushobozi buke bwo kugenda bw’iridoro bushobora kubarwa hashingiwe ku bugari bw’iridoro. Iyo iridoro ari rito, hagomba gutoranywa iridoro rifite ubushobozi bwo kugenda cyane kugira ngo rihuze n’ibisabwa kugira ngo rihinduke.
B. Umuvuduko wo gufunga:
Kugeza ubu, agakoresho gafunga ibintu gakoreshwa mu kubaka mu Bushinwa gakoreshwa cyane cyane mu guhuza ingingo mu Bushinwa gafite ubwoko bwa silicone butagira aho bubogamiye, gashobora kugabanywamo ubwoko bwa oxime curing n'ubwoko bwa alkoxy curing hakurikijwe icyiciro cyo gufunga. Umuvuduko wo gufunga ibintu wa oxime silicone adhesion wihuta kurusha uwa alkoxy silicone adhesion. Mu bwubatsi bufite ubushyuhe buri hasi (4-10 ℃), itandukaniro rikomeye ry'ubushyuhe (≥ 15 ℃), n'ubushuhe buke (<50%), gukoresha oxime silicone adhesion bishobora gukemura ibibazo byinshi "biturika". Uko agakoresho gafunga ibintu byihuta, niko gashobora kwihanganira guhinduka kw'ingingo mu gihe cyo gufunga; Uko umuvuduko wo gufunga ugenda buhoro kandi uko igice kigenda kirushaho kugenda no guhinduka, niko byoroha ko igice gifunga ibintu kibyimba.
C. Ubushyuhe n'ubushuhe by'aho bubaka:
Imashini ifunga silicone irinda ikirere ishobora gusa gukiza iyo ihuye n'ubushuhe mu kirere, bityo ubushyuhe n'ubushuhe bw'aho ikorera bigira ingaruka ku muvuduko wayo wo gushya. Muri rusange, ubushyuhe bwinshi n'ubushuhe bitera kwihuta mu gusubiza no gushya; Ubushyuhe buke n'ubushuhe bitera kwihuta mu gusubiza, bigatuma umushongi w'icyuma ubyimba. Imiterere myiza y'inyubako isabwa ni iyi: ubushyuhe buri hagati ya 15 ℃ na 40 ℃, ubushuhe buri hagati ya 50% RH, na kole ntishobora gukoreshwa mu gihe cy'imvura cyangwa urubura. Hashingiwe ku bunararibonye, iyo ubushuhe bw'ikirere buri hasi (ubushuhe bugera kuri 30% RH igihe kirekire), cyangwa hari itandukaniro rinini ry'ubushyuhe hagati ya mugitondo na nimugoroba, ubushyuhe ku manywa bushobora kuba hafi 20 ℃ (niba ikirere ari izuba, ubushyuhe bw'ibikoresho bya aluminiyumu bihura n'izuba bushobora kugera kuri 60-70 ℃), ariko ubushyuhe nijoro ni dogere selisiyusi nke gusa, bityo gupfundika kw'imigozi y'urukuta ni ibintu bikunze kugaragara. Cyane cyane ku nkuta z'urukuta za aluminiyumu zifite imiterere miremire y'ibikoresho n'ubushyuhe bukabije.
D. Ibikoresho by'urupapuro:
Isahani ya aluminiyumu ni ibikoresho bisanzwe bifite ingano yo kwaguka k'ubushyuhe, kandi ingano yayo yo kwaguka k'umurongo ikubye inshuro 2-3 ugereranyije n'ikirahure. Kubwibyo, amasahani ya aluminiyumu angana afite ubushyuhe bwinshi n'ihindagurika ry'ingufu kurusha ikirahure, kandi akunze kugaragara ko ubushyuhe bwinshi bugenda buhinduka bitewe n'impinduka mu bushyuhe hagati y'amanywa n'ijoro. Uko ingano ya sahani ya aluminiyumu ari nini, niko ihinduka ry'ubushyuhe riterwa n'impinduka mu bushyuhe. Iyi niyo mpamvu kandi agakoresho kamwe gashobora kugaragara ko gafite ihindagurika iyo gakoreshejwe ahantu hamwe na hamwe ho kubaka, mu gihe mu mazu amwe n'amwe yo kubaka, ihindagurika ry'ubushyuhe ntiribaho. Impamvu imwe ishobora kuba itandukaniro mu bunini bw'amabati yo ku rukuta hagati y'amazu abiri yo kubaka.
3. Ni gute wakwirinda ko agakoresho gafunga ibintu gaturika?
A. Hitamo agakoresho gafunga ibintu gafite umuvuduko wo gushonga vuba. Umuvuduko wo gushonga uterwa ahanini n'imiterere y'agakoresho gafunga ibintu ubwabyo, hiyongereyeho n'ibintu bifitanye isano n'ibidukikije. Ni byiza gukoresha ibikoresho by'ikigo cyacu "by'igihe cy'imbeho by'umuvuduko wo gushonga" cyangwa guhindura umuvuduko wo gushonga ukwabyo kugira ngo ugabanye ibyago byo kubyimba.
B. Guhitamo igihe cyo kubaka: Niba imiterere y’ingingo (imiterere y’ingingo/ubugari bw’ingingo) ari nini cyane bitewe n’ubushuhe buke, itandukaniro ry’ubushyuhe, ingano y’ingingo, nibindi, kandi uko byagenda kose, igakomeza kubyimba, ni iki cyakorwa?
1) Kubaka bigomba gukorwa vuba bishoboka mu minsi y'ibicu, kuko itandukaniro ry'ubushyuhe hagati y'amanywa n'ijoro ari rito kandi imiterere y'igice gifatana ikaba nto, bigatuma kidakunze kubyimba.
2) Fata ingamba zikwiye zo gupfuka igicucu, nko gukoresha inzitiramibu mu gupfuka urwego rw'izuba, kugira ngo utwo duce tudahura n'izuba, ugabanye ubushyuhe bw'utwo duce, kandi ugabanye kwangirika kw'ingingo guterwa n'itandukaniro ry'ubushyuhe.
3) Hitamo igihe gikwiye cyo gushyiramo sealant.
C. Gukoresha ibikoresho byometseho icyuho byoroshya urujya n'uruza rw'umwuka kandi bikihutisha umuvuduko wo gufunga. (Rimwe na rimwe, kubera ko ifuro ari rinini cyane, ifuro rirakandagirwamo rigahinduka isura mu gihe cyo kubaka, ibyo bikaba byanatuma ribyimba).
D. Shyiraho urwego rwa kabiri rwa kole ku ngingo. Ubwa mbere, shyiramo kole ifite imiterere y'inyuma, tegereza ko ikomera kandi ihinduka irabagirana mu minsi 2-3, hanyuma ushyireho urwego rwa sealant ku buso bwayo. Ubu buryo bushobora kwemeza ko kole ifite imiterere myiza kandi iteye neza.
Muri make, ikibazo cyo "kwishimagura" nyuma yo gukora sealant si ikibazo cy’ubwiza bw’iyi sealant, ahubwo ni uruvange rw’ibintu bitandukanye bibi. Guhitamo neza sealant no gukumira ibikorwa byo kubaka bishobora kugabanya cyane ibyago byo "kwishimagura".
