1. Incamake yikirahure
Ikirahuri cyiziritse ni ubwoko bwikirahure kizigama ingufu cyakoreshejwe cyane mumazu yubucuruzi, amazu manini manini, amazu yo guturamo maremare nizindi nyubako.Ifite ubushyuhe bwiza cyane hamwe nubwiza bwamajwi kandi nibyiza kandi bifatika.Ikirahuri cyiziritse kigizwe nibice bibiri (cyangwa byinshi) byikirahure bihujwe nicyogajuru.Hariho ubwoko bubiri bwingenzi bwo gufunga: uburyo bwa strip nuburyo bwo guhuza kole.Kugeza ubu, kashe ebyiri muburyo bwo guhuza kole nuburyo bukoreshwa cyane.Imiterere ni nkuko bigaragara ku gishushanyo 1: ibice bibiri byikirahure bitandukanijwe nicyogajuru, kandi kashe ya butyl ikoreshwa mugushiraho icyogajuru nikirahure imbere.Uzuza imbere imbere ya spacer ukoresheje icyuma cya molekile, hanyuma ushireho icyuho cyakozwe hagati yikirahure cyikirahure no hanze yacyo hamwe na kashe ya kabiri.
Igikorwa cya kashe ya mbere ni ukubuza imyuka y'amazi cyangwa gaze ya inert kwinjira no gusohoka mu cyuho.Ikirangantego cya Butyl gikoreshwa muri rusange kubera ko umuvuduko woguhumeka wamazi nigipimo cyo kohereza gaze ya inert ya butyl kashe iri hasi cyane.Nyamara, butyl kashe ubwayo ifite imbaraga nke zo guhuza hamwe na elastique nkeya, kuburyo imiterere rusange igomba gushyirwaho hamwe na kashe ya kabiri kugirango ihuze amasahani yikirahure hamwe nicyogajuru.Iyo ikirahuri gikinguye kiri munsi yumutwaro, urwego rwa kashe rushobora gukomeza ingaruka nziza.Igihe kimwe, imiterere rusange ntabwo igira ingaruka.

2. Ubwoko bwa kashe ya kabiri yo kubika ibirahuri
Hariho ubwoko butatu bwingenzi bwa kashe ya kabiri yo kubika ibirahuri: polysulfide, polyurethane na silicone.Imbonerahamwe 1 irerekana bimwe mubiranga ubwoko butatu bwa kashe nyuma yo gukira neza.
Imbonerahamwe 1 Kugereranya imikorere iranga ubwoko butatu bwa kashe ya kabiri yo kubika ibirahuri
Ibyiza bya kashe ya polysulfide ni uko ifite umwuka wamazi muke hamwe nogukwirakwiza gaze ya argon mubushyuhe bwicyumba;ibibi byayo ni uko ifite umuvuduko mwinshi wo kwinjiza amazi.
Igipimo cyo kugarura modulus na elastique kigabanuka cyane uko ubushyuhe bwiyongera, kandi imyuka yo mu mazi nayo iba nini cyane iyo ubushyuhe buri hejuru.Byongeye kandi, kubera ubukana bwa UV budasaza, imirasire yigihe kirekire ya UV izatera kwangirika kwinkoni.
Ibyiza bya kashe ya polyurethane ni uko imyuka y’amazi hamwe na gaze ya gaz ya argon iba mike, kandi imyuka y’amazi nayo iba mike ugereranije iyo ubushyuhe buri hejuru;ibibi byayo nuko ifite ubukana bwa UV busaza.
Ikirangantego cya Silicone bivuga kashe hamwe na polysiloxane nkibikoresho nyamukuru, byitwa kandi sisitemu yubuhinzi bwa silicone.Urunigi rwa polymer rwerekana kashe ya silicone rugizwe ahanini na Si-O-Si, ihujwe no gukora imiyoboro imeze nka Si-O-Si skeleton mugihe cyo gukira.Ingufu za Si-O (444KJ / mol) ni ndende cyane, ntabwo ari nini cyane kuruta izindi mbaraga za polymer, ariko kandi nini kuruta ingufu za ultraviolet (399KJ / mol).Imiterere ya molekuline ya silicone ituma kashe ya silicone igira ubukana buhebuje bwo hejuru kandi buke, kurwanya ikirere no kurwanya gusaza kwa UV, ndetse no gufata amazi make.Ingaruka za kashe ya silicone iyo ikoreshejwe mugukingira ikirahure ni gaze ya gaze.
3. Guhitamo neza kashe ya kabiri yo kubika ibirahuri
Niba ubuso bufatanye bwa polysulfide, kole ya polyurethane hamwe nikirahure byerekanwa nurumuri rwizuba igihe kirekire, degumming izabaho, ibyo bigatuma igice cyinyuma cyikirahure cyikirahure cyikirahure cyikirahure cyikirahure kigwa cyangwa kashe ya kubika ikirahuri cyumwanya ushyigikiwe nikirahure cyumwenda kugirango binanirwe.Kubwibyo, ikidodo cya kabiri cyo gukingira ikirahuri cyurukuta rwihishwa rwikariso hamwe nurukuta rwihishwa rwikariso rugomba gukoresha silicone yubatswe, kandi ingano yimbere igomba kubarwa ukurikije JGJ102 "Ibisobanuro bya tekiniki byerekana ibirahuri byububiko";
Ikirangantego cya kabiri cyo gukingira ikirahuri cyingoboka yikirahure cyikirahure kigomba gukoresha kashe ya silicone;kuri kashe ya kabiri yikirahure yikirahure kinini kinini gifungura urukuta rwumwenda, birasabwa gukoresha insuline yikirahure silicone yubatswe.Ikirangantego cya kabiri cyikirahuri cyakingiwe inzugi, amadirishya hamwe nurukuta rusanzwe rufunguye-rukuta rwumwenda urashobora gukingirwa ikirahuri silicone kashe, polysulfide kashe cyangwa polyurethane.
Ukurikije ibyavuzwe haruguru, abayikoresha bagomba guhitamo ibicuruzwa bya kabiri bya kashe yo kubika ibirahuri ukurikije uburyo bwihariye bwikirahure.Hashingiwe ko ubuziranenge bwa kashe bwujuje ibyangombwa, mugihe cyose bwatoranijwe kandi bugakoreshwa neza, ikirahuri gishobora gukora hamwe nubuzima bwa serivisi bujuje ibisabwa.Ariko niba byatoranijwe nabi kandi bigakoreshwa, niyo kashe nziza ishobora kubyara ibirahuri byujuje ubuziranenge.
Mugihe duhitamo ikidodo cya kabiri, cyane cyane kashe ya silicone yubatswe, tugomba nanone gutekereza ko kashe ya silicone igomba kuba yujuje ibyangombwa bisabwa byikirahure cyiziritse, guhuza hamwe na kashe yambere ya kashe ya butyl, kandi imikorere yikimenyetso cya silicone igomba kuba yujuje ibisabwa y'ibipimo bifatika.Muri icyo gihe, ubuziranenge bwibicuruzwa bya kashe ya silicone, gukundwa kwabakora ibicuruzwa bya silicone, hamwe nubushobozi bwa serivise yubuhanga hamwe nurwego murwego rwose rwo kugurisha mbere, kugurisha, na nyuma yo kugurisha nabyo ni ibintu byingenzi abakoresha bakeneye gusuzuma.
Gukingira ibirahuri bifata igice gito cyibiciro byose byo gukora ibirahure, ariko bigira ingaruka zikomeye kumiterere nubuzima bwa serivisi yo kubika ibirahuri.Gukingira ibirahuri byubatswe bifitanye isano itaziguye nibibazo byumutekano wurukuta.Kugeza ubu, uko amarushanwa ku isoko rya kashe agenda arushaho gukaza umurego, bamwe mu bakora ibicuruzwa bifunga ibicuruzwa ntibatindiganya kwigomwa imikorere y’ibicuruzwa n’ubuziranenge iyo bagabanije ibiciro kugira ngo batsinde abakiriya ku giciro gito.Umubare utari muto wibicuruzwa byujuje ubuziranenge kandi bidahenze byiganjemo ibirahuri byerekanwe ku isoko.Niba umukoresha ahisemo atitonze, kugirango abike ikiguzi gito cya kashe, birashobora guteza umutekano muke cyangwa bigatera impanuka nziza, zishobora guteza igihombo kinini.
Siway iragusaba guhitamo ibicuruzwa byiza nibicuruzwa byiza;icyarimwe, tuzabagezaho ingaruka zitandukanye ziterwa no gukoresha ubuziranenge bwikirahure bwikirahure bwa kabiri hamwe no gukoresha nabi mugihe kizaza.
