Mu gihe cyizuba nimbeho, nkuko ubuhehere bugereranije mukirere bugabanuka kandi itandukaniro ryubushyuhe hagati yigitondo na nimugoroba ryiyongera, ubuso bwibice bifatanye bifatanye nurukuta rwumwenda wikirahure hamwe nurukuta rwimyenda ya aluminiyumu bizagenda buhoro buhoro bisohoka kandi bihindurwe ahantu hatandukanye hubakwa. . Ndetse n'imiryango imwe n'imwe idirishya irashobora guhinduka hejuru yubuso hamwe no gufatana hamwe gufatana kumunsi umwe cyangwa muminsi mike yo gufunga. Tuyita phenomenon ya kashe ya kashe.
1. Gutobora kashe ni iki?
Igikorwa cyo gukiza igice kimwe cyubaka ikirere kitarinda silicone kashe gishingiye kumyuka yo mu kirere. Iyo umuvuduko wo gukiza wa kashe utinze, igihe gikenewe kubutaka buhagije bwo gukiza kizaba kirekire. Iyo ubuso bwa kashe butarakomera kugeza mubwimbitse buhagije, niba ubugari bwikimenyetso gifatika gihinduka kuburyo bugaragara (mubisanzwe bitewe no kwaguka kwubushyuhe no kugabanuka kwikibaho), ubuso bwikibaho kizagira ingaruka kandi ntiburinganire. Rimwe na rimwe, ni ibibyimba hagati yikintu cyose gifatika, rimwe na rimwe ni ikibyimba gikomeza, kandi rimwe na rimwe ni ihindagurika. Nyuma yo gukira kwanyuma, ubwo buso butaringaniye buringaniye byose birakomeye imbere (ntabwo ari ibibyimba bitagaragara), hamwe byitwa "gutereta".
Ibibyimba bifatanye na rukuta rwa aluminiyumu
Ibibyimba bifatanye neza byikirahure cyumwenda
Ibibyimba bifatanye kumuryango no kubaka idirishya
2. Gutegera gute?
Impamvu shingiro yibintu byo "gutereta" ni uko ibifata bigenda byimurwa kandi bigahinduka mugihe cyo gukira, ibyo bikaba ibisubizo byingaruka zuzuye zimpamvu nkumuvuduko wo gukiza wa kashe, ubunini bwikomatanya, ibikoresho nubunini bwikibaho, ibidukikije byubaka, nubwiza bwubwubatsi. Kugira ngo ukemure ikibazo cyo guterana neza, ni ngombwa kuvanaho ibintu bibi bitera ibibyimba. Ku mushinga runaka, muri rusange biragoye kugenzura intoki ubushyuhe bwibidukikije nubushuhe bwibidukikije, kandi ibikoresho hamwe nubunini, hamwe nigishushanyo mbonera gifatika, nacyo cyaragenwe. Kubwibyo, kugenzura bishobora kugerwaho gusa muburyo bwa kashe (ubushobozi bwo kwimura ibintu hamwe no gukiza umuvuduko) hamwe nubushyuhe bwibidukikije.
A. Ubushobozi bwo kugenda bwa kashe:
Ku mushinga wihariye wurukuta rwumushinga, bitewe nagaciro kagenwe kangana nubunini bwa plaque, coefficente yibikoresho byerekana umurongo, hamwe nubushyuhe bwumwaka bwurukuta rwumwenda, ubushobozi buke bwo kugenda bwa kashe burashobora kubarwa hashingiwe kubugari bwashyizweho. Iyo ingingo ifatanye, kashe ifite ubushobozi bwo kugenda cyane igomba gutoranywa kugirango ihuze ibisabwa byo guhindura ibintu.
B. Gukiza umuvuduko wa kashe:
Kugeza ubu, kashe ikoreshwa mu bwubatsi mu Bushinwa usanga ahanini itabogamye ya silicone idafite aho ibogamiye, ishobora kugabanywa mu buryo bwo gukiza okisime ndetse n’ubwoko bwo gukiza alkoxy ukurikije icyiciro cyo gukiza. Umuvuduko wo gukiza wa oxyde silicone yihuta irihuta kuruta iyitwa alkoxy silicone. Mubidukikije byubaka hamwe nubushyuhe buke (4-10 ℃), itandukaniro rinini ryubushyuhe (≥ 15 ℃), hamwe nubushuhe buke ugereranije (<50%), gukoresha imiti ya silicone silicone irashobora gukemura ibibazo byinshi "gutereta". Byihuta umuvuduko wo gukiza wa kashe, nubushobozi bwayo bwo kwihanganira ihinduka ryimiterere mugihe cyo gukira; Buhoro buhoro umuvuduko wo gukira nuburyo bunini bwo kugenda no guhindura ingingo, niko byoroha kubifatizo bifatanye.
C. Ubushyuhe nubushuhe bwibidukikije byubatswe:
Ikintu kimwe cyubaka ikirere kitarinda silicone kashe gishobora gukira gusa nukwitwara nubushyuhe bwo mu kirere, bityo ubushyuhe nubushuhe bwibidukikije byubaka bigira ingaruka runaka kumuvuduko wacyo wo gukira. Muri rusange, ubushyuhe bwo hejuru nubushuhe bivamo kwihuta no gukiza umuvuduko; Ubushyuhe buke nubushuhe butera gukira buhoro buhoro reaction, bigatuma byoroha kumutwe. Icyifuzo cyiza cyo kubaka ni: ubushyuhe bwibidukikije hagati ya 15 ℃ na 40 ℃, ubushuhe bugereranije> 50% RH, hamwe na kole ntibishobora gukoreshwa mugihe cyimvura cyangwa shelegi. Ukurikije ubunararibonye, iyo ubushyuhe bugereranije bwikirere buri hasi (ubuhehere bugera kuri 30% RH mugihe kirekire), cyangwa hari itandukaniro rinini ryubushyuhe hagati ya mugitondo na nimugoroba, ubushyuhe bwumunsi burashobora kuba hafi 20 ℃ (niba ikirere ni izuba, ubushyuhe bwibikoresho bya aluminiyumu byerekanwe nizuba birashobora kugera kuri 60-70 ℃), ariko ubushyuhe nijoro ni dogere selisiyusi nkeya, kubwibyo guterana urukuta rwumwenda rukomatanya ni rusange. Cyane cyane kurukuta rwa aluminiyumu ifite ibikoresho byo hejuru byo kwagura ibintu hamwe no guhindura ubushyuhe bukomeye.
D. Ibikoresho by'akanama:
Isahani ya aluminiyumu ni ikintu gisanzwe gifite coefficient yo hejuru yo kwagura ubushyuhe, kandi coefficente yayo yo kwaguka ikubye inshuro 2-3 iy'ikirahure. Kubwibyo, amasahani ya aluminiyumu angana afite ubwiyongere bukabije bwumuriro no kugabanuka kurenza ikirahure, kandi bikunda guhura nubushyuhe bwinshi nubushyuhe bitewe nimpinduka zubushyuhe butandukanye hagati yumunsi nijoro. Ninini yubunini bwa plaque ya aluminium, niko ihinduka ryinshi riterwa nubushyuhe butandukanye. Niyo mpamvu kandi kashe imwe ishobora guhura nigihe ikoreshejwe ahantu hubatswe, mugihe mubice bimwe byubaka, guturika ntibibaho. Impamvu imwe yabyo irashobora kuba itandukaniro mubunini bwurukuta rwumwenda hagati yububiko bubiri.
3. Nigute wakwirinda kashe ya kashe?
A. Hitamo kashe ifite umuvuduko ukabije wo gukira. Umuvuduko wo gukira ugenwa cyane cyane nuburyo buranga kashe ubwayo, hiyongereyeho ibidukikije. Birasabwa gukoresha ibicuruzwa by "uruganda rwumye vuba" cyangwa guhindura umuvuduko wo gukira ukundi kugirango ukoreshe ibidukikije kugirango ugabanye amahirwe yo guturika.
B. Guhitamo igihe cyubwubatsi: Niba ihindagurika rifitanye isano (deforme absolute / ubugari bwuzuye) bwingingo nini cyane kubera ubuhehere buke, itandukaniro ryubushyuhe, ingano ihuriweho, nibindi, kandi ntakibazo cyakoreshwa, kiracyabyimba, niki? bigomba gukorwa?
1) Ubwubatsi bugomba gukorwa vuba bishoboka muminsi yibicu, kuko itandukaniro ryubushyuhe hagati yumunsi nijoro ni rito kandi ihindagurika ryurugingo rufatika ni ruto, bigatuma ridakunda kubyimba.
)
3) Hitamo igihe gikwiye cyo gushiraho kashe.
C. Gukoresha ibikoresho bisobekeranye byorohereza urujya n'uruza kandi byihutisha gukira kwa kashe. .
D. Koresha urwego rwa kabiri rwo gufatira hamwe. Ubwa mbere, shyira hamwe ifatanye ifatanye, utegereze ko ikomera kandi ihinduka elastike muminsi 2-3, hanyuma ushyireho igipande cya kashe hejuru yacyo. Ubu buryo bushobora kwemeza ubwiza nuburanga bwubuso bufatanye.
Muri make, ibintu byo "gutereta" nyuma yo kubaka kashe ntabwo ari ikibazo cyiza cya kashe, ahubwo ni ihuriro ryibintu bitandukanye bitameze neza. Guhitamo neza ingamba zifatika zo gukumira ibyubaka birashobora kugabanya cyane amahirwe yo kubaho "guturika".
