Udupira twa HPMC two gukingira ubushyuhe

Sima yo gushyushya ya HPMC yerekeza ku bikoresho by'ubwubatsi byahinduwe ahohydroxypropyl methylcellulose (HPMC)Yongerwaho nk'inyongera kuri mortilage ikingira ubushyuhe. HPMC ni eteri ya cellulose idafite ionic ifite ubushobozi bwo kubika amazi neza, gukomera, imikorere myiza mu bwubatsi no gufatanya. Yakoreshejwe cyane mu bwubatsi bwa mortilage, ifu ya putty, kole ya tile, mortilage ikingira ubushyuhe n'ahandi.

1. Uruhare rwa HPMC mu gukingira ubushyuhe

Intego nyamukuru yo kongeramo HPMC muri mortier irinda ubushyuhe ni ukunoza ubushobozi bwayo bwo gukora, kubika amazi, gufatana no kwirinda kugwa, kwemeza ko ikorwa neza, kandi ikagira imiterere myiza ya mekanike no kuramba nyuma yo gukomera. Imirimo yihariye ni iyi ikurikira:

1.1. Amazi agumana neza

HPMC ishobora kunoza cyane uburyo amazi abikwa muri sima, kwirinda gutakaza amazi vuba mu gihe cyo kubaka, gutuma sima irushaho kuba nziza, bityo ikongera imbaraga zo gufatanya n'imbaraga muri rusange za sima.

1.2. Kunoza imikorere y'ubwubatsi

Bitewe n'uburyo HPMC ikoresha amavuta meza kandi ikagira ubugari, sima yoroshye kuyishyiramo, yoroshye kuyishyiraho no kuyishyiraho, bigabanya uburyo bwo kuyisukamo no kuyijugunyamo ivu, kandi bikongera imikorere myiza mu bwubatsi.

1.3. Kongera ubushobozi bwo gufatana

HPMC ishobora kongera uburyo bwo gufatana hagati ya sima n'urwego rw'ibanze, kwirinda gushonga no gupfuka, no kunoza uburyo uru rwego rw'ubushyuhe muri rusange rudahinduka.

1.4. Irinde kugwa kw'amazi

Mu gihe cyo kubaka inkuta zihagaze, HPMC ishobora kunoza imikorere ya sima yo mu bwoko bwa mortier idacika, ku buryo iguma ihamye mu gihe cyo kubaka irangi rinini kandi ntiyoroshye kuyinyerera.

2. Imiterere y'imikorere ya sima ya HPMC insulation

Ifite uburemere kandi ikomeye: Ibice byoroheje nk'ibinini bya perlite na foam bikunze kongerwa muri morti. Iyo bikoreshejwe na HPMC, hashobora gukorwa urwego rworoshye kandi rufite imbaraga nyinshi rwo gukingira.

Ubushobozi buke bwo gutwara ubushyuhe: Ubusanzwe ubushobozi bwo gutwara ubushyuhe buri hagati ya 0.045 na 0.065 W/m·K, ibyo bikaba bibuza neza uburyo ubushyuhe butwara kandi bikanoza imikorere myiza y’ingufu z’inyubako.

Ubudahangarwa bwiza bw'ikirere: Mu gihe cy'ibikorwa bya HPMC, ubushobozi bwo kuramba no kudahangarwa kw'imashini irinda ubushyuhe burushaho kwiyongera, kandi ishobora kwihanganira imihindagurikire itandukanye y'ikirere.

Kurinda ibidukikije no kutabihumanya: HPMC ni ibikoresho by’icyatsi kibisi kandi birengera ibidukikije, bihura n’ibintu bidakomoka ku bimera nka sima n’umucanga, kandi ntibisohora ibintu byangiza.

3. Ahantu ho gusaba

Sima yo gushyushya ya HPMC ikoreshwa cyane mu bijyanye no gushyushya inkuta, gushyushya inkuta imbere, gushyushya ibisenge, nibindi mu nyubako zitandukanye. Ikwiriye cyane cyane mu mishinga yo kuvugurura izigama ingufu, inyubako ziri ahantu hakonje, inyubako rusange, nibindi, ibyo bikaba bigira ingaruka zikomeye ku kuzigama ingufu no kumererwa neza mu nyubako.

4. Ingamba zo kwirinda kubaka

Igipimo gikwiye: Sima ikoreshwa mu gushyushya ya HPMC igomba gutegurwa neza hakurikijwe ibisabwa mu gishushanyo n'imiterere y'inyubako, kandi ingano ya HPMC igomba kugenzurwa muri rusange hagati ya 0.2% na 0.5% (ku gipimo cy'ifu yumye).

Kangura neza: Mu gihe uvangavanga, ibikoresho byumye bigomba kuvangwa neza mbere na mbere, hanyuma amazi agashyirwamo akabyukwa neza, hanyuma ukongera ukangura nyuma yo guhagarara iminota mike.

Kugenzura ibidukikije by'ubwubatsi: Irinde kubaka ahantu hari ubushyuhe bwinshi cyangwa umuyaga mwinshi kugira ngo wirinde ko ubushuhe bwa sima buhinduka vuba cyane kandi bukagira ingaruka ku ngaruka.

Uburyo bwo gutunganya inkingi: Inkingi igomba kuba isukuye, idafite amavuta n'umukungugu urekuye, kandi itose iyo bibaye ngombwa kugira ngo ifatanye neza.

Kugenzura ubunini bw'inyubako: Ubunini bwa buri sima ntibugomba kuba bunini cyane, muri rusange bugenzurwa muri cm 1.5, kandi urwego rw'inyubako rugomba gukorwa mu byiciro kugira ngo hirindwe ko hacikamo uduce duto cyangwa ngo habeho ubucucike.

Utwuma two gukingira ubushyuhe bwa HPMC, nk'ibikoresho by'ubwubatsi bizigama ingufu bifite imikorere myiza, bihuza ubushyuhe, ubushyuhe butuma ibintu birushaho kuba byiza, bikungahaye ku bushyuhe, ubushyuhe butuma ibintu birushaho kuba byiza, kandi bikoreshwa cyane mu nyubako zigezweho zikoresha ikoranabuhanga rigezweho. Kongeramo HPMC ntibyongera imikorere myiza ya sima, ahubwo binashimangira ireme ry'ubwubatsi n'ubuhanga mu buhanga. Ni uburyo bw'ingenzi mu bya tekiniki bwo guteza imbere kubungabunga ingufu z'inyubako no kubaka neza. Mu gihe kizaza, hamwe n'iterambere ryihuse ry'inyubako zikoresha ikoranabuhanga rigezweho, sima ikoresha ikoranabuhanga rigezweho rizagira uruhare runini mu buryo bwo kuzigama ingufu z'inyubako.
