Ihame ry'imikorere ya hydroxypropyl methylcellulose muri mortier

Hydroxypropyl methylcellulose (HPMC)ni polymer ishongesha amazi ikoreshwa cyane mu nganda z'ubwubatsi, cyane cyane mu byuma bikozwe muri sima, ibyakozwe muri gypsum na kole y'amatafari. Nk'inyongeramusaruro ya morti, HPMC ishobora kunoza imikorere y'ubwubatsi, kunoza ubushobozi bwo gukora, gufatana, kubika amazi no kudacika kw'urukuta, bityo yongera ubwiza bwa morti.

1. Imiterere y'ibanze ya HPMC

HPMC iboneka ahanini binyuze mu guhindura cellulose mu buryo bwa etherification, kandi ifite ubushobozi bwo gushonga neza mu mazi, gukomera, gukora filime, gusya neza no kudahungabana. Imiterere yayo y'ingenzi ikubiyemo:

Gushonga kw'amazi: Ashobora gushonga mu mazi akonje cyangwa ashyushye kugira ngo habeho umuti ubonerana cyangwa ubonerana.
Ingaruka zo gushonga: Bishobora kongera cyane ubukana bw'umuti no kugaragaza ingaruka nziza zo gushonga iyo ufite ubunini buke.
Kubika amazi: HPMC ishobora kwinjiza amazi no kubyimba, kandi ikagira uruhare mu kubika amazi muri mortiwo kugira ngo hirindwe ko amazi atakara vuba cyane.
Imiterere ya rheological: Ifite thixotropy nziza, ifasha kunoza imikorere y'ubwubatsi bwa mortiweri.

2. Uruhare rw'ingenzi rwa HPMC mu gukurura ibintu

Uruhare rwa HPMC muri mortilator rugaragarira ahanini muri ibi bikurikira:

2.1 Kunoza uburyo amazi abikwa muri morti

Mu gihe cyo kubaka sima, iyo amazi ashizemo umwuka vuba cyane cyangwa akanyongerwa cyane n'ishingiro, bizatuma amazi adahagije kandi agire ingaruka ku iterambere ry'imbaraga. HPMC ikora imiterere imwe y'urushundura muri sima binyuze mu kuba ifite ubushobozi bwo gukurura amazi no kuyakura, igafunga ubushuhe, ikagabanya igihombo cy'amazi, bityo ikagabanya igihe cyo gufungura sima no kunoza uburyo bwo kuyihindura.

2.2 Ingaruka zo gukomera, kunoza ubushobozi bwo gukora bwa sima

HPMC ifite ubushobozi bwo gukurura ibintu, ishobora kongera ubukana bwa morti, bigatuma morti igira plasticity nziza, kandi ikarinda morti kuva mu byiciro, gutandukanya ibintu no kuva amazi. Muri icyo gihe, gukurura ibintu bikwiye bishobora kunoza imiterere ya morti, bigatuma byoroha kuyishyira no kuyipima mu gihe cy'ubwubatsi, kandi bikanoza imikorere y'ubwubatsi.

2.3 Kongera uburyo bwo gufatana no kunoza uburyo bwo gufatana kwa morti

Mu bikorwa nka kole y'amatafari, sima y'amabuye n'isima ya plaster, imbaraga zo guhuza sima ni ingenzi cyane. HPMC ikora filime ya polymer imwe hagati y'ishingiro n'igitambaro binyuze mu gukora filime, ibyo bikanoza imbaraga zo guhuza sima n'igice cy'ubutaka, bityo bikagabanya ibyago byo gusenyuka no kugwa kwa sima.

2.4 Kunoza imikorere y'ubwubatsi no kugabanya kugwa

Ku bijyanye no kubaka ubuso buhagaze (nk'ubusitani bwo ku rukuta cyangwa kubaka kole y'amatafari), sima ishobora kugwa cyangwa kunyerera bitewe n'uburemere bwayo. HPMC yongera umuvuduko w'umusaruro no kurwanya kugwa kw'isima, kugira ngo sima ibashe gufata neza ubuso bw'ifatizo mu gihe cyo kubaka buhagaze, bityo bikanoza ubusugire bw'ubwubatsi.

2.5 Kongera ubushobozi bwo kurwanya uduce duto no kongera igihe gihagije

Ishitingi rikunze kwangirika bitewe no kugabanuka mu gihe cyo gukomera, bigira ingaruka ku bwiza bw'umushinga. HPMC ishobora guhindura imbaraga z'imbere za sima no kugabanya umuvuduko wo kugabanuka. Muri icyo gihe, binyuze mu kunoza ubushobozi bwa sima, igira ubushobozi bwo guhangana n'impinduka mu gihe cy'impinduka z'ubushyuhe cyangwa stress zo hanze, bityo igakomeza kuramba.

2.6 Ingaruka ku gihe cyo gushyiraho sima

HPMC igira ingaruka ku gihe cyo gushyiraho sima binyuze mu guhindura umuvuduko w'amazi ya sima. Ingano ikwiye ya HPMC ishobora kongera igihe cyo kubaka sima no gutanga igihe gihagije cyo kuyitunganya mu gihe cyo kuyitunganya, ariko kuyikoresha cyane bishobora kongera igihe cyo kuyishyiraho no kugira ingaruka ku iterambere ry'umushinga, bityo ingano igomba kugenzurwa neza.

3. Ingaruka z'igipimo cya HPMC ku mikorere ya mortilage

Igipimo cya HPMC muri mortilage muri rusange kiba kiri hasi, akenshi kiri hagati ya 0.1% na 0.5%. Igipimo cyihariye giterwa n'ubwoko bwa mortilage n'ibisabwa mu bwubatsi.:

Igipimo gito (≤0.1%): Gishobora kongera uburyo amazi abikwamo kandi kikongera ubushobozi bwo gukora bwa mortiweri, ariko ingaruka zo kubyibuha ni nkeya.

Igipimo kiringaniye (0.1% ~ 0.3%): Binongera cyane ubushobozi bwo kubika amazi, gufatana no kurwanya kugwa kw'amazi mu cyuma kandi bikongera imikorere myiza mu bwubatsi.

Igipimo kinini (≥0.3%): Bizongera cyane ubukana bwa mortiweri, ariko bishobora kugira ingaruka ku kunyura kw'amazi, bikongera igihe cyo gushyiraho, kandi ntibibe byiza ku bwubatsi.

Nk'inyongeramusaruro y'ingenzi kuri mortier,HPMCIfite uruhare runini mu kunoza uburyo amazi abikwamo, kunoza imikorere y’ubwubatsi, kongera uburyo bwo gufatana no kudafatana kw’iminyururu. Kongeramo HPMC mu buryo bukwiye bishobora kunoza cyane imikorere ya sima no kunoza ubwiza bw’umushinga. Muri icyo gihe, igipimo kigomba kugenzurwa kugira ngo hirindwe ingaruka mbi ku gihe cyo gushyiraho no kunyura kw’amazi mu bwubatsi. Mu gihe kizaza, hamwe n’iterambere rihoraho ry’inganda z’ubwubatsi, amahirwe yo gukoresha HPMC mu bikoresho bishya by’ubwubatsi bishya azarushaho kuba manini.
