Hydroxypropyl methylcellulose (HPMC) ninyongeramusaruro yingenzi mumashanyarazi ya kijyambere hamwe nubwubatsi bwimiti.Imiterere yimikorere myinshi itezimbere ibintu byose bifatika, bifasha kunoza imikorere, gufata amazi, gufatira hamwe nibikorwa rusange.
Inganda zubaka zikomeje gushakisha ibisubizo bishya kugirango tunoze imikorere nigihe kirekire cyibikoresho byubaka.Mu nyongeramusaruro zitandukanye zikoreshwa mu gutunganya imiti y’ubwubatsi, hydroxypropyl methylcellulose (HPMC) yakwegereye abantu kubera ibyiza byayo byinshi bifata amatafari hamwe n’imiti yubaka.HPMC ikomoka kuri selile ifite imitungo idasanzwe ishobora kugira ingaruka nziza kumikorere yifata no kuzamura ireme rusange ryimishinga yubwubatsi.Intego yiyi ngingo ni ugushakisha uruhare ninyungu za HPMC mu gufatisha amabati no kuvanga imiti yubaka, gusobanura imiterere yimiti, uburyo bwibikorwa nibyiza bitanga mubikorwa byubwubatsi.
1. Ibigize imiti nibiranga HPMC:
Hydroxypropyl methylcellulose (HPMC) ni igice cya sintetike ya polymer yimiti yahinduwe kuva selile.Ihindurwamo no kuvura selile hamwe na oxyde ya propylene na methyl chloride, ikabyara hamwe na hydroxypropyl hamwe na methyl insimburangingo (-OH na -CH3 matsinda) ifatanye numugongo wa selile.Urwego rwo gusimbuza (DS) rwamatsinda ya hydroxypropyl na methyl rugena imiterere ya HPMC, harimo ubukonje, gukomera, hamwe nubushyuhe bwumuriro.
HPMC ifite amazi meza cyane kandi ikora igisubizo kiboneye kandi kibonerana mugihe gikwirakwijwe mumazi.Nyamara, gukomera kwayo biterwa nubushyuhe, hamwe nubushyuhe bwo hejuru bushyigikira guseswa.Uyu mutungo utuma HPMC ikwiriye gukoreshwa muburyo bwo kubaka imiti aho sisitemu ishingiye kumazi yiganje.Byongeye kandi, HPMC itanga imyitwarire ya pseudoplastique kubisubizo, bivuze ko ububobere bwayo bugabanuka mugihe cyogosha, bityo bikorohereza kubishyira mubikorwa no kunoza imikorere yimikorere ifatika.
2. Uburyo bwibikorwa bya ceramic tile yometse:
Mubisobanuro bifatika, HPMC ikora imirimo itandukanye kubera imiterere yihariye yimiti nimiterere.Imwe mumikorere yingenzi ni ugukora nkibyimbye, kunoza guhuza no gukora neza.Mu kongera ububobere, HPMC ifasha kurinda minisiteri yometse kunyeganyega cyangwa kugwa, byemeza neza kandi bihuza hagati ya tile na substrate.
HPMC ikora kandi nk'igikoresho cyo kubika amazi, cyemerera ibifata kugumana ibinyabuzima bihagije mu gihe cyo gukira.Uyu mutungo ningirakamaro kugirango habeho neza neza ibikoresho bya sima mu gufatisha, guteza imbere imiyoboro ikomeye no kugabanya ibyago byo kugabanuka.Byongeye kandi, ubushobozi bwa HPMC bwo gufata amazi bifasha kongera igihe cyo gufungura, bigatuma umwanya uhagije wo gushyira tile no guhinduka mbere yo gushiraho.
HPMC ikora firime ihindagurika kandi ifatanye mugihe yumye, bityo igahindura imiterere ihuza imiterere ya tile.Firime ikora nk'ibifatika, biteza imbere guhuza ibice bifatanye, amabati na substrate.Kubaho kwa HPMC byongera imbaraga muri rusange imbaraga hamwe nigihe kirekire cyo kwishyiriraho tile, bikagabanya ubushobozi bwo gusiba cyangwa gusibanganya igihe.
3. Ingaruka ku miti yubaka imiti:
Usibye gufatisha amatafari, HPMC ikoreshwa cyane mubikorwa bitandukanye byubaka imiti, harimo minisiteri, plaster na grout.Imiterere yimikorere myinshi ituma iba inyongera yingirakamaro kugirango yongere imikorere nigihe kirekire cyibikoresho.Muri minisiteri, HPMC ikora nka moderi ihindura imvugo, igenzura imyitwarire yimikorere no guhuza imvange.Ibi bituma porogaramu imwe ikoreshwa neza kandi ikanoza imikorere, ikorohereza gushyira no kugabanya imyanda.
HPMC ifasha kunoza imiterere-yimiterere yibintu byo hasi hamwe nimbuto za SCR, bigatuma habaho neza, ndetse nubuso.Ubushobozi bwayo bwo gufata amazi burinda imvange gukama imburagihe, itera gukira neza kandi igabanya ubusembwa bwubuso nkibice cyangwa ibice.Mubyongeyeho, HPMC yongerera imbaraga hamwe no gufatira plaster na grout, bikavamo gukomera, kurushaho kurangira.
Imikoreshereze ya HPMC mu miti y’ubwubatsi ijyanye n’intego z’inganda zubaka.Mugutezimbere gutunganya no kugabanya imikoreshereze yibikoresho, HPMC igira uruhare mugukoresha neza no kugabanya imyanda.Byongeye kandi, uruhare rwayo mukuzamura igihe kirekire cyibikoresho byubaka bifasha kongera igihe cyinyubako, bityo bikagabanya gukenera gusanwa cyangwa gusimburwa kenshi.
Hydroxypropyl methylcellulose (HPMC) igira uruhare runini muguhuza amabati ya kijyambere no kuvanga imiti yubaka, itanga inyungu zitandukanye zifasha kunoza imikorere, gukora no kuramba.Imiterere yihariye ya chimique hamwe nibiranga ituma ikora nkibibyimbye, bigumana amazi hamwe na porotokoro ya adhesion muburyo bwo gufatira hamwe.Byongeye kandi, HPMC itezimbere imiterere yimiterere yubwubatsi bwimiti yubaka kugirango byoroherezwe gukoreshwa no kwemeza uburinganire bwibicuruzwa byarangiye.
Ikoreshwa rya HPMC mu nganda zubaka ryerekana akamaro karyo nk'inyongeramusaruro itandukanye izamura ireme kandi rirambye ry'ibikoresho byo kubaka.Mugihe ibikorwa byubwubatsi bikomeje kugenda bitera imbere, gukenera ibisubizo bishya kugirango tunoze imikorere kandi biramba bizatera ubushakashatsi niterambere ryiterambere rya HPMC.Mugukoresha ubushobozi bwa HPMC, inganda zubwubatsi zirashobora kubona iterambere mubikorwa byimikorere kandi bikagira uruhare mugutezimbere ibidukikije byubaka kandi birambye.
