Nk'ibikoresho by'ubwubatsi bikoreshwa cyane mu nganda z'ubwubatsi, sima ifite uruhare runini mu miterere no mu mikorere. Uburyo sima itembera neza ni kimwe mu bimenyetso by'ingenzi bigira ingaruka ku mikorere y'inyubako. Uburyo bwiza bwo kugenda neza bufasha mu koroshya imirimo y'ubwubatsi no mu bwiza bw'inyubako. Kugira ngo sima itembera neza kandi ikore neza, hakunze gukoreshwa inyongeramusaruro zitandukanye mu kuvugurura. Muri zo,hydroxypropyl methylcellulose (HPMC), nk'ikintu gikunze gukoreshwa cyane mu gushonga mu mazi, kigira uruhare runini mu gushonga.
Ibiranga HPMC: HPMC ni polymer ishongesha amazi ikozwe muri cellulose karemano yahinduwe na shimi. Ifite ubushobozi bwo gukuba neza, kubika ingano, kubika amazi n'ibindi. Ntishongesha mu mazi, ariko ishobora gukora umuti utose mu mazi, bityo ikunze gukoreshwa cyane mu bwubatsi, gusiga irangi, imiti n'ibindi. Iyo ikoreshejwe nk'inyongeramusaruro, HPMC ishobora kunoza neza uburyo irangi ritose ritemba, rigafata amazi n'imikorere yaryo.
Ingaruka za HPMC ku kunyura kwa mortical:
Ingaruka zo gushonga: HPMC ubwayo igira ingaruka zikomeye zo gushonga. Iyo yongewe kuri morti, ishobora kongera cyane ubukana bwa morti. Ingaruka zo gushonga biterwa n'uko molekile za HPMC zigira imiterere y'urusobe rw'amazi, zigafata amazi kandi zigakwira, zikongera ubukana bw'amazi. Iyi nzira ituma ubukana bw'urusobe buhinduka. Iyo HPMC iri muri morti iri hejuru, amazi azagenda neza ku rugero runaka, bityo ubukana bw'urusobe muri rusange buzagaragaza impinduka runaka.
Kunoza uburyo amazi abikwa: HPMC ishobora gukora agace gato muri mortiwo kugira ngo igabanye ubushyuhe bw'amazi no kunoza uburyo amazi abikwa muri mortiwo. Mortiwo ifite uburyo bwiza bwo kubika amazi ishobora gukomeza gukoreshwa igihe kirekire, ibyo bikaba ari ingenzi mu koroshya imirimo yo kubaka mu gihe cyo kubaka. Amazi menshi ashobora kubuza mortiwo kuma imburagihe no kunoza igihe cyo kubaka n'imikorere myiza ya mortiwo.
Gutatana: HPMC ishobora gukora umuti wa colloidal mu mazi, ushobora kunoza uburyo ibice bya mortiweri bitatana. Uburemere bw'uruvange rw'uruvange rw'uruvange ntibwita gusa ku rugero rwa sima, umucanga n'ibivanze, ahubwo bunafitanye isano ya hafi n'uburyo ibi bice bitatana. Mu guhindura ingano ya HPMC, ibice biri muri mortiweri bishobora gutatana neza, bityo bikarushaho kunoza uburyo uruvange rw'uru ...
Ingaruka zo gusya: HPMC ishobora gutuma ibice by'ibimera bikwirakwira neza mu gikoresho cyo mu bwoko bwa mortigo no kunoza imiterere yacyo. Mu kunoza ingaruka zo gusya, HPMC ishobora kugumana uburyo buhamye bwo gusya mu gikoresho cyo mu bwoko bwa mortigo mu gihe kirekire kandi ikarinda kugabanuka k'uburyo busanzwe bwo gusya bitewe n'igihe gito.
Ingaruka zo kongera ubuziranenge bw'ibice: Kongeramo HPMC bishobora no kongera ubuziranenge bw'ibice, bigatuma byoroha kubikoresha no kugira ubuziranenge bwiza mu gihe cyo kubaka. Urugero, iyo ushyira igikuta ku rukuta, ubuziranenge n'ubuziranenge bw'ibice bishobora kugabanya icyuho cy'ibice no kunoza ubwiza bw'ibice.
Uburyo bwiza bwo gukoresha HPMC mu gutunganya fluidity ya mortical:
Kugenzura igipimo: Igipimo cya HPMC bigira ingaruka zitaziguye ku kunyura kwa mortilage. Muri rusange, iyo ingano y’inyongera ya HPMC iri ku rugero ruciriritse, kunyura no kugumana amazi kwa mortilage bishobora kongerwa cyane. Ariko, HPMC irenze urugero ishobora gutuma ubushyuhe bwa mortilage buba bwinshi cyane, ibyo bigatuma kunyura kwayo kugabanuka. Kubwibyo, ingano ya HPMC yongewemo igomba kugenzurwa neza hakurikijwe ibikenewe byihariye mu ikoreshwa.
Guhuza n'izindi mvange: Uretse HPMC, izindi mvange zikunze kongerwa muri mortier, nka superplasticizers, retarders, nibindi. Guhuza hagati y'izi mvange na HPMC bishobora kugenzura neza urujya n'uruza rw'uruvange. Urugero, superplasticizers zishobora kugabanya ingano y'amazi muri mortier no kunoza uburyo mortier itemba, mu gihe HPMC ishobora kunoza uburyo amazi abikwamo n'imikorere yayo mu gihe ikomeza kuba nziza.
Guhindura ubwoko butandukanye bwa morti: Ubwoko butandukanye bwa morti bugira ibisabwa bitandukanye byo gutemba. Urugero, morti yo gusigwa ifite ibisabwa byinshi byo gutemba, mu gihe morti yo gusigwa yibanda cyane ku gufatanya kwayo n'ubugari bwayo. Muri iki gikorwa, ingano n'ubwoko bwa HPMC byongewemo bigomba kunozwa no guhindurwa hakurikijwe ibisabwa na morti zitandukanye kugira ngo habeho gutemba neza no kuringaniza.
Nk'inyongeramusaruro ikoreshwa cyane mu gusya,HPMCishobora guhindura neza uburyo ibintu bigenda bihinduka binyuze mu gukurura, kubika amazi, gukwirakwiza, gukoresha icyuma gishyushya, nibindi. Imiterere yayo yihariye ituma icyuma gishyushya kandi gihoraho mu gihe cyo kubaka. Ariko, ingano ya HPMC igomba guhindurwa neza hakurikijwe imiterere yihariye yo kuyikoresha kugira ngo hirindwe ko ikoreshwa cyane rigabanya amazi. Hamwe no kunoza imikorere y’ibikoresho bya icyuma gishyushya mu nganda z’ubwubatsi, ingaruka za HPMC zigenga imikorere yazo mu gihe kizaza zifite amahirwe menshi yo kuyikoresha.
