Mu gishishwa cya sima n'igishishwa gishingiye kuri gypsum, hydroxypropyl methylcellulose igira uruhare mu kubika amazi no kuyagwingira, kandi ishobora kunoza neza uburyo igishishwa gifatana n'ubudahangarwa bwacyo.
Ibintu nk'ubushyuhe bw'umwuka, ubushyuhe n'umuvuduko w'umuyaga bigira ingaruka ku gipimo cyo guhindagurika kw'amazi mu gikoresho cya sima n'ibikomoka kuri gypsum. Kubwibyo, mu bihe bitandukanye, hari itandukaniro mu ngaruka zo kubika amazi ku bicuruzwa bifite ingano imwe ya hydroxypropyl methylcellulose yongewemo. Mu buryo bwihariye, ingaruka zo kubika amazi ku gikoresho cyo gusya zishobora guhindurwa no kongera cyangwa kugabanya ingano ya HPMC yongewemo. Kubika amazi mu gihe cy'ubushyuhe bwinshi ni ikimenyetso cy'ingenzi cyo gutandukanya ubwiza bwa hydroxypropyl methylcellulose ether.
Ibicuruzwa byiza cyane bya hydroxypropyl methylcellulose bishobora gukemura neza ikibazo cyo kubika amazi mu gihe cy'ubushyuhe bwinshi. Mu bihe by'ubushyuhe bwinshi, cyane cyane mu bice bishyushye kandi byumye hamwe n'imiterere y'urwego ruciriritse ku ruhande rw'izuba, HPMC nziza irakenewe kugira ngo yongere uburyo amazi abikwamo. HPMC nziza ifite ubushobozi bwo guhuza neza. Amatsinda yayo ya methoxy na hydroxypropoxy akwirakwira ku buryo bungana ku ruhererekane rwa molekile ya cellulose, ibi bikaba bishobora kunoza ubushobozi bwa atome za ogisijeni ku migozi ya hydroxyl na ether bwo kwihuza n'amazi kugira ngo bikore imigozi ya hydrogen. , bityo amazi yigenga aba amazi afatanye, kugira ngo agenzure neza uburyo amazi ahinduka mu kirere bitewe n'ubushyuhe bwinshi, kandi agere ku migozi myinshi y'amazi.
Hydroxypropyl methylcellulose nziza cyane ishobora gukwirakwizwa mu buryo bumwe kandi neza mu bintu bikozwe muri sima no muri gypsum, igapfunyika uduce twose tw’ingenzi, igakora agahu ko kunywesha, kandi ubushuhe mu gice cyo hasi bugasohoka buhoro buhoro mu gihe kirekire, hamwe n’uburyo bwo guhumeka hamwe n’ibikoresho bitagira umwimerere bya gelling kugira ngo bikomeze gufatana no gukomera kw’ibikoresho.
Kubwibyo, mu bwubatsi bushyuha cyane mu mpeshyi, kugira ngo amazi agerweho, ni ngombwa kongeramo ibikoresho bya HPMC byiza bihagije hakurikijwe formula, bitabaye ibyo, amazi ntahagije azaba ahari, imbaraga nke, gucikamo ibice, gupfuka no gushonga bitewe n'ibibazo byumye cyane, ariko nanone byongera ingorane z'abakozi mu bwubatsi. Uko ubushyuhe bugenda bugabanuka, ingano ya HPMC yongewemo ishobora kugabanuka buhoro buhoro, kandi ingaruka imwe yo kubika amazi ishobora kugerwaho.
