Hydroxypropylmethylcellulose HPMC ikwirakwiza, ikabyimbye kandi ihuza mugutunganya inyubako

Hydroxypropyl methylcellulose HPMC ikoreshwa cyane cyane mugushushanya sima ya sima na gypsumu nkibisaranganya, kubyimbye no guhuza mugutunganya inyubako. Ikoreshwa muri sima ya sima kugirango yongere ubufatanye, igabanye flokculasiyo, itezimbere ubwiza no kugabanuka, kandi ifite amazi. Kugabanya igihombo cyamazi nimbaraga zubutaka bwa beto, wirinde gucikamo nikirere cyumunyu ushonga amazi; Hydroxypropyl methylcellulose HPMC ifite thixotropy, ishobora gukoreshwa mugutegura irangi rya minisiteri ntoya ishobora gukoreshwa kurukuta ruhagaze mwikoti rimwe; HPMC itezimbere hamwe no gukora, birakwiriye rero ko hategurwa uburyo bworoshye bwo gutera imiti yo gusiga irangi.
Ingano ya HPMC ikoreshwa mubikoresho byo kubaka ni nto cyane, 0.1% ~ 1% gusa, ariko ifite ingaruka zikomeye. Irashobora gukoreshwa nka plasitike, tackifier, ibikoresho bigumana amazi, ibikoresho byinjira mu kirere hamwe na retarder yo gusiga amarangi, pompa, minisiteri na sima, kugirango byongere imikorere yayo, kubika amazi cyangwa guhuza inzira yibanze. Byongeye kandi, ukurikije ibisabwa mu kurengera ibidukikije, iyo ivanze ryumye, imikorere idahwitse iterwa no kuvanga aho hantu, umwanda ku bidukikije, ibidukikije byubaka ndetse n’imikorere idahwitse biririndwa. Ibifata kumatafari yubutaka hamwe nimbere ninyuma yurukuta rwashyizwemo 107. Urebye kurengera ibidukikije, selile ether nibyiza, nka HEC na HPMC.
Isima ifite imikorere myiza yo guhuza, ariko imikorere yo guhuza sima ya sima na minisiteri ya sima biragaragara ko itandukanye bitewe nuburyo butandukanye mumikorere n'imiterere hagati yuburinganire nubuso bwubatswe mugihe cyo kubaka. Iyo imikorere yo kwinjiza amazi yubuso bunini ari nini, bizatera umwuma wubuso buhuza, bigabanye cyane plastike hamwe no gufatira kumasima ya sima, kandi bigabanya cyane imbaraga zo guhuza. Mu bihe byashize, gypsumu cyangwa kole 107 byongerwaga kuri sima ya sima, ariko haracyari inenge nko gupima nabi hamwe nubuhanga bwubaka bwubaka. Viscosity yongera ingaruka za selulose ether mumazi na base base.
Ingaruka za selile yongeyeho harimo:
1. Kunoza igihe cyambere nicyanyuma cyo gushiraho sima;
2. Kunoza imihangayiko ya sima;
3. Kunoza ubushobozi bwo gufata amazi ya sima na gypsumu;
4. Imbaraga zo guhonyora hamwe nimbaraga zo gukata za sima zigabanuka;
5. Kunoza imikorere yo guhuza minisiteri.
