Gutezimbere ingaruka za hydroxypropyl methyl selulose kubikoresho bishingiye kuri sima

Hydroxypropyl methyl selulose

Gushiraho igihe

Igihe cyo gushiraho beto gifitanye isano cyane cyane nigihe cyo gushyiraho sima, ingaruka zose ntabwo ari nini, bityo rero igihe cyo gushiraho minisiteri gishobora gukoreshwa mu mwanya w’inyigo ya HPMC mu gihe cyo kugena beto yo munsi y’amazi, ingaruka z’uruvange bitewe n’igihe cyagenwe n’ikigereranyo cy’amazi ya sima ya minisiteri, ingaruka z’umusenyi wa sima hamwe n’igipimo cyagenwe na cima ya minisiteri.

HPMC ni imiterere ya macromolecule umurongo, hamwe nitsinda rya hydroxyl kumurwi ukora, rishobora gukora hydrogène ihuza hydrogène ivanze kandi ikongerera ubwiza bwamazi avanze. Iminyururu miremire ya HPMC izakurura, kugirango molekile ya HPMC ifatanye hamwe kugirango ibe imiterere y'urusobe, sima, ivanga amazi apfunyitse. Kuberako HPMC ikora imiterere y'urusobekerane rusa na firime yoroheje n'ingaruka zo gupfunyika sima, bizarinda neza guhumeka kw'amazi muri minisiteri, kubangamira cyangwa kugabanya umuvuduko w'amazi wa sima.

Ikizamini cyo kumena amazi

Ikintu cyo kuva amaraso mumazi ya minisiteri isa nicy'icyuma, kizatera gutuza gukomeye, biganisha ku kwiyongera kw'ikigereranyo cy'amazi-sima y'urwego rwo hejuru rwa slurry, kandi bigatuma urwego rwo hejuru rwa slurry rufite igabanuka rikomeye rya plastike cyangwa se rikavunika hakiri kare, kandi imbaraga z'ubuso bw'ubuso ni nkeya. Duhereye ku bushakashatsi, dushobora kubona ko iyo kuvanga biri hejuru ya 0.5%, nta kintu cyo kumena amazi. Ni ukubera igiheHPMCivangwa na minisiteri, HPMC ifite imiterere ya firime nuburyo bwurusobe, kimwe na adsorption ya hydroxyl kumurongo muremure wa macromolecules, kugirango sima muri minisiteri no kuvanga amazi bigizwe na flocculation, kugirango habeho imiterere ihamye yumubiri wa minisiteri. Nyuma yo kongera HPMC muri minisiteri, byinshi byigenga bito byigenga bizashirwaho. Ibibyimba bizagabanywa neza muri minisiteri kandi bibangamire gushira hamwe. HPMC imikorere ya tekiniki yibikoresho bishingiye kuri sima igira ingaruka zikomeye, akenshi ikoreshwa mugutegura nka minisiteri yumye, polymer mortar nibindi bikoresho bishya bya sima bishingiye ku bikoresho, kuburyo bifite amazi meza, plastike.
