Hydroxypropyl methyl selulose HPMC ifite ahanini ibishishwa bitatu, HPMC-100000, HPMC-150000, na HPMC-200000. Muri rusange, hydroxypropyl methyl selulose ifite ubwiza bwa 100.000 ikoreshwa muburyo bwo gukora ifu yimbere yimbere ninyuma. Cellulose ifite ubwiza bwa 200.000 kandi ikoreshwa mubikoresho byubaka nka minisiteri yumye, ibyondo byoroshye byamabuye, icyondo cya diatom, no gutwikira urukuta. Igicuruzwa gifite ingaruka nziza zo gufata amazi, ingaruka nziza yo kubyimba, ubwiza buhamye nigiciro cyiza.
Hydroxypropyl methylcellulose HPMC ikoreshwa cyane mubikorwa byubwubatsi. Umubare munini wa selile urashobora gukoreshwa nka retarder, agent igumana amazi, kubyimbye no guhuza. Cellulose ether igira uruhare runini mumyanda isanzwe yumye-ivanze, minisiteri yimbere yo hejuru yinkuta zo hejuru, minisiteri yo kwisiga, ifu yumye yometseho ifu, ceramic tile ihuza ifu yumye yumye, inyubako ikora neza cyane, imbere-imbere. urukuta rushyizwemo, nibindi, bitarimo amazi yumye-kuvanga minisiteri, plaque gypsumu, gusiba ibikoresho byera, guhuza ibice bito nibindi bikoresho. Zifite uruhare runini mu gufata amazi, ibisabwa n’amazi, kumererwa neza, kudindiza no gukora bya sisitemu ya stucco. Ubusanzwe ether ya selile ikoreshwa mubikorwa byubwubatsi harimo HEC, HPMC, CMC, PAC, MHEC, nibindi.
Nonionic water-soluble selulose ethers ni ingirakamaro zubaka ibikoresho kubera imiterere yabyo, guhuza ibidukikije, hamwe nubushobozi bwo gufata amazi. HPMC, MC cyangwa EHEC bikoreshwa mubwubatsi bushingiye kuri sima cyangwa gypsumu, nka minisiteri ya masonry, minima ya sima, cima ciment, gypsum, ivangwa rya sima hamwe na emulsiyo, nibindi, bishobora kuzamura ikwirakwizwa rya sima cyangwa umucanga kandi bigatera imbere cyane gufatira hamwe, bifite akamaro kanini kuri plaster, sima ya tile na putty. Kuri sima, HEC ntabwo isubiza inyuma gusa, ahubwo ni n'umukozi ubika amazi. HEHPC nayo ifite iyi ntego. Ether ya selile ikoreshwa kenshi hamwe na gluconate muri minisiteri nkinyongera zingirakamaro. MC cyangwa HEC na CMC bikunze gukoreshwa nkigice gikomeye cya wallpaper. Ethers yo hagati cyangwa hejuru ya viscosity selulose ethers ikoreshwa mubisanzwe bifata amashusho hamwe nibikoresho byubaka.
Hydroxypropyl methylcellulose Igicuruzwa cya HPMC gihuza ibintu byinshi byumubiri nubumashini kugirango bibe ibicuruzwa bidasanzwe hamwe nibikoreshwa byinshi. Imitungo itandukanye niyi ikurikira:
.
.
.

(7) Kurinda colloid: Irashobora gukumira ibitonyanga nuduce duhurira hamwe.
.
.
.
(11) Acide-ishingiro ihamye: ibereye gukoreshwa murwego rwa pH ya 3.0-11.0.
(12) Uburyohe kandi butagira impumuro nziza, ntibiterwa na metabolism; ikoreshwa nk'inyongera mu biribwa no mu buvuzi, ntabwo ihinduranya mu biryo kandi ntabwo itanga karori.
Kubwibyo, hydroxypropyl methylcellulose HPMC ifite umwanya wingenzi mubikorwa byubwubatsi, kandi selile selile izakoreshwa cyane mubikorwa byubwubatsi. Ubwiza buhanitse, ibiciro byingirakamaro hamwe na serivise nziza nibyo uruganda rwacu rwa selile na latex rwamavuta rwakurikiranye. Umunsi w'ejo hazaza hubahirizwa na filozofiya y'ubucuruzi yo “kubaho ku bwiza, iterambere rya siyansi n'ikoranabuhanga, isoko ku izina, no gukora neza n'ubuyobozi”. Hydroxypropyl methylcellulose, ifu ya redxersible latex, na hydroxyethyl selulose itanga ibicuruzwa byiza cyane kubakiriya benshi.
