Ethers ikoreshwa cyane muri selile harimo HEC, HPMC, CMC, PAC, MHEC, nibindi. HPMC, MC cyangwa EHEC bikoreshwa mu nyubako nyinshi zishingiye kuri sima cyangwa gypsumu, nka minisiteri ya masonry, minima ya sima, cima ciment, gypsum, imvange ya sima hamwe namata yamata, nibindi, bishobora kuzamura ikwirakwizwa rya sima cyangwa umucanga na kunoza cyane Adhesion, ifite akamaro kanini kuri plaster, tile sima na putty. HEC ikoreshwa muri sima, ntabwo ari retarder gusa, ahubwo ikoreshwa nkibikoresho byo gufata amazi, kandi HEHPC nayo ikoreshwa muriki kibazo. MC cyangwa HEC ikoreshwa kenshi hamwe na CMC nkigice gikomeye cyurukuta. Hagati ya viscosity cyangwa selile-selile nyinshi ya selile ikoreshwa mububiko bwa kashe yometseho ibikoresho.
Hydroxypropyl methylcelluloseHPMCmuri rusange ikoreshwa mugukora ifu yimbere ninyuma yinyuma ya putty ifu ifite ubwiza bwa selile 100.000, mumashanyarazi yumye yumye, icyondo cya diatom nibindi bikoresho byubaka, selile hamwe nubwiza bwa 200.000 ikoreshwa cyane, no mukwishyira ukizana nibindi minisiteri idasanzwe, selile ifite viscosity ya 400 ikoreshwa cyane. Viscosity selulose, iki gicuruzwa gifite ingaruka nziza zo gufata amazi, ingaruka nziza yo kubyimba hamwe nubwiza buhamye. HPMC ikoreshwa cyane mubikorwa byubwubatsi kandi ikoreshwa mubwinshi. Cellulose irashobora gukoreshwa nka retarder, agent yo kubika amazi, kubyimba no guhuza. Ether ya selulose igira uruhare runini mubutaka busanzwe bwumye buvanze, minisiteri yo gukingira urukuta rwo hanze, minisiteri yipima, ifu yumye yometseho ifu, ifu ya tile ihuza ifu, ifu yimbuto, urukuta rwimbere ninyuma rushyizwemo, minisiteri idafite amazi, ingingo zoroshye, nibindi. ., zifite uruhare runini mu gufata amazi, gukenera amazi, gukomera, kudindira no gukora bya sisitemu ya stucco.
Hydroxypropyl methylcellulose Ibicuruzwa bya HPMC bihuza ibintu byinshi byumubiri nubumashini kugirango bibe ibicuruzwa bidasanzwe hamwe nibikoreshwa byinshi. Imitungo itandukanye niyi ikurikira:
Ret Kubungabunga amazi: Irashobora kugumana ubushuhe hejuru yubutaka nkibibaho bya sima n amatafari.
Forming Gukora firime: Irashobora gukora firime ibonerana, ikomeye kandi yoroshye hamwe na peteroli nziza cyane.
Sol Solubility Organic: Igicuruzwa gishobora gushonga mumashanyarazi amwe n'amwe, nka Ethanol / amazi, propanol / amazi, dichloroethane hamwe na sisitemu ikora igizwe na solge ebyiri.
Ge Ubushyuhe bwa Thermal: Igisubizo cyamazi yibicuruzwa bizakora gel iyo bishyushye, kandi gel yashizweho izongera kuba igisubizo nyuma yo gukonja.
Activity Igikorwa cyubuso: Tanga ibikorwa byubuso mubisubizo kugirango ugere kuri emulisation isabwa hamwe na colloid ikingira, hamwe no guhagarika icyiciro.
Guhagarikwa: Hydroxypropyl methylcellulose irashobora kubuza uduce duto duto gutuza, bityo bikabuza imvura.
◆ Kurinda colloid: Irashobora kubuza ibitonyanga nuduce guhuriza hamwe cyangwa guterana.
◆ Gufata neza: Byakoreshejwe nk'ibiti bifatika, ibikomoka ku itabi, n'ibicuruzwa by'impapuro, bifite imikorere myiza.
Sol Amazi meza: Igicuruzwa gishobora gushonga mumazi mubwinshi, kandi ubunini bwacyo bugarukira gusa kubwiza.
In Ubusembure butari ionic: Igicuruzwa ni ether ya selile ya ionic selile, idahuza numunyu wicyuma cyangwa izindi ion kugirango habeho imvura idashonga.
Acide Acide-ishingiro ihamye: ikwiriye gukoreshwa murwego rwa PH3.0-11.0.
◆ Uburyohe kandi butagira impumuro nziza, ntibiterwa na metabolism; ikoreshwa nkibiryo byongera ibiyobyabwenge, ntabwo bizahinduka mubiryo, kandi ntibizatanga ubushyuhe.
