Zvivakwa uye zviratidzo zviri nyore zvehydroxyprupyl methylcellose

HydroxyprEpyl methylcellose hpmc inowanzo shandiswa mukugadzirwa kwemukati uye yekudzvanya mari yekugadzira, celly zvinowanzoshandiswa. Viscosity Cellulose, ichi chigadzirwa chine yakanaka mvura yekuchengetwa, yakanaka inokonzeresa maitiro uye hunhu hwakagadzikana. HPMC inozoshandiswa zvakanyanya muindasitiri yekuvaka uye inoshandiswa mune yakakura mari. Cellulose inogona kushandiswa seyedzorwe, mvura yekuchengetwa kwemvura, thickener uye binder. Cellulose ether inobata basa rakakosha mune yakajairika yakaoma-yakasanganiswa madziro, yekuzvimiririra mhou, etcer stucco system.

Inowanzoshandiswa cellulose ether inosanganisira hec, hpmc, cmc, pac, mhec, etc. HPMC, MC Kana EHEC inoshandiswa mune yakawanda yeComment-yakavakirwa mauto, yakadai simende, inosimbisa iyo kufambisa, iyo inokoshesa zvakanyanya kudiwa, iyo yakakosha kwazvo kune plaster, tily siment uye putty. HEC inoshandiswa musike, kwete seyenga chete, asiwo semumiriri wekuchengetedza mvura, uye Hehpc inoshandiswawo mune izvi. MC kana Hec anowanzo shandiswa pamwe chete neCMC sechikamu chakasimba cheWallpaper. Pakati-viscosity kana yakakwirira-viscosity cellulose mherender inoshandiswa muWallpaper Glued Zvivakwa Zvivakwa zvekuvaka.

Zvivakwa zveHydroxyPropyl methylcellose

HydroxyPropyl methylcellose HPMC zvigadzirwa zvinosanganisa akawanda akawanda emuviri uye makemikari zvivakwa kuti uve chigadzirwa chakasarudzika chine akawanda mashandisiro ekushandisa. Zvivakwa zvakasiyana-siyana zviri seanotevera:

Zvakajairika uye nyore nzira dzekuziva kunaka

1. Yakachena HPMC ndeyekuona fluffy uye ine yakaderera bulk density, inotanga kubva 0.3-0G / ml; Hpmc HPMC ine zvishoma zvishoma uye inonzwa inorema, iyo iri pachena yakasiyana neyakagadzirwa neyakagadzirwa nechitarisiko.

2.. Kuenzaniswa neakarondedzerwa mherether cellow zvigadzirwa, zvinogona kuoneka kuti kuchena kweiyo yakanaka cellulose etera chigadzirwa chinogara chiri nani pane izvo zvezvikamu zvechipiri zvezvikamu zvechipiri.

3. Yakachena HPMC yemvura mhinduro yakajeka, yakakwirira yechiedza chinoputika, kudzokorora kwemvura ≥ 97%; Hpm Commc Mvura mhinduro ndeye turbid, uye iyo mvura yekuchengetedza mvura yakaoma kuita zvinodiwa. Iko kujekesa kwechiedza kwemhinduro yakanaka yakanaka, iyo inoratidza kuti chigadzirwa chine zvinhu zvisina kujairika uye zvine zvirimo zvakakwirira zvezvinhu zvinoshanda.

4 HpMC HPMC inowanzo kunhuhwirira marudzi ese ekunhuhwirira, kunyangwe isina kusimba, ichanzwa kurema.

5. Yakachena HPMC poda iri fibrous pasi peiyo microscope kana girazi rekukudza; HpMC HPMC inogona kucherechedzwa sedono solids kana makristasi pasi pe microscope kana girazi rekukudza.

6 Kana iyo ash yakasara / cellulose ether ± 5%, iyo fiber iyo mhando yejeko ether isingabvumirwe. (Dzimwe nguva pane zvikanganiso mune iyi nzira

7. Vamwe vagadziri vakaneta mari diki yeCMC muHydroxyprupyl methyl cell Iyo CMC Makwikwi mhinduro uye Calcium apo, Magnesium, uye munyu wemunyu, hapana kufungidzira kuchaitika, asi visikopa yeCMC yemakwikwi mhinduro ichaderedzwa.

8. Kana mamiriro ezvinhu akabvumira, zvakananga viscosity yemamiriro ekunze emasero e cellaulose ether uye enzanisa mwero wekuchengetwa kwemvura-vhoriyamu cellulose etther.
