Hydroxymethylcellulose irasa na hydroxypropyl methylcellulose?

Carboxymethyl selulose (Carboxymethyl selulose) ikorwa nigisubizo cyitsinda rya hydroxyl ryurwego rwa anhydroglucose kumurongo wa selile hamwe nitsinda rya etherification (aside chloro Z cyangwa okiside ya Ethylene);

Nibintu bitagira ibara bya amorphous bishonga mumazi, umuti wa alkali wamazi, ammonia numuti wa selile, udashonga mumuti kama namavuta yubutare; irashobora gukoreshwa nkubunini, kalendari hamwe nububyibushye mubikorwa byimyenda;

Kubaka abakozi mu mpapuro no kubyaza umusaruro;

Gusubiramo umwanda mubikoresho byogukora isuku;

Umukozi wa Flotation muguhitamo umuringa-nikel na potasiyumu;

Viscous guhagarika umubyimba hamwe na stabilisateur mugihe ucukura amariba ya peteroli na gaze;

ibihimbano bya kole ya wallpaper;

ibyuma byubaka byumye bivanze;

Amazi ya latx yamabara, nibindi.

Hydroxypropyl methylcellulose (Hypromellose, Cellulose) ikozwe muri selile nziza cyane ya selile nk'ibikoresho fatizo, byera cyane cyane mu bihe bya alkaline, kandi ntibirimo ibintu bifatika nk'ingingo z'inyamaswa n'amavuta. Gushonga mumazi hamwe na polar nyinshi hamwe nuburinganire bukwiye bwa Ethanol / amazi, propanol / amazi, dichloroethane, nibindi, bitangirika muri ether, acetone, na Ethanol yuzuye, hanyuma bikabyimba mubisubizo bisobanutse cyangwa bitobito byoroheje mumazi akonje. Igisubizo cyamazi gifite ibikorwa byubuso, gukorera mu mucyo no gukora neza.

HPMC ifite umutungo wa gelasique. Igicuruzwa cyamazi yo mumazi arashyuha kugirango akore gel hanyuma agwe, hanyuma ashonga nyuma yo gukonja. Ubushyuhe bwa gelation bwibintu bitandukanye buratandukanye. Gukemura biratandukanye nubwiza. Hasi ya viscosity, niko gukomera. Ibisobanuro bitandukanye bya HPMC bifite itandukaniro mubintu byabo. Iseswa rya HPMC mumazi ntabwo rihindurwa nagaciro ka pH.
