Na hydroxymethylcellulose e tšoana le hydroxypropyl methylcellulose?

Carboxymethyl cellulose (Carboxymethyl cellulose) e thehoa ke karabelo ea sehlopha sa hydroxyl sa unit ea anhydroglucose ka ketane ea cellulose le sehlopha sa etherification (chloro Z acid kapa ethylene oxide);

Ke ntho e se nang 'mala ea amorphous e qhibilihang ka metsing, tharollo ea alkali e nang le metsi, ammonia le selulose tharollo, e ke keng ea qhibiliha ka tharollo ea manyolo le oli ea diminerale; e ka sebelisoa e le sesebelisoa sa boholo, calendering le thickening indastering ea masela;

Setsi sa tlhophiso tlhahisong ea pampiri le boto;

Ho kenngoa bocha ha litšila ka har'a li-agent tsa ho hloekisa tsa maiketsetso;

Moemeli oa Flotation bakeng sa ho khetha koporo-nickel le ore ea potasiamo;

Viscous suspension thickener le stabilizer ha ho cheka liliba tsa oli le khase;

sebopeho sa sekhomaretsi bakeng sa Wallpaper;

likarolo tse omileng tsa motsoako oa kaho;

Likarolo tsa pente ea latex ea metsi, joalo-joalo.

Hydroxypropyl methylcellulose (Hypromellose, Cellulose) e entsoe ka selulose ea k'hothone e hloekileng haholo e le thepa e tala, e hlahisoang ka ho khetheha tlas'a maemo a alkaline, 'me ha e na lisebelisoa leha e le life tse sebetsang tse kang litho tsa liphoofolo le oli. E qhibiliha ka metsing le boholo ba polar le likarolo tse loketseng tsa ethanol / metsi, propanol / metsi, dichloroethane, joalo-joalo, e sa qhibilihe ka har'a ether, acetone, le absolute ethanol, 'me e ruruha ho ba tharollo e hlakileng kapa e nyenyane ea colloidal metsing a batang. Tharollo ea metsi e na le mosebetsi oa holim'a metsi, pepeneneng e phahameng le ts'ebetso e tsitsitseng.

HPMC e na le thepa ea gelation ea mocheso. Sehlahisoa tharollo ea aqueous e futhumetse ho etsa gel le precipitates, ebe e qhibiliha ka mor'a ho pholile. Mocheso oa gelation oa litlhaloso tse fapaneng o fapane. Sollubility e fapana ho ea ka viscosity. The viscosity e ka tlaase, e kholoanyane ea ho qhibiliha. Litlhaloso tse fapaneng tsa HPMC li na le phapang e itseng ea thepa ea bona. Ho qhalana ha HPMC metsing ha ho amehe ke boleng ba pH.
