Basa rakakosha rekunyungudika kwemvurahydroxypropyl methyl cellulose HPMCmudhaka yakakosha muzvikamu zvitatu, imwe inyanzvi yekuchengetedza mvura kugona, mbiri kukuvadzwa kweviscosity uye compressibility yedhaka, zvitatu ndiko kusangana nesamende. Kuchengetedzwa kwemvura kwakashata kwedhaka munzira yese yekufambisa kuri nyore kuparadzanisa kubuda kwemvura, kupararira pamusoro pezvinhu zvine porous, yakawanda yemvura iri nyore kunyudzwa kugaya, inoburitsa shanduko yedhaka, dhaka pasi kukuvara kwe zvese zvakajairika coagulation uye zvidimbu zvidiki zvezvimedu zviri pakati pekubatana uye saka kuderedza kusimba kwesimba remasonry madziro. Kuchengetwa kwemvura kwedhaka kunotsanangurwa ne stratification.
Iyo yakakura viscosity yehydroxypropyl methyl celluloseHPMC, iyo iri nani kuchengetedza kwemvura kuita, zviri nani iyo viscosity yepolymer aqueous mhinduro. Kureba uye chimiro checheni ye molecular zvakare zvinoenderana nehukama hwema molecular mass yepolymer (girazi rekuchinja tembiricha). Nhamba yemapoka anoshanda anokanganisawo viscosity range.
Hydroxypropyl methyl cellulose HPMC yega yekuchengeta mvura kuita kubva kuhydroxypropyl methyl cellulose pachayo solubility uye kumvura yekushandisa. Zvinonyatsozivikanwa kuti cellulose haina kunyungudika mumvura nekuda kwechimiro chayo chekristalline chakakwira, kunyangwe mamolecular cheni yefiber ine akawanda ane hydrated OH mapoka.
Iwo superstrong covalent bonds uye van der Waals masimba pakati pemamorekuru zvimiro haagone kubhadharwa nekugona hydration kwemapoka emethyl chete. Nokudaro, inogona kunyungudutswa chete mumvura. Kana mamorekuru anotsiviwa akaunzwa, kwete chete mamorekuru anotsiva anoparadza cheni yehydrogen, asiwo zvisungo zvakabatanidzwa muketani yehydrogen zvinoparadzwa neanotsiva mamorekuru wedges mumaketani akavakidzana. Kunyanya kutsiva, ndiko kukura kwakaita ma molecular spacing. Kunyanya kushandiswa kwekutyora covalent bonds. Kana iyo fiber lattice inogara ichiwedzera, mhinduro ine mvura inopinda uye hydroxypropyl methyl cellulose inonyungudika nemvura, zvichikonzera mhinduro ine viscous yakanyanya.
Sezvo tembiricha yakadzikama ichikwira, iyo polymer's hydration inoita shoma uye mvura inodzingwa pakati pecheni. Kana mvura yakakwana ikabviswa, chimiro chemolecular chinoungana zvishoma nezvishoma, chichigadzira network ine mativi matatu ematishu anogona kutambanudzwa. Iyo viscosity, dosage, particle size uye tembiricha yekushandisa yehydroxypropyl methyl cellulose ndizvo zvinhu zvinokuvadza kuchengetwa kwemvura kuita kwedhaka.
Hydroxypropyl methyl cellulose viscosity yakakamurwa kuva: viscosity 100,000, viscosity 150,000, viscosity 200,000.
Nzira yekusarudza hydroxypropyl methyl cellulose?
100,000 viscosity hydroxypropyl methyl cellulose inogona kushandiswa semukati wemadziro putty poda. Tile binder. Caulking agent. Bonded kongiri dhaka. High toughness isiri shrinkage grouting zvinhu.
Inorganic insulation insulation mortar yakatarwa yakakwira, viscosity ye150 zviuru hydroxypropyl methyl cellulose kana zviuru mazana maviri ehydroxypropyl methyl cellulose. Kana sarudza muchero mutsva kuti viscosity iri 100 zviuru, gadzira kuyerera kusungirira chiitiko nyore nyore.
Basa guru remethyl cellulose kuchengetedza mvura, inoteverwa nekukora. Kufinhwa nehupfu hwemwana mumadziro emukati, kana iine zvirinani kunyungudika kwemvura uye yakaderera viscosity (70000-80000), ichiri kushanda. Kana iyo viscosity inopfuura 100,000, iyo viscosity haina kukuvadza pakuchengetedza mvura. Mukugadzira uye kugadzirwa kwemukati madziro putty poda, hapana chikonzero chekusarudza 200,000 viscosity. Nekuti viscosity yakakura kwazvo, zvinonetsa kukwenya nekukwenya muhuwandu hukuru.
Hydroxypropyl methyl cellulose inoshandisa viscosity ye100,000.

Muzvivakwa zvekuvaka, kunyanya kushandiswa kwe inorganic insulating layer mortar, chinonyanya kukosha ndechekuvandudza kubatana, kuwedzera mhedzisiro yekusimba kwesimba, kuita kuti kongiri dhaka rive nyore kunama, kunatsiridza kugona. Mukuwedzera, ine anti-vertical liquidity effect. Kukwirisa kunyorova kuita kunogona kurebesa nguva yekumhanya yekongiri dhaka, kunatsiridza kutyoka kuramba uye anchoring, kunatsiridza mhando yepamusoro, kunatsiridza kunamatira.
(1) Kuchengetwa kwemvura kwemethyl cellulose kunoenderana nehuwandu hwayo hwekuwedzera, viscosity, particle fineness uye dissolution rate. Kazhinji, huwandu hwekuwedzera hwakakura, hunyoro hudiki, viscosity yakakura, mwero wekuchengetedza mvura wakakwira, pakati peiyo huwandu hwekuwedzera hune pesvedzero huru pachiyero chekuchengetedza mvura, viscosity uye mwero wekuchengetedza mvura hauna kuderera. kupfuura hukama, mwero wekunyungudika unonyanya kuenderana nedhigirii rekugadzirisa uye chidimbu chidiki che cellulose particles. Methyl cellulose uye hydroxypropyl methyl cellulose mune iri pamusoro akati wandei cellulose ethers ane yakakwirira yekuchengeta mvura mwero.
