Hydroxypropyl Methyl Cellulose HPMC
1. Iine kugadzikana kweasidhi uye alkali, uye mhinduro yayo ine aqueous yakanyatsogadzikana mu pH = 2 ~ 12 range. Caustic pasoda nemvura yeraimu haina mhedzisiro yakawanda pakuita kwayo, asi alkali inogona kukurumidza kunyungudika kwayo uye inovandudza zvishoma viscosity.
2. HPMCchinhu chinoshanda chekuchengetedza mvuradhaka rakaomasisitimu, iyo inogona kuderedza chiyero chekuvharira kwedhaka uye stratification, kuvandudza kubatanidzwa kwedhaka, kuvharidzira zvinobudirira kuumbwa kwematope epurasitiki kuputika, uye kuderedza dhaka repurasitiki rinoputika index.
3, iyo isiri-ionic uye isiri-polymeric electrolyte, iyo yakanyatsogadzikana mune aqueous mhinduro yesimbi yemunyu uye organic electrolytes, uye inogona kuwedzerwa kune zvekuvaka kwenguva yakareba kuti ive nechokwadi chekuti kusimba kwayo kunovandudzwa.
4, kushanda kwekushanda kwedhaka kwakagadziridzwa zvakanyanya, dhaka rinoita seine "mafuta", rinogona kuita kuti rusvingo rwakabatana ruzere, rwakatsetseka pamusoro, kuitira kuti dhaka uye chisungo chigadzikane zvakasimba, uye chinogona kuwedzera nguva yekushanda.
Kuchengetedza mvura
Kuzadzikiswa kwekurapa kwemukati kunobatsira kuvandudzwa kwesimba renguva refu, kudziviswa kwekubuda ropa, kudzivirira kwekugara kwedhaka, shrinkage uye kuvandudzwa kwekupokana kwedhaka.
Kukora
Dzivirira kupatsanurwa, kunatsiridza kufanana kwedhaka, kunatsiridza iyo yakanyorova chisungo simba, uye kunatsiridza iyo anti-yakarembera kuita.
Kupinza mweya
Kuvandudza kuita kwedhaka. Nekukwirira kwe viscosity ye cellulose, kureba kwema molecular cheni, kunowedzera kuoneka kwemhepo inopinda mukati.
Kunonoka coagulation
Batira pamwe nekuchengetedza mvura kuwedzera nguva yekuvhura yedhaka
Hydroxypropyl Starch ether
1. Iyo yakakwira hydroxypropyl yemukati mu starch ether inopa sisitimu yakagadzikana hydrophilicity, ichishandura mvura yemahara mumvura yakasungwa, iyo inoita basa rakanaka rekuchengetedza mvura.
2. Starch ethers ine zvakasiyana hydroxypropyl zvirimo vane hunyanzvi hwakasiyana hwekubatsira cellulose mukuchengetedza mvura pachiyero chimwe chete.
3. Kutsiva kweboka rehydroxypropyl kunowedzera dhigirii rekuzvimba mumvura uye kunomanikidza nzvimbo yekuyerera kwechidimbu, nokudaro kuwana mhedzisiro yekukora uye viscosity ichiwedzera.
Thixotropic lubricity
Starch ether inokurumidza kuparadzirwa mumatope, ichishandura rheology yedhaka uye ichipa thixotropy. Kana simba rekunze rinoshandiswa, viscosity yedhaka ichaderedzwa, kuve nechokwadi chekuvaka kwakanaka uye kupomba, uye kuipa thixotropy. Iine kunzwa kwakatsetseka. Kana simba rekunze rabviswa, iyo viscosity inowedzera, ichipa iyo dhaka kuramba kwakanaka pakudonha. Pakati peputty powders, ine zvakanakira kuvandudza kupenya kweputty mafuta uye kupenya kupenya.
Yekubatsira kuchengetedza mvura
Starch ether pachayo ine hydrophilic properties nekuda kwebasa re hydroxypropyl mapoka muhurongwa. Kana yakasanganiswa ne cellulose kana kuwedzerwa mune imwe chiyero kune dhaka, inogona kuwedzera kuchengetwa kwemvura kune imwe nhanho uye kugadzirisa pamusoro pekuomesa nguva.
Anti-sag uye anti-slip
Yakanakisa anti-sag mhedzisiro uye kuumba maitiro.
Redispersible polymer hupfu
1. Kuvandudza kushanda kwedhaka.Redispersible powder or RDPzvidimbu zvakaparadzirwa muhurongwa, zvichipa iyo system mvura yakanaka uye inovandudza kushanda uye kushanda kwedhaka.
2. Kuvandudza kusimba kwekubatanidza kwedhaka. Mushure mehupfu yerabha yakaparadzirwa mufirimu, iyo inorganic uye organic zvinhu mumatope system inogona kusanganiswa pamwechete. Zvinogona kufungidzirwa kuti simenti nejecha mudhaka ndiyo mapfupa, uye latex powder inoumba masumbu. Kubatana kunowedzera, simba rinowedzera, uye chimiro chinoshanduka chinoumbwa zvishoma nezvishoma.
3. Kuvandudza kupikisa kwemamiriro ekunze kwedhaka. Freeze-thaw resistant latex powder is thermoplastic resin ine yakanaka flexible, iyo inogona kuita kuti dhaka ripindure kune kunze kwekuchinja kwekutonhora uye kupisa, zvinobudirira kudzivirira dhaka kubva pakutsemuka nekuda kwekushanduka kwekushisa.
4. Kuvandudza flexural simba redhaka. Iyo polymer uye simende slurry inoumba mabhenefiti ekuwedzera. Kana kutsemuka kuchikonzerwa nemasimba ekunze, iyo polima inogona kutenderedza kuputika uye kuvharidzira kuwedzera kwekutsemuka, nekudaro ichivandudza kusimba kwekutsemuka uye kuremara kwedhaka.
