Seimwe yeanokosha cellulose ether admixtures muvhu rakaoma dhaka, hydroxypropyl methylcellulose ine mabasa akawanda mudhaka. Basa rakakosha rehydroxypropyl methylcellulose mudhaka resimende kuchengetedza mvura uye kukora. Pamusoro pezvo, nekuda kwekudyidzana kwayo nesimende sisitimu, inogona zvakare kuita basa rekubatsira mukupinza mweya, kudzoreredza kuseta, nekuvandudza tensile bond simba. effect.
Kunyanya kukosha kwekuita kwehydroxypropyl methylcellulose mudhaka kuchengetedza mvura. Semusanganiswa we cellulose ether mudhaka, hydroxypropyl methylcellulose inogona kushandiswa mune zvinenge zvese zvigadzirwa zvedhaka, kunyanya nekuda kwekuchengetedza kwayo mvura. Kazhinji kutaura, kuchengetwa kwemvura kwehydroxypropyl methylcellulose kune hukama neiyo viscosity, dhigirii rekutsiva uye saizi yechikamu.
Hydroxypropyl methylcellulose inoshandiswa seyakakora, uye kukora kwayo kunoenderana nedhigirii rekutsinhanisa, particle size, viscosity uye dhigirii rekushandurwa kwehydroxypropyl methylcellulose. Kazhinji, kukwirisa dhigirii rekutsiva uye viscosity ye cellulose ether, uye diki zvidimbu, zvinova pachena zvakanyanya kukora mhedzisiro.
Mu hydroxypropyl methylcellulose, kuiswa kwemethoxy mapoka kunoderedza simba repamusoro remushonga wemvura une hydroxypropyl methylcellulose, kuitira kuti hydroxypropyl methylcellulose ive nemhepo-inopinza mhepo pamatope esimende. Isai mabhuru emhepo akakodzera mudhaka, nekuda kwe "bhora mhedzisiro" yemabhuru emhepo,
Kuitwa kwekuvaka kwedhaka kunovandudzwa, uye panguva imwe chete, kuiswa kwemhepo inoputika kunowedzera chiyero chekubuda kwedhaka. Zvechokwadi, kuwanda kwemhepo-kupinza kunoda kudzorwa. Kuwanda kwemhepo-kupinza kuchava nemigumisiro yakaipa pakusimba kwedhaka.
Hydroxypropyl methylcellulose inononotsa kuseta simende, nokudaro ichideredza kugadzika uye kuomesa simende, uye kuwedzera nguva yekuvhurwa kwedhaka zvinoenderana, asi izvi hazvina kunaka kune dhaka munzvimbo dzinotonhora.
Sechinhu chakareba-cheni yepolymer chinhu, hydroxypropyl methylcellulose inogona kuvandudza mashandiro ekubatanidza neiyo substrate mushure mekuwedzera kune simende system pasi pemamiriro ekuchengetedza zvizere hunyoro mune slurry.
Kupfupisa, kuita kweHPMCmudhaka rinonyanya kusanganisira: kuchengetedza mvura, kukora, kurebesa nguva yekumisikidza, kupinza mweya uye kuvandudza tensile bond simba, nezvimwe.
