Hydroxypropyl methylcellulose imwe yeakakosha cellulose ether additives mudhaka rakaoma uye ine mabasa akawanda mudhaka. Basa guru rehydroxypropyl methylcellulose mudhaka resimende kuchengetedza mvura uye kukora. Pamusoro pezvo, nekuda kwekudyidzana kwayo nesimende sisitimu, inogona zvakare kuita basa mukupinza mhepo, kudzoreredza kuseta, nekuvandudza tensile bond simba. Kufurira.
Kunyanya kukosha kwekuita kwehydroxypropyl methylcellulose mudhaka kuchengetedza mvura. Semusanganiswa we cellulose ether mudhaka, hydroxypropyl methylcellulose inogona kushandiswa mune zvingangoita zvese zvigadzirwa zvedhaka, kunyanya nekuda kwekuchengeta 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 kutaura, kukwirisa dhigirii rekutsiva uye viscosity ye cellulose ether, iyo idiki saizi yechikamu uye zvakanyanya kuoneka kukora kwemhedzisiro.
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 huwandu hwakakodzera hwemafuru mudhaka. Nekuda kwe "bhora mhedzisiro" yemabhuru,
Kuitwa kwekuvaka kwedhaka kunovandudzwa, nepo kuiswa kwemhepo inoputika kunowedzera goho revhu. Zvechokwadi, huwandu hwemhepo yakadzivirirwa inoda kudzorwa. Kana mhepo yakawandisa ichiiswa, inogona kukanganisa kusimba kwedhaka.
Hydroxypropyl methylcellulose inononoka kuseta simende, inonoke kumisa uye kuomesa simende, uye kuwedzera nguva yekuvhura yedhaka zvinoenderana. Nekudaro, mhedzisiro iyi haina kunaka kune dhaka munzvimbo dzinotonhora.
Sechinhu chakareba-cheni yepolymer chinhu, hydroxypropyl methylcellulose inogona kuvandudza kushanda kwechisungo nehwaro zvinhu uku ichinyatso chengetedza hunyoro hwehunyoro kana hwawedzerwa kune simende system.
Iwo makuru zvimiro zveHPMC mudhaka zvinosanganisira: kuchengetedza mvura, kukora, kuwedzera nguva yekuisa, kupinza mhepo, kuvandudza tensile bond simba, nezvimwe.
