suma:
Cellulose ethers inoshandiswa zvakanyanya muindasitiri yekuvaka nekuda kwekunaka kwekuchengetedza mvura, kukora uye kusungirira zvivakwa.Ivo vanovandudza kuyerera uye processability yesimende-yakavakirwa zvinhu uye vanovandudza ma mechanic zvimiro zvechigadzirwa chekupedzisira.Putties anowanzoshandiswa muindasitiri yekuvaka kuzadza makatsemuka, maburi uye kumwe kusakwana mumadziro uye sirin'i.Kushandiswa kwe cellulose ethers mu putty powders kunogona kuvandudza kushanda, kuisa nguva uye hutano hwese hwechigadzirwa.Ichi chinyorwa chichakurukura mhedzisiro yeviscosities yakasiyana ye cellulose ethers pane putty powder.
Mhando dze cellulose ethers:
Kune mhando dzakasiyana dze cellulose ethers dzinosanganisira methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) uye carboxymethylcellulose (CMC).HPMC yakakurumbira cellulose ether muindasitiri yekuvaka nekuda kwekuchengetedza kwayo mvura zvakanaka, kukora uye kunamatira zvivakwa.HPMC inouya mune zvakasiyana viscosities, kubva pasi kusvika kumusoro.
Mhedzisiro ye cellulose ether pane putty poda:
Putty poda inoshandiswa kuzadza kuputika, maburi uye kumwe kusakwana mumadziro uye matenga.Kushandiswa kwe cellulose ethers mu putty powders kunogona kuvandudza kushanda uye kuisa nguva yechigadzirwa.Cellulose ether inogonawo kuvandudza kushanda uye kunamatira kweputty powder.Izvi zvinotevera mhedzisiro yemaviscosities akasiyana e cellulose ethers pane putty poda:
1. Low viscosity HPMC:
Low viscosity HPMC inogona kuvandudza fluidity uye kushanda kweputty powder.Inovandudzawo nguva yekugadzika kwechigadzirwa.Low-viscosity HPMC ine yakadzika gelation tembiricha, izvo zvinogona kudzivirira putty poda kubva kuoma nokukurumidza.Inogonawo kuvandudza kusungirirwa uye kubatana kwechigadzirwa.Low viscosity HPMC inokodzera putty poda inoda kushanda zvakanaka uye kutsetseka.
2. Medium viscosity HPMC:
Medium viscosity HPMC inogona kuvandudza iyo thixotropic zvimiro zveputty poda.Inogonawo kuvandudza kuchengetwa kwemvura uye kusungirirwa kwekuita kwechigadzirwa.Medium-viscosity HPMC inogona kuvandudza michina yechigadzirwa, senge simba uye kusimba.Inokodzera putty poda inoda kuchengetedza mvura yakanaka uye kubatana.
3. High viscosity HPMC:
High viscosity HPMC inogona kuvandudza kukora uye anti-sag kuita kweputty poda.Inogonawo kuvandudza kuchengetwa kwemvura uye kusungirirwa kwekuita kwechigadzirwa.Yakakwira viscosity HPMC inogona kuvandudza michina yechigadzirwa, senge simba uye kusimba.Inokodzera putty poda inoda yakakwira thickening uye anti-sag performance.
mukupedzisa:
Cellulose ethers inoshandiswa zvakanyanya muindasitiri yekuvaka nekuda kwekunaka kwekuchengetedza mvura, kukora uye kusungirira zvivakwa.HPMC yave yakakurumbira cellulose ether muindasitiri yekuvaka nekuda kwehunhu hwayo hwakanaka.HPMC inouya mune zvakasiyana viscosities, kubva pasi kusvika kumusoro.Kushandiswa kwema cellulose ethers ane akasiyana viscosities anogona kuvandudza kushanda, kuseta nguva, thixotropic performance, kuchengetedza mvura, bonding performance uye mechanical properties yeputty powder.Kushandiswa kwe cellulose ethers kunogona kuvandudza kunaka uye kushanda kweputty powders, zvichiita kuti zvive zvakakodzera kune zvakasiyana-siyana zvinoshandiswa mumhizha yekuvaka.
