Mukugadzirwa kweputty poda, kuwedzera huwandu hwakakodzera of Hydroxypropyl Methyl Cellulose (HPMC)inogona kuvandudza kushanda kwayo, sekuvandudza rheology yeputty powder, kuwedzera nguva yekuvaka, uye kuwedzera kunamatira. HPMC ndeye yakajairika thickener uye modifier, inoshandiswa zvakanyanya mukuvaka zvinhu, machira, anonamira uye mamwe minda. Kune putty poda, kuwedzera HPMC hakungogone kuvandudza mashandiro ekuvaka, asi zvakare kuwedzera huwandu hwekuzadza uye anti-kupaza kuita kweputty.

 

Basa rehydroxypropyl methylcellulose
Kuvandudza fluidity uye basa rekuvaka: HPMC ine yakanaka thickening effect, iyo inogona kuvandudza fluidity ye putty powder, zvichiita kuti putty powder iwedzere kufanana uye isinganyanyi kuyerera kana yakashandiswa uye yakagadziriswa, nekuvandudza kushanda uye kunaka kwekuvaka.

 

Kuwedzera kunamatira: Kuwedzerwa kweHPMC kunogona kuvandudza kunamatira pakati peputty powder uye nheyo yezvinhu, kudzivisa matambudziko akadai seputty powder inodonha uye kuputika.

 

Kuvandudza kuchengetwa kwemvura: HPMC inogona kuwedzera kuchengetwa kwemvura yeputty poda, inonoke kuyerera kwemvura, nekudaro ichidzivirira iyo putty kubva pakuoma uye kuputika, uye kubatsira iyo putty kuchengetedza kufanana panguva yekuomesa.

 

Enhanced crack resistance: Iyo polymer chimiro cheHPMC inogona kuvandudza kuchinjika kweputty poda uye kuderedza kuputika kunokonzerwa nekutsemuka, shanduko yekushisa kana deformation yechigadziko.

 

Huwandu hweHydroxypropyl Methylcellulose Yakawedzerwa
Kazhinji kutaura, huwandu hwehydroxypropyl methylcellulose yakawedzerwa inowanzova pakati pe0.3% ne1.5% yehuremu hwose hweputty powder, zvichienderana nerudzi rweputty powder inoshandiswa, kushanda kunodiwa, uye zvinodiwa zvekushandiswa.

 

Low viscosity putty poda: Kune mamwe putty poda inoda mvura iri nani, yakaderera HPMC yekuwedzera huwandu inogona kushandiswa, kazhinji yakatenderedza 0.3% -0.5%. Chinangwa cherudzi urwu rweputty powder ndechekuvandudza kushanda kwekuvaka uye kuwedzera nguva yakazaruka. Yakawandisa HPMC inogona kukonzera iyo putty poda kuti ive yakanyanya viscous uye inokanganisa kuvaka.

 

Yakakwirira viscosity putty powder: Kana chinangwa chiri chekusimudzira kunamatira uye kutsemuka kuramba kweputty, kana kumadziro ane yakaoma base kurapwa (zvakadai semhoteredzo dzine humidity yakakwirira), yakakwira HPMC yekuwedzera mari inogona kushandiswa, kazhinji 0.8% -1.5%. Chinangwa cheiyi putty powders ndechekuvandudza kunamatira, kutsemuka kuramba uye kuchengetedza mvura.

 

Nheyo yekugadzirisa huwandu hwekuwedzera
Shandisa nharaunda: Kana nzvimbo yekuvaka ine humidity yakakwira kana kuderera kwekushisa, huwandu hweHPMC hunowedzerwa hunowanzo wedzera kuvandudza kuchengetwa kwemvura uye anti-cracking performance ye putty powder.
Putty type: Mhando dzakasiyana dzeputty powder (zvakadai semukati madziro putty, kunze kwemadziro putty, fine putty, coarse putty, nezvimwewo) zvine zvakasiyana zvinodiwa zveHPMC. Fine putty inoda kuwedzera kukora mhedzisiro, saka huwandu hweHPMC hunoshandiswa huchakwira; nepo coarse putty, mari yakawedzerwa inogona kunge iri shoma.
Base mamiriro: Kana hwaro hwakakasharara kana kunyura kwakasimba kwemvura, zvingave zvakakosha kuwedzera huwandu hweHPMC hwakawedzerwa kuti uwedzere kunamatira pakati peputty nechigadziko.

 

Kungwarira pakushandisa HPMC

Dzivisa kuwedzera kuwedzera: Kunyange zvazvo HPMC inogona kuvandudza kushanda kweputty powder, yakawandisa HPMC ichaita kuti putty powder iwedzere kutaridzika uye yakaoma kuvaka, uye kunyange kukanganisa kuoma kwekuoma uye kuoma kwekupedzisira. Nokudaro, kuwanda kwekuwedzera kunoda kudzorwa maererano nezvinodiwa chaizvo.

 

Kusanganiswa nezvimwe zvinowedzera: HPMC inowanzoshandiswa pamwe chete nezvimwe zvinowedzera zvakadai serubha powder, cellulose, etc. Kana ikashandiswa pamwe chete nemamwe makobvu kana kuchengetedza mvura, kutarisa kunofanira kubhadharwa kune synergistic effect pakati pavo kudzivisa kukakavara kwekuita.

 

Material kugadzikana:HPMCchinhu chinonyungudika nemvura. Kuwedzera kwekuwedzera kunogona kukonzera iyo putty poda kuti itore unyoro uye iparare panguva yekuchengetedza. Nokudaro, panguva yekugadzira nekuchengetedza, huwandu hweHPMC hunoshandiswa hunofanira kuonekwa kuti huve nekugadzikana kweputty powder pasi pemamiriro ezvinhu ekuchengetedza.

 

Kuwedzera HPMC kune putty poda inogona kuvandudza zvakanyanya mashandiro ayo, kunyanya maererano nekuita kwekuvaka, kuchengetedza mvura uye kushomeka kuramba. Kazhinji kutaura, huwandu hwekuwedzera hweHPMC huri pakati pe0.3% ne1.5%, iyo inogadziriswa maererano nezvinodiwa zvemhando dzakasiyana dzeputty powder. Paunenge uchiishandisa, zvinodikanwa kuenzanisa mhedzisiro yayo yekukora nezvinodiwa zvekuvaka kuti udzivise zvisingakoshi zvinokonzerwa nekushandisa zvakanyanya.
