Mukugadzirwa kweputty powder, kuwedzera huwandu hwakakodzera hwe of Hydroxypropyl Methyl Cellulose (HPMC)inogona kuvandudza mashandiro ayo, zvakaita sekuvandudza rheology yeputty powder, kuwedzera nguva yekuvaka, uye kuwedzera kunamira. HPMC chinhu chinowanzo shandiswa mukuwedzera kukora uye kugadzirisa, chinoshandiswa zvakanyanya muzvinhu zvekuvaka, machira, manamatisi nedzimwe nzvimbo. Kune putty powder, kuwedzera HPMC hakungogone kuvandudza mashandiro ekuvaka chete, asiwo kusimudzira kugona kwekuzadza uye kushanda kweputty kudzivirira kutsemuka.

 

Basa rehydroxypropyl methylcellulose
Kuvandudza kuyerera kwemvura uye mashandiro ekuvaka: HPMC ine simba rakanaka rekukora, izvo zvinogona kuvandudza kuyerera kweputty powder, zvichiita kuti putty powder ive yakafanana uye isanyanya kuyerera kana ikashandiswa uye yagadziriswa, uye inovandudza kushanda zvakanaka uye kunaka kwekuvaka.

 

Kuwedzera kunamira: Kuwedzerwa kweHPMC kunogona kuvandudza kunamira pakati pehupfu hweputty nezvinhu zvepasi, zvichidzivirira matambudziko akadai sehupfu hweputty hunodonha uye hunotsemuka.

 

Kuvandudza kuchengetwa kwemvura: HPMC inogona kuwedzera kuchengetwa kwemvura muputty powder, kuderedza mwero wekubuda kwemvura, nokudaro ichidzivirira putty kuti isaome kana kutsemuka, uye ichibatsira putty kuti irambe yakafanana panguva yekuomeswa.

 

Kudzivirira kutsemuka kwematombo: Maumbirwo epolymer eHPMC anogona kuvandudza kuchinjika kweputty powder uye kuderedza kutsemuka kunokonzerwa nekutsemuka, kushanduka kwetembiricha kana kushanduka kwehwaro.

 

Huwandu hweHydroxypropyl Methylcellulose Hwakawedzerwa
Kazhinji, huwandu hwehydroxypropyl methylcellulose inowedzerwa hunowanzova pakati pe0.3% ne1.5% yehuremu hwese hweputty powder, zvichienderana nerudzi rweputty powder inoshandiswa, mashandiro anodiwa, uye zvinodiwa zvekushandisa.

 

Upfu hweputty hwakaderera: Kune mamwe mapoda eputty anoda kuyerera kuri nani, huwandu hwakaderera hweHPMC hunogona kushandiswa, kazhinji hunenge 0.3%-0.5%. Chinangwa cherudzi urwu rweputty powder ndechekuvandudza mashandiro ekuvaka uye kuwedzera nguva yekuvhura. HPMC yakawandisa inogona kukonzera kuti putty powder ive yakanyanya kusimba uye kukanganisa kuvaka.

 

Upfu hweputty hwakanyanya kusimba: Kana chinangwa chiri chekuwedzera kunamira uye kuramba kutsemuka kweputty, kana kuti madziro ane hunyoro hwakaoma (senzvimbo dzine hunyoro hwakawanda), huwandu hwakawanda hwekuwedzera hweHPMC hunogona kushandiswa, kazhinji 0.8%-1.5%. Chinangwa cheupfu hweputty idzi ndechekuvandudza kunamira, kuramba kutsemuka uye kuchengetedza mvura.

 

Hwaro hwekugadzirisa huwandu hwekuwedzera
Nzvimbo yekushandisa: Kana nzvimbo yekuvaka ine hunyoro hwakawanda kana tembiricha yakaderera, huwandu hweHPMC hunowedzerwa hunowanzo wedzerwa kuti huvandudze kuchengetedza mvura uye kushanda kwehupfu hweputty kunodzivirira kutsemuka.
Rudzi rweputty: Mhando dzakasiyana dzeputty powder (dzakadai se interior wall putty, exterior wall putty, fine putty, coarse putty, nezvimwewo) dzine zvinodiwa zvakasiyana zveHPMC. Fine putty inoda simba rakawanda rekukora, saka huwandu hweHPMC hunoshandiswa huchava hwakakwira; nepo pacoarse putty, huwandu hunowedzerwa hunogona kunge hushoma.
Mamiriro ehwaro: Kana hwaro hwacho hwakaomarara kana kuti huchinyungudutsa mvura zvakanyanya, zvingava zvakakosha kuwedzera huwandu hweHPMC hunowedzerwa kuti pave nekunamatira pakati peputty nehwaro.

 

Nzira dzekudzivirira pakushandisa HPMC

Dzivisa kuwedzera zvakanyanya: Kunyangwe HPMC ichigona kuvandudza mashandiro eputty powder, HPMC yakawanda ichaita kuti putty powder ive yakamanikana uye yakaoma kugadzira, uye inotokanganisa kumhanya kwekuomesa uye kuoma kwekupedzisira. Saka, huwandu hwekuwedzera hunofanira kudzorwa zvichienderana nezvinodiwa chaizvo.

 

Kusanganiswa nezvimwe zvinowedzerwa: HPMC inowanzo shandiswa pamwe chete nezvimwe zvinowedzerwa zvakaita sehupfu hwerabha, cellulose, nezvimwewo. Kana ikashandiswa pamwe chete nezvimwe zvinosimbisa kana zvinochengetedza mvura, kutarisirwa kunofanira kupihwa kune simba rekubatana pakati pavo kudzivirira kusawirirana kwekushanda.

 

Kugadzikana kwezvinhu:HPMCchinhu chinonyungudika mumvura. Kuwedzera zvakanyanya kunogona kukonzera kuti upfu hweputty hutore hunyoro uye huparare panguva yekuchengetera. Saka, panguva yekugadzira nekuchengetera, huwandu hweHPMC hunofanirwa kutariswa kuti ive nechokwadi chekuti upfu hweputty hwakagadzikana mumamiriro ekuchengetedza akajairika.

 

Kuwedzera HPMC muputty powder kunogona kuvandudza mashandiro ayo zvakanyanya, kunyanya maererano nekushanda kwekuvaka, kuchengetedza mvura uye kuramba kutsemuka. Kazhinji, huwandu hweHPMC hunowedzerwa huri pakati pe0.3% ne1.5%, iyo inogadziriswa zvichienderana nezvinodiwa nemarudzi akasiyana eputty powder. Paunenge uchiishandisa, zvakakosha kuti uenzanise simba rayo rekukora nezvinodiwa zvekuvaka kudzivirira migumisiro isina kufanira inokonzerwa nekushandiswa zvakanyanya.
