Putty poda chinhu chinowanzo shandiswa kuvaka, kunyanya kugadzirwa negypsum uye zvimwe zvinowedzera. Inoshandiswa kuzadza mapundu, seams uye kuputika mumadziro uye matenga. Hydroxypropylmethylcellulose (HPMC) imwe yezvinonyanya kushandiswa zvinowedzera mu putty powder. Iyo ine yakanakisa kuchengetedza kwemvura kuita uye yakanaka kunamatira, iyo inogona kuvandudza kushanda uye simba re putty. Nekudaro, iyo mhando yeHPMC cellulose inogona kukanganiswa nezvinhu zvakasiyana, senge agitation uye dilution.
Kukurudzira inhanho inokosha mukugadzirira kweputty powder. Inova nechokwadi chekuti zvese zvinoshandiswa zvakagovaniswa zvakaenzana uye kuti chigadzirwa chekupedzisira hachina mapundu uye zvimwe zvinokanganisa. Nekudaro, kushushikana kwakanyanya kunogona kutungamira kune yakashata mhando HPMC cellulose. Kunyanya kushungurudza kunogona kuita kuti cellulose iparare, ichideredza kuchengetedza kwayo mvura uye inonamira zvinhu. Nekuda kweizvozvo, iyo putty inogona kusanamatira zvakanaka kumadziro uye inogona kutsemuka kana kupeuka mushure mekushandisa.
Kuti udzivise dambudziko iri, zvakakosha kutevera mirairo yemugadziri wekusanganisa putty powder. Kazhinji, mirairo ichatsanangura huwandu hwakakodzera hwemvura uye nguva yekushungurudzika. Nenzira yakanaka, iyo putty inofanira kunyatsomutswa kuti iwane yakatsetseka uye inowirirana manyorerwo pasina kuputsa cellulose.
Kuonda chimwe chinhu chakakosha chinokanganisa kunaka kweHPMC cellulose mu putty powder. Dilution inoreva kuwedzera mvura kana zvimwe zvinonyungudutsa paputty kuti zvive nyore kupararira nekuvaka. Zvisinei, kuwedzera mvura yakawandisa kunoderedza cellulose uye kuderedza nzvimbo yayo yekuchengetedza mvura. Izvi zvinogona kuita kuti putty iome nekukurumidza, zvichikonzera kutsemuka uye shrinkage.
Kuti udzivise dambudziko iri, zvakakosha kutevedzera mirairo yemugadziri we diluting putty powder. Kazhinji, mirairo ichatsanangura huwandu hwakakodzera hwemvura kana solvent yekushandisa uye nguva yekusanganiswa. Zvinokurudzirwa kuwedzera mvura shoma zvishoma nezvishoma uye kusanganisa zvakanaka usati wawedzera. Izvi zvichava nechokwadi chekuti cellulose yakaparadzirwa zvakanaka muputty uye inochengeta zvinhu zvayo zvekuchengetedza mvura.
Kupfupisa, kubvongodza uye dilution kuchakanganisa kunaka kweHPMC cellulose mune putty poda. Zvakakosha kutevera mirairo yemugadziri zvakanyatsonaka kuti uve nechokwadi chokuti cellulose inochengetedza mvura-inochengetedza uye inonamatira zvinhu. Nekuita izvi, munhu anogona kuwana yemhando yepamusoro putty iyo inopa yakanakisa mhedzisiro uye inova nechokwadi chekunamatira kwenguva refu uye kusimba.
