HPMC (hydroxypropyl methylcellulose) chinhu chakakosha chinoshandiswa zvakanyanya mukuvaka zvinhu zvakaita seputty powder, coatings, glues, nezvimwewo. Chine mabasa akawanda akadai sekukora, kuchengetedza mvura, uye kuvandudza mashandiro ekuvaka. Mukugadzira putty powder, kuwedzerwa kweHPMC hakungogone chete kuvandudza kuchengetedza mvura kwechigadzirwa, asiwo kuwedzera nguva yekuvaka, kudzivirira putty kuti isaome nekukurumidza panguva yekuvaka, uye kukanganisa mhedzisiro yekuvaka.
1. Sarudza modhi yeHPMC yakakodzera
Kushanda kweHPMC kwakabatana zvakanyanya nehuremu hwayo hwemamorekuru, kutsiva kwehydroxypropyl, kutsiva kwemethyl nezvimwe zvinhu. Kuti uvandudze kuchengetwa kwemvura kweputty powder, tanga wasarudza modhi yakakodzera yeHPMC.
Kusviba kwakanyanya HPMC: HPMC ine huremu hwakawanda inogona kuumba network yakasimba, iyo inobatsira kuvandudza kuchengetwa kwemvura kweputty powder uye kudzivirira kuputika kwemvura nguva isati yakwana. Kazhinji, HPMC ine kusviba kwakanyanya ichave nemhedzisiro yakanaka pakukwanisa kuchengetedza mvura.
Mwero wakakodzera wekutsiva: Kutsiva kwehydroxypropyl nekutsiva kwemethyl kweHPMC zvinokanganisa kunyungudika kwayo uye kugona kwayo kuchengetedza mvura. Mwero wakakwira wekutsiva kwehydroxypropyl unobatsira kuvandudza hydrophilicity yeHPMC, nokudaro zvichiwedzera mashandiro ayo ekuchengetedza mvura.
Zvichienderana nezvinodiwa neputty powder, kusarudza HPMC modhi yakakodzera kunogona kuvandudza zvakanyanya mwero wekuchengetedza mvura kwechigadzirwa.
2. Wedzera huwandu hweHPMC hwakawedzerwa
Kuti pave nekuwedzera kuchengetwa kwemvura kweputty powder, huwandu hweHPMC inowedzerwa hunogona kuwedzerwa zvakakodzera. Nekuwedzera huwandu hweHPMC, kupararira kwayo muputty kunogona kuvandudzwa zvinobudirira uye kugona kwayo kuchengetedza mvura kunogona kuvandudzwa.
Kuwedzera kwehuwandu hwekuwedzera kuchaitawo kuti putty powder iwedzere kusimba. Saka, zvakakosha kuchengetedza mvura zvakanaka uku uchidzivirira kusimba kwakanyanya kuti zvikanganise mashandiro ekuvaka.
3. Kugadzira fomura zvine musoro
Kugadzirwa kwefomura yeputty powder kunokanganisa zvakananga kuchengetwa kwemvura kwayo. Pamusoro peHPMC, kusarudzwa kwezvimwe zvikamu mufomura (senge zvinozadza, zvinonamira, nezvimwewo) kuchakanganisawo kuchengetwa kwemvura kweputty powder.
Kupfava uye nzvimbo chaiyo yepamusoro: Saizi yezvikamu uye nzvimbo chaiyo yepamusoro ye.Chinozadza chiri muputty powder chinokanganisa kunyudzwa kwemvura. Upfu hwakatsetseka uye zvinozadza zvine nzvimbo yakakwira zvinogona kunyudza mvura zviri nani uye kuderedza kurasikirwa nemvura. Nokudaro, kusarudza zvine musoro saizi yezvidimbu zvefiller chinhu chakakosha mukuvandudza kuchengetwa kwemvura.
Kusarudzwa kwezvinoshandiswa nesimende: Kana putty powder iine simende nezvimwe zvinoshandiswa, hydration reaction yesimende inogona kutora mvura. Nokudaro, zvakakosha kugadzirisa kuchengetedza mvura yeputty nekugadzirisa chiyero chesimende kune filler.
4. Dzora maitiro ekusanganisa
Maitiro ekusanganisa anewo mhedzisiro yakati kuti pakuchengetwa kwemvura kweputty powder. Kusanganisa zvine mwero kunogona kubatsira HPMC kupararira zvizere uye kusanganiswa zvakaenzana nezvimwe zvinoshandiswa kudzivirira mutsauko mukuchengetwa kwemvura kunokonzerwa nekusanganiswa kusina kuenzana.
Nguva yakakodzera yekusanganisa nekumhanya: Kana nguva yekusanganisa iri pfupi, HPMC inogona kusanyungudutswa zvizere, izvo zvinokanganisa mashandiro ayo ekuchengetedza mvura. Kana kumhanya kwekusanganisa kwakanyanya, mhepo yakawandisa inogona kuiswa, zvichikanganisa kunaka kweputty powder. Saka, kudzora zvine musoro maitiro ekusanganisa kuchabatsira kuvandudza kuchengetedza mvura kweputty powder.
5. Dzora hunyoro nekupisa kwezvakatipoteredza
Kuchengetwa kwemvura kweputty powder hakungobatanidzwi nezvinhu zvakagadzirwa uye fomura chete, asiwo kwakabatana nehunyoro nekupisa kwenzvimbo yekuvaka. Munzvimbo ine tembiricha yakakwira uye hunyoro hushoma, hunyoro hweputty powder huri nyore kupwanyika, zvichiita kuti iome nekukurumidza uye inokanganisa mhedzisiro yekuvaka.
Munguva yekuvaka, mamiriro ekupisa nekunyorova akakodzera anofanira kuchengetedzwa zvakanyanya sezvinobvira kudzivirira kuti putty powder isarasike mvura nekukurumidza. Kudzora tembiricha yemhepo nekunyorova kwakakodzera kunogonawo kuvandudza kuchengetwa kwemvura kweputty powder.
6. Wedzera chinhu chinochengetedza mvura
Pamusoro peHPMC, zvimwe zvinhu zvinochengetedza mvura zvinogonawo kunzi zvinowedzerwa kuputty powder, zvakaita semamwe mapolymer, polyvinyl alcohol, nezvimwewo. Izvi zvinhu zvinochengetedza mvura zvinogona kuwedzera kuchengetedza mvura kweputty, kuwedzera nguva yekuvaka, uye kudzivirira putty kuti isaome uye isatsemuke nekukurumidza.
Zvisinei, kana muchiwedzera zvinhu zvinochengetedza mvura, zvakakosha kuti mucherechedze kuti zvinoenderana sei neHPMC kuitira kuti pasave nemhedzisiro yakaipa kana kukanganisa mashandiro eputty pakuvaka.
7. Shandisa tekinoroji yekudzora hunyoro
Mune dzimwe nguva dzakakosha, tekinoroji yekudzora hunyoro inogona kushandiswa kuwedzera kuchengetedza mvura yeputty powder. Semuenzaniso, kushandiswa kwemvura-based sealing membranes kana michina yehunyoro kunogona kuderedza kurasikirwa nemvura kweputty panguva yekuvaka, kuchengetedza hunyoro hweputty layer, nokudaro kuwedzera nguva yekuvaka kwayo uye kuvandudza kuchengetedza mvura.
Kuchengetwa kwemvura kweputty powder kunogona kuvandudzwa zvinobudirira nekusarudza mhando chaiyo yeHPMC, kuwedzera huwandu hwekuwedzera, kugadzirisa fomura, kuvandudza maitiro ekusanganisa, kudzora hunyoro nekupisa kwenzvimbo yekuvaka, nezvimwe zviyero. Sechikamu chakakosha cheputty powder, kuvandudzwa kwekuchengetedza mvura kweHPMC hakugone kungovandudza kushanda kwekuvaka chete, asiwo kuvandudza mhando yekupedzisira yekuvaka uye kuderedza zvikanganiso nematambudziko mukuvaka. Naizvozvo, kunzwisisa nekuziva nzira idzi dzekuvandudza mwero wekuchengetedza mvura kwakakosha zvikuru kumabhizinesi anogadzira nekushandisa putty powder.
