1. Dhaka rakasanganiswa rakanyorova: Dhaka rakasanganiswa rudzi rwesimende, dhaka rakasanganiswa, rakasanganiswa nemvura, uye zvichienderana nehunhu hwezvinhu zvakasiyana-siyana, zvichienderana nechiyero chakati, mushure mekuyerwa panzvimbo yekusanganisa, rakasanganiswa, rakatakurwa kuenda kunzvimbo inoshandiswa rori, uye rakaiswa mune yakakosha. Chengeta mudziyo uye shandisa musanganiswa wakanyorova wapera kwenguva yakatarwa.
2. Hydroxypropyl methyl cellulose inoshandiswa senzira yekuchengetedza mvura yesimbi yesimbi uye inodzoreredza kupomba simbi. Kana gypsum ichishanda senzira yekuwedzera kushanda kwayo uye kuwedzera nguva yekushanda, kuchengetedza mvura kweHPMC kunodzivirira slurry kuti isatsemuke nekukurumidza mushure mekuoma, uye kunovandudza simba mushure mekuoma. Kuchengetedza mvura chinhu chakakosha chehydroxypropyl methyl cellulose HPMC, uye inyaya yemakambani akawanda ekugadzira simbi yesimbi yemumba. Zvinhu zvinokanganisa kuchengetedza mvura yesimbi yesimbi yesimbi yakasanganiswa zvinosanganisira huwandu hweHPMC yakawedzerwa, viscosity yeHPMC, kupfava kwezvikamu uye tembiricha yenzvimbo yekushandisa.
3. Mabasa makuru ehydroxypropyl methyl celluloseHPMCMudhaka rakasanganiswa nemvura, pane zvinhu zvitatu zvinonyanya kuoneka, chimwe chacho kugona kubata mvura zvakanaka, chimwe chacho ndechekuita kuti dhaka rakasanganiswa nemvura rirambe rakafanana uye richishanda zvakanaka, uye chechitatu ndechekubatana nesimende. Kuchengetwa kwemvura kwe cellulose ether kunoenderana nekuwanda kwemvura yehwaro, kuumbwa kwedhaka, ukobvu hwedhaka, kudiwa kwemvura kwedhaka, uye nguva yekuiswa. Kana hydroxypropyl methyl cellulose ikanyanya kujeka, kuchengetedza mvura kunowedzerawo kunaka.
4. Zvinhu zvinokanganisa kuchengetwa kwemvura kwemortar yakasanganiswa nemvura zvinosanganisira kutaridzika kwe cellulose ether, huwandu hwekuwedzera, saizi yezvikamu uye tembiricha. Kutaridzika kukuru kwe cellulose ether, ndiko kutaridzika kwakanaka kwekuchengetedza mvura. Kutaridzika kwemvura chinhu chakakosha pakushanda kweHPMC. Pachigadzirwa chimwe chete, mhedzisiro yekushandisa nzira dzakasiyana kuyera kutaridzika kwemvura inosiyana zvakanyanya, uye dzimwe dzine mukaha wakapetwa kaviri. Saka, kuenzanisa kutaridzika kwemvura kunofanirwa kuitwa nenzira imwe chete yekuyedza, kusanganisira tembiricha, spindle, nezvimwewo.
5. Kazhinji, kana viscosity yakakwira, kuchengetedza mvura kuri nani. Zvisinei, kana viscosity yakakwira, huremu hwemamorekuru hweHPMC hwakakwira uye kunyungudika kweHPMC kwakaderera, izvo zvine mhedzisiro yakaipa pakusimba uye mashandiro ekuvaka kwemortar. Kana viscosity yakakwira, mhedzisiro yekukora kwemortar iri pachena, asi haina hukama zvakananga. Kana viscosity yakakwira, mortar yakanyorova yakawanda, mashandiro ekuvaka ari nani, mashandiro eviscous scraper uye kunamatira kwakakwira kune substrate. Zvisinei, kuwedzera kwesimba rekuvaka remortar yakanyorova pachayo hakubatsiri. Magadzirirwo maviri aya haana mashandiro akajeka ekudzivirira kusadzika. Kusiyana neizvi, mamwe viscosity yepakati nepasi asi yakagadziriswa hydroxypropyl methyl cellulose ine mashandiro akanaka mukuvandudza simba rekuvaka remortar yakanyorova.
6. Kana huwandu hwe cellulose ether hukawedzerwa mu HPMC wet mortar hwakakura, kuchengetedza mvura kunowedzera, uye viscosity yakakwira, kuchengetedza mvura kunowedzerawo. Kupfava zvakare chiratidzo chakakosha chekushanda kwe hydroxypropyl methyl cellulose.
7. Kupfava kwehydroxypropyl methyl cellulose kunewo simba pakuchengetedza mvura. Kazhinji, kune hydroxypropyl methyl cellulose ine viscosity yakafanana uye fineness yakasiyana, kupfava kudiki, mhedzisiro yekuchengetedza mvura idiki pasi pehuwandu hwakafanana hwekuwedzera. Zviri nani.
8. Mudhaka rakasanganiswa nemvura, huwandu hwekuwedzera hwe cellulose ether HPMC hwakaderera zvikuru, asi hunogona kuvandudza mashandiro edhaka rakanyorova, uye ndicho chinhu chikuru chinokanganisa mashandiro edhaka. Kana dhaka rakanyorova rikasarudzwa zvakanaka, mashandiro edhaka rakanyorova anokanganiswa zvikuru.
