Basa reHPMCmuhari yakanyorova
Dhaka rakasanganiswa rakanyorova: Dhaka rakasanganiswa imhando yesimende, musanganiswa wakatsetseka, musanganiswa nemvura, uye zvichienderana nehunhu hwezvinhu zvakasiyana-siyana, mune imwe chiyero, mushure mekuyerwa panzvimbo yekusanganisa, rinosanganiswa, roendeswa kunzvimbo inoshandiswa nerori, mumudziyo wakatsaurirwa wekuchengetera, uye rinoshandiswa munguva yakatarwa musanganiswa wakanyorova wapera.
Hydroxypropyl methyl cellulose inoshandiswa senzira yekuchengetedza mvura yesimbi yesimbi, kupomba simbi yesimbi inodzoreredza mvura. Mu gypsum senzira yekubatanidza mvura kuti ivandudze kushandiswa kwayo uye kuwedzera nguva yekushanda, hydroxypropyl methylcellulose HPMC inochengetedza mvura kuitira kuti slurry mushure mekuomeswa isanyanya kukurumidza uye kutsemuka, zvichiita kuti simba riwedzere. Kuchengetedza mvura chinhu chakakosha chehydroxypropyl methyl cellulose HPMC, uye inyaya yevagadziri vesimbi yakawanda inonyorova. Zvinhu zvinokanganisa mhedzisiro yekuchengetedza mvura yesimbi inonyorova zvinosanganisira huwandu hweHPMC yakawedzerwa, viscosity yeHPMC, kupfava kwezvikamu uye tembiricha yenzvimbo inoshandiswa.
Hydroxypropyl methyl cellulose HPMC iri mudhaka rakanyorova ine basa guru muzvikamu zvitatu, chimwe chazvo kugona kwayo kubata mvura, chechipiri kugona kwayo kubata mvura zvakanaka uye thixotropy, chechitatu ndechekubatana kwayo nesimende. Kuchengetwa kwemvura neCellulose ether kunoenderana nekuwanda kwemvura iri mudhaka, kuumbwa kwedhaka rakanyorova, ukobvu hwedhaka rakanyorova, kudiwa kwemvura, nenguva yekuiswa. Kana hydroxypropyl methyl cellulose ikanyanya kujeka, kuchengetedza mvura kuri nani.
Zvinhu zvinokanganisa kuchengetwa kwemvura mudhaka rakanyorova zvinosanganisira kusimba kwe cellulose ether, kuwedzera huwandu, saizi yezvidimbu uye tembiricha. Kusimba kwe cellulose ether kwakakura, kusimba kwemvura kunowedzerawo. Kusimba kwemvura chinhu chakakosha pakushanda kweHPMC. Pachigadzirwa chimwe chete, kushandisa nzira dzakasiyana kuyera kusimba kwemhedzisiro kunosiyana zvakanyanya, dzimwe dzichitosvika pachikamu chimwe chete. Saka, kuenzanisa kusimba kwemvura kunofanirwa kuitwa nenzira imwe chete yekuyedza, kusanganisira tembiricha, rotor, nezvimwewo.
Kazhinji, kana viscosity yakakwira, ndipo panowanikwawo mvura yakawanda. Zvisinei, kana viscosity yakakwira, HPMC inowedzera huremu hwemamorekuru, uye HPMC inonyungudika zvishoma, 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 inonamira zvakanyanya, mashandiro akanaka ekuvaka, mashandiro ekukwenya viscous uye kunamatira kwakanyanya kune substrate. Zvisinei, kuvandudzwa kwesimba rekuvaka remortar yakanyorova pachayo hakuna kubatsira. Zvese zviri zviviri, mashandiro haasi pachena ekurwisa kusungirirwa. Kusiyana neizvi, mamwe viscosity yepakati nepasi asi yakagadziriswa hydroxypropyl methylcellulose ine mashandiro akanaka mukuvandudza simba rekuvaka remortar yakanyorova.
Kana huwandu hwe cellulose ether PMC wet mortar hwakawedzerwa hwakawanda, kuchengetedza mvura kuri nani, viscosity iri nani, kuchengetedza mvura kuri nani. Kupfava zvakare chiratidzo chakakosha chekushanda kwehydroxypropyl methyl cellulose.
Kupfava kwehydroxypropyl methyl cellulose kunewo simba pakuchengetedza mvura. Mumamiriro ezvinhu akajairwa, viscosity yakafanana uye kupfava kwakasiyana kwehydroxypropyl methyl cellulose, pasi pehuwandu hwakafanana hwekuwedzera, kupfava kwekuchengetedza mvura kudiki kuri nani.
Mudhaka rakanyorova, kuwedzerwa kwe cellulose etherHPMCyakaderera zvikuru, asi inogona kuvandudza mashandiro ekuvaka kwedhaka rakanyorova, ndicho chinhu chikuru chinokanganisa mashandiro edhaka. Mashandiro edhaka rakanyorova anokanganiswa zvikuru nekusarudza kwakakodzera kwehydroxypropyl methyl cellulose.
