1.Wet yakavhenganiswa dhiri.
2.Hydroxyprondyopropyl methyl cellel cellulose inoshandiswa seyemvura-yekuchengetedza mumiririri weiyo coment motsi uye kudzoreredza moter. Panyaya yeGypsum seyekusimudzira kuti uvandudze nguva uye kuwedzera nguva yekushanda, iyo Kuchengeta kwemvura kunotadzisa iyo slapry kubva mukupaza nekukurumidza mushure mekuoma, uye inovandudza simba rapedza. Kuchengetwa kwemvura inzvimbo yakakosha ye hydroxypropyl methyl cellel Zvinhu zvinokonzeresa kudzokorora kwemvura kwemvura yekunyoroveswa-yakasanganiswa
3.Mukuru mabasa eHydroxyPropyl methyl Celler Cellyl Cellyl inonyanya kuita zvinhu, imwe yacho ndiyo pesvedzero yekuwirirana uye yeTixotropy yemutungamiriri, uye yechitatu kudyidzana neiyo simende. Kuchengetwa kwemvura kwemvura ether kunoenderana nemvura yekubatira kwemvura yeiyo chigadziko, kuumbwa kwerukova, iko ukobvu hwembeu, iyo mvura yekuda kwemvura, uye nguva yekugara. Iyo yepamusoro iyo transnency ye hydroxyprusyl methyl cellelose, zvirinani kuchengetwa kwemvura.
4.Factors anokanganisa kuchengetwa kwemvura kwemvura yekunyoroveswa-yakavhenganiswa inosanganisira cellulose etter viscosity, kuwedzera huwandu, temberi saizi uye tembiricha. Iyo yakakura iyo visikopa yemasero e cellulose ether, zvirinani kuchengetwa kwemvura. Viscosity izimendi yakakosha yeHPMC kuita. Nezve chigadzirwa chimwe chete, mhedzisiro yekushandisa nzira dzakasiyana kuti dziyedze vhiza dzinosiyana zvakanyanya, uye vamwe vakatove nemhepo mbiri. Naizvozvo, kuenzanisa kwe viscosity kunofanirwa kuitwa nenzira imwecheteyo bvunzo, kusanganisira tembiricha, spindle, nezvimwe.
5.Genezviti kutaura, yakakwira iyo viscosity, zvirinani kuchengetwa kwemvura. Nekudaro, iyo yepamusoro iyo viscosity, yakakwira iyo smecular uremu hweHPMC uye yakaderera iyo solubility yeHPMC, iyo ine kukanganisa kwakashata pane simba rekugadzira. Yakakwira iyo viscosity, zvakanyatsojeka mhedzisiro yemota, asi haina hukama zvakananga. Iyo yepamusoro iyo viscosity, iyo yakawanda viscous iyo dhizaini yakanyorova, zviri nani kuita kwekuvaka, kuita kweiyo viscous scriper uye yakakwira kuendeswa kune substrate. Nekudaro, simba rakawedzera rerudzi rwemutya rakanyorova pacharo haribatsire. Mafungiro maviri aya haana kuoneka anti-sag kuita. Mukupesana, imwe yepakati uye yakaderera viscosity asi yakagadziridzwa hydroxypropropyl methyl cellown ine maitiro akanaka mukuvandudza simba rerudzi rwemutengesi.
6.Kukukura huwandu hwe cellulose ether yakawedzerwa kune hpmc yakanyorova mongwe, zviri nani kuchengetwa kwemvura, uye yakakwira viscosity, zvirinani kuchengetwa kwemvura. Fineness zvakare ndiyo yakakosha performance index ye hydroxyprupyl methyl cellulose.
7.Kuita kwakawanda kwehydroxyprupyl methyl cellelose ine imwe pesvedzero pakuchengeta kwayo kwemvura. Kazhinji, yeHydroxyPropyl methyl methyl cellelose neiyo viscosity uye yakasiyana-fiki, iyo diki iyo yakajeka, iyo madiki ekuchengetwa kwemvura pasi pehuwandu hwekuwedzera. zviri nani.
8.Inet-yakasanganiswa murayo, iyo yekuwedzera mari yeCellulose Ether HPMC yakaderera, asi inogona kuvandudza zvakanyanya basa rekuvaka remvura, uye ndiyo huru yekuwedzera iyo inonyanya kukanganisa kuita kwemutumbi. Kusarudzwa zvine musoro kwehydroxyprupyl methyl cellelose, kuita kwekutya kwemvura kwakasimba.
