Kuchengetwa kwemvura yehydroxypropyl methylcellulose ether
Kuchengetwa kwemvura yedry mix mortar zvinoreva kugona kwedhaka kubata nekukiya mvura.Iyo yakakwirira viscosity yehydroxypropyl methylcellulose ether, zviri nani kuchengetedza mvura.Nekuti iyo cellulose chimiro chine hydroxyl uye ether zvisungo, maatomu eokisijeni ari pahydroxyl uye ether bond mapoka anobatana nemamorekuru emvura kugadzira mabhondi ehydrogen, kuitira kuti mvura yemahara ive yakasungwa mvura uye inopinza mvura, nokudaro ichiita basa mukuchengetedza mvura.
Solubility yeHydroxypropyl Methyl Cellulose Ether
1. Coarse particle cellulose ether iri nyore kupararira mumvura pasina agglomeration, asi chiyero chekuparara chinononoka zvikuru.Cellulose ether iri pasi pe60 mesh inonyungudutswa mumvura kwemaminitsi makumi matanhatu.
2. Fine particle cellulose ether iri nyore kupararira mumvura pasina agglomeration, uye chiyero chekuparara chiri pakati nepakati.Cellulose ether pamusoro pe80 mesh inonyungudutswa mumvura kwemaminitsi matatu.
3. Ultra-fine particle cellulose ether inopararira nekukurumidza mumvura, inonyungudika nekukurumidza, uye inoita viscosity nekukurumidza.Cellulose ether pamusoro pe120 mesh inonyungudika mumvura kwemaminitsi gumi kusvika makumi matatu.
Iyo yakanyanya kunaka zvidimbu zvehydroxypropyl methylcellulose ether, zviri nani kuchengetedza mvura.Iyo pamusoro peiyo coarse-grained cellulose ether inonyungudika pakarepo mushure mekusangana nemvura uye inoita gel phenomenon.Nama inoputira zvinhu kudzivirira mamorekuru emvura kuti asarambe achipinda.Dzimwe nguva haigone kuparadzirwa zvakafanana uye kunyungudutswa kunyangwe mushure menguva refu yekubvongodza, ichigadzira cloudy flocculent solution kana agglomeration.Izvo zvakanaka zvimedu zvinopararira uye zvinonyungudika pakarepo mushure mekusangana nemvura kuti zvigadzire yunifomu viscosity.
PH kukosha kwehydroxypropyl methylcellulose ether (inononoka kana yekutanga simba mhedzisiro)
Iyo pH kukosha kwehydroxypropyl methylcellulose ether vagadziri kumba nekune dzimwe nyika inodzorwa zvakanyanya panenge 7, iyo iri mu acidic state.Nemhaka yekuti kuchine nhamba huru yeanhydroglucose ring structures mu molecular structure ye cellulose ether, iyo anhydroglucose ring ndiro boka guru rinokonzera kuderera kwe simenti.Mhete yeanhydroglucose inogona kugadzira calcium ions mu simenti hydration solution inogadzira shuga-calcium molecular compounds, kuderedza calcium ion concentration panguva yekupinza simende hydration, kudzivirira kuumbwa uye kunaya kwe calcium hydroxide uye calcium salt crystals, uye kunonotsa hydration. simende.process.Kana iyo PH kukosha iri mu alkaline state, dhaka richaonekwa mune yekutanga-simba mamiriro.Iye zvino mafekitari mazhinji anoshandisa sodium carbonate kugadzirisa iyo pH kukosha.Sodium carbonate imhando yekukurumidza kuseta agent.Sodium carbonate inovandudza kushanda kwepamusoro pemasimende, inosimudzira kubatana pakati pezvikamu, uye inowedzera kuvandudza viscosity yedhaka.Panguva imwecheteyo, sodium carbonate inokurumidza kusanganiswa ne calcium ions mudhaka kuti ikurudzire kuumbwa kwe ettringite, uye simenti inobata nokukurumidza.Naizvozvo, iyo pH kukosha kunofanirwa kugadziridzwa zvinoenderana nevatengi vakasiyana mune chaiyo yekugadzira maitiro.
Mhepo Inopinza Zvinhu zveHydroxypropyl Methyl Cellulose Ether
Mhepo-entraining mhedzisiro yehydroxypropyl methylcellulose ether inonyanya nekuti cellulose ether imhando yesurfactant.Basa remukati re cellulose ether rinonyanya kuitika pane gasi-liquid-solid interface.Kutanga, kuiswa kwemhepo inoputika, inoteverwa nekupararira uye Wetting effect.Cellulose ether ine maalkyl mapoka, ayo anoderedza zvakanyanya kudhonzerana kwepasi uye kupindirana kwesimba remvura, zvichiita kuti zvive nyore kugadzira maturu madiki akavharika panguva yekuzunguza kwemushonga wemvura.
Gel Properties yeHydroxypropyl Methyl Cellulose Ether
Mushure mekunge hydroxypropyl methylcellulose ether yanyungudutswa mudhaka, methoxyl uye hydroxypropyl mapoka ari pa molecular chain achaita ne calcium ions uye aluminium ions mu slurry kuumba gel viscous uye kuzadza simende dhaka risina chinhu., kuvandudza kuumbwa kwedhaka, kutamba basa rekuzadza nekusimbisa.Nekudaro, kana iyo composite matrix iri pasi pekumanikidzwa, iyo polima haigone kutamba yakasimba kutsigira basa, saka iyo simba uye kupeta reshiyo yedhaka inodzikira.
Firimu Kugadzirwa kweHydroxypropyl Methyl Cellulose Ether
Mushure mekunge hydroxypropyl methyl cellulose ether yawedzerwa kuti hydration, chidimbu chitete chelatex firimu chinoumbwa pakati pemasimende.Iyi firimu ine chisimbiso chekuita uye inovandudza kuoma kwepamusoro kwedhaka.Nekuda kwekuchengetwa kwemvura kwakanaka kwehydroxypropyl methylcellulose ether, mamorekuru emvura akakwana anochengetwa mukati medhaka, nekudaro kuve nechokwadi chekuomarara kwesimende uye kukura kwakazara kwesimba, kuvandudza kusimba kwechisungo chedhaka, uye panguva imwechete Iyo. inovandudza kubatanidzwa kwedhaka, inoita kuti dhaka rive nepurasitiki yakanaka uye kushanduka, uye inoderedza kuderera uye deformation yedhaka.
