Hydroxypropyl methylcelluloseHPMCisiri-ionic cellulose ether yakagadzirwa kubva kune yakasikwa polymer material cellulose kuburikidza nekutevedzana kwemakemikari kugadzirisa.Ihwo hupfu huchena husinganhuhwi, husina muchetura uye husina chepfu hunozvimba mumvura inotonhora kusvika kune yakajeka kana kuti zvishoma yakasviba colloidal solution.Iyo ine maitiro ekukora, kusunga, kuparadzira, emulsifying, firimu-kuumba, kumisa, adsorbing, gelling, pamusoro-inoshanda, kuchengetedza unyoro uye inodzivirira colloid.Hydroxypropyl methylcellulose, methylcellulose inogona kushandiswa mukuvaka zvinhu, coating indasitiri, synthetic resin, Ceramic indasitiri, mushonga, chikafu, machira, kurima, makemikari ezuva nezuva uye mamwe maindasitiri.
Iyo yekuchengeta mvura mhedzisiro uye musimboti wehydroxypropyl methylcellulose HPMC
Cellulose ether HPMC inonyanya kuita basa rekuchengetedza mvura uye kukora mune simende dhaka uye gypsum-based slurry, iyo inogona kunyatso kuvandudza kubatana uye sag kuramba kwe slurry.
Zvinhu zvakadai sekushisa kwemhepo, tembiricha uye kudzvinyirirwa kwemhepo zvinokanganisa mwero wekuvhuvhuta kwemvura mudhaka resimende uye zvigadzirwa zvegypsum.Naizvozvo, mumwaka wakasiyana, kune mimwe misiyano mukuchengetedza mvura mhedzisiro yezvigadzirwa zvine huwandu hwakafanana hweHPMC yakawedzerwa.Mukuvaka chaiko, iyo yekuchengeta mvura mhedzisiro yeslurry inogona kugadziriswa nekuwedzera kana kudzikisa huwandu hweHPMC hwakawedzerwa.Kuchengetwa kwemvura kwemethyl cellulose ether pakupisa kwepamusoro chiratidzo chakakosha chekusiyanisa kunaka kwemethyl cellulose ether.Yakanakisa HPMC yakatevedzana zvigadzirwa zvinogona kunyatsogadzirisa dambudziko rekuchengetedza mvura pasi pekushisa kwakanyanya.Mumwaka wekushisa kwakanyanya, kunyanya munzvimbo dzinopisa uye dzakaoma uye dzakatetepa-layer kuvakwa padivi rezuva, yemhando yepamusoro HPMC inodiwa kuvandudza kuchengetwa kwemvura kweslurry.Yepamusoro-soro HPMC, ine kufanana kwakanaka kwazvo, mapoka ayo methoxy uye hydroxypropoxy akagoverwa zvakaenzana pamwe chete ne cellulose molecular chain, iyo inogona kuvandudza kugona kwemaatomu eokisijeni pane hydroxyl uye ether zvisungo kuti zvibatane nemvura kuti zvigadzire mabhondi ehydrogen , kuitira kuti mvura yakasununguka inova yakasungwa mvura, kuitira kuti inyatso kudzora kubuda kwemvura kunokonzerwa nekupisa kwemamiriro ekunze uye kuwana mvura yakakwirira yekuchengetedza.
High-quality cellulose HPMC inogona kuparadzirwa zvakafanana uye inobudirira mumatope esimende uye gypsum-based products, uye inoputira zvikamu zvose zvakasimba, uye inoumba firimu rekunyorova, uye hunyoro huri mujinga hunobudiswa zvishoma nezvishoma kwenguva yakareba.Iyo hydration reaction yeiyo coagulating zvinhu inoitika, nekudaro kuve nechokwadi chekubatana kwesimba uye kumanikidza kusimba kwechinhu.Naizvozvo, mukupisa kwakanyanya kwekuvaka kwezhizha, kuitira kuti uwane mhedzisiro yekuchengetedza mvura, zvinodikanwa kuwedzera emhando yepamusoro zvigadzirwa zveHPMC zvinoenderana neformula, zvikasadaro, pachave nekusakwana hydration, kudzikisa simba, kutsemuka, gollowing uye kudonha. zvinokonzerwa nekunyanya kuomesa.Kunowedzerawo kuoma kwekuvaka kwevashandi.Sezvo tembiricha inodzikira, huwandu hwekuwedzera hweHPMC hunogona kudzikiswa zvishoma nezvishoma, uye iyo yakafanana yekuchengetedza mvura inogona kuwanikwa.
Kuchengetwa kwemvura kwehydroxypropyl methylcellulose HPMC chigadzirwa pachayo kunowanzo kukanganiswa nezvinhu zvinotevera:
1. Cellulose ether HPMC homogeneity
Iyo yakafanana yakabatwa HPMC ine yunifomu yekugovera methoxy uye hydroxypropoxy mapoka uye yakakwirira kuchengetwa kwemvura.
2. Cellulose ether HPMC thermal gel tembiricha
Iyo yakakwirira tembiricha yekudziya gel, iyo yakakwirira yekuchengeta mvura;kana zvisina kudaro, iyo yakaderera mwero wekuchengetedza mvura.
3. Cellulose ether HPMC viscosity
Kana viscosity yeHPMC ichiwedzera, chiyero chekuchengetedza mvura chinowedzerawo;apo viscosity inosvika kune imwe nhanho, kuwedzera kwehuwandu hwekuchengetedza mvura kunowanzova munyoro.
4. Cellulose ether HPMC kuwedzera huwandu
Iyo yakakura iyo yakawedzerwa huwandu hweselulosi ether HPMC, iyo yakakwirira mwero wekuchengetedza mvura uye zvirinani mhedzisiro yekuchengeta mvura.Muchikamu che 0.25-0.6%, chiyero chekuchengetedza mvura chinowedzera nokukurumidza nekuwedzera kwekuwedzera kwekuwedzera;apo huwandu hwekuwedzera hunowedzera kuwedzera, kuwedzera kwemaitiro ekuchengetedza mvura kunononoka.
