Parizvino, mhando yeiyo hydroxypresspropropropyl methyelsellose inosiyana zvakanyanya, uye mutengo unosiyana kwazvo, zvichiita kuti zviome kuti vatengi vaite sarudzo yakanaka. Iyo yakagadziridzwa hpmc yekambani imwe chete yekune dzimwe nyika ndiyo mhedzisiro yemakore mazhinji ekutsvagisa. Kuwedzera kwezvinhu zvekutsvaga kunogona kuvandudza maitiro ekuvaka uye kugadzirisa zvinowanikwa. Ehe, zvinokanganisa zvimwe zvivakwa, asi zvinowanzotaura zvakanyatsoshanda; Icho chete chinangwa chekuwedzera zvimwe zvinoshandiswa kuderedza mari, zvichikonzera kuchengetwa kwakadzikira kwemvura zvakanyanya, kubatana uye zvimwe zvinhu zvechigadzirwa, zvichikonzera matambudziko mazhinji ekuvaka.
Pane kutevera misiyano pakati pePPMC yakachena uye yakadimburwa HPMC:
1. Yakachena HPMC ndeyekuona fluffy uye ine yakaderera bulk density, inotanga kubva 0.3-0G / ml; Hpmc HPMC ine zvishoma zvishoma uye inonzwa inorema, iyo iri pachena yakasiyana neyakagadzirwa neyakagadzirwa nechitarisiko.
2. Yakachena HPMC yemvura mhinduro yakajeka, yakakwirira yechiedza chinoputika, uye kudzokorora kwemvura ≥ 97%; Yakapomerwa HPMC Mvura mhinduro ndeye makore, uye iyo yemvura yekuchengetwa yakaoma kusvika 80%.
3. Yakachena HPMC haifanirwe kunhuhwirirai Amonia, mhizha nedoro; HpMC HPMC inowanzo kunhuhwirira marudzi ese ekunhuhwirira, kunyangwe isina kunaka, ichanzwa kurema.
4 HpMC HPMC inogona kucherechedzwa sedono solids kana makristasi pasi pe microscope kana girazi rekukudza.
Kukwirira kunoshamisa kwe200,000?
Nyanzvi dzakawanda dzepamba uye nyanzvi dzakaburitsa mapepa anotenda kuti HPMC kugadzirwa kwemidziyo yekuchengetedzeka kwemidziyo uye kuiswa-kudzvanywa, uye mabasa akaderera haagoni kugadzira zvigadzirwa newisikoka zvinopfuura 200,000. Muchirimo, hazvigoneke kugadzira zvigadzirwa newisikova zvevanopfuura 80,000. Vanotenda kuti zvinonzi zvinonzi 200,000 zvigadzirwa zvinofanirwa kunge zviri zvekunyepa zvigadzirwa.
Nharo dzemunyanzvi hadzisi dzisinganzwisisike. Maererano nemamiriro ekare epamba ekugadzira, mhedzisiro dziri pamusoro dzinogona kudhonzwa.
Kiyi yekuwedzera iyo viscosity yeHPMC ndeyekuiswa kwepamusoro kwekusimbisa kweanoshanda uye nekumusoro-kudzvanywa kuita pamwe nemhando yepamusoro-mhando zvinhu. Iyo yakakwira airchness inodzivirira kusvibiswa kwe cellenline neokisijeni, uye iyo yakakwira-yekumanikidza maitiro ekuita inosimudzira mugove weiyo erthification mumakanzuru uye inovimbisa kufanana kwechigadzirwa.
Iyo yekutanga index ya200000CPS hydroxypronyl methylcellose:
2% Aquous Solution Viscosity 20000000cps
Chigadzirwa Chaicho Kuchena kwe898%
Mukati Mukati 19-24%
Hydroxyprondyo yezvinyorwa: 4-12%

2. Kuwedzera kusimba kusimba uye kwakakosha mweya-kupinza maitiro, zvinobudirira inhibit shrinkage uye kupaza.

4.
5. Zvigadzirwa zvakakosha, uchivavarira kunzvimbo dzakakwirira dzekuvaka dzechirimo muzhizha, kuve nechokwadi che hydration inoshanda yeiyo slurry isina dutu.
Nekuda kweiyo Lax Market kutariswa, kukwikwidza muindasitiri yemotokari kuri kuwedzera kutyisa. Kuti vatevedzere kumusika, vamwe vatengesi vakasanganisa huwandu hwakawanda hwezvinhu zvakaderera-zvakarasikirwa kuburitsa zvakachipa celleulose ether. Pano, mupepeti anosungirwa kuyeuchidza vatengi kuti vasateemhere nemitengo yakaderera, kuti irege kunyengerwa, tungamira tsaona dzekunzi, uye pakupedzisira kurasikirwa kunopfuura zvinowanikwa.
Nzira dzakajairika dzezuva uye nzira dzekuzivikanwa:
.
Nzira yekuzivikanwa: Nekuda kwehunhu hweMigwagwa, rudzi urwu rwe cellulose ether mhinduro inowanzove nehuremu mushure mekuparadza, mhinduro yakafanana neye Jelly, so-inonzi inonamira asi isina kubatana.
(2) wedzera starch to cellulose ether. Starch kazhinji inoshambadza mumvura, uye mhinduro inowanzo kuve nerombo risina kujeka.
Nzira yekuzivikanwa: donhedza cellulose ether mhinduro neIodine, kana ruvara rwakashandurwa bhuruu, zvinogona kutariswa kuti starch yakawedzerwa.
(3) Wedzera Polyvinyl doro poda. Sezvo isu tese tinoziva, mutengo wemusika wePolyvinyl doro poda senge 2488 uye 1788 zvinowanzove zvakaderera ether, uye kusanganisa polyvinyl hupfu hunogona kuderedza mutengo we cellulose ether.
Nzira yekuzivikanwa: Rudzi urwu rwe cellulose ether inowanzo granular uye dense. Kukwirisa nekukurumidza nemvura, sarudza mhinduro ine tsvimbo yegirazi, kuchave nechimwe chinhu chiri pachena chega chekutonga.
Pfupiso: Nekuda kwechimiro chayo chakakosha uye mapoka, kuchengetwa kwemvura kwemasero e cellulose ether hakugone kutsiviwa nezvimwe zvinhu. Hazvina mhosva kuti nderipi yemhando yemhando yakasanganiswa mukati, chero bedzi ichivhenganiswa mumubatanidzwa mukuru, kuchengetwa kwemvura kwaro kuchadzikiswa. Iyo huwandu hweHPMC ine yakajairika viscosity ye10w mune yakajairika moter ndeye 0.15 ~ 0.2 ‰, uye iyo Mvura Yekutungamira Rwiyo> 88%. Kubuda ropa kwakanyanya. Naizvozvo, iyo yekuchengetwa kwemvura chiratidzo chakakosha kuyera mhando yeHPMC, ingave yakanaka kana yakaipa, chero bedzi ichiwedzerwa kune dhaka, zvichave pachena.
