Kev Siv
Cov hmoov dawb los yog me ntsis daj los yog greyish los yog hmoov fibrous. Tsis muaj ntxhiab thiab tsis qab, yooj yim hlawv, nrog thermoplasticity. Nws swells hauv dej los ua ib qho pob tshab rau mis nyuj dawb viscous colloidal kua. Yaj hauv ethanol, insoluble hauv ether. Insoluble hauv dej thaum qhov kub siab tshaj 38 ℃.
Cov tshuaj emulsifiers, cov tshuaj pleev xim, cov tshuaj colloids tiv thaiv, cov tshuaj stabilizers, cov tshuaj suspending, thiab cov tshuaj thickeners. Hauv Nyiv Pooj, 70% ntawm cov no yog siv rau hauv kev lag luam tshuaj, ua cov ntawv khi ntsiav tshuaj, cov tshuaj pleev zaj duab xis, thiab lwm yam kev siv.
Nws yog siv los ua tus neeg sawv cev thiab tus neeg sawv cev tsim zaj duab xis hauv kev lag luam tshuaj, thiab ua tus neeg sawv cev tsim zaj duab xis, tus neeg faib tawm, tus neeg ruaj khov, tus neeg ua kom tuab, thiab lwm yam hauv kev lag luam tshuaj pleev ib ce, txheej, thiab kua mem.
- Siv ua cov nplaum: Hauv kev lag luam tshuaj, cov khoom no feem ntau yog siv ua cov nplaum, xws li cov nplaum rau cov ntsiav tshuaj, cov granules, thiab cov granules zoo, feem ntau suav txog 1-5% ntawm qhov hnyav ntawm cov tshuaj. Hom RT-L lossis RT-J raug xaiv.
- Siv ua cov khoom siv txheej zaj duab xis rau cov ntsiav tshuaj. HPC muaj cov khoom zoo heev rau kev tsim zaj duab xis, thiab cov zaj duab xis uas tshwm sim yog tawv thiab ywj, uas tuaj yeem sib piv rau cov yas yas. Los ntawm kev sib xyaw nrog lwm cov neeg sawv cev tiv taus kub Chemicalbook, kev ua tau zoo ntawm zaj duab xis tuaj yeem txhim kho ntxiv. Feem ntau, hom RT-L raug xaiv.
- Siv ua cov khoom ua kom tuab rau cov tshuaj elixirs, cov khoom ntxiv rau cov tshuaj pleev, thiab cov khoom ruaj khov rau cov tshuaj emulsions. Feem ntau, hom RT-M raug xaiv.
- Nws siv tau ua cov khoom siv matrix los npaj cov ntsiav tshuaj matrix sustained-release, sustained-release pellets, thiab cov ntsiav tshuaj ob txheej sustained-release. Feem ntau, hom RT-M raug xaiv.
5. Siv ua tus neeg sawv cev gelling hauv cov xwm txheej ethanol thiab ua lub hauv paus tshuaj pleev
Ntim thiab Xa Khoom
20kg / thawv raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
