Cellulose HPMC, kana hydroxypropyl methylcellulose, inoshandiswa zvakanyanya muindasitiri yekupfeka. Icho chinhu chisina chepfu, chinoshanda zvikuru uye chinoshandiswa zvakasiyana-siyana. HPMC inotorwa kubva kune chirimwa fiber uye inonyungudika nyore mumvura. Iyo ine huwandu hwakasiyana hwekushandisa mukuvaka zvinhu, coating formulations, adhesives uye mamwe maindasitiri ane hukama.
Cellulose HPMC inouya mumhando mbiri: pakarepo uye isiri-pakarepo. Imwe neimwe ine yayo yakasarudzika zvivakwa uye yakakodzera kune chaiyo maapplication. Muchikamu chino, tichaongorora mutsauko uripo pakati pekukurumidza cellulose HPMC uye isiri-instant cellulose HPMC yekupfeka.
Instant Cellulose HPMC
Instant Cellulose HPMC imhando yeHPMC inonyungudika mumvura inotonhora. Iine nguva yekukurumidza kupera, zvinoreva kuti inogona kuparadzirwa mumvura mukati memasekondi. Instant HPMC inowanzo shandiswa mumachira anoda kukurumidza kukora, senge kumiswa, emulsions uye yakakwirira viscosity application.
Imwe yemabhenefiti makuru ekukurumidza cellulose HPMC ndeye yakanakisa dispersibility. Inonyungudika mumvura isina mapundu kana mapundu. Hunhu uhwu hunoita kuti ive yakanakira kushandiswa mune yakakwira solids maumbirwo sezvo ichigonesa kuenderana viscosity mubatch yese.
Instant cellulose HPMC inoshandawo zvakanyanya, ichipa yakanakisa thickening zvivakwa panzvimbo yakaderera. Iyo haina kukanganisa ruvara kana kupenya kwepende, zvichiita kuti ive yakakodzera kune akawanda magadzirirwo. Mukuwedzera, pakarepo HPMC inopesana nemakemikari, acids, uye alkalis, zvinoreva kuti ine kugadzikana kwakanaka kwemakemikari.
Non-instant cellulose HPMC
Kune rimwe divi, isiri-instant cellulose HPMC haina kunyungudika mumvura inotonhora uye inoda kupisa kuti iparare. Zvinotora nguva yakareba kunyungudika kupfuura instant cellulose HPMC uye inoda tembiricha yepamusoro kuti ipararire zvizere. Kwete-pakarepo HPMCs anowanzo shandiswa mumachira uko kunononoka uye zvishoma nezvishoma ukobvu kunodiwa.
Imwe yemabhenefiti makuru eiyo isiri-instant cellulose HPMC kugona kwayo kupa zvishoma nezvishoma kukora mhedzisiro nekufamba kwenguva. Izvo hazvikonzeri kushanduka kamwe kamwe mu viscosity iyo inogona kukanganisa huwandu hwese hwepende. Isiri-pakarepo HPMC ine yakanakisa rheological zvimiro uye yakanakira kushandiswa mumachira uko kunodiwa dhigirii rekutonga pamusoro pekuyerera uye kuenzana kwechigadzirwa.
Non-instant cellulose HPMC inewo yakanakisa firimu-inogadzira zvimiro, zvinoreva kuti inobatsira kuvandudza kusimba kwemajasi. Inogona kumirisana nemamiriro ekunze, UV radiation uye zvimwe zvinhu zvakatipoteredza, kuve nechokwadi kuti iyo coating inoramba yakasimba nekufamba kwenguva. Uye zvakare, isiri-yekare HPMC ine yakanaka kunamatira kwepamusoro, iyo inodzivirira kupfekedza kubva pakupepeta kana kuputika.
Yese instant uye isiri-yekare cellulose HPMC ine yakasarudzika zvivakwa uye mabhenefiti anoita kuti ive yakakodzera kune chaiwo maapplication muindasitiri yekukoira. Instant cellulosic HPMC yakanakira machira anoda kukurumidza kukora, nepo isiri-pakarepo HPMC yakanakira maapplication anoda kunononoka uye zvishoma nezvishoma ukobvu.
Zvisinei nerudzi rweselulosi HPMC yakashandiswa, zvakanakira izvi zvakasiyana-siyana hazvirambike. Iyo inowedzera kukosha kune machira nekuvandudza thickening, leveling, adhesion uye durability. Uyezve, haina muchetura uye ine hushamwari kwezvakatipoteredza, zvichiita kuti ive sarudzo yakanakisa yemagadzirirwo ane chinangwa chekudzikisira kukanganisa kwavo kwezvakatipoteredza.
Cellulose HPMC chinhu chinoshanda zvakanyanya uye chinogoneka chinogona kuunza zvakakosha mabhenefiti. Kushandiswa kwaro kunokosha pakuvandudza kunaka kwepende, iyo inopedzisira inokanganisa kugutsikana kwese kwemushandisi wekupedzisira.
