Liaparo le enke
Hydroxypropyl Cellulose e sebediswa e le sethibela-matheba le sethibela-matheba dikoahelong tse thehilweng metsing le dienkeng tsa ho hatisa ho thibela ho senyeha ha mmala le ho ntlafatsa thepa ya ho leka-lekanya ya dikoahelo (ho qoba matshwao a borashe).
Indasteri ea thepa ea kaho
Hydroxypropyl Cellulose e sebediswa ka hara seretse sa samente le phofo ya putty e le moemedi ya bolokang metsi (ho fokotsa mouwane o feteletseng wa metsi le ho thibela ho petsoha) le setenya (ho ntlafatsa ho phalla ha moaho).
Lisebelisoa tsa elektroniki
HPC e hloekileng haholo e sebelisoa e le resin e etsang filimi bakeng sa ho hanyetsa photoresist ts'ebetsong ea tlhahiso ea li-chip tsa semiconductor (lintho tse litšila li lokela ho laoloa ka thata).
1. Litlhaloso tse ngata tsa viscosity lia fumaneha. HPCS tse robeli tse fapaneng li tsamaisana le viscosity tse fapaneng ho latela tšimo ea meriana ea moreki. Phello ea ts'ebeliso e betere.
2. Dikahare tsa metsoako ya arsenic di tlase. Dikahare tsa arsenic tse mmarakeng di ka tlase ho 200 PPM, mme re ka di laola ho ba ka tlase ho 2PPM. Ho e eketsa dithethefatsing ha ho kotsi haholo ebile ho sebetsa hantle.
3. Re ka iketsetsa HPC e nang le viscosity e phahameng. Tlhaloso ea viscosity e phahameng e ka sebelisoa e le thepa bakeng sa litokisetso tsa ho lokolloa ka nako e telele le ho lokolloa ka taolo. Ka ho fetola viscosity, sekhahla sa ho lokolloa ha moriana se ka laoloa ka nepo, ka hona ho eketsa katleho ea tlhahiso ea sehlahisoa se felileng.
Metswako ya selulose ya Hydroxypropyl ke selulose ya tlhaho e fetotsweng, e entsweng ka selulose ya tlhaho ka phetoho ya dikhemikhale mme ha e na dikarolo tse rarahaneng tsa dikarolo tse ngata. Sesepa sa selulose sa Hydroxypropyl se tsebahala matjhabeng. Haeba o batla ho reka selulose ya hydroxypropyl, w e tla o fa theko e ntle. 25kg/drum.
