Ubani umkhiqizi we-hypromellose?

I-Kima Chemical inikeza izinhlobonhlobo zemikhiqizo ye-hypromellose ukuhlangabezana nezidingo zezinhlelo zokusebenza ezihlukahlukene.Imikhiqizo yenkampani ye-hypromellose iyatholakala ngezigaba ezahlukene ze-viscosity kanye namadigri okushintsha (DS), kanye nokwakheka okwenziwe ngokwezifiso ukuhlangabezana nezidingo ezithile zamakhasimende.

Imikhiqizo ye-hypromellose ye-Kima Chemical ikhiqizwa kusetshenziswa ubuchwepheshe bokukhiqiza obusezingeni eliphezulu kanye nezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ikhwalithi nokusebenza okungaguquki.Imikhiqizo yenkampani ye-hypromellose nayo iyahambisana namazinga ahlukahlukene aphesheya, okuhlanganisa i-USP, EP, JP, ne-FCC.

I-Hypromellose iyi-polymer eguquguqukayo esetshenziswa ezinhlobonhlobo zezimboni.I-Kima Chemical ingumkhiqizi ohamba phambili we-hypromellose, enikeza izinhlobonhlobo zamabanga kanye nokucaciswa ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezihlukahlukene.Imikhiqizo ye-hypromellose ye-Kima Chemical ikhiqizwa kusetshenziswa ubuchwepheshe bokukhiqiza obusezingeni eliphezulu kanye nezinyathelo eziqinile zokulawula ikhwalithi ukuze kuqinisekiswe ikhwalithi nokusebenza okungaguquki.Ngezakhiwo zayo ezinhle kakhulu kanye nohlu olubanzi lwezinhlelo zokusebenza, i-hypromellose iyisithako esibalulekile emikhiqizweni nasezimbonini eziningi.

IHypromellose, eyaziwa nangokuthi i-hydroxypropyl methylcellulose (HPMC), i-semi-synthetic polymer esetshenziswa ezinhlobonhlobo zezimboni.Yenziwe nge-cellulose eshintsha amakhemikhali, i-polymer yemvelo etholakala ezitshalweni.I-Hypromellose ijwayele ukusetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer embonini yokudla, futhi njenge-binder, ifilimu-yangaphambili, kanye ne-lubricant embonini yezemithi.I-Kima Chemical ingumkhiqizi ohamba phambili we-hypromellose, enikeza izinhlobonhlobo zamabanga kanye nokucaciswa ukuze kuhlangatshezwane nezidingo zezinhlelo zokusebenza ezihlukahlukene.

Isakhiwo seKhemikhali seHypromellose

I-Hypromeloseiyi-polymer encibilika emanzini etholakala ku-cellulose.Yenziwa ngokuphendula i-cellulose nge-propylene oxide ne-methyl chloride.I-polymer ewumphumela inebanga lesisindo se-molecular of 10,000 kuya ku-1,000,000 Daltons, kuye ngezinga lokushintsha (DS) kanye nebanga le-viscosity.

Isakhiwo samakhemikhali se-hypromellose siqukethe umgogodla we-cellulose one-hydroxypropyl kanye namaqembu e-methyl axhunywe kumayunithi we-anhydroglucose.I-degree of substitution (DS) isho inombolo emaphakathi ye-hydroxypropyl namaqembu e-methyl ngeyunithi ngayinye ye-anhydroglucose.I-DS ingaba kusuka ku-0.1 kuye ku-2.5, kuye ngezici ezifunwayo ze-hypromellose.

Izici ze-Hypromellose

IHypromellose iyimpushana emhlophe kuya kokumhlophe engenaphunga futhi ayinambitheki.Iyancibilika emanzini nasezincibilikisini eziningi eziphilayo, kodwa ayincibiliki ezincibilikisini eziningi ezingapholi.I-Hypromellose ine-viscosity ephezulu ekugxilweni okuphansi, okuyenza ibe yi-thickener ne-binder ephumelelayo.Ibuye ibe nezakhiwo ezinhle kakhulu zokwenza ifilimu, okwenza kube usizo ekukhiqizeni ama-coatings namafilimu.

Izici ze-hypromellose zincike ezingeni lokushintshwa (DS) kanye nebanga le-viscosity.Amabanga aphezulu e-DS anokuncibilika okukhulu kwamanzi kanye nezinga lokushisa eliphansi le-gelation, kuyilapho amamaki e-DS aphansi enamazinga okushisa e-gelation aphezulu kanye nokuzinza okungcono kokushisa.Ibanga le-viscosity linquma ubukhulu besisombululo se-hypromellose kanye nekhono layo lokwenza ama-gel.

Ukusetshenziswa kwe-Hypromellose

IHypromellose isetshenziswa ezinhlobonhlobo zezimboni, ezihlanganisa ukudla, ezemithi, izimonyo nezokwakha.Embonini yokudla, i-hypromellose isetshenziswa njenge-thickener, emulsifier, kanye ne-stabilizer emikhiqizweni eyahlukene, okuhlanganisa u-ayisikhilimu, amasoso, nezinto ezibhakwayo.Embonini yezemithi, i-hypromellose isetshenziswa njenge-binder, ifilimu-yangaphambili, kanye ne-lubricant kumaphilisi, amaphilisi, namafutha okugcoba.Iphinde isetshenziswe njenge-ejenti yokuhlanganisa ekwakhiweni okulawulwayo okukhishwayo.

Embonini yezimonyo, i-hypromellose isetshenziswa njenge-thickener, emulsifier, kanye nefilimu-yangaphambili kuma-lotions, okhilimu, nemikhiqizo yezimonyo.Embonini yezokwakha, i-hypromellose isetshenziswa njenge-thickener ne-binder emikhiqizweni esekwe usimende, njengama-mortars nama-grouts.
