Ndiani mugadziri we hypromellose?

Kima Chemical inopa huwandu hwakawanda hwezvigadzirwa zve hypromellose kuti isangane nezvinodiwa zvekushandisa kwakasiyana. Zvigadzirwa zvekambani hypromellose zvinowanikwa mune akasiyana viscosity mamakisi uye madhigirii ekutsiva (DS), pamwe neakagadziridzwa mafomati kuti asangane nezvinodiwa nevatengi.

Kima Chemical's hypromellose zvigadzirwa zvinogadzirwa uchishandisa yepamusoro yekugadzira tekinoroji uye yakasimba yemhando yekudzora matanho kuti ive nechokwadi chakafanana uye kuita. Zvigadzirwa zvekambani zve hypromellose zvakare zvinoenderana neakasiyana siyana epasi rose, kusanganisira USP, EP, JP, uye FCC.

Hypromellose imhando yepolymer inoshandiswa mumhando dzakasiyana dzemaindasitiri. Kima Chemical inotungamira mugadziri we hypromellose, inopa huwandu hwakasiyana hwemagiredhi uye yakatarwa kusangana nezvinodiwa zveakasiyana maapplication. Kima Chemical's hypromellose zvigadzirwa zvinogadzirwa uchishandisa yepamusoro dhizaini tekinoroji uye yakasimba yemhando yekudzora matanho kuti ive nechokwadi chakafanana uye kuita. Nezvayo zvakanakisa zvimiro uye kuwanda kwekushandisa, hypromellose chinhu chakakosha muzvigadzirwa zvakawanda uye maindasitiri.

Hypromellose, inozivikanwawo se hydroxypropyl methylcellulose (HPMC), inonzi semi-synthetic polymer iyo inoshandiswa mumhando dzakasiyana dzemaindasitiri. Inogadzirwa nekemikari inogadzirisa cellulose, yakasikwa polymer inowanikwa muzvirimwa. Hypromellose inowanzo shandiswa seyakakora, emulsifier, uye inodzikamisa muindasitiri yezvekudya, uye seanosungira, firimu-kare, uye lubricant muindasitiri yemishonga. Kima Chemical inotungamira mugadziri we hypromellose, inopa huwandu hwakasiyana hwemagiredhi uye yakatarwa kusangana nezvinodiwa zveakasiyana maapplication.

Kemikari Kuumbwa kweHypromellose

Hypromellosei polymer inonyungudika mumvura inotorwa kubva muselulosi. Inogadzirwa nekuita cellulose nepropylene oxide uye methyl chloride. Iyo polima inoguma ine huremu hwemamolecular huremu hwe10,000 kusvika 1,000,000 Daltons, zvichienderana nedhigirii rekutsiviwa (DS) uye giredhi reviscosity.

Iyo kemikari chimiro chehypromellose ine cellulose musana ine hydroxypropyl uye methyl mapoka akabatanidzwa kune anhydroglucose units. Iyo dhigirii yekutsiva (DS) inoreva avhareji nhamba yehydroxypropyl uye methyl mapoka paanhydroglucose unit. Iyo DS inogona kubva pa0.1 kusvika 2.5, zvichienderana nezvinodiwa zveiyo hypromellose.

Zvimiro zveHypromellose

Hypromellose ihupfu huchena kusvika kune-chena husina hwema uye husina kunaka. Iyo inonyungudika mumvura uye yakawanda organic solvents, asi hainyunguke mune yakawanda nonpolar solvents. Hypromellose ine yakakwira viscosity pakudzika kwakadzika, izvo zvinoita kuti ive inoshanda thickener uye binder. Iyo inewo yakanakisa firimu-inogadzira zvinhu, izvo zvinoita kuti zvive zvakakosha mukugadzirwa kwejasi nemafirimu.

Zvimiro zvehypromellose zvinoenderana nedhigirii rekutsiva (DS) uye giredhi reviscosity. Yepamusoro DS mamakisi ane yakanyanya solubility yemvura uye yakadzika gelation tembiricha, nepo yakaderera DS mamakisi ane yakakwirira gelation tembiricha uye nani kupisa kugadzikana. Iyo viscosity giredhi inotarisa ukobvu hweiyo hypromellose mhinduro uye kugona kwayo kugadzira gels.

Kushandiswa kweHypromellose

Hypromellose inoshandiswa mune dzakasiyana siyana maindasitiri, kusanganisira chikafu, mishonga, zvizorwa, uye kuvaka. Muindasitiri yezvekudya, hypromellose inoshandiswa seyakakora, emulsifier, uye inodzikamisa mumhando dzakasiyana dzezvigadzirwa, zvinosanganisira ice cream, sosi, uye zvakabikwa zvinhu. Muindasitiri yemishonga, hypromellose inoshandiswa sebinder, film-former, uye lubricant mumapiritsi, capsules, uye mafuta ekuzora. Inoshandiswawo sechinhu chinoputira mukugadzirisa-kusunungurwa kwemaitiro.

Muindasitiri yezvizorwa, hypromellose inoshandiswa seyakakora, emulsifier, uye firimu-yaimbova mumafuta ekuzora, makirimu, uye makeup zvigadzirwa. Muindasitiri yekuvaka, hypromellose inoshandiswa seyakakora uye bhainda mune simende-based zvigadzirwa, senge madhaka uye grouts.
