HPMC kana hydroxypropyl methylcellulose ikomboni inowanzoshandiswa mumaindasitiri akasiyana siyana anosanganisira mishonga, zvizorwa uye kuvaka.Heano mimwe mibvunzo inowanzo bvunzwa nezve HPMC:
Chii chinonzi hypromellose?
HPMC i polymer yakagadzirwa kubva ku cellulose, chinhu chakasikwa chinowanikwa mumiti.Inogadzirwa nemakemikari ekugadzirisa cellulose nemapoka emethyl uye hydroxypropyl kugadzira poda inonyungudika nemvura.
HPMC inoshandiswa nei?
HPMC ine zvakawanda zvinoshandiswa mumaindasitiri akasiyana.Muindasitiri yemishonga, inoshandiswa sebinder, thickener uye emulsifier yemapiritsi, capsules uye mafuta ekuzora.Muindasitiri yezvizorwa, inoshandiswa seyakakora, emulsifier uye stabilizer mumakirimu, lotions uye make-up.Muindasitiri yekuvaka, inoshandiswa sebhainda, thickener uye inochengetedza mvura musemende nedhaka.
MaHPMC akachengeteka here?
HPMC inowanzoonekwa yakachengeteka uye isina chepfu.Inoshandiswa zvakanyanya mumaindasitiri emishonga uye cosmetic uko kuchengetedzeka nekuchena kwakakosha zvakanyanya.Nekudaro, sekunge chero kemikari, zvakakosha kubata HPMC nekungwarira uye kutevedzera kuchengetedzwa kwakaringana.
Ko HPMC inogona kuparara here?
HPMC inoodza uye inogona kuputswa nemaitiro echisikigo nekufamba kwenguva.Nekudaro, mwero we biodegradation unoenderana nezvinhu zvakasiyana senge tembiricha, humidity uye kuvapo kwemicroorganisms.
Ko HPMC inogona kushandiswa muchikafu here?
HPMC haina kutenderwa kushandiswa mukudya mune dzimwe nyika, kusanganisira United States.Nekudaro, inotenderwa sekuwedzera kwechikafu mune dzimwe nyika dzakadai seJapan neChina.Inoshandiswa seyakakora uye inodzikamisa mune zvimwe zvekudya, senge ice cream uye zvakabikwa zvinhu.
HPMC inogadzirwa sei?
HPMC inogadzirwa nemakemikari ekugadzirisa cellulose, chinhu chakasikwa chinowanikwa mumiti.Cellulose inotanga kurapwa nealkaline solution kubvisa tsvina uye kuita kuti iwedzere kushanda.Inobva yaita nemusanganiswa wemethyl chloride uye propylene oxide kuumba HPMC.
Ndeapi magiredhi akasiyana eHPMC?
Kune akati wandei mamakisi eHPMC, imwe neimwe iine akasiyana zvivakwa uye zvivakwa.Magiredhi anobva pazvinhu zvakaita sehuremu hwemamorekuru, dhigirii rekutsiva, uye tembiricha yegelation.Akasiyana mamakisi eHPMC anoshandiswa mune akasiyana maapplication mumaindasitiri akasiyana.
Ko HPMC inogona kusanganiswa nemamwe makemikari?
HPMC inogona kusanganiswa nemamwe makemikari kugadzira akasiyana ehupfumi uye maitiro.Inowanzo kusanganiswa nemamwe mapolymers akadai se polyvinylpyrrolidone (PVP) uye polyethylene glycol (PEG) kuti iwedzere kusunga kwayo uye kukora zvinhu.
HPMC inochengetwa sei?
HPMC inofanira kuchengetwa munzvimbo inotonhorera, yakaoma kure nehunyoro uye zuva rakananga.Inofanira kuchengetwa mumudziyo usingapindi mhepo kudzivirira kusvibiswa.
Ndezvipi zvakanakira kushandisa HPMC?
Zvakanakira kushandisa HPMC zvinosanganisira mashandiro ayo, kunyungudika kwemvura, uye biodegradability.Iyo zvakare isiri-chepfu, yakagadzikana, uye inoenderana nemamwe akawanda makemikari.Nekuchinja dhigirii yekutsiva uye huremu hwemamorekuru, zvimiro zvayo zvinogona kuchinjika nyore, zvichiita kuti ive yakakodzera kune dzakasiyana siyana dzekushandisa.
