HydroxyPropyl methylcellose (HPMC) chinhu chakakosha nehuremu hwakawanda hwekushandisa muindasitiri yemishonga pamwe nedzimwe maindasitiri akadai sekudya, cosmetics uye kuvaka. Kudiwa kweHPMC kwave kuri kuramba kuchikoshesa pamakore nekuda kwezvinhu zvaro zvakasarudzika zvakadai sekuremerwa, kusunga, kugadzirwa kwemvura uye nekuchengetwa kwemvura. Munyaya ino, isu tichakurukurirana neAlkaline kusiya nzira yekugadzira yehydroxyprupylmylcellose (HPMC).
Iyo Alkali inosvika nzira yekugadzira yeHydroxyprusyl methylcellose (HPMC) iri maitiro umo mheremalose anoshevedza uye methyl chloride muhusiku hweAlkali. Maitiro acho anoitika pasi pekupisa, kumanikidzwa uye nguva inodzorwa mamiriro ekugadzira yakakwirira mhando HPMC zvigadzirwa.
Nhanho yekutanga mukugadzira HPMC uchishandisa iyo alkaline kusiya nzira yekugadzira iyo yekugadzirira cellulose chigadzirwa. Cellulose inotanga kunatswa nekubvisa chero kusvibiswa uye kwakazoshandurwa kuita Alkali Cellalose nekurapwa neAlkali sodium hydroxide. Iyi nhanho ndeyekutsoropodza nekuti inowedzera kuitiswa kwemheremellive ine reagens inoshandiswa mumatanho anotevera.
Alkali cellulose inobatwa nemusanganiswa weProfylene oxide uye methyl chloride pasi pekudzora tembiricha nekumanikidzwa. Kuita kwacho pakati peAlkali cellalose uye iyo Reagent inoguma nekuumbwa kwechinhu chigadzirwa, iyo iri musanganiswa we hydroxypropropropropyl methylcellose uye zvimwe zvigadzirwa.
Musanganiswa wacho washambwa, usina kurapwa uye wakasviba kuti ubvise zvakasviba senge zvisina kufanira reagents uye ne-zvigadzirwa. Mhinduro yekukonzeresa yangobva yasangana nekuvapurwa kuti uwane yakanyanya kuchena hpmc chigadzirwa.
Iyo Alkali inosvika nzira yekugadzira yeHydroxyprupyl methylcellose (HPMC) ine zvakawanda zvakanakira zvichienzaniswa nedzimwe nzira dzekugadzira dzakadai sekutsausa. Chimwe chezvakanakira ndezvekuti ndiyo yakanyanya kushamwaridzana. Kusiyana nemamwe maitiro, nzira yeAlkali yekushandisa haina kushandisa holengenated sols inokuvadza kune zvakatipoteredza uye hutano hwevanhu.
Imwe mukana wenzira iyi ndiko kugadzirwa kwezvigadzirwa zvakakwirira zveHPMC zvigadzirwa. Mamiriro ekugadzirisa ezvekuita anoona kuti chigadzirwa chekupedzisira ndechekuti unyatsoenderana uye wakakodzera kune dzakasiyana siyana dzekushandisa.
Iko kushandiswa kweHPMC muindasitiri yemishonga kunoshorwa kugadzirwa kwemahwendefa, makapu uye mamwe mafomu madhageji. HPMC inogona kushandiswa seyekusvina, kupaza, kuwiriranisa mumiririri, etc. Iko kushandiswa kweHPMC mune izvi zvinoshandiswa zvinovimbisa kuti chimiro cheDosge ndechenyama yakakwirira uye inosangana nezvinodiwa zvinodiwa.
HPMC inoshandiswawo seanoridza mhere, emulsififier uye stabilizer mune indasitiri yechikafu. Iko kushandiswa kweHPMC muzvigadzirwa zvekudya zvinovimbisa kudzidziswa kusingaperi, viscosity uye mhando.
Mune indasitiri yekuvaka, HPMC inoshandiswa seyakawana simende inowedzera kuvandudza basa rekushanda, kuchengetwa kwemvura uye kusungira zvinhu zve simenti. Iko kushandiswa kweHPMC kunoita kuti zvigadzirwa zvekuvaka ndezvemhando yepamusoro uye inosangana nezvinodiwa zvinodiwa.
Mukupfupikisa, iyo Alkali isingaregi nzira yekugadzira yeHydroxyprEpyl methylcellose (HPMC) iri maitiro ekugadzira zvigadzirwa zveHPMC uye anoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana senge mishonga, chikafu, uye kuvaka. Iko kushandiswa kweHPMC mune izvi zvinoshandiswa zvinovimbisa kuti chigadzirwa chiri chemhando yepamusoro uye inosangana nezvinodiwa zvinodiwa. Iyi nzira yekugadzira ndeyese nharaunda ine hushamwari uye inoburitsa yakakwirira-yakanyanya yeHPMC chigadzirwa.
