UbuHydroxyPropyl Carboxymethyl selileIsoko ryo kugurisha cyane nibindi byinshi, igiciro ntabwo kiringaniye, uburyo bwo gukuraho vuba ubwiza bwa hydroxypropyl methyl Methyl Methyl Yabaye ikibazo gikomeye! Nigute rero gucira urubanza ubwiza bwa hydroxyproppopyl methylcellse? Ikintu cya mbere cyo kureba ni cyera wa hydroxyPropyl selile; Nubwo cyera zidashobora gusobanuka niba HPMC ibereye gusaba, ariko mugikorwa cyo gutunganya, harimo kandi abakora babi bazongeramo umukozi wambayeho, bazangiza ireme ryayo. Ariko muri rusange, ubwinshi bwa selile nziza nziza ni igimweru cyiza.
Icya kabiri, kugirango urebe ibyiza bya HydroxyPropyl Methyl Cellulose: HydroxyPropyl Carboxymethyl Ingano ya selile ya selile HPMC kuri mesh 60-80, general methyl solekiri, gutatanya neza.
Igisubizo cya selile ether neza:Hpmcshyira mumazi kugirango utange igisubizo cya colloid, reba hejuru imyanzuro, iriba ryiyemeje, ridashonga imiti iri hasi.
Iyo ibicuruzwa bishyuha, ni gelanine cyangwa ihujwe kandi byandikwa. Ni hydrophobic no gushonga amazi. Beto nimiti yingenzi no kwangiza ibikoresho fatizo bya powder irwanya amazi. Ihame rirwanya amazi ni ibi bikurikira: Muburyo bwo kongera amazi no kubyutsa ifu ya latex na sima ya latex ikomeza gusubira muburyo bwa emulsion yumwimerere, kandi ibice bya latex bitatanye bihari muri sima. Indwara ihuye n'amazi, imyitwarire ya hydration iratangira, kandi ca (OH) 2 igera ku byuzuza no guhugukira kristu, kandi icyarimwe, kalicumu na calcium ya silicate ya colloids yakozwe. Ibice bya latex bishyirwa kuri gel na sima idahwitse. Hamwe niterambere ryimyitwarire ya hydtion, ibicuruzwa byimiterere biriyongera, kandi ibice bya latex bigenda biteranyirizwa buhoro buhoro mu buryo bw'ibikoresho by'ibihangano nko muri sima, kandi bigize urwego rwo kwegeranya hejuru ya sima gel. Bitewe no kugabanya buhoro buhoro amazi yumye, apakiye cyane ibice bya latex muri gels no ku mutima akaba umwanya uhoraho, ugakora imvange ya sima, kandi ihuza sima Paste nizindi nkunga.
