Hydroxypropyl methylcellulose HPMC uburyo bwo gusesa

Hydroxypropyl methylcellulose, izwi kandi ku izina rya HPMC, ni ether ya selulose ether ikomoka mu ipamba itunganijwe, ibikoresho bya polymer bisanzwe, binyuze mu ruhererekane rw'imiti.Nifu yera cyangwa yumuhondo yoroheje byoroshye gushonga mumazi.Reka tuvuge uburyo bwo gusesa hydroxypropyl methylcellulose.

1. Hydroxypropyl methylcellulose ikoreshwa cyane cyane nk'inyongeramusaruro ya poro, pome na kole.Wongeyeho kuri sima ya sima, irashobora gukoreshwa nkibikoresho bigumana amazi na retardant kugirango byongere ubushobozi;wongeyeho ifu ya putty na kole, irashobora gukoreshwa nka binder.Kugirango tunoze ikwirakwizwa no kongera igihe cyo gukora, dufata Qingquan Cellulose nkurugero rwo gusobanura uburyo bwo gusesa hydroxypropyl methylcellulose.

2. Hydroxypropyl methylcellulose isanzwe ibanza gukangurwa no gukwirakwizwa n'amazi ashyushye, hanyuma ikongerwamo amazi akonje, ikabyutsa ikonjeshwa kugirango ishonga;

By'umwihariko: fata 1 / 5-1 / 3 by'amazi asabwa asabwa, koga kugeza igihe ibicuruzwa byongewe byabyimbye burundu, hanyuma ushyiremo igice gisigaye cy'amazi ashyushye, gishobora kuba amazi akonje cyangwa n'amazi ya barafu, hanyuma ukabyutsa ubushyuhe bukwiye (10 ° C) kugeza bishonge burundu.

3. Uburyo bwo guhanagura ibishishwa:

Kwirakwiza hydroxypropyl methylcellulose mumashanyarazi kama cyangwa ukayungurura hamwe na solge kama, hanyuma ukongeramo cyangwa ukongeramo amazi akonje kugirango uyashonge neza.Umuti ukungahaye urashobora kuba Ethanol, Ethylene glycol, nibindi.

4. Niba agglomeration cyangwa gupfunyika bibaye mugihe cyo guseswa, ni ukubera ko gukurura bidahagije cyangwa icyitegererezo gisanzwe cyongewe kumazi akonje.Kuri iyi ngingo, kangura vuba.

5. Niba ibibyimba byabyaye mugihe cyo guseswa, birashobora gusigara mumasaha 2-12 (igihe cyihariye giterwa no guhuza igisubizo) cyangwa gukurwaho na vacuuming, kotsa igitutu, nibindi, cyangwa ukongeramo umubare ukwiye wumukozi wo gusebanya.

Kwirinda

Hydroxypropyl methylcellulose igabanijwemo buhoro buhoro kandi buhoro buhoro.Hydroxypropyl methylcellulose ako kanya irashobora gushonga mumazi akonje.
