Uburyo bwo gusenya HPMC hifashishijwe methylcellulose hifashishijwe hydroxypropyl

Hydroxypropyl methylcellulose, izwi kandi nka HPMC, ni ether ya cellulose itari ionic ikomoka ku ipamba itunganyijwe, ibikoresho bya polymer karemano, binyuze mu buryo butandukanye bwa shimi. Ni ifu y'umweru cyangwa umuhondo muto ishobora gushonga mu mazi byoroshye. Reka tuvuge ku buryo bwo gushonga bwa hydroxypropyl methylcellulose.

1. Hydroxypropyl methylcellulose ikoreshwa cyane cyane nk'inyongeramusaruro ku ifu ya putty, mortier na kole. Iyongewe kuri sima, ishobora gukoreshwa nk'ikintu gifata amazi kandi kidatuma amazi asohoka neza kugira ngo yongere ubushobozi bwo kuyasukura; iyongewe kuri putty na kole, ishobora gukoreshwa nk'igikoresho cyo gufata amazi. Kugira ngo twongere ubushobozi bwo kuyakwirakwiza no kongera igihe cyo kuyakoresha, dufata Qingquan Cellulose nk'urugero kugira ngo dusobanure uburyo bwo kuyasesa bwa hydroxypropyl methylcellulose.

2. Hydroxypropyl methylcellulose isanzwe ibanza kuvangwa no gukwirakwizwa n'amazi ashyushye, hanyuma yongerwamo n'amazi akonje, igakururwa hanyuma igakonjeshwa kugira ngo ishonge;

By’umwihariko: fata 1/5-1/3 cy’amazi ashyushye akenewe, uvange kugeza igihe umuti wongeyeho ubyimbye burundu, hanyuma ushyiremo igice gisigaye cy’amazi ashyushye, ashobora kuba amazi akonje cyangwa ndetse n’amazi y’urubura, hanyuma uvange ku bushyuhe bukwiye (10°C) kugeza ushongesheje burundu.

3. Uburyo bwo kunywesha ibinyabutabire by’umwimerere:

Suka hydroxypropyl methylcellulose mu cyuma cy’ingufu cyangwa ugishyiremo organic solvent, hanyuma wongeremo cyangwa ushyiremo amazi akonje kugira ngo ubishonge neza. Organic solvent ishobora kuba ethanol, ethylene glycol, nibindi.

4. Iyo habayeho gukururana cyangwa gupfunyika mu gihe cyo gushonga, ni ukubera ko gukurura bidahagije cyangwa kongerwamo icyitegererezo gisanzwe mu mazi akonje. Kuri iyi ngingo, kangura vuba.

5. Iyo uduheri twavutse mu gihe cyo gushonga, dushobora gusigara amasaha 2-12 (igihe runaka giterwa n'uburyo umuti umeze) cyangwa tukavanwaho hakoreshejwe isuku, imashini itera igitutu, nibindi, cyangwa twongeramo ingano ikwiye y'umuti ukuraho ifu.

Amabwiriza yo Kwirinda

Hydroxypropyl methylcellulose igabanyijemo ubwoko bushonga buhoro buhoro n'ubushonga ako kanya. Hydroxypropyl methylcellulose ishongeshwa ako kanya mu mazi akonje.
