Uburyo bworoshye bwo gupima hydroxypropyl selulose ether ibicuruzwa

1. Ethers ya selile (MC, HPMC, HEC)

MC, HPMC, na HEC bikoreshwa cyane mubwubatsi, gusiga irangi, minisiteri nibindi bicuruzwa, cyane cyane kubika amazi no gusiga. ni byiza.

Uburyo bwo kugenzura no kumenyekanisha:

Gupima garama 3 za MC cyangwa HPMC cyangwa HEC, ubishyire muri ml 300 y'amazi hanyuma ubireke kugeza bishonge burundu mubisubizo, shyira igisubizo cyamazi mumacupa yamazi meza, meza, yubusa, upfundike kandi uhambire ingofero, shyira muri Reba Impinduka zumuti wa kole mubidukikije -38 ° C. Niba igisubizo cyamazi gisobanutse kandi kiboneye, hamwe nubwiza bwinshi hamwe namazi meza, bivuze ko ibicuruzwa bifite ibitekerezo byiza byambere. Komeza kwitegereza amezi arenga 12, kandi ntagihinduka, byerekana ko ibicuruzwa bifite umutekano uhamye kandi bishobora gukoreshwa ufite ikizere; niba igisubizo cyamazi kibonetse gihindura buhoro buhoro ibara, kiba cyoroshye, gihinduka umuvurungano, gifite impumuro mbi, kugira imyanda, kwagura icupa, no kugabanya umubiri w icupa Guhindura byerekana ko ibicuruzwa bitameze neza. Niba ikoreshwa mugukora ibicuruzwa, bizaganisha ku bwiza bwibicuruzwa bitajegajega.

2. CMCI, CMCS

Ubukonje bwa CMCI na CMCS buri hagati ya 4 na 8000, kandi bukoreshwa cyane cyane mukuringaniza urukuta no guhomesha ibikoresho nkibisanzwe byimbere byimbere hamwe na plaster plaque yo kubika amazi no kuyasiga.

Uburyo bwo kugenzura no kumenyekanisha:

Gupima garama 3 za CMCI cyangwa CMCS, ubishyire muri ml 300 y'amazi hanyuma ubireke kugeza bishongeje burundu mubisubizo, shyira igisubizo cyamazi mumacupa yamazi meza, asobanutse, yubusa, upfundike kandi uhambire ingofero, hanyuma ubishyire muri Reba ihinduka ryumuti wamazi wacyo mubidukikije bya ℃, niba igisubizo cyamazi kibonerana, kibyimbye, kandi gitemba amazi, bivuze ko ibicuruzwa byumva ari byiza mugitangiriro, niba igisubizo cyamazi ari akajagari kandi gifite imyanda, bivuze ko ibicuruzwa birimo ifu yubutare, nibicuruzwa birasambana. . Komeza kwitegereza amezi arenga 6, kandi birashobora kuguma bidahindutse, byerekana ko ibicuruzwa bifite umutekano uhamye kandi bishobora gukoreshwa ufite ikizere; niba bidashobora kubungabungwa, usanga ibara rizahinduka buhoro buhoro, igisubizo kizagenda cyoroha, gihinduke ibicu, hazabaho imyanda, impumuro ya rancid, kandi icupa rizabyimba, byerekana ko ibicuruzwa bitajegajega, nibikoreshwa muri ibicuruzwa, bizatera ibibazo byubuziranenge bwibicuruzwa
