Gusaba no gutanga dosiye ya HPMC mu kwishyira hejuru

Kwirinda kwigaragaza ni ingenzi zimenyerewe zikoreshwa muguhuza no guhuza inganda mu nganda zitandukanye. Umutungo wacyo wihariye utuma ari byiza kubisabwa bisaba ubuso bworoshye, burya, nko gushushanya no gushushanya no kwinjiza urukuta.

Kimwe mu bintu byingenzi bigize uburyo bwo kwiheba ni hydroxypropyl methylcellse (HPMC). HPMC ni ukomoka kuri selile kandi ikoreshwa cyane mubice, ibikoresho byubaka, ibihuma hamwe nibindi bice.

Uruhare nyamukuru rwa HPMC mu kwishyira hejuru ni ukugenzura vicosity no guhuzagurika. Ibiranga viscoelastique ya HPMC yemerera ibifatika kugirango bitemba neza kandi bigoramye, buremeza hejuru kandi iri hejuru nyuma yo gusaba.

HPMC itezimbere ibintu byo guhunika kwishyira hejuru, bigatuma igisubizo cyiza cyo guhuza ibice bitandukanye. Ibi biterwa nubushobozi bwihariye bwa HPMC bwo gukora ubumwe bukomeye hamwe nubuso butandukanye, harimo na beto, ibiti nicyuma.

Umubare wa HPMC ukoreshwa mu myifatire yo kwigaragaza biterwa nibintu bitandukanye, harimo ubwoko bwa substrate, guhuza ibikorwa byifuzwa hamwe nuburyo bwihariye bwo gusaba. Muri rusange, urupapuro rwasabwe na HPMC ni 0.1% kuri 0.5% kuburemere bwa forelation.

Mugihe wongeyeho HPMC kugirango wirinde kwigaragaza, bigomba kuvanga neza nibindi bintu bifatika. Ibi bireba no gukwirakwiza HPMC, bikavamo gufata neza kandi rimwe.

HPMC igira uruhare runini mugushiraho ibyopite. Ibicuruzwa byayo bya visoelastique bigira igisubizo cyiza cyo kugera kubintu byoroshye, bifite uburinganire mugihe nabyo bizana imitungo yo guhuza imigabane. Igipimo cyukuri no gusaba HPMC ni ngombwa kugirango ubone imikorere yifuzwa yo kwishyira hejuru.
