Inganda za HPMC-ingaruka za viscosities zitandukanye za selile ya selile kuri poro ya putty

kumenyekanisha:

Ether ya selile ikoreshwa cyane mubikorwa byubwubatsi kubera gufata neza amazi, kubyimba no guhuza. Batezimbere imigendekere nibikorwa bya sima kandi bitezimbere imiterere yibicuruzwa byanyuma. Ibishishwa bikunze gukoreshwa mubikorwa byubwubatsi kugirango yuzuze ibice, umwobo nizindi nenge zidatunganijwe kurukuta no hejuru. Imikoreshereze ya selile ya selile mumashanyarazi irashobora kunoza imikorere, igashyiraho igihe nubuziranenge bwibicuruzwa. Iyi ngingo izaganira ku ngaruka za viscosities zitandukanye za selile ya selile kuri poro.

Ubwoko bwa selulose ethers:

Hariho ubwoko butandukanye bwa selile ya selile harimo methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), Ethylcellulose (EC) na carboxymethylcellulose (CMC). HPMC ni selile izwi cyane ya selile mubikorwa byubwubatsi kubera gufata neza amazi, kubyimba no gufatira hamwe. HPMC ije muburyo butandukanye, kuva hasi kugeza hejuru.

Ingaruka ya selile ya ether kuri poro ya putty:

Ifu yuzuye ikoreshwa mukuzuza ibice, umwobo nibindi bidatunganye murukuta no hejuru. Gukoresha selile ya selile muri porojeri irashobora kunoza imikorere no kugena igihe cyibicuruzwa. Ether ya selile irashobora kandi kunoza imikorere no gufatira ifu ya putty. Ibikurikira ningaruka za viscosities zitandukanye za selile ya ether kuri poro yuzuye:

1. Ubukonje buke HPMC:

Ubukonje buke HPMC irashobora guteza imbere amazi no gukora ifu ya putty. Itezimbere kandi igihe cyo kugena ibicuruzwa. HPMC ifite ubukonje buke ifite ubushyuhe buke bwa gelation, bushobora kubuza ifu ya putty gukomera vuba. Irashobora kandi kunoza guhuza no guhuza ibicuruzwa. Ubukonje buke HPMC ikwiranye nifu ya putty isaba gukora neza no gukora neza.

2. Ubucucike buciriritse HPMC:

Hagati ya viscosity HPMC irashobora kunoza imitekerereze ya thixotropique yifu ya putty. Irashobora kandi kunoza uburyo bwo gufata amazi no guhuza ibicuruzwa. Hagati ya viscosity HPMC irashobora kunoza imiterere yibicuruzwa, nkimbaraga nigihe kirekire. Irakwiriye ifu yuzuye isaba gufata neza amazi hamwe.

3. Ubukonje bukabije HPMC:

Ubukonje bwinshi HPMC irashobora kunoza imikorere no kurwanya anti-sag ya poro ya putty. Irashobora kandi kunoza uburyo bwo gufata amazi no guhuza ibicuruzwa. Ubukonje bukabije HPMC irashobora kunoza imiterere yibicuruzwa, nkimbaraga nigihe kirekire. Irakwiriye ifu yuzuye isaba kubyimba cyane no kurwanya anti-sag.

mu gusoza:

Ether ya selile ikoreshwa cyane mubikorwa byubwubatsi kubera gufata neza amazi, kubyimba no guhuza. HPMC yabaye selile izwi cyane muri selile yubwubatsi kubera ibyiza byayo. HPMC ije muburyo butandukanye, kuva hasi kugeza hejuru. Gukoresha ethers ya selile ifite viscosities zitandukanye birashobora kunoza imikorere, gushiraho igihe, imikorere ya thixotropique, kubika amazi, guhuza ibikorwa hamwe nubukanishi bwifu yifu. Imikoreshereze ya selile ya selile irashobora kuzamura ubwiza nigikorwa cyifu ya putty, bigatuma ikoreshwa muburyo butandukanye mubikorwa byubwubatsi.
