Cellulose ether muri beto

Cellulose ether muri beto

Cellulose ether ni ubwoko bwa polymer-soluble polymer ikoreshwa mubikorwa bitandukanye, harimo na beto. Uru rupapuro rusubiramo ikoreshwa rya selile ya ether muri beto n'ingaruka zayo kumiterere ya beto. Uru rupapuro ruvuga ku bwoko bwa ethers ya selile ikoreshwa muri beto, ingaruka zayo kumitungo ifatika, nibyiza nibibi byo gukoresha ether ya selile muri beto. Uru rupapuro rusubiramo kandi ubushakashatsi buriho ku ikoreshwa rya selile ya selile muri beto kandi itanga ibyifuzo byubushakashatsi buzaza.

Intangiriro

Ethers ya selile ni ubwoko bwa polymer-soluble polymer yakoreshejwe mubikorwa bitandukanye, harimo na beto. Ether ya selile ikoreshwa mugutezimbere imikorere, imbaraga, nigihe kirekire cya beto. Zikoreshwa kandi mu kugabanya amazi yinjira, kunoza imiterere, no kugabanya kugabanuka. Ether ya selile isanzwe yongerwaho kuri beto muburyo bwo kuvanga amazi cyangwa ifu. Uru rupapuro rusubiramo ikoreshwa rya selile ya selile muri beto n'ingaruka zayo kumiterere ya beto.

Ubwoko bwa Cellulose Ethers

Ethers ya selile igabanijwemo ibyiciro bibiri byingenzi: hydroxyethylcellulose (HEC) na hydroxypropylcellulose (HPC). HEC ni ether ya ionic selulose ether ikoreshwa muri beto kugirango itezimbere imikorere, igabanye amazi, kandi igabanye kugabanuka. HPC ni anionic selulose ether ikoreshwa mugutezimbere no kugabanya amazi.

Ingaruka Kubintu Byiza

Ikoreshwa rya selile ya selile muri beto irashobora kugira ingaruka zikomeye kumiterere ya beto. Ether ya selile irashobora kunoza imikorere ya beto mukongera umuvuduko wa beto ivanze. Ibi birashobora kugabanya amazi akenewe kugirango ugere kubikorwa byifuzwa. Ether ya selile irashobora kandi kugabanya amazi no kugabanuka, bishobora kuzamura uburebure bwa beto. Byongeye kandi, selile ya selile irashobora kunoza guhuza hagati ya beto nibindi bikoresho, nkibyuma cyangwa ibiti.

Ibyiza n'ibibi

Gukoresha selile ya selile muri beto ifite ibyiza byinshi. Ether ya selile irashobora kunoza imikorere ya beto, kugabanya amazi no kugabanuka, no kunoza neza. Mubyongeyeho, ether ya selile irasa naho ihendutse kandi yoroshye gukoresha. Ariko, hari ibibi byo gukoresha selile ya ether muri beto. Ethers ya selile irashobora kugabanya imbaraga za beto, kandi irashobora no kugabanya umwuka wumwuka wa beto, ushobora kugabanya uburebure bwa beto.

Ubushakashatsi bwa none

Habayeho umubare munini wubushakashatsi bwakozwe ku ikoreshwa rya selile ya selile muri beto. Ubushakashatsi bwerekanye ko ethers ya selile ishobora kunoza imikorere no kugabanya amazi no kugabanuka kwa beto. Byongeye kandi, ubushakashatsi bwerekanye ko selile ya selile ishobora kunoza guhuza beto nibindi bikoresho. Nubwo bimeze bityo ariko, haracyakenewe ubundi bushakashatsi kugirango twumve neza ingaruka za selile ya selile kumiterere ya beto.

Umwanzuro

Ethers ya selile ni ubwoko bwa polymer-soluble polymer ikoreshwa mubikorwa bitandukanye, harimo na beto. Ethers ya selile irashobora kunoza imikorere, imbaraga, nigihe kirekire cya beto. Zishobora kandi kugabanya amazi yinjira no kugabanuka, no kunoza neza. Habayeho ubushakashatsi butari buke bwakozwe ku ikoreshwa rya selile ya selile muri beto, ariko haracyakenewe ubundi bushakashatsi kugira ngo twumve neza ingaruka za ethers ya selile ku miterere ya beto.
