Mu irangi ryamabuye, hydroxypropyl methylcellulose irashobora gukoreshwa aho gukoresha hydroxyethyl selile?

Ibicuruzwa bya Vitamine byose bikomoka kumpamba isanzwe cyangwa ibiti byimbuto, bikozwe muri etherification. Ibicuruzwa bitandukanye bya selile ikoresha ibikoresho bitandukanye bya etherifying. Imiti ya etherifingi ikoreshwa muri hydroxyethyl selulose (HEC) ni okiside ya Ethylene, naho imiti ya etherifying ikoreshwa muri hydroxypropyl methylcellulose (HPMC) nubundi bwoko bwimiti ya etherifing. (chloromethane na okiside ya propylene).

Mu irangi ryukuri rya szone hamwe n irangi rya latex, hydroxyethyl selulose irashobora gukoreshwa nkibyimbye.

Irangi ryamabuye ryukuri ryoroshe kugusha kubera ubwinshi bwa rusange hamwe nuburyo bwihariye. Birakenewe kongeramo umubyimba kugirango wongere ubwiza bwayo kugirango uhuze ubwiza busabwa kugirango utere mugihe cyubwubatsi, kunoza ububiko bwacyo, no kugera ku mbaraga runaka.

Niba ushaka irangi ryamabuye kugirango ugere ku mbaraga nziza, kurwanya amazi meza no guhangana nikirere, guhitamo ibikoresho fatizo no gushushanya amata ni ngombwa cyane.

Mubihe bisanzwe, ubwinshi bwa emulioni ikoreshwa muburyo bwiza bwo gusiga irangi ryamabuye bizaba byinshi.

Kurugero, muri toni y irangi ryamabuye nyayo, hashobora kuba 300 kg ya emulion yera ya acrylic na 650kg yumucanga wamabuye asanzwe. Iyo ibintu bikomeye bigize emulsiyo ari 50%, ingano ya 300kg ya emulsiyo nyuma yo gukama ni litiro 150, naho ubunini bwa 650 kg bwumucanga ni litiro 228. Ni ukuvuga, PVC (ubunini bwa pigment) yibara ryukuri ryamabuye ni 60% muriki gihe, kubera ko ibice byumucanga wamabara ari binini kandi bidasanzwe, kandi muburyo bwo gukwirakwiza ingano nini, byumye irangi ryamabuye rishobora kuba muri CPVC (concentration ya mass mass). Ingano ya pigment yibanze) hafi. Kubyerekeranye no kubyimbye, niba uhisemo selile hamwe nubwiza bukwiye, irangi ryamabuye rishobora gukora firime yuzuye yuzuye kandi yuzuye kugirango ihuze ibintu bitatu byingenzi bisabwa irangi ryamabuye. Niba ibikubiye muri emulioni yamabuye nyayo ari bike, birasabwa gukoresha selile hamwe nubukonje bwinshi nkubunini (nka 100.000 viscosity), cyane cyane nyuma yigiciro cya selile yiyongereye, gishobora kugabanya umubare wa selile yakoreshejwe kandi ugakora ibuye ryukuri Imikorere y irangi nibyiza.

Bamwe mubakora ubukungu nyaburanga bakora amarangi bakoresha hydroxypropyl methylcellulose aho gukoresha hydroxyethyl selulose kubiciro nibindi bintu.

Ugereranije nubwoko bubiri bwa selile, hydroxyethyl selulose ifite amazi meza, ntizabura amazi kubera gelatine mubushyuhe bwinshi, kandi ifite imbaraga zo kurwanya indwara. Kubitekerezo byimikorere, birasabwa gukoresha hydroxyethyl selulose hamwe nubwiza bwa 100.000 nkibibyimbye kugirango irangi ryamabuye.
