Amavuta yo kwisiga HEC

Urwego rwo kwisigaHEC 

Hydroxyethyl selulose, yitwa HEC, isura ya fibrous yera cyangwa yoroheje yumuhondo fibrous ikomeye cyangwa ifu ikomeye, idafite uburozi kandi itaryoshye, ni iyitwa selile ya ionic selile. Hydroxyethyl selulose irashobora gushonga byoroshye mumazi, amazi akonje kandi ashyushye arashobora gushonga, igisubizo cyamazi ntigifite imiterere ya gel, gifite gufatira neza, kurwanya ubushyuhe, kudashonga mumashanyarazi rusange. Hydroxyethyl selulose ningirakamaro yamazi ya elegitoronike ya selile ether ya kabiri nyuma ya carboxymethyl selulose na hydroxypropyl methyl selulose kumasoko yisi.

 

Urwego rwo kwisiga HEC Hydroxyethyl selulose hydroxyethyl selulose nigikorwa cyiza cya firime ikora, ifata, ikabyimbye, stabilisateur kandi ikwirakwiza muri shampoo, imisatsi, imisatsi, kutabogama, kwita kumisatsi no kwisiga. Ifu yo kumesa ni ubwoko bwumwanda re - gutuza; Imashini irimo hydroxyethyl selulose ifite uburyo bugaragara bwo kunoza neza no guhuza imyenda.

 

Amavuta yo kwisiga HEC Hydroxyethyl selulose uburyo bwo gutegura ni ugushira ibiti, ubwoya bwa pamba na sodium hydroxide, kugirango ubone umusaruro wa alkali selulose nkibikoresho fatizo, nyuma yo kumenagura keteti ya reaction, mubihe bya vacuum muri azote, hanyuma ugafatanya na epoxy ethane yibibabi byamazi byari, byongeyeho etanol, acide acike, glyoxal, isuku, kutabogama hamwe no guhuza ibisubizo byubusaza, Hanyuma, ibicuruzwa byarangiye bitegurwa no gukaraba, kubura amazi no gukama.

Amavuta yo kwisiga HEC Hydroxyethyl selulose hamwe no kubyimba, guhuza, emulioni, guhagarikwa, gukora firime, kubika amazi, kurwanya ruswa, gutuza nibindi biranga, birashobora gukoreshwa cyane mumazi yo gucukura amavuta yibintu byabyimbye, bikwirakwiza, amarangi hamwe na wino, stabilisateur, resin, umusaruro wa pulasitike ukwirakwiza, ibikoresho bipima imyenda, ibikoresho byubaka nka sima na gypsum binder, umubyimba, umukozi wo gufata amazi, umukozi uhagarika hamwe na surfactant kubicuruzwa bya chimique ya buri munsi, umukozi urekura kumurima wa farumasi, gutwikira firime kuri tablet, blokeri kubikoresho bya skeleton, bifata kandi bigahindura inganda za elegitoroniki, nibindi.

Ku isoko ry’Ubushinwa, ikoreshwa rya hydroxyethyl selulose ryibanda cyane cyane ku mwenda, imiti ya buri munsi, peteroli n’inganda, ndetse no mu zindi nzego. Byongeye kandi, umusaruro wa hydroxyethyl selulose mu Bushinwa ahanini ni ibicuruzwa byo mu rwego rwo hasi, kandi ikoreshwa ryacyo ryibanda cyane ku mwenda wo hasi ndetse n’ibicuruzwa bya buri munsi. Ku isoko ryo mu rwego rwo hejuru, umubare w’ibigo bireba mu Bushinwa ni muto, umusaruro ntuhagije, kandi kwishingikiriza hanze ni byinshi. Bitewe no kuvugurura impande zombi hamwe na politiki yo kurengera ibidukikije, inganda z’inganda za hydroxyethyl selulose zihora zihindura kandi zikazamurwa, kandi igipimo cy’isoko ry’isoko ryo mu rwego rwo hejuru kizakomeza gutera imbere mu bihe biri imbere.

HEC Hydroxyethyl selulose nigicuruzwa cyingenzi cya selulose ether kiza kumwanya wa gatatu mubikorwa byo kugurisha no kugurisha kwisi. Ni selile ya elegitoronike idafite ionic selile, ishobora gukoreshwa cyane muri peteroli, irangi, irangi ryo gucapa, imyenda, ibikoresho byubaka, imiti ya buri munsi, ubuvuzi, ibikoresho bya elegitoroniki nizindi nganda, hamwe niterambere ryisoko ryagutse. Bitewe nibisabwa, umusaruro wa hydroxyethyl selulose mubushinwa uriyongera. Hamwe no kuzamura imikoreshereze no gukaza umurego muri politiki yo kurengera ibidukikije, inganda ziratera imbere zigana ku rwego rwo hejuru. Ibigo bidashobora kugendana n'umuvuduko w'iterambere mugihe kizaza bizavaho buhoro buhoro.

Hydroxyethyl selulose mu kwisiga, ibicuruzwa byita ku ruhu ninshingano nyamukuru yo gutunganya umusatsi, umukozi ukora firime, emulizing stabilisateur, gufatira hamwe, ibintu bishobora guteza ingaruka ni 1, ugereranije n'umutekano, birashobora kwizezwa ko bizakoreshwa, kubagore batwite muri rusange nta ngaruka, hydroxyethyl selulose idafite acne.

Hydroxyethyl selulose ni polymerike ya polymer ikoreshwa muburyo bwo kwisiga nkibikoresho byuruhu, imashini ikora firime na antioxydeant.

 

Ibibazo bigomba kwitonderwa mugihe ukoreshakwisigaamanotaHEChydroxyethyl selulose:

1. Mbere na nyuma yo kongeramo urwego rwo kwisiga HEC hydroxyethyl selulose, kubyutsa bigomba gukomeza kugeza igisubizo kiboneye kandi gisobanutse neza.

2. Shungura urwego rwo kwisiga HEC hydroxyethyl selulose mumashanyarazi avanze buhoro. Ntukayongereho kubwinshi cyangwa muburyo butaziguye.

 

3. Ubushobozi bwo kwisiga bwo mu rwego rwo kwisiga HEC hydroxyethyl selulose biragaragara ko bifitanye isano nubushyuhe bwamazi nagaciro ka PH, bityo rero tugomba kubyitaho byumwihariko.

4. Ntukigere wongera ibintu bya alkaline muruvange mbere yuko ifu ya hydroxyethyl selulose ikonjeshwa mumazi. Kongera agaciro ka PH nyuma yo gushyuha bifasha gushonga.

5. Mugihe gishoboka, ongeramo mildew inhibitor hakiri kare.

6. Nyuma ya hydroxyethyl selulose nyuma yo kuvurwa ntabwo byoroshye gukora uduce cyangwa imirima, ntanubwo bizakora colloide idashobora gushonga nyuma yo kongeramo amazi.
