Veccosity ni iki hec?

Ultra-Hejuru Helcoxity HydroxyEthyll Cellulose (HEC) ni ikigo cya polymer cyoroshye cyamazi cyakozwe muguhinduranya selile. Kubera ubukuru bwayo budasanzwe no gushikama, HEC ikoreshwa cyane mubice byinshi nka kwisiga, imiti, kubaka, no gukuramo peteroli.

(1), imiterere ya hec hamwe nuburyo bwo gutegura

1.1 Imiterere
HEC ni ether bakomoka mu kuvura imiti ya selile kamere. Igice cyacyo cyibanze ni β-D-glucose, ihujwe na β-1,4 glycosic. Itsinda rya Hydroxyl (-Oh) muri selile ryasimbuwe na Eorylene Oxide (eo) cyangwa izindi shami rirenga, bityo imenyekanisha itsinda rya Ethoxy (-ch2ch2oh rishyiraho Ethoxythyl. Ultra-Hejuru Hec ifite uburemere bwo hejuru bwa molekile, mubisanzwe hagati ya miriyoni nimiryango icumi, bituma bimurikana ubuswa cyane mumazi.

1.2 Uburyo bwo gutegura
Gutegura HEC bigabanyijemo ahanini mu ntambwe ebyiri: Pretaye yo kwitegura kwa selile na gato.

Kwitegura selile: selile karemano (nka pamba, igiti, nibindi) yavuwe hamwe na alkali kugirango irambuye kandi igatandukanya iminyururu ya selile yo guhagarika.

Ibyifuzo byanyuma: Muburyo bwa alkaline, ikarigo yateguwe yakozwe hamwe na etylene okiside cyangwa izindi mbaraga zinyamiye kugirango utangire amatsinda ya hydroxyyerytyl. Inzira yimyitwarire yibasiwe nibintu nkubushyuhe, igihe, no gukurikiranya abakozi kwibandaho, na Hec hamwe na dogere zitandukanye zo gusimbuza (DS) no gusimbuza uburinganire (MS) amaherezo babonetse. Ultra-Hejuru viscosity Hec muri rusange isaba uburemere bukomeye bwa molekile hamwe nurwego rukwiye rwo gusimburwa kugirango habeho ibiranga viscosity mumazi.

(2) Ibiranga Hec

2.1 Kukemerera
HEC irashonga haba mu mazi akonje n'amazi ashyushye, akora igisubizo gisobanutse cyangwa gisobanutse neza. Igipimo cy'imisevu kigira ingaruka ku bintu nk'uburemere bwa molecular, urwego rwo gusimbuza, n'ubushyuhe bwo gukemura. Ultra-Hejuru Hec Hec ifite ibibazo bike cyane mumazi kandi bisaba gukurura igihe kirekire kugirango ushishoze rwose.

2.2 viccosity
Viscosity ya ultra-alcosity victcosity hec nibiranga cyane. Ubukuru bwayo ubusanzwe buturuka ku bihumbi by'ibihumbi n'ibihumbi by'indipa · (bitewe no kwibanda, ubushyuhe, n'amafaranga yogosha. Uruzinduko rwa HEC ntabwo ruterwa nuburemere bwa molekingo, ahubwo bifitanye isano rya bugufi nurwego rwo gusimburwa muburyo bwa molekelar.

2.3 Guhagarara
HEC ifite umutekano mwiza muri acide, alkalis hamwe nibibazo byamagari kandi ntabwo byangiritse byoroshye. Mubyongeyeho, ibisubizo bya hec bifite ubukorikori bwiza kandi birashobora kugumana ubukuru bwabo nibindi bindi byumubiri na shimi mugihe kirekire.

2.4 Guhuza
HEC ihujwe n'imiti nini, harimo ibyiciro, umunyu n'andi mazi make. Guhuza neza bituma bituma bikomeza imikorere ihamye muri sisitemu yo gutenguha.

(3) Gusaba Hec

3.1 Amavuta yo kwisiga hamwe nibicuruzwa byita kugiti cyawe
Muri kwisiga, HEC ikoreshwa cyane nkumubyimba, stabilizer na umukozi wa firime. Ultra-Hejuru Hec irashobora gutanga gukoraho neza no gutuza cyane kandi bikunze gukoreshwa mubicuruzwa nko kwisiga, shampoos, na kondera.

3.2 Inganda za farumasi
Nk'igituba cya farumasi, HEC ikoreshwa kenshi mugutegura ibinini byarakaye, gels nizindi myiteguro ya farumasi. Umutungo wacyo mwinshi urashobora kugenzura igipimo cyo kurekura ibiyobyabwenge no kunoza ibinyabuzima byabiyobyabwenge.

3.3 Ibikoresho byo kubaka
Mu nganda zubwubatsi, hec ikoreshwa nkumuntu wijimye hamwe numukozi ugumana amazi kugirango yameneme nibikoresho bishingiye ku banyarwanda. Ukubahwa kwayo kwinshi no kubangamira amazi meza bifasha kuzamura imikorere yubwubatsi no kwirinda ibikoresho byuma no kugandukira.

3.4 Gukuramo amavuta
Mu nganda za peteroli, Hec ikoreshwa mumazi yo gucukura no guswera nkawe mubyimbye kandi akurura. Ultra-Hejuru Hec irashobora kunoza ubushobozi bwo guhagarika no gutwara umusenyi butwara amazi, kuzamura ibisubizo byo gucukura no kuvunika ibikorwa.

(4) ITERAMBERE RY'ITERAMBERE RYA HEC

Hamwe no gutera imbere ikoranabuhanga nimpinduka kubisabwa ku isoko, igipimo cya ENC gikomeje kwaguka. Icyerekezo cy'iterambere kizaza kirimo:

4.1 Iterambere ryimikorere miremire hec
Mugutezimbere gahunda yo gukora hamwe nibipimo byabigenewe bifatika, hec hamwe nisubukuru yo hejuru, umukecuru kandi hashobora gutezwa imbere kandi hashobora gutezwa imbere kandi hashobora gutezwa imbere kugirango hashobore kubahiriza ibintu bisabwa.

4.2 kurengera ibidukikije n'iterambere rirambye
Gutezimbere ibikorwa byangiza ibidukikije nibikoresho fatizo, kugabanya ibikoreshwa byingufu no gutaka imyanda mugihe cyo kubyara, kandi utezimbere Hec irambye.

4.3 Kwagura imirima mishya
Shakisha ubushobozi bwo gusaba HEC mu mirima y'ibikoresho bishya, inganda zibiribwa no mu bijyanye n'ubuhanga mu bidukikije mu guteza imbere ibyo ushyira mu nganda.

Ultra-Hejuru viccosity hec ni ibintu byinshi bya polymer hamwe nibisabwa mugari. Ibiranga visolique idasanzwe hamwe nubushake bwiza bwa chimique butuma bigira uruhare runini munganda zitandukanye. Hamwe no gutera imbere ikoranabuhanga no kwagura imirima isaba, Isoko rya Hec rizaba rigari.
