Methyl hydroxyethyl selulose (MHEC) ningirakamaro ya selile yingenzi ya selile hamwe na modhylation ebyiri na methylation na hydroxyethylation.Mumazi ashingiye kumazi, MHEC igira uruhare runini hamwe nimiterere yihariye yumubiri nubumara.
I. Ibiranga imikorere
Kubyimba
Amatsinda ya hydroxyethyl na methyl mumiterere ya molekulire ya MHEC arashobora gukora imiterere y'urusobe mugisubizo cyamazi, bityo bikongerera neza ubwiza bwikibiriti.Ingaruka yibyibushye ituma igera kuri rheologiya nziza yibitekerezo bike, bityo bikagabanya ingano yo gutwikira no kuzigama amafaranga.
Guhindura imiterere
MHEC irashobora guha igifuniko ibintu byiza kandi birwanya kugabanuka.Ibiranga pseudoplastique bituma igipfundikizo kigira ubukonje bwinshi muburyo buhagaze, kandi ubukonje burashobora kugabanuka mugihe cyo gusaba, ibyo bikaba byoroshye mugukaraba, gutwikisha uruziga cyangwa gutera imiti, kandi amaherezo birashobora kugarura vuba ubwiza bwumwimerere nyuma yubwubatsi ni byuzuye, kugabanya sag cyangwa gutonyanga.
Kubika amazi
MHEC ifite uburyo bwiza bwo gufata amazi kandi irashobora kugenzura neza igipimo cyo kurekura amazi.Uyu mutungo ni ingenzi cyane cyane mukurinda amarangi ashingiye kumazi guturika, ifu nizindi nenge mugihe cyo kumisha, kandi birashobora no kunoza ubwuzuzanye nuburinganire bwikibiriti mugihe cyo kubaka.
Guhagarika umutima
Nka surfactant, MHEC irashobora kugabanya ubukana bwubuso bwibice bya pigment mu marangi ashingiye ku mazi kandi bigateza imbere gukwirakwiza kimwe mu bikoresho fatizo, bityo bikazamura ituze no kuringaniza irangi no kwirinda guhindagurika no kugwa kwa pigment.
Ibinyabuzima
MHEC ikomoka kuri selile isanzwe kandi ifite ibinyabuzima byiza, bigatuma igira ibyiza bigaragara mu marangi ashingiye ku bidukikije kandi ikanafasha kugabanya umwanda ku bidukikije.
2. Ibikorwa by'ingenzi
Thickener
MHEC ikoreshwa cyane cyane mubyimbye bishingiye kumazi kugirango irusheho kunoza imikorere yubwubatsi ndetse nubwiza bwa firime mukongera ububobere bwirangi.Kurugero, kongeramo MHEC kumarangi ya latex birashobora gukora igifuniko kimwe kurukuta kugirango wirinde irangi kugabanuka no kugabanuka.
Umugenzuzi wa Rheologiya
MHEC irashobora guhindura imvugo yubuvanganzo bushingiye kumazi kugirango irebe ko byoroshye kuyikoresha mugihe cyubwubatsi kandi ishobora gusubira muburyo buhamye.Binyuze muri ubwo buryo bwo kugenzura imvugo, MHEC itezimbere neza imikorere yubwubatsi bwa coating, bigatuma ibera inzira zitandukanye.
Umukozi wo kubika amazi
Mu mwenda ushingiye ku mazi, umutungo ugumana amazi wa MHEC ufasha kongera igihe cyo gutura mu mazi, gutwika uburinganire bwumye, kandi bikarinda kubyara ibice ndetse nubuso.
Stabilizer
Bitewe nubushobozi bwiza bwa emulisitiya, MHEC irashobora gufasha gutwikisha amazi gushinga sisitemu ihamye ya emulsiyasi, kwirinda imvura nogukwirakwiza kwingirangingo, kandi bigateza imbere ububiko.
Imfashanyo yo gukora firime
Mugihe cyo gukora firime yo gutwikira, kuba MHEC irashobora guteza imbere uburinganire nubworoherane bwikibiriti, kugirango igifuniko cya nyuma kigaragare neza kandi gikore neza.
3. Ingero zo gusaba
Irangi
Irangi rya latex, umurimo wingenzi wa MHEC nukubyimba no kubika amazi.Irashobora kunoza cyane imiterere yo koza no kuzunguruka irangi rya latex, kandi ikemeza ko igifuniko gikomeza ubworoherane nuburinganire mugihe cyo kumisha.Byongeye kandi, MHEC irashobora kandi kongera uburyo bwo kurwanya no gusasa irangi rya latex, bigatuma inzira yo kubaka igenda neza.
Irangi ryibiti byamazi
Mu irangi ryibiti byamazi, MHEC itezimbere ubwuzuzanye nuburinganire bwa firime irangi muguhindura ubwiza na rheologiya y irangi.Irashobora kandi kubuza irangi gukora kugabanuka no kwangirika hejuru yinkwi, kandi bikongerera imbaraga zo gushushanya no kuramba kwa firime.
Irangi ryubwubatsi
Ikoreshwa rya MHEC mu irangi ryubatswe n’amazi rishobora kunoza imikorere yubwubatsi hamwe nubwiza bwo gusiga irangi, cyane cyane iyo gutwikira hejuru nkurukuta nigisenge, birashobora gukumira neza kugabanuka no gutonyanga irangi.Byongeye kandi, umutungo wo gufata amazi ya MHEC urashobora kandi kongera igihe cyo kumisha irangi, kugabanya gucika nubuso bwubuso.
Irangi ryinganda
Mu irangi ry’inganda zikomoka ku mazi, MHEC ntabwo ikora gusa nk'umubyimba wogukomeza no gufata amazi, ahubwo inatezimbere ikwirakwizwa no gutuza kw'irangi, kugirango irangi rishobore gukomeza gukora neza no kuramba mubidukikije bigoye.
IV.Amahirwe y'isoko
Hamwe n’amabwiriza akomeye yo kurengera ibidukikije no gukenera ibikoresho byubaka icyatsi, isoko ku marangi y’amazi akomeje kwiyongera.Nka nyongera yingenzi mumabara yo mumazi, MHEC ifite isoko ryagutse.
Guteza imbere politiki y’ibidukikije
Ku isi hose, politiki y’ibidukikije yarushijeho gukaza umurego ku byuka bihumanya ikirere (VOC), ibyo bikaba byateje imbere ikoreshwa ry’amazi.Nka nyongeramusaruro yangiza ibidukikije, MHEC igira uruhare runini mugutwikira amazi, kandi ibyifuzo byayo biziyongera hamwe no kwagura isoko ry’amazi.
Kwiyongera gukenewe mu nganda zubaka
Kwiyongera gukenewe kuri VOC nkeya, ikora neza cyane mubikorwa byubwubatsi nabyo byateje imbere ikoreshwa rya MHEC mububiko bwububiko bwamazi.Cyane cyane imbere yimbere ninyuma, MHEC irashobora gutanga imikorere myiza yubwubatsi kandi burambye kugirango isoko ryiyongere.
Kwagura ikoreshwa ryimyenda yinganda
Kwiyongera gukenera kwangiza ibidukikije mu nganda byateje imbere ikoreshwa rya MHEC mu nganda zikomoka ku mazi.Mugihe imyenda yinganda itera imbere yerekeza kubidukikije no gukora cyane, MHEC izagira uruhare runini mugutezimbere imikorere yimiterere nibidukikije.
Methyl hydroxyethyl selulose (MHEC) igira uruhare runini mu gutwikira amazi hamwe no kubyimba kwiza kwinshi, guhindura imvugo, gufata amazi, gutuza kwa emulsiya no kubora ibinyabuzima.Ikoreshwa ryayo mu mazi ashingiye ku mazi ntabwo atezimbere gusa imikorere yubwubatsi hamwe nubwiza bwa coating, ariko kandi bihuza nuburyo bwo kurengera ibidukikije niterambere rirambye.Hamwe nisoko ryiyongera ryisoko ryibikorwa byinshi, bike-VOC bishingiye kumazi, ibyifuzo bya MHEC muriki gice bizaba binini cyane.
