Imikoranire hagati ya HEC nibindi bikoresho mu irangi rya latex

Irangi rya Latex (rizwi kandi nk'irangi rishingiye ku mazi) ni ubwoko bw'irangi rifite amazi nk'ibishishwa, bikoreshwa cyane cyane mu gushushanya no kurinda inkuta, igisenge n'ahandi hantu. Inzira yo gusiga irangi rya latx mubisanzwe irimo polymer emuliyoni, pigment, yuzuza, inyongeramusaruro nibindi bikoresho. Muri bo,hydroxyethyl selulose (HEC)ni umubyimba wingenzi kandi ukoreshwa cyane mumarangi ya latex. HEC ntishobora gusa kunoza ubwiza na rheologiya y'irangi, ariko kandi irashobora kunoza imikorere ya firime.

1. Ibiranga shingiro bya HEC
HEC ni amazi ya elegitoronike ya polymer ivanze kuva muri selile hamwe no kubyimba neza, guhagarikwa no gukora firime. Urunigi rwarwo rurimo amatsinda ya hydroxyethyl, ayifasha gushonga mumazi no gukora igisubizo cyinshi cyane. HEC ifite hydrophilicity ikomeye, iyifasha kugira uruhare muguhagarika ihagarikwa, guhindura imvugo no kunoza imikorere ya firime mumarangi ya latex.

2. Imikoranire hagati ya HEC na polymer emulion
Ibyingenzi bigize irangi rya latex ni polymer emuliyoni (nka acide acrylic cyangwa Ethylene-vinyl acetate copolymer emulsion), ikora skeleti nyamukuru ya firime. Imikoranire hagati ya AnxinCel®HEC na emulion ya polymer igaragara cyane mubice bikurikira:

Kunoza umutekano: HEC, nkikibyimbye, irashobora kongera ububobere bwirangi rya latex kandi igafasha guhagarika uduce duto twa emulsiyo. Cyane cyane muri emulisiyo nkeya ya polymer, kwiyongera kwa HEC birashobora kugabanya kugabanuka kwimyunyu ngugu no kunoza ububiko bwirangi.

Amabwiriza ya Rheologiya: HEC irashobora guhindura imiterere ya rheologiya yamabara ya latex, kugirango igire imikorere myiza yo gutwika mugihe cyo kubaka. Kurugero, mugihe cyo gushushanya, HEC irashobora kunoza imitungo yo kunyerera irangi kandi ikirinda gutonyanga cyangwa kugabanuka. Byongeye kandi, HEC irashobora kandi kugenzura kugarura irangi no kuzamura uburinganire bwa firime.

Gukwirakwiza imikorere yimyenda: Kwiyongera kwa HEC birashobora kunoza imiterere, ubwiza bwabyo hamwe no guhangana nigitambara. Imiterere ya molekuline ya HEC irashobora gukorana na polymer emulsion kugirango yongere imiterere rusange ya firime irangi, bigatuma irushaho gukomera bityo ikazamura igihe kirekire.

3. Imikoranire hagati ya HEC na pigment
Ibara ryirangi rya latx mubisanzwe ririmo pigment organic organique (nka dioxyde de titanium, ifu ya mika, nibindi) hamwe nibimera kama. Imikoranire hagati ya HEC na pigment igaragara cyane mubice bikurikira:

Ikwirakwizwa rya pigment: Ingaruka yibyibushye ya HEC yongerera ubwiza bwirangi rya latex, ishobora gukwirakwiza neza uduce duto twa pigment kandi ikirinda kwegeranya pigment cyangwa imvura. By'umwihariko kuri bimwe mubice byiza bya pigment, imiterere ya polymer ya HEC irashobora kuzinga hejuru ya pigment kugirango irinde igiteranyo cyibice bya pigment, bityo bitezimbere ikwirakwizwa rya pigment hamwe nuburinganire bwirangi.

Imbaraga zihuza hagati ya pigment na firime:HECmolekile irashobora kubyara adsorption yumubiri cyangwa ibikorwa bya chimique hamwe nubuso bwa pigment, bikongerera imbaraga guhuza hagati ya pigment na firime, kandi birinda ibintu byo kumena pigment cyangwa gushira hejuru ya firime. Cyane cyane mugukora irangi ryinshi rya latex, HEC irashobora kunoza neza guhangana nikirere hamwe na UV irwanya pigment kandi ikongerera igihe cyo gukora.

4. Imikoranire hagati ya HEC n'abayuzuza
Bimwe mu byuzuza (nka calcium karubone, ifu ya talcum, imyunyu ngugu ya silikatike, nibindi) mubisanzwe byongewe kumarangi ya latex kugirango tunonosore imvugo y irangi, kunoza imbaraga zo guhisha firime yo gutwikira no kongera ibiciro-bikora neza. Imikoranire hagati ya HEC niyuzuza igaragarira mubice bikurikira:

Ihagarikwa ryuzuza: HEC irashobora gutuma abuzuza bongerwaho irangi rya latex muburyo bumwe bwo gutatanya binyuze muburyo bwo kubyimba, bikabuza abuzuza gutura. Kubuzuza ubunini bunini, ingano ya HEC ningirakamaro cyane, ishobora gukomeza neza irangi.

Kurabagirana no gukoraho igifuniko: Kwiyongera kwuzuza akenshi bigira ingaruka kumurabyo no gukorakora. AnxinCel®HEC irashobora kunoza imikorere yimyenda ihindura ikwirakwizwa nogutunganya ibyuzuye. Kurugero, gukwirakwiza kimwe kwuzuza ibice bifasha kugabanya ubukana bwubuso bwa coating no kunoza uburinganire nuburabyo bwa firime irangi.

5. Imikoranire hagati ya HEC nibindi byongeweho
Irangi rya latex ririmo kandi izindi nyongeramusaruro, nka defoamers, preservatives, agent wetting, etc.

Imikoranire hagati ya defoamers na HEC: Igikorwa cyo gusebanya ni ukugabanya ibibyimba cyangwa ifuro mu irangi, kandi ibintu byinshi biranga ubwiza bwa HEC bishobora kugira ingaruka ku ngaruka zangiza. HEC ikabije irashobora kugora defoamer gukuraho burundu ifuro, bityo bikagira ingaruka kumiterere y irangi. Kubwibyo, umubare wa HEC wongeyeho ugomba guhuzwa numubare wa defoamer kugirango ugere ku ngaruka nziza.

Imikoranire hagati yokwirinda na HEC: Uruhare rwokwirinda ni ukurinda imikurire ya mikorobe mu irangi no kongera igihe cyo kubika irangi. Nka polymer karemano, imiterere ya molekile ya HEC irashobora gukorana nuburinzi bumwe na bumwe, bikagira ingaruka ku kurwanya ruswa. Kubwibyo, ni ngombwa guhitamo imiti igabanya ubukana ijyanye na HEC.

Uruhare rwaHECirangi rya latex ntabwo ryiyongera gusa, ahubwo imikoranire yaryo na emulisiyo ya polymer, pigment, yuzuza nibindi byongeweho hamwe bigena imikorere y irangi rya latex. AnxinCel®HEC irashobora kunoza imiterere ya rheologiya yamabara ya latex, igatezimbere itandukanyirizo ryibintu byuzuza, kandi ikazamura imiterere yubukanishi nigihe kirekire cyo gutwikira. Mubyongeyeho, ingaruka zo guhuza HEC nizindi nyongeramusaruro nazo zigira ingaruka zikomeye kububiko butajegajega, imikorere yubwubatsi no gutwikira isura ya latex. Kubwibyo, mugushushanya amarangi ya latex, guhitamo neza ubwoko bwa HEC nubwinshi bwinyongera hamwe nuburinganire bwimikoranire nibindi bikoresho nurufunguzo rwo kuzamura imikorere rusange y irangi rya latex.
