Irangi ryatinze (rizwi kandi gushushanya amazi) ni ubwoko bwamazi n'amazi nka solive, bikoreshwa cyane cyane mugushushanya no kurinda urukuta nubundi buso. Formula ya latex irasanzwe ikubiyemo elulsion ya polymer, pigment, filler, inyongeramusaruro nibindi bikoresho. Muri bo,Hydroxyyeryl selile (hec)nibyimbye byingenzi kandi bikoreshwa cyane mumashusho ya latex. HEC ntishobora kunoza viscosiya gusa na rheologiya yirashe, ariko kandi itezimbere imikorere ya firime irangi.
1. Ibiranga ishingiro rya hec
HEC ni kopi ya polymer yoroshye yahinduwe na selile hamwe nibyiza, guhagarika no gukora firime. Urunigi rwayo rufite molekile rurimo amatsinda ya hydroxyyeryl, bituma bishoboza gushonga mumazi no gukora igisubizo kinini. HEC ifite hydrofili gukomeye, ituma igira uruhare mu gutungura, guhindura ibintu no kuzamura imikorere ya firime mu kirato cya latex.
2. Imikoranire hagati ya Hec na Polymer Emulsion
Ikintu cyibanze cya latex irangi ni aside ya Acrymer (nka aside ya acryne-viny acetate emulsion), ikora skeleton nyamukuru ya firime irangi. Imikoranire iri hagati ya Slowl®Hec na Polymer igaragara cyane muri ibi bikurikira:
Guharanira inyungu: Hec, nkumubyimba, birashobora kongera victoity ya latex irangi kandi ifasha gutuza ibice bya emulion. Cyane cyane muri polyment yo hasi-yo kwibandaho, hiyongereyeho HEC irashobora kugabanya imyanda ya emalion ibice kandi itezimbere ububiko bwirashe.
AMABWIRIZA YUBUNTU: HEC irashobora guhindura ibintu byimiterere ya latex irangi, kuburyo ifite imikorere myiza yo kubaka mugihe cyo kubaka. Kurugero, mugihe cyo gushushanya, HEC irashobora kunoza umutungo unyerera h'irangi kandi wirinde gutonyanga cyangwa kunyeganyega. Byongeye kandi, HEC irashobora kandi kugenzura kugarura irangi kandi izamura uburinganire bwa firime irangi.
Uburyo bwo Guhitamo Imikorere: Ongeraho HEC irashobora kunoza guhinduka, guhora no kurwanya ishozi byo kwifuza. Imiterere ya MoleCular ya HEC irashobora gusabana na Elulsion ya Polymer kugirango yongere uburyo rusange bwa firime irangi, bigatuma bitegura bityo bikagutezimbere kuramba.
3. Imikoranire hagati ya Hec na pigment
Pigment mumarangi ya latex ubusanzwe arimo pigment ya anorganicic (nka titanium dioxyde, ifu ya mika, nibindi) na pigment ogh. Imikoranire hagati ya Hec na pigment igaragarira cyane mubice bikurikira:
Gutabira pirme: ingaruka zijimye za HEC zongera vicosity irangi rya latex, rishobora gutatanya ibishushanyo mbonera kandi birinda ibigori cyangwa kugwa. Cyane cyane kubice byiza byingurube, imiterere ya polymer ya HEC irashobora gupfunyika hejuru yingurube kugirango irinde gutandukanya ibice, bityo bigatuma itara rya pisperion hamwe nisoni.
Imbaraga zihuza pigment na film:HecMolekile irashobora kubyara ibishushanyo byumubiri cyangwa ibikorwa bya shimi hamwe nisoni, kuzamura imbaraga zidasanzwe hagati yingurube na firime yo kurohama, kandi wirinde ibintu byo kumena pigment. By'umwihariko mubice byinshi bya latex, HEC irashobora kunoza neza ibijyanye no kurwanya ikirere na UV irwanya pigment kandi ikagura ubuzima bwa serivisi.
4. Imikoranire hagati ya Hec na Filime
Bamwe mu kuzungura (nka calcium carbonate, ifu ya talcum, ibisekuruza byangiza, nibindi) bikunze koroshya irangi ryo kunoza amarangi, batezimbere imbaraga zihishe filte no kongera ibikorwa byibarafu. Imikoranire hagati ya Hec na Fillyrs igaragarira mubice bikurikira:
Guhagarika byuzuza: Hec irashobora gutuma abayunguruzo bongeweho irangi ryatinze muburyo bumwe bwo gutambuka muburyo bwijimye, birinda abahurira gutura. Kubijyanye nubunini bunini, ingaruka zijimye za HEC ni ngombwa cyane cyane, zishobora gukomeza gukomera ku kirangi.
Gloss no gukoraho ku ihite: Ongeraho filers akenshi bigira ingaruka kuri gloss no gukoraho ku ruhu. SlowlyHec irashobora kunoza imikorere yimyitozo yo gupfuka muguhindura kugabana no guteganya kuzumura. Kurugero, gutanyagura imyenda yuzuye bifasha kugabanya ubuso bwa cootelate hejuru no kuzamura igorofa na gloss ya firime.
5. Imikoranire hagati ya Hec hamwe nizindi nguzanyo
Indirimbo ya nyakwigendera ikubiyemo izindi nyandiko, nkaboroga, kubungabunga, abakozi batose, nibindi. Izi mbogamizi zirashobora gusabana na HEC mugihe cyonoza imikorere yirangi:
Imikoranire hagati ya defoamers na Hec: imikorere ya defoamers ni ukugabanya ibibyimba cyangwa ibibyimba mu irangi, kandi ibiranga ubushyuhe bwimbitse bwa hec birashobora kugira ingaruka kuri HEC irashobora kugira ingaruka kuri ECC ishobora kugira ingaruka kubikorwa bya smoames. HEC ikabije irashobora kugora ibicurane kugirango ikureho neza ifuro, bityo bigira ingaruka kumiterere yubuso. Kubwibyo, ingano ya HEC igomba guhuzwa nifirire ya defoamer kugirango igere ku ngaruka nziza.
Imikoranire hagati yo kubungabunga na Hec: Uruhare rw'abihabangamiwe ni ukubuza imikurire ya mikorobe mu gishushanyo no kwagura igihe cyo kubika. Nka polymer karemano, imiterere ya molekele ya HEC irashobora gukorana nuburinganire, bigira ingaruka ku kurwanya ruswa. Kubwibyo, ni ngombwa guhitamo kurinda bihuye na HEC.
Uruhare rwaHecMu irangi rya latex ntabwo aribyimba, ahubwo ni imikoranire ya elulsions, pigment, filers hamwe nizindi nguzanyo zigena imikorere yimikorere ya latex. Slowlyhec irashobora kunoza ibintu byimiterere ya latex irangi rya latex, kunoza ibitagenda neza hamwe numwuka, kandi bizamure imitungo nubuhindure bwimirire. Byongeye kandi, ingaruka za synorgistic za Hec hamwe nizindi nguzanyo nabo bafite ingaruka zikomeye mububiko bwububiko, imikorere yubwubatsi no guhinga biranga irangi rya latex. Kubwibyo, muburyo bwo gushushanya bwa latex, guhitamo neza ubwoko bwa hec hamwe nibyiyongera hamwe nuburinganire bwimikoranire yacyo nibindi bikoresho nurufunguzo rwo kunoza imikorere rusange ya latex irangi muri rusange.
