Hydroxyethyl selulose (HEC) ninyongera yingirakamaro mumazi ashingiye kumazi ya latx, agira uruhare mubintu bitandukanye byerekana irangi. Iyi polymer itandukanye, ikomoka kuri selile, itanga inyungu nyinshi zizamura ubwiza nimikorere yamabara ya latex.
1.Iriburiro rya HEC:
Hydroxyethyl selulose ni ionic, polymer-soluble polymer ikomoka kuri selile ikoresheje guhindura imiti. Ikoreshwa cyane mu nganda zinyuranye, zirimo amarangi no gutwikira, kwisiga, imiti, nibikoresho byubwubatsi, kubera imiterere yihariye. Mu rwego rwo gusiga amarangi ashingiye ku mazi, HEC ikora nk'inyongeramusaruro myinshi, itanga igenzura rya rheologiya, imiterere yibyibushye, hamwe no gutuza kubikorwa.
1.Uruhare rwa HEC muburyo bwa Latex bushingiye kumazi:
Igenzura rya Rheologiya:
HEC igira uruhare runini mugucunga imiterere ya rheologiya yamabara ashingiye kumazi. Muguhindura ubunini bwa HEC, abakora amarangi barashobora kugera kubwiza bwifuzwa no kwitwara neza.
Kugenzura neza imvugo yemeza neza ko irangi rishobora gukoreshwa neza kandi neza ku buso butandukanye, bikazamura uburambe bwabakoresha.
Umubyimba:
Nkumubyimba, HEC yongerera ubwiza bwimyenda ya latex. Ingaruka yo kubyimba irinda kugabanuka cyangwa gutonyanga mugihe cyo gusaba, cyane cyane hejuru yubutumburuke.
Byongeye kandi, HEC itezimbere ihagarikwa ryibara ryuzuza irangi, irinda gutuza no kwemeza ibara rimwe.
Stabilisateur:
HEC igira uruhare mu gutuza igihe kirekire cy’amazi ashingiye ku marangi mu gukumira ibice no gutandukana.
Ubushobozi bwayo bwo gukora sisitemu ihamye ya colloidal yemeza ko ibice bigize irangi bikomeza gutatana kimwe, ndetse no mugihe cyo kubika no gutwara.
Kubika Amazi:
HEC ifite uburyo bwiza bwo kubika amazi, bigira akamaro mugihe cyo kumisha amarangi ya latex.
Mu kugumana amazi muri firime irangi, HEC iteza imbere gukama kimwe, kugabanya gucika cyangwa kugabanuka, kandi byongera gukomera kuri substrate.
Imiterere ya firime:
Mugihe cyo gukama no gukiza, HEC igira uruhare mumashusho ya firime ya latex.
Itanga umusanzu mugutezimbere firime ihamye kandi iramba, itezimbere imikorere rusange no kuramba.
Ibyiza bya HEC:
Amazi meza:
HEC irashobora gushonga byoroshye mumazi, ituma byoroha kwinjizwa mumazi ashingiye kumazi.
Gukemura kwayo byorohereza gutandukana muri matrike yo gusiga irangi, byemeza imikorere ihamye.
Kamere itari Ionic:
Nka polymer itari ionic, HEC irahuza nibindi bintu bitandukanye byongera amarangi nibindi bikoresho.
Kamere yayo itari ionic igabanya ibyago byo gukorana kwifuzwa cyangwa guhungabanya irangi.
Kugenzura Viscosity:
HEC yerekana ibyiciro byinshi byamanota, yemerera abakora amarangi guhuza imiterere ya rheologiya bakurikije ibisabwa byihariye.
Ibyiciro bitandukanye bya HEC bitanga urwego rutandukanye rwo kubyibuha neza hamwe no kwitwara neza.
Guhuza:
HEC irahujwe nubwoko butandukanye bwibigize amarangi, harimo latex binders, pigment, biocide, hamwe nubushakashatsi.
Ihuza ryayo ryongerera ubumenyi bwamazi ashingiye kumazi ya latx, ashoboza iterambere ryibicuruzwa byabigenewe kubikorwa bitandukanye.
3.Ibisabwa bya HEC mu mazi ashingiye ku mazi ya Latex:
Irangi ryimbere ninyuma:
HEC ikoreshwa haba mumazi ninyuma yamazi ashingiye kumarangi ya latx kugirango agere kubintu byiza bya rheologiya nibikorwa.
Iremeza gukoreshwa neza, gukwirakwiza kimwe, no kuramba kuramba.
Kurangiza:
Muburyo bwo gusiga irangi, HEC igira uruhare muguhuza no gukora kubicuruzwa.
Ifasha mukugenzura imiterere yimiterere nuburyo bwo gushushanya, kwemerera kurema ubuso bwifuzwa burangira.
Primer and Undercoat Formulations:
HEC yinjijwe muburyo bwa primer na koti kugirango yongere imbaraga, iringaniza, hamwe nubushyuhe.
Itera imbere gushiraho urwego rwibanze kandi ruhamye, rutezimbere muri rusange hamwe nigihe kirekire cyibara risize.
Impuzu zihariye:
HEC isanga porogaramu zambaye imyenda yihariye, nk'ibara risiga umuriro, irangi rirwanya ruswa, hamwe na VOC nkeya.
Ubwinshi bwayo nibikorwa byongera imikorere bituma iba inyongera yagaciro mumasoko atandukanye niche muruganda.
4.Ibyiza byo gukoresha HEC mumashusho ashingiye kumazi ya Latex:
Kunoza ibyifuzo bya porogaramu:
HEC itanga uburyo bwiza bwo gutondeka no kuringaniza amarangi ya latx, kwemeza neza kandi neza.
Igabanya ibibazo nkibimenyetso byohanagura, gukinisha uruziga, hamwe nuburinganire butaringaniye, bikavamo ubuziranenge bwumwuga.
Kongera imbaraga hamwe nubuzima bwa Shelf:
Kwiyongera kwa HEC byongera ituze nubuzima bwubuzima bwamazi ashingiye kumazi ya latx mukurinda gutandukanya ibyiciro no gutembera.
Irangi ryerekana amarangi arimo HEC rikomeza kuba umwe kandi rikoreshwa mugihe kirekire, kugabanya imyanda no kwemeza ubusugire bwibicuruzwa.
Guhitamo:
Abakora amarangi barashobora guhitamo imiterere ya rheologiya ya latex muguhitamo icyiciro gikwiye hamwe na concentration ya HEC.
Ihinduka ryemerera iterambere ryibisobanuro byujuje ibyangombwa bisabwa hamwe nibisabwa.
Igisubizo cyangiza ibidukikije:
HEC ikomoka ku masoko ya selile ashobora kuvugururwa, bigatuma iba inyongera irambye kandi yangiza ibidukikije ku marangi ashingiye ku mazi.
Ibinyabuzima byangiza kandi bifite ubumara buke bigira uruhare mu kubungabunga ibidukikije byangiza amarangi ya latex, bigahuza n’ibipimo byubaka ibyatsi.
Hydroxyethyl selulose (HEC) igira uruhare runini mugushushanya amarangi ya latx ashingiye kumazi, itanga igenzura rya rheologiya, kubyimba ibintu, gutuza, nibindi byiza byongera imikorere. Guhindura byinshi, guhuza, hamwe n’ibidukikije byangiza ibidukikije bituma byongerwaho byongewe kubakora amarangi bashaka kubyara ibicuruzwa byiza byujuje ubuziranenge kubikorwa bitandukanye. Mugusobanukirwa imiterere nibisabwa bya HEC, abakora amarangi barashobora guhindura uburyo bwabo kugirango bahuze ibikenerwa ninganda zikora.
