Hydroxyethylcellulose (HEC) ikoreshwa mu gusiga amarangi

Ibisobanuro:

Hydroxyethylcellulose (HEC) ni polymer itandukanye kandi ifite uburyo bwinshi bwo gukoresha mu nganda zitandukanye, kimwe mu bintu byingenzi ikoreshwa ni ugusiga amarangi. Twinjiye muburyo bwa chimique ya HEC, imiterere ya rheologiya, nuburyo iyi mitungo itanga imiterere yayo ibyiza byihariye.

kumenyekanisha:

Hydroxyethylcellulose (HEC) ni polymer yamazi yamazi akomoka kuri selile, polymer karemano iboneka murukuta rwibimera. HEC ifite imiterere yihariye kubera imiterere yimiti, bigatuma iba nziza mubikorwa bitandukanye byinganda. Mwisi yisi yo gusiga amarangi no gutwikira, HEC igira uruhare runini mukuzamura ibintu byinshi byingenzi nko kugenzura ibicucu, kubika amazi, gukora firime no gutuza muri rusange.

Imiterere yimiti nimiterere ya rheologiya ya HEC:

Gusobanukirwa imiterere yimiti ya HEC ningirakamaro kugirango wumve imikorere yayo mumarangi no gutwikira. HEC ikomoka kuri selile ikoresheje urukurikirane rw'imiti ihindura hydroxyethyl. Kubaho kwaya matsinda biha HEC amazi meza, bigatuma agira akamaro kanini mubikorwa bishingiye kumazi.

Imiterere ya rheologiya ya HEC, cyane cyane ubushobozi bwayo bwo kubyimba, ni ingenzi muburyo bwo gutwikira. HEC ikora nk'imihindagurikire ya rheologiya, igira ingaruka ku myitwarire yimikorere no kwiyegeranya kwifuniko. Uyu mutungo ningirakamaro kugirango wirinde pigment gutuza, urebe neza ko ushyirwa mubikorwa kandi utezimbere ubwishingizi bwiza iyo ushyizweho na brush cyangwa roller.

Gushyira mu bikorwa HEC mu mazi ashingiye ku mazi:

Amazi ashingiye ku mazi ahabwa agaciro kubera ingaruka nke z’ibidukikije hamwe n’ibinyabuzima bihindagurika (VOC). HEC igira uruhare runini muriyi mikorere itanga ituze, kubyimba no kugenzura imvugo. Polimeri ifasha kurinda pigment gutuza mugihe cyo kubika, itanga ubwiza buhoraho, kandi igateza imbere imikorere rusange y irangi. Byongeye kandi, HEC ifasha kongera igihe cyo gufungura, bityo ikongerera igihe cyo gusaba mbere yuko irangi ryuma.

Porogaramu ya HEC muburyo bwo gushingira:

Mugihe amazi ashingiye kumazi yangiza ibidukikije, ibishishwa bishingiye kumashanyarazi biracyagaragara mubikorwa bimwe na bimwe. Guhuza kwa HEC n'amazi n'ibishishwa bituma ihitamo ibintu byinshi kugirango ibishishwa. Muri ubu buryo, HEC ikora nk'ibikoresho, ifasha mugukora film no gufatira hamwe. Ubushobozi bwayo bwo gukomeza kwijimisha hejuru yubushyuhe ningirakamaro kuri sisitemu ishingiye kuri solvent, itanga imikorere ihamye kandi ihamye.

Ifu ya poro na HEC:

Ifu yifu irazwi cyane kuramba, kubungabunga ibidukikije, no koroshya kubishyira mubikorwa. Ongeraho HEC kumpu yifu yongerera imbaraga no kuringaniza ibintu. Polimeri ifasha kugenzura rheologiya yifu yifu, kwemeza firime nziza, imwe mugihe cyo kuyisaba. Amazi meza ya HEC afite akamaro mugikorwa cyo gukora ifu yifu, itanga uburyo bworoshye bwo kwinjiza polymer mubikorwa.

HEC nka stabilisateur hamwe nogukoresha amazi:

Usibye uruhare rwarwo rwo guhindura imvugo no guhuza, HEC ikora nka stabilisateur ikora neza mugushushanya amarangi. Polimeri ifasha mukurinda gutandukanya ibyiciro nubushyuhe, bigira uruhare mubikorwa byigihe kirekire. Byongeye kandi, HEC ikora nkibikoresho bigumana amazi, bigabanya gutakaza ubushuhe mugihe cyumye. Ibi nibyingenzi byingenzi kugirango harebwe neza firime, gufatana hamwe no kuramba.

mu gusoza:

Hydroxyethylcellulose (HEC) ni ibintu byinshi kandi byingenzi muburyo bwo gusiga amarangi. Ihuza ryayo ridasanzwe ryokubura amazi, kugenzura rheologiya, imiterere ya firime hamwe no gutuza kwinshi bituma iba inyongera yingirakamaro muburyo butandukanye. Kuva kumazi ashingiye kumazi kugeza kumashanyarazi ashingiye kumashanyarazi hamwe nifu yifu, HEC igira uruhare runini mugutezimbere imikorere no kwemeza ibicuruzwa byanyuma. Mugihe icyifuzo cyibidukikije byangiza ibidukikije kandi bikora neza bikomeje kwiyongera, ikoreshwa rya HEC rishobora kwaguka, bikarushaho gushimangira umwanya waryo mubikorwa byinganda.
