Ukusetshenziswa kwe-hydroxyethyl celtuleose kuzimbali

I-Hydroxyyethyl cellulose (HEC)Ingabe i-polymer eguquguqukayo isetshenziswe kabanzi kwizimboni ezahlukahlukene ngenxa yokuqina kwayo, izinzilo, kanye nezakhiwo ezenziwe ngefilimu. Esikhathini sezinkomba, i-HEC idlala indima ebalulekile ekuthuthukiseni i-viscosity, ithuthukisa ukwakheka kwama-heecological, futhi idingida umthelela ophakeme we-hec ekusebenzeni kwe-coating, okufana nokumelana, nokunamathela.

Isingeniso:

I-Hydroxyyethyl cellulose (HEC) yi-nonic, i-polymer esolulekayo yamanzi etholakala ku-cellulose ngokuguqulwa kwamakhemikhali. Kusetshenziswa kabanzi kwizimboni ezahlukahlukene ezinjengemithi, ukunakekelwa komuntu siqu, ukwakhiwa kanye nokumbona ngenxa yezakhiwo zayo ezihlukile. Esikhathini se-coatings, i-hec isebenza imisebenzi eminingi, kufaka phakathi ukuqina, ukuzinza, nokuhlinzeka ngezakhiwo ezenziwe ngefilimu. Le ndatshana igxile ekusetshenzisweni kwe-HEC in Coatings futhi ihlole umthelela wayo ekusebenzeni kwe-coating.

Izicelo ze-HEC in Coatings:

Umenzeli wokuqina:
I-HEC isebenza njenge-ejenti yokuqina esebenzayo ekusungulweni kwezembatho. Ngokwengeza i-viscosity yesisombululo se-coating, i-HEC ithuthukisa ukuqina kwemibala kanye nezithasiselo, ukuvikela ukulungisa noma i-syneresis ngesikhathi sesitoreji kanye nesicelo. I-viscosity ye-coating ingashintshwa ngokuhlukahlukana kwe-hec, okuvumela ukwakheka okuhambisana nakho ukufeza izidingo ezithile zohlelo lokusebenza. Ngokwengeziwe, i-HEC ihlinzeka ngokuziphatha kwe-pseudoplastic, okusho ukuthi kukhombisa ukubonwa okuncishisiwe ngaphansi kwe-shear, lula ukusetshenziswa okulula kanye nokufakwa kwezinga lokuhlanganiswa.

Isitholi se-Rheology:
Ngaphezu kokuqina, i-HEC isebenza njengesiguquli se-Rheology kuma-coatings activation. Ithonya ukusebenza kokugeleza kokuhlanganiswa, ukuthuthukisa izakhiwo zohlelo lokusebenza okufana nokudramatity, ukufafaza, kanye ne-roller-coatmability. I-HEC inika amandla okunciphisa ukuncipha kokuhlanganiswa, okuvumela uhlelo lokusebenza olubushelelezi ngenkathi kugcinwa khona ukuhlakanipha lapho kususwa amandla we-shear. Le mpahla inenzuzo ikakhulukazi ekunciphiseni ukucwilisa ngesikhathi sokufafaza isifutho kanye nokuqinisekisa ukumbozwa okufanayo kwezindawo ezifanayo ngamaphrofayili angaphansi.

Ifilimu langaphambili:
I-HEC inikela ekwakhekeni kwefilimu eqhubekayo neyunifomu endaweni engaphansi komhlaba. Njengoba owomile we-coating, ama-molecule we-hec avumelanisa ukudala isakhiwo sefilimu esihlangene, enikeza ukunamathela okuhle kakhulu ku-substrate kanye nokwenza ngcono ukuqina kokuhlanganiswa. Izakhiwo ezenziwe ngefilimu zika-HEC zibalulekile ekufezekiseni izici ezifiselekayo ezifana nobulukhuni, ukuvumelana nezimo kanye nokumelana nesimo sezulu. Ngaphezu kwalokho, amafilimu we-HEC abonisa ukumelana kwamanzi okuhle, okwenza balungele izimbotshana ezivezwe umswakama noma izindawo eziphezulu zomswakama.

Umthelela we-HEC ekusebenzeni kwe-coating:

Ukulawulwa Kwe-Viscosity:
I-HEC inika amandla okulawula okuqondile ngaphezulu kokuvunywa kwezimbozo, uqinisekise ukugeleza okuphezulu nokugeleza kwezimpawu. Ukuphathwa okufanelekile kwe-viscosity kuvimbela izingqinamba ezifana nezinkinga, ukudonsa, noma ukumboza okungalingani ngesikhathi kusetshenziswa ikhwalithi ye-coating ethuthukisiwe kanye nama-aesthetics. Ngaphezu kwalokho, ukusebenza okunciphise ukuncipha kwe-hec kusiza uhlelo lokusebenza olulula ngaphandle kokuyekethisa ukusebenza kwe-coating.

Ukumelana nokumelana nokuqina kwe-SAG:
Izakhiwo ezibhekwayo ezifakwe yi-HEC zinikela ngenjongo yokumelana kahle nokumelana kwezimbambo. Ngesikhathi sokwenziwa, i-HEC inciphisa ukuthambekela kokuhlanganiswa kokwakha amamaki okuxubha noma ama-roller stifel, okuholela ekugcineni okubushelelezi futhi okufanayo. Ngokwengeziwe, i-HEC ithuthukisa ukusebenza kwe-Thixotropic kwezimbozo, ukuvimbela ukugcwala noma ukudonsa ezindaweni ezibheke phezulu, ngaleyo ndlela kuthuthukise ukusebenza kahle kohlelo lokusebenza kanye nokunciphisa imfucuza yezinto ezibonakalayo.

Adhesion:
I-HEC ithuthukisa ukunamathela kwezimbozo eziya ezingxenyeni ezahlukahlukene, kufaka phakathi izinsimbi, izinkuni, amapulasitiki nokhonkolo. Izakhiwo ezenziwe ngefilimu zika-HEC zakha isibopho esiqinile phakathi kokuhlanganiswa kanye ne-substrate, ngcono ukunamathela kwesikhathi eside nokuqina. Lokhu kubaluleke kakhulu ezitsheni zangaphandle ezivezwa izimo zemvelo ezinokhahlo, lapho ukunamathela kudlala indima ebalulekile ekuvikeleni ukwehluleka ukunamathela okufana nokukhohlisa.

Intuthuko kubuchwepheshe be-HEC:

Ukuthuthuka kwakamuva kuI-HECUbuchwepheshe buholele ekuthuthukisweni kokutholwa kwe-HEC okuguquliwe ngezimpawu zokusebenza ezithuthukisiwe. Lokhu kulungiswa kufaka phakathi ukwehluka kwesisindo samangqamuzana, izinga lokufaka esikhundleni, nesakhiwo samakhemikhali, okuvumela izixazululo ezihambisana nazo ukuze zihlangabezane nezidingo ezithile zohlelo lokusebenza. Ngokwengeziwe, i-Resea

Imizamo ye-RCH igxile ekuthuthukiseni ukuqina kwemvelo kwezinqubo zokukhiqiza ze-HEC, okuholela ekuqubukeni kwe-HEC esekelwe eBio kusuka kwimithombo evuselelekayo efana ne-cellulose kusuka ku-biomass yesitshalo.

Amathrendi asafufusa kuhlelo lokusebenza lwe-HEC ku-Coatings:

Ukuqanjwa Kwemvelo Kwemvelo:
Ngokugcizelela okwandayo kokusimama kanye nemithetho yezemvelo, kunesidingo esikhulayo sezakhiwo ze-Coatings ezisebenzisa izengezo ze-eco-friendly ezinjengoHec. I-HEC esekelwe eBio esuselwa kwimithombo evuselelekayo inikeza enye indlela eqhubekayo ku-polymers esuselwa ku-petroleum, ukunciphisa umthelela wekhabhoni kanye nomthelela wezemvelo.

Imbobo yokusebenza ephezulu:
Isidingo sokugqoka okuphezulu kokusebenza okuphezulu ngokuqina okuphezulu, ukumelana nesimo sezulu, kanye nezakhiwo zobuhle zishayela ukwamukelwa kwezithasiselo ezithuthukile ezinjenge-hec. Amakhemikhali ahlola izindlela ezintsha zokuthuthukisa ukusebenza kwezimbozo ezisebenzisa izinsiza ezenzelwe i-HEC, ukunakekela izicelo ezahlukahlukene ezisukela ekupekeni kwezokwakha ezimotweni zezimoto.

Digital Coating Technologies:
Intuthuko kubuchwepheshe be-Digital Coating Technologies, njengokuphrinta kwe-inkjet kanye nokufanisa kombala wedijithali, amathuba amasha akhona okusetshenziswa kwe-HEC ngezingubo. Izakhi ezisuselwa ku-HEC zingalungiselelwe ukuhambisana nezinqubo zokuphrinta zedijithali, kunika amandla ukulawulwa okuqondile kokuthola impahla ye-coating kanye nokwenza ngcono ukuphrinta kwekhwalithi nokunemba kwemibala.

I-Hydroxyyethyl cellulose (HEC)Udlala indima ebalulekile ekuthuthukiseni ukusebenza kwezimbozo ngokusebenza njengesikhulu, i-Rheology modifier, kanye nefilimu yangaphambili. Izakhiwo zayo ezihlukile zinika amandla okulawula okuqondile ngokusobala, ukuvelela okuhle kakhulu, ukumelana okuhle, nokulinganiselwa okuphezulu ku-substrates. Intuthuko yakamuva kubuchwepheshe be-HEC kanye nezitayela ezivelayo kuhlelo lokusebenza lwayo lugcizelela ukubaluleka kwalo njengezengezo eziguquguqukayo ekusungulweni kwezembatho. Njengoba imboni ye-Coatings iqhubeka nokuvela, i-HEC ilungele ukuhlala isakhi esiyinhloko ekuthuthukisweni kwezixazululo ezisezingeni eliphakeme, ezisimeme zentela.
