IHydroxyethylcellulose (HEC) upende kanye nezicelo zokumboza

IHydroxyethylcellulose (HEC) iyipolymer eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene, ikakhulukazi kumapende nezingubo.

1. Isingeniso se-Hydroxyethyl Cellulose (HEC)

Incazelo kanye nesakhiwo

I-Hydroxyethyl cellulose iyi-polymer engancibiliki emanzini e-nonionic etholwe ngokuguqulwa kwamakhemikhali e-cellulose.Isakhiwo sayo samakhemikhali siqukethe amayunithi eglucose aphindaphindayo axhunywe ndawonye, ​​namaqembu e-hydroxyethyl axhunywe kwamanye amaqembu e-hydroxyl kumayunithi e-glucose.

isici

Ukunyibilika Kwamanzi: Enye yezinto ezibalulekile ze-HEC ukuncibilika kwayo okuhle kakhulu kwamanzi, okwenza kube lula ukuhlanganisa ukwakheka okusekelwe emanzini.

I-Thickener: I-HEC isebenza njenge-thickener ephumelelayo, inikeza ukulawula kwe-viscosity ezinhlelweni ezihlukahlukene.

Izakhiwo zokwakha ifilimu: I-HEC inamandla okwenza ifilimu asiza ekuthuthukisweni kwamafilimu anamathelayo naqinile.

Ukuzinza: Kubonisa ukuzinza phezu kwebanga elibanzi le-pH nezinga lokushisa.

2.Iqhaza le-HEC ekwakhiweni kwe-coating

Ukulawula ukuqina kanye ne-rheology

I-HEC isetshenziswa kabanzi njenge-thickener kuma-coatings asekelwe emanzini.Inikeza i-viscosity kupende, ithinta ukugeleza kwayo kanye nezakhiwo zokulinganisa.Ukuziphatha kwe-rheological of coatings kubalulekile ukuze kube lula ukusetshenziswa kanye nokwakhiwa kwezingubo ezifanayo.

Thuthukisa ukuqina kwepende

Ukwengezwa kwe-HEC kuthuthukisa ukuzinza kokwakheka kwe-coating ngokuvimbela ukuzinza noma ukuwohloka.Lokhu kubaluleke kakhulu ekwakhiweni okunokuqukethwe okuphezulu kwe-pigment, lapho ukugcinwa kokusabalalisa okulinganayo kungaba inselele.

Ukwakhiwa kwefilimu nokunamathela

I-HEC isiza enqubweni yokwenza ifilimu yokumboza.I-polymer iyoma ukuze yakhe ifilimu enamathelayo ehlinzeka ngokunamathela ezindaweni ezihlukahlukene.Lokhu kubalulekile ekuqineni nasekuphileni isikhathi eside kwendawo ependiwe.

Ukugcinwa kwamanzi

Kupende wangaphandle, i-HEC isiza ekugcineni amanzi futhi ivimbele upende ukuthi lome ngokushesha.Lokhu kubalulekile ukuvumela upende ukuthi uleveli ngendlela efanele futhi ugweme izinkinga ezifana namamaki ebhulashi noma ama-roller mark.

3. Ukusetshenziswa kwe-HEC ezinhlelweni zokumboza

I-Architectural Coatings

I-HEC isetshenziswa kabanzi ekwakhiweni kwezakhiwo, kufaka phakathi udonga lwangaphakathi nangaphandle.Ihlinzeka ngokulawula i-viscosity, ukuzinza kanye namakhono okwenza ifilimu, okwenza kube isithako esibalulekile ekwenziweni kopende odongeni kanye ne-primer.

izingubo zokhuni

Ezingubo zokhuni, i-HEC isiza ukuthuthukisa ukuqedwa okucacile namabala okhuni.Isiza ukufeza i-viscosity edingekayo ukuze kube lula ukusetshenziswa ezindaweni zokhuni, iqinisekisa ukumbozwa nokuqeda okubushelelezi.

Izingubo zezimboni

I-HEC ingasetshenziswa ezinhlobonhlobo zezimboni zezimboni, ezifana nezinsimbi zensimbi nezivikelayo.Izakhiwo zayo zokwenza ifilimu nokunamathela kusiza ekwakheni ama-coatings amelana nokugqwala futhi ahlala isikhathi eside.

Uyinki wokuphrinta

Ukuhlukahluka kwe-HEC kudlulela koyinki bokuphrinta, lapho ingasetshenziswa khona njengesigqinsi futhi isize ukuthuthukisa ukuzinza kukonke kukayinki.Lokhu kubalulekile ukuze kuzuzwe ikhwalithi yokuphrinta engaguquki.

I-Hydroxyethylcellulose idlala indima ebalulekile embonini kapende neyokumboza, inikeza izinzuzo eziningi ezihlanganisa ukujiya, ukuzinza, ukwenza ifilimu nokugcinwa kwamanzi.Ukuguquguquka kwayo kuyenza ibe isithako esibalulekile ezinhlotsheni ezihlukene zokumboza, kusukela ekwakhiweni kwezakhiwo kuya kwezimbozwe zezimboni.Njengoba ubuchwepheshe buqhubeka buthuthuka, isidingo sama-polymers asebenza kahle futhi asebenza ngezinto eziningi njenge-HEC kungenzeka sikhule, siqhubekisele phambili ukuqamba okusha emkhakheni wamapende nezingubo.
