I-Hydroxyethylcellulose (HEC) yepeyinti kunye nezicelo zokugquma

IHydroxyethylcellulose (HEC) yipolymer eguquguqukayo esetyenziswa kakhulu kumashishini ahlukeneyo, ngakumbi kwiipeyinti kunye neengubo.

1. Intshayelelo ngeHydroxyethyl Cellulose (HEC)

Inkcazo kunye nesakhiwo

I-Hydroxyethyl cellulose yi-polymer enganyibiliki emanzini e-nonionic efunyenwe ngokuguqulwa kweekhemikhali zeselulosi. Ubume bayo beekhemikhali bubandakanya iiyunithi eziphindaphindayo zeglucose ezidityaniswe kunye, kunye namaqela e-hydroxyethyl adityaniswe namanye amaqela e-hydroxyl kwiiyunithi zeglucose.

uphawu

Ukunyibilika kwamanzi: Enye yeempawu eziphambili ze-HEC kukunyibilika kwayo okugqwesileyo kwamanzi, okwenza kube lula ukudibanisa kwimiqulu esekwe emanzini.

I-Thickener: I-HEC isebenza njenge-thickener esebenzayo, inika ulawulo lwe-viscosity kwiintlobo ezahlukeneyo zezicelo.

Iipropati zokwenza ifilimu: I-HEC inamandla okwenza ifilimu encedisa ekuphuhliseni iifilimu ezinamathele kunye nezizinzileyo.

Ukuzinza: Ibonisa uzinzo kuluhlu olubanzi lwe-pH kunye nobushushu.

2.Indima ye-HEC ekuqulunqweni kwe-coating

Ukutyeba kunye nolawulo lwe-rheology

I-HEC isetyenziswa ngokubanzi njenge-thickener kwiingubo ezisekelwe emanzini. Inika i-viscosity kwipeyinti, echaphazela ukuhamba kwayo kunye neempawu zokulinganisa. Ukuziphatha kwe-rheological of coatings kubalulekile ukuze kube lula ukusetyenziswa kunye nokwakhiwa kweengubo ezifanayo.

Ukuphucula ukuzinza kwepeyinti

Ukongezwa kwe-HEC kuphucula ukuzinza kweendlela zokugquma ngokuthintela ukuhlalisa okanye ukuthoba. Oku kubaluleke kakhulu kwimixube enomxholo ophezulu we-pigment, apho ukugcina ukusabalalisa ngokulinganayo kunokuba ngumngeni.

Ukuqulunqwa kwefilimu kunye nokunamathela

I-HEC incedisa kwinkqubo yokwenza ifilimu yeengubo. Ipolymer iyoma ukuze yenze ifilimu encangathi ebonelela ngokunamathela kwiindawo ezahlukeneyo. Oku kubalulekile ekomeleleni nasekuphileni ixesha elide lomphezulu opeyintiweyo.

Ukugcinwa kwamanzi

Kwiipeyinti zangaphandle, i-HEC inceda ukugcina amanzi kwaye ikhusela ipeyinti ukuba yome ngokukhawuleza. Oku kubalulekile ukuvumela ipeyinti ukuba iphakame ngokufanelekileyo kwaye ugweme iingxaki ezifana namanqaku ebrashi okanye amanqaku e-roller.

3. Ukusetyenziswa kwe-HEC kwiinkqubo zokugquma

Iingubo zoKwakha

I-HEC isetyenziswa ngokubanzi kwiingubo zokwakha, kubandakanywa iingubo zangaphakathi kunye nezangaphandle zodonga. Inika ulawulo lwe-viscosity, ukuzinza kunye nokukwazi ukwenza ifilimu, okwenza kube yinto ebalulekileyo kwipeyinti eludongeni kunye nokuqulunqwa kwe-primer.

iingubo zokhuni

Kwiingubo zokhuni, i-HEC inceda ukuphuhlisa ukugqitywa okucacileyo kunye neenkuni zokhuni. Inceda ukufezekisa i-viscosity efunekayo kwisicelo esilula kwiindawo zokhuni, iqinisekisa ukugubungela kunye nokugqiba okugudileyo.

Iingubo zamashishini

I-HEC ingasetyenziselwa kwiindidi zeengubo zemizi-mveliso, ezifana nentsimbi kunye neengubo zokukhusela. Iimpawu zayo zokwenza ifilimu kunye nokubambelela kunceda ukudala iingubo ezingenakunqandwa kunye ne-corrosion.

I-inki yokuprinta

I-HEC's versatility idlulela kwii-inki zokuprinta, apho ingasetyenziswa njenge-thickener kwaye incede ukuphucula uzinzo jikelele lwe-inki. Oku kubalulekile ekuphumezeni umgangatho woshicilelo ongaguqukiyo.

IHydroxyethylcellulose idlala indima ebalulekileyo kwishishini lepeyinti kunye neengubo zokwaleka, inika uluhlu lweenzuzo ezibandakanya ukutyeba, ukuzinza, ukwenza ifilimu kunye nokugcinwa kwamanzi. Ukuguquguquka kwayo kwenza ukuba ibe yinto exabisekileyo kwiindidi ezahlukeneyo zokugquma, ukusuka kwizakhiwo ukuya kwimizi-mveliso. Njengoko itekhnoloji iqhubeka nokuhambela phambili, imfuno yeepolymers ezisebenzayo nezisebenzayo ezifana ne-HEC kungenzeka ukuba zinyuke, ziqhubele phambili ukuveliswa kwezinto ezintsha kwicandelo lepeyinti kunye neengubo.
