I-Arhente eQinisayo yokuNqabisa i-Hydroxyethyl Cellulose (HEC)

Iselulosi yeHydroxyethyl(HEC) i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polymer yendalo efumaneka kwizityalo.Isetyenziswa ngokuqhelekileyo njenge-agent exutywayo kwiingubo ezithwala amanzi ngenxa yeempawu zayo ze-rheological, ukuzinza, kunye nokuhambelana neenkqubo ezinamanzi.Nalu ujongo olusondeleyo kwi-HEC njenge-ejenti yokujiya kwiingubo ezihamba emanzini:

Ukusebenza kunye neePropati:

1. Ukuqina: I-HEC isebenza kakhulu ekwandiseni i-viscosity yezisombululo ezinamanzi, kubandakanywa neengubo zokugquma ngamanzi.Ngokunyusa i-viscosity, i-HEC iphucula ukuhamba kunye neempawu zokulinganisa zeengubo, ziphucula iimpawu zabo zesicelo, kwaye zithintele ukuxubha okanye ukuvuza.
2. I-Shear-thinning Behaviour: I-HEC ibonisa ukuziphatha kwe-shear-thinning, oku kuthetha ukuba i-viscosity yayo iyancipha phantsi koxinzelelo lwe-shear (umzekelo, ngexesha lokufaka isicelo), ukuvumela ukusetyenziswa lula kunye nokusabalalisa kwengubo.Emva kokuba uxinzelelo lwe-shear lususiwe, i-viscosity ibuyisela ngokukhawuleza, igcina ubukhulu obufunwayo kunye nokuzinza kwengubo.
3. Ukuzinza: I-HEC inika uzinzo kwiingubo ezithwala amanzi ngokuthintela ukuhlaliswa kwee-pigments kunye nezinye izinto eziqinileyo.Inceda ukugcina ukusabalalisa okufanayo kweengqungquthela kulo lonke ukwakhiwa kweengubo, ukuqinisekisa ukusebenza okuhambelanayo kunye nokubonakala.
4. Ukuhambelana: I-HEC iyahambelana noluhlu olubanzi lwezithako zokugquma, kubandakanywa ii-pigments, iifayili, izibophelelo kunye nezongezo.Ayichaphazeli kakubi ukusebenza okanye iimpawu zamanye amacandelo ekuqulunqweni.
5. Ukugcinwa kwamanzi: I-HEC inokuphucula iimpawu zokugcinwa kwamanzi kwiingubo, ukunciphisa izinga lokunyuka kwamanzi ngexesha lokusetyenziswa kunye nokunyanga.Oku kunokwandisa ixesha lokusebenza kwengubo kunye nokuphucula ukunamathela kwi-substrate.
6. Ukwenziwa kweFilimu: I-HEC inegalelo ekubunjweni kwefilimu efanayo kunye nokuqhubekayo kwi-substrate surface njengoko i-coating yoma.Inceda ukuphucula ukuqina, ukunamathela, kunye neempawu zemishini yefilimu yokugqoka eyomileyo.

Usetyenziso:

1. I-Architectural Coatings: I-HEC isetyenziswa ngokubanzi kwiipeyinti zamanzi kunye neengqungquthela zokwakha ukulawula i-viscosity, ukuphucula iipropati zesicelo, kunye nokuphucula ukubunjwa kwefilimu.Kufanelekile ukusetyenziswa kwiingubo zangaphakathi kunye nezangaphandle, kubandakanywa ii-primers, iipeyinti ze-emulsion, i-textured coatings, kunye nokugqitywa kokuhlobisa.
2. IiNgxoxo zoMzi-mveliso: I-HEC isetyenziswa kwiingubo ezahlukeneyo zemizi-mveliso, ezinje ngeemoto ezityabekayo, iileyiti zokhuni, iingubo zentsimbi, kunye neengubo ezikhuselayo.Inceda ukufezekisa iipropati ezifunwayo ze-rheological, ubukhulu befilimu, kunye nenkangeleko yomphezulu kwezi zicelo.
3. Imichiza yokwakha: I-HEC iqeshwe kwiikhemikhali zokwakha, kubandakanywa ukugquma kwamanzi, ii-sealants, i-adhesives, kunye ne-tile grouts.Inika ukutyeba kunye nokuzinzisa kolu qulunqo, ukuphucula ukusebenza kunye nokusebenza.
4. Iingubo zePhepha: Kwiingubo zephepha kunye nonyango oluphezulu, i-HEC isetyenziselwa ukunyusa iimpawu ze-rheological ze-coating formulations, ukuphucula umgangatho wokushicilela, kunye nokunyusa i-inki yokubamba kwiphepha lephepha.
5. Iingubo zoMlaphu: I-HEC isetyenziswa kwiingubo ezilukiweyo kwaye igqibezela ukunika ukuqina, ukugxotha amanzi, kunye nokuxhathisa imibimbi kumalaphu.Inceda ukulawula i-viscosity ye-coating formulations kunye nokuqinisekisa ukusetyenziswa okufanayo kwi-textile substrate.

I-hydroxyethyl cellulose (HEC) isebenza njenge-agent eguquguqukayo kunye nesebenzayo yokuqina emanzini, ibonelela ngolawulo lwe-viscosity, ukuzinza, ukugcinwa kwamanzi, kunye neempawu zokubumba ifilimu eziyimfuneko ekufezekiseni ukusebenza okufunayo kunye nokubonakala.
