Ukusetyenziswa kwe-Hydroxyethyl Cellulose kwiiCoatings

Iselulosi yeHydroxyethyl (HEC)yipolymer eguquguqukayo esetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokuqina kwayo okugqwesileyo, ukuzinzisa, kunye neempawu zokwenza ifilimu. Kwindawo yokugqoka, i-HEC idlala indima ebalulekileyo ekuphuculeni i-viscosity, ukuphucula iimpawu ze-rheological, kunye nokubonelela ngefilimu ephezulu yokuqulunqa.

Intshayelelo:

I-Hydroxyethyl cellulose (HEC) i-non-ionic, i-polymer e-soluble yamanzi ephuma kwi-cellulose ngokuguqulwa kweekhemikhali. Isetyenziswa ngokubanzi kumashishini ahlukeneyo afana namayeza, ukhathalelo lomntu, ulwakhiwo, kunye neengubo ngenxa yeempawu zayo ezizodwa. Kwindawo yokwaleka, i-HEC isebenza ngemisebenzi emininzi, kubandakanywa ukuqina, ukuzinzisa, kunye nokubonelela ngeempawu zokwenza ifilimu. Eli nqaku ligxininise kwizicelo ze-HEC kwiingubo kwaye iphonononga impembelelo yayo ekusebenzeni kombane.

Usetyenziso lwe-HEC kwiiCoatings:

Iarhente yokutyebisa:
I-HEC isebenza njenge-ejenti yokuqina esebenzayo kwiifom ze-coatings. Ngokwandisa i-viscosity yesisombululo sokugubungela, i-HEC iphakamisa ukuzinza kwee-pigments kunye nezongezo, ukukhusela ukuhlalisa okanye i-syneresis ngexesha lokugcinwa kunye nesicelo. I-viscosity ye-coating inokulungelelaniswa ngokutshintsha ukugxininiswa kwe-HEC, ukuvumela ukuqulunqwa okulungiselelwe ukuhlangabezana neemfuno ezithile zesicelo. Ukongezelela, i-HEC inikezela ngokuziphatha kwe-pseudoplastic, oku kuthetha ukuba ibonisa i-viscosity eyanciphayo phantsi kwe-shear, iququzelela ukusetyenziswa okulula kunye nokulinganisa kwengubo.

Isilungisi seRheology:
Ukongeza kokuqina, i-HEC isebenza njenge-rheology modifier kwi-coatings formulations. Ichaphazela indlela yokuhamba kwengubo, ukuphucula iimpawu zesicelo ezifana nokuxubha, ukutshiza, kunye ne-roller-coatability. I-HEC inikezela ngokuziphatha kwe-shear-thinning kwi-coating, ivumela ukusetyenziswa kakuhle ngelixa igcina i-viscosity xa i-shear force isusiwe. Lo mhlaba uluncedo kakhulu ekunciphiseni ukutshiza ngexesha lokufakwa kwesitshizi kunye nokuqinisekisa ukugqunywa okufanayo kwiiprofayili ezisezantsi ezineprofayile ezahlukeneyo zomhlaba.

Ifilimu yakudala:
I-HEC inegalelo ekwenzeni ifilimu eqhubekayo kunye neyunifomu kwi-substrate surface. Njengoko i-coating yomile, ii-molecule ze-HEC zilungelelanisa ukudala ifilimu edibeneyo, inikezela ukunamathela ngokugqwesileyo kwi-substrate kunye nokuphucula ukuqina kwengubo. Iipropathi zokwenza ifilim ze-HEC zibalulekile ekufezekiseni iimpawu ezinqwenelekayo zokugquma ezinje ngokuqina, ukuguquguquka, kunye nokumelana nemozulu. Ngaphezu koko, iifilimu ze-HEC zibonisa ukuxhathisa okulungileyo kwamanzi, zizenza zilungele iingubo ezivezwe kumanzi okanye kwiindawo zokufuma eziphezulu.

Impembelelo ye-HEC kuMsebenzi wokuTyala:

Ulawulo lweViscosity:
I-HEC yenza ukulawula okuchanekileyo kwi-viscosity yeengubo, ukuqinisekisa ukuhamba okuhamba phambili kunye neempawu zokulinganisa. Ulawulo olululo lwe-viscosity luthintela imiba enje ngokuntywila, ukuthontsiza, okanye ukugubungela ukungalingani ngexesha lesicelo, okukhokelela kumgangatho ophuculweyo wokugquma kunye nobuhle. Ngaphezu koko, indlela yokuziphatha yokucheba ye-HEC iququzelela isicelo esilula ngaphandle kokubeka esichengeni ukusebenza kokwambathisa.

Umgangatho kunye nokuchasana ne-Sag:
Iipropathi ze-rheological ezinikezelwe yi-HEC zinegalelo kumgangatho ogqwesileyo kunye nokumelana ne-sag yeengubo. Ngethuba lokusetyenziswa, i-HEC inciphisa ukuthambekela kokugquma ukwenza amanqaku e-brush okanye i-roller stipple, okubangela ukugqiba kunye nokufana okufanayo. Ukongeza, i-HEC iphucula indlela yokuziphatha yethixotropic yokugquma, inqanda ukuntywila okanye ukuthontsiza kwindawo ethe nkqo, ngaloo ndlela iphucula ukusebenza kakuhle kwesicelo kunye nokunciphisa inkunkuma yezinto.

Ukuncamathela:
I-HEC iphucula ukuncamathelwa kweengubo kwii-substrates ezahlukeneyo, kubandakanya isinyithi, iinkuni, iiplastiki kunye nekhonkrithi. Iimpawu zokwenza ifilimu ye-HEC zenza ibhondi eqinile phakathi kwengubo kunye ne-substrate, ukuphucula ukunamathela kwexesha elide kunye nokuqina. Oku kubaluleke kakhulu kwiingubo zangaphandle ezivezwe kwiimeko ezinzima zokusingqongileyo, apho ukunamathela kudlala indima ebalulekileyo ekuthinteleni ukusilela kokugquma okufana nokuxobula okanye ukubola.
