Kwishishini leengubo zanamhlanje, ukusebenza kokusingqongileyo kube yenye yezalathisi ezibalulekileyo zokulinganisa umgangatho wokugquma.Iselulosi yeHydroxyethyl (HEC), njenge-polymer thickener e-soluble yamanzi eqhelekileyo kunye ne-stabilizer, isetyenziswa ngokubanzi kwiingubo zezakhiwo, iipeyinti ze-latex kunye neengubo ezisekelwe emanzini. I-HEC ayiphuculi kuphela ukusebenza kwesicelo seengubo, kodwa inefuthe elinzulu kwiipropati zabo zokusingqongileyo.
1. Umthombo kunye neempawu ze-HEC
I-HEC yi-polymer compound efunyenwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo, enokubola kunye ne-non-toxic. Njengomathiriyeli wendalo, inkqubo yokuvelisa kunye nokusetyenziswa kwayo kunempembelelo ephantsi kakhulu kwindalo esingqongileyo. I-HEC inokuzinzisa i-dispersions, ilungelelanise i-viscosity kunye nokulawula i-rheology kwiinkqubo zokugubungela, ngelixa ugwema ukusetyenziswa kwezongezo zekhemikhali eziyingozi kwindalo. Ezi mpawu zibeka isiseko se-HEC ukuba ibe yinto ephambili ekuqulunqweni kokwaleka kokusingqongileyo.
2. Ukuphuculwa kwezithako zokugquma
I-HEC inciphisa ukuxhomekeka kwizithako ezingcolisa kakhulu ngokuphucula ukusebenza kokwambathisa. Ngokomzekelo, kwiingubo ezisekelwe emanzini, i-HEC inokuphucula i-dispersibility of pigments, ukunciphisa imfuno ye-solvent-based dispersants, kunye nokunciphisa ukukhutshwa kwezinto ezinobungozi. Ukongezelela, i-HEC ine-solubility efanelekileyo yamanzi kunye nokunyanzeliswa kwetyuwa, enokunceda i-coating igcine ukusebenza okuzinzile kwiindawo eziphakamileyo zomswakama, okunciphisa ukungaphumeleli kunye nokuchithwa kweengubo ezibangelwa yimiba yokusingqongileyo, ngaloo ndlela ixhasa ngokungathanga ngqo iinjongo zokukhusela indalo.
3. Ulawulo lwe-VOC
I-Volatile organic compounds (VOC) yenye yemithombo ephambili yongcoliseko kwiingubo zemveli kwaye ibeka isongelo esinokubakho kwindalo kunye nempilo yabantu. Njenge-thickener, i-HEC inokunyibilika ngokupheleleyo emanzini kwaye ihambelana kakhulu neenkqubo zokugquma kwamanzi, ukunciphisa ngokufanelekileyo ukuxhomekeka kwi-solvents yezinto eziphilayo kunye nokunciphisa ukukhutshwa kwe-VOC kumthombo. Xa kuthelekiswa ne-thickeners yendabuko efana ne-silicones okanye i-acrylics, ukusetyenziswa kwe-HEC kuhambelana nokusingqongileyo ngelixa kugcinwa ukusebenza kweengubo.
4. Ukukhuthazwa kophuhliso oluzinzileyo
Ukusetyenziswa kwe-HEC akubonakalisi nje ukukhuthaza izinto ezihambelana nokusingqongileyo, kodwa kukhuthaza uphuhliso oluzinzileyo lweshishini lokugquma. Ngakolunye uhlangothi, njengento ekhutshwe kwimithombo ehlaziyiweyo, imveliso ye-HEC ixhomekeke ngaphantsi kumafutha e-fossil; ngakolunye uhlangothi, ukusebenza kakuhle okuphezulu kwe-HEC kwiingubo kwandisa ubomi benkonzo yemveliso, ngaloo ndlela kunciphisa ukusetyenziswa kwezixhobo kunye nokuveliswa kwenkunkuma. Ngokomzekelo, kwiipeyinti zokuhombisa, iifomyula kunye ne-HEC zinokuphucula ukuxhathisa ukukhuhla kunye neempawu ezichasayo zepeyinti, okwenza iimveliso ezisetyenziswa ngabathengi ziqine ngakumbi, ngaloo ndlela zinciphisa ukuphindaphinda kokwakhiwa okuphindaphindiweyo kunye nomthwalo wokusingqongileyo.
5. Imingeni yobuGcisa kunye noPhuhliso lwexesha elizayo
Nangona i-HEC ineenzuzo ezibalulekileyo ekusebenzeni kokusingqongileyo kweepeyinti, ukusetyenziswa kwayo kukwajongene nemingeni ethile yobugcisa. Ngokomzekelo, izinga lokuchithwa kunye nokuzinza kwe-chear ye-HEC kunokulinganiselwa kwiifomyula ezithile, kwaye ukusebenza kwayo kufuneka kuphuculwe ngokuphucula ngakumbi inkqubo. Ukongeza, ngokuqiniswa okuqhubekayo kwemimiselo yokusingqongileyo, imfuno yezithako ezisekelwe kwi-bio-based kwiipende nazo ziyanda. Indlela yokudibanisa i-HEC kunye nezinye izinto eziluhlaza lukhokelo lophando lwexesha elizayo. Ngokomzekelo, ukuphuhliswa kwenkqubo edibeneyo ye-HEC kunye nama-nanomaterials ayinakukwazi ukuphucula ngakumbi iimpawu zemishini yepeyinti, kodwa iphinde ikhulise amandla ayo okulwa ne-antibacterial kunye ne-anti-fouling ukuhlangabezana neemfuno eziphezulu zokusingqongileyo.
Njengesixhobo sokutyebisa esinobuhlobo nokusingqongileyo esivela kwiselulosi yendalo,I-HECiphucula kakhulu ukusebenza kokusingqongileyo kweepeyinti. Ibonelela ngenkxaso ebalulekileyo yotshintsho oluluhlaza kushishino lwepeyinti lwangoku ngokunciphisa ukukhutshwa kwe-VOC, ukulungelelanisa imizobo yepeyinti, kunye nokuxhasa uphuhliso oluzinzileyo. Nangona ezinye iinzima zobugcisa kusafuneka zoyiswe, amathuba okusebenza okubanzi kwe-HEC kwiipeyinti ezihambelana nokusingqongileyo ngokuqinisekileyo alungile kwaye agcwele amandla. Ngokuchasene nemvelaphi yokwandisa ulwazi lokusingqongileyo kwihlabathi, i-HEC iya kuqhubeka iphakamisa amandla ayo okuqhuba ishishini lezogquma ukuya kwikamva eliluhlaza nelizinzileyo.
