I-Latex Paint (eyaziwa nangokuthi upende osuselwa emanzini) uhlobo lopende olunamanzi njenge-solvent, elisetshenziselwa ukuhlobisa nokuvikelwa kwezindonga, uphahla nezinye izindawo eziphezulu. Ifomula ye-Latex Paint imvamisa iqukethe i-polymer emulsion, i-pigment, filler, izengezo nezinye izithako. Phakathi kwazo,I-Hydroxyyethyl cellulose (HEC)ungumkhulu obalulekile futhi usetshenziswa kabanzi ku-latex paint. I-HEC ayikwazi ukuthuthukisa ukuhlakanipha kanye ne-Rhelogy yopende, kepha futhi ithuthukisa ukusebenza kwefilimu yokupenda.
1. Izici eziyisisekelo ze-HEC
I-HEC iyinqwaba yamanzi ye-polymer iguqulwe kusuka ku-cellulose ngokuqina okuhle, ukumiswa kanye nezakhiwo ezenziwe ngefilimu. I-moleculat yayo inamaqembu e-hydroxyethyl, okuvumela ukuthi ichithe emanzini futhi yakha isixazululo esiphezulu. I-HEC ine-hydrophilicity eqinile, ekhombisa ukuthi idlale indima ekuqiniseni ukumiswa, ukulungisa i-Rhelogy kanye nokwenza ngcono ukusebenza kwefilimu ku-latex Paint.
2. Ukuxhumana phakathi kwe-hec ne-polymer emulsion
Ingxenye esemqoka ye-Latex Paint yi-polymer emulsion (njenge-acrylic acid noma i-ethylene-vinyl acetate copolymer emulsion), eyakha amathambo amakhulu wefilimu yokupenda. Ukuxhumana phakathi kweCicken®hec ne-polymer emulsion kubonakaliswa ikakhulukazi ezintweni ezilandelayo:
Ukuqina okuthuthukisiwe: I-HEC, njengomuntu omkhulu, ingakhulisa ukubonakala kopende we-latex nosizo Ikakhulu ema-emulsor e-polymer ephansi, ukungezwa kwe-HEC kunganciphisa ukunqunyelwa kwezinhlayiya ze-emulsion futhi kuthuthukise ukuqina kwesitoreji kopende.
Umthethonqubo we-Rheological: I-HEC ingaguqula izakhiwo zesimbozo sopende we-latex, ukuze isebenze kangcono ukuhlanganisa ndawonye ngesikhathi sokwakha. Isibonelo, ngesikhathi senqubo yokupenda, i-HEC ingathuthukisa impahla eshelelayo yopende futhi igweme ukudonsa noma ukugcwala kwe-coating. Ngaphezu kwalokho, i-HEC ingalawula futhi ukululama ngopende futhi kuthuthukise ukufana kwefilimu yokupenda.
Ukusebenziseka kahle kokusebenza kwe-coating: Ukungezwa kwe-HEC kungathuthukisa ukuguquguquka, ukuphefumula kanye nokumelana kweSkroma kwe-coating. Ukwakheka kwamangqamuzana kwe-HEC kungasebenzisana ne-polymer emulsion ukuthuthukisa ukwakheka okuphelele kwefilimu yokupenda, okwenza kube ngumncane futhi ngaleyo ndlela kuthuthukiswe ukuqina kwayo.
3. Ukuxhumana phakathi kwe-HEC kanye nemibala
Imibala e-Latex Paints ivame ukufaka imibala engaphansi (njenge-titanium dioxide, i-mica powder, njll.) Nemibala e-organic. Ukuxhumana phakathi kwe-HEC kanye nemibala kuboniswa ikakhulukazi ezintweni ezilandelayo:
Ukuhlakazeka kwe-Pigment: Umphumela wokuqina we-HEC ukhulisa ukubonakala kwe-latex Paint, engasabalalisa kangcono izinhlayiya ze-pigment futhi igweme ukuhlanganiswa noma ukuhanjiswa kwemvula. Ikakhulu izinhlayiya ezinhle ze-pigment, isakhiwo se-polymer sokwehla singasongelela ebusweni be-pigment ukuvikela i-agglomeration yezinhlayiya ze-pigment, ngaleyo ndlela yenza ngcono ukuhlakazwa kopende kanye nokufana kopende.
Amandla abopha phakathi kwefilimu ye-pigment kanye ne-coating:I-HECAma-molecule angakhiqiza ama-adsorption angokomzimba noma isenzo samakhemikhali ebusweni be-pigment, athuthukise amandla ahlanganisiwe phakathi kombala kanye nefilimu yokuhlanganisa, futhi agweme into yokuchithwa kwezingulube noma ukuncipha ebusweni befilimu ye-coatiment. Ikakhulu kupende we-latex asebenza kakhulu, i-HEC ingathuthukisa ngempumelelo ukumelana nesimo sezulu kanye nokumelana kwe-UV ye-pigment futhi yandise impilo yenkonzo ye-coating.
4. Ukuxhumana phakathi kwe-HEC ne-Filiers
Amanye ama-filler (anjenge-calcium carbonate, ama-talcum powder, amaminerali abubula, njll.) Ngokuvamile angezwe ku-Latex Paint ukuthuthukisa i-Rhex Paint ukuthuthukisa i-Rhex ngopende lopende, uthuthukise amandla okuhlakala kwepende. Ukuxhumana phakathi kwe-HEC kanye nama-filler kuboniswa kulezi zinto ezilandelayo:
Ukumiswa kwabaphangi: I-HEC ingagcina ama-filler angezwe ku-latex peint endaweni yokuhlakazeka efanayo yokusakazeka, ukuvimba ama-filler ukuthi axazulule. Okwama-filler anezinhlayiya ezinkulu ezinkulu, umphumela wokuqina we-HEC ubaluleke kakhulu, ongawugcina ngokuphumelelayo ukuqina kopende.
Isicwebezelisi kanye nokuthinta kwe-coating: Ukungezelelwa kwama-filler kuvame ukuthinta i-gloss kanye nokuthinta kwe-coating. ICINCENCHEL ®hec ingathuthukisa ukusebenza kokubukeka kwenhlanganisela ngokulungisa ukusatshalaliswa kanye nokuhlelwa kwama-filler. Isibonelo, ukuhlakazeka okufanayo kwezinhlayiya ze-filler kusiza ukunciphisa ubulukhuni bendawo yokuhlanganisa kanye nokuthuthukisa iflethi kanye nokucwengeka kwefilimu yokupenda.
5. Ukuxhumana phakathi kwe-HEC nezinye izengezo
Ifomula yopende we-latex ifaka nezinye izithasiselo, ezinjengezingcezwana, ama-proservative, ama-ejenti ama-weetting, njll. Lezi izengezo zingasebenzisana noHec ngenkathi zithuthukisa ukusebenza ngopende:
Ukuxhumana phakathi kwe-Defoamers ne-HEC: Umsebenzi wama-desoamers ukunciphisa ama-bubble noma igwebu ngopende, futhi izici eziphakeme ze-HEC zingathinta umphumela wama-desoamers. I-HEC eyeqile ingenza kube nzima nge-defoamer yokususa ngokuphelele igwebu, ngaleyo ndlela ithinta ikhwalithi ephezulu yopende. Ngakho-ke, inani le-HEC elengezwa lidinga ukuhlanganiswa nenani le-defoamer ukuze kufinyelelwe umphumela omuhle kakhulu.
Ukuxhumana phakathi kokugcina kanye ne-HEC: Indima yezindawo zokugcina ukuvikela ukukhula kwama-microorganisms kupende futhi kwandise isikhathi sokubhala ngopende. Njenge-polymer yemvelo, isakhiwo samangqamuzana e-HEC singaxhumana nezivikelo ezithile, okuthinta umphumela waso wokulwa nokuwohloka. Ngakho-ke, kubalulekile ukukhetha okulondoloziwe okuhambelana ne-HEC.
Indima yeI-HECKu-Latex Paint akukhona ukuqina kuphela, kepha ukusebenzisana kwayo nge-polymer emulsions, imibala, ama-filler nezinye izithako okuhlangene inquma ukusebenza kwe-latex Paint. ICINCCENCK®®CHHEC ingathuthukisa izakhiwo ze-rheological zopende we-latex, ithuthukise ukungafani kwemibala kanye nama-filler, futhi ithuthukise izakhiwo zemishini nokuqina kokuqina. Ngaphezu kwalokho, umphumela we-synergistic we-HEC nezinye izengezo futhi unomthelela obalulekile ekuqineni kwesitoreji, ekusebenzeni kokwakha kanye nokubukeka kombambo kwe-latex Paint. Ngakho-ke, ekwakhiweni kwefomula ye-Latex Paint formula, ukukhetha okuvumelekile kohlobo lwe-HEC kanye nenani lokungezelela kanye nokulinganisela kokuxhumana kwalo nezinye izithako kuyisihluthulelo sokwenza ngcono ukuthuthuka kwe-latex ngopende.
