I-HEC ye-Coatings

I-HEC (HYDROXYETHY celtuleose) iyinhlangano ye-anemic cellulose ether esetshenziswa kabanzi embonini yezambatho. Imisebenzi yayo ifaka phakathi ukuqina, ukusabalalisa, ukumisa nokuzinza, okungathuthukisa ukusebenza kokwakha kanye nomphumela owakhayo we-Coatings. I-HEC isetshenziswa kabanzi ekugqokeni okusekelwe emanzini ngoba ine-solubility enhle yamanzi nokuqina kwamakhemikhali.

1. Indlela yokusebenza kwe-HEC

Umphumela wokuqina

Eminye yemisebenzi esemqoka ye-HEC in Coatings iyaqina. Ngokwengeza i-viscosity yohlelo lokuhlanganisa, ukuhlanganisa izakhiwo ze-coating kanye nezindawo zokulinganisa zingathuthukiswa, into ebabazekayo ingancishiswa, futhi ukuhlanganiswa kungakha umfaniswano wokumboza odongeni noma kwezinye izindawo. Ngaphezu kwalokho, i-HEC inekhono eliqinile lokuqina, ngakho-ke lingafinyelela umphumela omuhle kakhulu ngisho nangokwengeza okuncane, futhi kunokusebenza kahle komnotho okuphezulu.

Ukumiswa kanye nokuzinza

Ohlelweni lwama-coating, izinhlayiya eziqinile ezifana nemibala kanye nezihlungi zidinga ukusatshalaliswa ngokulinganayo ezintweni eziyisisekelo, uma kungenjalo kuzothinta ukubukeka nokusebenza kwe-coating kanye nokusebenza kwenhlanganisela. I-HEC ingalondoloza ngempumelelo ukuhanjiswa okufanayo kwezinhlayiya eziqinile, kuvimbela ukuhanjiswa kwezulu, futhi kugcine ukuhlanganiswa kwezinsimbi ngesikhathi sesitoreji. Lokhu kumiswa komphumela kuvumela ukuhlanganiswa kabusha ukubuyela esimweni somfaniswano ngemuva kokugcina isikhathi eside, kunciphisa ukuhlukaniswa kanye nezulu.

Ukugcinwa kwamanzi

I-HEC ingasiza amanzi ngopende ukuthi akhishwe kancane ngesikhathi senqubo yokupenda, ngaleyo ndlela anwebise isikhathi sokomisa ngopende futhi asisekele ukuthi ikwaziswe ngokuphelele futhi kwakhiwe ngefilimu odongeni. Lokhu kusebenza kokugcinwa kwamanzi kubaluleke kakhulu emthethweni wokwakha, ikakhulukazi ezindaweni ezishisayo noma ezomile zokwakha, i-HEC inganciphisa kakhulu inkinga yokwakheka kwamafilimu okubangelwa ukuguquguquka kwamanzi okusheshayo.

Umthetho we-rheological

Izakhiwo ezimbongikazi zopende zithinta ngqo izizwa nekhwalithi yefilimu yokwakha. Isixazululo esakhiwe ngo-HEC ngemuva kokuncibilika emanzini sinamanzi ane-pseudoplasticity, okungukuthi, i-visa incipha ngaphansi kwamandla aphezulu we-shear (njengokuxubha nokuxubha), okulula ukuxubha; Kepha i-viscosity ilulama ngaphansi kwamandla aphansi we-shear, anganciphisa ukugcona. Lokhu akugcini kusiza ukwakhiwa, kepha futhi kuqinisekisa ukufana nobukhulu be-coating.

2. Izinzuzo ze-HEC

I-solubility yamanzi enhle

I-HEC iyinto ene-polymer engenawo amanzi. Isixazululo esakhiwe ngemuva kokuchithwa kucacile futhi kusobala, futhi akunamiphumela emibi ohlelweni lokupenda olususelwa emanzini. I-solubelity yayo futhi inquma kalula ukusetshenziswa kohlelo lokupenda, futhi ingancibilika ngokushesha ngaphandle kokukhiqiza izinhlayiya noma ama-agglomerates.

Ukuqina kwamakhemikhali

Njenge-Ether engekho-cellulose engekho, i-HEC inokuqina okuhle kwamakhemikhali futhi ayithinteka kalula yizinto ezinjenge-pH, lokushisa, kanye ne-ion yensimbi. Ingahlala iqinile ezindaweni ezinamandla ze-acid nase-alkaline, ngakho-ke ingazivumelanisa nezimo ezahlukahlukene zezinhlelo zokuhlanganisa.

Ukuvikelwa Kwezemvelo

Ngokwenza ngcono ukuqwashisa ngemvelo, okuphansi kwe-VOC (okuguquguqukayo kwe-Organic Compact Compact) kuya ngokuya kuthandwe. I-HEC ayinobuthi, ayinabungozi, ayinawo izixazululo ze-organic, futhi ihlangabezana nezidingo zokuvikelwa kwemvelo, ngakho-ke inezinhlobonhlobo zamathemba wohlelo lokusebenza ezitsheni ezisuselwa emvelweni zamanzi.

3. Umphumela we-HEC ezincelweni ezisebenzayo

I-Interior Wall Coatings

Emigqonyeni yodonga lwangaphakathi, i-HEC njengokuqina kanye nokushintshwa kwe-Rheology kungathuthukisa ukusebenza kokwakhiwa kwe-coating, kunikeze ukunciphisa izinga nokunamathelisa. Ngaphezu kwalokho, ngenxa yokugcinwa kwayo okuhle kakhulu kwamanzi, i-HEC ingavimba imifantu noma i-poffaling ye-Interior Wall Coatings ngesikhathi senqubo yomiswa.

Imidwebo yodonga lwangaphandle

Imidwebo yodonga lwangaphandle idinga ukuba nokumelana kwesimo sezulu okuhle nokumelana kwamanzi. I-HEC ayikwazi ukuthuthukisa ukugcinwa kwamanzi kanye ne-Rheology of the coating, kepha futhi ithuthukisa impahla elwa nama-coating coating, ukuze ama-coating angamelana kangcono nomoya nemvula ngemuva kokwakha futhi anwebe impilo yayo yenkonzo.

I-Latex Paint

Ku-Latex Paint, i-HEC ayikwazi ukwenza kuphela njengomuntu omkhulu, kepha futhi ithuthukisa ubuwula bopende futhi yenza ifilimu yokuhlanganisa i-coating. Ngasikhathi sinye, i-HEC ingavimbela imvula yemibala, ithuthukise ukuqina kwesitoreji sopende, futhi yenza upende we-latex uzwenze ngemuva kokugcinwa isikhathi eside.

IV. Izindlela zokuqapha zokungeza nokusebenzisa i-HEC

Indlela yokuchithwa

I-HEC ivame ukungezwa kupende ngefomu le-powder. Lapho usebenzisa, kudinga ukufakwa kancane kancane emanzini futhi kuvuselele ngokuphelele ukuqeda ngokulinganayo. Uma ukuhlukaniswa kunganele, kungavela izinto ze-granular, zithinta ikhwalithi yokubukeka ngopende.

Ukulawulwa kwemithamo

Inani le-HEC lidinga ukulungiswa ngokuya ngefomula yopende kanye nomphumela odingekayo wokuqina. Inani lesengezo elijwayelekile lingu-0.3% -1.0% wenani eliphelele. Kungenzeka ukuthi ukwengeza kuzodala ukuthi ukubonwa kopende kube phezulu kakhulu, okuthinta ukusebenza kokwakha; Isengezo esanele sizodala izinkinga ezinjengamandla asongelayo futhi anganele.

Ukuhambisana nezinye izithako

Lapho usebenzisa i-HEC, naka ukuhambisana nezinye izithako zopende, ikakhulukazi imibala, ama-filler, njll. Kuzinhlelo ezihlukile zokupenda, uhlobo noma inani le-HEC lingadinga ukulungiswa ukuze kugwenywe ukugwema ukuphendula okunzima.

I-HEC idlala indima ebalulekile embonini yezenhlaya, ikakhulukazi egqoke izigqoko ezisuselwa emanzini. Kungathuthukisa ukuwenza, izakhiwo ezakha amafilimu kanye nokuqina kokugcina kwezingubo zokugqoka, futhi kunozinzwa okuhle kwamakhemikhali nokuvikelwa kwemvelo. Njengomkhulu osebenza ngempumelelo kanye ne-Rheology Modifier, i-HEC isetshenziswa kabanzi emboni ye-Interior Wall, imidwebo yodonga lwangaphandle kanye nopende we-latex. Kuzinhlelo zokusebenza ezisebenzayo, ngokulawulwa komthamo ofanele kanye nezindlela ezifanele zokuqothula, i-HEC inganikeza ngemiphumela ekahle yokuqina kanye nokuzinza kwezimali zokuqamba futhi ithuthukise ukusebenza kwezembatho.
