I-HPMC YB 510M

I-EipponCell HPMC YB510M iyi-medium viscosity cellulose ether.Inqubo yokukhiqizwa kwe-cellulose ether ibandakanya ukusetshenziswa kwe-pulp kakotini ecolisisiwe/ukotini/i-pulp yokhuni njengento yokuqala esetshenziswayo, eyenziwe nge-alkaline ukuze kutholwe i-cellulose.Kamuva, i-propylene oxide ne-methyl chloride yengezwe ukuze i-etherification, okuholele ekwakhekeni kwe-cellulose ether.Eyaziwa ngokuthi “i-industrial monosodium glutamate,” i-cellulose ether inezakhiwo ezihlukile, okuhlanganisa ukujiya kwesixazululo, ukuncibilika kwamanzi okuhle kakhulu, ukumiswa noma ukuzinza kwe-latex, amandla okwenza ifilimu, ukugcinwa kwamanzi, nokunamathela.

Endabeni ye-EipponCell HPMC YB510M, isebenza ngokukhethekile njenge-hydroxypropyl methyl cellulose esetshenziswa kumapende asekelwe emanzini nasezikhiqizweni zopende.Le ether cellulose inikeza izinzuzo ezibalulekile kulezi zinhlelo zokusebenza.Isiza ekuqiniseni ikhambi lopende, liqinisekise ukuvumelana okufanele kanye nokuhlanganisa okuthuthukisiwe phakathi nokufakwa.Ngaphezu kwalokho, ikhombisa ukuncibilika kwamanzi okuhle, okuvumela ukuxutshwa kalula nokulungiswa kwamapende asekelwe emanzini.I-Cellulose ether iphinde isize ekuzinzeni kokumiswa, ukuvimbela ama-pigments ukuthi angahlali futhi aqinisekise ukusabalalisa okufanayo kuwo wonke upende.Futhi, isiza ekwakhekeni kwefilimu ehlala isikhathi eside endaweni ependiwe, ithuthukise impilo ende nokuvikelwa kopende.

Ngaphezu kwalokho, i-EipponCell HPMC YB510M ibonisa ukugcinwa kwamanzi okuhle kakhulu, igcina ikhambi lopende lisesimweni esisebenzisekayo isikhathi eside, kunciphisa ingcuphe yokomisa noma ukusulwa kwesikhumba.Iphinde inikeze izakhiwo zokunamathela, ezikhuthaza ukubopha okuqinile phakathi kwendawo ependiwe kanye nefilimu kapende, okuholela ekuqiniseni ukuqina okuthuthukisiwe kanye nokumelana nokuxebuka noma ukucwayiza.

Ukusetshenziswa kwe-HPMC YB 510M

I-EipponCell HPMC YB 510M ingasetshenziswa kupende osuselwe emanzini nasekususeni upende.Izisusi zopende ziyizinto, kungaba izincibilikisi noma ama-paste, eziklanyelwe ukuncibilikisa noma ukuvuvukalisa amafilimu okunameka.Ahlanganisa ikakhulukazi izincibilikisi ezinamandla, upharafini, i-cellulose ether, phakathi kwezinye izithako.

Ekwakhiweni kwemikhumbi, izindlela ezehlukene zemishini ezifana nokufosholo ngesandla, ukuqhunyiswa kwesibhamu, ukuqhunyiswa kwesihlabathi, amanzi anomfutho omkhulu, namajethi abrasive ngokuvamile asetshenziswa ukuze kususwe izimbotshana ezindala.Kodwa-ke, lapho usebenzisana nezimbotshana ze-aluminium, lezi zindlela zomshini zingase ziklwebhe indawo engaphezulu ye-aluminium.Ngenxa yalokho, ukupholisha nge-sandpaper kanye nokukhipha upende kuvame ukusetshenziswa njengendlela eyinhloko yokukhipha ifilimu kapende endala.

Izinzuzo zokusebenzisa isikhiphi sikapende zifaka ukusebenza kahle okuphezulu, ukusetshenziswa kwezinga lokushisa kwegumbi, ukugqwala okuncane ezinsimbi, ukufaka isicelo esilula, futhi asikho isidingo semishini eyengeziwe. Nokho, kubalulekile ukuqaphela ukuthi ezinye izinto ezikhipha upende zingaba yingozi, ziguquguquke, zivuthe futhi zibiza. . Ukuthuthukiswa kwemikhiqizo emisha yokukhipha upende, okuhlanganisa nezinye izinto ezisekelwe emanzini, bekulokhu kukhuphuka eminyakeni yamuva. Le ntuthuko iholele ekuthuthukiseni ukusebenza kahle kokususa upende kanye nokusebenza okuthuthukisiwe kwemvelo. imikhiqizo evuthayo iye yanda kancane kancane emakethe yokukhipha upende.

Isimiso sokukhumula upende

Indlela eyinhloko yokukhipha upende incike ekusetshenzisweni kwezincibilikisi zemvelo ukuze kuncibilike futhi kugcwale izinhlobo ezahlukene zamafilimu okunameka, ngaleyo ndlela kube lula ukukhishwa kwezingqimba zopende ezindala endaweni engaphansi.Lapho isikhiphi sikapende singena ezikhaleni phakathi kwamaketanga e-polymer ngaphakathi kwengubo, iqala ukuvuvukala kwe-polymer.Ngenxa yalokho, umthamo wefilimu eboshiwe uyakhula, okuholela ekunciphiseni ukucindezeleka kwangaphakathi okukhiqizwa i-polymer ekhulayo.Ekugcineni, lokhu kuncipha kokucindezeleka kwangaphakathi kuphazamisa ukunamathela phakathi kwefilimu eboshwe kanye ne-substrate.

Njengoba isikhiphi sikapende siqhubeka sisebenza efilimini eboshiwe, siqhubeka sisuka ekuvuvukeni kwendawo siye ekuvuvukeni kweshidi elibanzi.Lokhu kuphumela ekwakhekeni kwemibimbi ngaphakathi kwefilimu eboshiwe futhi ekugcineni kulimaze ngokuphelele ukunamathela kwayo ku-substrate. Ekugcineni, ulwelwesi olumboziwe luba sengozini kuze kube seqophelweni lapho lungasuswa khona ngokuphumelelayo.

Ngale nqubo, i-solvent ye-organic ekukhipheni upende iphula ngokuphumelelayo izibopho zamakhemikhali ngaphakathi kwefilimu yokuhlanganisa, yenza buthaka ubuqotho bayo besakhiwo futhi idale izimo zokususwa kwayo. ukupendiwa kabusha noma ezinye izinhlelo zokusebenza.

Ukuhlukaniswa kwesikhiphi sikapende

Ama-stripper kapende angahlukaniswa abe yizinhlobo ezimbili eziyinhloko ngokusekelwe ohlotsheni lwezinto zokwakha ifilimu abazisusayo.Uhlobo lokuqala lusebenzisa izincibilikisi eziphilayo njengama-ketone, i-benzenes, nopharafini we-volatilization retarder (okwaziwa ngokujwayelekile ngokuthi i-lotion emhlophe).Lezi zisusa zopende zisetshenziselwa ngokuyinhloko ukususa amafilimu amadala opende enziwe ngamapende asuselwa kuwoyela, asuselwa ku-alkyd, noma asuselwa ku-nitro.Ivamise ukwakhiwa ngezincibilikisi eziphilayo eziguquguqukayo, ezingabonisa ukuvutha kanye nezinkinga zobuthi.Nokho, zibiza kancane.

Uhlobo lwesibili lokususa upende luyi-chlorinated hydrocarbon formulation, equkethe ngokuyinhloko i-dichloromethane, ipharafini, ne-cellulose ether.Lolu hlobo luvame ukubizwa ngokuthi isikhiphi sikapende esishaywayo. Ngokuyinhloko sisetshenziselwa ukususa izambatho ezindala eziphulukisiwe ezifana ne-epoxy asphalt, i-polyurethane, i-epoxy polyethylene, noma ama-amino alkyd resins. Lolu hlobo lwesikhiphi sikapende lunikeza ukusebenza kahle kokususa upende, ubuthi obuphansi, kanye nohlu olubanzi lwezinhlelo zokusebenza.

Izikhiqizo zikapende eziqukethe i-dichloromethane njengesinyibilikisi esiyinhloko zingaphinda zihlukaniswe ngokusekelwe kumanani e-pH. Sihlukaniswe ngezisusa zopende ezingathathi hlangothi ezinenani le-pH elicishe libe ngu-7±1, izinto ezikhipha upende ezine-alkali ezinenani le-pH elingaphezu kuka-7, nezikhiphi zopende ezine-asidi. enenani eliphansi le-pH.

Lezi zinhlobo ezihlukene zokususa upende zinikeza izinketho zokususa ngempumelelo izinhlobo ezithile zamafilimu opende, ezinikeza amazinga ahlukahlukene obuthi, ukusebenza kahle, nokufaneleka kokusebenza. Kubalulekile ukukhetha isikhiphi sikapende esifanele ngokusekelwe embotsheni ethile okufanele ikhishwe kanye izidingo ezifiselekayo zokuphepha nokusebenza.
