VP/VA Copolymers
*Izimonyo zeBanga le-VP/VA Copolymers ngezabelo ezahlukene ze-N-Vinylpyrrolidone kuya kuVinyl Acetate, ezincibilika kuzincibilikisi eziningi eziphilayo.Etholakala kuyimpushana, isixazululo samanzi kanye nefomu lesisombululo se-ethnol. Izixazululo ezinamanzi ze-VP/VA Copolymers aziyona i-ionic, ukungathathi hlangothi akudingeki, Amafilimu anemiphumela aqinile, acwebezelayo, futhi awakhipheli amanzi; I-viscosity ye-tunable, indawo yokuthambisa kanye nokuzwela kwamanzi kuye ngesilinganiso se-VP/VA; Ukuhambisana okuhle nama-modifiers amaningi, ama-plasticizers, ama-propellant of spray nezinye izithako zezimonyo, kanye ne-hydroscopicity iyehla ngokulingana nesilinganiso se-Vinyl acetate.

Izicelo:
I-VP/VA Copolymers iyisinqumo esihle kakhulu njenge-ejenti yokwakha ifilimu kanye ne-ejenti yokwenza izinwele, elungele ukwenziwa kwefilimu kanye nokuguqulwa kwe-viscosity, ikakhulukazi emikhiqizweni yokwenza izinwele, njenge-Hair Gels, izifutho zegesi ye-Aerosol, izifutho zokubukeka ezimanzi. .
**********************************************
*Ibanga Lezemithi VP/VA Copolymer-I-Copovidonenge-60/40 isilinganiso se-N-Vinylpyrrolidone kuya ku-Vinyl Acetate, encibilika kuzincibilikisi eziningi eziphilayo.I-Copovidone yakha amafilimu aqinile, akhiphekayo emanzini nacwebezelayo, inokuhambisana okuhle kakhulu nama-plasticizer amaningi nama-modifiers. Ukuncibilika okuhle emanzini, otshwaleni nakwezinye izincibilikisi eziphilayo.
Amapharamitha Abalulekile Wezobuchwepheshe:
| Ukubukeka | Impushana emhlophe noma ephuzi-mhlophe noma ama-flakes, i-hygroscopic |
| I-Viscosity(Express as K Value) | 25.20~30.24 |
| Ukuncibilika | Incibilika ngokukhululekile emanzini, otshwaleni naku-methylene chloride |
| Izimpawu | A.I-Infrared Absorption |
| Kuvela umbala obomvu ongu-BA | |
| Umbala we-CA violet uyavela | |
| Ama-Peroxides (avezwe njengo-H2O2) | 400 ppm ubukhulu. |
| IHydrazine | 1 ppm ubuningi. |
| Ama-Monomers(VP+VA) | 0.1% ubuningi. |
| Ukungcola A(2-Pyrrolidone) | 0.5% ubuningi. |
| Izinsimbi Ezisindayo (njenge-Pb) | 20 ppm ubuningi. |
| Ukulahlekelwa Ekumisweni | 5.0% ubuningi. |
| Umlotha one-sulphate | 0.1% ubuningi. |
| Okuqukethwe kwe-Ethenyl Acetate | 35.3 ~ 42.0% ubuningi. |
| Okuqukethwe kwe-nitrogen | 7.0~8.0% |
Izicelo:
I-Copovidone isetshenziswa kakhulu njengesibophezelo esincibilika emanzini kanye ne-binder eyomile ezinqubweni ze-granulation ezimanzi / eziqondile, futhi ingasetshenziswa njengezinto zokwakha ifilimu.
*I-binder yethebhulethi encibilika emanzini, ilungele izinqubo zokucindezelwa okumanzi noma ezomile/zokuminyanisa okuqondile.
*Ifilimu Yangaphambili: ifilimu evumela ukuthi ifakwe i-tablet ne-sugar coatings ukuze ivikeleke ekuhlukaneni, ukunciphisa ukuzwela komswakama futhi inikeze ukunamathela okuhle kwefilimu.

*I-Technical Grade VP/VA Copolymersanezilinganiso ezahlukene ze-vinylpyrrolidone kuya ku-vinyl acetate futhi itholakala njengempushana emhlophe noma izixazululo ezisobala emanzini, i-thanol ne-isopropanol. Yakha amafilimu aqinile, acwebezelayo, aguquguqukayo, akhiphekayo, angenawo umoya-mpilo anamathela engilazini, amapulasitiki nezinsimbi, lezi. izakhiwo, kuhlanganiswe nekhono lokulawula i-hydrophilicity yazo ngokwakhiwa kwe-monomer, kuholela ekusetshenzisweni okubanzi kwezimboni.
