Tos kom muaj kev hloov pauv tseem ceeb tab sis thim rov qab tshwm sim. Thaum siv cov tshuaj ntxiv, ntau daim ntawv ntau npaum nrog cov haujlwm tshiab tuaj yeem tsim los yog kev ua tau zoo ntawm cov ntaub ntawv thawj zaug tuaj yeem txhim kho.

● Cov khoom no ruaj khov nyob rau hauv ib txwm muaj thiab muaj zog kam rau ua kom sov, kua qaub thiab alkali.

Poly (N{0}}Vinyl Pyrrolidone)daim ntawv thov

Shenghui K series cov khoom siv tuaj yeem siv los ua binders rau granules thiab ntsiav tshuaj, thiab ua cov thickeners thiab tshem tawm cov neeg ua haujlwm rau kev npaj ua kua. Co- cov kuab tshuaj thiab stabilizers rau kev npaj, zaj duab xis- tsim cov neeg ua hauj lwm thiab cov xim dispersants rau coatings, coprecipitants rau cov tshuaj soluble tsis zoo, thiab sustained - tso tawm cov neeg sawv cev rau kev tswj- tso tawm cov ntawv ntau npaum, thiab lwm yam.
Kev ua haujlwm ntawm PVP hauv kev npaj yog ze ze rau nws qhov hnyav molecular, ntau npaum li cas, hnyav, tshuaj concentration, kub, ua tshuab, thiab lwm yam. Yog li ntawd, kom tau txais kev npaj zoo dua, koj yuav tsum xub paub txog lub cev thiab tshuaj lom neeg ntawm PVP, thiab pib los ntawm lub hom phiaj ua haujlwm kom tiav los ntawm cov tshuaj. , xaiv qhov zoo tshaj qhov hnyav molecular, ntau npaum li cas, hnyav, compatibility, thiab txheej txheem.

FAQ

Q: Dab tsi yog cov yam ntxwv tshwj xeeb thiab qhov zoo ntawm Poly (N-Vinyl Pyrrolidone) piv rau lwm cov polymers zoo sib xws?

A: Cov polyvidone peb muab tau zoo heev solubility. Nws tuaj yeem yaj sai sai thiab tag nrho hauv ntau cov kuab tshuaj, suav nrog cov dej thiab qee cov kuab tshuaj organic, uas ua rau nws hloov tau yooj yim hauv kev tsim cov tshuaj npaj. Tib lub sijhawm, nws muaj cov yeeb yaj kiab zoo - tsim cov khoom. Cov yeeb yaj kiab tsim yog tawv thiab muaj qee qhov kev hloov pauv, uas tuaj yeem tiv thaiv cov khoom xyaw nquag ntawm cov tshuaj thiab tswj nws qhov tso tawm. Tsis tas li ntawd, polyvidone muaj tshuaj lom neeg ruaj khov. Nyob rau hauv ib txwm cia thiab siv tej yam kev mob, nws muaj peev xwm tswj tau qhov ruaj khov ntawm nws cov qauv thiab kev ua tau zoo, thiab nws tsis yooj yim rau degradation los yog tshuaj lom neeg cov tshuaj tiv thaiv, yog li ua kom lub sij hawm ntev -kev cia siab ntawm qhov zoo thiab kev ua tau zoo ntawm cov tshuaj.

Q: Yog tias peb ntsib teeb meem hauv daim ntawv thov ntawm polyvidone hauv kev txhim kho kev npaj tshuaj tshiab, koj tuaj yeem muab kev txhawb nqa dab tsi?

A: Peb muaj pab pawg kws tshaj lij uas muaj kev paub dhau los thiab kev txawj ntse hauv kev siv polyvidone. Yog tias koj ntsib teeb meem thaum lub sijhawm tsim cov txheej txheem tsim, peb tuaj yeem muab cov lus qhia tsim qauv rau koj, thiab pab koj txiav txim siab qhov zoo tshaj plaws ntawm povidone, qhov hnyav molecular ntau yam, thiab kev sib raug zoo nrog lwm cov khoom ntxiv raws li koj cov tshuaj nquag siv thiab cov hom phiaj tsim. Peb tseem tuaj yeem muab cov kev taw qhia ua kom zoo rau cov txheej txheem tsis xws li povidone dissolution, ziab, thiab kev tsim cov yeeb yaj kiab, pab koj daws cov teeb meem uas yuav tshwm sim hauv cov txheej txheem tsim khoom tiag tiag, kom ntseeg tau tias koj txoj kev tsim kho tshuaj tuaj yeem txhawb nqa thiab thaum kawg ua tiav hauv kev ua lag luam.
