Product Description:

Vinylpyrrolidone-Copolymer (NVP) yog ib qho organic compound uas muaj ib tug 5-membered lactam txuas mus rau ib pawg vinyl. Nws yog cov kua tsis muaj xim txawm tias cov qauv coj mus muag tuaj yeem tshwm daj. Nws yog tsim industrially los ntawm vinylation ntawm 2-pyrrolidone, piv txwv li lub hauv paus-catalyzed cov tshuaj tiv thaiv nrog acetylene.

Chemical Structure:

Txoj kev khaws cia:

Cov khoom no yuav tsum tau muab ntim rau hauv qhov chaw txias, qhuav thiab tiv thaiv los ntawm lub teeb.

Kev xav txog kev ua haujlwm:

Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Tsis txhob ua pa vapor thiab huab cua.

Kev ceev faj cia:

Khaws rau hauv qhov chaw txias. Khaws lub thawv kaw kom nruj thiab khaws cia rau hauv qhov chaw qhuav thiab qhov cua. Cov thawv uas tau qhib lawm yuav tsum tau ua tib zoo rov muab dua thiab khaws cia kom ruaj khov kom tsis txhob xau.

Kev daws teeb meem:

Ua los ntawm kev ua ntawm 2-pyrrolidone thiab acetylene nyob rau hauv siab

Daim ntawv thov:

1. Nyob rau hauv cov yas, Cov monomer no tuaj yeem muab ntxiv rau hauv cov txheej txheem ntawm UV curing coatings los ua ib zaj duab xis hloov tau yooj yim thiab tawv. Ntxiv NVP rau cov tshuaj tiv thaiv hluav taws xob tuaj yeem txhim kho qhov elongation thiab viscosity ntawm high-gloss thiab low-gloss txheej.

2. Nyob rau hauv Ntoo, txhim kho cov khoom ua tau zoo, txhim kho cov khoom tsim tau, thiab txo qhov siab ntawm ib puag ncig cov pa phem. Cov no yog cov laj thawj tseem ceeb uas yog vim li cas kev siv cov txheej txheej hauv cov rooj tog zaum yuav tsum tau tshawb xyuas. Qhov sib ntxiv ntawm NVP rau cov tshuaj tiv thaiv ultraviolet siv hauv kev lag luam ntoo hauv pem teb tuaj yeem muab qhov sib npaug ntawm lub cev ntawm cov khoom siv tsis muaj quav nyab.
