Khoom Taw Qhia Thiab Daim Ntawv Thov
Nyob rau hauv chav tsev kub yog ib tug tsis muaj kob los yog lub teeb daj pob tshab kua nrog ib tug me ntsis tsw. Nws yog yooj yim soluble nyob rau hauv dej thiab lwm yam organic solvents. Nws yog active nyob rau hauv chemical zog thiab yooj yim rau hydrolyze thiab polymerize. N-vinylpyrrolidone kuj yog cov organic hnyav nrog kev ua tau zoo heev. Explosion txwv expl. lim. 10%, rhiab rau lub teeb.
Daim ntawv thov:
1. Yas no monomer tuaj yeem muab ntxiv rau hauv cov qauv ntawm UV curing txheej los ua ib zaj duab xis hloov tau thiab tawv. Ntxiv NVP rau cov qauv kev kho mob hluav taws xob tuaj yeem txhim kho tus nqi elongation thiab viscosity ntawm cov teeb pom kev siab thiab lub teeb qis.
2. Ntoo txhim kho cov khoom ua tau zoo, txhim kho kev tsim khoom thiab txo cov kev ntxhov siab ntawm ib puag ncig cov pa phem, uas yog lub ntsiab lus txhawb siab rau kev siv cov txheej txheej hauv cov rooj tog zaum. Qhov sib ntxiv ntawm NVP rau cov txheej txheem tiv thaiv ultraviolet siv hauv kev lag luam ntoo hauv pem teb tuaj yeem muab cov khoom siv lub cev ntawm cov ntaub pua tsev tsis muaj wax.
3. UB thiab EB curing coatings siv nyob rau hauv papermaking los yog paperboard feem ntau yuav tsum tau qis viscosity thiab siab reactivity. NVP ua tau raws li cov qauv no los ntawm kev txhim kho fluidity thiab ntsuas qib, thiab tswj cov yam ntxwv kho kom zoo
