Dipropylene glycol diacrylate muaj ntau yam kev siv hauv kev yees duab
Lub cev muaj zog: DPGDA yog cov xim tsis muaj xim rau cov kua daj daj uas tsis muaj viscosity thiab volatility. Nws qhov ceev yog kwv yees li 1.07 g / cm³, qhov kub ntawm qhov kub yog li 225 ° C thiab lub teeb nyem yog li 120 ° C. DPGDA yog soluble hauv ntau cov organic solvents, xws li cawv, ketones, ethers, thiab lwm yam.
Cov yam ntxwv ntawm cov qauv: Cov qauv molecular ntawm DPGDA yog tsim los ntawm ob pawg acrylic ester txuas nrog cov molecule ntawm propylene glycol. Cov qauv no tso cai rau DPGDA nrog kev ua haujlwm zoo thiab muaj peev xwm sib txuas.
Reactivity: DPGDA yog ib qho kev sib xyaw nrog kev ua haujlwm siab. Nws tuaj yeem dhau los ua cov tshuaj dawb radical polymerization nyob rau hauv qhov kev txiav txim ntawm ultraviolet lub teeb, hluav taws xob hluav taws xob, lossis thermal pib tsim cov polymer. Vim nws ob pawg acrylic ester, DPGDA tuaj yeem qhia crosslinking cov ntsiab lus hauv cov tshuaj tiv thaiv polymerization, nce qib ntawm crosslinking thiab mechanical zog ntawm cov polymer.
Daim ntawv thov teb: DPGDA muaj ntau yam kev siv hauv kev yees duab. Nws yog dav siv nyob rau hauv teb xws li UV kho coatings, photosensitive adhesives, inks, coatings, thiab adhesives. Lub siab reactivity ntawm DPGDA ua rau nws yog ib qho zoo tagnrho crosslinking tus neeg saib xyuas thiab reactive diluent, uas tuaj yeem kho cov viscosity thiab kho tus nqi ntawm cov tshuaj tiv thaiv polymer.
Cov yam ntxwv thiab qhov zoo: DPGDA muaj cov yam ntxwv thiab qhov zoo, xws li qis viscosity, zoo polymerization kev ua tau zoo, muaj peev xwm hla kev sib txuas, thiab tshuaj lom neeg ruaj khov. Nws tuaj yeem raug copolymerization cov tshuaj tiv thaiv nrog lwm cov monomers thiab polymers. Tsis tas li ntawd, tus ntoo khaub lig-txuas polymer ntawm DPGDA nthuav tawm cov hluav taws kub zoo, tshuaj lom neeg, thiab cov khoom siv kho tshuab.
Kev ruaj ntseg: Thaum siv DPGDA, nws yuav tsum ua raws li cov txheej txheem kev nyab xeeb. Cov cuab yeej tiv thaiv tus kheej tsim nyog, xws li hnab looj tes thiab tsom iav, yuav tsum hnav kom tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
