Anti-tsiaj thiab zaub roj zooNeoprene (CR) Npauj Npaim Valve Rooj
Neoprene (CR).
Neoprene, Polychloroprene yog tsim los ntawm chloroprene monomer polymerization. Tom qab vulcanization, nws muaj cov roj hmab zoo elasticity thiab abrasion tsis kam. Nws yog anti-insolation thiab muaj huab cua tsis zoo, tiv taus kev sib tsoo hnyav, tub yees, dilute acid, silicon ester lubricant, tab sis tsis tiv taus phosphate series ntawm hydraulic roj. Nws yog ib qho yooj yim rau crystallize thiab harden ntawm qhov kub thiab txias, tsis muaj zog cia stability, thiab loj expansion nyob rau hauv qis aniline point ntawm ntxhia roj. Hauv kev siv qhov kub thiab txias yog - 50 ~ 150 degree.
Qhov zoo:
Zoo elasticity thiab zoo compression deformation, cov mis tsis muaj leej faj, yog li nws yooj yim heev rau kev khiav lag luam. Nws muaj cov khoom tiv thaiv tsiaj thiab zaub roj, yuav tsis cuam tshuam los ntawm cov tshuaj nruab nrab, roj, roj, ntau yam roj, cov kuab tshuaj, thiab tseem muaj cov khoom tiv thaiv hluav taws.
Qhov tsis zoo:
Tsis pom zoo kom siv cov tshuaj muaj zog acids, nitrohydrocarbons, esters, chloroform thiab ketone tshuaj.
