Anti-tsiaj thiab zaub roj zooNeoprene (CR) Npauj Npaim Valve Rooj
Neoprene (cr)
Neoprene, polychloroprene yog muaj los ntawm chloroprene monomer polymerization. Tom qab vulcanization, nws muaj cov roj hmab zoo elasticity thiab puas tsis resistance. Nws yog anti -insolation Thiab muaj huab cua zoo tsis kam, tiv taus kev ua phem rau distortion, dilute acid, silicon estreer roj, tab sis tsis txhob tawm hauv phosphate series ntawm cov roj. Nws yog ib qho yooj yim rau crystallize thiab harden ntawm tsawg kub, qhov chaw khaws khoom tsis muaj zog, thiab nthuav dav loj hauv cov roj ntxhia. Hauv kev siv kub ntau yog - 50 ~ 150 Qib.
Qhov zoo:
Zoo elasticity thiab kev ua tau zoo ua kom muaj kev deformation, cov mis tsis muaj leej twg, yog li nws yooj yim heev rau kev khiav lag luam. Nws muaj anti - tsiaj thiab zaub roj cov khoom, yuav tsis muaj cuam tshuam los ntawm cov tshuaj nruab nrab, cov roj, roj, thiab kuj muaj anti - hluav taws.
Qhov tsis zoo:
Tsis txhob pom zoo kom siv nyob rau hauv muaj zog acids, nitrohydrrocarbons, esters, chloroform thiab Ketone tshuaj lom neeg.
Daim ntawv thov:
Roj hmab qhov chaw lossis cov khoom ntim nrog R12 cov khoom siv hauv tsev. Haum rau cov roj hmab khoom uas ncaj qha rau kev sib cuag nrog cov huab cua, tshav ntuj, ozone seem, tiv thaiv hluav taws thiab tshuaj corrosion.
