Lapa Kloroprene(CR)

ʻO Chloroprene Rubber kahi ʻōpala synthetic i hana ʻia e ka α-polymerization o chloroprene (ie 2-chloro-1,3-butadiene) ma ke ʻano he kumu kumu. Hoʻohana nui ʻia ia i nā huahana anti-weathering, viscose soles, a me nā uhi. a me ka wahie rocket.

ʻIke ʻia e like me ke keʻokeʻo keʻokeʻo, ka beige a i ʻole ka ʻulaʻula ʻulaʻula a i ʻole nā ​​poloka, ʻo Neoprene he elastomer & koʻikoʻi o nā ʻano like ʻole o ka rubber synthetic. ʻO ka hemahema, ʻo ke kū anuanu maikaʻi ʻole a me ke kūpaʻa mālama.

Loaʻa i ka Neoprene ka ikaika tensile kiʻekiʻe, elongation, reversible crystallinity a me ka adhesion maikaʻi. Kū'ē i kaʻelemakule a me ka wela. ʻO ka ʻaila maikaʻi a me ka pale kemika. ʻO ka pale ʻana i ka wā a me ka pale ʻana o ka ozone ka lua wale nō i ka ethylene propylene rubber a me ka butyl rubber. ʻO ke kūpaʻa wela e like me ka nitrile rubber, me ka mahana decomposition o 230 a 260 ° C, kū'ē pōkole i 120 a 150 ° C, a me ka hoʻohana lōʻihi ma 80 a 100 ° C. Loaʻa iā ia ka hoʻopaʻa ahi. ʻO ka pale ʻaila ka lua ma mua o ka nitrile rubber. Kūleʻa maikaʻi i ka waika inorganic a me ka corrosion alkali.

ʻO ka palena hoʻoheheʻe o ka chloroprene rubber account no δ=9.2~9.41. Hiki ke hoʻoheheʻe ʻia i loko o toluene, xylene, dichloroethane, trivanadium, hiki ke hoʻoheheʻe ʻia i ka acetone, methyl ethyl ketone, ethyl acetate, cyclohexane, hiki ʻole ke hoʻoheheʻe ʻia i ka n-hexane, solvent gasoline, akā hiki ke hoʻoheheʻe ʻia i nā ʻāpana kūpono o nā mea hoʻoheheʻe maikaʻi. i ka aila mea kanu a me ka aila mineral me ka hemo ole.
