ʻO Chloroprene rubber (CR), i ʻike ʻia ʻo chloroprene rubber, he elastomer i hana ʻia e ka alpha polymerization o chloroprene (ie, 2-chloro-1,3-butadiene) ma ke ʻano he kumu kumu.Ua hana mua ʻia e Wallace Hume Carothers o DuPont ma ʻApelila 17, 1930. Ua hoʻolaha ʻo DuPont i ka lehulehu ma Nowemapa 1931 ua hana ʻo ia i ka lāʻau chloroprene a hoʻolauna mua ia i ka mākeke i ka makahiki 1937, e hana ana i ka chloroprene rubber ka ʻano lāʻau synthetic mua loa i hana ʻia ma ka ʻoihana. .
ʻO nā waiwai lāʻau chloroprene.
ʻO ka hiʻohiʻona Neoprene he keʻokeʻo keʻokeʻo, beige a ʻulaʻula paha ʻulaʻula a i ʻole lumps, density 1.23-1.25g/cm3, aniani hoʻololi wela: 40-50°C, crumbling point: 35°C, palupalu ma kahi o 80°C, decomposition ma 230- 260°C.Hiki ke hoʻoheheʻe ʻia i loko o ka chloroform, benzene a me nā mea hoʻoheheʻe ʻē aʻe, pehu ʻia i loko o ka ʻaila ʻaila a me ka ʻaila mineral me ka ʻole o ka hoʻoheheʻe ʻana.Hiki ke hoʻohana ʻia ka 80-100 ° C no ka manawa lōʻihi, me ke ʻano o ka hoʻopaʻa ahi.
ʻO ka ʻokoʻa ka hui ʻana o ka hui neoprene i loko o ka hui neoprene e hoʻololi i ka hui methyl i loko o ka ʻōpala maoli, kahi e hoʻomaikaʻi ai i ka pale ʻana o ka ozone, ka pale ʻana i ka aila a me ka pale wela o ka lāʻau neoprene.I ka pōkole, he maikaʻi ke kū'ē i ka wā, ke kū'ē ozone, ke kū'ēʻana i ke kino, kaʻaila, a me nā mea'ē aʻe.No laila, he mea maʻalahi loa ka neoprene, ma ke ʻano he lāʻau lapaʻau nui a me kahi pahu kūikawā.
ʻO nā waiwai kino nui a me nā mechanical penei:
1.Ka ikaika o ka lāʻau neoprene
ʻO nā waiwai tensile o ka neoprene ua like ia me nā mea o ka ʻōpala maoli, a ʻo kona ʻōpala maka he kiʻekiʻe ka ikaika tensile a me ka elongation i ka wā haki, ʻo ia ka mea hoʻoikaika kino;ʻO ka molecular structure o neoprene he molekala maʻamau, a aia i ke kaulahao nā pūʻulu polar o nā ʻātoma chlorine, kahi e hoʻonui ai i ka ikaika intermolecular.No laila, ma lalo o ka hana o nā mana o waho, ua maʻalahi ke kikoo a me ka crystallize (hoʻoikaika ponoʻī), a ʻaʻole maʻalahi ka paheʻe intermolecular.Eia kekahi, ʻoi aku ka nui o ke kaumaha mole (2.0 ~ 200,000), no laila ʻoi aku ka nui o ka ikaika tensile.
2.Excellent elemakule kū'ē
ʻO nā ʻātoma chlorine i hoʻopili ʻia i ka paʻa pālua o ke kaulahao mole neoprene e hana i ka paʻa pālua a lilo nā ʻātoma chlorine i mea ʻole, no laila ua maikaʻi ka paʻa o ka mālama ʻana i kāna ʻōpala vulcanized;ʻAʻole maʻalahi ka hopena i ka wela, ka oxygen a me ka māmā i ka lewa, e hōʻike ana i ke kūpaʻa ʻelemakule maikaʻi loa (ke kū'ē i ka wā, ka pale ozone a me ka pale wela).ʻO kona kūpaʻa ʻelemakule, ʻoi aku ka ʻoi aku ka pale ʻana i ka wā a me ka ozone, ʻo ia ka lua o ka ethylene propylene rubber a me ka butyl rubber i ka lāʻau kumu nui, a ʻoi aku ka maikaʻi ma mua o ka lāʻau maoli;ʻOi aku ka maikaʻi o kona kūpaʻa wela ma mua o ka lāʻau maoli a me ka styrene butadiene rubber, a like me ka nitrile rubber, hiki ke hoʻohana ʻia no ka manawa pōkole ma 150 ℃, a hiki ke hoʻohana ʻia no ka lōʻihi o 4 mau mahina ma 90-110 ℃.
3.Excellent lapalapa-kū'ē
ʻO ka Neoprene ka lāʻau lapaʻau maikaʻi loa, loaʻa iā ia nā hiʻohiʻona o ka hoʻopau ʻole ʻana, hiki ke hoʻopili ʻia me ka lapalapa ahi, akā ua pio ka lapalapa i hoʻokaʻawale ʻia, ʻo ia ke kumu o ke ahi neoprene, hiki ke decomposed ke kuleana o ke kiʻekiʻe ma lalo o ke kuleana o hydrogen chloride gas a hoʻopau i ke ahi.
4.Excellent kaʻaila kū'ē, pale pale
ʻO ke kūpaʻa ʻaila o ka lāʻau neoprene ka lua wale nō i ka nitrile rubber a ʻoi aku ka maikaʻi ma mua o nā ʻōpala maʻamau.ʻO kēia ke kumu o ka mole neoprene i loaʻa nā polar chlorine atoms, kahi e hoʻonui ai i ka polarity o ka mole.ʻOi aku ka maikaʻi o ke kūpaʻa kemika o ka neoprene, koe wale nō ka waikawa oxidizing ikaika, ʻaʻohe hopena o nā waikawa ʻē aʻe a me nā alkali.ʻOi aku ka maikaʻi o ke kūpaʻa wai o ka neoprene ma mua o nā ʻāpana synthetic ʻē aʻe.
He aha nā wahi noi o neoprene?
Hoʻohana ʻia ʻo Neoprene i nā ʻano hana like ʻole, ka mea nui no nā huahana kūʻokoʻa, e like me nā uwea uila, nā ʻili kaula, nā pillow pads, nā ʻaoʻao o nā paikikala paʻa, nā dam dams, etc.;ʻO nā huahana pale wela a me ka lapalapa ahi, e like me nā kāʻei conveyor pale wela, nā hoses, nā ʻōpala, etc.;ʻO nā huahana kūpaʻa ʻaila a me nā mea kemika, e like me nā paipu, nā wili wili, nā ʻāpana ʻōpala, nā kaʻa a me nā ʻāpana tractor;ʻO nā huahana ʻē aʻe e like me ka lole lole, nā kāmaʻa a me nā mea hoʻopili, etc.
1. Uea a me nā mea uhi kaula
ʻO ka Neoprene ka pale o ka lā, pale i ka ozone, a he maikaʻi ʻole ka flammability, ʻo ia ke kumu uea kūpono no nā mines, nā moku, ʻoi aku hoʻi no ka hana ʻana i ke kaula sheathing, akā hoʻohana pinepine ʻia no nā kaʻa, nā mokulele, nā uwea hoʻoheheʻe engine, nā kaula mana mana atomic. a me na uwea kelepona.Me ka neoprene no ka ʻaʻahu o ka uea a me ke kaula i kona hoʻohana palekana ʻana ma mua o ka ʻōpala maoli ma mua o 2 mau manawa lōʻihi.
2. Ke kāʻei lawe, kāʻei hoʻouna
Loaʻa i ka Neoprene nā waiwai mechanical maikaʻi loa, kūpono loa no ka hana ʻana i nā kāʻei halihali a me nā kāʻei hoʻouna, ʻoi aku ka maikaʻi o kāna hana ʻana i nā kāʻei hoʻouna ʻoi aku ka maikaʻi ma mua o nā mea ʻē aʻe.
3.Oil resistant hose, gasket, anti-corrosion Murari
Ma muli o kona kūpaʻa aila maikaʻi, ke kūpaʻa kino kino, ka wela a me nā ʻano ʻē aʻe, hoʻohana nui ʻia ka neoprene i ka hana ʻana i nā huahana ʻaila-ʻole a me nā ʻano like ʻole o nā hoses, tapes, gaskets a me nā mea hoʻonaninani corrosion-resistant lining, ʻoi aku ka wela. nā kāʻei conveyor, ka aila a me ka waika a me nā paipu kūpaʻa alkali, etc.
4.Gasket, kākoʻo pad
He maikaʻi ka hoʻopaʻa ʻana a me ke kūpaʻa ʻana o ka Neoprene, ʻoi aku ka nui o nā ʻāpana kaʻa i hana ʻia me ka neoprene, e like me nā puka makani, nā hoses o nā gaskets like ʻole, a me nā mea ʻē aʻe, akā hoʻohana ʻia ma ke ʻano he alahaka, mine lift truck, oil tank support pad.
5.Adhesive, sealant
ʻO ka neoprene adhesive i hana ʻia me ka neoprene rubber e like me ka mea nui o ka maka he hiki ke maʻalahi, a me ke kūpaʻa ʻelemakule, ke kūpaʻa kemika a me ka pale ʻaila, a me ka ikaika paʻa kiʻekiʻe.
ʻAʻole i loaʻa i ka neoprene latex nā mea hoʻoheheʻe kūlohelohe, no laila, loaʻa iā ia nā pōmaikaʻi i ka palekana a me ke olakino, kahi e hiki ai ke hoʻohana ʻia ka carboxyl neoprene ma ke ʻano he mea hoʻopili no ka lāʻau a me ke kila.He polarity ka chloroprene rubber, no laila he nui ka noi ʻana o ka substrate hoʻopaʻa ʻana, no ka aniani, ka hao, ka PVC paʻakikī, ka lāʻau, ka plywood, ka aluminika, nā ʻano like ʻole o ka vulcanized rubber, ka ʻili a me nā mea hoʻopili ʻē aʻe.
6. Nā huahana'ē aʻe
Hoʻohana nui ʻia ʻo Neoprene i ke kahua o ka halihali a me ke kūkulu ʻana.E like me ka hoʻohana ʻana i ka neoprene foam cushion noho i ke kaʻa a me ke kaʻa kaʻa, hiki ke pale i ke ahi;nā mokulele, me nā huila kūlohelohe a me nā neoprene e hana i nā ʻāpana pale ʻaila;ʻenekini me nā ʻāpana lāʻau, gaskets, sila, etc.;ke kūkulu ʻana, hoʻohana ʻia i ka gasket hale kiʻekiʻe, palekana a me ka shockproof;Hiki ke hoʻohana ʻia ka neoprene e like me ka embankment artificial, interceptor ma ke sila nunui, paʻi ʻana, dyeing, paʻi, pepa a me nā ʻoihana ʻenehana ʻoihana ʻē aʻe Hiki ke hoʻohana ʻia ʻo Neoprene e like me ke ea cushion, ea ʻeke, nā mea mālama ola, adhesive tape, etc.
