He aha ka NBR-PVC Blend?
ʻO ka hui ʻana o nā polymers ua loaʻa ka hoihoi nui ma muli o ka hiki ke hoʻohana ʻia e hana i nā mea polymeric hou me nā waiwai kikoʻī kūpono no kekahi mau noi kūikawā.Ua hoʻolālā ʻia nā hui ʻana mai ka acrylonitrile butadiene rubber (NBR) a me ka polyvinyl chloride (PVC) no nā huahana e hana pū ana me nā aila.Hāʻawi ka ʻāpana PVC i ka hoʻonui ʻana i ka ozone, ka lapalapa a me ka pale ʻana i ka wā, ʻoiai ʻo ka ʻāpana NBR e hāʻawi i ka abrasion maikaʻi a me ke kūpaʻa kemika me ka aila, nā wahie, a me nā pūhui nonpolar ʻē aʻe.
Hoʻohana ʻia nā elastomers NBR/PVC i nā ʻoihana he nui a me nā mākeke e pili ana i nā lako, hale a me ke kūkulu ʻana, nā kaʻa kaʻa, nā kāmaʻa, nā ʻoihana a me nā mea hale, a me nā meaʻai.ʻO kekahi mau noi nui e pili ana i nā kapuaʻi kāmaʻa palekana, nā wili paʻi palupalu, ka papahele ʻoihana, nā ʻeke kaula kala a me nā uhi hose kala.
ʻO ka hana o ka NBR i loko o ka pūhui PVC hiki ke hoʻololi ʻia
ʻO ka hoʻohui ʻana o PVC i ka NBR e hoʻonui i ka hiki ke lawe i ka puaʻa i loko o nā pūhui kala, e hopena i ka paʻa ʻana o nā kala ʻālohilohi.Hōʻike pū ka hui ʻana i ka volatility plasticizer haʻahaʻa ma muli o ka pilina ikaika o ka nitrile rubber no nā plasticizers wai maʻamau.1
Ma muli o ka maʻiʻo PVC a me ka plasticizer, hāʻawi nā hui NBR-PVC i ka elasticity, hoʻonui i ke kūpaʻa hoʻonohonoho hoʻokūkū, a me ka maʻalahi haʻahaʻa haʻahaʻa.ʻO ka maʻamau, piʻi ka elongation i ka wā hoʻomaha me ka piʻi ʻana o ka pae o ka NBR aʻo ka piʻi ʻana o ka ikaika tensile me ka piʻi ʻana o ka pae o PVC.
Hiki ke lilo i ka plasticizer PVC maʻalahi me ka plasticizer maʻamau ma lalo o kekahi mau kūlana a lilo i ʻoʻoleʻa a palupalu.I ka hui ʻana me ka wahie, hoʻemi ʻo NBR i ka unuhi ʻana o ka plasticizer.ʻO ka PVC maʻalahi i hoʻololi ʻia me ka NBR e nalowale ke kaumaha i ka wā e pili ana me nā aila.No laila, mālama ʻia ka maʻalahi a me ke ola lawelawe lōʻihi.
Nā Pono NBR Rubber Nitrile
1. Hoʻomau Plasticizer:Hiki i ka NBR ke hoʻonui i ka PVC elasticity o ka huahana a hoʻemi i ka nui o ka plasticizer i hoʻohana ʻia;i ka manawa like, no ka huki ʻana i nā plasticizer a hoʻemi i ka wikiwiki o ka neʻe ʻana o nā plasticizers.
2. Kūʻē maikaʻi loai ka aila, wahie, hydrolysis a me nā kemika: NBR he nui ka nui o CN pūʻulu, hiki ke hoʻomaikaʻi nui i ka aila a me ka pale pale o PVC.
3. Maikaʻi haʻahaʻa wela hikiwawe:ʻAʻohe ʻano kaulahao maʻalahi a elastic i loko o ka mole PVC, no laila maikaʻi ʻole kāna hana ma ka wela haʻahaʻa.Ma hope o ka hoʻohui ʻana i ka elastomer PNBR, hoʻomaikaʻi ʻia kona kūpaʻa haʻahaʻa haʻahaʻa.
4. ʻOi aku ka maikaʻi o ka abrasion.Hiki i ka NBR ke hoʻomaikaʻi nui i ka pale ʻana o PVC a hoʻolōʻihi i ke ola lawelawe o nā huahana.
5. ʻO ke kūlana kūpaʻa maikaʻi:ʻO ka melt viscosity o NBR/PVC he paʻa paʻa i kahi ākea ākea, kahi e hoʻomaha ai i nā kūlana hana o ka huahana.
6. Hiki lōʻihi loa:Ma ke ʻano he elastomer, hana ʻo NBR i kahi "sea-island" i ka wā i hui ʻia me PVC, kahi e hoʻomaikaʻi nui ai i ka maʻalahi o PVC.
7. Paʻi Rubber:ʻO ka hui PVC me ka NBR ke nānā a hoʻopā ʻia e like me ka Rubber.
8. Hoʻopili maikaʻi loa：Hiki i ka hoʻohui ʻana i ka NBR ke hoʻomaikaʻi i ka hana kūʻē o ka huahana.

ʻO INPVC kahi hui hana PVC i hoʻokele maikaʻi ʻia e hana i ka NBR PVC.Ua hoʻonoho mākou i kahi hōʻailona no ka maikaʻi ma ka ʻoihana.ʻIke nui ʻia kā mākou hui ʻana no ko lākou kūpaʻa a me ke kūpaʻa ʻana i ka ʻaila.Loaʻa i nā mea i hoʻohui ʻia i kahi kaʻina hana kiʻekiʻe e hiki ai i kā mākou huahana ke hoʻokō a ʻoi aku paha i nā kikoʻī.
