Nā waiwai palaki o ka laholio maʻamau

1. Laho maoli
He mea maʻalahi ka loaʻa ʻana o ka plasticity o ka laholio kūlohelohe. ʻO ka viscosity mau a me ka viscosity haʻahaʻa o ka laholio maleic maʻamau he haʻahaʻa ka viscosity mua a ʻaʻole pono e plasticated. Inā ʻoi aku ka viscosity Mooney o nā ʻano mea hoʻopili maʻamau ʻē aʻe ma mua o 60, pono nō lākou e hoʻoheheʻe ʻia. Ke hoʻohana nei i kahi mea hoʻohuihui kūloko no ka hoʻoheheʻe ʻana, ʻo ka manawa ma kahi o 3-5 mau minuke ke piʻi ka mahana ma luna o 120 ℃. Ke hoʻohui nei i nā plasticizers a i ʻole nā ​​plasticizers, hiki iā ia ke hoʻopōkole nui i ka manawa plasticizing a hoʻomaikaʻi i ka hopena plasticizing.
2. Styrene-butadiene
Ma ke ʻano laulā, ʻo ka mānoanoa o Mooney o Styrene-butadiene ma waena o 35-60. No laila, ʻaʻole pono ʻo Styrene-butadiene i ka plasticizing. Akā ʻo ka ʻoiaʻiʻo, ma hope o ka plasticizing, hiki ke hoʻomaikaʻi ʻia ka dispersibility o ka mea hoʻohuihui, kahi e kōkua ai i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana. ʻOi loa no nā huahana rubber sponge, maʻalahi ka Styrene-butadiene e huʻa ma hope o ka plasticizing, a like ka nui o ka pehu.
3. Polybutadiene
He ʻano kahe anu ko Polybutadiene a ʻaʻole maʻalahi ka hoʻomaikaʻi ʻana i ka hopena plasticizing. I kēia manawa, ua hoʻomalu ʻia ka viscosity Mooney o ka Polybutadiene i hoʻohana pinepine ʻia ma kahi pae kūpono i ka wā polymerization, no laila hiki ke kāwili pololei ʻia me ka ʻole o ka plasticizing.
4. Neoprene
ʻAʻole pono ka Neoprene e plasticized, akā no kona paʻakikī kiʻekiʻe, he mea kōkua ia no ka hana. ʻO ka mahana pass lahilahi maʻamau he 30 ℃ -40 ℃, kahi maʻalahi ke hoʻopili i ka ʻōwili inā kiʻekiʻe loa.
5. ʻEthylene propylene rubber
Ma muli o ke ʻano piha o ke kaulahao nui o ka ʻEthylene propylene rubber, he paʻakikī ke hana i ka haki ʻana o ka molekala ma o ka plasticating. No laila, he mea kūpono ke synthesize iā ia e loaʻa ai kahi viscosity Mooney kūpono me ka ʻole o ka pono no ka hoʻoheheʻe ʻana.
6. ʻŌpala Butyl
He paʻa a palupalu ke ʻano kemika o ka butyl rubber, he kaumaha molekala liʻiliʻi a he nui ka wai, no laila ʻaʻole maikaʻi ka hopena plasticizing mechanical. Hiki ke hoʻohui pololei ʻia ka butyl rubber me ka viscosity Mooney haʻahaʻa me ka ʻole o ka plasticizing.
7. ʻŌpala Nitrile
He liʻiliʻi ka plasticity o ka nitrile rubber, he kiʻekiʻe ka paʻakikī a he nui ka wela i ka wā o ka plasticating. No laila, hoʻohana pinepine ʻia ka mahana haʻahaʻa, ka mana haʻahaʻa a me ka plasticating segmented i ka wili hāmama e hoʻokō i nā hopena maikaʻi. ʻAʻole pono e plasticize ʻia ka nitrile rubber i loko o ka mīkini kāwili kūloko. No ka mea, he ʻano plasticity ko ka nitrile rubber palupalu, hiki ke hoʻohui pololei ʻia me ka ʻole o ka hoʻomaʻemaʻe ʻana i ka plastic.
