ʻO ka paraffin chlorinated he wai melemele gula a ʻalani paha, ʻaʻole hiki ke lapalapa, ʻaʻole pahū, a haʻahaʻa loa ka volatility. Hoʻoheheʻe ʻia i loko o ka hapa nui o nā mea hoʻoheheʻe organik, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol. Ke hoʻomehana ʻia ma luna o 120 ℃, e palaho mālie ia iā ia iho a hiki ke hoʻokuʻu i ke kinoea hydrogen chloride. A ʻo nā oxides o ka hao, zinc, a me nā metala ʻē aʻe e hoʻolaha i kona palaho. ʻO ka paraffin chlorinated kahi plasticizer kōkua no ka polyvinyl chloride. Haʻahaʻa ka volatility, ʻaʻole hiki ke lapalapa, ʻaʻohe ʻala. Hoʻololi kēia huahana i kahi ʻāpana o ka plasticizer nui, hiki ke hōʻemi i ke kumukūʻai o ka huahana a hōʻemi i ke ahi.
Nā Hiʻohiʻona
ʻOi aku ka haʻahaʻa o ka hana plasticizing o ka chlorinated paraffin 52 ma mua o ka plasticizer nui, akā hiki iā ia ke hoʻonui i ka insulation uila a me ke kū'ē ʻana i ka lapalapa a hiki ke hoʻomaikaʻi i ka ikaika tensile. ʻO nā hemahema o ka chlorinated paraffin 52, ʻo ia ka maikaʻi ʻole o ke kū'ē ʻana i ka ʻelemakule a me ke kū'ē ʻana i ka mahana haʻahaʻa, ʻaʻole maikaʻi hoʻi ka hopena hana hou lua, a kiʻekiʻe ka viscosity. Eia nō naʻe, ma lalo o ke kūlana he kakaikahi a pipiʻi hoʻi ka plasticizer nui, noho mau ka chlorinated paraffin 52 i kahi ʻāpana o ka mākeke.
Hiki ke hoʻohuihui ʻia ka paraffin chlorinated 52 me nā mea e pili ana i ka ester, hiki iā ia ke hana i kahi plasticizer ma hope o ke kāwili ʻana. Eia kekahi, loaʻa iā ia nā ʻano he flame retardant a me ka lubrication. Inā pono, hiki iā ia ke pāʻani i kahi hana i ka antisepsis.
He ikaika loa ka hiki ke hana o ka paraffin chlorinated 52. I ke kaʻina hana noi, hoʻohana nui ʻia ke ʻano chlorination thermal a me ke ʻano chlorination catalytic. I nā hihia kūikawā, hoʻohana ʻia nā ʻano photochlorination.
Noi
1. ʻAʻole hiki ke hoʻoheheʻe ʻia ka paraffin 52 i ka wai, no laila hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha i nā uhi e hōʻemi i ke kumukūʻai, hoʻonui i nā waiwai kūpono a me ka pale wai a me ke ahi.
2. Hoʻohana ʻia i nā huahana PVC ma ke ʻano he plasticizer a i ʻole ka plasticizer kōkua, ʻoi aku ka maikaʻi o kona kūlike a me ke kūpaʻa wela ma mua o ka chlorinated paraffin-42.
3. Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻohui i ka laholio, ka pena, a me ka wai ʻoki e pāʻani i ke kuleana o ke kū'ē ʻana i ke ahi, ke kū'ē ʻana i ka lapalapa, a hoʻomaikaʻi i ka pololei o ka ʻoki ʻana, a pēlā aku.
4. Hiki ke hoʻohana ʻia ma ke ʻano he anticoagulant a me kahi mea anti-extrusion no nā aila lubricating.
