Sebacic Acid (CAS # 111-20-6)
Palapala noi
Hoʻohana nui ʻia ia ma ke ʻano he mea maka no ka sebacate plasticizer a me ka nylon molding resin, a hiki ke hoʻohana ʻia e like me ka mea maka no ka aila lubricating kiʻekiʻe. ʻO kāna huahana ester nui ka methyl ester, isopropyl Ester, butyl ester, octyl Ester, nonyl ester a me benzyl ester, nā esters maʻamau ka dibutyl sebacate a me ka sebacic acid dioctyl grains.
Hiki ke hoʻohana nui ʻia ʻo Decyl Diester plasticizer i ka polyvinyl chloride, alkyd resin, polyester resin a me polyamide molding resin, no ka haʻahaʻa haʻahaʻa a me ke kūpaʻa wela kiʻekiʻe, hoʻohana pinepine ʻia i kekahi resin kumu kūikawā. ʻO ka resin molding nylon i hana ʻia mai ka waikawa sebacic he paʻakikī kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, a hiki ke hana ʻia i nā huahana kumu kūikawā. ʻO ka waika Sebacic kekahi mea maka no nā mea hoʻomaʻemaʻe kino, surfactants, uhi a me nā mea ʻala.

Palekana
ʻAʻole ʻona ka waika Sebacic, akā ʻo ka cresol i hoʻohana ʻia i ka hana ʻana he mea ʻawaʻawa a pono e pale ʻia mai ka make ʻana (e ʻike i ka cresol). Pono e pani ʻia nā mea hana hana. Pono nā mea hana e hoʻohana i nā masks a me nā mīkina lima.
Hoʻopaʻa a mālama
Hoʻopili ʻia i loko o nā ʻeke i ulana ʻia a i ʻole hemp i hoʻopaʻa ʻia me nā ʻeke plastik, ʻo kēlā me kēia ʻeke he 25kg, 40kg, 50kg a i ʻole 500kg. E mālama i kahi anuanu a me ka makani, ke ahi a me ka wai. Mai hui pū me ka waiʻakika wai a me ka alkali. E like me nā ʻōlelo o ka mālama ʻana a me ka lawe ʻana.
Hoʻolauna
Ke hoʻolauna nei i ka Sebacic Acid - ke aniani keʻokeʻo keʻokeʻo i ulu nui i ka kaulana i nā makahiki, mahalo i kāna ʻano hana like ʻole ma nā ʻoihana lehulehu. ʻO ka waika Sebacic he waikawa dicarboxylic me ke ʻano kemika HOOC(CH2)8COOH a hiki ke hoʻoheheʻe ʻia i ka wai, ka waiʻona, a me ka etera. Loaʻa pinepine ʻia kēia ʻakika organik mai nā hua o ka mea kanu aila castor, a ʻo ia kekahi o nā mea waiwai nui i hoʻohana ʻia i ka ʻoihana kemika.
Hoʻohana nui ʻia ka waikawa Sebacic ma ke ʻano he mea maka no ka sebacate plasticizer a me ka resin molding nylon. ʻO kēia ma muli o kona hiki ke hoʻonui nui i ka elasticity a me ka maʻalahi o nā polymers like ʻole me ka ʻole o kā lākou hana a paʻa paha. Hoʻonui ia i ke kū'ē i nā wela wela, ʻoki, a me nā punctures a me ka hoʻomaikaʻi ʻana i ka ikaika tensile a me ka compressive o nā mea nylon. ʻO ka hopena, ua loaʻa ka ʻae ākea i ka ʻoihana plastic.
Hoʻohana nui ʻia ka Sebacic acid i ka hana ʻana i nā aila lubricating kūpaʻa kiʻekiʻe. Ma muli o kona kūlike me nā kaiapuni wela kiʻekiʻe, lawelawe ʻo ia ma ke ʻano he kumu maikaʻi loa no nā lubricants i nā ʻoihana kaʻa a me ka aerospace. ʻO kona ʻano paʻa wela e hiki ai ke hoʻomanawanui i nā noi wela kiʻekiʻe me ka hoʻohaʻahaʻa ʻana a me ka ʻaʻahu ʻoiai e hōʻoia ana i ka hilinaʻi a me ka hana.
ʻO kahi wahi ʻē aʻe kahi i ʻike ʻia ai ka hoʻohana ʻana o ka waika sebacic i ka hana ʻana i nā mea hoʻopili a me nā kemika kūikawā. Hoʻohana maʻamau ia i nā mea hoʻopili no ka maikaʻi o ka pulu a me ke komo ʻana. Hoʻohana ʻia ka waikawa Sebacic e hana i nā mea hoʻopili kiʻekiʻe no ka mea hiki ke hoʻomaikaʻi i nā waiwai adhesion o ka adhesive.
Hoʻohana pū ʻia ka Sebacic acid ma ke ʻano he mea pale i ka mālama wai a me ka hana ʻaila. ʻO kona kūpono i ka pale ʻana i ka ʻōpala a me ka oxidation e kūpono ia no nā pipelines a me nā mea hana ʻē aʻe i hoʻohana ʻia no ka lawe ʻana a me ka hana ʻana i ka aila a me ke kinoea maoli.
Ma muli o kona ʻano aniani keʻokeʻo keʻokeʻo, hiki ke ʻike maʻalahi i ka waika sebacic mai nā kemika ʻē aʻe. ʻO kēia ka mea i hoʻokomo maikaʻi ʻia no ka ʻoihana lāʻau lapaʻau ma ke ʻano he excipient. Hiki ke hoʻohana ʻia ma ke ʻano he diluent, binder a me ka lubricant i ka hana ʻana i nā ʻano like ʻole e like me nā papa, capsules, a me nā suppositories.
I ka hopena, ʻo ka versatility o ka waikawa sebacic a me ka laulā o nā noi e lilo ia i huahana hoihoi loa no ka hoʻohana ʻana ma nā ʻoihana he nui mai ka automotive a me ka aerospace a hiki i ka lāʻau lapaʻau a me ka hana kemika. ʻO kona kūpaʻa ma lalo o nā kūlana koʻikoʻi he mea nui ia i ka nui o nā ʻoihana me ka plastic, ka aila, ke kinoea, a me ka mālama wai, ʻoiai ʻo kona hiki ke hoʻonui i ka hana o nā polymers e hōʻike ana i kona waiwai. ʻO ka holoʻokoʻa, ʻo ka waika sebacic kahi poloka kūkulu koʻikoʻi no nā huahana he nui i lilo i mea nui i ke ola hou.
