Mea Hana Kumukūʻai Maikaʻi ʻOxalic Acid CAS：144-62-7
ʻO ka waikawa Oxalic kahi waikawa dicarboxylic ikaika e kū nei i loko o nā mea kanu a me nā mea kanu he nui, ma ke ʻano he paʻakai calcium a potassium paha. ʻO ka waikawa Oxalic wale nō ka hui hiki ke hui pololei ʻia nā hui carboxyl ʻelua; no kēia kumu ʻo ka waikawa oxalic kekahi o nā waikawa organik ikaika loa. ʻAʻole e like me nā waikawa carboxylic ʻē aʻe (koe wale nō ka waikawa formic), ua maʻalahi ka oxidized; ʻo kēia ka mea e pono ai ma ke ʻano he mea hōʻemi no ke kiʻi ʻana, ka hoʻokeʻokeʻo ʻana, a me ka wehe ʻana i ka ʻīnika. Hoʻomākaukau pinepine ʻia ka waikawa Oxalic ma ka hoʻomehana ʻana i ka sodium formate me ka sodium hydroxide e hana i ka sodium oxalate, kahi i hoʻololi ʻia i ka calcium oxalate a mālama ʻia me ka waikawa sulfuric e loaʻa ai ka waikawa oxalic manuahi.
He haʻahaʻa loa ka nui o ka waikawa oxalic i ka hapa nui o nā mea kanu a me nā meaʻai mea kanu, akā ua lawa ka spinach, chard a me nā greens beet e hoʻopilikia i ka omo ʻana o ka calcium i loaʻa i kēia mau mea kanu.
Hoʻopuka ʻia ia i loko o ke kino ma o ka metabolism o ka waikawa glyoxylic a i ʻole ka waikawa ascorbic. ʻAʻole ia e metabolized akā hoʻokuʻu ʻia i loko o ka mimi. Hoʻohana ʻia ia ma ke ʻano he reagent analytical a me ka mea hoʻemi maʻamau. ʻO ka waikawa Oxalic kahi acaricide kūlohelohe i hoʻohana ʻia no ka mālama ʻana i nā mites varroa i nā kolone me ka ʻole/haʻahaʻa brood, packages, a i ʻole swarms. Hoʻohana ʻia ka waikawa oxalic vaporized e kekahi poʻe mālama pi ma ke ʻano he insecticide e kūʻē i ka parasitic Varroa mite. -
Mea Hana Kumukūʻai Maikaʻi Xanthan Gum Papa ʻOihana CAS：11138-66-2
ʻO ka Xanthan gum, i ʻike ʻia hoʻi ʻo Hanseonggum, he ʻano microbial exopolysaccharide i hana ʻia e Xanthomnas campestris me ka carbohydrate ma ke ʻano he mea maka nui (e like me ka palaoa kulina) ma o ka ʻenekinia fermentation. Loaʻa iā ia ka rheology kū hoʻokahi, ka solubility maikaʻi i ka wai, ke kūpaʻa i ka wela a me ke kumu waikawa, a he kūpono maikaʻi me nā ʻano paʻakai like ʻole. Ma ke ʻano he mea hoʻomānoanoa, ka mea hoʻokuʻu, ka emulsifier, ka stabilizer, hiki ke hoʻohana nui ʻia i ka meaʻai, ka petroleum, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe ma mua o 20, ʻo ia ka pae hana nui loa o ka honua a me ka polysaccharide microbial i hoʻohana nui ʻia.
He pauka melemele māmā a keʻokeʻo paha ka ʻume Xanthan, he pilau iki. Hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, he hopena kūlike ʻole, kū i ka hau a me ka heheʻe ʻana, ʻaʻole hoʻoheheʻe ʻia i ka ethanol. Hoʻopuehu wai, emulsification i loko o kahi colloid viscous hydrophilic paʻa.

Kumukūʻai maikaʻi o ka mea hana DINP Papa ʻoihana CAS：28553-12-0
ʻO Diisononyl phthalate (DINP)：He wai ʻaila moakaka kēia huahana me kahi ʻala iki. He plasticizer nui ia me nā waiwai maikaʻi loa. Hiki ke hoʻoheheʻe ʻia kēia huahana i loko o ka PVC, a ʻaʻole e hoʻokahe ʻia ʻoiai inā hoʻohana ʻia i ka nui. ʻOi aku ka maikaʻi o ka volatilization, ka neʻe ʻana a me ka non-toxicity ma mua o DOP (dioctyl phthalate), hiki ke hāʻawi i ka huahana i ke kūpaʻa kukui maikaʻi, ke kūpaʻa wela, ke kūpaʻa ʻelemakule a me nā waiwai insulation uila, a ʻoi aku ka maikaʻi o ka hana piha ma mua o DOP. No ka mea, he kūpaʻa wai maikaʻi nā huahana i hana ʻia e kēia huahana a me ke kūpaʻa unuhi, haʻahaʻa ka toxicity, kūpaʻa ʻelemakule, hana insulation uila maikaʻi loa, no laila ua hoʻohana nui ʻia i loko o nā kiʻiʻoniʻoni pāʻani, uea, a me ke kaula.
Ke hoʻohālikelike ʻia me DOP, ʻoi aku ka nui a me ka lōʻihi o ke kaumaha molekala, no laila he ʻoi aku ka maikaʻi o ka hana ʻelemakule, ke kūʻē i ka neʻe ʻana, ka hana anticairy, a me ke kūʻē ʻana i ka mahana kiʻekiʻe. Pēlā nō, ma lalo o nā kūlana like, ʻoi aku ka ʻino o ka hopena plasticization o DINP ma mua o DOP. Manaʻo nui ʻia he ʻoi aku ka maikaʻi o ka DINP ma mua o DOP.
ʻOi aku ka maikaʻi o DINP i ka hoʻomaikaʻi ʻana i nā pono extrusion. Ma lalo o nā kūlana hana extrusion maʻamau, hiki iā DINP ke hōʻemi i ka viscosity heheʻe o ka hui ʻana ma mua o DOP, kahi e kōkua ai i ka hōʻemi ʻana i ke kaomi o ke kumu hoʻohālike awa, hōʻemi i ka ʻaʻahu mechanical a hoʻonui paha i ka huahana (a hiki i ka 21%). ʻAʻohe pono e hoʻololi i ke ʻano huahana a me ke kaʻina hana, ʻaʻohe hoʻopukapuka kālā hou aʻe, ʻaʻohe hoʻohana ikehu hou aʻe, a me ka mālama ʻana i ka maikaʻi o ka huahana.
He wai ʻaila ka DINP maʻamau, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai. Lawe pinepine ʻia e nā kaʻa tanker, nā bākeke hao liʻiliʻi a i ʻole nā barela plastik kūikawā.
ʻO kekahi o nā mea maka nui o DINP -INA (INA), i kēia manawa he kakaikahi wale nō nā ʻoihana ma ka honua e hiki ke hana, e like me Exxon Mobil o ʻAmelika Hui Pū ʻIa, ka ʻoihana lanakila o Kelemania, ka Concord Company o Iapana, a me ka ʻoihana ʻAsia Hema ma Taiwan. I kēia manawa, ʻaʻohe ʻoihana kūloko e hana ana i ka INA. Pono nā mea hana a pau e hana ana i ka DINP ma Kina e hele mai mai nā mea i lawe ʻia mai.
