ʻO nā surfactants e pili ana i nā mea hiki ke hoʻemi nui i ka ʻili o ka ʻili o ka hopena i manaʻo ʻia, ma ke ʻano he mau pūʻulu hydrophilic a lipophilic i hiki ke hoʻonohonoho ʻia ma ke ʻano kuhikuhi ma ka ʻili o ka hopena.Hoʻokomo nui nā mea hoʻoheheʻe i ʻelua mau ʻāpana: nā surfactants ionic a me nā surfactants non ionic.Hoʻokomo pū ʻia nā mea hoʻoheheʻe Ionic i ʻekolu mau ʻano: nā mea hoʻokuʻu anionic, nā surfactants cationic, a me nā surfactants zwitterionic.
ʻO ka upstream o ke kaulahao ʻoihana surfactant ka hoʻolako ʻana i nā mea maka e like me ka ethylene, fatty alcohols, fatty acids, palm oil, and ethylene oxide;ʻO ka midstream ke kuleana no ka hana ʻana a me ka hana ʻana i nā huahana like ʻole, me nā polyols, polyoxyethylene ethers, fatty alcohol ether sulfates, etc;I lalo, ua hoʻohana nui ʻia i nā kula e like me ka meaʻai, nā mea hoʻomaʻemaʻe, ka hoʻomaʻemaʻe ʻoihana, ka paʻi lole a me ke kala, a me nā huahana holoi.
Mai ka hiʻohiʻona o ka mākeke o lalo, ʻo ka ʻoihana detergent ke kahua noi nui o nā surfactants, ʻoi aku ma mua o 50% o ka noi o lalo.ʻO nā mea hoʻomaʻemaʻe, hoʻomaʻemaʻe ʻenehana, a me ka paʻi lole a me ka waihoʻoluʻu nā helu āpau ma kahi o 10%.Me ka hoʻomau mau ʻana o ka hoʻokele waiwai o Kina a me ka hoʻonui ʻana i ka nui o ka hana ʻenehana, ua hoʻomau ka hana holoʻokoʻa a me ke kūʻai ʻana o nā surfactants i kahi ʻano piʻi.I ka makahiki 2022, ua ʻoi aku ka hana o nā surfactants ma Kina ma mua o 4.25 miliona tons, kahi hoʻonui makahiki-ma-makahiki ma kahi o 4%, a ʻo ka nui o ke kūʻai aku ma kahi o 4.2 miliona tons, hoʻonui i ka makahiki ma kahi o 2%.
ʻO Kina ka mea hana nui o nā surfactants.Me ka holomua mau o ka ʻenehana hana, ua loaʻa mālie kā mākou huahana i ka mākeke honua ma muli o ko lākou maikaʻi a me nā pono hana, a loaʻa kahi mākeke ākea ākea.I kēia mau makahiki i hala iho nei, ua hoʻomau ka nui o nā mea e hoʻokuʻu aku ai i ka ulu.I ka makahiki 2022, ʻo ka nui o ka hoʻokuʻu aku o nā surfactants ma Kina ma kahi o 870000 tons, kahi hoʻonui makahiki ma kahi o 20%, ka mea nui i lawe ʻia i nā ʻāina a me nā wahi e like me Russia, Iapana, Philippines, Vietnam, Indonesia, etc.
Mai ka hiʻohiʻona o ka hoʻolālā hana, ʻo ka hana ʻana o nā surfactants non-ionic ma Kina i ka makahiki 2022 ma kahi o 2.1 miliona tons, e helu ana no kahi kokoke i 50% o ka nui o ka hana ʻana o nā surfactants, ka pae mua.ʻO ka hana ʻana o nā mea hoʻoheheʻe anionic ma kahi o 1.7 miliona tons, e helu ana ma kahi o 40%, ke kūlana lua.ʻO nā mea ʻelua nā huahana mahele nui o nā surfactants.
I nā makahiki i hala iho nei, ua hoʻopuka ka ʻāina i nā kulekele e like me ka "14th Five Year Plan for High Quality Development of the Surfactant Industry", ka "14th Five Year Plan for High Quality Development of China's Detergent Industry", a me ka "14th Five Year Plan. for Green Industrial Development" e hoʻokumu i kahi kūlana hoʻomohala maikaʻi no ka ʻoihana surfactant, hoʻoikaika i ka hoʻololi ʻana a me ka hoʻomaikaʻi ʻana i ka ʻoihana, a hoʻomohala i ka ʻōmaʻomaʻo, ka palekana o ke kaiapuni, a me ke ʻano kiʻekiʻe.
I kēia manawa, nui ka poʻe i komo i ka mākeke, a ʻoi aku ka ikaika o ka hoʻokūkū ʻoihana.I kēia manawa, aia kekahi mau pilikia i loko o ka ʻoihana surfactant, e like me ka ʻenehana hana kahiko, nā keʻena mālama kaiapuni substandard, a me ka lawa ʻole o nā huahana kiʻekiʻe.He wahi hoʻomohala koʻikoʻi ka ʻoihana.I ka wā e hiki mai ana, ma lalo o ke alakaʻi ʻana o nā kulekele aupuni a me ke koho ʻana i ke ola ʻana o ka mākeke a me ka hoʻopau ʻana, ʻo ka hui ʻana a me ka hoʻopau ʻana o nā ʻoihana i ka ʻoihana surfactant e lilo i mea maʻamau, a manaʻo ʻia e hoʻonui hou ʻia ka ʻoihana.
