Ua kūkulu ʻia nā polymers super absorbent i ka hopena o 1960s. I ka makahiki 1961, ua hoʻopili ka Northern Research Institute o ka US Department of Agriculture i ka starch i ka acrylonitrile no ka manawa mua e hana i ka HSPAN starch acrylonitrile graft copolymer i ʻoi aku ma mua o nā mea wai kuʻuna. I ka makahiki 1978, ua alakaʻi ʻo Sanyo Chemical Co., Ltd. o Iapana i ka hoʻohana ʻana i nā polymers super absorbent no nā diapers hoʻokuʻu ʻia, a ua hoʻohuli ʻia ka manaʻo o nā ʻepekema mai nā wahi a pau. I ka hopena o nā makahiki 1970, ua manaʻo ʻo UCC Corporation o ʻAmelika Hui Pū ʻIa e hoʻopili i nā polymers olefin oxide me ka mālama ʻana i ka radiation, a synthesized non-ionic super absorbent polymers me ka wai absorption capacity o 2000 mau manawa, pēlā e wehe ai i ka synthesis o non-ionic. nā polymers hoʻoheheʻe nui. Puka. I ka makahiki 1983, ua hoʻohana ʻo Sanyo Chemical o Iapana i ka potassium acrylate i mua o nā pūhui diene e like me ka methacrylamide e polymerize i nā polymers superabsorbent. Ma hope o kēlā, ua hoʻomau ka hui i nā ʻōnaehana polymer superabsorbent i haku ʻia me ka polyacrylic acid i hoʻololi ʻia a me ka polyacrylamide. I ka pau ʻana o ke kenekulia i hala, ua hoʻomohala ʻia nā ʻepekema mai nā ʻāina like ʻole a hana i nā polymers superabsorbent e ulu wikiwiki i nā ʻāina a puni ka honua. I kēia manawa, ua hoʻokumu nā hui hana nui ʻekolu o Iapana Shokubai, Sanyo Chemical a me Stockhausen o Kelemania i kahi kūlana ʻekolu wāwae. Mālama lākou i ka 70% o ka mākeke honua i kēia lā, a ke alakaʻi nei lākou i nā hana hui honua ma o ka hui ʻenehana e monopoli i ka mākeke kiʻekiʻe o nā ʻāina āpau o ka honua. Pono e kūʻai aku i nā polymers hoʻoheheʻe wai. Loaʻa i nā polymers super absorbent ka nui o ka hoʻohana ʻana a me nā manaʻo noiʻi ākea loa. I kēia manawa, ʻo kāna hoʻohana nui ʻana i nā huahana maʻemaʻe, e helu ana ma kahi o 70% o ka mākeke holoʻokoʻa.
Mai ka sodium polyacrylate superabsorbent resin he nui ka wai hoʻoheheʻe wai a me ka maikaʻi o ka mālama ʻana i ka wai, loaʻa ka nui o nā noi ma ke ʻano he mea mālama wai lepo i ka mahiʻai a me ka ulu lāʻau. Inā hoʻohui ʻia kahi mea liʻiliʻi o ka sodium polyacrylate super absorbent i ka lepo, hiki ke hoʻomaikaʻi ʻia ka germination rate o kekahi mau pī a me ke kūpaʻa maloʻo o nā ʻōpuʻu pi, a hiki ke hoʻonui ʻia ka ea permeability o ka lepo. Eia kekahi, ma muli o ka hydrophilicity a me ka maikaʻi anti-fogging a me nā waiwai anti-condensation o super absorbent resin, hiki ke hoʻohana ʻia e like me kahi mea hoʻopihapiha hou. Hiki i ke kiʻi ʻoniʻoni i hana ʻia i nā waiwai kūʻokoʻa o ka super absorbent polymer hiki ke mālama pono i ka hou o ka meaʻai. ʻO ka hoʻohui ʻana i kahi liʻiliʻi o ka polymer super absorbent i nā mea hoʻonaninani hiki ke hoʻonui i ka viscosity o ka emulsion, ʻo ia ka mānoanoa kūpono. Ke hoʻohana nei i nā hiʻohiʻona o ka polymer super absorbent e hoʻoheheʻe wale i ka wai akā ʻaʻole ka aila a i ʻole nā mea hoʻoheheʻe organik, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe wai i ka ʻoihana.
No ka mea, ʻaʻole ʻona nā polymers super absorbent, ʻaʻole hoʻonāukiuki i ke kino o ke kanaka, nā hopena ʻaoʻao ʻole, a me ka coagulation koko ʻole, ua hoʻohana nui ʻia lākou i ka lāʻau lapaʻau i nā makahiki i hala. No ka laʻana, hoʻohana ʻia ia no ka ʻaila topical me ka nui o ka wai a me ka ʻoluʻolu e hoʻohana; e hana i nā kāʻei lapaʻau a me nā pōpō pulupulu e hiki ke komo i ke koko a me nā mea huna mai ka ʻoki ʻana a me ka ʻeha, a hiki ke pale i ka suppuration; e hana i nā lāʻau anti-bacterial e hiki ke hele i ka wai a me nā lāʻau lapaʻau akā ʻaʻole nā microorganism. ʻili hana maʻi maʻi, etc.
Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ua ʻoi aku ka nui o ka nānā ʻana i ka mālama ʻana i ke kaiapuni. Inā hoʻokomo ʻia ka polymer super absorbent i loko o kahi ʻeke i hiki ke hoʻoheheʻe ʻia i loko o ka wai, a hoʻokomo ʻia ka ʻeke i loko o ka wai, i ka wā e hoʻoheheʻe ʻia ai ka ʻeke, hiki i ka polymer super absorbent ke komo koke i ka wai e hoʻopaʻa i ka wai.
I loko o ka ʻoihana uila, hiki ke hoʻohana ʻia nā polymers super absorbent e like me nā mea ʻike haʻahaʻa, nā ʻike ana i ka wai, a me nā mea ʻike leak wai. Hiki ke hoʻohana ʻia nā polymers super absorbent e like me nā adsorbents ion metala kaumaha a me nā mea hoʻohana ʻaila.
I ka pōkole, ʻo ka polymer super-absorbent he ʻano mea polymer me kahi ākea ākea o ka hoʻohana. ʻO ka hoʻomohala ikaika ʻana o ka resin polymer super-absorbent he mau mākeke nui. I kēia makahiki, ma lalo o nā kūlana o ka maloʻo a me ka ua haʻahaʻa ma ka hapa nui o ka ʻākau o koʻu ʻāina, pehea e hoʻonui hou ai a hoʻohana i nā polymers superabsorbent he hana koʻikoʻi e kū nei i nā ʻepekema a me nā ʻenehana. I ka wā o ka hoʻokō ʻana i ka Western Development Strategy, i ka hana o ka hoʻomaikaʻi ʻana i ka lepo, e hoʻomohala ikaika a hoʻohana i nā hana hana he nui o nā polymers super absorbent, nona nā pono pili waiwai a me nā pono waiwai. Ua uhi ʻia ʻo Zhuhai Demi Chemicals ma kahi o 30,000 mau mika square. He mea kūikawā ia i ka noiʻi a me ka hoʻomohala ʻana a me ka hana ʻana i nā huahana e pili ana i ka super absorbent material (SAP). ʻO ia ka ʻoihana kūloko mua i hana i nā resins super absorbent e hoʻohui i ka noiʻi ʻepekema, hana, kūʻai aku, a me nā lawelawe ʻenehana. ʻoihana ʻenehana kiʻekiʻe. Loaʻa i ka hui nā kuleana waiwai naʻauao kūʻokoʻa, nā noiʻi ikaika a me nā hiki ke hoʻomohala, a hoʻolaha mau i nā huahana hou. Hoʻokomo ʻia ka papahana i loko o ka "palapala lama" aupuni a ua hoʻomaikaʻi ʻia i nā manawa he nui e nā aupuni aupuni, panalāʻau a me nā aupuni kūloko.
Wahi noi
1. Nā noi ma ka mahiʻai a me ka mahiʻai
ʻO ka resin absorbent super i hoʻohana ʻia i ka mahiʻai a me ka horticulture ua kapa ʻia ʻo ia ka mea mālama wai a me ka mea hoʻonaninani lepo. ʻO koʻu ʻāina he ʻāina me ka hapa nui o ka wai ma ka honua. No laila, ʻoi aku ka nui o ka hoʻohana ʻana i nā mea mālama wai. I kēia manawa, ʻoi aku ma mua o ʻumikūmālua mau hale noiʻi home i hoʻomohala i nā huahana resin super absorbent no ka palaoa, pulupulu, ʻaila, a me ke kō. , Paka, huaʻai, nā mea kanu, nā ululāʻau a me nā mea kanu ʻē aʻe ma mua o 60 mau ʻano mea kanu, ʻoi aku ka nui o ka wahi hoʻolaha ma mua o 70,000 mau ʻeka, a me ka hoʻohana ʻana i ka resin super absorbent ma Northwest, Inner Mongolia a me nā wahi ʻē aʻe no ka hoʻoulu ʻana i ke one nui. ʻO nā resins super absorbent i hoʻohana ʻia ma kēia ʻano, ʻo ia ka starch grafted acrylate polymer cross-linked products and acrylamide-acrylate copolymer cross-linked products, kahi i hoʻololi ʻia ai ka paʻakai mai ke ʻano sodium a i ke ʻano potassium. ʻO nā ʻano hana nui i hoʻohana ʻia, ʻo ia ke kāʻei ʻana i nā hua, ka pipiʻi ʻana, ka hoʻopili ʻana i ka lua, a i ʻole ka hoʻoinu ʻana i nā aʻa mea kanu ma hope o ka hui ʻana me ka wai e hana i kahi paʻi. I ka manawa like, hiki ke hoʻohana ʻia ka resin super absorbent e ʻaʻahu i ka fertilizer a laila fertilize, i mea e hāʻawi ai i ka pāʻani piha i ka helu hoʻohana ʻana o ka fertilizer a pale i ka ʻōpala a me ka pollution. Hoʻohana pū nā ʻāina ʻē i ka resin super absorbent ma ke ʻano he mea hoʻopihapiha mālama hou no nā huaʻai, nā mea kanu a me nā meaʻai.
2. Hoʻohana nui ʻia nā noi i ka lāʻau lapaʻau a me ka hoʻomaʻemaʻe e like me nā napkins sanitary, nā diapers pēpē, nā napkins, nā ʻeke hau hau kino; nā mea ʻala e like me ka gel no ka hoʻohana ʻana i kēlā me kēia lā e hoʻoponopono i ka lewa. Hoʻohana ʻia ma ke ʻano he lāʻau lapaʻau kumu no ka ʻaila, kaʻaila, liniments, cataplasms, a me nā mea ʻē aʻe, aia nā hana o ka moisturizing, thickening, infiltration ʻili a me ka gelation. Hiki ke hana ʻia i mea lawe akamai e hoʻomalu i ka nui o ka lāʻau i hoʻokuʻu ʻia, ka manawa hoʻokuʻu, a me ka hoʻokuʻu wahi.
3. Hoʻohana ma ka ʻoihana
E hoʻohana i ka hana o ka super absorbent resin e hoʻoheheʻe i ka wai i ka wela kiʻekiʻe a hoʻokuʻu i ka wai ma kahi haʻahaʻa haʻahaʻa e hana ai i ka ʻoihana moisture-proof agent. I nā hana hoʻolaʻa aila ʻaila, ʻoi aku hoʻi i nā ʻaila ʻaila kahiko, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i nā wai wai polyacrylamide kaumaha ultra-high no ka neʻe ʻana o ka aila. Hiki ke hoʻohana ʻia no ka dehydration o nā mea hoʻoheheʻe organik, ʻoi aku hoʻi no nā solvents organik me ka polarity haʻahaʻa. Aia kekahi mau mea hoʻomānoanoa ʻoihana, nā pena e hoʻoheheʻe ʻia i ka wai, etc.
4.Application i ka hana
ʻO ka mea wikiwiki i hoʻohana ʻia i nā papahana mālama wai he resin super absorbent, ka mea i hoʻohana nui ʻia no ka hoʻopili ʻana i nā tunnels dam i nā kau wai, a me ka hoʻopili ʻana i ka wai no nā hui prefabricated o nā basements, tunnels a me nā subways; hoʻohana ʻia no ka hoʻomaʻemaʻe ʻana i ke kaona a me nā papahana dredging Ua hoʻopaʻa ʻia ka lepo e hoʻomaʻamaʻa i ka ʻeli a me ka lawe ʻana.
