He mea ʻona ʻo PolyDADMAC: Wehe i kāna mea pohihihi

PolyDADMAC, he mea paʻakikī a pohihihi hoʻi ka inoa kemika, he ʻāpana koʻikoʻi o ko mākou ola i kēlā me kēia lā. Ma ke ʻano he ʻelele o nā kemika polymer, hoʻohana nui ʻia ʻo PolyDADMAC i nā kula he nui. Eia naʻe, maopopo anei iā ʻoe kona waiwai kemika, ke ʻano o ka huahana, a me nā mea ʻona? A laila, e hāʻawi kēia ʻatikala iā ʻoe i kahi ʻike hohonu o PolyDADMAC.

ʻO nā waiwai kemika o PolyDADMAC e hoʻoholo i kāna mau waiwai kūʻokoʻa. Ma ke ʻano he polyelectrolyte cationic ikaika, ua hoʻolako ʻia ʻo PolyDADMAC ma ke ʻano he wai ʻoniʻoni ʻoniʻoni a i ʻole nā ​​​​momi keʻokeʻo. ʻO kāna mau mea palekana a me nā mea ʻawaʻawa ʻole e hoʻohana nui ʻia i nā kula e like me ka mālama wai, nā textiles, ka hana pepa, a me nā māla aila. Hoʻohui, hiki ke hoʻoheheʻe ʻia ka PolyDADMAC i ka wai, ʻaʻole hiki ke puhi ʻia, he cohesion ikaika, kūpaʻa hydrolytic maikaʻi, ʻaʻole pili i nā hoʻololi pH, a loaʻa nā waiwai maikaʻi e like me ke kūpaʻa chlorine. Hoʻohana maʻamau ia ma ke ʻano he flocculant a hoʻohana ʻia i kekahi manawa me nā algaecides. Ua hōʻike ʻia he hopena synergistic ka PDMDAAC me WSCP a me ka poly-2-hydroxypropyl dimethylammonium chloride.

Pehea e komo ai ka PolyDADMAC? He ikaika ka PolyDADMAC a hoʻokani i nā hana like ʻole ma nā kahua like ʻole. Ma ke ʻano o ka mālama wai, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he cationic flocculant a me ka coagulant. Ma o ka adsorption a me ka bridging, hiki iā ia ke wehe pono i nā mea paʻa i hoʻokuʻu ʻia a me nā haumia i loko o ka wai a hoʻomaikaʻi i ka maikaʻi o ka wai. I ka ʻoihana textile, PolyDADMAC, ma ke ʻano he formaldehyde-free color-fixing agent, hiki ke hoʻomaikaʻi i ka hopena hoʻoponopono kala o nā kala a hana i nā textiles i ʻulaʻula a kū i ka mae. Ma ke kaʻina hana pepa, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he anionic garbage capture agent a me AKD curing accelerator, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka pepa a hōʻemi i nā kumukūʻai hana. Eia kekahi, i ka ʻoihana ʻaila hinu, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he pālolo palolo no ka wili ʻana a me ka hoʻololi ʻana i ka cationic fracturing acid i loko o ka wai e hoʻomaikaʻi ai i ka hoʻihoʻi ʻana i ka māla aila.

Eia naʻe, ʻaʻole ʻo PolyDADMAC kahi pōkā kālā. ʻOiai he nui nā waiwai maikaʻi a me nā wahi noi, pono ʻoe e hoʻolohe i nā pilikia palekana i ka wā e hoʻohana ai. No ka laʻana, pono e pale ʻia ka pili pono ʻana me ka ʻili a me nā maka i ka wā e hoʻohana ai i mea e pale ai i ka huhū. Ma luna o kēlā, pono e hoʻopaʻa ʻia a mālama ʻia ma hope o ka hoʻohana ʻana e pale aku i ka hoʻopili ʻana me nā oxidants ikaika a mālama ʻia i kahi maloʻo a maloʻo. ʻOiai ʻaʻole ʻona ʻo PolyDADMAC, pono ʻoe e hana me ka akahele a hahai i nā lula palekana a me nā kaʻina hana.

I ka hōʻuluʻulu ʻana, hoʻohana nui ʻia ʻo PolyDADMAC, ma ke ʻano he polymer chemical, i nā kula he nui. ʻO kāna mau waiwai kemika kūʻokoʻa a me kāna hana maikaʻi loa e lilo ia i koho kūpono no ka mālama wai, textiles, pepa, a me nā māla aila. Eia nō naʻe, pono ʻoe e makaʻala i nā pilikia palekana i ka wā e hoʻohana ai a hahai i nā lula pili a me nā kaʻina hana. Ma ka hōʻoia ʻana i ka palekana a me ka hoʻohana kūpono o PolyDADMAC hiki iā mākou ke ʻike piha i kona hiki a lawe mai i ka ʻoluʻolu a me nā pōmaikaʻi i ko mākou ola a me kā mākou hana.
