He mea ʻawahia anei ʻo PolyDADMAC: E wehe i kona mea pohihihi?

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

ʻO nā waiwai kemika o PolyDADMAC e hoʻoholo i kona mau waiwai kū hoʻokahi. Ma ke ʻano he polyelectrolyte cationic ikaika, hoʻolako ʻia ʻo PolyDADMAC ma ke ʻano he wai viscous ʻaʻohe kala a melemele māmā, a i ʻole he mau momi keʻokeʻo i kekahi manawa. ʻO kona mau waiwai palekana a ʻaʻohe ʻawahia e hoʻohana nui ʻia ai i nā kahua e like me ka mālama ʻana i ka wai, nā lole, ka hana pepa, a me nā kahua aila. Eia kekahi, maʻalahi ka hoʻoheheʻe ʻia ʻana o PolyDADMAC i ka wai, ʻaʻole hiki ke lapalapa, he cohesion ikaika, kūpaʻa hydrolytic maikaʻi, ʻaʻole ia e pili i nā loli pH, a he mau waiwai maikaʻi loa e like me ke kū'ē ʻana i ka chlorine. Hoʻohana pinepine ʻia ia ma ke ʻano he flocculant a i kekahi manawa ua hoʻohui ʻia me nā algaecides. Ua hōʻike ʻia he hopena synergistic ko PDMDAAC me WSCP a me poly-2-hydroxypropyl dimethylammonium chloride.

Pehea e hoʻohana ʻia ai ʻo PolyDADMAC?

He ikaika ʻo PolyDADMAC a he ʻano hana like ʻole ia ma nā ʻano like ʻole. Ma ke ʻano kikoʻī, ma ke kahua o ka mālama ʻana i ka wai, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he flocculant cationic a me ka coagulant. Ma o ka adsorption a me ke bridging, hiki iā ia ke wehe pono i nā mea paʻa a me nā haumia i loko o ka wai a hoʻomaikaʻi i ka maikaʻi o ka wai. Ma ka ʻoihana lole, hiki iā PolyDADMAC, ma ke ʻano he formaldehyde-free color-fixing agent, ke hoʻomaikaʻi i ka hopena hoʻopaʻa kala o nā dyes a hana i nā lole i ʻālohilohi a kū i ka mae. Ma ke kaʻina hana pepa, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he anionic garbage capture a me AKD curing accelerator, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka pepa a hoʻemi i nā kumukūʻai hana. Eia kekahi, ma ka ʻoihana kahua aila, hoʻohana ʻia ʻo PolyDADMAC ma ke ʻano he mea hoʻopaʻa lepo no ka ʻeli ʻana a me kahi mea hoʻololi cationic acid fracturing i ka injection wai e hoʻomaikaʻi i ka hoʻōla ʻana o ke kahua aila.

Eia nō naʻe, ʻaʻole ʻo PolyDADMAC he mea hoʻopunipuni. ʻOiai he nui nā waiwai maikaʻi a me nā wahi noi, pono ʻoe e makaʻala i nā pilikia palekana i ka wā e hoʻohana ai. No ka laʻana, pono e pale ʻia ka pili pololei ʻana me ka ʻili a me nā maka i ka wā e hoʻohana ai e pale aku 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 pili ʻana me nā oxidants ikaika a mālama ʻia i kahi maloʻo a me kahi anuanu. ʻOiai ʻaʻole ʻawahia ka PolyDADMAC, pono ʻoe e hoʻohana me ke akahele a hahai i nā lula palekana a me nā kaʻina hana.

I ka hōʻuluʻulu ʻana, ʻo PolyDADMAC, ma ke ʻano he kemika polymer, ua hoʻohana nui ʻia ma nā ʻano he nui. ʻO kona mau waiwai kemika kū hoʻokahi a me ka hana maikaʻi loa e lilo ia i koho kūpono no ka mālama ʻana i ka wai, nā lole, ka pepa, a me nā kahua aila. Eia nō naʻe, pono ʻoe e hoʻolohe 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 hoʻohana palekana a kūpono hoʻi o PolyDADMAC hiki iā mākou ke hoʻomaopopo piha i kona hiki a lawe mai i nā mea hou aku a me nā pono i ko mākou ola a me ka hana.
