He aha nā hana kikoʻī a nā surfactants e pāʻani ai i nā hana hoʻomaʻemaʻe like ʻole?

1. Noi ma Chelating Cleaning

Hoʻohana ʻia nā mea hana chelating, i ʻike ʻia ʻo nā mea paʻakikī a i ʻole nā ​​ligands, i ka paʻakikī (coordination) a i ʻole chelation o nā ʻano chelating like ʻole (me nā mea hoʻohui paʻakikī) me nā ion scaling e hoʻohua i nā mea paʻakikī (hui hui) no ka hoʻomaʻemaʻe ʻana.

ʻO nā mea hoʻoheheʻeHoʻohui pinepine ʻia i ka hoʻomaʻemaʻe chelating agent e hāpai i ke kaʻina hana hoʻomaʻemaʻe. ʻO nā mea hana paʻakikī inorganic i hoʻohana mau ʻia he sodium tripolyphosphate, ʻoiai ʻo nā mea hana chelating organik i hoʻohana mau ʻia he ethylenediaminetetraacetic acid (EDTA) a me ka waikawa nitrilotriacetic (NTA). ʻAʻole hoʻohana wale ʻia ka hoʻomaʻemaʻe ʻana o Chelating no ka hoʻomaʻemaʻe ʻana i ka ʻōnaehana wai akā ua ʻike pū kekahi i ka ulu nui ʻana i ka hoʻomaʻemaʻe ʻana i nā unahi paʻakikī. Ma muli o kona hiki ke paʻakikī a chelate i nā ion metala i nā unahi paʻakikī e hoʻoheheʻe, hāʻawi ia i ka hana hoʻomaʻemaʻe kiʻekiʻe.

2. Hoʻohana ʻia i ka ʻaila nui a me ka hoʻomaʻemaʻe coke

I loko o nā mea kanu hoʻomaʻemaʻe ʻaila a me nā mea kanu petrochemical, ʻeha pinepine nā mea hoʻololi wela a me nā paipu i ka hoʻoheheʻe ʻana i ka aila kaumaha a me ka waiho ʻana o ka coke, pono e hoʻomaʻemaʻe pinepine. ʻO ka hoʻohana ʻana i nā mea hoʻoheheʻe organik he mea ʻawaʻawa, ʻā a pahū, ʻoiai ʻaʻole pono nā ʻano hoʻomaʻemaʻe alkaline maʻamau i ka hoʻoheheʻe ʻana i ka aila kaumaha a me ka coke.

I kēia manawa, hoʻokumu ʻia nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe aila kaumaha ma ka ʻāina a me ka honua ma luna o nā surfactant composite, i hui pū ʻia me nā mea hoʻoheheʻe nonionic a me anionic, me nā mea hana inorganic a me nā mea alkaline. ʻAʻole hoʻopuka wale nā ​​surfactants composite i nā hopena e like me ka pulu, ke komo ʻana, emulsification, dispersion, solubilization, a me ka huʻihuʻi akā loaʻa pū kekahi i ka hiki ke komo i ka FeS₂. ʻO ka maʻamau, pono ka hoʻomehana ʻana ma luna o 80 ° C no ka hoʻomaʻemaʻe.

3. Noi i loko o ka wai hooluolu Biocides

Ke loaʻa ka microbial slime i nā ʻōnaehana wai hoʻoluʻu, hoʻohana ʻia nā biocides non-oxidizing, me nā surfactants nonionic haʻahaʻa haʻahaʻa e like me nā dispersants a me nā penetrant, e hoʻonui i ka hana o nā mea hana a hoʻoikaika i ko lākou komo ʻana i loko o nā cell a me ka papa mucus o nā fungi.

Hoʻohui ʻia, hoʻohana nui ʻia nā biocides paʻakai ammonium quaternary. ʻO kēia kekahi mau surfactant cationic, me ka mea maʻamau ʻo benzalkonium chloride a me benzyldimethylammonium chloride. Hāʻawi lākou i ka mana biocidal ikaika, maʻalahi o ka hoʻohana, haʻahaʻa haʻahaʻa, a me ke kumu kūʻai haʻahaʻa. Ma waho aʻe o kā lākou hana o ka wehe ʻana i ka slime a me ka wehe ʻana i nā mea ʻala mai ka wai, loaʻa iā lākou nā hopena pale ʻino.

Eia kekahi, ʻo nā biocides i haku ʻia me nā paʻakai ammonium quaternary a me ka methylene dithiocyanate ʻaʻole wale nā ​​hopena ākea ākea a me ka synergistic biocidal akā pale pū i ka ulu ʻana o ka slime.
