E like me kā mākou e ʻike ai ʻo ka ʻāpana kūpono o ka mea hoʻomaʻemaʻe wai ʻo ia kāna mea kānana.
I kēia lā, ua hoʻokaʻawale mākou i nā mea kānana hoʻomaʻemaʻe wai maʻamau a me kā lākou mau hana ma ka mākeke no kāu kuhikuhi wale nō.
Aia ka ◆ʻĀpana kānana osmosis (RO)., ◆Nanofiltration membrane (NF) mea kānana, ◆kānana seramika, ◆ʻĀpana kānana resin, ◆PP pulupulu kānanar, ◆Kaona Ho'opio Granular, ◆ʻO UDF a i ʻole GAC Carbon Activated, ◆ʻEmu kānana Rod Carbon (CTO), ◆ʻElemu Kānana Fiber Carbon.
◆PP pulupulu kānana
Hana ʻia ka mea kānana pulupulu PP me ka polypropylene, ʻaʻole i ʻike ʻia e ka hapa nui o nā kānaka, akā ʻo PP pulup (ʻaʻole PP pulupulu kānana element) e hoʻohana ana i ka polypropylene ma ke ʻano he mea hoʻohana nui ʻia i ke ola o kēlā me kēia lā. ʻO ka hoʻopiha maʻamau o nā uluna a mākou e hoʻohana ai ʻo ka pulupulu PP i hana ʻia me ka polypropylene. I ko mākou hele ʻana i AliExpress e koho i nā mea pāʻani plush, nui nā mea hoʻopihapiha i hōʻike ʻia i nā kikoʻī o ka huahana me ka pulupulu pēpē a me ka pulupulu hollow. ʻOiaʻiʻo, pili lākou a pau i ka pulupulu PP i hana ʻia me ka polypropylene. Ke noʻonoʻo nei ʻoe, kamaʻāina ʻoe i ka polypropylene? ʻAe, ua poina iaʻu e haʻi aku ʻo ka polypropylene ponoʻī ʻaʻole ia he mea ʻawaʻawa, no laila hiki ke hoʻohana ʻia ma ke ʻano he kumu waiwai no nā mea kānana. ʻOiai ua hana ʻia nā mea kānana PP pulupulu a me ka pulupulu PP e like me ka hoʻopiha ʻana i nā mea hana i polypropylene, aia nō nā ʻokoʻa nui ma waena o nā mea ʻelua. ʻO ka mea kānana pulupulu PP e pili ana i ka hoʻoheheʻe polypropylene he mea kānana puhi. E pili ana i ka mea kānana hoʻoheheʻe ʻia, ʻo ka ʻōlelo kumu: ua hana ʻia ka mea kānana melt-blown me nā ʻāpana polypropylene non-toxic a me ka ʻala ʻole, i hoʻoheheʻe ʻia e ka hoʻomehana ʻana, ka wili, ke kaha kiʻi, a me ka hana ʻana. Hana ʻia ka mea kānana tubular. ʻO ka pololei o ka kānana ʻana o ka mea kānana pulupulu PP mai 0.5μm (micron) a i 20μm. ʻO ke anawaena o ka lauoho kanaka mai 0.017 a 0.18 mm (17 a 18 microns, mai Wikipedia ka ʻikepili).
ʻO nā mea kānana pulupulu PP i hoʻohana ʻia i nā mea hoʻomaʻemaʻe wai, ʻo ia nā mea kānana pulupulu PP maʻamau a me nā mea kānana pulupulu PP kiʻekiʻe, i hoʻokomo pinepine ʻia i ka papa mua a me ke kolu o nā mea kānana. ʻO ka polypropylene melt-blown i hōʻike ʻia e kekahi poʻe kālepa ma ka ʻaoʻao hoʻolaha e like me ka huahana kiʻekiʻe loa, akā he mea kānana PP pulupulu maoli.
I koʻu hoʻomaopopo ʻana, ʻo ka ʻokoʻa ma waena o ka mea kānana PP pulupulu kiʻekiʻe kiʻekiʻe a me ka mea kānana pulupulu PP maʻamau ka mea nui i ka nui o ka pore. ʻOi aku ka liʻiliʻi o ka pore o ka pulupulu PP kiʻekiʻe ma mua o ka pulupulu PP maʻamau, hiki ke kānana i nā haumia liʻiliʻi. Ke kahe ka wai inu ma ka papa mua o ka pulupulu PP, ua like ia me ke kahe ʻana i loko o ka pale, kahi e pahele ai i nā ʻāpana nui o ka lepo a me nā mea haumia ʻē aʻe. Ke kahe ka wai ma ka papa ʻekolu o ka pulupulu PP kiʻekiʻe, e kānana ia i nā mea ʻoi aku ka maikaʻi ma mua o ka papa mua. (No ka pololei o ka kānana, ʻo ka ʻikepili hoʻolaha o nā mea kālepa i hiki ke loaʻa ma Jingdong ʻo 5μm. Inā helu ʻia ka filtration pololei o 5μm, mamao loa ia e kānana i nā maʻi bacteria a me nā maʻi.
◆Kapona Hoʻoikaika ʻia
Manaʻo wau ʻaʻole malihini ka poʻe a pau i ka carbon activated. Loaʻa nā waiwai adsorption ikaika.
Hoʻohana nui ʻia ke kalapona hoʻōla ma muli o kona mau hiʻohiʻona. Nui ka poʻe i hoʻāla i nā ʻeke kalapona i loko o kā lākou kaʻa no ka wehe ʻana i nā mea ʻala, a ʻo kekahi poʻe i loko o nā hale i hoʻoponopono hou ʻia e hoʻokomo pū i kekahi mau ʻeke kalapona hoʻāla e wehe i ka formaldehyde.
ʻIke pinepine mākou i ka nui o nā mea hoʻomaʻemaʻe wai e hoʻohana i ke kalapona hoʻāla ʻia ma ke ʻano he kānana i loko o ka pepa hoʻomaʻemaʻe wai, e komo pū ana me ka carbon activated granular, carbon fiber filter element, carbon rod filter element, etc. No laila pehea ka ʻokoʻa?
ʻO ka kānana kalapona i hoʻohana mau ʻia i nā mea hoʻomaʻemaʻe wai he ʻano kalapona i hoʻohana ʻia (UDF/GAC). Eia kekahi, ʻo ka mea nui o ka carbon activated granular hiki ke lilo i ʻāpana apricot, nā pūpū wōnati, a me nā pūpū huaʻai a i ʻole ka lanahu e like me ka anthracite. Ua hana ʻia ke kalapona i hana ʻia ma ka hoʻāla ʻana i kēia mau mea ma ke ʻano he nui nā pores liʻiliʻi, akā ʻaʻole kūlike ka nui o kēia mau pores. Wahi a ke anawaena, ua māhele ʻia lākou i nā micropores ma lalo o 2nm, macropores ma luna o 50nm, a me nā mesopores i ka waena (I kapa ʻia hoʻi ka puka hoʻololi). Hiki i kekahi pores ke hiki i 1000nm.
◆Kānana Rod Carbon (CTO)
ʻO nā mea kānana koʻokoʻo kalapona i hoʻohana pinepine ʻia ʻo ia ka carbon activated compressed a me ka carbon activated sintered (ua hoʻokomo pū ʻia ka carbon activated extruded i CTO, akā ma muli o ka liʻiliʻi loa o ka hiki ʻana o ka adsorption i ka wā o ke kaʻina hana). Hoʻokumu ʻia ke kalapona hoʻāla ʻia ma o ka hui ʻana i ka pauka kalapona hoʻōla a me ka mea hoʻopaʻa wai inorganic ma lalo o ke kaomi kiʻekiʻe.
Hoʻopili ʻia ke kalapona hoʻōla ʻia ma ka wela kiʻekiʻe ma hope o ka hui ʻana i ka pauka kalapona hoʻōla a me ka polymer hot-melt pore-forming material. No ka mea, ʻo ka polymer wela hoʻoheheʻe pore-forming material i hoʻohana ʻia i ka carbon activated sintered e hana pū ana i nā pores i nā wela kiʻekiʻe, a ʻaʻole hiki i ka mea hoʻopaʻa wai inorganic i loko o ke kalapona hoʻāla ʻia ʻaʻole hiki ke hana i nā pores ma lalo o ke kaomi kiʻekiʻe, ʻoi aku ka maikaʻi o ka kānana a me nā hopena decolorization ma mua o ke kalapona hoʻōla ʻia. E like me ke kalapona i ho'ā 'ia
◆Kāna Fiber Carbon
ʻO ka mea kānana fiber carbon e pili ana i kahi mea kānana carbon fiber filter element (ACF). ʻAʻole ia he pauka maʻamau a ʻano granular paha o ka kalapona hoʻāla ʻia, akā he fibrous. ʻO ka fiber he filament mau a hoʻopau paha. Hoʻokumu ʻia ka pulupulu kalapona i hoʻāla ʻia me kahi mea i haku ʻia me ke kilika paʻa kalapona hoʻōla. Ua uhi ʻia kēia mau filament me ka nui o nā micropores a me nā mesopores. ʻAʻole like me ka carbon activated granular, ʻaʻohe ona macropores a ʻano like. Ke kahe ka wai i loko o ka activated carbon fibers, ʻoi aku ka maʻalahi o nā pores ma nā filament maikaʻi e hoʻopili me nā mea i loko o ka wai ma mua o nā pores i loko o ka carbon activated granular me ka leo like, a ʻoi aku ka wikiwiki o ka adsorption ma mua o ka granular activated carbon. No ka mea, ʻoi aku ka nui o ka ʻili o ka ʻili i ka wai ma mua o ka carbon activated granular, a i ka wā e kahe ai ka wai, ʻo ka hapa nui o nā pores kūloko o ka granular activated carbon ʻaʻole i pili me nā haumia i loko o ka wai, no laila ma lalo o nā ʻano like, hiki i ka nui like o ka carbon activated fiber ke komo i nā mea (e like me hiki ke hōʻiliʻili i ka carcinogenic trichlorethylene (TCE) a me nā maʻi Escherich i loko o ke kino o ke kanaka. kūlana). ʻOiaʻiʻo, loaʻa nā hemahema o ka pulupulu kalapona: kiʻekiʻe ke kumukūʻai, a ʻaʻohe ʻikepili i loaʻa e hōʻike i ka hiki ke hoʻopau ke kalapona i hoʻāla ʻia.
I ka hana o ka intercepting nui particles, activated carbon fiber filter element>activated carbon rod>granular activated carbon.
