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, ◆Kalapona 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 ka poʻe, akā ʻo PP pulup (ʻaʻole PP pulupulu kānana element) me ka polypropylene e like me ka mea maka i 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.ʻO kaʻoiaʻiʻo, pili lākou a pau i ka pulupulu PP i hana ʻia me ka polypropylene.Ke noʻonoʻo nei ʻoe, kamaʻāina ʻoe i ka polypropylene?ʻAe, poina iaʻu e haʻi aku i ka polypropylene ponoʻī ʻaʻole ia he mea ʻawaʻawa, no laila hiki ke hoʻohana ʻia ma ke ʻano he mea maka 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 i hana ʻia me ka 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 milo, 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 kahi 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 nui o 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 ma ka pale, e pahele mau ana i nā ʻāpana nui o ka sediment 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 kūʻai aku i hiki ke loaʻa ma Jingdong he 5μm. Inā helu ʻia ka filtration pololei o 5μm, mamao loa ia e kānana i ka 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 ʻano.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 hoʻā e wehe i ka formaldehyde.
ʻIke pinepine mākou i ka hoʻohana ʻana o nā mea hoʻomaʻemaʻe wai i ke kalapona hoʻāla ʻia ma ke ʻano he mea 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 lākou 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, ʻili wōnati, a me nā pūpū hua a i ʻole ka lanahu e like me ka anthracite.Hoʻokumu ʻia ke kalapona hoʻāla ʻia ma ka hoʻāla ʻana i kēia mau mea no ka mea ua hoʻokumu ʻia nā pores liʻiliʻi he nui, akā ʻaʻole like ka māhele 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 ma 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 adsorption i ka wā o ke kaʻina hana).Hoʻokumu ʻia ke kalapona hoʻoikaika ʻia e ka hui ʻana i ka pauka carbon activated a me ka mea hoʻopaʻa wai inorganic ma lalo o ke kaomi kiʻekiʻe.
Hoʻopaʻa ʻia ke kalapona hoʻā i hoʻopaʻa 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 i nā pores i nā wela kiʻekiʻe, a ʻo ka mea hoʻopili wai inorganic i loko o ka carbon activated compressed 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 ka compressed activated. ʻoi aku ka maikaʻi o ke kalapona.E like me ke kalapona hoʻā i hoʻopaʻa ʻia
◆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 ka siliki 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 ma o nā filament carbon activated, ʻoi aku ka maʻalahi o nā pores ma nā filament maikaʻi e pili 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 wikiwiki ma mua o ka. kalapona hoʻōla granular.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 granular activated carbon ʻaʻole i hoʻopili ʻia me nā haumia i loko o ka wai, no laila ma lalo o nā kūlana like. ʻO ka nui o ka fiber carbon activated hiki ke hoʻopaʻa i nā mea (e like me Hiki ke hōʻiliʻili i ka carcinogenic trichlorethylene (TCE) a me Escherichia coli i hiki ke hoʻoulu i nā maʻi ʻōpū a i ʻole nā maʻi o ke kino o ke kanaka ma lalo o kekahi mau 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.
