ʻOkoʻa ma waena o ka kānana ʻili a me ka kānana hohonu

Hoʻohana nui ʻia nā mea pale no ka kānana ʻili a hoʻohana ʻia nā mea manaʻo no ka kānana hohonu. ʻO nā ʻokoʻa penei:

1. Hoʻopili pololei ka mea pale (nylon monofilament, metala monofilament) i nā haumia i loko o ka kānana ma ka ʻili o ka mea. ʻO nā pōmaikaʻi, hiki ke hoʻomaʻemaʻe pinepine ʻia ka hale monofilament a haʻahaʻa ke kumukūʻai hoʻohana; Akā ʻo ka hemahema ʻo ke ʻano kānana ili, maʻalahi ke kumu i ka blockage ʻili o ka ʻeke kānana. ʻO kēia ʻano huahana ka mea kūpono loa no nā manawa kānana koʻikoʻi me ka haʻahaʻa haʻahaʻa, a ʻo ka filtration precision ʻo 25-1200 μm.

2. Felt mea (needle punched lole, solution blown non-woven fabric) he mea ma'amau ka hohonu ekolu-dimensional kānana, i 'ike 'ia e ka wehe 'ana i ka pulupulu a me ka porosity ki'eki'e, e ho'onui i ka hiki o ka haumia. ʻO kēia ʻano mea fiber no ke ʻano interception hui, ʻo ia hoʻi, ʻoi aku ka nui o nā mea haumia ma luna o ka ʻili o ka fiber, ʻoiai ua paʻa nā ʻāpana maikaʻi i ka papa hohonu o ka mea kānana, no laila ʻoi aku ka maikaʻi o ka kānana ʻana, ʻoi aku ka maikaʻi o ka hoʻomaʻamaʻa ʻana i ka wela wela, ʻo ia hoʻi, ka hoʻohana ʻana i ka ʻenehana sintering koke, hiki ke pale pono i ka hopena o ka wai ma muli o ka nalowale ʻana o ka wai; Hoʻokuʻu ʻia ka mea i manaʻo ʻia a ʻo ka filtration pololei ʻo 1-200 μm.

ʻO nā mea waiwai nui o ka kānana felt penei:

ʻO Polyester - ka fiber kānana maʻamau i hoʻohana pinepine ʻia, kūpaʻa kemika maikaʻi, ka mahana hana ma lalo o 170-190 ℃

Hoʻohana ʻia ka polypropylene no ka kānana wai i ka ʻoihana kemika. Loaʻa iā ia ka maikaʻi o ka waikawa a me ka alkali. ʻO ka mahana hana ma lalo o 100-110 ℃

Wool - maikaʻi anti solvent hana, akā ʻaʻole kūpono no ka anti acid, kānana alkali

He kūpaʻa kemika maikaʻi ʻo Nilong (koe wale ka pale ʻana o ka waikawa), a ʻoi aku ka mahana o kāna hana ma mua o 170-190 ℃

Loaʻa i ka Fluoride ka hana maikaʻi loa o ka pale wela a me ke kūpaʻa kemika, a ʻoi aku ka mahana o ka hana ma mua o 250-270 ℃

Hoʻohālikelike i nā pono a me nā pōʻino ma waena o nā mea kānana ili a me nā mea kānana hohonu

Nui nā ʻano mea kānana no nā kānana. E like me ka ulana uea mesh, kānana pepa, metala pepa, sintered kānana mea a me ka manaʻo, etc. Eia naʻe, e like me kona kānana ana, hiki ke maheleia i elua ano, o ka ili o ka ili a me ka hohonu ano.

1. Mea kānana ili
Kapa ʻia ʻo ka mea kānana ʻano o ka ʻili. Aia kona ili i kekahi geometry, micropores like ʻole a i ʻole nā ​​kahawai. Hoʻohana ʻia ia e hopu i ka lepo i loko o ka ʻaila pale. ʻO ka mea kānana ka mea maʻamau a i ʻole ke kānana twill i hana ʻia me ka uea metala, ka lole lole a i ʻole nā ​​​​mea ʻē aʻe. ʻO kāna kumu kānana e like me ka hoʻohana ʻana i ka pale pololei. Aia kona pololei kānana i nā ana geometric o nā micropores a me nā kahawai.

ʻO nā pono o ka mea kānana ʻano ili: hōʻike pololei o ka pololei, ākea ākea o ka noi. Maʻalahi e hoʻomaʻemaʻe, hiki ke hoʻohana hou ʻia, lōʻihi ke ola lawelawe.

ʻO nā pōʻino o ka mea kānana ʻano ili penei: ka liʻiliʻi o ka mea haumia; Ma muli o ka palena o ka ʻenehana hana, ʻoi aku ka pololei ma mua o 10um

2. Mea kānana hohonu
Kāhea ʻia ka mea kānana ʻano hohonu a i ʻole nā ​​mea kānana ʻano kūloko. He mānoanoa ka mea kānana, hiki ke hoʻomaopopo ʻia he superposition o nā kānana ʻano he nui. ʻAʻohe mea maʻamau a ʻaʻohe nui kikoʻī o ka āwaha hohonu. Ke hele ka aila i loko o ka mea kānana, hopu ʻia ka lepo i loko o ka ʻaila a hoʻopili ʻia ma nā hohonu like ʻole o ka mea kānana. No laila e pāʻani i ke kuleana o ka kānana. ʻO ka pepa kānana kahi mea kānana hohonu maʻamau i hoʻohana ʻia i ka ʻōnaehana hydraulic. ʻO ka pololei ma waena o 3 a me 20um.

ʻO nā mea maikaʻi o nā mea kānana ʻano hohonu: ka nui o ka lepo, ka lōʻihi o ka lawelawe ʻana, hiki ke hoʻoneʻe i nā ʻāpana liʻiliʻi ma mua o ka pololei a me ke kāʻei, kānana kiʻekiʻe.

Nā pōʻino o ka mea kānana ʻano hohonu: ʻaʻohe ʻano like ʻole ka nui o ka ʻāpana kānana. ʻAʻole hiki ke mālama pono ʻia ka nui o nā ʻāpana haumia; Aneane hiki ole ke hoomaemae. ʻO ka hapa nui o lākou he mea hoʻopau. Nui ka hoʻohana ʻana.
