Pehea e koho ai i ka kānana

1. Ma ka kānana

E like me ka manaʻo o ka inoa, hoʻohana ʻia nā kānana no ke kānana ʻana i nā wai a me nā kinoea a me kekahi mau wai.ʻO kāna hana nui ka kānana, i mea e hoʻokō ai i ke kumu o nā mea hoʻohana.

2. Ma ka hoʻokaʻawale ʻana o nā kānana

Hoʻokaʻawale nui ʻia nā kānana i ʻelua mau ʻāpana e like me kā lākou koi pololei.

1. kānana coarse, ʻike ʻia hoʻi he kānana mua.ʻO ka ʻokoʻa nui, ʻo kā lākou kānana pololei ʻoi aku ka nui ma mua o 100 microns (100um a 10mm…).;

2. kānana pololei, i ʻike ʻia he kānana maikaʻi.ʻO ka ʻokoʻa nui, ʻo kā lākou kānana pololei ʻana ma lalo o 100 microns (100um ~ 0.22um).

Wahi a nā koi waiwai, ua māhele ʻia ka kānana i ʻekolu mau ʻāpana:

1. mea hao kalapona (mea maʻamau, e like me Q235., A3, 20 #, a me nā mea'ē aʻe), i hoʻohana nuiʻia no nā wai corrosive a me nā kinoea a pēlā aku.ʻOiaʻiʻo, ma ke ʻano he kānana no nā ʻāpana palupalu.Hana ʻia ia me ke kila kila.

2. mea kila kuhiliʻole (e like me 304, 316, etc.), hoʻohana nui ʻia no ka media corrosive.ʻO ka manaʻo e hiki ke ʻae ʻia kēia mau mea.Hana ʻia ka mea kānana me ke kila kila, metala titanium a i ʻole PP.

3. Hoʻohana nui ʻia nā mea PP (e like me ka polypropylene, polytetrafluoro, me ka lining fluorine a i ʻole ka lining PO, etc.) i nā huahana kemika e like me ka waikawa, ka alkali, ka paʻakai a pēlā aku.ʻO ke kumu kānana maʻamau he polypropylene.

E like me ke koi koi, ua māhele ʻia ka kānana i ʻekolu mau ʻāpana:

1. puʻe haʻahaʻa: 0 ~ 1.0MPa.

2. puʻe waena: 1.6MPa i 2.5MPa.

3. kaomi kiʻekiʻe: 2.5MPa i 11.0MPa.
