He ʻāpana hana koʻikoʻi ka papa kānana o ka mīkini kānana no ka hoʻopau ʻana i ke kaʻina hana kānana. Pono kēlā me kēia lako kānana e koho i kahi papa kānana e kūpono i kāna mau koi hana.

ʻO nā ʻano like ʻole o nā mea hana, ke ʻano like ʻole o ka papa sieve, nā mea hana a me nā ʻano like ʻole o ka mīkini sieve he hopena ko lākou i ka hiki ke kānana, ka pono, ka holo ʻana o ka mīkini a me ke ola o ka pale haʻalulu. E hoʻokō i ka hopena kānana maikaʻi loa i ka papa sieve.

Wahi a ka nui o nā ʻāpana o ka mea e kānana ʻia ana a me nā koi ʻenehana o ka hana kānana, hiki ke puʻunaue ʻia nā papa sieve i nā ʻano penei:
  
1. Pale wehe
    
Ua haku ʻia ka pale koʻokoʻo i kahi hui o nā koʻokoʻo kila i hoʻonohonoho like ʻia a loaʻa i kahi ʻano ʻokiʻoki.
Hoʻonohonoho like ʻia nā koʻokoʻo, a ʻo ka mamao ma waena o nā koʻokoʻo ka nui o nā lua pale. Hoʻohana pinepine ʻia nā pale koʻokoʻo no nā pale paʻa a i ʻole nā ​​​​pale haʻalulu hana kaumaha, a kūpono no ka nānā ʻana i nā mea ʻili nui me nā nui o nā ʻāpana ma mua o 50mm.

2. Pale kuʻi
      
ʻO ka maʻamau, ua kuʻi ʻia nā papa kānana punching mai loko mai o nā lua kānana poepoe, huinahā a ʻehā paha ma nā papa kila me ka mānoanoa o 5-12mm. Ke hoʻohālikelike ʻia me ka papa kānana poepoe a huinahā paha, ʻoi aku ka nui o ka ʻili kānana o ka kānana huinahā, ʻoi aku ka māmā o ke kaumaha a ʻoi aku ka nui o ka huahana. He kūpono ia no ka hana ʻana i nā mea me ka nui o ka makū, akā ʻaʻole maikaʻi ka pololei o ka hoʻokaʻawale ʻana o ka kānana.
  
3. Papa pale ʻupena i ulana ʻia:
    
Ua ulana ʻia ka papa kānana ʻupena me ka uea metala i kaomi ʻia me kahi buckle, a he huinahā a he ʻāpana huinahā paha ke ʻano o ka lua kānana. ʻO kona mau pono: māmā ke kaumaha, wikiwiki ka wehe ʻana; a i ke kaʻina hana kānana, no ka mea he elasticity ko ka uea metala, haʻalulu ia i kahi alapine kiʻekiʻe, i hāʻule ai nā ʻāpana liʻiliʻi i hoʻopili ʻia i ka uea kila, a laila e hoʻomaikaʻi ana i ka pono o ka kānana. He kūpono ia no ka kānana ʻana i nā mea palaoa waena a me nā mea lahilahi. Eia naʻe, he pōkole kona ola.

4. Pale kau
  
Hana ʻia ka papa kānana i hoʻokaʻawale ʻia me ke kila kila e like me ke kaola kānana. ʻEkolu ʻano ʻano: wili ʻia, hoʻopaʻa ʻia a ulana ʻia.
He poepoe ke ʻano o ka ʻāpana kānana o ka papa kānana kānana, a hiki i ka laulā o ke kōpana ke 0.25mm, 0.5mm, 0.75mm, 1mm, 2mm, a pēlā aku.
He kūpono ka papa kānana slotted no ka hoʻohemo ʻana i ka wai, desizing a me ka desliming ma waenakonu o ka palaoa maikaʻi.

5. Pā kānana polyurethane:
      
ʻO ka papa kānana polyurethane kahi ʻano papa kānana elastic polymer, nona ke kūpaʻa maikaʻi loa i ka abrasion, ke kūpaʻa aila, ke kūpaʻa hydrolysis, ke kūpaʻa bacteria, a me ke kūpaʻa ʻelemakule. ʻAʻole hiki i ka papa kānana ke hōʻemi nui i ke kaumaha o nā lako, hoʻemi i ke kumukūʻai o nā lako, hoʻolōʻihi i ke ola lawelawe, akā hoʻemi pū i ka walaʻau. Hoʻohana nui ʻia ia i ka mining, metallurgy, lanahu kalapona, coke, holoi lanahu, petroleum, kemika a me nā ʻoihana ʻē aʻe.
      
ʻO ke ʻano o nā lua i loko o ka papa kānana polyurethane: nā niho kuʻi, nā lua huinahā, nā lua lōʻihi, nā lua poepoe, a me ke ʻano puka. Ka nui o ka māka ʻana o nā mea: 0.1-80mm.

ʻO ka paʻa like ʻana o ka papa kānana i ka wā e kau ʻia ai ma ka pahu kānana he hopena nui ia i ka pono o ka kānana a me ke ola lawelawe o ka ʻili kānana. Ma ke ʻano laulā, hoʻopaʻa ʻia nā pale punching a me nā pale slot me nā wedges lāʻau; nā ʻupena ulana me ke anawaena ʻupena liʻiliʻi a me nā pale punching me ka mānoanoa ma lalo o 6mm e hoʻopaʻa ʻia me nā lou huki; nā ʻupena ulana me ke anawaena ʻupena ʻoi aku ma mua o 9.5mm a ʻoi aku ka mānoanoa. Hoʻopaʻa ʻia ka pale punching 8mm ma ke kaomi ʻana a me nā wili.
