ʻO nā paipu pukaua hana ʻia me ka aluminika, ke kila kila, ke kila kalapona a me ka pepa ala.E like me ka wehe ʻana o ke anawaena, hoʻolālā mākou i ka laulā o ka pā a me nā puka punch i hoʻonohonoho ʻia e ʻoe. A laila ua hoʻopuni ʻia kēia mau papa i loko o kahi spiral a i ʻole pololei a welded e ka argon arc welding.Hoʻopili ʻia ka ʻili o ka paipu kānana perforated e ka electrolytic polishing, galvanization, sandblasting, pickling a me ka passivation.

Me nā mea paʻa a me nā hiʻohiʻona like ʻole, hiki i nā paipu perforated ke kānana i nā wai, paʻa a me ka ea a kānana paha i nā mea like ʻole e hōʻoia i ka maʻemaʻe.ʻO ka hoʻonāwaliwali ʻana o ka walaʻau a me ka hoʻoheheʻe ʻana o ka hale ʻaina kekahi mau hana koʻikoʻi.Me ka maikaʻi o ka waikawa a me ka alkali, ʻo ka sieving tube he huahana kūpono loa no ka kānana ʻana i nā pauka seramika, nā mea aniani, nā mea plastik, nā lepo, nā ʻāpana mineral, nā ʻāpana lāʻau, nā pauka metala, etc.

Ka hoʻohana ʻana i ka paipu perforated:

• E kānana i ka wai a me ka ea, e like me ka wai, ka aila, etc.
• E kānana i nā mea like ʻole a wehe i nā haumia, e like me ka ʻoihana meaʻai, lāʻau lapaʻau, kemika a me ka ʻoihana mālama kaiapuni.
• E like me nā papa hana like ʻole o nā mea kānana.
• E hoʻonāwaliwali i ka walaʻau.
• Hoʻohana ʻia no ka ventila granary.

Nā hiʻohiʻona o ka paipu perforated:

• ʻO nā kuʻekuʻe like a me ke kūpaʻa maikaʻi.
• Poe pololei a pololei.
• ʻili paheʻe.
• Kiʻekiʻe kānana pololei.
• Hiki ke ʻoki i ka walaʻau a me ka ventilate.
• E pale i ka waikawa, alkali, haʻahaʻa a me ke kiʻekiʻe o ka mahana, no laila he lōʻihi ke ola lawelawe.

Nā ʻōlelo kikoʻī o ka paipu perforated:

• Nā mea waiwai: ka pā aluminika, ke kila kila, ka pā kila, ka pā hao, ka pā hao, ka pā kila kalapona, ka pā keleawe.
• Mānoanoa: 0.4–15 mm.
• ʻO ka lōʻihi o ka paipu: 10–6000 mm, a i ʻole e like me ka nui āu e makemake ai.
• ʻO ke anawaena o waho: 6–200 mm.
• ʻO ke ʻano o ka puka pā: puni, rectangular, square, hexagonal, oval, plum blossom, etc.
• Anawaena puka: 3–10 mm.
• Wahi wehe: 23%–69%.
• Ka pololei kānana: 2–2000 μm.
• Kaʻina hana welding: Ka ʻili: electrolytic polishing, galvanization, sandblasting, pickling a me ka passivation.
  • wili wahi a i ʻole wili piha.
  • wili pololei a i ʻole wiliwili spiral.
  • wiliwili argon arc.
• Ka hoʻonohonoho ʻana o ka pahu: ka palena a i ʻole ka palena ʻole.
• Pākuʻi: pepa moisture-proof, pallet, pahu lāʻau.
