ʻAʻole loli ka mānoanoa o ka pepa metala i ka wā o ka perforation.
Hōʻike ʻia ka mānoanoa ma ke ana.Eia naʻe, i mea e pale aku ai i ka hiki ʻole ke hoʻomaopopo ʻole ʻia ʻo Thickness, manaʻo mākou e hōʻike iā lākou ma nā iniha a i ʻole millimeters.
ʻO ka laulā maʻamau a me ka lōʻihi e like me kēia:
Eia nō naʻe, hana mākou i nā nui ʻē aʻe e like me nā koi a nā mea kūʻai aku.
ʻO nā ʻaoʻao ka ʻāpana hakahaka (ʻaʻole i paʻa ʻia) ma nā ʻaoʻao o ka pepa.ʻO ka maʻamau ka palena ma ka lōʻihi he 20mm ka liʻiliʻi, a ʻo ka palena ma ka laula hiki ke 0 liʻiliʻi a i ʻole ma nā noi a nā mea kūʻai aku.
Hoʻonohonoho maʻamau ʻia ka puka pōʻai i 3 ʻano:
Hiki ke hana ma'amau i nā kumu hole a me ka ho'onohonoho puka.
Hiki ke hana ma'amau i nā kumu hole a me ka ho'onohonoho puka.
Hiki i ka pepa metala perforated ke hana i ka ʻoki a me ka pelu ʻana ma hope o ka puka ʻana.
Hiki i ka pepa metala perforated ke hana i ka pau ʻana e like me nā koi o nā mea kūʻai aku.
Hoʻopau kūlohelohe
ʻO ka hapa nui inā makemake ʻia ka pepa perforated e hoʻopau kūlohelohe ʻoiai ʻo ke ʻano o ia mea.
Ka ʻaila ʻaila
Makemake kekahi mau mea kūʻai aku i ka ʻaila ʻaila i hoʻoheheʻe ʻia i ke kila kalapona i mea e pale aku ai i ka pala ma muli o ka wai i ka wā lōʻihi o ka hoʻouna ʻana i ke kai.
ʻO ka pauka
Hiki i ka pepa metala perforated ke hana i nā kala like ʻole i ka pauka, akā makemake ʻia ka liʻiliʻi no kekahi kala kūikawā.
ʻO ka ʻāpana hāmama ka ratio ma waena o ka nui o ka ʻāpana o nā lua a me ka nui o ka ʻāpana pepa, ma ke ʻano maʻamau e hōʻike ʻia e ka pakeneka, no ka laʻana no kahi pepa perforated me nā kikoʻī penei:
Puka poepoe 2mm nui puka, 60 degere staggered, 4mm pitch, pepa nui 1mX2m.
E like me ka ʻike ma luna a ma muli o ka formula. hiki iā mākou ke kiʻi i ka wahi ākea o kēia pepa he app 23%, ʻo ia hoʻi ka nui o nā lua o kēia pepa he 0.46SQM.
