I kēia lā, hoʻopuka pōkole i nā waiwai kino o nā plastics

1. Ka hanu
Hōʻailona ʻia ka ea permeability me ka ea permeability a me ka ea permeability coefficient.ʻO ka ea permeability e pili ana i ka leo (mika cubic) o kahi kiʻiʻoniʻoni plastik o kahi mānoanoa ma lalo o kahi ʻokoʻa o 0.1 MPa a me kahi ʻāpana o 1 square square (ma lalo o nā kūlana maʻamau) i loko o 24 mau hola..ʻO ka helu permeability ka nui o ke kinoea e hele ana i loko o ka kiʻiʻoniʻoni plastik ma kēlā me kēia ʻāpana a me ka mānoanoa o kēlā me kēia manawa a me ka ʻokoʻa o ka puʻe ʻāpana (ma lalo o nā kūlana maʻamau).
2. ʻO ka maʻamau permeability
Hōʻike ʻia ka moisture permeability e ka nui o ka hiʻona a me ka coefficient kuanaʻike.ʻO ka moisture permeability ʻo ia ka nuipaʻa (g) o ka mahu wai i hoʻokomo ʻia e kahi kiʻiʻoniʻoni 1 square mika i loko o 24 mau hola ma lalo o nā kūlana o kahi ʻokoʻa puʻupuʻu mahu ma nā ʻaoʻao ʻelua o ke kiʻiʻoniʻoni a me kekahi mānoanoa kiʻiʻoniʻoni.ʻO ka helu kuhi ka nui o ka mahu wai e hele ana ma kahi ʻāpana a me ka mānoanoa o kahi kiʻiʻoniʻoni i loko o kahi manawa ma lalo o kahi ʻokoʻa kaomi ʻāpana.
3. Ka hikiwawe wai
ʻO ke ana ʻana o ka wai permeability ka nānā pono ʻana i ka wai permeability o ka laʻana hoʻāʻo ma lalo o ka hana o kekahi kaomi wai no kekahi manawa.
4. Ka hoʻoheheʻe wai
ʻO ka lawe ʻana i ka wai e pili ana i ka nui o ka wai i hoʻopaʻa ʻia ma hope o ka hoʻokomo ʻia ʻana o ka nui o ke kumu i loko o kekahi ana o ka wai hoʻoheheʻe ʻia ma hope o kekahi manawa.
5. Pili pili a me ka nui
Ma kahi mahana, ua kapa ʻia ka ratio o ka nuipaʻa o ka hāpana me ka nui o ka nui like o ka wai i ka pili pili.ʻO ka nuipaʻa o kahi mea ma kēlā me kēia ʻāpana leo ma kahi mahana i ʻōlelo ʻia e lilo i ka mānoanoa, a ʻo ka ʻāpana he kg/m³, g/m³ a i ʻole g/mL.
6. Hōʻike hoʻohālikelike
ʻO ke kukui e komo ana i ke apo ʻelua mai ka ʻāpana mua (koe wale nō ka hanana kū pololei).ʻO ka sine o kēlā me kēia kihi hanana a me ka sine o ka huina refraction i kapa ʻia ʻo ka refractive index.ʻOi aku ka nui o ka huahelu refractive o ka mea waena ma mua o hoʻokahi, a he ʻano kuhikuhi refractive like ʻole no ka māmā o nā lōʻihi nalu like ʻole.
7. Ka hoʻouna māmā
Hiki ke hōʻike ʻia ke aniani o nā plastics e ka māmā māmā a i ʻole ka haze.
ʻO ka transmittance māmā e pili ana i ka pākēneka o ke kahe ʻālohilohi e hele ana i kahi kino alohilohi a semi-transparent paha i kona hanana ʻana.Hoʻohana ʻia ka transmittance māmā e ʻike i ka ʻike o ka mea.ʻO ke ana i hoʻohana ʻia, he mea ana e ana i ka māmā māmā, e like me ke kiʻi kiʻi kiʻi A-4 hoʻohui home.
Hōʻike ka Haze i ke ʻano ohu a me ka ʻeleʻele o ka loko a i ʻole ka ʻili o nā plastic transparent a i ʻole translucent i hoʻokumu ʻia e ka lūlū māmā, i hōʻike ʻia ma ke ʻano he pākēneka o ke kahe māmā i hoʻopuehu ʻia i ke kālā a me ke kahe māmā i hoʻouna ʻia.

8. ʻAlohilohi
ʻO ka ʻālohilohi e pili ana i ka hiki o ka ʻili o kekahi mea ke hoʻolohilohi i ka mālamalama, i hōʻike ʻia ma ke ʻano he pākēneka (gloss) o ka nui o ka mālamalama i ʻike ʻia mai ka ʻili maʻamau i ke kuhikuhi noʻonoʻo maʻamau o ka hāpana.
9. Moldhōʻemi
ʻO ka hoʻohaʻahaʻa ʻana e pili ana i ka nui o ka nui o ka huahana ma mua o ka nui o ka lua mold mm / mm.
