I kēia lā e hoʻolauna pōkole i nā ʻano kino o nā plastics

1. Ka hanu ʻana
Hōʻailona ʻia ka permeability ea me ka permeability ea a me ke coefficient permeability ea. Pili ka permeability ea i ka nui (mika cubic) o kahi kiʻiʻoniʻoni plastik o kahi mānoanoa ma lalo o kahi ʻokoʻa kaomi o 0.1 MPa a me kahi ʻāpana o 1 mika square (ma lalo o nā kūlana maʻamau) i loko o 24 mau hola. . ʻO ke coefficient permeability ka nui o ke kinoea e hele ana ma o ka kiʻiʻoniʻoni plastik no kēlā me kēia ʻāpana a me ka mānoanoa o kēlā me kēia manawa a me ka ʻokoʻa o ke kaomi o kēlā me kēia (ma lalo o nā kūlana maʻamau).
2. Ka hiki ke komo i ka wai
Hōʻike ʻia ka permeability makū e ka nui o ka hiʻohiʻona a me ke coefficient hiʻohiʻona. ʻO ka permeability makū maoli nō ka nuipa (g) o ka mahu wai i hoʻokomo ʻia e kahi kiʻiʻoniʻoni 1 mika kuea i loko o 24 mau hola ma lalo o nā kūlana o kahi ʻokoʻa kaomi mahu ma nā ʻaoʻao ʻelua o ke kiʻiʻoniʻoni a me kahi mānoanoa o ke kiʻiʻoniʻoni. ʻO ke coefficient hiʻohiʻona ka nui o ka mahu wai e hele ana ma kahi ʻāpana a me ka mānoanoa o kahi kiʻiʻoniʻoni i kahi manawa ma lalo o kahi ʻokoʻa kaomi.
3. Ka hiki ke komo i ka wai
ʻO ke ana o ka permeability wai ke nānā pololei i ka permeability wai o ka hāpana hoʻāʻo ma lalo o ka hana o kekahi kaomi wai no kekahi manawa.
4. Ka omo ʻana o ka wai
ʻO ka omo ʻana o ka wai e pili ana i ka nui o ka wai i omo ʻia ma hope o ka hoʻokomo ʻia ʻana o kekahi nui o ke ʻano i loko o kekahi nui o ka wai i hoʻoheheʻe ʻia ma hope o kekahi manawa.
5. Ka nui a me ka nui o ka pilina
Ma kekahi mahana, ua kapa ʻia ka lakio o ke kaumaha o ka hāpana i ke kaumaha o ka nui like o ka wai ʻo ka nui pili. ʻO ke kaumaha o kahi mea no kēlā me kēia anakahi nui ma kahi mahana i kuhikuhi ʻia e lilo i ka nui, a ʻo ke anakahi he kg/m³, g/m³ a i ʻole g/mL.
6. Ka helu kuhikuhi refractive
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 kekahi kihi hanana a me ka sine o ke kihi refraction ua kapa ʻia ʻo ka refractive index. ʻOi aku ka nui o ka refractive index o ka medium ma mua o hoʻokahi, a he ʻokoʻa nā refractive index o ka medium like no ka mālamalama o nā nalu like ʻole.
7. Ka hoʻoili ʻana o ka mālamalama
Hiki ke hōʻike ʻia ke ʻano moakaka o nā plastics e ka lawe ʻana o ka mālamalama a i ʻole ka noe.
ʻO ka transmittance o ka mālamalama e pili ana i ka pakeneka o ke kahe mālamalama e hele ana ma o kahi kino moakaka a semi-moakaka paha i kona flux mālamalama i hoʻokomo ʻia. Hoʻohana ʻia ka transmittance o ka mālamalama e wehewehe i ka moakaka o ka mea. ʻO ke ana i hoʻohana ʻia he mea ana transmittance kukui holoʻokoʻa, e like me ka photometer sphere hoʻohui kūloko A-4.
ʻO ka Haze e pili ana i ke ʻano ao a me ka ʻūlū o loko a i ʻole ka ʻili o nā plastics moakaka a translucent paha i hoʻokumu ʻia e ka hoʻopuehu ʻana o ka mālamalama, i hōʻike ʻia ma ke ʻano he pakeneka o ka lele ʻana o ka mālamalama i hoʻopuehu ʻia i ke kālā a me ka lele ʻana o ka mālamalama i hoʻouna ʻia.

8. ʻĀlohilohi
ʻO ka ʻōlinolino e pili ana i ka hiki o ka ʻili o kahi mea ke hōʻike i ka mālamalama, i hōʻike ʻia ma ke ʻano he pakeneka (ʻōlinolino) o ka nui o ke kukui i hōʻike ʻia mai ka ʻili maʻamau ma ke kuhikuhi ʻōlinolino maʻamau o ka hāpana.
9. ʻŌpalaemi ʻana
ʻO ka hoʻemi ʻana o ka hoʻoheheʻe ʻana e pili ana i ka nui o ka nui o ka huahana i ʻoi aku ka liʻiliʻi ma mua o ka nui o ka lua hoʻoheheʻe mm/mm
