He mau mea moakaka loa ʻo PETG a me PMMA, a ma ka hoʻohālikelike ʻana, ʻoi aku ka maʻa o ka mākeke me PMMA. Eia nō naʻe, ua hoʻomaka ke komo maoli ʻana o PETG i ka mākeke me ka ʻōpala plastik moakaka no nā mea hoʻonani kiʻekiʻe. Ma mua o ka hoʻokuʻu ʻia ʻana o PETG, ua hoʻohana ʻia ka PMMA no ka ʻōpala plastik moakaka o nā mea hoʻonani kiʻekiʻe. A laila he aha nā ʻano like a me nā ʻokoʻa ma waena o nā mea ʻelua? Hiki ke hōʻuluʻulu ʻia nā ʻokoʻa penei:

1. ʻAʻole ʻino ka pale ʻana o ka PMMA i ka solvent e like me ko PETG. Ma hope o ka hoʻopili ʻana me nā mea he nui, maʻalahi ka PMMA e hoʻokeʻokeʻo, no laila he nui nā huahana, ʻoi aku ka mea hoʻonani, pono i ka liner kūloko e ālai i kā lākou ʻōpala, ʻoiai ʻaʻohe pilikia o PETG;

2. Loaʻa iā PMMA a me PETG nā waiwai optical maikaʻi loa, ʻili ʻālohilohi kiʻekiʻe a me ka turbidity haʻahaʻa. ʻO ka transmittance o nā mea ʻelua ua kokoke i ko PETG, kokoke i 90%.

3. ʻAʻole maikaʻi ka waiwai tensile, ka paʻakikī a me ke kūpaʻa hopena o PMMA e like me ko PETG, ʻoi aku ka kūpaʻa hopena;

4. Hoʻopili ponoʻī ʻo PETG, maikaʻi ka paʻi ʻana, ʻaʻole pono ka mālama ʻana i ka corona i kāna huahana;

5. ʻOi aku ke kiʻekiʻe o PETG ma mua o PMMA.

I loko o kā mākou hale hana, no kēia mau mea ʻelua, makemake mākou i ka mea PMMA, hoʻohana nui ʻia ka mea PMMA, a he koho maikaʻi ia ma ke ʻano o ke kumukūʻai a me ka maikaʻi.

ʻO kekahi o nā mea a mākou e makemake nui ai e pili ana i ka PMMA ʻo ia kona kūpaʻa, a he kūpaʻa ko nā mea PMMA i ka mālamalama, ʻo ia hoʻi, ʻaʻole i hoʻonui ʻia ka oxidation o ka PMMA. ʻO nā mea optical ʻē aʻe, ʻo PETG a i ʻole PC, e hoʻonui ʻia lākou, a i ka wā e waiho ʻia ai kēia mau huahana no kekahi manawa, e melemele lākou, ʻo ia hoʻi ka o xidation. ʻOiaʻiʻo, e hoʻonui pū ʻia nā mea PMMA, akā e lohi loa ke kekelē o ka oxidation, no laila ua hoʻohana nui ʻia nā mea PMMA i nā kukui kaʻa.

Inā makemake ʻoe e hana i nā huahana optical, hiki iā ʻoe ke loaʻa i kā mākou hale hana. He ʻike nui ko kā mākou hale hana i ka hoʻohana ʻana i nā mea optical a me ka hana ʻana i nā huahana optical. Ma ke ʻano o nā mea maka, ka hana ʻana i ka mold, ka hana huahana, ka hoʻopili ʻana, hiki iā mākou ke hoʻokō piha i nā koi āpau o nā mea kūʻai aku. (Loaʻa iā mākou nā lawelawe paʻi a me ka uhi ʻana)
