ʻO ka PETG kahi plastik PET i hoʻololi ʻia. ʻO ia ka ʻilika ʻālohilohi, he copolyester non-crystalline, PETG comonomer maʻamau ʻo 1,4-cyclohexanedimethanol (CHDM), ʻo ka inoa piha ʻo polyethylene terephthalate-1,4-cyclohexanedimethanol. Hoʻohālikelike ʻia me PET, ʻoi aku ka nui o nā comonomers 1,4-cyclohexanedimethanol, a hoʻohālikelike ʻia me PCT, ʻoi aku ka nui o nā comonomers ethylene glycol. No laila, ʻokoʻa ka hana o PETG mai ka PET a me PCT. ʻIke loa kona mau huahana a loaʻa i ka hopena hopena maikaʻi loa, kūpono loa no ka hana ʻana i nā huahana ʻākala mānoanoa.
Ma ke ʻano he mea paʻi,PETGLoaʻa iā ia nā pono penei:
1. ʻO ka ʻike kiʻekiʻe aʻe, ka transmittance māmā a hiki i 90%, hiki ke hōʻea i ke aniani o ka plexiglass;
2. He ʻoi aku ka ikaika o ka rigidity a me ka paʻakikī, ʻoi aku ka maikaʻi o ka pale ʻana i ka ʻōpala, ka hopena a me ka paʻakikī;
3. Ma keʻano o ke kū'ē kemika, kaʻaila kū'ē, ka hana kū'ē i ka wā (yellowing), ka ikaika mechanical, a me ka hana pale i ka oxygen a me ka mahu wai,ʻoi aku ka maikaʻi o PETG ma mua o PET;
4. Hiki ke ho'ohana 'ia no ka mea'ai, ka lā'au lapa'au a me nā mea 'ē a'e, a hiki ke ho'oma'ema'e 'ia e nā kukuna gamma;
5. Hoʻokō ia i nā koi o ka mālama ʻana i ke kaiapuni a hiki ke hana hou ʻia me ka hoʻokele waiwai a me ka maʻalahi. Ke puhi ʻia ka ʻōpala, ʻaʻohe mea ʻino e hoʻopōʻino i ke kaiapuni.
Ma ke ʻano he mea paʻi,PETLoaʻa iā ia nā pono penei:
1. Loaʻa iā ia nā waiwai mechanical maikaʻi, ʻo ka ikaika o ka hopena he 3 ~ 5 mau manawa o nā kiʻiʻoniʻoni ʻē aʻe, maikaʻi ka pale ʻana i ka pelu, a ʻoi aku ka paʻakikī ma -30 ° C;
2. Kū'ē i kaʻaila, ka momona, ka waikawa dilute, dilute alkali, a me ka hapa nui o nā mea hoʻoheheʻe;
3. Haʻahaʻa kinoea a me ka wai mahu permeability, kinoea maikaʻi loa, ka wai, ka aila a me ke ala kū'ē;
4. Non-toxic, tasteless, hygienic a me ka palekana, hiki ke hoʻohana ponoʻia i loko o ka meaʻai hōʻailona;
5. ʻOi aku ka liʻiliʻi o ke kumukūʻai o nā mea maka ma mua o PETG, a ʻo ka huahana i hoʻopau ʻia he māmā i ke kaumaha a kūpaʻa i ka haki ʻana, kahi mea kūpono i nā mea hana e hoʻemi i nā kumukūʻai hana a me ka lawe ʻana, a he kiʻekiʻe ke kumukūʻai holoʻokoʻa.
ʻOi aku ka maikaʻi o ka PETG ma mua o ka PET maʻamau i nā waiwai ili e like me ka paʻi ʻana a me ka adhesion. Hoʻohālikelike ʻia ka māliko PETG me PMMA. ʻOi aku ka ikaika o ka paʻakikī, ka maʻalahi, a me ka hana hope o ka PETG ma mua o PET. Ke hoʻohālikelike ʻia me PET, ʻike ʻia ka hemahema o ka PCTG, ʻo ia hoʻi, he kiʻekiʻe loa ke kumukūʻai, ʻo ia ka 2 ~ 3 mau manawa o PET. I kēia manawa, ʻo ka hapa nui o nā mea pahu pahu ma ka mākeke he mau mea PET. Loaʻa i nā mea PET nā hiʻohiʻona o ke kaumaha māmā, ke aniani kiʻekiʻe, ke kūpaʻa hopena a ʻaʻole palupalu.
Hōʻuluʻulu manaʻo: ʻO PETG kahi mana i hoʻonui ʻia o PET, me ka ʻike kiʻekiʻe, ʻoi aku ka paʻakikī, ʻoi aku ka maikaʻi o ka hopena, a ʻo ke kumu kūʻai kiʻekiʻe.
