He aha nā ʻokoʻa ma waena o nā mea PC a me nā mea PET no ka lipine lawe?

He aha nā ʻokoʻa ma waena o nā mea PC a me nā mea PET no ka lipine lawe?

Mai ka manaʻo manaʻo:

PC (Polycarbonate): He ʻilika kala ʻole kēia, ʻalohilohi i ʻoluʻolu a ʻoluʻolu. Ma muli o kona ʻano ʻawaʻawa ʻole a ʻala ʻole, a me kāna mau mea pale UV maikaʻi loa a me ka mālama ʻana i ka wai, he ākea ākea ka PC. ʻAʻole hiki ke haʻihaʻi ʻia ma -180 ° C a hiki ke hoʻohana lōʻihi i ka 130 ° C, e lilo ia i mea kūpono no ka hoʻopili ʻana i nā meaʻai.

kiʻi uhi

PET (Polyethylene Terephthalate) : He mea kalakala kiʻekiʻe loa kēia, waihoʻoluʻu, a ʻaʻohe mea paʻakikī loa. He ʻano aniani kona ʻano, ʻaʻohe ʻala, ʻono ʻole, a ʻaʻohe mea ʻawaʻawa. He lapalapa ia, e hoʻopuka ana i ka lapalapa melemele me ka ʻaoʻao polū ke puhi ʻia, a loaʻa iā ia nā waiwai pale kinoea maikaʻi.

Mai ka hiʻohiʻona o nā ʻano a me nā noi:

PC: Loaʻa i ka hopena maikaʻi loa a maʻalahi ke hoʻoheheʻe ʻia, e ʻae ʻia e hana ʻia i loko o nā ʻōmole, nā ipu, a me nā ʻano pahu like ʻole no ka hoʻopili ʻana i nā wai e like me nā mea inu, waiʻona, a me ka waiū. ʻO ka drawback koʻikoʻi o ka PC ʻo ia ka maʻalahi o ke koʻikoʻi. No ka hoʻohaʻahaʻa ʻana i kēia i ka wā o ka hana ʻana, koho ʻia nā mea maka maʻemaʻe kiʻekiʻe, a mālama ʻia nā ʻano hana like ʻole. Eia hou, me ka hoʻohana ʻana i nā resins me ke koʻikoʻi haʻahaʻa o loko, e like me ka liʻiliʻi o nā polyolefins, nylon, a i ʻole polyester no ka hoʻoheheʻe ʻana, hiki ke hoʻomaikaʻi maikaʻi i kona kūʻē ʻana i ke koʻikoʻi a me ka lawe ʻana i ka wai.

PET: He haʻahaʻa haʻahaʻa o ka hoʻonui a me ka haʻahaʻa haʻahaʻa shrinkage shrinkage o 0.2% wale nō, ʻo ia ka hapaʻumi o nā polyolefins a haʻahaʻa ma lalo o PVC a me ka nylon, e hopena i nā ana paʻa no nā huahana. ʻO kona ikaika mechanical ka mea maikaʻi loa, me nā mea hoʻonui e like me ka alumini. ʻO ka ikaika tensile o kāna mau kiʻiʻoniʻoni he ʻeiwa manawa ma mua o ka polyethylene a ʻekolu mau manawa o ka polycarbonate a me ka nylon, ʻoiai ʻo kona ikaika hopena ʻekolu a ʻelima mau manawa ma mua o nā kiʻiʻoniʻoni maʻamau. Hoʻohui ʻia, loaʻa i kāna mau kiʻiʻoniʻoni nā mea pale a me nā waiwai mālama ʻala. Eia nō naʻe, ʻoiai kēia mau mea maikaʻi, ʻoi aku ka pipiʻi o nā kiʻiʻoniʻoni polyester, paʻakikī i ka hoʻopaʻa ʻana i ka sila, a hiki i ka uila static, ʻo ia ke kumu e hoʻohana ʻole ʻia ai lākou; Hoʻohui pinepine ʻia lākou me nā resins i ʻoi aku ka maikaʻi o ka hoʻopaʻa ʻana i ka wela e hana i nā kiʻiʻoniʻoni composite.

No laila, ʻo nā hue PET i hana ʻia me ka biaxial stretching blow molding process hiki ke hoʻohana piha i nā hiʻohiʻona o ka PET, e hāʻawi ana i ke aniani maikaʻi, ke aniani kiʻekiʻe, a me ke ʻano aniani, e hoʻolilo iā lākou i nā hue plastik kūpono loa e hoʻololi i nā hue aniani.
