ʻO ka ʻōmole wai ʻano PET Resin (PET)
Hoʻolauna Huahana
He kūpono nā ʻōmole wai wai no ka hana ʻana i nā ʻōmole paʻi no ka wai maʻemaʻe, ka wai mineral maoli, ka wai i hoʻoheheʻe ʻia, ka wai inu, nā mea ʻono a me nā ipu candy, ka ʻōmole makeup a me nā mea pepa PET etc.
Hōʻike ka brand o ka huahana haʻahaʻa haʻahaʻa haʻahaʻa metala haʻahaʻa, haʻahaʻa haʻahaʻa o ka acetaldehyde, waiwai kala maikaʻi, viscosity paʻa.Me kahi papa hana kaʻina hana kūʻokoʻa a me ka ʻenehana hana kiʻekiʻe, loaʻa i ka huahana nā hiʻohiʻona hana maikaʻi loa, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ākea ākea i ka hoʻoili ʻana, ʻike maikaʻi loa a kiʻekiʻe i ka helu huahana.I ka hana ʻana i nā ʻōmole, he liʻiliʻi ka degradation a me ka haʻahaʻa o ka acetaldehyde.ʻOiai e hōʻoiaʻiʻo ana i ka palekana a me ka maʻemaʻe, hiki iā ia ke mālama pono i ka ʻono kūʻokoʻa o ka wai i hoʻomaʻemaʻe ʻia, ka wai mineral a me ka wai i hoʻomaʻemaʻe ʻia.

Nā Kūlana Maʻamau
Pono ka maloʻo ma mua o ka hoʻoheheʻe ʻana i mea e pale ai i ka resin mai ka hydrolysis.ʻO nā kūlana hoʻomaloʻo maʻamau he ea wela o 160-180°C , 4-6 mau hola noho manawa, kehau-point wela ma lalo -40 *C.
ʻO ke ana wela maʻamau ma kahi o 275-293°C.
