Ko te rauemi PS he polystyrene.
He kirihou wera te polystyrene, he pai rawa ngā āhuatanga ārai wera, ā, he pai hoki te tukatuka. He momo rauemi polymer hou tēnei, kāore he paitini, kāore he kakara, ā, he pai hoki mō te taiao. Ko ngā kōrero e whai ake nei mō te polystyrene
1. Whakamāramatanga Taketake
He pūhui te polystyrene i hangaia mā te whakakotahitanga o ngā monomers styrene. He tino mārama, he ātete hoki ki te pānga, nō reira he whānuitia te whakamahinga i roto i te hanga i ngā ipu, ngā rauemi tākai, me ngā rauemi tiaki. Hei tāpiri, he pai hoki te pumau matū o te rauemi PS, ā, ka taea te ātete ki te pirau o ngā matū rerekē.
2. Ngā Āpure Tono
Nā te pai o ōna āhuatanga ā-tinana me te matū, he whānuitia ngā whakamahinga o te polystyrene i roto i ngā momo mara. Hei tauira, i roto i te mara o te hoahoanga, ka whakamahia hei hanga i ngā momo paipa, ngā panera pakitara, me ngā rauemi whakamarumaru pakitara o waho. I roto i te mara o te takai, nā te pai o tōna āhua hanga me tōna ātete ki te pānga, ka whakamahia whānuitia i roto i te hanga ipu takai me ngā whakakī o roto. Hei tāpiri, ka whakamahia whānuitia ngā rauemi PS i roto i ngā mara pēnei i ngā hua hiko, ngā taonga takaro, me te hanga wāhanga motuka.
3. Ngā āhuatanga me ngā painga
Ko ngā āhuatanga matua o te polystyrene e whai ake nei:
1. He mārama teitei, he pai hoki te pānga whakaatu.
2. He ngāwari ki te tukatuka me te hanga, ka taea te whakatutuki i ngā hiahia o ngā momo āhua uaua.
3. He ātete kaha ki te pānga, ka taea te tu atu ki ētahi pēhanga me te pānga.
4. He pai te pumau o te matū, ā, ka taea te ātete i te mimiti o ngā momo matū.
5. He iti te utu, he nui te whai huatanga.
Hei whakarāpopototanga, he mea nui te rauemi PS hei kirihou wera, he whānuitia ngā whakamahinga i roto i ngā mara maha. Nā tōna mahi tino pai me te utu iti, he mea nui te polystyrene i te mākete.
