Ko te PBT te whakarāpopototanga o te Polybutylene terephthalate. Kei roto i te raupapa polyester. He mea tito mai i te 1.4-Butylene glycol me te waikawa terephthalic (TPA) terephthalate rānei (DMT). He kapia polyester thermoplastic mārama ki te opaque, he tioata, he rite ki te miraka, i hangaia mā te tukanga whakakotahi. I te taha o te PET, ka kiia ngātahitia ko te polyester thermoplastic, ko te polyester kukū rānei.
Ngā Āhuatanga o ngā Kirihou PBT
1. He tino pai te ngāwari o te kirihou PBT, ā, he tino ātete hoki ki te hinga, ā, he kaha tōna ātete pakarukaru.
2. Kāore te PBT e mura pērā i ngā kirihou noa. Hei tāpiri, he tino teitei te mahi tinei-ā-unoa me ōna āhuatanga hiko i roto i tēnei kirihou wera-mahana, nō reira he tino nui te utu i waenga i ngā kirihou.
3. He tino iti te mahi mimiti wai o te PBT. Ka ngāwari te whakapohehe i ngā kirihou noa i roto i te wai me te pāmahana teitei ake. Kāore he raruraru o te PBT. Ka taea te whakamahi mō te wā roa, ā, he tino pai tonu te mahi.
4. He tino maeneene te mata o te PBT, ā, he iti te tauwehenga waku, he mea ngāwari ake te whakamahi. Nā te iti hoki o te tauwehenga waku, he maha tonu te whakamahinga i ngā wā e nui ana te ngaronga waku.
5. He tino pakari te pumau o te kirihou PBT i te mea kua hangaia, ā, he tino tika ake te āhua o ngā āhuatanga, nō reira he rauemi kirihou kounga teitei. Ahakoa i roto i ngā matū roa, ka taea e ia te pupuri i tōna āhua taketake, engari ko ētahi matū pēnei i ngā waikawa kaha me ngā kawakawa kaha.
6. He maha ngā kirihou he kounga whakapakari, engari kāore ngā rauemi PBT. He tino pai ōna āhuatanga rere, ā, ka pai ake ōna āhuatanga mahi i muri i te whakapūtanga. Nā te mea e whakamahi ana i te hangarau whakakotahitanga polymer, ka tutuki i a ia ētahi āhuatanga koranu e hiahia ana ki te polymer.
Ngā whakamahinga matua o te PBT
1. Nā ōna āhuatanga ā-tinana me ā-matū pai, ka whakamahia te PBT hei rauemi whakaputa mō te paninga tuarua o ngā muka whatu i roto i te taura muka whatu o waho.
2. Ngā tono hikohiko me te hiko: ngā hononga, ngā wāhanga pana, ngā taputapu whare, ngā taputapu tāpiri rānei (ātete wera, ātete mura, ārai hiko, ngāwari ki te hanga me te tukatuka).
3. Ngā mara tono o ngā wāhanga motuka: ngā wāhanga o roto pērā i ngā whāriki horoi, ngā takirere pūnaha whakahaere, me ētahi atu; ngā wāhanga hiko me ngā wāhanga hiko pērā i ngā paipa miro o te koiri mura motuka me ngā hononga hiko e pā ana.
4. Ngā mara tono taputapu mīhini whānui: taupoki rorohiko, taupoki rama mercury, taupoki rino hiko, wāhanga mīhini tunu me te maha o ngā taputapu, ngā kāmera, ngā pātene, ngā anga mataaratanga hiko, ngā wiri hiko me ētahi atu anga mīhini.
