Whakamahinga
Ko te Dioctyl terephthalate (DOTP) he matū hanga kirihou matua, he tino pai te mahi mō ngā kirihou polyvinyl chloride (PVC). Ki te whakatauritea ki te diisooctyl phthalate (DOP) e whakamahia whānuitia ana, he pai ōna painga o te ātete wera, te ātete makariri, te uaua ki te mimiti, te ārai i te tangohanga, te ngawari, me ngā āhuatanga pai o te whakamarumaru hiko. He tino pakari, he ātete ki te wai hopi me te ngawari ki te pāmahana iti i roto i ngā hua. Nā te iti o te mimiti, ka taea e te whakamahinga o te DOTP te whakatutuki i ngā whakaritenga ātete pāmahana o ngā waea me ngā taura, ā, ka taea te whakamahi whānui i roto i ngā rauemi taura e ātete ana ki te 70° C (paerewa IEC o te International Electrotechnical Commission) me ētahi atu hua ngohengohe PVC.
Haunga te maha o ngā mea whakapūkara mō ngā rauemi taura me te PVC, ka taea hoki te whakamahi i te DOTP i roto i te hanga kiriata hiako horihori. Hei tāpiri, he tino pai te wairewatanga o te DOTP, ā, ka taea hoki te whakamahi hei mea whakapūkara mō ngā hua acrylonitrile, polyethylene, waipiro butyraldehyde, rapa nitrile, nitrocellulose, me ētahi atu. Ka taea hoki te whakamahi hei mea whakapūkara mō te rapa hangai, hei tāpiri paninga, hei hinu whakahinuhinu taputapu tika, hei tāpiri hinu whakahinuhinu, me hei whakangawari mō te pepa.
Te Tākai me te Tukunga
Tākai: 250 kg/pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Tukunga: nō ngā matū noa, ā, ka taea te tuku mā te tereina, te moana me te rangi.
Taonga: he 500MTs te taonga haumaru
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
