HANGANGA:
Whakaahuatanga:
He matū waro te waikawa isophthalic, ko tōna tauira C6H4(CO2H)2. Ko tēnei totoka kore tae he isomer o te waikawa phthalic me te waikawa terephthalic. Ka whakamahia ēnei waikawa dicarboxylic kakara hei matū mua (i roto i te āhua o ngā acyl chlorides) ki ngā polymer nui arumoni, hei tauira, te rauemi ātete ahi Nomex. I konatunatua ki te waikawa terephthalic, ka whakamahia te waikawa isophthalic ki te hanga kapia mō ngā pounamu inu. Ka hangaia te polymer mahi-teitei poly benzimidazole mai i te waikawa isophthalic.

Whakamahinga
Ka whakamahia te waikawa isophthalic hei takawaenga mō ngā polyesters kore-mākū mahi teitei, ngā kapia mō ngā paninga, ngā peita totoka teitei, ngā paninga gel me te whakarerekētanga o te polyethylene terephthalate mō ngā pounamu. Ka mahi hei matū mua mō te rauemi ātete ahi nomex me te whakamahi hoki i roto i te hanga o te polymer mahi teitei polybenzimidazole. Ka whakamahia hoki hei whakauru mō te hanga rauemi whakamahana.
Ko te Waikawa Isophthalic Parakore (PIA) e whakamahia whānuitia ana hei takawaenga mō te UPR mahi teitei, ngā kapia mō ngā paninga, ngā peita totoka teitei, ngā paninga tiēre, me te whakarerekētanga o te PET mō ngā pounamu.
Tākai
25KG/Pēke rānei kia rite ki ngā whakaritenga a te kiritaki.
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.
