He tioata mā, he paura tioata mā rānei, ka wairewa i roto i te wai, i te waipiro me ētahi atu whakarewa waro. He waikawa tōna otinga wai.
1,2,3,4-Waikawa Pūtanetetracarboxylic (BTCA) He mea tino pai te mīhini tā roa (DP) kāore he formaldehyde. He kaha te tauhohenga, ā, kāore he haunga whakapataritari. Mā te BTCA ka taea e ngā papanga pēnei i te miro me te hiraka te whakatutuki i ngā āhuatanga tae atu ki te ārai-mutu, te pēhi pumau me te pupuri i te āhua, ā, he tino pakari.
BTCA ka taea te whakamahi hei whakarite rauemi polyimide. He tino pai te ātete wera o tēnei momo rauemi, he ātete waikawa, he ātete hauwaiwai, ā, he pai hoki ngā āhuatanga whakamahana hiko, ā, ka taea te whakamahi hei whakarite i ngā momo rauemi polymer mahi, pērā i ngā rauemi photosensitive, ngā rauemi polymer hauora me ngā rauemi membrane polymer mahi. Ka taea te whakamahi hei whakarite i ngā mowhiti whakamahana hiko, ngā paninga waea me ngā rauemi whakamahana hiko.
Pēke pepa hiato 25kg - whakakanapa - rakau rinena, e ai ki ngā hiahia o te kiritaki.
Rokiroki:
Penapenahia kia mau ki roto i te wāhi marumaru, kia pai te hauhautanga. E 12 marama te roa o tōna oranga. Ka taea tonu te whakamahi mēnā kua pau te wā.
Te kawe waka:
Āraia te wera nui me te werawera o te rā i te wā e kawe ana.
