Waikura etirenahe pūhui rauropi me te tauira matūC2H4OHe matū whakaputa mate pukupuku paitini tēnei, ā, e whakamahia ana hei hanga i ngā patu harore. He mura, he pahū hoki te waikura ethylene, ā, ehara i te mea ngāwari ki te kawe i ngā tawhiti tawhiti, nō reira he āhua ā-rohe kaha tōna.
He aha ngā mea me aro atu ahau ina penapena ana i te ethylene oxide?
Waikura etirenakei roto i ngā tāke porowhita e rongoatia ana, ā, kei roto ngā tāke porowhita i te pouaka whakamātao, ā, he iti iho i te 10 nekehanga te pāmahana rokiroki. Nā te mea he iti rawa te pūwāhi mura me te pahūtanga-ake o te mowhiti B, he haumaru ake te rongoa i roto i te tio.
1. Tāke whakapae (ipu pēhanga), Vg=100m3, he pouaka whakamatao kua hangaia ki roto (he koti, he momo koiri rānei o roto, me te wai whakamatao), he hiri hauota. He ārai me te poraka polyurethane
2. Ko te pēhanga whakamahere te mea e tango ana i te uara pēhanga teitei rawa atu o te pūnaha tuku hauota (EO(e kore te rokiroki me te hiri hauota e pā ki tōna parakore, ā, ka taea hoki e ia te whakaiti i te mōrearea o te pahūtanga).
3. Pūwhakamatao kua hangaia: Ko te paihere ngongo (te uho rānei) o te whakawhiti wera ngongo-U. Kua whakamaheretia kia waiho hei momo wetewete, he watea mō te tiaki me te whakakapi.
4. Kua mau te pōkai whakamatao kua hangaia ki roto: kāore e taea te tango i te paipa whakamatao ngokingoki i roto i te tāke rokiroki.
