Whakamahinga
He rauemi mata nui ngā pūhaumāota waikawa mō te hanga i ētahi atu pūhui waro, ā, e whakamahia whānuitia ana i roto i ngā mara o ngā rongoā, ngā tae, ngā patupatu me ngā paninga.
Ka taea te whakamahi hei hanga i ngā matūriki acyl chloride pērā i ngā acyl chloride esters, ngā amides, me ngā acyl chloride ethers.
I hangaia te hauota kokoiira mā te tauhohe i te phosgene me te waikawa ngako kokonati i raro i ngā āhuatanga kāore he whakakorikori, he pāmahana teitei, ā, he whakakorenga tae o te waro whakahohe. I tirotirohia ngā pānga o te pāmahana tauhohenga, te ihirangi waro whakahohe me te tere o te hau phosgene ki te ihirangi wāhanga, te hua me te tae o te hua chloride kokoiira. E whakaatu ana ngā hua ina 120 ℃ te pāmahana tauhohenga, ko te ōwehenga papatipu o te waro whakahohe ki te waikawa ngako kokonati he 1.5%, ā, ko te tere o te hau phosgene he 0.8 L/min, ka taea e te hua o te chloride kokoiira te eke ki te 96%, ā, ko te tae o te APHA he 130.
Te Tākai me te Tukunga
Tākai: 20 kg/pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Tukunga: Nō te Akomanga 8 ngā matū, ā, ka taea te tuku mā te moana.
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.
