He aha ngā hauwaiwaro (HC)

Ko ngā hauwaiwaro he matū waro e rua noa iho ngā momo ngota – te waro me te hauwai. He mea hanga noa ngā hauwaiwaro, ā, koinei te pūtake o te hinu mata, te hau māori, te waro, me ētahi atu puna pūngao nui. He tino mura, ā, ka puta he hauhā waro, he wai, me te wera ina tahuna. Nō reira, he tino whai hua ngā hauwaiwaro hei puna wahie. Ko ngā hauwaiwaro he hau kore tae, he ngoikore te kakara.

 

He aha ngā momo warowaihā e whā?

He māmā noa iho, he uaua rānei ngā hanganga o ngā hauwaiwaro, ā, ka taea te whakarōpū whānuitia kia whā ngā wāhanga iti, arā, ko ngā alkane, ngā alkene, ngā alkyne, me ngā hauwaiwaro kakara.

He aha ngā whakamahinga o ngā hauwaiwaro?

• Ko ngā hauwaiwaro pēnei i te propane me te butane e whakamahia ana mō ngā mahi hinu arumoni i roto i te ahua o te Hau Hinu Wai (LPG). Ko te Benzene, tētahi o ngā hauwaiwaro kakara māmā rawa, he rauemi mata mō te hanga i ngā rongoā hangai maha.
• Ka whakamahia ēnei hei pūtake wahie mura, hei tauira: Ko te Methane te wāhanga o te hau māori.
• Ko te penehīni, te wahie jet me te naphtha he hauwaiwai aliphatic e whakamahia nuitia ana i roto i ngā ahumahi rerekē.
• He momo warowaihā ngā matū tuanui, te uku, te hanganga ara rānei, me ngā mea tiaki rakau.
• Ko ā rātou whakamahinga hei hinu kore-wahie nui pērā i te ethane me te propane ka puta mai i te hinu me te hau māori. Ka taea hoki te huri i ēnei hau e rua hei ethylene me te propylene.
• E mōhiotia ana ngā warowaihā motuhake pēnei i te ranunga o te benzene, toluene me te xylene isomers, ā, he tino nui te whakamahinga o aua warowaihā.
• Kei roto i ngā pī Brazil kore-ngau ngā warowaihā tūturu, ā, ka waiho e rātou he kakara warowaihā ahurei, ā, ka āwhina i te whakatau i te whanaunga mai i te hunga ehara i te whanaunga.

 

He aha ngā whakamatao hauwaiwai?

 Ko ngā pouaka whakamatao hauwaiwaro he mea e mōhiotia ana ko ngā 'pouaka whakamatao taiao'. Kāore e paitini, kāore e whakaiti i te rohe-O, ā, he iti rawa te Pūmanawa Mahana Ao. Haunga ēnā mea katoa, ko tētahi o ngā pouaka whakamatao tino whai hua o te ao i ēnei rā.

 Kei te tata te mutunga o te whakamahinga o ngā hau whakamatao hau fluorine, ā, ka mutu katoa ēnei puta noa i te ao i roto i ngā tekau tau e whai ake nei. Ka whakakapia rātou e ngā hau whakamatao hauwaiora. Kua rongonui kē ngā hauwaiora puta noa i Ūropi me Āhia, ā, e whakamahia ana i roto i ngā pouaka whakamātao. Pērā i ngā wā katoa, kei te whakaroa te Hononga o Amerika i te toenga o te ao ina tae mai ki ngā hau whakamatao rerekē… engari homai he wā, ā, ka tīmata koe ki te kite i te puta haere o ngā hauwaiora puta noa i te US.

 Ko ētahi tauira o te wai whakamatao hauwaiwai e whai ake nei:

 R-290(Pōpana)

 R-600a(Isobutane)

 R-1150(Etene/Eterene)

 R-1270(Pōpene/Pōpirēne)

 R-170(Etana)
