Ka whakamahia hei rauemi mata mo nga poaka tae i roto i te ahumahi waikano.

 

Tikanga:

Ko nga tikanga whakarite o te azodicarbonamide te nuinga e whai ake nei:

He mea hanga na te tauhohenga o te waikawa nitrous me te dimethylurea.

Ka puta mai i te tauhohenga o te dimethylurea wairewa me te dimethylurea i timatahia e te waikawa nitric.

 

Mōhiohio Haumaru:

He tino pahū te Azodicarboxamide, me noho matara atu i te mura, te waku, te wera me etahi atu matū muramura.

Me mau nga karapu whakamarumaru tika, nga karaehe me nga kanohi kanohi ina whakamahi i te azodicarbonamide.

A ape i te pa atu ki nga waikura me nga mura ahi i te wa e mahi ana.

Ko te Azodicarbonamide me penapena ki tetahi waahi hiri, hauhautanga, he pai te hau i tawhiti atu i te ra tika.
