Te tono hua

EDMKa taea te whakamahi hei whakarewa mō te nitrocellulose, te kapia hangai, te peita me te waituhi tā. Ka taea te whakamahi hei whakarewa muku peita me te waiwhakarewa nā te mea he tino pai te wairewa. Ka taea hoki te whakamahi hei whakarewa koretake hangai waro nā te mea he pumau matū.
Haunga te whakamahinga kua whakahuatia ake nei,DEDMka taea te whakamahi hei whakarewa mō te peita wairewa-wai, hei kaiwhakarite i te hiako me te muka, hei kaiwhakarite i roto i te whakaahua, i te tānga rānei, me te whakarewa āporotika porotiki e whakamahia ana i roto i te hanga matū waro.

TRIEDMka taea te whakamahi i roto i te tauhohenga o te hanga rauropi hei whakarewa ira-kohua teitei. Ka taea hoki te whakamahi hei kaihoko tango-whanariki, hei kaihoko tango-waro rānei mō te haukini hanga, te hau maori rānei.

TETREDMKa taea te whakamahi hei whakarewa pai rawa atu mō te hydride whakarewa kawakore, ā, ka whakamahia hoki i roto i te whakakotahitanga alkyl, i te hangarua rānei i te tauhohenga matū. Mā te Louise Alkalinity, ka taea e ia te mimiti i te hau waikawa hei pure i te hau hangai, te hau maori me te acetylene. (WHAKAMAHI: kāore e taea te whakaatu i tēnei hua ki waho mō te wā roa, ki te kore ka puta he peroxide.)
