Whakamahinga
Ko te pāhare pākawa waro, e mōhiotia whānuitia ana ko te pāhare pākawa waro, ko te pāhare pākawa waro rānei, e rua ngā āhua ahumahi e kitea ana: he totoka me te wai. Ko te āhua totoka he rite ki te ma, ki te hina mārama rānei, he poraka, he tokotoko rānei, ko te āhua wai he wai kōwhai mā. He rite ōna āhuatanga matū ki ērā o te pāhare pākawa waro, he kaha te kawakore me te waikura. He ngāwari te wairewa ki te wai, ā, he nui te wera e tukuna ana, e whakaatu ana hoki i te ngawari o te mimiti i te makuku mai i te hau, ka mimiti, ā, ka taea te tauhohe ki te hauhā waro hei hanga pāhare pākawa waro. Ina wairewahia ki te wai, ki te waipiro, ki te waikawa rānei, ka tukuna he nui te wera. Ko te pH o te otinga 0.1 mol/L he 13.5 (kore wai). He paitini ngawari, me te horopeta whakamate toharite (waha, kiore) he 1230 mg/kg. I tēnei wā, ko te pāhare pākawa waro e whakamahia ana hei hanga pāhare pākawa waro, pāhare pākawa waro, me ētahi atu, ā, e whakamahia ana i roto i ngā ahumahi matū, kai, rongoā, me te ahuwhenua.
Ko te pāhare pākawa waro te nuinga o te wā e whakamahia ana hei rauemi mata mō te hanga tote pāhare pākawa, pērā i te pāhare pākawa waro me te pāhare pākawa waro. I roto i te umanga rongoā, ka whakamahia hei hanga pāhare pākawa borohydride, Antishutong, silybin, progesterone, me te testosterone propionate. I roto i te umanga rama, ka whakamahia hei hanga hopi pāhare pākawa, pākahiko kawakore, me ngā mea whakapaipai (pērā i te kirīmi makariri, te kirīmi hukarere, me te shampoo). I roto i te umanga tae, ka whakamahia hei hanga tae ipu, pērā i te RSN kikorangi ipu. I roto i te umanga hiko, ka whakamahia mō te whakakikorua hiko, te whakairo, me ētahi atu. I roto i te umanga kakahu, ka whakamahia mō te tā, te tae, te whakama, me te mercerizing, ā, he whānuitia hoki te whakamahinga hei rauemi mata matua mō te hanga muka horihori me ngā muka polyester. Hei tāpiri, ka whakamahia hoki i roto i ngā kaihoko whakamahana whakarewa me te tango hinu hiako, me ētahi atu mahi.
Te Tākai me te Tukunga
25KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Nō ngā taonga noa, ā, ka taea te tuku mā te moana me te rangi
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.
