He whānuitia te whakamahinga o te pōro kowiri tira i roto i te hanga mīhini ahumahi, ā, he mahi nui tāna e kore e taea te whakakapi. He rerekē te whakamahinga o te pōro kowiri tira, e ai ki ōna ake āhuatanga o te tauira. Ā, he rerekē anō hoki te tukatuka rauemi mata o te pōro kowiri tira. Ā, he rerekē anō hoki te pakeke o ngā pōro kowiri tira nā runga i ngā āhuatanga rerekē.
(1) Rauemi:
① Rauemi DDQ (kounga tuhi hohonu): E pā ana ki te rauemi e whakamahia ana mō te tuhi hohonu (pokanoa), arā, ko te rauemi ngohengohe e kīia nei e tātou, ko ngā āhuatanga matua o tēnei rauemi ko te roa o te whakaroa (≧ 53%), te pakeke iti (≦ 170%), te kōeke o roto o te witi i waenga i te 7.0 ~ 8.0, me te mahi tuhi hohonu pai rawa atu. I tēnei wā, he maha ngā umanga e hanga ana i ngā pounamu thermos me ngā POTS, ko te ōwehenga tukatuka o ā rātou hua (RAHI PĀNUI/diameter hua) he teitei te nuinga, ā, ko te ōwehenga tukatuka he 3.0, 1.96, 2.13, me te 1.98. Ko ngā rauemi SUS304 DDQ te nuinga e whakamahia ana mō ēnei hua e hiahia ana ki te ōwehenga tukatuka teitei ake, ko te tikanga, ko ngā hua he ōwehenga tukatuka neke atu i te 2.0 me whakaoti i muri i ētahi wā. Mena kāore e taea te toro atu ki ngā rauemi mata, ka ngāwari te puta o te pakaru me te kukume i roto i te tukatuka o ngā hua kua hohonu te kume, ka pā ki te reiti tohu o ngā hua kua oti, ā, ka piki ake te utu o ngā kaihanga;
② Ngā rauemi whānui: E whakamahia ana mō ngā rauemi ehara i te DDQ, he iti te roa o te whakaroa o tēnei rauemi (≧ 45%), he teitei te pakeke (≦180), he iti te rahi o te kōhao o roto i waenga i te 8.0 me te 9.0, ki te whakaritea ki ngā rauemi DDQ, he ngoikore te kaha o te kukume hōhonu, ā, e whakamahia ana mō ngā hua ka taea te tiki me te kore e totoro. Pērā i te momo taputapu kai, te pūnu, te marau, ngā taputapu hiko, te whakamahi paipa maitai. Heoi, he painga tōna ki te whakataurite ki ngā rauemi DDQ, arā, he pai te āhuatanga BQ, nā te mea he paku teitei ake te pakeke.
