Whakaahuatanga:
He taputapu matua te reti waikura TEG i roto i te purenga hau māori, i te maimoatanga hau māori rānei. Ko te reti waikura TEG o te hau whāngai he purenga hau māori mākū, ā, ko te kaha o te waeine he 2.5~50×104 Ko te ngāwari o te mahi he 50-100%, ā, ko te wā whakaputa ia tau he 8000 hāora.
Ko te paheke maroke TEG e whakamahi ana i te 99.74% (wt) triethylene glycol (kaihoko whakamaroke TEG), hei tango i te wai tino mākū i roto i te purenga hau māori mākū, ka purea mā te ngongo TEG i muri i te whakamaroke hau maroke (i roto i te āhua pēhanga tomairangi wai wheketere
tūtohi rere
I muri i te mimiti wai, ka hangaia anōtia te TEG mā te whakamahana me te whakahou i te ngongo ahi pēhanga hauātea. I muri i te whakawhiti wera, ka whakamataohia te wai kua pau te wera, ā, ka whakahokia ki te pourewa mimiti TEG i muri i te pēhanga hei hangarua.
Ko ngā wāhanga hanga hau e puta mai ana i te whakahoutanga o te wai momona he mamaoa wai te nuinga, ā, he iti noa iho ngā hauwaiwai me ngā hau kei roto.
Hei whakakore i ngā tūponotanga haumaru me te karo i ngā tukunga tika o te parahanga taiao, ka tukuna te hau para hangarua mai i te taputapu whakaora whanariki ki te āhuarangi i muri i te tahunga i roto i te oumu tahunga hau putanga.
Ngā Āhuatanga:
1. He māmā noa te tukanga whakamaroketanga TEG, he hangarau pakari, ki te whakaritea ki ētahi atu tikanga whakamaroketanga ka nui ake te maturuturunga o te tomairangi. He pai te pumau o te wera. He ngāwari ki te hanga anō, ā, he iti ngā mate, he iti te haumitanga me te utu whakahaere.
2. Kua tāutahia he whakawhiti wera wai kikokore/whai rawa i mua i te papu tohanga wai kikokore, e kore e whakapai ake i ngā āhuatanga mahi o te papu tohanga anake, engari ka whakanui ake hoki i te pāmahana o te wai whai rawa TEG ki roto i te kaiwhakaora triethylene glycol, ka whakahokia mai he wāhanga o te wera me te whakaiti i te whakamahinga o te hau wahie mō te whakaora.
3. Whakatakotoria he tātari ki te awa wai whai rawa hei tango i ngā poke miihini me ngā hua pirau e mau ana i roto i te pūnaha otinga, hei pupuri i te otinga kia ma, hei ārai hoki i te huka o te otinga, ka taea ai te whakaiti i te ngaronga o te whakarewa, ā, he pai hoki mō te mahi pumau mō te wā roa o te taputapu. Ko te tikanga whakamahana ngongo ahi tika i whakamahia i roto i te whakahoutanga TEG he pakari, he pono, he ngāwari hoki ki te whakahaere.
