Taura muka whatu GYTS 48, he turanga ārai tika kua tanumia mō te whakamahinga o waho

Ko te taura whatu GYTS, he mea huna tika, he 48-matua, he taura whakawhitiwhiti kōrero me te tere tuku tata ki te mārama. Ko te hanganga taura whatu GYTS he mea hanga ki te muka aratau-kotahi 9/125 μm, ki te muka aratau-maha 50/125 μm, 62.5/125 μm rānei, i roto i te ngongo wetewete i hangaia ki te rauemi ārai-wai kounga teitei. Kua whakakīia tēnei ngongo wetewete ki te rauemi hiato ārai-wai. Ko te pokapū o te matua taura he matua whakapakari whakarewa. Mō ngā taura whatu maha-matua, me whai paparanga koti PE anō te matua whakapakari. Ka takaihia te ngongo wetewete me te waea whakakī ki te matua whakapakari pokapū hei hanga i te matua taura porowhita kiato. Ka whakakīia ngā āputa i roto i te matua taura ki ngā whakakī ārai-wai. Ka takaihia te rīpene maitai takai-rua (PSP) ki te taha roa, kātahi ka tukuna ki roto i te taura me te koti polyethylene.

1. Mā te roa o te muka tika ka pai te mahi ā-pūkaha me te pāmahana
2. Mā te ngongo wetewete kaha-teitei e ātete ana ki te waikura me te matū whakakī ngongo motuhake ka tiakina te muka.
3. He pai te hanganga kiato i hangaia mō te ārai i te mimiti o ngā ngongo wetewete.
4. Ko te mema kaha o waenganui e whakamahi ana i te waea maitai phosphated, i te FRP rānei me ngā moduli Young teitei.
5. Mā ngā ngongo wetekina me ngā āputa katoa o te matua taura kua whakakiia ki te matū ātete makuku me te aukati wai ka kore te wai e tomo whakaroa.
6. Mā te herenga roa o te rīpene maitai ki te uhi PE, ehara i te mea ka ārai noa i te makuku i te taha whakarara, engari ka whakapakari anō hoki i te ātete ki te kuru.
7. Ka taea e te uhi polyethylene, LSZH rānei o waho te ātete i te pirau mai i ngā hihi ultraviolet (UV).
