Ko te tikanga o nga taputapu waea tarai: iti waro waro maitai, waea piauau hiko, waea piauau wera wera, waea whakakikorua PVC kirihou.

Tauira whakamahia noa: 12#x14# 14#x14# ruaTauira kore-tikanga: Whakakikorua wera: 8# -- 36# (3.8mm -- 0.19mm)Whakakikoruatia: 8# -- 38# (3.8mm -- 0.19mm) I tua atu i te rahi o te waea, ka wehea te waea matua ki te waea tarai kotahi, te waea takirua takirua, me te waea e toru, te waea nematode e wha nga tataramoa.Miihini waea tarai-aunoa he miro, he whiri, he pakari, he ataahua.Te tukanga maimoatanga: te whakakikorua (te whakakikorua makariri) te waea taratara, te waea piauau wera wera, te waea taraihia.Ka hono te waea tarai ki te pou me te matiti wehe waea.

na ka taea e ia te whakatutuki i te painga whakamarumaru pai. E tika ana ki te mahi pickling o te waea maitai i mua i te mutunga o te hua

waea maitai oti, te tikanga e pā ana ki te maimoatanga wera whakamutunga o waea maitai.

(1) te mahi piiki i runga i te paparanga muddle kotakota.Ko te rere o te tukanga.

Waea rino wera -- → tiki -- → horoi wai, horoi wai pehanga teitei -- → whakapiri kotakota dipgrease -- → marokeKei te whakamahia nuitia tenei mahi tiki i roto i te tuhi o te waea waro maitai me te waea waro rino reo.

(2) Ko te mahi kohi i runga i te paninga konukura sulfate.Ko te rere o te tukanga e whai ake nei:

Waea rino whakawera -- → tiki -- → horoi wai -- → rumaki konukura sulfate -- → horoi -- → whakakore -- → whakamaroke

He pai tenei tukanga mo te tuhi waea waro waro whanui, waea waro waro reo whanui me te waea rino puna noa, engari kaore e pai mo te waea rino piauau.

(3) Ko te mahi piiki i runga i te paninga phosphating he penei e whai ake nei te waea rino kua whakamahana wera -- → pickling -- → horoi, horoi -- → paparanga phosphating rumaki -- → horoi, horoi -- → saponification -- → whakamaroke

Ka taea e tenei tukanga tiki he mata tuhi pai, he pai mo te waea waro waro maitai me te tuhi waea rino puna kaha teitei.Ko te matotoru o te paparanga phosphating e whakawhirinaki ana ki te paahi tuhi.
