Mekameka hononga waenga DIN764 kua whakarewahia
He mea hanga ngā mekameka hononga waenga DIN 764 ki ngā paerewa o te ao, ā, e whakamahia ana i roto i ngā momo ahumahi, he tino pai mō te mahi ahuwhenua me ngā mekameka here. Ko ngā mekameka maitai hononga porowhita DIN764 he reanga 2, reanga 3, me te reanga 5. Ahakoa kāore i hangaia, i hangaia hoki mō ngā kaupapa hiki, me whakatikatika me te whakamātautau. E rua ngā momo manawanui o ngā mekameka DIN 764: Akomanga A, e whakamahia ana me ngā wira mekameka; Akomanga B, e whakamahia ana me ngā roera. Ko te mutunga o ngā mekameka DIN764 ka taea te peita pango, te whakakikorua konutea, te whakakikorua wera, me ētahi atu.
Painga: Kei te wātea he tauira (Hei tirotiro i te kounga), Hoahoa ritenga (tānga waitohu), Ngā takai rerekē (pēke jute, wira kirihou, pahu rino, pouaka rakau), Wā arahi poto, Tikanga utu maha (T/T, LC, Paypal, Alipay).
Tau Tauira: DIN764

Ngā Whakatūpato:
Kaua ngā mekameka e whakamahia ki ngā taura mekameka.
Kaua rawa e whakamahia te taumaha rawa.
1: TE HANGA: Me tirotiro te āhua o te hononga me te kōhao V i te wā katoa o te tukanga. Me tirotiro hoki ngā inenga.
2: TE WHAKAWERA: I hangaia te whakarewa mā te whakamahi i ngā tukanga ātete, ā, i whakanohoia ki waenganui o tētahi waewae o te hononga. I oti pai te whakaoti puta noa. Kaua ngā hononga me ngā whakarewa e whakaatu i ngā pakaru, i ngā kohao, i ngā hapa rite rānei e kino ai te mekameka i muri i te whakarewa. Ko te whānui o te rauemi i te whakarewa kāore i neke ake i ngā whakaritenga o ngā rahinga, ā, kaua hoki e iti iho i te whānui o te rauemi o te hononga. Mō te mekameka maeneene kua whakarewahia, ka tangohia ngā tara i puta mai i te whakarewa, ā, ka oti pai te whakarewa puta noa. Mā te whakanoho o te whakarewa ki waenganui o te oko tika me ngā ātete i whakatakotoria ki ngā kokiritanga i te whakarewa ka whakaratohia ngā āputa e hiahiatia ana.
3: WHAKATAURITE: Me tirotiro te ine mō ia whakatauretetanga. Me tuhi te kawenga taunakitanga mō te whakatauretetanga mō ia puranga.
4:TOHU: Mīhini Whakatikatika Mekameka. Kei te wātea ngā raupapa tō mō te tohu/tā mekameka 5mm ki te 16mm. Kotahi te tīmatanga matua. Whakamahia te pūnaha whakahaere PCC me te mahi aukati aunoa ina tūpono he hapa, He hoahoa pokepokea whaitake. Tāpirihia te mahi taumaha-ake mō te mīhini hei whakanui ake i te pumau o te mahi.
He pūnaha tohu hau e taea ai te tohu i ngā hononga e rua i te wā kotahi.

Ko ngā tikanga whakamahana he rite te whai huatanga ki te pāmahana 400°C i puritia mō te wā 1 hāora. I te wā i whakaarohia ai kia manatokohia, ka whakamatautauria ngā mekameka tauira i muri i te whakamahanatanga anō me te pupuri mō te 1 hāora i te 400°C, kātahi ka whakamatao ki te pāmahana rūma. (I hiahiatia e AS 2321:2014 kia whakamahanahia te mekameka ki te pāmahana 200°C neke atu rānei mō te V200 me te 380°C mō te V400).
