Ko te ira whakakoero o hiriwa

Mai nga wa onamata, mohiotia iwi hoki ma whakarewa pīataata. Silver (Ag) kua whānui whakamahia rite he rauemi mō ngā whakapaipai. Ko tōna āhuatanga i te pānga ringihia tono i roto i te rangatira tonu mo te hanga o oko whare.

hiriwa Pure - tino ngohengohe me te rauemi kōngohe. Ko te āhua o te hanganga karaihe o te pae kupenga hiriwa e te ahua o te orapa ki taha ki pokapū. O karamu o te whakarewa e taea te totoro rua-kiromita waea angiangi. Ko te kiato nui (10.5 g / cm3) taea te hiriwa, he mea pauna whakataetae ki mata. Otiia i runga i taua 'ulungaanga rite kawe ia hiko, me te ngāwhā, mo te hiriwa e kore e whai whakataetae. te tahu koko hiriwa i roto i te karaihe o te wai kohua te ki tere maere, me te whakamahi o te kōrero hiriwa (waea, hoapā, terminals) i roto i te hanga o ngā reo irirangi whakaatu ratou kounga teitei, me ngā āhuatanga hangarau faahiahia.

Ko te ira whakakoero o hiriwa i 962 ° C whakahaere tona whāwhā. alloys hiriwa ki konganuku rerekē kua whakamahia whānuitia i roto i ngā mara. hanga te tua iti o te parahi i roto i tona hanganga te whakarewa uaua me atu e manakohia mo te hanga o te momo o ngā hua.

Ko te ira whakakoero o te hiriwa, ko te kore anake nui i roto i tona whakamahi, engari ano hoki production. I tua atu, hoki me te whakarewa i te vyplavlivaniem ore i reira e he maha o ngā tikanga matū o te tangohanga pērā i cyanidation me te whakakotahitanga.

I whakaritea oxidized i roto i te rangi, Ko te ahei o tātau buka nui o hau hiriwa. Ahakoa i roto i te āhua totoka te hana reira ki 450 ° C, kua reira te kaha ki te takanga mai i te nui o te hāora i roto i te i te taikaha o te rima nga wa tona rahi. Hoki hiriwa i roto i te āhua wai, faarahi tenei ahua ki 20 buka. E matau te pāmahana i te mea ngāwari te hiriwa ki te whakaputa uri i roto i te taiwhanga tautuhinga ataahua, engari wheako kino. Meangiti ohorere tinana tīmata ki te tikanga rerekē. Te hāora mawhiti wawahi te solidifying kirinuku i runga i te mata hiriwa ki te ope nui, te whakaputa pānga spattering māhorahora.

I te tīmatanga, i tenei whakarewa he uara rite rauemi mō te rei. ahua ātaahua, noho pai o te tukatuka, plasticity faahiahia me te ira whakakoero iti o te hiriwa me ona āhuatanga rongoa kua hanga hua i tenei whakapakoko whakarewa mo whakapaipai hauora. rei Modern, ki te kahore hoki te huinga o te hiriwa ki te kohatu utu nui, kua ako ki te mahi i runga i tona koura mata nōhia te. Ko te hangarau o te tukanga e ki pūkete te pāmahana i i rewa Gold (1064 ° C) me te ki e te hiriwa (962 ° C). Mā te whakamahi i te huinga uaua kitea, utu ratou a te whakahaere ki te whakatutuki i ngā hua o te kounga kairangi te kaituhi kohatu ariki i te raro.

Ko te whakamahi o tenei whakarewa i roto i te toi e hāngai ana i runga i te tahi atu, āhuatanga rite ataahua atu i te ukanga me te ira whakakoero āhua iti o te hiriwa. I te ata o te hikohiko engineering hiriwa kaha whakamahia i roto i ngā kōrero reo irirangi. Ko te tikanga, ko te kounga, me te tika o taua whakaaro he whakaritenga motuhake. Maoro, i reira ko tetahi displacement nui o hiriwa i roto i te whakamahi o ngā rauemi hou.

kitea Ddlya hiriwa mahi i roto i te kiriata, me te whakaahua. Tuatahi ike - whakawhitihia ngongo i roto i te pouaka whakaata - hoki e kore i waho te whakamahi o te hiriwa.

Te whakamahi whānui i roto i te hou hiriwa taputapu e kore he rite te pēne pai o nāianei hiko, me rite te taonga ki te mahi ringihia ahurei. whiriwhiringa Various, wahi mo te taputapu hauora, kua hanga mīhini horoi me refrigerators te whakamahi i pūhui hiriwa. Ki ngā katote tenei otinga hangarau mahi matū i roto i te whakahaere i tona mahi rongoā horoi.

Hiriwa e tika ana ki ona āhuatanga ahurei, Kei te whānui whakamahia i roto i ngā rāngai o te mahi a te tangata. Timata tona kōrero ki te whakapaipai, kua tito reira o ngā pūrere hangarau matatini kua i roto i te wāhi. riro te reira i te rōpū ki te ahunga whakamua pūtaiao, me te hangarau, te kimi tono i roto i te whānuitanga o ngā hua irirangi momo. Na te reira e mātaki kata me te karanga, me mātaki pikitia tuatahi. Na rawa, kua reira i whakamahia i roto i te taputapu whare rite te taputapu kaha mo te horoi me te disinfection.
