Ko te whakarewanga haumi (te whakarewa wake kua ngaro) he tikanga mo te mahi whakarewa tika ka taea te whakaputa i nga taipitopito ahua tata-kupenga ma te whakamahi i nga tauira ware pi. Ko te whakarewanga haumi, te ware pi ngaro ranei he tikanga hanga whakarewa e whakamahi ana i te tauira ware pi e karapotia ana e te anga uku hei hanga i te maaka uku. Ka maroke te anga, ka rewa te ware pi, ka waiho ko te maaka anake. Na ka hangaia te waahanga whakarewa ma te ringihanga i te whakarewa whakarewa ki roto i te maaka uku.
E ai ki nga momo herenga mo te hanga anga, ka taea te wehea te makanga haumi ki te makanga haumitanga sol sol binder, te whakarewanga whakangao mo te karaihe wai me te makanga haumi me o raatau ranunga hei taonga here.
Ko te karaehe wai, e mohiotia ana ko te Sodium Silicate, he ahua o te wairewa alkali alkali silicate, he karaihe i roto i te ahua totoka me te hanga i te otinga karaihe wai ka rewa ki te wai. E ai ki te rereketanga o nga konganuku alkali kei roto, e rua nga momo karaihe wai pāhare me te karaihe wai houra. He ngawari te wairewa i roto i te wai, he iti ake nga poke, he pai te mahi. Na reira, ko te karaihe wai mo te makanga haumi he karaihe wai konutai, ara Na20·mSiO2, He wairewa wai colloidal maramara, translucent ranei i hangaia i muri i te waiwai. Ko nga waahanga matū matua o te karaihe wai ko te waikura silicon me te konutai waikura. I tua atu, kei roto ano he iti o nga poke. Ko te karaihe wai ehara i te puhui kotahi, engari he ranunga o nga puhui maha.
I roto i te tukanga makanga haumi, te here karaihe wai me te paninga he mahi pūmau, utu iti, huringa anga-hanga poto me te tono watea. Ko te mahinga anga karaihe wai e tika ana mo te hanga i nga whakangao haumi penei i te waro maitai, te rino-iti, te rino, te parahi me te konumohe he iti ake te kounga o te mata.
Ritenga koranu maitai maka miihini wahi e manawapa engaro te wax haumi makanga tukangame te karaihe wai (te wairewa wai o te konutai konutai) hei taonga here mo te hanga anga. Ko te kounga o te anga e whakaawe ana i te tika o nga whakarewanga whakamutunga, na reira he mahi tino nui i te wa e maka ana te haumi. Ko te kounga o te anga e hono tika ana ki te taratara me te rahinga o te whakaroa o te whakarewanga whakamutunga. Na reira, he mahi nui mo te whakangao whakangao haumi ki te whiriwhiri i tetahi tikanga hanga pai mo te anga pokepokea ai.E ai ki nga taapiri rereke me nga taonga here mo te hanga i te anga pokepokea, ka taea te wehea nga peeke whakangao haumi ki nga anga taapiri karaihe wai, nga anga piriti silica sol, nga anga taapiri ethyl silicate me nga anga hiato ethyl silicate-silica sol. Ko enei tikanga whakatauira ko nga tikanga e whakamahia nuitia ana i roto i te makanga haumi.
Anga pokepokea ma te karaihe wai (wairewa wai o te konutai konutai)
Ko te makanga haumitanga e mahia ana e te whakarewa anga karaihe wai he nui te taratara o te mata, he iti te tika o te ahu, he huringa hanga anga poto me te utu iti. Kei te whakamahia nuitia tenei tukanga ki te whakarewa i te rino waro, te rino koranu iti, te konumohe konumohe me te konumohe parahi.
Mold Shell na Silica Sol Shell (he marara o nga matūriki silica tauine nano i roto i te wai whakarewa ranei)
He iti te taratara, te tika o te ahu, me te huringa hanga anga roa. Kei te whakamahia nuitia tenei mahinga i roto i te wera o te wera wera, te whakarewa i te wera wera, te whakarewa rino, te whakarewa waro, te whakarewa iti, te whakarewa konumohe me te whakarewa parahi.
Mold Shell by Ethyl Silicate Shell
I roto i te whakangao haumi, ko nga whakarewanga i mahia ma te whakamahi i te ethyl silicate hei here kia iti ai te taratara o te mata, te tika o te ahu, me te huringa hanga anga roa. Ka whakamahia nuitia tenei tukanga i roto i te whakarewatanga o te wera-wera, te whakarewa i te wera-wera, te whakarewa rino, te whakarewa waro, te whakarewa iti, te whakarewa konumohe me te whakarewa parahi.
Ka whakamahia te maitai waro, te rino koranu iti, me te whakarewa taputapu i roto i te tinitono ahumahime nga taiao. Na te maha o nga tohu, te maitai me o ratou koranu ka taea te whakamahana-wera hei whakapai ake i te tukunga me te kaha o te kaha; me te whakatika i te pakeke me te ngawari ki nga hiahia tono a te miihini, ki nga taonga miihini ranei e hiahiatia ana.
Ko nga whakarewanga whakangao rino koranu-aatete ki te kakahu ko nga waahanga whakarewa i mahia e te tukanga whakarewanga haumi ware pi ngaro i mahia mai i te rino koranu kakahu-atete. I te RMC Foundry, ko nga tikanga nui o te whakarewa kirikiri ka taea e matou te whakamahi mo te rino koranu kakahu-aukati ko te whakarewa kirikiri matomato, te whakarewa kirikiri whakakikoruatia te kapia, te whakarewa kirikiri kore-tunu, te whakarewa pahuka i ngaro, te whakarewanga korehau me te makanga haumi. Ko te maimoatanga wera, te maimoatanga mata me te miihini CNC e waatea ana i to maatau wheketere kia rite ki o tuhi me o whakaritenga.
I roto i te tini o nga momo whakarewa whakarewa, ko te rino whakarewa he tino whakamahia te rino whakarewa. Ko te rino whakarewa-aukati te nuinga ka whakapai ake i te aukati kakahu o nga whakarewa rino ma te taapiri i nga mea rereke o nga mea whakauru, penei i te konupora, chromium, waro, me etahi atu, ki te koranu. I te wa ano, ko te whakamarumaru o nga kakahu rino-aukati i runga i te tikanga maimoatanga wera e whakamahia ana e te raima me te hanganga o te whakarewanga.
E ai ki nga ahuatanga kakahu rereke, ka taea te wehewehe i te kakahu o te whakarewanga rino ki te kakahu abrasive, te kakahu piri, te kakahu ngenge, te kakahu pirau me te kakahu pouri. Ka whakamahia te nuinga o te whakarewanga rino i roto i nga mara ahumahi me nga tikanga mahi uaua me nga whakaritenga mahi miihini teitei, penei i te maina, te whakarewa, te hanga, te mana, te petrochemical, te tiaki wai, te ahuwhenua me nga umanga kawe. Ka whakamahia te nuinga o nga whakarewanga rino-aukati i roto i nga ahuatanga abrasion me etahi kawenga paanga, penei i nga taputapu huri, nga kaitarai, nga kuru, nga tarakihana, me era atu.
