1. Rauemi whakakoi
(1)Ko te whakapūmau i te maitai waro me te maitai iti-koranu kei roto ko te whakapūmau ngohengohe me te whakapūmau mārō. Ko te tūhono e whakamahia whānuitia ana i roto i te whakapūmau ngohengohe ko te tūhono mata tine. Ka piki ake te makuku o tēnei tūhono ki te maitai i te pikinga ake o te ihirangi tine, nō reira me whakamahi te tūhono he nui te ihirangi tine hei hiri i ngā hononga. Ka taea te hanga i te paparanga matū whakarewa Fesn2 i te hononga i waenga i te tine me te maitai i roto i te tūhono mata tine. Hei karo i te hanganga o te matū i roto i tēnei paparanga, me whakahaere tika te pāmahana tūhono me te wā pupuri. Ko te kaha kutikuti o ngā hononga maitai waro i whakapūmauhia ki ētahi tūhono mata tine noa e whakaaturia ana i te Ripanga 1. I roto i ēnei, ko te kaha hononga i whakapūmauhia ki te 50% w (SN) te mea teitei rawa, ā, ko te kaha hononga i whakapūmauhia ki te tūhono kore-antimony he teitei ake i te mea i whakapūmauhia ki te antimony.

I te wā e whakakanapahia ana te maitai waro me te maitai koranu iti, ko te parahi parakore, te parahi konutea me te parahi hiriwa konutea ngā konganuku whakakī e whakamahia ana. He teitei te ira rewa o te parahi parakore, ā, he ngāwari ki te waikura i te konganuku turanga i te wā e whakakanapahia ana. Ko te nuinga o te wā e whakamahia ana mō te whakakanapahia he pare hau me te whakakanapahia korehau. Heoi, me mōhio ko te āputa i waenga i ngā hononga kua whakakanapahia me iti iho i te 0.05mm hei karo i te raruraru kāore e taea te whakakī i te āputa hononga nā te pai o te rere o te parahi. He kaha teitei ngā hononga maitai waro me te maitai koranu iti kua whakakanapahia ki te parahi parakore. Ko te tikanga, ko te kaha kutikuti he 150 ~ 215mpa, ko te kaha kume ka tohatohahia i waenga i te 170 ~ 340mpa.
Ki te whakataurite ki te parahi parakore, ka heke te ira rewa o te tūhono parahi konutea nā te tāpiri o te Zn. Hei ārai i te mimiti o te Zn i te wā e whakakanapahia ana, i tetahi taha, ka taea te tāpiri i te iti o te Si ki te tūhono parahi konutea; i tetahi atu taha, me whakamahi ngā tikanga whakamahana tere, pērā i te whakakanapahia mura, te whakakanapahia whakaawe me te whakakanapahia tuku. He pai te kaha me te kirihou o ngā hononga o te maitai waro me te maitai koranu iti i whakakanapahia ki te konganuku whakakī parahi konutea. Hei tauira, ko te kaha kume me te kaha kutikuti o ngā hononga maitai waro i whakakanapahia ki te tūhono b-cu62zn ka eke ki te 420MPa me te 290mpa. He iti ake te ira rewa o te tūhono teihana parahi hiriwa i tērā o te tūhono parahi konutea, he mea watea mō te whakarewa ngira. He pai tēnei konganuku whakakī mō te whakakanapahia mura, te whakakanapahia whakaawe me te whakakanapahia oumu o te maitai waro me te maitai koranu iti, engari me whakaiti te nui o te Zn i te wā e whakakanapahia oumu ana, me te whakanui ake i te tere whakamahana. Ka taea e te whakakanapahia te maitai waro me te maitai koranu iti me te konganuku whakakī parahi konutea hiriwa te whiwhi hononga me te kaha me te kirihou pai. Kei te Ripanga 2 ngā raraunga motuhake.

(2) Rerenga: me whakamahi te rere, te hau ārai rānei mō te whakakanapa i te maitai waro me te maitai iti-koranu. Ko te tikanga ka whakatauhia te rere mā te whakarewa whakakī kua tohua me te tikanga whakakanapa. Ina whakamahia te tūhono tine mata, ka taea te whakamahi i te wai whakaranu o te konutea pūhaumāota me te haukinia pūhaumāota hei rere, hei rere motuhake rānei. Ko te toenga o tēnei rere he tino waikura, ā, me horoi rawa te hononga i muri i te whakakanapa.
I te wā e whakakīia ana ki te konganuku whakakī parahi konutea, me whiriwhiri te rerenga fb301, fb302 rānei, arā, te borax, te ranunga borax me te waikawa boric rānei; i te whakakīia mura, ka taea hoki te whakamahi i te ranunga methyl borate me te waikawa formic hei rerenga whakakī, ka whakamahia te kohu B2O3 hei tango kiriata.
Ina whakamahia te konganuku whakakī whakakī parahi hiriwa me te konutea, ka taea te whiriwhiri i ngā rerenga whakakī fb102, fb103 me te fb104, arā, te ranunga o te borax, te waikawa boric me ētahi fluoride. He waikura te toenga o tēnei rerenga ki tētahi taumata, ā, me tango atu i muri i te whakakī.
2. Hangarau whakapūmau
Me horoi te mata e whakarewahia ana mā te whakamahi i ngā tikanga ā-ringa, ā-matū rānei, kia tino tangohia te kiriata waikura me ngā mea rauropi. Kaua te mata kua horoia e tino taratara, ā, kaua hoki e piri ki ngā maramara whakarewa, ki ētahi atu paru rānei.
Ka taea te whakawera i te maitai waro me te maitai iti-koranu mā roto i ngā tikanga whakawera noa. I te wā e whakawera ana i te mura, me whakamahi te mura koretake, te mura whakaiti-iti rānei. I te wā e mahi ana, me karo te whakamahana tika i te konganuku whakakī me te rere mā te mura i ngā wā katoa e taea ana. He tino pai ngā tikanga whakamahana tere pēnei i te whakawera whakapūmau me te whakawera tuku mō te whakawera i te maitai kua tineihia me te maitai kua whakamaroketia. I taua wā anō, me whiriwhiri te tinei, te whakawera rānei i te pāmahana iti iho i te whakamaroketia hei ārai i te ngohengohe o te konganuku turanga. I te wā e whakawera ana i te maitai iti-koranu kaha teitei i roto i te hau tiaki, ehara i te mea ko te parakore teitei anake te mea e hiahiatia ana, engari me whakamahi hoki i te rere hau hei whakarite i te makuku me te horapa o te konganuku whakakī ki runga i te mata o te konganuku turanga.
Ka taea te tango i te rerenga toenga mā te whakamahi i ngā tikanga matū, ā-ringa rānei. Ka taea te muru, te horoi rānei i te toenga o te rerenga whakakoi waro ki te penehīni, te waipiro, te acetone me ētahi atu whakarewa waro; me whakakore tuatahi ngā toenga o te rerenga waikura kaha pērā i te konutea pūhaumāota me te ammonia pūhaumāota ki te wairewa NaOH, kātahi ka horoia ki te wai wera me te wai matao; he uaua ki te tango i ngā toenga waikawa boric me te waikawa boric, ā, ka taea anake te whakaoti mā te whakamahi i ngā tikanga ā-ringa, mā te rumaki roa rānei ki te wai e piki haere ana.
