Ngā Tikanga Tango Waikura: Te Oro Ā-ringa me te Horoi Matū

 

Ngā peerahe wāhanga tino tika i roto i ngā taputapu mīhini. Ehara i te mea ka pā noa te waikura ki te tika o te mahi engari ka tere ake hoki te pakaru. Mā te patu matapo, te akiaki rānei i te waikura ka nui ake te kino. Me whakarite ngā tikanga whakatika pūtaiao ki te āhuatanga motuhake: e taunakihia ana te waikura māmā me te maimoatanga ā-ringa ātaahua, ko te waikura taumaha ia me horoi hohonu i ngā matū. Kei raro nei ētahi tikanga tango waikura whai hua me te whai hua.

 

1. Te Whakakanapa Ā-ringa: Te Whakatika Ngāwari, He Pai mō te Waikura Mata

Ina he iti noa te waikura, te ira rānei kei runga i tete whārikimā te oro ā-ringa ka taea te whakahoki mai i te mata kia maeneene, me te kore e whakamahia he matū kino.

 

Te Whakakanapa Tuatahi: Whakamahia he pepa kirikiri pai 000-kiriata, he kakahu emery ngohengohe rānei hei mirimiri ōrite i te wāhi waikura i te taha o tete whārikiara reihi, me te karo i te pēhanga nui rawa e rakuraku ai.

 

Te Whakakanapa Whakarōpū: Kōwhiria he matū whakakanapa i runga i te kaha o te waikura, ka neke haere mai i te matotoru ki te kikokore. Mō te waikura papaku, ka taea te whakamahi tika i tētahi matū whakakanapa kua oti te whakaoti.

 

Tohutoro mō te Whakapiri Whakakoi i Hangaia i te Kāinga: Ka taea e ngā kaiwhakamahi mātau te whakaranu i te chromium chloride, te sodium silicate, me te waikawa stearic i ngā ōwehenga tika hei hanga i tētahi reo whakakoi tino whai hua mō ngā hua whakakoi pai ake. He painga tēnei tikanga mō te whakahaere, ā, kāore e kino te papa, he mea tino pai mō te tiaki i ngā peera tino tika, i ngā wāhanga iti rānei.

 

 

2. Te Whakarewatanga Matū: Te Tango Waikura Kaha mō te Waikura Hōhonu

 

Ina matotoru, ina pūwero rānei te paparanga waikura, kāore e whai hua te whakakanapa ā-tinana, ā, he uaua hoki ki te tango katoa. Me whakamahi te tango waikura matū hei tango wawe i te waikura mā te tauhohenga wairewa.

 

Te Tukanga Whakahaere Paerewa:

 

Te horoi-mua: Ka tango i te hinu me ngā poke kia pai ai te pānga o te otinga matū e whai ake nei ki te mata whakarewa;

 

Horoi Wai Wera: Ka whakaara ake i te pāmahana o te rauemi mahi hei whakahaere i te mahi waikawa ōrite;

 

Te Whakamākūkū Piki: Ka whakamahia he otinga tango waikura kei roto ko te chromic anhydride, te waikawa phosphoric, te waikawa whanariki rānei, me ngā aukati waikura i tāpirihia hei tiaki i te konganuku turanga;

 

Whakahaere Pāmahana: Ka whakamahana i te wai whakapūkara ki te 60–95°C (i runga i te hanganga) hei whakanui ake i te tere o te tauhohenga;

 

Maimoatanga Whai Muri: Whai muri i te rumakina, ka horoia ki te wai matao, ka whakakore i te kawakore, ka whakakorengia te waikura hei ārai i te waikura, ā, ka hiritia te hinu hei ārai i te waikura tuarua.

 

Tohutohu Haumaru: He tino waikura ngā wai waikawa. Me mau tonu ngā taputapu tiaki i te wā e pā ana, e mahi ana hoki i roto i te taiao e pai ana te hau. Me whakakore te wai para i runga i ngā ture, ā, kaua e maka noa i te wai.

 

Ahakoa he oro ā-ringa ātaahua, he horoi matū whai hua rānei, ko te mea nui ko te whakamahi i te otinga tika mō te āhua tika. Mā te mōhio ki te whiriwhiri taputapu tika, ki te raupapa tukanga, me ngā tikanga haumaru, ka roa ake te ora o te peera, engari ka whakarite hoki i te mahi maeneene me te pono o ngā taputapu. I roto i te tiaki o ia rā, e taunakihia ana kia aro nui ki ngā tikanga iti te whakaekenga, ā, me whakamahi noa i ngā tikanga matū ina hiahiatia hei whakatutuki i ngā whāinga rua o te whakaora mahi me te tiaki rauemi.
