He momo karāhe motuhake te karāhe whatu, ko tētahi o ngā rauemi taketake nui mō te hanga taputapu whatu. He pai ōna āhuatanga whatu, he āhuatanga ā-tinana, ā-matū hoki, ā, he mea nui hoki i roto i ngā momo whakamahinga whatu.

He aha ngā momo karāhe whatu?

Ka taea te whakarōpū i te karāhe whatu ki ngā momo rerekē i runga i ngā whakamahinga me ngā āhuatanga o te rauemi. Anei ētahi momo karāhe whatu e kitea whānuitia ana:

1. Karāhe silicate

Ko te karāhe silicate te momo karāhe whatu tino noa, ā, ko tōna wāhanga matua ko te silicate, arā, ko te silicon dioxide, kei roto i te nuinga o te wā ngā wāhanga pēnei i te boron oxide, te sodium oxide, me te magnesium oxide.

2. Karāhe mata

Ko te karāhe mata e pā ana ki te karāhe whatu kua tāpirihia he ōwehenga motuhake o te waikura mata, he nui te taupū whakaata me te kiato, ā, he maha ngā wā e whakamahia ana i roto i ngā taputapu whatu pēnei i ngā karu tiro me ngā karu hiko.

3. Karāhe borosilicate

Ko te nuinga o te wā, ka tāpirihia te waikura boron ki te karāhe borosilicate, he nui te taupū whakaata me te iti o te mahi marara, ā, e whakamahia whānuitia ana i roto i te hanga karaihe me ngā porotiti.

Ngā momo karaihe whatu

4. Karāhe kuata

Ko te wāhanga matua o te karāhe kuata ko te hauhā silicon, he tino pai ngā āhuatanga whatu me te pumau matū, ā, e whakamahia whānuitia ana i ēnei rā i roto i ngā taputapu whatu me ngā taputapu.

5. Karāhe whenua onge

Ko te karāhe whenua onge he karāhe whatu i hangaia mā te tāpiri i ngā huānga whenua onge, ka taea te whakarerekē i ngā āhuatanga whatu, ā, e whakamahia whānuitia ana i roto i te hanga i ngā mara hangarau teitei pēnei i te taiaho.

Te rerekētanga i waenga i te karāhe whatu me te karāhe noa

Ki te whakatauritea ki te karāhe noa, he pai ake te kounga o te karāhe whatu, he ngaio ake hoki, e pā ana ki te parakore o te hanganga, te tukanga whakarite, te mahi whatu, me ētahi atu. Ko ngā rerekētanga matua ko:

Matotoru me te taumaha

He iti ake te matotoru o te karāhe whatu, he mama ake hoki te taumaha, ā, he pai mō te hanga taputapu whatu tino tika. Ka taea te hanga karāhe noa kia matotoru ake, kia taumaha ake hoki nā runga i ngā momo whakamahinga.

Wāhanga

He parakore ake te hanganga o te karāhe whatu, ā, he tino āta whakahaeretia, he mea hanga mā te whakamahi i ngā tauira matū motuhake me ngā rauemi mata tino parakore hei whakatutuki i ngā āhuatanga whatu e tumanakohia ana. He māmā ake te hanganga o te karāhe noa, he mea hanga mai i ngā silicates me ētahi atu poke.

Te hanganga o te karāhe noa

Te tukanga whakarite

Me tino tika ngā tukanga whakarite mō te karāhe whatu, me te whakamahi i ngā tukanga pēnei i te rewa pāmahana teitei, te maimoatanga wera korehau, me te whakamatao tika kia mau tonu ai te pumau me te tika o te mahi whatu. Ko te tikanga, ka whakamahia e te karāhe noa ngā tukanga whakarite karāhe tuku iho, ā, he iti noa te utu whakaputa.

Mahi whatu

He nui ake ngā āhuatanga o te karāhe whatu, he iti ake te horapa, he iti ake te mimiti mārama, ā, he tino pai te mahi whatu. Nō reira, ka taea te whakamahi whānui i te karāhe whatu i roto i ngā taputapu whatu pērā i ngā karāhe arotahi, ngā porotiti, me ngā tātari whatu mō ngā pūnaha whatu tino tika.

Heoi, he ngoikore te mahi whatu o te karāhe noa, ā, e whakamahia whānuitia ana i roto i ngā mara pēnei i ngā ipu noa me ngā rauemi hanga.
