Te Konutai Whanawha me te Konutai Whanawha: He aha te rerekētanga?

I roto i te rāngai matū ahumahi, ko te tika o te whakaingoa te mea nui. Mā te rerekētanga o te reta kotahi, o te ngota hāora kotahi rānei, ka taea te whakarerekē katoa i te whanonga ngota o te matū, te āhua mōrearea, me te tono ahumahi. Ko tētahi o ngā āhuatanga tino whakapoauau mō ngā kaiwhakahaere hoko, ngā kaiwhakahaere ratonga, tae atu ki ngā kaihangarau tukanga taitamariki, ko ngā matū kore-waro e rua e whakamahia whānuitia ana: Konutai Whanawha (Na₂SO₄)me Konutai Whāwhā (Na₂SO₃).

Ahakoa te āhua ōrite o ō rāua ingoa, mā te tuku whakawhiti, te whakamahi rānei i te momo rerekētanga hē i roto i te hanganga ka pakaru pea ngā puranga whakaputa katoa. E whakamārama ana tēnei aratohu hangarau i ngā rerekētanga taketake o te hanganga, te matū, me te mahi i waenganui i ēnei matū mahi e rua.

1. Hanganga Matū me ngā Āhua Waikura

Ko te pūtake o te rerekētanga kei roto i ā rātou tātai matū me te āhua waikura o te ngota whanariki matua.

Konutai Wheat (Koira₂Nā reira₄):Ko te ingoa anō hoki o tēnei pūhui ko te Sodium Sulfate, he ngota whanariki tēnei e herea ana ki ngā ngota hāora e whā. I konei, kei roto te whanariki i tōna āhua waikura pumau teitei rawa atu (+6). Nā te mea kua waikura katoatia, he pumau te Sodium Sulfate i ngā matū, he kore mahi, ā, kāore e ngāwari te whai wāhi ki ngā tauhohenga redox (whakaiti-waikura) i raro i ngā tikanga tukatuka paerewa.

Konutai Whāwhā (Koira₂Nā reira₄):Kotahi te iti iho o te ngota hāora kei roto i tēnei pūhui, ā, kei roto ko te ngota whanariki e honoa ana ki ngā ngota hāora e toru. I roto i tēnei whirihoranga, kei te iti iho te āhua waikura o te whanariki (+4). Nā te mea kāore i tino waikuratia, ka mahi te Konutai Sulfite hei matū kaha. kaiwhakaitiHe kaha tōna hononga tūturu ki te hāora, ka huri tere hei konutai whanariki ina pāngia e ngā taiao waikura.

2. Ngā Whakamahinga Ahumahi: Whakakī Korekore me te Whakaiti Kaha

Nā te mea he rerekē rawa ngā mahi matū a ēnei matū, he rerekē rawa ō rātou tūranga puta noa i ngā ahumahi tukatuka.

Ngā Whakamahinga Matua o te Konutai Whanawha (Na₂Nā reira₄)

Nā tōna koretake matū, tōna kaha katote teitei, me tōna pumau wera, ka whakamahia te Konutai Ngawha hei matū ā-tinana, hei matū hanganga rānei, kaua hei matū tauhohe:

• Ngā Hopi Paura: He tino whai hua tēnei hei whakakī rere noa, hei ārai hoki i te whakapiripiri, e whakahaere ana i te matotoru me te mātotoru o te paura horoi me te kore e whakararuraru i ngā matū hohe.
• Te Hanga Karāhe: He mea whakakoi tēnei i roto i te karāhe rewa, e āwhina ana ki te tango i ngā mirumiru hau moroiti me te ārai i te hanganga o te paru i te wā e rewa ana i te pāmahana tiketike.
• Te Tae Kakahu: Ka whakamahia hei whakaōrite, ka whakaitihia ngā utu kino i runga i ngā papanga, kia taea ai e ngā tae te uru ōrite ki te miro me ngā muka hangai.

Ngā Whakamahinga Matua o te Konutai Sulfite (Na₂Nā reira₄)

Nā ōna āheinga ki te tango me te whakaiti i te hāora, ka whakamahia te Konutai Sulfite ki ngā wāhi e hiahiatia ana te wawaotanga matū:

• Te Maimoatanga Wai: E werohia whānuitia ana ki roto i ngā pūnaha wai whāngai pōro ahumahi hei tango hāora hei ārai i te waikura o roto me te pakaru o ngā paipa whakarewa.
• Te Ahumahi Penupenu me te Pepa: Ka whakamahia i roto i te taahiraa whakapūkara sulfonation o te penupenu matū-ā-ringa hei wawahi i ngā here lignin, kia puta ai he muka pepa kaha ake, kanapa ake.
• Te Tiaki Kai me te Waina: He mea patu huakita, he mea ārai mate hoki, ā, he ārai i te parauri o ngā whākōkī me te pirau o ngā huakita i roto i ngā hua me ngā inu maroke.

3. Ngā Āhuatanga Ā-tinana me ngā Rerekētanga Whakahaere

Ko ngā matū e rua e puta ana i te nuinga o te wā he paura tioata mā, he kirikiri rānei, ā, kāore e taea te tautuhi ā-kanohi. Heoi, ka rerekē ō rāua whanonga ā-tinana i roto i te wā:

• Konutai Whanawha he tino pumau i te rangi tuwhera. Kei te wātea mai i te āhua kore wai, i te āhua rānei he decahydrate (te tote o Glauber).
• Konutai Whāwhā ka puhoi te pirau i te wā e rongoatia ana mēnā ka pāngia e te hau me te makuku o te taiao, nā te mea ka āta mimiti i te hāora o te hau hei hanga i te konutai whanariki. Me rongoa ki roto i ngā ipu ārai-hau me ngā whakahaere iti o te makuku hei pupuri i tōna kaha matū.
