1. He aha i tika ai kia rere tonu te pūhikohiko mō te iti rawa o te 5 meneti, ā, kia mutu mō te iti rawa o te 3 meneti i muri i te whakawetonga i mua i te tīmatanga anō?
Ko te whakamutu mō te iti rawa 3 meneti i muri i te whakaweto i mua i te tīmatanga anō he whakakore i te rerekētanga pēhanga i waenga i te tomokanga me te putanga hau o te pūwero. Nā te mea ina nui te rerekētanga pēhanga, ka piki ake te taipana tīmatanga o te motuka, ka piki ake te iahiko ki tētahi taumata, ka whakahohehia te parepare, ā, kāore e taea e te pūwero te haere tonu.
2. Te whakaū i te tūranga o te hauhautanga whakakī fluorine
E toru ngā wāhi e taea ai te tāpiri i te hau mātao: te pūwhakamātao, te taha rokiroki wai o te pūwhakamātao, me te pūwhakapūhaumāota.
Ina tāpirihia he wai ki te wāhi penapena wai, ina tīmata te pūnaha, ka pā tonu te hauhautanga wai ki te rango, ka puta he ru wai i te pūwero, he mea tino kino ki te pūwero. I taua wā anō, i muri i te urunga tika o te hauhautanga wai ki te pūwero, ka piri pea ki te pito, ka puta he ārai tere me te ngoikore o te ngaohiko; waihoki, ka puta anō tēnei āhuatanga ina tāpirihia he wai ki te taha o te pūwero.
Mō te pūwhakamātao, nā te nui o te rahinga, ka taea e ia te penapena i te nui o te hauhautanga, ā, kāore he hua kino i te tīmatanga, ā, he tere, he haumaru hoki te tere whakakī; nō reira ko te tikanga whakakī wai i te pūwhakamātao te tikanga whānui.
3.. Ngā pana wera me ngā whakamahana mō te tahuritanga auau
Kāore ngā pana wera me ngā whakamahana e pā ana ki te waea o te pūwero, ā, kāore hoki e hono raupapa tika ana i roto i te ara iahiko pūwero.
Ka whakahaerehia e ngā pana wera te whakakā me te whakaweto o te ara iahiko whakahaere pūwero mā te rongo i te pāmahana o te taupoki pūwero.
Ko ngā whakamahana he huānga āhuatanga pāmahana kino e tukuna ana ngā tohu urupare ki te tukatuka iti. Kua whakauruhia mua he huinga ripanga pāmahana me te ātete ki roto i te tukatuka iti. Ka taea e ia uara ātete i inehia te whakaata i te pāmahana e rite ana i roto i te rorohiko iti. Hei whakamutunga, ka tutuki te pānga whakahaere pāmahana.
4. Te pāmahana takai o te motuka
Me noho ngā tikanga whakahaere i raro iho i te 127°C i te kawenga mōrahi.
Tikanga ine: I roto i te 3 hēkona i muri i te mutu o te pūhiko, whakamahia he piriti Wheatstone, he mita ohm rānei matihiko hei ine i te ātete matua o te takai, kātahi ka tatauhia kia rite ki te tātai e whai ake nei:
Te pāmahana takai t℃ = [R2(T1+234.5)/R1]－234.5
R2: ātete inehia; R1: ātete takai i te āhua makariri; T1: pāmahana mōtini makariri
Mena ka nui ake te pāmahana o te takai i ngā tikanga whakamahinga, ka puta pea ngā hapa e whai ake nei:
Ka tere ake te koroheketanga o te waea kua whakakikoruatia ki te enamel (ka wera te motuka);
Ka tere ake te koroheketanga o te waea here rauemi whakamarumaru me te pepa whakamarumaru (ka haurua te roa o te whakamarumaru mō ia pikinga pāmahana 10℃);
Te hekenga o te hinu nā te wera nui (ka heke te mahi whakahinuhinu)
