Ko te pakeke-pakeke te kowiri tira kowiri tira
Whakaahuatanga poto:
Ko te pakeke tonu, e mohiotia ana hoki ko te whakamarumaru i te whakamarumaru, ko te kaha o te kaha me te uaua o te pakeke o te pakeke. te whakapakari i te rauemi.
Te pakeke-pakeke ki te whakakore i te kowiri tira:
Ko nga waahanga whakarewa he tohu mo te mahi murua, i te wa e mahana ai te taonga, ka pania ranei ki te kohukohu. , Te hinu me te hau, a ka warewarehia te pai o te pai o te whakarewa, he ahua tika, he rite tonu, he rite tonu te ahua o te paera Kei te hiahiatia, penei i te hanganga o nga hanganga, i te mea raanei ranei mo te tukatuka taapiri.

He aha te ua e whakaohooho ana i te kowiri tira?
Whakanuia te whakamamae i te kowiri tira, he maha tonu te tohu "pH kore he kowiri tira," he momo o te kowiri tira, ka raru te whakamarumaru, te pakeke ranei. Ko tenei mahinga ka whakarei ake i nga taonga miihini o te rauemi, otira ko tona kaha me te uaua. Ko te rerenga tino nui ka whakapakeke i te kowiri tira17-4 ph(Astm A705 Farde 630), engari ko etahi atu tohu, penei i te PH me te 13-8 ph me te 13-8 ph me te 13-8 propensing stanys he chromium, nickel, me etahi atu konumohe. Ko te taapiri o enei waahanga taapiri e whakatairanga ana i te hanganga o te paheketanga i te waa maimoatanga wera.
He pehea te uaua o te ua kowiri?
Ko te pakeke ka raru te kowiri tira ko te tikanga e toru nga waahanga. I te tuatahi, ka raru te rauemi i te maimoatanga rongoa tino nui, i reira ka rewa nga ngota, te hanga i tetahi otinga kotahi-waahanga. Ka arahi tenei ki te hanganga o te maha o nga tohu karihi maha ranei "nga rohe" i runga i te whakarewa. I muri mai, ka puta te whakamarumaru tere i tua atu o te whakataunga whakarewa, te hanga i te otinga totoka i roto i te ahua metastable. Ka mau tonu te rauemi i roto i tenei kawanatanga tae noa ki te whakapakeke i te whakapakeketanga. Ko te pakeke o te pakeke ka hiahiatia te hanganga o te ao ki roto i te rohe whakaraerae, me whakarite te kaha o te mahi.
He aha nga momo rereketanga o te ua?
Ko nga tipu o te ua-whakapakeke i roto i nga momo, ia tangata ki te whakatutuki i nga whakaritenga me nga whakaritenga tono. Ko nga momo noa ko te 17-4 pH, 15-5 ph, 13-8 pH, 17-7 pH, A-286, Ritenga 450 (Ritenga 630 (Ritenga 63017-4 phMod), me te whakairo ritenga 455 Ko te kowhiringa o te rino e rere ana i runga i nga mea e pa ana ki nga ahuatanga penei i te taiao tono, nga mahi taputapu, me nga whakaritenga hangahanga.
