He Taapiri Taapiri Matao Me Te Toka Mo Te Anodizing
1. He pai te atete ki nga poke me te kaha ki te aukati i te waikawa me te alkali.
2. Ko te otinga he painga o te ngawari ki te whakahaere, te whānuitanga o nga tawhā tukanga, kaore he take ki te whakatika i te pH i nga wa katoa.
3. Aukati i te pupuhi hiri kia kore e puta.
4. I muri i te maimoatanga hiri, ka taea e ia te whakapai ake i te pakeke o te mata me te kanapa o nga tuhinga konumohe.
| Taapiri Hiri Matao | Te wai whakaheke |
| 5~5.5g/L | Taurite |

| 0.9~1.3g/L | 0.4~0.6g/L | 5.5~6.5 | 22~28 ℃ | 1μm/1.3min | 0.9~1.5kg/T |
1. Whakatauhia nga kukū o te Ni,F me te pH, hanga i roto i te awhe o nga tawhā tukanga
2. Whakaritea te pH ma te taapiri i te waikawa acettic dilute (waikawa waiwaiwai waimeha) me te waimeha konutai haukini (hamonia waimeha), pupuri i te uara pH i waenga i te 5.5 me te 6.5.
3. Mo te whakaiti i te parahanga o te otinga pati horoi, kia kaha te whakahaere i te kounga o te wai me te pH o te horoi horoi, kaua e iti iho i te 4.5 te pH.
Ko te Cold Sealing Additive he mea hiri ki te peeke, 5kg kupenga ia ia me nga peeke 4 ki te kaata, 20kg kupenga ia.Ka tiakina mai i te marama i te waahi maroke.
Te whakatau i te ihirangi nickel katote (Ni2+).
1. Nga mahi whakamatautau.
Toia tika te 10mL o te wai totohu ki roto i te ipurau tapatoru 250mL, tāpirihia te 50mL wai, 10mL (pH=10) o te chloramine buffer, he iti o te 1% violetine, ka wiri pai.Whakawetohia ki te otinga paerewa 0.01mol/L EDTA tae noa ki te huri i te otinga mai i te kowhai ki te papura hei pito mutunga, ka tuhi i te rōrahi kai V.
2. Tātaitanga: Nickel(g/L)=5.869 × V × C
V: te rōrahi o te otinga paerewa EDTA i pau i roto i te miramira (mL)
C: kukū molar o te otinga paerewa EDTA (mol/L)
1. Te Whakaritenga o te otinga F- paerewa
① Wairewa paerewa me te kukū-F o te 5g/L: Kia tika te pauna i te 11.0526g NaF (Analytical Reagent, maroke i roto i te oumu i te 120°C mo te 2h, rongoa i roto i te desiccator me te pounamu pauna hei whakamahi, tika ki te 0.0001g ina paunatia) ki te memeha I roto i te iti o te wai maturu, whakawhiti ki te 1000mL ipu rōrahi, waimeha ki te tohu, me te wiri pai.
② Wairewa paerewa me te kukū-F o te 0.1g/L: Pipette 10mL o te otinga paerewa me te kukū-F o 5g/L i roto i te ipu rōrahi o runga ake nei ki roto ki te ipu rōrahi 500mL, waimeha ki te tohu, ka rongoa i roto i te pounamu polyethylene.
③ Whakaritehia nga otinga paerewa me nga kukū-F o te 0.2-1 g/L pera i te korero i runga ake nei.
2. Te Whakaritenga o te Tapeke Ionic Strength Adjusting Buffer Solution (TISAB)
Tangohia te 500mL o te wai maturu ka hoatu ki roto i te 1L ipurau karaihe ma, ka tapirihia te 57mL o te waikawa acettic glacial, katahi ka tapirihia te 58.5g o te konutai pūhaumāota me te 12g o te konutai citrate hei whakatika me te memeha katoa, katahi ka whakamahi i te konutai hauwai parakore hei tātari. whakatika ki te pH=5.0～5.5, waimeha ki te 1L ki te wai matutu.
3. F- Te tuhi pihinga paerewa
① Pipeto 2mL o te wairewa paerewa me te kukū o te 0.1g/L ki roto i te ipurau kirihou 100mL, katahi ka tapirihia te wairewa parepare TISAB 20mL, ka maka ki roto i te aukume, te whakakorikori i runga i te whakakorikori aukume, te whakauru i te hiko hiko me te hiko tohutoro, I muri i te whakakorikori hiko mo 3min, tu mo te 30s, ka panui i te pumanawa taurite Ex;
②Whakamahia taua tikanga ki te ine i te uara pea Ex o te otinga paerewa ko te kukū F ko te 0.2～1g/L, ka tohua te kukū mai i te iti ki te teitei.Ki te pepa kauwhata, tuhia te ānau paerewa EF me te kaha E hei taurangi me te kukū F hei abscissa.
4. Te tukanga whakatau
Me pai te paipa i te 20mL o te wai totohu ki roto i te ipurau 100mL, tāpirihia te 20mL o te katoa o te katote pūreirei kaha (TISAB), oho ki runga i te whakakorikori autō mo te 3 meneti, me te ine tika i te rereketanga o te mv ki te hihiko fluorine.Kimihia te ihirangi pūkōwhai m i roto i te rerekētanga pūmanawa pūkōkōkore hoahoa hikohiko paerewa.
