Zamadzimadzi Ndi Olimba Oziziritsa Kusindikiza Chowonjezera Kwa Anodizing Chithunzi Chowonetsedwa

Zamadzimadzi Ndi Zolimba Zozizira Zosindikizira Zowonjezera Zowonjezera Anodizing

Chiyambi cha malonda
Cold Kusindikiza Chowonjezera ndi ufa wobiriwira wobiriwira, wopangidwa ndi mchere wa nickle, mchere wa cobalt, accelerator, stabilizing agent, agent olowera, ash inhibitor, dispersing agent, pamwamba-yogwira ntchito ndi zina zotero.Amagwiritsidwa ntchito kusindikiza filimu ya aluminiumprofiles oxidation ndi filimu yamtundu wa electrolytic.

Zogulitsa Zamalonda

1. Kukana kwabwino kwa zonyansa komanso kusungidwa bwino kwa asidi ndi zamchere.

2. Njirayi ili ndi ubwino wosavuta kugwiritsa ntchito, magawo osiyanasiyana a ndondomeko, osafunikira kusintha pH kawirikawiri.

3. Pewani kusindikiza kosindikiza kuti zisachitike.

4. Pambuyo pa chithandizo chosindikizidwa, chikhoza kupititsa patsogolo kuuma kwa pamwamba ndi gloss ya mbiri ya aluminiyumu.

Kusamba Kwamba

Cold Kusindikiza Zowonjezera	Deionized madzi
5-5.5g/L	Kusamala

Process Parameters

N^i2＋	F^-	pH	Kutentha	Nthawi	Kugwiritsa ntchito
0.9 ~ 1.3g/L	0.4 ~ 0.6g/L	5.5-6.5	22-28 ℃	1μm/1.3m	0.9 ~ 1.5kg / T

Kukonza Mayankho

1. Dziwani kuchuluka kwa Ni,F ndi pH, kuwapanga kukhala mkati mwa magawo a ndondomekoyi
2. Sinthani pH mwa kuwonjezera dilute acetic acid (dilute hydrofluoric acid) kapena kuchepetsa sodium hydroxide (dilute ammonia), sungani pH mtengo pakati pa 5.5 ndi 6.5.
3. Pofuna kuchepetsa kuipitsidwa kwa madzi osamba ochapira, sungani madzi abwino ndi pH ya bafa yochapira mosamalitsa, pH siposa 4.5.

Kupaka

Cold Kusindikiza Zowonjezera zimasindikizidwa ndi polybag, 5kg net iliyonse ndi ma polybags 4 m'katoni, 20kg net iliyonse.Kutetezedwa ku kuwala pa malo ouma.

Njira Yoyesera

Kutsimikiza kwa nickel ion (Ni2+) zomwe zili
1. Njira zoyesera.
Jambulani molondola 10mL yamadzimadzi akuya mu beaker ya 250mL ya katatu, onjezerani 50mL madzi, 10mL (pH=10) ya chloramine buffer, 1% violetine pang'ono, ndikugwedezani bwino.Titrate ndi 0.01mol/L EDTA njira yokhazikika mpaka yankho likusintha kuchoka kuchikasu kupita ku utoto wofiirira ngati pomaliza, ndikulemba voliyumu yakumwa V.
2. Kuwerengera: Nickel(g/L)=5.869 × V × C
V: kuchuluka kwa yankho la EDTA lomwe limadyedwa mu milliliters (mL)
C: ndende ya molar ya EDTA njira yokhazikika (mol/L)

Kutsimikiza Kwazinthu za Fluoride Ion (F-).

1. Kukonzekera kwa F- standard solution
① Yankho lokhazikika lokhala ndi F-concentration ya 5g/L: Kulemera kwake 11.0526g NaF (Analytical Reagent, youma mu uvuni pa 120 ° C kwa 2h, sungani mu desiccator yokhala ndi botolo loyezera kuti mugwiritse ntchito, molondola mpaka 0.0001g poyeza) kusungunula Mumadzi ochepa osungunuka, tumizani ku botolo la volumetric 1000mL, tsitsani chizindikirocho, ndikugwedezani bwino.
② Njira yokhazikika yokhala ndi F-concentration ya 0.1g/L: Pipette 10mL ya njira yokhazikika yokhala ndi F-concentration ya 5g/L mu botolo la volumetric pamwambapa mu botolo la voliyumu ya 500mL, tsitsani chizindikirocho, ndikusunga mu botolo la polyethylene.
③ Konzani mayankho okhazikika ndi F-concents ya 0.2-1 g/L monga tafotokozera pamwambapa.

2. Kukonzekera kwa Total Ionic Strength Adjusting Buffer Solution (TISAB)
Tengani pafupifupi 500mL yamadzi osungunuka ndikuyika mu beaker yagalasi yoyera ya 1L, onjezerani 57mL wa glacial acetic acid, kenaka onjezerani 58.5g ya sodium chloride ndi 12g ya sodium citrate kuti mukonze ndi kusungunuka kwathunthu, kenako gwiritsani ntchito analytically pure sodium hydroxide sinthani ku pH=5.0 ~ 5.5, chepetsani ku 1L ndi madzi osungunuka.

3. F- Standard yokhotakhota kujambula
① Pipette 2mL ya njira yokhazikika yokhala ndi kuchuluka kwa 0.1g/L mu beaker ya pulasitiki ya 100mL, kenaka onjezerani 20mL TISAB buffer solution, ikani maginito, gwedezani pa maginito osonkhezera, ikani ma elekitirodi okosijeni ndi ma elekitirodi motsatana. 3min, imirirani 30s, ndikuwerenga zomwe zingatheke Ex;
②Gwiritsani ntchito njira yomweyi kuti muyeze mtengo womwe ungakhalepo wa Ex wa njira yokhazikika yomwe F ndi 0.2 ~ 1g/L, ndikusankha ndende kuchokera kutsika kupita kumtunda.Pa pepala la graph, jambulani EF yokhotakhota yokhazikika ndi EF yomwe ingathe kukhala yogwirizanitsa ndi F ndende ngati abscissa.

4. Njira yotsimikizira
Pipette molondola 20mL wamadzimadzi ozama mu beaker ya 100mL, onjezani 20mL ya mphamvu zonse za ayoni zotchingira mphamvu (TISAB), sonkhezerani pa maginito osonkhezera kwa mphindi zitatu, ndipo yesani mwachindunji kusiyana kwa mv ndi electrode ya fluorine.Pezani zofananira za fulorini m mu chithunzi cha fluorine chomwe chingatheke kusiyana muyeso wa elekitirodi.
