1. Zr cruciblesyog ua los ntawm ib qho amazing corrosion kuj tsis tshua muaj hlau, uas muaj ib tug heev melting point, ultra-siab hardness, thiab lub zog.. Nws yog tsuas yog siv nyob rau hauv smelting tsawg hlau.
2. Cov ntaub ntawv tseem ceeb ntawm zirconium crucible
Qib: Zr60702 Zr60705
Specifications: 30ml 40ml 50ml 60ml 80ml 100ml 130m
Nws kuj tuaj yeem kho raws li tus neeg siv khoom ntau yam tshwj xeeb-puab qhov chaw.
Txuj: ASTMB550
3. Zr cruciblestuav qhov kub siab txog 2200 degrees thiab muaj kev ruaj ntseg zoo heev. Lawv yog cov khoom zoo tshaj plaws high-temperature refractory khoom.
4. Cov ntawv thov
Zr crucibles tuaj yeem siv rau cov nplaim hluav taws kub ntawm sodium peroxide, feem ntau ntawm 550 degree, nyob rau lub sijhawm no, txog 2 mg ntawm zirconium nkag mus rau hauv lub cev nplaim hluav taws kub. Nws cov kab mob kis tau qis dua li cov hlau, npib tsib xee, nyiaj crucibles, thiab txawm platinum crucibles. Feem ntau, lub crucible tuaj yeem yaj 100 zaug. Zirconium crucibles ua rau tsis tshua muaj paug ntawm impurities thiab yog ib qho zoo heev crucible rau cov qauv ua.
5. Yuav ua li cas xaiv lub crucible rau melting?
Kev xaiv ntawm lub crucible yog ib feem tseem ceeb ntawm melting. Kev xaiv ntawm lub crucible yuav tsum xav txog cov yam ntxwv ntawm cov qauv, cov khoom yuav tsum tau ntsuas, thiab kev cuam tshuam ntawm cov khoom ntawm lub crucible ntawm kev ntsuas. Cov khoom siv feem ntau siv crucibles rau cov qauv melting yog raws li hauv qab no.
| Khoom siv | Ua haujlwm kub / C | Tsim nyog reagents | Lus ceeb toom |
| quartz | 1000 | Potassium Pyrosulfate | 1000-1200 degree pib deform |
| nyom | tsawg dua 300 | Ammonium Chloride, Ammonium Nitrate | 400 degree pib deform |
| porcelain | 1000-1200 | Potassium hydrogen sulfate | Yooj yim rau kev cuam tshuam nrog alkali thiab hydrofluoric acid |
| Platinum-Iridium | 900 | Hydrofluoric acid, sodium carbonate | 1000 degree pib volatilize |
| kub | 700 | sodium hydroxide | Melted ntawm 1050 degree, kuj cuam tshuam nrog aqua regia |
| nyiaj | 500 | sodium hydroxide | 960 degree yaj |
| hlau | 500-600 | sodium peroxide | 1400 degree melting |
| npib tsib xee | 500-600 | sodium peroxide | |
| zirconium | 500-600 | sodium peroxide | |
| Corundum | 1000 | sodium hydroxide | 2050 degree melting |
| boron carbide | 1000 | sodium hydroxide | |
| graphite | 900 | ntau lub hauv paus | 135 degree melting, nitric acid, sulfuric acid, thiab oxidizing agents tsis tuaj yeem siv |
| polyethylene | 100 | Ntau yam acids thiab bases | 170 degree melting, tus neeg sawv cev oxidizing yuav tsum tsis txhob siv |
| polypropylene | 130 | Ntau yam acids thiab bases | Me ntsis decomposes ntawm 200 degree, thiab pib deform ntawm 300 degree |
6. Zrcruciblessiv ceev faj thiab tu
Muaj ntau ntau hom thiab specifications ntawm zirconium crucibles, thiab lawv tsis txwv los ntawm batch loj thiab ntau yam smelting tshuaj nyob rau hauv daim ntawv thov.
Muab tso rau hauv qhov chaw qhuav tom qab siv kom tsis txhob muaj dej los nag; Nws yuav tsum tau ci maj mam mus rau 500 degree ua ntej siv.
Cov khoom siv yuav tsum tau ntxiv raws li lub peev xwm ntawm lub crucible thiab yuav tsum tsis txhob raug nruj heev kom tsis txhob muaj thermal expansion ntawm cov hlau thiab tawg ntawm crucible.
Thaum tshem cov hlau molten, rub nws tawm nrog rab diav thiab khaws cov calipers kom me me li sai tau. Yog tias siv cov calipers thiab lwm yam cuab yeej, lawv yuav tsum ua raws li cov duab ntawm lub crucible kom tsis txhob muaj kev ntxhov siab hauv zos thiab ua rau nws lub neej ua haujlwm luv.
