Yuav ua li cas siv thiab tswj lub quartz raj nyob rau hauv lub muffle furnace

1. Lub softening point ntawm lub quartz raj yog 1270 degrees, thiab nws yuav tsum tsis txhob ntau tshaj 3 teev thaum siv ntawm 1200 degrees.

2. Khaws lub cub tawg kom huv thiab huv. Yuav tsum tsis muaj cov khoom seem uas tshwm sim nrog SiO2 nyob rau hauv lub cub tawg. Thaum cov khoom siv hluav taws xob, txhawm rau ua kom lub tshuab hluav taws xob ua haujlwm ntev dua, tsis txhob muab cov ntaub ntawv ncaj qha rau ntawm lub tshuab hluav taws xob thiab siv lub nkoj zoo li crucible los tuav nws.

3. Raws li ib txwm muaj, nws tsis pom zoo rau cov neeg siv khoom kom dhau hydrogen hauv lub raj rauv taws. Tsuas yog cov ntsiab lus uas tsis yog-hydrogen nyob rau hauv qhov txwv explosive concentration, yog hais tias tus neeg siv yuav tsum tau siv lub raj rauv taws kom dhau hydrogen nrog cov concentration sab nraum lub explosive concentration, yuav tsum tau ua kev ntsuas kev nyab xeeb. Tsis txhob sawv ntawm ob qho kawg ntawm lub tshuab hluav taws xob. Yog tias koj dhau hydrogen, thov siv cov hlau tsis muaj hlau. Vim tias cov hlau tsis muaj steel muaj qhov thermal conductivity ntau dua li quartz, ob qhov kawg ntawm stainless hlau yuav tsum tau dej txias, txwv tsis pub O-ring kub siab dhau lawm thiab tsis tuaj yeem kaw.

4. Thov nco ntsoov muab cov ntsaws ntsaws rau hauv lub qhov cub thaum cua sov, txwv tsis pub qhov kub ntawm ob qho kawg ntawm lub qhov cub hluav taws xob yuav siab, thiab O-rings hauv flange yuav tsis tuaj yeem tiv taus qhov kub siab, ua rau tsis zoo cua nruj. Qhov kawg yog qhov tsim nyog rau kev tsim kom muaj qhov sib npaug ntawm qhov kub thiab txias.

5. Thaum cua sov, thov nco ntsoov muab cov alumina rauv ntsaws rau hauv lub qhov cub hluav taws xob, muab 2 rau ntawm ib sab, 4 nyob rau hauv tag nrho, qhov kev ncua deb ntawm ob sab ntawm lub cub tawg tuaj yeem yog 450mm (vim qhov ntev ntawm cov cua sov. ntu ntawm HTL1200 split tube rauv yog 400mm) Yog tias lub qhov cub hluav taws xob tsis tau muab tso rau, qhov kub ntawm ob qho kawg ntawm lub qhov cub hluav taws xob yog siab, thiab O-ring hauv flange tsis tuaj yeem tiv taus qhov kub siab dua, uas ua rau huab cua nruj tsis zoo. . Muab lub tshuab hluav taws xob ntsaws rau ntawm ob qho kawg ntawm lub tshuab hluav taws xob yuav pab tsim kom muaj qhov sib npaug. teb.

6. Qhov kub tsis kam ntawm lub raj quartz muaj feem xyuam rau nws cov purity. Qhov siab dua qhov purity, siab dua qhov kub tsis kam.
