Lub hauv paus ntawm kev ua kom zoo dua cov txheej txheem sintering tom qab magnesium oxide refilling nyob rau hauv kev tswj qhov kub thiab txias, ua kom muaj huab cua ntshiab, txhim kho kev sib sau ua ke, thiab ua tiav cov txheej txheem traceability. Cov hauv qab no yog cov kev daws teeb meem tshwj xeeb:
1. Txhim kho qhov ntsuas kub tswj lub tswv yim
Txais segmented PID kub tswj: Teem ntau lub cua sov nkhaus (piv txwv li, chav sov → 500℃→ 800℃→ 1000 degree), nrog rau txhua qhov cua sov tsawg dua los yog sib npaug li 5℃/ min kom tsis txhob thermal shock;
Tiag -Lub sijhawm saib xyuas thiab kho tsis siv neeg: Siv qhov ntsuas kub tsis tu ncua nrog ob lub thermocouples. Lub kaw lus cia li txheeb xyuas qhov sib txawv thiab kho kom ntseeg tau tias qhov kub thiab txias hloov pauv tsawg dua lossis sib npaug rau ± 10 degree;
Dynamically kho lub sij hawm tuav: Zoo - kho lub sij hawm tuav raws li cov yam ntxwv batch ntawm magnesium oxide hmoov (xws li, particle loj, tej thaj chaw saum npoo) kom paub meej txaus recrystallization nyob rau hauv 1-2 teev.
Nws raug nquahu kom muab lub cub tawg nrog lub tshuab hluav taws xob ntse sintering nrog qhov kub tsis siv neeg- lub sijhawm kaw thiab lub tswb ua haujlwm txhawm rau txhim kho cov txheej txheem sib xws.
2. Txhim kho huab cua thiab ib puag ncig tswj
Siab -purity nitrogen tiv thaiv (Ntau dua lossis sib npaug rau 99.99%): Cov ntsiab lus oxygen<100ppm, positive pressure protection throughout to prevent oxidation and carbonization;
Kev tswj cov roj ntsha ntse: siab txaus siab (10L / min) los hloov huab cua hauv thawj theem, tom qab ntawd txo qis rau 5L / min kom muaj kev ruaj ntseg thaum lub sij hawm txuag hluav taws xob;
Kev ua haujlwm huv huv: Kev ua haujlwm tsawg dua lossis sib npaug li 100,000 chav huv chav ib puag ncig nrog cov av noo tas li ntawm RH Tsawg dua lossis sib npaug li 30% txhawm rau tiv thaiv cov plua plav thiab noo noo.
Cov huab cua tsis huv yog qhov ua rau tsis ua haujlwm ntawm qhov ntsuas av noo thiab yuav tsum tau saib xyuas nruj.
3. Optimized Filling thiab Compaction txheej txheem
Automated Precision Powder Ntxiv: Siv cov lus taw qhia hnyav cov hmoov adder kom ntseeg tau tias qhov ntim puv yog tswj ntawm 2.8–3.2 g / cm³;
Siab -Vibration zaus + Hydraulic Compaction: Vibration zaus 50–60Hz, kav ntev li 5–10 feeb, tshem tawm cov micropores;
Online X-ray Inspection: Ua X-ray scanning ua ntej sintering kom paub meej tias qhov tsis muaj tawm -core, voids, los yog delamination delamination.
Practice shows that when the filling density deviation is >0.2 g / cm³, qhov kev pheej hmoo ntawm kev puas tsuaj nce ntau dua 40%.
4. Txheem Txias Txias thiab Tshaj Tawm - Cov Txheej Txheem Ua Haujlwm
Kev ua kom txias hauv qhov cub: yuam cua txias lossis dej txias yog txwv nruj; Qhov ntsuas cua txias yuav tsum tswj tsawg dua lossis sib npaug li 3℃/ min;
Tawm Kub<200℃: Prevent high-temperature exposure from causing aging of the sealing adhesive or stress release in the metal;
Multi- Txheej Kev Tiv Thaiv Sealing: Txais yuav cov nplaum nplaum nplaum nplaum + hlau sealing nplhaib qauv kom ua tiav qib IP65 lossis siab dua kev tiv thaiv. Cov txheej txheem cua txias tso nyiaj rau 60% ntawm tag nrho cov kev ntxhov siab thermal thiab yuav tsum tau tswj xyuas thoob plaws.
