Tus yuam sij rau kev tiv thaiv sintering tsis ua hauj lwm tom qab magnesium oxide refilling yog nruj me ntsis tswj cov txheej txheem tsis, xyuas kom meej cov khoom purity thiab ib puag ncig huv huv, thiab muaj tag nrho cov txheej txheem ua los ntawm ib tug raws li cov chaw tsim tshuaj paus. Cov hauv qab no yog cov kev tiv thaiv tshwj xeeb:
1. Kev tswj nruj ntawm Sintering txheej txheem tsis
Parameter Correct Practice Risk Avoidance
Qhov kub thiab txias tswj tau meej meej ntawm 800-1000 degree, siv cov ntsuas kub ntsuas ntsuas rau lub sijhawm tiag tiag- saib xyuas. Tiv thaiv kom tsis tiav recrystallization vim qhov kub thiab txias ntau dhau los yog deformation ntawm lub plhaub plhaub vim yog kub dhau heev.
Lub sij hawm tuav yuav tsum tau khaws cia rau 1-2 teev kom paub meej tias cov qoob loo loj hlob txaus. Tsis txhob cuam tshuam cov txheej txheem loosening thiab txo cov rwb thaiv tsev vim lub sij hawm tsis txaus.
Cua sov Rate Tsawg dua lossis sib npaug li 5℃/ min, cov cua sov tsis sib xws. Txo thermal poob siab thiab tiv thaiv kev tawg ntawm cov hlau thiab magnesium oxide txheej.
Cooling Method Ntuj cua txias nrog rau qhov cub rau<200℃. Water cooling or air cooling is strictly prohibited. Prevents thermal stress cracks caused by rapid cooling, which can damage the seal.
Nws raug nquahu kom xaiv cov cuab yeej tshaj lij nrog PID qhov ntsuas kub tswj kom ntseeg tau tias qhov kub thiab txias nkhaus.
2. Ua kom cov khoom siv thiab cov khoom ua kom zoo
Siv siab -purity magnesium oxide hmoov (Ntau dua lossis sib npaug li 99.9%): ua raws li HG/T 6445-2025 tus qauv, Cl⁻ Tsawg dua lossis sib npaug li 0.05%, SO₄²⁻ Tsawg dua lossis sib npaug li 0.03%;
Qhov loj me me: 100-200 mesh; xyuas kom zoo thermal conductivity thiab rwb thaiv tsev;
Filling ceev tswj ntawm 2.8–3.2 g / cm³: ua tiav kev sib xyaw ua ke los ntawm kev siv cov hmoov pub mis thiab siab - zaus vibration rooj;
Kev lag luam - qib lossis cov hmoov rov ua dua yog txwv tsis pub: impurities tuaj yeem yooj yim tsim txoj hauv kev, ua rau tawg.
Xav txog kev thov rau cov chaw tsim khoom kom muab daim ntawv pov thawj kev tshuaj ntsuam xyuas cov khoom thiab X-Ray soj ntsuam daim ntawv qhia kom paub tseeb tias qhov tsis muaj tawm -cores thiab voids.
3. Ua kom muaj huab cua thiab Environmental Standards raws li cov qauv
Sintering Atmosphere: Yuav tsum tau ua nyob rau hauv siab -purity nitrogen los yog lub tshuab nqus tsev ib puag ncig, nrog rau cov ntsiab lus oxygen<100ppm;
Rhiav ib puag ncig: Kev ua haujlwm yuav tsum tau ua hauv chav huv nrog cov plua plav- ib puag ncig dawb (tsawg dua lossis sib npaug rau 100,000 chav kawm) thiab cov av noo tas li (RH Tsawg dua lossis sib npaug li 30%);
Txheej Txheem Sealing: Siv siab -kub ceramic sealing nplaum los yog hlau sealant kom ntseeg tau tias IP65 lossis siab dua tiv thaiv ntsuas.
Cov dej noo thiab plua plav yog qhov ua rau tsis ua haujlwm ntawm qhov ntsuas dej noo; Kev tiv thaiv kev kis kab mob yuav tsum tau siv thoob plaws hauv txoj kev.
4. Xaiv Cov Kev Pab Kho Kho Kom Zoo
Ua ntej cov chav uas tau koom nrog hauv kev tsim qauv ntawm HG / T 6445-2025 tus qauv, xws li:
Liaoning Jiashun Technology
Dashiqiao Meier Magnesium Khoom
Shanghai Shiye Zhentai Tshuaj
Cov tuam txhab lag luam no muaj peev xwm ua tiav kev sim thiab tuaj yeem muab cov ntaub ntawv kuaj xyuas lub Hoobkas thiab cov ntaub ntawv ntsuas kev ntsuas siab / ntub dej, ua kom cov ntaub ntawv kho tau zoo.
