Nkag Siab Luv Kab Molecular Distillation Technology
Cov qauv kev ua haujlwm nyob rau hauv cov chaw nqus tsev siab
Luv Luv Kab Molecular DistillationKev ua haujlwm ntawm cov ntsiab cai sib txawv piv piv rau cov kev sib cav sib xyaw. Nyob rau hauv cov huab cua sov huab cua, molecules tuaj yeem mus ncaj qha los ntawm cov av evaporation kom muaj kev sib tsoo. Qhov txheej txheem sib cais no, hu ua "molecular txaus," yog nyob ntawm qhov sib txawv hauv phaus molecular hnyav dua li npau npau. Qhov kev ncua deb ntawm evaporator thiab condenser feem ntau yog 20-50mm, ua rau lub sijhawm nyob luv luv ntawm lub sijhawm ntawm lub sijhawm. Thaum cuam tshuam nrog cov roj silicone nrog cov tes taw hnyav li molecular li ntawm 5,000-50,000 daltons, cov txheej txheem no kom haum ntawm thawj cov qauv polymer.
Kev tswj qhov kub thiab txias rau cua sov -} Cov ntaub ntawv rhiab
Siv tau kub qhov kub yog qhov tseem ceeb rau kev ua tiav ntawm cov molecular distillation hauv kev tsim cov siab high {}} zoo kho mob silicone roj. Qhov tshwj xeeb tsim ntawm cov ntaub so zaj duab xis ua kom zoo ib yam 0.1-0.5mm kua txheej ntawm rhuab Evapator, txhawb nqa ib thaj chaw kub uas tsis muaj cua sov ntau dhau. Qhov no ua rau kev ua haujlwm kub siab rau hauv qab no cov ntsiab lus kub npau suav, feem ntau nyob ib ncig ntawm 150-250℃rau ntau dua li 400℃hauv qab huab cua siab. Nrog cov PID Advanced Pid txhim kho, qhov kub ruaj khov nyob rau hauv ± 0.5℃yog tswj nyob thoob plaws evaporation nto.

Siab - Precision Sstr|- Cov roj siicone roj rau kev ua kom zoo ib yam thiab kom tsis txhob muaj kev sib xyaw ua ke. Kom ua tiav qhov xav tau<3 APHA color specification for gyroscope lubricants, a major aerospace manufacturer turned to Toption MDS-50CE systems. By processing 1,000 cSt dimethyl silicone oil at 220°C under 0.5 Pa vacuum, the system was able to reduce particulate matter from 50 particles/mL (≥10μm) to <5 particles/mL, surpassing industry requirements. To avoid lens fogging, optical equipment applications call for lower viscosity oils (100-350 cSt) with minimal volatile content. The use of multi-stage distillation achieved a total volatile level of <50ppm, doubling the operational life from 18 to 36 months.
