1,Cov kauj ruam tseem ceeb rau kev xaiv
1. Txheeb xyuas cov txheej txheem cua sov
-Kua theem cua sov: Tsim nyog rau kaw tshuab nrog kub ≤ 300 ℃, yuav tsum tau them nyiaj mloog mus rau cov nyhuv ntawm viscosity ntawm fluidity.
-Gas theem cua sov: haum rau kaw tshuab ntawm 280-385 ℃, nrog high kub hloov efficiency tab sis yuav tsum tau ntau dua thermal stability.
2. Teeb qhov kub thiab txias
-Qhov kub ua haujlwm siab tshaj plaws: Nws yuav tsum yog 10-20 ℃ qis dua tus nqi nominal ntawm cov roj hloov hluav taws xob (xws li 320 ℃ nominal tus nqi, siv tiag tiag ≤ 300 ℃) kom tsis txhob coking lossis oxidation.
-Qhov kub ua haujlwm tsawg kawg nkaus: Lub viscosity yuav tsum tau ua kom ntseeg tau tias ≤ 10mm ² / s (yog tias qhov ntsuas kub yuav tsum tau nyob rau lub caij ntuj no kom tsis txhob muaj zog).
3. Kev sib koom ua ke hom
-Closed system: Kev nyab xeeb siab, haum rau kev ua haujlwm tas mus li, pom zoo cov roj hluav taws xob hloov hluav taws xob (xws li diphenyl ether sib tov).
-Qhib system: Nws yog ib qho tsim nyog yuav tau xaiv cov roj ntxhia nrog cov khoom muaj zog antioxidant (xws li L-QB300) thiab ua kom luv lub voj voog hloov.
2,Kev xaiv ntawm tshav kub hloov roj hom
Mineral hom muaj tus nqi qis thiab qhov nruab nrab thermal stability, txwv rau theem ua kua siv ≤ 300 ℃ LQB300 LQC320
Hom hluavtaws muaj zog thermal stability (txog 400 ℃) thiab yog haum rau roj theem thiab kub kub scenarios. Nws kuj tseem haum rau 240 ℃ thiab 400 ℃ biphenyl ether sib tov thiab alkyl biphenyl hom
3,Cov kev ua haujlwm tseem ceeb
1. Thermal stability: Acid tus nqi ≤ 0.5mgKOH/g thiab residual carbon ≤ 1.0% yog qhov kev nyab xeeb, thiab yuav tsum tau hloov pauv yog tias tshaj cov qauv.
2. Oxidation kev nyab xeeb: qhov qhib flash point yog ≥ 200 ℃, thiab qhov pib boiling point yog siab tshaj qhov siab tshaj plaws ua hauj lwm kub.
3. Environmental friendliness: Qhov tseem ceeb yuav tsum tau muab rau cov roj uas tsis muaj tshuaj lom thiab biodegradable hluavtaws hluavtaws (xws li diphenyl ether hom).
4,Kev xaiv ceev faj
1. Tsis txhob nkag siab yuam kev:
-Mineral roj tsis tuaj yeem siv rau hauv cov roj-theem systems, txwv tsis pub nws yog oxidation thiab to.
-Lub kaw lus kaw txwv tsis pub siv cov roj boiling tsawg thiab cov roj tsis hloov pauv.
2. Hom thiab Ntawv Pov Thawj:
-Xaiv cov khoom muaj ntawv pov thawj raws li GB23971-2009 tus qauv thiab saib cov ntawv xeem thib peb.
-Prioritize hom uas muab kev pab cuam tom qab muag, xws li Great Wall Thermal Oil thiab Tongfu Chemical.
5,Cov tswv yim kho
-Kev kuaj tsis tu ncua: Acid tus nqi thiab cov pa roj carbon seem raug kuaj txhua rau lub hlis, thiab kev hloov viscosity raug ntsuas txhua xyoo.
-System sealing: kaw cov tshuab yuav tsum muaj kev tiv thaiv nitrogen, thaum lub tshuab qhib yuav tsum tau ua kom luv luv.
