Cov ntsiab lus tseem ceeb yuav tsum tau them sai sai rau thaum siv hluav taws xob cua sov rau cov roj cua sov

Lub thermal conductivity roj rauv hluav taws xob rhaub yog cov roj tshwj xeeb uas muaj qhov zoo ntawm kev hloov hluav taws xob thiab thermal stability. Vim nws cov cua sov tsis sib xws, tsis tshua muaj zog siab, zoo hloov hluav taws xob zoo, txuag hluav taws xob, kev thauj mus los yooj yim thiab kev ua haujlwm, nws cov khoom siv thiab kev siv tau nce ntxiv hauv xyoo tas los no. Nyob rau hauv thermal stability thaum tshav kub kub hloov roj rauv, Pyrolysis cov tshuaj tiv thaiv yog ib qho yooj yim tshwm sim vim lub zos overheating ntawm cov cua sov system.
Cov hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob tsim hluav taws xob tsim hluav taws xob tsis zoo thiab qis qis qis oligomers, thiab cov tshuaj tiv thaiv polymerization ntawm oligomers tsim cov polymers uas tsis yog melting siab, uas tsis tsuas yog cuam tshuam cov roj ntws, tab sis kuj muaj tib lub thermal conduction efficiency. oxidation stabilized thaum tshav kub kub hloov roj, yaj huab cua thiab cua sov cab kuj yog tag nrho ntawm cov seem ntawm cov huab cua, tsim cov organic acids thiab colloids uas ua raws li cov roj pipeline, uas tsis tsuas yog cuam tshuam rau lub neej ntawm lub tshav kub hloov nruab nrab, thaiv lub raj, tab sis kuj yooj yim. ua rau acid corrosion ntawm lub raj xa dej, ua rau muaj kev pheej hmoo ntawm kev xau thaum lub sijhawm ua haujlwm.
Tiv thaiv kom sov hloov roj oxidation. Txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau ua kom sov - kub expansion tank. Tiv thaiv kom sov hloov roj los ntawm coking.
Thaum ua haujlwm kub ntawm cov roj hloov hluav taws xob ntau tshaj qhov ua haujlwm kub, cov yeeb nkab phab ntsa yuav coking. Raws li lub thickness ntawm coking txheej nce, siab phab ntsa kub txhawb adhesion thiab coking, thiab phab ntsa kub ntxiv tom qab thickening. Qhov tuab ntawm cov yeeb nkab phab ntsa, qhov tsis zoo ntawm cov hluav taws xob hloov hluav taws xob, thiab nws muaj feem cuam tshuam rau cov yeeb nkab tawg. Yog li ntawd, nyob rau ntawm qhov hluav taws xob ntawm cov khoom siv hluav taws xob, qhov kub thiab txias ntawm cov roj hloov hluav taws xob yuav tsum nruj me ntsis tswj kom tsis txhob siab tshaj qhov kev khiav hauj lwm kub, thiab qhov kub ntawm cov khoom siv cua sov yuav tsum tsawg dua li qhov tso cai.
Kev zam cov evaporation sai ntawm impurities xws li cov dej sib xyaw hauv cov khoom siv hluav taws xob thaum lub sij hawm cua sov, ua rau muaj kev nce siab hauv cov yeeb nkab cua sov, ua rau cov qib tsis tuaj yeem tswj tau thiab raug xwm txheej. Txhawm rau tshem tawm cov dej noo thiab lwm yam teeb thiab hnyav impurities los ntawm lub tshav kub hloov roj, nws yog ib qho tsim nyog yuav tsum maj mam ua kom sov ua ntej siv. Tsis tu ncua kuaj cov pa roj carbon monoxide, acid nqi, viscosity, flash point, melting point thiab lwm yam kev ntsuas lub cev thiab tshuaj, tsis tu ncua kuaj thiab txheeb xyuas cov ntsuas ntawm cov roj hloov hluav taws xob, raws sij hawm tuav cov kev hloov pauv zoo, thiab tshuaj xyuas cov laj thawj.
Thaum cov concentration siab tshaj 0.5mgKOH/g, viscosity hloov los ntawm 15 feem pua, lub flash point hloov los ntawm 20 feem pua, thiab cov residual carbon (mass feem) mus txog 1.5 feem pua, qhia ib tug hloov nyob rau hauv qhov kev ua tau zoo ntawm lub tshav kub. hloov roj. Ua kom zoo ntxiv cov khoom siv hluav taws xob tshiab kom ntseeg tau tias cov pa roj carbon seem hauv qhov system yog qhov ruaj khov.
Tsis tas li ntawd, tseem muaj chaw zoo rau kev txhim kho hauv daim ntawv thov ntawm thermal roj rauv hluav taws xob cua sov, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov magnesium thiab aluminium alloys. Qhov kub tsis zoo lossis tsis zoo pwm tuaj yeem ua rau tsis ruaj khov qhov ntev, ua rau deformation ntawm cov phaj saum toj kawg nkaus thaum lub sijhawm tsim khoom, ua rau muaj qhov tsis xws li kub nias, pwm nplaum, deg kev nyuaj siab, shrinkage, thiab kub npuas. Nws tseem cuam tshuam rau lub sijhawm thauj khoom, lub sijhawm txias, lub sijhawm txau, thiab lwm yam. Tsis tas li ntawd, vim undercooling thiab overheating, lub neej ntawm cov pwm yog luv luv, thiab cov hlau kim heev tuaj yeem ua rau thermal tawg, ua kom nws cov laus.
