Kev sib piv thiab kev tsom xam ntawm roasted lub teeb liab thiab lub teeb liab ntuj
Infrared qhov muag teev raws li cov ntaub ntawv iav plhaub tau muab faib ua cov ntaub ntawv nyuaj thiab cov ntaub ntawv mos, qhov nthuav dav coefficient ntawm cov ntaub ntawv mos iav plhaub yog siab, qhov nthuav dav coefficient ntawm cov ntaub ntawv nyuaj iav plhaub yog tsawg. Feem ntau hais lus, qhov qis dua qhov nthuav coefficient ntawm lub iav plhaub, qhov kev nyab xeeb ntawm lub teeb yog. Tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias ib puag ncig, lub iav plhaub tsis yooj yim rau tawg thaum nws ntsib dej. Yog li ntawd, lub teeb uas ua los ntawm cov iav tawv tawv muaj qhov kev nyab xeeb siab dua li qhov uas ua los ntawm cov iav mos mos.
Feem ntau, qhov nthuav dav coefficient ntawm lub iav plhaub ntawm lub qhov muag muag yog nyob nruab nrab ntawm 85 thiab 90, thaum lub teeb ntawm tus qauv nyuaj yog nyob nruab nrab ntawm 39 thiab 41. Txawm li cas los xij, qhov nthuav coefficient ntawm R125 semi-roasted liab iav plhaub yog nyob nruab nrab ntawm 46 thiab 48, thiab cov nyhuv tawg yog qhov tsis zoo piv rau cov qauv tawv iav plhaub, uas yog tshwm sim los ntawm kev txwv ntawm cov txheej txheem ci liab. Yog hais tias qhov expansion coefficient tsawg dhau los yog qhov nthuav coefficient loj dhau, cov xim ntawm lub teeb liab yuav tsis ua tiav, Raws li qhov no, peb lub tuam txhab txais cov qauv tshiab thiab cov txheej txheem tsim khoom tshiab los tsim lub plhaub iav tshiab, qhov nthuav dav. coefficient yog hais txog 40, thiab cov xim thiab lub teeb rendering nyhuv ntawm lub iav plhaub yog zoo dua li cov tsoos ib nrab ci liab noob.
Tsim thiab txheej txheem piav qhia.
- Cov tsoos roasted lub teeb liab teeb yog coated nrog tshuaj, txheej uas muaj nyiaj nitrate, tooj liab sulfate thiab kaolin nyob rau sab saum toj ntawm lub iav plhaub, tom qab kub kub ci, annealing xim tsim, thiab ces tom qab phau ntawv ntxuav kom tshem tawm cov residual hmoov txheej ntawm lub sab saum toj ntawm lub iav plhaub.
- Npaj cov ntaub ntawv iav liab: raws li qhov sib piv ntawm cov iav plhaub raw cov ntaub ntawv xws li quartz xuab zeb thiab ntxiv ntau hom hlau ntsiab lus, nplawm kom sib tov, thiab tom qab ntawd yaj mus rau hauv cov kua iav trough rauv, thiab tom qab ntawd xa cov trough lub qhov ncauj tawm mus. lub khob plhaub pwm tshuab ua kom zoo, tsim lub plhaub iav tiav, thiab muab tso rau hauv qhov tob ntawm 30 meters ntev ntawm qhov cub annealing. Cov xim thib ob tshwm rau ntawm lub plhaub iav thaum lub sijhawm tsim khoom, thiab thaum kawg tau txais lub plhaub iav liab ntawm lub qhov.
Cov hauv qab no yog ib qho kev sib piv ntawm qhov zoo thiab qhov tsis zoo ntawm ib nrab-roasted lub teeb liab thiab lub teeb liab liab.
- Kev sib piv ntawm cov txheej txheem: vim muaj qee yam kev phom sij ntawm qee cov khoom siv tshuaj lom neeg hauv cov khoom siv hluav taws xob rov qab, nws muaj cov kev xav tau siab rau kev tiv thaiv kev nyab xeeb ntawm cov neeg ua haujlwm, lub sijhawm no, kev ntxuav cov dej khib nyiab nyob rau theem tom ntej ntawm kev thim rov qab iav plhaub muaj qee yam kev puas tsuaj ib puag ncig. Yog li ntawd, cov khoom tsis zoo ntawm cov tsoos backing liab iav plhaub tau dhau los ua ntau thiab pom tseeb. Lub ntuj liab iav plhaub belongs rau ib-lub sij hawm molding, kiag li zam qhov kev pheej hmoo los ntawm ib puag ncig muaj kuab paug, kev ua lag luam kev cia siab yog optimistic.
- Cov tsos mob sib piv:
Lub plhaub iav liab no yog xim liab ntau dua, ci liab iav plhaub yog xim daj me ntsis, qhov no yog vim qhov tseeb ntawm cov tshuaj tiv thaiv xim tsis zoo ib yam, txheej txheej uniformity thiab txheej thickness yuav cuam tshuam cov xim nyhuv hauv txheej txheej rau roasted liab. iav qhov muag teev.
- Teeb xim sib piv.
Lub teeb ci liab lub teeb lub plhaub yog xim daj me ntsis, ua rau lub teeb daj yuav tsis raug lim tawm los ntawm lub iav plhaub, yog li lub teeb pom kev daj me ntsis, thiab lub teeb liab lub teeb lub teeb lub iav plhaub liab yog ntau ntshiab, liab thiab infrared tuaj yeem nkag mus. , lub teeb daj thiab lwm yam teeb pom kev zoo yog lim tawm, yog li qhov muag liab qab pom lub teeb xim yuav liab ntau dua.
- Spectrum daim duab khuv xim.
Muab piv cov spectrum daim duab ntawm lub teeb ci liab thiab lub teeb liab liab, lub zog infrared ob lub ncov nyob rau hauv infrared wavelength ntau yam (infrared wavelength ntawm 0.76 thiab 1000um), nyob rau hauv lub wavelength 3.1-3.6 micron thiab 2.6-3.1 micron, lub ntuj liab Lub teeb qhov muag yog qhov siab tshaj qhov ci liab lub teeb hluav taws xob hluav taws xob ncov. Feem ntau hais lus, qhov ntev ntawm infrared wavelength, qhov pom tseeb infrared thermal nyhuv.
