Cov neeg siv khoom hauv Sweden tau xaj 12 tons refractory hluav taws cib thiab cov pam hluav taws xob ceramic
Nyob rau lub Ib Hlis 12 tons refractory hluav taws cib thiab ceramic fiber pam yog ntim rau xa mus rau cov neeg siv khoom hauv Sweden. Zoo siab thiab zoo tus nqi refractory hluav taws cib thiab rwb thaiv tsev thermal cov ntaub ntawv hauv Topower Refractory.
Ceramic fiber ntau daim pam yog ib lub teeb-zoo refractory khoom uas yuav siv tau nyob rau hauv qhov kub thiab txias ib puag ncig los sau cov rwb thaiv tsev thiab tshav kub rwb thaiv tsev thiab ntau yam kev lag luam hauv ob sab phlu. Lub suab nqus thiab pom cov nyhuv yog qhov zoo thiab ua haujlwm siab. Txaus siab rau qhov kub thiab txias, qhov kub tsis kam ntawm 950-1400 degrees Celsius, muaj zog tensile zoo thiab toughness. Txhawm rau kom ntseeg tau tias kev siv cov nyhuv ntawm qhov chaw cia khoom, cov khoom siv muaj qee yam kev tiv thaiv corrosion, tab sis nws tsis tuaj yeem nrog cov alkali muaj zog. Muaj zog acid sib xyaw hauv qee qhov chaw cia yuav ua rau daim pam tsis zoo.
Qhov thib ob, lub tsev khaws khoom tsis tuaj yeem ntub dhau los yog raug ncaj qha rau lub teeb ntawm lub hnub. Ob leeg tsis haum rau kev khaws cia ntawm fiber ntau daim pam, uas yuav ua rau cov khoom tawg lossis pwm. Yog li ntawd, qhov chaw huab cua ntawm ob yuav tsum tau zam. Qhov tseem ceeb
Yog tias daim pam ceramic fiber tsis zoo, yuav tsum tau ua raws li kev cai ib puag ncig. Tsuas yog nyob rau hauv txoj kev no peb tuaj yeem txuag cov khoom zoo dua
Cov nram qab no ceramic fiber pam manufacturers yuav qhia rau koj yuav ua li cas hloov tej hub fiber ntau pam hloov thaum sintering?
1. Ua ntej sintering: Qhov kub ntawm qhov kub ntawm cov txheej txheem no tseem ceeb heev. Raws li qhov kub thiab txias, lub cev ntawm daim pam ceramic fiber ntau txo, tab sis qhov ceev thiab kev siv zog hloov tsis loj. Muaj kev hloov pauv. Nyob rau theem no, lub cev yog yooj yim heev rau phua. Vim tias cov dej noo thiab cov nplaum raug tshem tawm, ua tib zoo saib xyuas cov cua sov.
2. Nyob rau theem pib ntawm sintering: Thaum qhov kub hloov pauv me ntsis, qhov ntim tau txo, thiab qhov ceev yuav hloov ntau heev, thiab lwm yam. Cov pores kuj tau txo qis heev. Nyob rau theem no, lub blanking ntawm lub cev raug txo vim sintering, uas yog ib qho yooj yim los tsim cov phua thiab cov duab ntawm lub cev.
3. Late sintering: Qhov kub nce, tag nrho cov kev hloov pauv yog tob dua li cov kauj ruam dhau los. Ceramic fiber daim pam tab sis qhov ceev thiab siv zog hloov mus txog qhov siab tshaj plaws. Nws ua me me thiab tsis txuas rau ib leeg los tsim ib lub qhov cua cais, thiab qee qhov pores tseem nyob hauv cov nplej.
