Vim li cas cov hmoov thermoplastic tsis npuas hauv lub txaj fluidized?
Vim li cas cov hmoov thermoplastic tsis ua npuas thaum ua kom npau hauv txaj fluidized?
Tej zaum yuav muaj ntau yam laj thawj rau qhov teeb meem no:
Qhov Zoo ntawm Thermoplastic Powder
Yog hais tias qhov loj me me tsis sib haum, muaj cov dej ntau dhau, impurities lossis aggregates tam sim no, nws yuav cuam tshuam rau fluidity thiab ncua ntawm cov hmoov. Yog li ntawd, nws yuav nyuaj rau cov hmoov los ua npuas lossis tswj kev ruaj ntseg hauv lub txaj fluidized.
Huab Cua Siab Thiab Airflow
Tsis txaus los yog ntau dhau ntawm huab cua siab thiab ntws cuam tshuam lub xeev ncua kev kawm ntawv thiab dispersion ntawm cov hmoov, uas ua rau tsis sib xws bubbling los yog tsis muaj nyob rau hauv lub fluidized txaj.
Fluidized-Bed Khoom
Cov qauv tsim tsis zoo ntawm cov ntaub ntawv fluidized-bed orifice phaj xws li qhov tsis zoo aperture loj lossis qis / siab porosity nrog rau qhov tsis sib xws ntawm qhov chaw lossis cov av nkos ntawm lub phaj cuam tshuam rau kev faib khoom thiab nkag mus rau huab cua hauv qhov system ua rau tsis tiav bubbling ntawm cov hmoov hauv lub txaj fluidized.
Preheating kub ntawm workpieces
Yog tias qhov kub thiab txias qis dhau los yog siab heev, nws cuam tshuam rau cov khoom adhesion thiab kho ceev ntawm cov hmoov txheej uas ua rau muaj teeb meem hauv kev tsim cov npuas uas sai sai ploj tom qab foaming tshwm sim hauv lub txaj fluidized.
