Qhuav Ice Cleaning Tshuab Ntxuav Txoj Kev

Zoo ib yam li cov hlau, iav, yas thiab dej qab zib blasting, cov dej khov qhuav blasting xov xwm cov dej khov qhuav tau nrawm nrawm rau hauv cov cua kub siab thiab cuam tshuam rau saum npoo yuav tsum tau ntxuav. Lub cim tshwj xeeb ntawm kev ntxuav dej khov qhuav yog tias cov dej khov qhuav vaporize thaum lub sijhawm cuam tshuam. Lub zog ntawm cov dej khov qhuav qhuav ploj thaum lub sijhawm cuam tshuam. Kev hloov pauv sai sai tshwm sim ntawm cov dej khov qhuav qhuav thiab qhov chaw yuav tsum tau ntxuav. Qhov no ua rau cov khoom CO2 sai sublimate rau hauv cov pa roj. Cov dej khov qhuav nthuav dav ze li ntawm 800 zaug hauv ntim li ntawm ob peb txhiab ntawm ib thib ob, yog li tsim "micro tawg" ntawm qhov cuam tshuam. Txij li thaum CO2 evaporates, cov txheej txheem dej khov qhuav qhuav tsis tsim cov khoom pov tseg, tsuas yog tshem tawm cov av kom khaws thiab ntxuav.

Tsis zoo li lwm cov xov xwm blasting, cov dej khov qhuav qhuav yog txias heev (-78 degree ). Qhov ntsuas kub qis no muab cov dej khov qhuav ntxuav cov khoom siv thermodynamic tshwj xeeb uas cuam tshuam rau cov khoom siv hluav taws xob ntawm cov av adhered. Vim qhov kub sib txawv ntawm cov dej khov qhuav qhuav thiab qhov chaw yuav tsum tau ntxuav, thermal shock tshwm sim. Cov khoom kub txo qis, qhov brittleness nce, thiab cov dej khov qhuav tuaj yeem cuam tshuam thiab tawg cov av txheej.
