Nws ua haujlwm li cas
Lub phaj cua sov sib pauv dav dav yog siv tshwj xeeb hauv cov txheej txheem thermal ntawm cov khoom nruab nrab uas muaj ntau cov khoom khov thiab cov fiber suspensions lossis cua sov thiab txias ntawm cov kua viscous. Vim tias cov channel ntawm ib sab yog tsim los ntawm cov chaw sib cuag-welded uas ntawm cov phaj corrugated dimple, Cov channel ntawm sab tod yog cov channel dav dav tsim ntawm cov phaj corrugated dimple uas tsis muaj cov ntsiab lus sib cuag. Qhov no ua kom cov kua dej ntws du hauv cov channel dav dav. Tsis muaj "cheeb tsam tuag" thiab tsis muaj kev tso cov khoom khov lossis cov suspensions.

Xiav channel: rau cov kua qab zib
Cov channel liab: rau dej kub
Cov txiaj ntsig tseem ceeb ntawm kev siv tshuab
