Forced tov khoom
Lub tshuab sib tov yog ib hom kev sib tov khoom siv los sib tov thiab sib xyaw cov ntaub ntawv, xws li pob zeb, mortar, thiab lwm yam khoom siv.Cov khoom sib tov muaj cov chav sib xyaw nrog cov hniav sib hloov uas txav cov ntaub ntawv nyob rau hauv ib lub voj voog los yog kauv, tsim kom muaj kev sib tsoo thiab sib xyaw ua ke uas muab cov khoom sib xyaw ua ke.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv lub tshuab sib tov yog nws lub peev xwm los sib xyaw cov ntaub ntawv sai thiab ua tau zoo, ua rau cov khoom sib xws thiab zoo ib yam.Lub tshuab tov khoom kuj tseem tsim los tswj ntau yam khoom siv, suav nrog cov ntaub ntawv qhuav thiab ntub dej, ua rau nws tsim nyog rau kev siv ntau yam kev lag luam.
Tsis tas li ntawd, cov khoom siv yuam kev yog qhov yooj yim rau kev khiav lag luam thiab tswj, thiab tuaj yeem ua raws li cov kev xav tau tshwj xeeb, xws li lub sijhawm sib xyaw, cov khoom siv, thiab kev sib xyaw ua ke.Nws kuj muaj ntau yam thiab tuaj yeem siv rau ob qho tib si batch thiab kev sib xyaw ua ke tas li.
Txawm li cas los xij, kuj tseem muaj qee qhov tsis zoo rau kev siv lub tshuab sib tov.Piv txwv li, lub tshuab tov khoom yuav xav tau lub zog loj rau kev khiav lag luam, thiab tuaj yeem tsim ntau lub suab nrov thiab plua plav thaum lub sijhawm sib tov.Tsis tas li ntawd, qee cov ntaub ntawv yuav nyuaj rau kev sib xyaw ntau dua li lwm tus, uas tuaj yeem ua rau lub sijhawm sib xyaw ntev dua lossis muaj kev hnav thiab tsim kua muag ntawm cov hniav sib tov.Thaum kawg, tus tsim ntawm lub tov khoom yuav txwv tsis pub nws muaj peev xwm los tuav cov ntaub ntawv uas muaj viscosity siab los yog nplaum sib xws.
