Lub riam txiav yog siv los txiav cov khoom siv thiab xa nws mus rau ntawm lub tshuab sib tsoo thiab lub nplhaib sib tsoo rau kev sib tsoo. Lub riam txiav nyob rau ntawm qhov kawg qis ntawm lub tshuab, lub riam txiav thiab lub tshuab tig ua ke los txiav cov khoom siv rau hauv ib txheej khoom siv cushion ntawm lub nplhaib sib tsoo, txheej khoom siv raug tsoo los ntawm lub zog extrusion tsim los ntawm kev sib hloov ntawm lub tshuab kom ua hmoov. Qhov loj ntawm lub riam txiav yog ncaj qha cuam tshuam rau qhov chaw ntawm lub tshuab zeb. Yog tias lub riam txiav loj dhau, nws yuav cuam tshuam rau kev ua haujlwm ib txwm ntawm cov khoom siv sib tsoo. Yog tias nws me dhau, cov khoom siv yuav tsis raug txiav.
