Ntxiv rau yam ntawm cov khoom faib tawm nws tus kheej, Dotting Tshuab lub viscosity ntawm kua nplaum cuam tshuam ncaj qha rau qhov zoo ntawm cov kua nplaum. Yog tias viscosity siab, lub kua nplaum taw tes yuav dhau los ua me lossis txawm raug txhuam; yog tias viscosity me me, Dotting Tshuab cov kua nplaum taw tes yuav loj dua, uas yuav nkag rau cov khoom, Dotting Tshuab thiab kua nplaum kub yuav tsum 23 ℃ { 25 ℃; qhov cuam tshuam ntawm qhov kub thiab txias ntawm cov kua nplaum ua kua nplaum, Dotting Tshuab lub tshuab viscosity tsawg zuj zus thaum qhov kub tsis txaus, qhov ntws tawm ntawm cov kua nplaum ua rau me dua, thiab cov duab kos tshwm sim ntau dua. Cov neeg tsim khoom ntawm txoj kev kho qhov kub thiab txias ntawm cov kua nplaum tau muab tias, Dotting Tshuab hauv kev coj ua, qhov ntsuas kub siab dua yuav tsum tau siv rau kev kho, kom cov kua nplaum muaj qhov muaj zog txaus tom qab kho.
Tsis tas li, cov kua nplaum yuav tsum tsis muaj npuas. Cov npuas me me yuav ua rau ntau cov khoom lag luam tsis muaj kua nplaum; txhua txhua lub sij hawm hloov hose nyob rau hauv nruab nrab, Dotting Tshuab cua ntawm qhov txuas yuav tsum tau khiav tawm kom tiv thaiv qhov tshwm sim ntawm khoob tsoo.
