Thoob cov hniav zoo thiab thoob cov hniav yuav thaum peb yuav thoob cov hniav thiab lwm yam khoom siv tshuab, feem ntau nyuaj siab ib yam, uas yog yuav ua li cas thiab yuav qhov ntawd, yuav hom twg.Cia lub tshuab zawj hydraulic tuav thoob cov hniav piav qhia yuav ua li cas yuav thoob cov hniav rau koj!
Cov cua qhov tau pom nyob ib ncig ntawm qhov chaw kub ntawm lub thoob cov hniav ua haujlwm, thiab cov cua qhov chaw kuj pom nyob rau ntawm phab ntsa ze ntawm cov kab noj hniav.Lub stomata hauv kneading casting yuav muab faib ua nyias stomata, invasive stomata thiab reverberating stomata, thiab nyob rau hauv cov txheej txheem ntawm kev tsim shrinkage kab noj hniav thiab porosity ntawm cov combustion, feem ntau ntawm gaspaning. alloy yog siab dhau lawm, los yog ntau dhau roj yog invaded nyob rau hauv cov kua hlau filling txheej txheem, cov muaj pes tsawg leeg ntawm lub saum toj no shrinkage kab noj hniav los yog stoma yuav aggravated.Los ntawm kev tsom xam ntawm cov thoob cov hniav, peb yuav pom tau hais tias stomatal faib yog random, thiab lub qhov yog loj, feem ntau spherical thiab pob spherical, muaj peev xwm txiav txim siab hais tias qhov no stomatal yeej belongs rau stomatal invas.
