Peb yuav tsum xyuam xim rau dab tsi thaum ua cov hnab ore-tuj?
Hauv cov txheej txheem ntawm kev ua cov hnab ore-tuj, cov khoom siv raw khoom yuav tsum tau npaj, thiab kev sib xyaw yog qhov tseem ceeb thiab tseem ceeb txuas.
Thaum sib tov cov khoom tshiab thiab qub, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov sib xws ntawm kev sib xyaw ntawm cov khoom siv raw. Tuj hnab yuav tsum sim xaiv cov ntaub ntawv uas zoo sib xws melt index rau blending. Vim hais tias cov melting Performance index ntawm cov khoom sib txawv heev, lub melting kub yuav txawv heev.
Yog li ntawd, lub plasticization tsis tuaj yeem tsis sib xws thaum lub sijhawm plasticizing extrusion txheej txheem, uas yuav cuam tshuam rau cov duab kos, tsim cov filaments ca, thiab txo qhov zoo. Raws li qhov tshwm sim, cov thawv ntim khoom muaj cov xaim hluav taws xob siab thiab cov khoom seem, thiab tej zaum yuav ua tsis tau los tsim. Thaum lub sij hawm sib tov, xyuam xim rau lub sij hawm ziab thiab kub ntawm cov khoom siv raw.
Feem ntau yog hais txog lub zog ntawm lub hnab ntim khoom. Thaum tsim, qhov ntim ntawm lub ntim, qhov hnyav ntawm cov ntsiab lus thiab tus naj npawb ntawm cov ntim ntim yuav tsum tau txiav txim siab. Rau cov hnab ntim khoom, kev thauj mus los deb thiab cov sijhawm tuav yuav tsum tau txiav txim siab. Cov cuab yeej thauj mus los thiab txoj kev thauj mus los siv kuj yuav tsum tau muab rau hauv kev txiav txim siab.
Nyob rau hauv lub thawv ntim cov qauv, cov txheej txheem kev ntsuas yuav tsum tau ua rau lub hnab ntim cov ntaub thiab cov hlua khi tau nruj me ntsis. Los ntawm qhov kev xav ntawm kev nyab xeeb, nws yog qhov tseeb tias tag nrho cov thawv ntim tau txais cov qauv hauv qab-duab.
Tsis tas li ntawd, cov neeg siv khoom yuav tsum tsis tsuas yog saib xyuas tus nqi ntawm cov thawv ntim khoom thaum yuav khoom, tab sis tsis xyuam xim rau qhov zoo, thiab yuav tsum tau ceev faj kom poob rau hauv lub ntxiab ntawm cov hnab ntim khoom qis.
