Hais txog kev nchuav ntws tawm (2)

Qhov tseeb lub luag hauj lwm ntawm yaj Performance index hauv plastics ntau lawm

Ua ntej, ib qho tseem ceeb ntawm kev kuaj xyuas

1. Txiav txim seb cov khoom yas yog nyob rau hauv qhov kev ntsuas pib ntawm lub ntsuas los ntawm kev ntsuam xyuas lub ntsuas dej ntawm cov khoom yas.

Piv txwv, cov kua dej ntawm cov khoom no yog muab los ntawm tus neeg muas zaub yuav tsum nyob hauv ib lub caij nyoog qis, thiab qhov tshwm sim yog nyob rau hauv lub caij nyoog no, qhia tias nws muaj raws li qhov yuav tsum tau ua. Yog hais tias lub ntsuas ntawm lub hauv siab loj heev, nws txhais tau hais tias cov khoom ua los ntawm cov ntaub ntawv no tau tsis zoo thiab yuav yooj yim rau kev ua, tab sis cracking yuav tshwm sim nyob rau theem tom ntej; yog hais tias lub melt index yog tsawg, qhov kev ua tau zoo dua, tab sis nyob rau hauv kev txhaj tshuaj molding, tus nqi yuav tsum tshaj. Qeeb, cuam tshuam kev txhaj tshuaj molding, ntawm lub sij hawm no kom nce kub los yog siab thaum txhaj tshuaj kho.

2. Hauv kev ua khoom loj, cov khoom sib txawv ntawm cov khoom siv tib yog sampled los txiav txim siab seb qhov kev ntsuas ntawm lub vas yog ruaj khov rau hauv ib thaj tsam kom txiav txim seb tus batch yog ib yam khoom tsim nyog. Rau cov npawb tib yam, cov khoom sib txawv ntawm ntau cov khoom tuaj, cov dej khov loj tuaj yeem yuav muab piv rau qhov kev ruaj ntseg ntawm cov khoom khoom tuaj.

Thib ob, thawj lub ntsiab lus ntawm kev hloov kho cov khoom siv

1. Tom qab muab cov khib nyiab pov tseg rov qab, cov yas rov tuaj dua. Thawj lub npe yog raws li cov ntsiab muag yaj. Vim yog lub plag ntawm lub plhaub, nws txiav txim siab qee cov khoom ntawm cov khoom, xws li tensile zog, elongation, thiab elastic modulus.

2. Thaum nrhiav cov ntaub ntawv, cov neeg muas zaub qaum muag feem ntau xa mus rau tus neeg muag khoom ntawm lub rooj khoom ntiag tug, los yog ncaj qha los qhia tias cov ntiv tes yuav tsum muaj ntau npaum li cas thiaj tsim nyog.
