Raws li cov khoom siv yooj yim siv hauv kev lag luam niaj hnub, cov khoom lag luam yas ncaj qha cuam tshuam rau cov khoom ua tau zoo thiab kev nyab xeeb ntawm cov khoom lag luam xaus. Yog li no, tsim kom muaj kev tshuaj ntsuam txuj ci thiab qauv kev tshuaj xyuas yog qhov tseem ceeb los ua kom muaj txiaj ntsig zoo ntawm cov roj hmab thiab cov khoom siv yas.
Soj ntsuam cov roj hmab thiab cov khoom yas yog feem ntau muab faib ua peb ntu: Cov Khoom Siv Raw tshuaj xyuas, thiab tshuaj xyuas cov khoom tiav ntawm cov khoom tiav. Ua ntej, ntawm cov khoom siv Raw theem, xws li ntom ntom thiab tawv tawv), xws li cov khoom muaj kuab lom (xws li cov roj hmab yas), thiab cov roj hmab tau kuaj kom ua raws li cov qauv kev ua haujlwm. Cov kev kuaj xyuas kev tshuaj xyuas ntau suav nrog infrared spectroscopy, thermogravimetric tsom (TGA), thiab ntsuas Tensile.
After entering the production phase, semi-finished products require online monitoring, focusing on dimensional accuracy, cosmetic defects (such as bubbles and cracks), and processing stability. Piv txwv li, kev sib txuas ua ke cov tshuab ntsuas yog siv los tshuaj xyuas cov khoom lag luam geometry, thaum pom kev tshuaj xyuas cov tshuab siv los txheeb xyuas qhov chaw saum npoo av. Cov tsis tsim nyog (xws li kub thiab siab) yog ua kom muaj txiaj ntsig kom tsis pub muaj cov tswv yim. Yog tias muaj kev pom muaj qhov kuaj pom, cov txheej txheem kev hloov kho tau ua kom tsis txhob muaj kev tsis xws luag. Kev xeem kawg yog ib kauj ruam tseem ceeb ua ntej ua zaub mov xa tuaj, encompassing peb lub ntsiab kev lag luam, ib puag ncig tsis kam, thiab kev nyab xeeb. Cov cuab yeej kho tshuab xws li Tensile lub zog, cuam tshuam cov kev cuam tshuam zoo, thiab puas tawm tsam. Kev ntsuam xyuas ib puag ncig tiv thaiv kev ntsuam xyuas cov khoom ua tau zoo nyob rau hauv cov khoom siab thiab qhov chaw kub, UV teeb, lossis tshuaj lom neeg. Cov hau kev muaj xws li cov siab thiab tsis tshua muaj cua cycling thiab ntsev tsuag tshuaj ntsuam xyuas. Tsis tas li ntawd, roj hmab thiab cov khoom siv yas npaj rau kev sib choc (volatile organic compound thiab biocompatibiling kev ntsuas kom tau raws li kev cai tswj hwm.
Rigor ntawm cov txheej txheem ntsuas ncaj qha cuam tshuam rau kev ntseeg tau ntawm roj hmab thiab cov khoom siv yas. Cov tuam txhab yuav tsum sib xyaw ua ke cov qauv kev lag luam (xws li ISO thiab ASTM) nrog kev kuaj cov neeg siv khoom, kev tshuaj xyuas kev tshuaj xyuas kom ntseeg tau cov ntaub ntawv raug thiab muaj kev sib tw. Kev tswj hwm kev nyab xeeb zoo thoob plaws hauv tag nrho cov txheej txheem tsis yog tsuas txhim kho cov khoom sib tw tab sis kuj muab kev ruaj ntseg rau cov ntawv thov txoj kev nyab xeeb hauv qab.
