Cov khoom khaws cia, raws li cov khoom tseem ceeb hauv lub neej niaj hnub, cuam tshuam ncaj qha rau kev nyab xeeb, kev ua haujlwm ib puag ncig, thiab kev paub txog cov neeg siv khoom. Nrog rau kev xav tau ntawm cov neeg siv khoom ntau ntxiv rau cov khoom vaj khoom tsev, qhov xav tau rau kev sim cov khoom cia yog loj tuaj. Kev ntsuam xyuas tsis yog tsuas yog lub cev lub cev xws li thauj khoom- cov kabmob muaj peev xwm thiab kev puas tsuaj, tab sis kuj tseem muaj kev nyab xeeb ntawm cov tshuaj lom neeg, suav nrog cov ntsiab lus hlau hnyav thiab tso tawm cov khoom tsis zoo. Tsis tas li ntawd, cov qauv tsim, ib puag ncig tus phooj ywg ntawm cov ntaub ntawv, thiab kev ua neej nyob ntawm cov khoom khaws cia kuj yog qhov tseem ceeb rau kev sim. Kev tshawb fawb thiab qauv kev soj ntsuam xyuas kom ntseeg tau tias cov khoom khaws cia ua tau raws li cov qauv tsim nyog, tiv thaiv cov neeg siv khoom noj qab haus huv thiab kev nyab xeeb thaum txhim kho kev lag luam kev sib tw.
Cov khoom ntsuas tseem ceeb rau cov khoom khaws cia muaj xws li:
1. Kev ntsuam xyuas lub cev: suav nrog cov load-cov kabmob muaj peev xwm, lub zog compressive, puas ua haujlwm, cuam tshuam tsis kam, thiab siab -kub tsis kam.
2. Kev kuaj tshuaj lom neeg kev nyab xeeb: kuaj cov hlau hnyav (xws li txhuas, cadmium, thiab mercury), phthalates (plasticizers), formaldehyde tso tawm, thiab lwm yam teeb meem hauv cov ntaub ntawv.
3. Kev ntsuam xyuas kev nyab xeeb: kuaj xyuas cov npoo ntse thiab cov ces kaum, muaj peev xwm pinching txaus ntshai, thiab kev ruaj ntseg ntawm kev qhib thiab kaw mechanisms.
4. Environmental Performance Testing: Ntsuam xyuas cov khoom siv rov ua dua tshiab, biodegradability, thiab ua raws li cov qauv ntawm ib puag ncig (xws li RoHS thiab REACH).
5. Kev Ntsuam Xyuas Lub Neej: Simulate hnav thiab deformation nyob rau hauv lub sijhawm ntev - siv sijhawm los ntsuas cov khoom siv tau ntev.
6. Kev tshuaj xyuas cov ntawv cim npe thiab kos npe: xyuas kom cov khoom ntim khoom ua raws li cov kev cai cuam tshuam, suav nrog cov khoom tshwj xeeb thiab kev ceev faj txog kev siv.
