Qhov zoo ntawm cov kav dej txhuas-yas tuaj yeem muab faib ua peb yam. Kev tu cev zoo tshaj plaws: Cov txheej sab hauv thiab txheej txheej ntawm cov yeeb nkab aluminium-yas yog ua los ntawm cov khoom siv tshwj xeeb polyethylene, uas yog huv si thiab tsis muaj tshuaj lom. Qhov tseem ceeb tshaj plaws yog qhov nruab nrab txheej ntawm aluminium-yas yeeb nkab yog txhuas, uas tuaj yeem tsis tsuas thaiv lub teeb, tab sis kuj thaiv cov pa oxygen. Raws li peb txhua tus paub, ib puag ncig ntawm cov kab mob phem yuav tsum muaj lub teeb thiab oxygen. Qhov nruab nrab txhuas txheej ntawm aluminium-yas yeeb nkab tiv thaiv kev loj hlob ntawm cov kab mob thiab cov algae, uas yog dhau mus txog ntawm tag nrho cov-yas yeeb nkab. Txhua-yas yeeb nkab tsis tsuas yog ntxiv ntau cov tshuaj antioxidants los tiv thaiv cov khoom los ntawm degrading, tab sis cov tshuaj antioxidants tau muab rho tawm mus rau hauv cov dej khaws cia hauv cov yeeb nkab, uas yooj yim ua rau dej paug, thiab vim tias tsis muaj lub teeb thaiv thiab oxygen. - thaiv cov khoom nyob rau hauv tag nrho cov-yas yeeb nkab, nws yooj yim heev rau cov kab mob loj hlob. ua rau cov pa phem thib ob ntawm cov dej tsis zoo. Zoo heev thiab tsis kub tsis kam: lub sij hawm ntev siv kub yog 95 degrees (50 xyoo, IMPa), qhov siab tshaj plaws siv kub yog 110 degrees, thiab thermal expansion coefficient ntawm txhuas-yas yeeb nkab yog me me. Nws muaj cov thermal expansion coefficient piv rau cov txhuas, thiab tsuas yog ib feem rau ntawm lub raj yas tag nrho. Thaum qhov kub hloov pauv, qhov deformation me me, thiab cov yeeb nkab aluminium-yas yog ib qho hloov tau yooj yim, cov yeeb nkab nws tus kheej tuaj yeem zom tau qee qhov deformation, thiab yuav tsis ua rau thermal expansion deformation ntawm cov kav dej. Qhov siab thiab tsis kub tsis kam ntawm tag nrho cov yeeb nkab yas yog qhov tsis zoo. Lub neej ua haujlwm ntev: Cov qauv saw molecular (-CH2-CH2-) ntawm PE yas siv nyob rau hauv cov yeeb nkab aluminium-yas sib xyaw yog qhov ruaj khov ntawm cov yas, thiab txij li cov txheej txhuas nyob hauv nruab nrab ntawm aluminium-yas yeeb nkab cais cov txheej sab hauv thiab sab nrauv, txheej txheej ntawm cov yas yog tso cai rau ntxiv kom txaus los tiv thaiv Stabilizer rau lub teeb thiab oxygen laus yam tsis muaj kev cuam tshuam rau kev nyiam huv ntawm cov txheej sab hauv hauv kev sib cuag nrog dej, yog li txhim kho nws txoj kev laus. khoom.
