Nkag siab txog cov ntawv thov ntawm siab -kub resistant yas pallets yuav tsum tau saib dhau ntawm qhov chaw- cov lus nug ntawm "qhov twg kev lag luam siv lawv." Hauv paus, nws yog hais txog qhov sib txuam ntawm cov khoom siv nrog cov chaw tshwj xeeb physicochemical. Txhawm rau tshawb xyuas lawv qhov chaw thov, ib tus yuav tsum ua ntej txheeb xyuas qhov cuam tshuam tshwj xeeb ntawm cov ntsiab lus txwv: "siab kub."
"High kub" tsis yog ib qho metric tab sis ib qho kev sib xyaw ua ke uas txhais los ntawm qhov kub thiab txias, lub sij hawm raug, thiab qhov kub ntawm qhov chaw. Kev sib cuag luv luv nrog lub tshav kub ua rau muaj qhov sib txawv ntawm cov khoom yuav tsum tau muab piv rau qhov ntev ntev ntawm qhov chaw nyob hauv ib puag ncig - kub; Ib yam li ntawd, cov thermal stress tshwm sim los ntawm cov cua kub qhuav txawv kiag li los ntawm qhov kub, ntub dej los yog tshuaj hnyav vapors. High-cov yas pallets uas muaj qhov kub thiab txias tau tsim tshwj xeeb los tswj cov qauv kev ncaj ncees thiab kev ua haujlwm ruaj khov nyob thoob plaws qhov chaw muaj ntau yam thermal.
Tsav los ntawm kev xav tau los tiv thaiv cov thermal sib txawv, daim ntawv thov tseem ceeb rau cov pallets no muaj nyob rau hauv cov txheej txheem ua cov khoom nruab nrab. Hauv kev tsim cov txheej txheem-xws li txheej txheej ntawm tsheb lossis kho cov khoom siv hluav taws xob- cov khoom ua haujlwm yuav tsum nkag mus rau qhov chaw qhuav lossis qhov cub thaum so ntawm lub pallets. Nyob rau hauv cov xwm txheej no, cov pallets yuav tsum tiv taus cov cua sov tas li ntawm 150℃txog 200 degree. Lawv yuav tsum tiv thaiv kev deformation uas tuaj yeem cuam tshuam qhov chaw ua haujlwm thiab yuav tsum tsis txhob tso qis -molecular- cov khoom hnyav uas tuaj yeem cuam tshuam rau qhov chaw ua haujlwm.
Hauv kev ua zaub mov noj, daim ntawv thov logic tsom rau cov teeb meem tshwm sim los ntawm qhov kub thiab txias. Cov txheej txheem xws li ntxuav, steaming, thiab pasteurization feem ntau cuam tshuam rau siab - qhov kub thiab txias los yog immersion ncaj qha rau hauv dej kub. Ntawm no, siab -kub resistant pallets yuav tsum tiv thaiv kev nkag mus ntawm cov dej molecules thiab cov txiaj ntsig plasticizing nyob rau hauv tshav kub. Lawv yuav tsum tiv thaiv kev thauj khoom-cov kabmob tsis muaj peev xwm vim cov khoom muag muag, xyuas kom lawv cov khoom muaj raws li cov zaub mov- tiv tauj cov qauv kev nyab xeeb, thiab tiv thaiv kev tawg thaum lub sijhawm kub hloov pauv sai.
