Cov ppr tuaj yeem siv ua kev siv cov yeeb nkab dej kub kom txhaj 100 degrees dej npau

Nthuav txhua PPR cov kav dej tuaj yeem siv rau cov kav dej kub, tab sis nco ntsoov tias PPR cov kav dej tau muab faib ua cov kav dej txias thiab kub. Kev ntsuas kub siab tshaj plaws ntawm PPR cov kav dej yog 110 degrees, thiab lub siab tsis kam yog 1.6 lossis 2.0 MPa, tab sis PPR cov kav dej kub Nws tsis muaj kev tiv thaiv kev kub. Nthuav txhua PPR cov kav dej kub kom sov tiv taus thiab tiv taus te, thiab qhov siv rau qhov kub thiab txias yog li ntawm -20 ° C thiab 110 ° C. Kev saib xyuas dav dav yuav tsum tau them rau: 1. PPR cov kav dej kub tuaj yeem hloov mus rau lwm qhov
