Polyvinylpyrrolidone Crosslinking

Khoom piav qhia:

Cov yeeb yaj kiab ntawm polyvinylpyrrolidone crosslinking muaj cov pob tshab me ntsis thiab cov dej vapor permeability txaus. Tom qab tus ntoo khaub lig-txuas polyethylene yog rhuab, inflated (stretched), txias thiab zoo li tus, thaum nws yog reheated rau saum toj no lub crystallization kub, nws muaj peev xwm rov qab mus rau nws cov qub duab thiab loj (uas yog, nws muaj zoo nco). Kev sib txuas ntawm polyethylene feem ntau siv hauv kev lag luam suav nrog hluav taws xob sib txuas polyethylene, peroxide cross-linked polyethylene thiab silane cross-linked polyethylene. Radiation cross-linked polyethylene zaj duab xis muaj zog.
