Qhov teeb meem ntawm shedding PET tiv thaiv zaj duab xis thaum siv
Jan 18, 2023
PET zaj duab xis tiv thaiv tam sim no yog cov yeeb yaj kiab tiv thaiv ntau tshaj plaws ntawm kev ua lag luam. Nws muaj ib tug kuj nyuaj kev ntxhib los mos thiab yog kuj khawb-resistant. Thiab nws yuav tsis tig daj thiab oily zoo li PVC cov ntaub ntawv tom qab siv mus ntev. Yog li ntawd, nws yog dav siv hauv kev tiv thaiv cov khoom lag luam, tsheb, thiab lwm yam, xov tooj ntawm tes thiab lwm yam.
Yog li, koj puas paub yuav ua li cas los daws qhov teeb meem los ntawm PET tiv thaiv zaj duab xis thaum siv?
Thaum lub sij hawm kev thauj mus los thiab siv, qhov adhesion ntawm PET tiv thaiv zaj duab xis thiab cov khoom yuav tsum tau tiv thaiv tsis ruaj khov thiab yuav poob. Qhov no yog vim qhov tsis txaus viscosity ntawm cov nplaum nplaum siv hauv kev tsim cov khoom siv PET tiv thaiv zaj duab xis. Lwm qhov ua tau yog tias lub siab ntawm lub tshuab compression molding siv los ntawm tus neeg siv tsis txaus thaum cov pwm txuas nrog, los yog qhov chaw ntawm qhov profile tsis huv thiab plua plav. Los yog xim, thiab lwm yam, uas cuam tshuam cov nyhuv ntawm cov nplaum nplaum. Yog tias qhov teeb meem no tshwm sim, nws yog ib qho tsim nyog yuav tsum tau hais txog qhov ua rau, sau cov tshuaj kom raug, hloov cov kua nplaum rhiab, ua kom lub siab ntawm cov yeeb yaj kiab, lossis ua tib zoo saib xyuas qhov zoo ntawm qhov profile thaum siv zaj duab xis, thiaj li ua kom lub siab ntawm cov yeeb yaj kiab. zam tej teeb meem no. Kev ruaj ntseg zoo, lub viscosity tsis yooj yim hloov tom qab siab thiab qis kub, tsis muaj npuas nyob rau hauv tsos, yooj yim rau shear thiab xuas nrig ntaus yam tsis muaj kua nplaum residue.
