Daim ntawv lo luam tawm

PP yog ib thaj chaw zoo phooj ywg cov ntaub ntawv uas tau tsim sai heev nyob rau hauv xyoo tas los. PP luam tawm tsis zoo, thaum ntxov siv rau cov khoom siv xws li cov ntaub nplaum, daim ntaub nplaum, daim duab yeeb yaj kiab, thiab lwm yam. . Tom qab kho qhov chaw, cov ntaub ntawv luam ntawm PP daim ntawv hluav taws xob tau zoo heev, thiab nws tau siv cov tshuaj pleev xim rau txhua hnub, tsuaj zawv plaub hau, cov ntawv nyeem khov nab kuab, cov ntawv sau hluav taws xob thiab lwm yam. Cov ultra-permeable week hauv PP hluavtaws ntawv tau dhau los ua cov khoom zoo nkauj rau feem ntau cov khoom kom zoo nkauj thiab zawv plaub hau. Daim ntawv sau "eco-clear label" yog hu ua "UNLOOK LABEL" (tseem hu ua daim ntawv pov thawj pom) hauv Tebchaws Europe.

Automotive kev lag luam

qhov nce ntawm kev sib ncawg (tsawg dua ntawm kub)); Thib ob, qhov qhia txog cov qauv ntawm cov qauv ntawm cov molecular siab siab thiab tuaj yeem pom tus nqi loj zuj zus.

Kev ntsuas kub ntawm PP yog qhov zoo dua thaj tsam li 200-300 ° C. Nws muaj kev thermal stability zoo (kev kub siab yog qhov txos yog 310 ° C), tab sis thaum kub siab (270-300 ° C), nws tuaj yeem degrade nyob rau hauv qhov ntev ntev . Txij li cov viscosity ntawm PP txo qis dua li lub tsho tus nqi nce, ua rau lub siab txhaj tshuaj thiab qhov kev txhaj tshuaj yuav ua rau lub cev tau zoo thiab ua kom lub cev deev thiab kev nyuab siab. Cov pwm kub yuav tsum raug tswj li ntawm 30-50 ° C. PP yaj tau diverge los ntawm ib qho pwm sib txawv nqaim. Thaum lub txheej txheem melting, PP absorbs tus loj npaum li cua sov ntawm fusion (ntau hom kub), thiab cov khoom kub kub tom qab moulded. Cov khoom siv PP tsis tas yuav qhuav qhuav thaum lub sij hawm ua, thiab PP shrinkage tus nqi thiab crystallinity yog qis dua PE.
