Choyambirira, pepala lopanda kanthu ndi zinthu zamafilimu ndizosiyana, mawonekedwe ake amasiyananso.

1* Nthawi yokongola komanso yogwira ntchito yayitali:
Mafilimu ndi pafupifupi zaka ziwiri kusintha, ntchito, nthawi ndi ndalama.
Pepala lopanda kanthu lingagwiritsidwe ntchito kwa zaka zoposa khumi, zomwe ziri zokongola kwambiri.

2 * Kutumiza kopepuka:
Hollow pepala angapereke bwino mandala ndi pamwamba gloss, kuti mphamvu ya dzuwa pa unit dera mu wowonjezera kutentha okhetsedwa angagwiritsidwe ntchito mmene ndingathere.

3*Kupulumutsa mphamvu:
The matenthedwe conductivity (K mtengo) ndi otsika kuposa wamba wowonjezera kutentha filimu, kotero kuti kutentha kutaya kwambiri kuchepa.

4* Kukana kwamphamvu:
Polycarbonate ndi imodzi mwazinthu zabwino kwambiri zolimbana ndi thermoplastics. Tsamba lopanda kanthu limadziwika kuti "galasi losasweka" ndi "chitsulo chokweza".
Mosiyana ndi zimenezi, denga la filimu ndilosavuta kuti liwonongeke.

5* Chowotcha moto, chosawotcha:
Polycarbonate ili ndi kukana moto wabwino. Ndi mayeso oyang'anira zida zomangira moto, pepala lopangidwa ndi polycarbonate ndi wa kalasi B yoletsa moto, kutali ndi moto umadzizimitsa.
Ndipo filimu yomwe imakhetsedwa kutsogolo kwa moto ndi yosapiririka, dziko lapansi chaka chilichonse lidzayambika chifukwa cha moto wopangidwa ndi anthu kuti alimi a filimuyo awonongeke kwambiri.

6 * Kusinthasintha kwa kutentha kwa pepala lopanda kanthu.
Pepala lopanda kanthu la polycarbonate mu -100 madigiri Celsius sizichitika ozizira Chimaona Chimaona, mu 135 digiri Celsius si kufewetsa, m'malo ovuta zimango ake, katundu makina, etc. palibe kusintha kwakukulu.
