Kuti uchengetedze pamitengo yekutumira, vashandisi vanosarudza kutenderera polycarbonate machira zvekufambisa. Dzimwe nguva, mapepa anoputika. Zvikonzero zveizvi ndezvi:

1. National standard polycarbonate sheets break, nepo asiri-standard polycarbonate mapepa haaite. Izvi zvinodaro nekuti mapepa epasi rose epolycarbonate ane huremu hwegiremu hwepamusoro uye akaoma kupfuura asiri-standard sheets, zvichikonzera kuwanda kukuru mushure mekupetwa. Uyezve, PC polycarbonate inogara inonzwa kune notches, saka mipendero yemapepa epolycarbonate akatenderedzwa anogona "kuvhuvhuta" kana akakweshwa nematombo anopinza.

2. Mipumburu yakachengetwa kwenguva yakareba. Iyo dhayamita yemapepa epolycarbonate akakungurutswa idiki, inopfuura kure inotenderwa siyana (kazhinji, kubhenda radius ye.maviri-layer polycarbonate mapepainofanira kuva ≥ 175 times the gobvu). Nguva kubva pakurodha kuenda kunzvimbo yekuenda haifanirwe kudarika maawa matatu. Pakusvika, mapepa anofanira kusunungurwa pakarepo uye kuchengetwa muimba yekuchengetera zvinhu.

3. Micheto yemashizha epolycarbonate inoputika panguva yekufambisa. Mapepa epolycarbonate akakungurutswa anotakurwa murori mushure mekukungurutswa, zvichikonzera makwara pamusoro, uye kutakurwa kwacho kunogona kukonzera kutsemuka.
