Kupatula PVC, timapanganso makadi mu polycarbonate (PC) ndi Polyethylene Terephthalate Glycol (PETG). Zipangizo zonsezi zapulasitiki zimapangitsa makadi kukhala otetezedwa kwambiri ku kutentha.

Ndiye, kodi PETG ndi chiyani ndipo n’chifukwa chiyani muyenera kuiganizira pa makadi anu apulasitiki? Chosangalatsa n’chakuti, PETG imapangidwa kuchokera ku polyester (monga momwe zilili, thermoplastic copolyester) osati PVC, ndipo imatha kubwezeretsedwanso KOMANSO kuwonongeka 100 peresenti. Komabe, imagwirabe ntchito mofanana ndi PVC, kotero ndi yolimba kwambiri ndipo imakana kukhudzidwa. Kusindikiza ndi PETG n’kosavuta ndipo mapangidwe ake amawoneka bwino kwambiri! Onani momwe mapangidwe ake amaonekera pa PETG.

Makhadi a PC ndi PETG ndi oyenera madera otentha, mwachitsanzo United Arab Emirates kapena South America, komwe kutentha kwa chilimwe kumatha kukwera mpaka madigiri Celsius 40, kapena mpaka madigiri Celsius 65 mkati mwa magalimoto. PVC imayamba kusungunuka madigiri 60.

Makhadi athu a PC ndi PETG satentha kwambiri mpaka madigiri Celsius 120. Izi zikutanthauza kuti, nthawi zina nyengo imakhala yovuta kwambiri, khadi lovomerezeka la ID limatha kusiyidwa mgalimoto panthawi yopuma nkhomaliro popanda kuda nkhawa, ndipo makina a khadi m'malo oimika magalimoto ku Toronto safunika kuchotsedwa mpaka madzulo. Makhadi awa ndi olimba kwambiri, kotero angagwiritsidwe ntchito kwa zaka khumi.

Tidzayesetsa kuti tipitirize kukwaniritsa zosowa za makasitomala athu mwa kupitiriza kupanga, kupanga ndi kupereka zinthu zatsopano komanso zapamwamba.
