Makapu a pepalaKhalani ndi sera mu pepala kuti pepalalo lisayamwe madzi, makapu a mapepala amagawidwa m'makapu ozizira ndi makapu otentha amitundu iwiri, ngati nthawi zambiri mumagwiritsa ntchito makapu ozizira pa zakumwa zotentha, zoopsa pa thanzi zidzakhala zazikulu kwambiri. Makapu a mapepala ozizira amaoneka ngati sera wopopera kapena wothira sera, pakati pa 0 ~ 5 ℃, sera iyi ndi yotetezeka kwambiri, koma bola kutentha kwa madzi kudutsa 62 ℃, sera idzasungunuka, makapu a mapepala adzayamwa kusintha kwa madzi.
Kuchuluka kwa phula loyera losungunuka ndi kwakukulu, chifukwa lili ndi ma hydrocarbons ambiri onunkhira bwino. Ma organic compounds ndi mtundu wa zinthu zomwe zimayambitsa khansa, zomwe zimalowa m'thupi la munthu. Mawonekedwe a makapu a pepala otentha adzaphatikizana ndi filimu yowonjezera, osati kokha kukana kutentha, komanso kusakhala ndi poizoni komanso kopanda vuto.
Chifukwa chake, tikagula makapu a mapepala ogwiritsidwa ntchito nthawi imodzi, kuti tithe kusiyanitsa pakati pa makapu a mapepala ogwiritsidwa ntchito nthawi imodzi a makapu a zakumwa zoziziritsa kukhosi ndi makapu a zakumwa zotentha, ndipo makapu a mapepala ayenera kusungidwa pamalo opumira mpweya, ozizira, osasangalatsa komanso osadetsa, nthawi yosungira kuyambira tsiku lopangidwa siidutsa zaka ziwiri.
Ngati muli ndi mafunso, chonde dinani ulalo womwe uli pansipa kuti mupite patsamba lathu kuti mudziwe zambiri.https://www.botongpack.com/paper-cup/
