1.Kawirikawiri amagwiritsidwa ntchito pazida zapadera, polyethylene ndi yabwino kwambiri yaiwisi, pambuyo pa gawo linalake, likhoza kukhala loyenerera thovu kachulukidwe, mphamvu yabwino kutchinjiriza, mkulu kulemera kubala kuzizira kusungira zipangizo. kuyamwa chinyezi, koma pamtengo wokwera pang'ono
2.Zosungirako zozizira zomangira zosungirako zozizira ziyenera kukhala ndi ntchito yabwino yosungiramo kutentha, yotsika mtengo komanso yololera, yoyenera kusankha zipangizo zopangira kutentha. Old original.Do malo msonkhano, ubwino ndi kumanga yabwino, mofulumira liwiro, mafoni
3.Kusankha kosungirako kozizira n'kofunika kwambiri kwa firiji, chifukwa kusungirako kuzizira kumakhala kosiyana ndi malo ena osungiramo katundu.Sankhani mbale yoyenera yosungiramo malo ozizira. ndi zina zofunikira zachilengedwe.Chotero, posankha gulu la chipinda chozizira, chiyenera kuperekedwa kuzinthu ndi mphamvu zowonongeka za gululo.
Posankha zipangizo, chonde tcherani khutu ku kachulukidwe ka polyurethane ndi makulidwe a mbale yachitsulo.Kuchuluka kwazitsulo zazitsulo za opanga nthawi zonse kuyenera kukhala oposa 0.4 mm.Malinga ndi mfundo za dziko, kachulukidwe thobvu la ozizira yosungirako gulu kuposa 40kg/m3.Tsopano pa msika, zikuluzikulu zopangira bolodi wapadera ozizira yosungirako ntchito ozizira yosungirako ndi polyphenylene, polyethylene ndi polyphenylene mafuta.Kachulukidwe kazinthu zotchinjiriza zotenthetsera zopangidwa ndi thovu la polyphenylene ndizowonda, ndipo gawo la kutchinjiriza kwamafuta silokwera kwambiri;Pambuyo pa gawo lina la polyethylene, imatha kutulutsa thovu zosungirako zozizira zokhala ndi kachulukidwe koyenera komanso kutsekemera kwamafuta, ndipo imakhala ndi mphamvu zambiri zonyamula katundu;Polyphenylene resin imakhala ndi mayamwidwe amphamvu amadzi, koma kutentha kosakwanira.Chifukwa chake, sangweji ya polyurethane ili ndi ntchito yabwino kwambiri.Ngakhale mtengo wake ndi wokwera pang'ono, bolodi la polyurethane lili ndi ntchito yabwino kwambiri yotchinjiriza ndipo silimamwa chinyezi.
