Mpira phula
Mawonekedwe ndi kugwiritsa ntchito
Phula la phula nthawi zambiri limafewetsa pamwamba pa 115 ° C, monga dzinalo likusonyezera. Phula la phula limawoneka ngati njere yaying'ono ngati njere yokhala ndi mawonekedwe a tinthu tating'onoting'ono. Kulikonse kuli 80%, ndipo ili ndi mawonekedwe a kaboni yokhazikika, yoluene yopanda zinthu, malo ochepera, komanso phulusa phulusa. Kugwiritsidwa ntchito kwambiri ngati zowonjezera pamatope ophulika, ntchentche yophulika kwa hook, ntchentche yophulika, ndi kuponyera mipweya, komanso kusintha kwa mpweya wabwino kwambiri komanso kuteteza.
Njira Zokonzekera
Phula la phula limapangidwa potentha, kusungunula, kupopera mbewu, ndikuziritsa phula la moto. Onjezani asphalt asphalt adagwiritsa ntchito poyesa kukhazikika kwa zitsulo za sefet ndikuwotcha kuti zisungunuke. Nthawi yomweyo, kuyatsa magetsi ofunda, ndipo mafuta a phula adzaphulitsidwa kuchokera pachifuwa, ndipo atomikidwa m'magawo ang'onoang'ono ndi mpweya. Mitundu ya phula mwachilengedwe imakhazikika mwamphamvu ndi mpweya mkati mwa nsanja yozizira, kenako ndikuziziritsa kukhosi la nsanja yozizira yomwe imakwaniritsa zofunikira
Izi zili ndi mawonekedwe a kaboni yokhazikika, yopanda tanthauzo, imasungunuka, komanso phulusa phulusa. Amagwiritsidwa ntchito kwambiri pamatope a ntchentche a hook, ntchentche yophulika kazisi kokonza, kuphukira ndi kuponyera zida, komanso zida zovomerezeka. Ndizowonjezera kwa kaboni ndipo imatha kutenga nawo mbali muubwenzi ndi mpweya, kukonza mphamvu yakuthupi kuti ithe kupirira kutentha kwambiri ndi kukokoloka kwabwino
