-30 ° C mpaka 50 ° C: Momwe Isungunula Chingwe Chimalongosola nyengo Yonse
Kumasulidwa nthawi:2025-08-07
Asphalt (chigamba chozizira) chimakula bwino pomwe miyambo yamiyambo imalephera - chifukwa cha ukadaulo wapamwamba womwe umalepheretsa kuti agonjetse kutentha ndi kuzizira kwambiri. Pano pali sayansi kumbuyo kwake:
1. Polymer Mphamvu
Asphals ozizira amaphatikizira mabulo osinthidwa ndi zowonjezera zomwe zimakhala zosinthika kudutsa kutentha kwambiri (-30 ° C mpaka 50 ° C). Mosiyana ndi asphalt asphalt (hma), omwe amakhala nyengo yozizira ndikufewetsa kutentha, mabingu awa amasinthana ndi kupsinjika kwa mafuta. Amapewa ku bratlowness nthawi ya ma freeze-thaw ndipo amaletsa kugunda pansi pa dzuwa.
2. Madzi oyendayenda
HMA pamafunika zowuma, zotentha zokhala ndi mgwirizano. Phula la ozizira, komabe, limatsatira pompopompo, loyera, kapena loundana - chisanu, chipale chofewa, kapena madzi oyimirira. Njira yake ya hydrophobic yake imalapa chinyontho, kuonetsetsa kuti kukonzanso kumasefukira m'madzi osefukira kapena misewu yofewa.
3. Kulimbikitsidwa chifukwa cha kulimba mtima
Asphal ozizira amaphatikizidwa ndi zinthu ngati ulusi wa basalt ndi ma grade okwera. Kapangidwe kameneka kumawonjezera kukana kolimba pansi pamavuto owombera, kumapangitsa Hma pamayeso okwanira. Magetsi ozama amadzaza zigawo (chilichonse ≤5cm), ophatikizidwa kuti achuluke kwambiri komanso kukhala ndi moyo wautali.
4.. Zero Kutentha, kutuluka
Palibe kuwotcha sikutanthauza kumwa mafuta pakugwiritsa ntchito, kumenyetsa kwa con. Njira zambiri zimagwiritsanso ntchito zida zobwezerezedwanso (E.g.
5. Maulendo othamanga, okhazikika
Zigamba zozizira zikafika, zigamba zozizira zimatha nthawi yomweyo, ngakhale mu -25 ° C Blozzards kapena 50 ° C. Izi "zokhala ndi" zimachepetsa kutsika mtengo ndi kukonza ndalama.
Chifukwa Chake Zili
Wozizira wa asphals asphals amayambira kuchokera ku chemistry yamafuta: Kwa misewu yolimbana ndi nyengo, si chigamba chabe-chimakhala cholimba.
