Kusungunuka ndi malo owiritsa a phula: Chifukwa chiyani kumafewetsa kutentha kwambiri? ​​

Asphalt, osakaniza hydrocarbons, alibe malo akuthwa chifukwa chopangidwa ndi chizolowezi chake. M'malo mwake, imawonetseratu zofewa (makamaka 40-60 ° C kwa petroleum p fortels), kupitirira komwe kumasintha kuchokera kolimba kupita ku viruus madzi. Khalidweli limayambira kuchokera ku mawonekedwe ake a colloidal:

Mphamvu: Pamatentha kwambiri, madzi amadzimadzi amadzimadzi (malteran) mkati mwa phulusa la phula, ndikuchepetsa matcheki. Izi zimachepetsa mphamvu zapakatikati, zomwe zimapangitsa kufesa.
Kukhutiritsa kwa kutentha: Mavidiyo a phula a phula a phula amagwa ndikutentha. Mwachitsanzo. Asphalts osinthidwa (e.g.
Kuwira ndi kuwonongeka:
Asphalt akuwongolera musanafike powiritsa (pansipa 470 ° C), kumasula mpweya woopsa ngati benzene. Chifukwa chake, malo owira sioyenera kuposa malo owonda (~ 204 ° C), yomwe imasonyezera chiopsezo chotentha mukamatenthetsa.

Tanthauzo:

Kulephera panjira: Kutentha kwamachilimwe kupitirira 50 ° C kumatha kufewetsa asphalt, kumapangitsa kuwonongeka kwamuyaya ngati chizolowezi.
Zothetsera: Gwiritsani ntchito magombe osinthika (E.g., SBS) kapena zowonjezera zowonjezera kuti zithandizire kutentha kwamanja.
Mwachidule, phula la phula chifukwa cha kusokonezeka kwa colloidal ndi matenthedwe ophera magazi, kufunikira kwa zinthu zakuthupi kuti zikhale zolimba.
