Kutentha kwapakatikati pa Asphalt
Zofunikira:
Malo ofewa: 50-70 ℃
phulusa: ≤ 0.5%.
Zojambulajambula ndi kugwiritsa ntchito: Mtundu uwu wa phula umakhala ndi mfundo yofananira ndipo nthawi zambiri amagwiritsidwa ntchito pophatikiza katundu wokwerera. Phulusa lanthete lalifupi ndi phula lapadera ndipo lingagwiritsidwe ntchito pa utoto wa phula, zopangidwa ndi mphira, zinthu za mphira, zonyansa, etc.
Phala lofewa ndi zotsalira za kuthira kwa phula, ndi zokolola za 54-56 za phula. Imapangidwa ndi mankhwala onunkhira omwe ali ndi mphete zopitilira zitatu, mpweya wabwino kwambiri, wokhala ndi nayitrogeni wokhala ndi herdocyccycracy courcis, ndipo pang'ono ma carbon olemera. Kulemera kwa maenje a jephals kumachokera ku 200 mpaka 2000, komwe kuli kwapamwamba kwa 3000. Kutentheka kwapakatikati kwa Asphal kumakhazikitsidwa malinga ndi mfundo zofananira. Mfundo zophweka ndi 60-80 ℃ chifukwa cha kutentha kwapakati.
