Kampani yathu yakhala ikupanga zida za phula la phula kwa zaka zambiri. Zida zotsukira phula zimakhala ndi migolo yofulumira, kuteteza zachilengedwe, kusapachikidwa kwa mbiya, kusinthasintha kwamphamvu, kutaya madzi m'thupi, kuchotsa slag zokha, chitetezo ndi kudalirika, komanso kusamuka bwino.
Komabe, asphalt ndi chinthu chotentha kwambiri. Zikagwiritsidwa ntchito molakwika, zimakhala zosavuta kubweretsa zotsatirapo zoyipa. Ndiye ndi malamulo ati omwe tiyenera kutsatira tikamagwira ntchito? Tiyeni tifunse akatswiri amisiri kuti atithandize kufotokoza:

1. Asanayambe kugwira ntchito, zofunikira zomanga, malo otetezera ozungulira, voliyumu yosungiramo phula, ndi zida zogwiritsira ntchito, zida, mapampu a asphalt, ndi zipangizo zina zogwirira ntchito zamakina oboola mipiringidzo ziyenera kufufuzidwa kuti ziwone ngati ziri zachilendo. Pokhapokha ngati palibe cholakwika ndi momwe mungagwiritsire ntchito bwino.
2. Mtsuko wa asphalt uyenera kukhala ndi pobowo lalikulu kumapeto kwina ndi potulukira mbali ina kuti mbiyayo ikhale ndi mpweya wokwanira pamene mbiya imachotsedwa ndipo phula silimatengedwa.
3. Gwiritsani ntchito burashi ya waya kapena chipangizo china kuti muchotse nthaka ndi zowononga zina zomwe zimayikidwa kunja kwa mbiya kuti muchepetse slag mu mbiya.
4. Pamakina a tubular kapena mwachindunji otenthetsera phula, kutentha kuyenera kukwezedwa pang'onopang'ono kumayambiriro kuti phula lisasefukire mumphika.
5. Pamene makina opangira phula omwe amawotcha phula ndi mafuta otengera kutentha ayamba kugwira ntchito, kutentha kuyenera kukwezedwa pang'onopang'ono kuchotsa madzi mu mafuta otumizira kutentha, ndiyeno mafuta otengera kutentha ayenera kulowetsedwa mu makina otsekemera kuti achotse migoloyo. .
6. Kwa makina otsekemera omwe amagwiritsa ntchito gasi kuti achotse mbiya, migolo yonse ya asphalt ikalowa m'chipinda chosungiramo mbiya, kusinthana kwa gasi kumayenera kutembenuzidwira kumbali ya chipinda cha barrelling. Migolo yopanda kanthu ikatulutsidwa ndikudzazidwa, chosinthira chosinthira gasi chotayika chiyenera kutembenuzidwira mbali yomwe ikupita ku chimney.
7. Pamene kutentha kwa asphalt m'chipinda cha asphalt kufika pamwamba pa 85 ° C, pampu ya asphalt iyenera kutsegulidwa kuti iwonongeke mkati kuti ifulumizitse kutentha kwa phula.
8. Kwa makina opangira phula omwe amawotcha mwachindunji kutentha kwa kuyesera, ndi bwino kuti musatulutse phula lomwe lachotsedwa pagulu la migolo ya asphalt, koma kuti likhale ngati phula kuti liziyenda mkati. M'tsogolomu, phula linalake liyenera kusungidwa nthawi iliyonse pamene asphalt imaponyedwa, kuti phula ligwiritsidwe ntchito mwamsanga panthawi yotentha. Pampu ya asphalt imagwiritsidwa ntchito pozungulira mkati kuti ifulumizitse kusungunuka ndi kutentha kwa phula.
