Utoto wamafuta utha kugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana,Utomoni wamafuta monga utoto, mphira, ndi zina zambiri. Chifukwa chiyani utomoni wamafuta ndi wodziwika kwambiri?
Ubwino wa utomoni wa petroleum: Utoto wamafuta ndi mankhwala omwe angopangidwa kumene m'zaka zaposachedwa. Chifukwa cha mtengo wake wotsika, kusakaniza bwino, malo osungunuka otsika, Petroleum Resin madzi kukana, kukana Mowa ndi mankhwala, Petroleum Resin itha kugwiritsidwa ntchito kwambiri mu mphira, zomatira, zokutira, Petroleum Resin Mafakitale osiyanasiyana monga kupanga mapepala ndi inki.
Kusiyanitsa pakati pa utomoni wa petroleum ndi mankhwala ena opangira thermosetting ndikuti samatulutsa mamolekyulu otsika panthawi yakuchiritsa, Petroleum Resin ndipo imakhala ndi kuchuluka kwa condensation mumadzimadzi. Nthawi yochiritsa imadutsa pakuwonjezera kwachindunji. Kwa dongosolo losasinthidwa, kutsika kumakhala kochepa. Nthawi zambiri, Petroleum Resin ndi pafupifupi 2%, zomwe zikutanthauza kuti kusakhazikika pakati pa mamolekyu ndikochepa kwambiri. Mafuta a petroleum resin adaponyedwa mu nkhungu yokhazikika, Petroleum Resin kuchuluka kwa nkhungu yokhazikika komanso kuchuluka kwa zitsanzo pambuyo powumbidwa, Petroleum Resin ndi kuchepa kwa voliyumu kwa chitsanzocho kuwerengedwa.
Njira yoyesera: Sungunulani nkhungu ndikutulutsa utomoni mutawumba, Petroleum Resin ndiyeno gwiritsani ntchito ma calipers kuti muyeze bwino kukula kwa mtsempha (kuphatikiza kutalika, m'lifupi, ndi kutalika) kwa chimango cha nkhungu, Petroleum Resin yolondola mpaka 0.01 mm. . ) Ponyani chitsanzo cha utomoni pa sikelo ndi waya wamkuwa kapena ulusi watsitsi ndikuchiyeza mumlengalenga, Petroleum Resin ndiye ikani chitsanzocho m'madzi osungunuka 20, muyeze m'madzi, ndikuyezera kulondola mpaka 0.001 g.
