Utoto wamafuta umakhala ndi ntchito zosiyanasiyana, Utomoni wamafuta umakhala ndi kusakanikirana bwino ndi mphira wachilengedwe, ndipo umatha kukhala ngati chokhuthala komanso chofewa. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi ma resin ena, Petroleum Resin ndipo itha kugwiritsidwanso ntchito ngati chosinthira. Mafuta a petroleum ndi mafuta opangidwa ndi thermoplastic opangidwa ndi mafuta, onunkhira kwambiri, osasunthika a hydrocarbon resins. Ili ndi mawonekedwe amtengo wotsika wa asidi, Petroleum Resin wabwino miscibility, kukana madzi, kukana Mowa ndi kukana mankhwala. Ili ndi kukhazikika kwa mankhwala ku asidi, Petroleum Resin ndipo imakhala ndi mawonekedwe osintha kukhuthala komanso kukhazikika kwamafuta. Chitsanzo cha kagawidwe ka petroleum resin application.
Kugwiritsa ntchito utomoni wamafuta: utoto: utomoni wa petroleum umagwiritsidwa ntchito popanga utoto wosiyanasiyana ndi penti wamisewu. Amasakaniza ndi mafuta owuma kuti apange varnish. Ikhoza kupititsa patsogolo kukana kwa alkali ndi kukhudzidwa kwa varnish. Itha kugwiritsidwa ntchito popanga primer kuti ipititse patsogolo kutentha komanso kukana madzi. Kupanga utoto wapakati sikumangopulumutsa 10% yamafuta a masamba, Petroleum Resin komanso kumathandizira gloss, Petroleum Resin water resistance, Petroleum Resin acid ndi alkali resistance ya filimu ya utoto.
Mphira: Utomoni wamafuta ngati chowonjezera cha mphira ukhoza kulowa m'malo mwa utomoni wamtundu wa Gumaron, Petroleum Resin womwe utha kukulitsa kukhuthala, kupititsa patsogolo kusakanikirana ndi kutulutsa. Mafuta a petroleum okhala ndi malo ochepetsetsa ochepa amatha kugwiritsidwa ntchito ngati mapulasitiki opangira mphira, ndipo omwe ali ndi malo ochepetsetsa kwambiri angagwiritsidwe ntchito kulimbikitsa Liu. Utoto wamafuta amtundu wopepuka ndi woyenera mphira wamitundu, utomoni wakuda wa Petroleum Resin ndi woyenera mphira wakuda.
