Sera ya Parafini yoyengedwa bwino Kwambiri Porcelain Wapamwamba
Sera ya parafini, yomwe imadziwikanso kuti crystalline sera, nthawi zambiri imakhala yoyera, yopanda fungo lolimba, ndi mtundu wamafuta opangira mafuta, ndi mtundu wa sera yamchere, ndi mtundu wa sera wamafuta.Ndi kristalo wa flake kapena acicular wopangidwa kuchokera ku distillate yamafuta opaka mafuta omwe amachokera ku distillation yamafuta osakanizidwa ndi kuyenga zosungunulira, zosungunulira zosungunulira kapena sera kuzizira crystallization, kusindikiza dewaxing kupanga phula phula, ndiyeno ndi thukuta kapena zosungunulira deoiling, kuyenga dongo kapena hydrorefining.
Sera ya parafini yoyengedwa bwino kwambiri, yomwe imadziwikanso kuti phulusa labwino, ndi yoyera yolimba m'mawonekedwe ake, yokhala ndi zotupa komanso zotumphukira.Zogulitsa zake zimakhala ndi malo osungunuka kwambiri, mafuta ochepa, osamangirira kutentha kwa chipinda, palibe thukuta, palibe kumverera kwamafuta, madzi, chinyezi komanso kutsekemera kwamagetsi.

Semi-Woyeretsedwa Paraffin Sera Kwa Makandulo
Sera ya parafini ndi yoyera kapena yolimba, ndipo imasungunuka kuyambira 48°C mpaka 70 ℃.Imatengedwa kuchokera ku petroleum pochotsa mafuta opaka mafuta opepuka.Ndi crystalline kusakaniza kwa ma hydrocarbon owongoka omwe ali ndi mawonekedwe otsika kukhuthala komanso kukhazikika kwamankhwala abwino, komanso kukana madzi komanso kusasunthika.
Malingana ndi kusiyanasiyana kwa kukonza ndi kuyenga, ikhoza kugawidwa m'mitundu iwiri: parafini woyengedwa bwino, ndi parafini woyengedwa bwino.
