Ikhandlela, iyithuluzi lokukhanyisa nsuku zonke, elenziwe ikakhulukazi nge-wax kapharafini.
Ezikhathini zasendulo, yayivame ukwenziwa ngamafutha ezilwane.Iyasha ikhiphe ukukhanya.
Amakhandlelakungenzeka ukuthi avela kumathoshi ngezikhathi zasendulo.Abantu bakudala babegcoba amafutha noma i-wax emagxolweni noma ezinhlakeni zokhuni bese bezibopha ndawonye ukuze benze amathoshi okukhanyisa.Kukhona nenganekwane yokuthi ezikhathini zasendulo zoBukhosi bukaQin, othile wayebophela i-mugwort nomhlanga enyanyeni, wabe esecwilisa emafutheni athile walayitha ukuze akhanyise, kamuva othile wasonga umhlanga ongenalutho ngendwangu wawugcwalisa ngengcina. futhi wayikhanyisa.
Ingxenye eyinhloko ye-wax ye-parafini yekhandlela (C25H52), i-wax kapharafini ilungiswa kusukela engxenyeni ye-petroleum ene-wax ngokucindezela okubandayo noma i-solvent dewaxing, ingxube ye-alkane eminingi ethuthukisiwe.Izithasiselo zihlanganisa amafutha amhlophe, i-stearic acid, i-polyethylene, i-essence, njll. I-stearic acid (C17H35COOH) isetshenziselwa ikakhulukazi ukuthuthukisa ukuthambile.
