Ho tiisoa ha theipi ea sekoahelo se kentsoeng mocheso ho finyelloa ke mocheso le khatello e tsoang karolong ea ho tiisa mochine oa ho tiisa.Ha sekhomaretsi se chesang se qhibilihisang se qhibilihisoa holim'a ho tiisa holim'a tepi ea thepa, sekoahelo sa sekoahelo se hatelloa 'me se tiisitsoe ho theipi ea thepa.Theipi ea sekoahelo e kentsoeng mocheso ha e na viscosity mocheso oa kamore, empa e fetoha e khomarelang ka mor'a ho futhumatsa.
2.Sekhomaretsi sa khatello ea maikutlo (PSA)
Ho tiisoa ha theipi ea sekoahelo se nang le khatello ea maikutlo ho etsoa ke mochine o tiisang o sebelisang khatello e tsoelang pele ka mochine oa khatello, o qobella sekhomaretsi se nang le khatello holim'a sekoahelo sa sekoahelo hore se tlamahane le tepi e tsamaisang thepa.Mahlakore a mabeli a sekhomaretsi a sekoahelo sa theipi e mamellang khatello a khomarela mocheso oa kamore 'me a ka sebelisoa ntle le ho futhumatsa.
