Fektheri e rekisoang ka ho fetesisa ea Matla a Matla a Phahameng Pampiri - Lipampiri tsa sefa sa oli tse loketseng mefuta eohle ea tlhoekiso ea oli - Great Wall

1. Litšobotsi tsa tšebeliso ea pampiri ea sefa ea oli e jeoang:
• Ho hanyetsa mocheso o phahameng. E ka kolobisoa ka oli ea likhato tse 200 ka matsatsi a fetang 15.
• E na le karoloana e phahameng ea void. Litšila tse nang le sekheo se mahareng sa li-microns tse fetang 10. Etsa hore oli e halikiloeng e be e hlakileng le e hlakileng, 'me u finyelle morero oa ho hloekisa ntho e emisitsoeng ka har'a oli.
• E na le moea o moholo oa ho phunyeletsa, o ka lumellang lisebelisoa tsa grease tse nang le viscosity e phahameng hore li fete hantle, 'me lebelo la ho hloekisa le potlakile.
• Matla a phahameng a omileng le a metsi: ha matla a ho phatloha a fihla ho 300KPa, matla a longitudinal le a transverse tensile ke 90N le 75N ka ho latellana.

2. Melemo ea tšebeliso ea pampiri ea sefa ea oli e jeoang:
• E khona ho tlosa lintho tse bakang kankere tse kang aflatoxin oling e halikiloeng.
• E ka tlosa monko ka oli e halikiloeng.
• E ka tlosa li-acid tse mafura tse sa lefelloeng, li-peroxide, li-polymers tse phahameng tsa molek'hule le litšila tse nyenyane lehlabatheng le fanyehiloeng ka har'a oli e halikiloeng.
• E ka ntlafatsa ka katleho 'mala oa oli e halikiloeng' me ea etsa hore e finyelle 'mala o hlakileng oa kristale oa oli ea salate.
•E ka thibela ho hlaha ha oxidation ea oli e halikang le karabelo ea rancidity, ea ntlafatsa boleng ba oli e halikiloeng, ea ntlafatsa boleng ba bohloeki ba lijo tse halikiloeng, le ho lelefatsa bophelo ba lijo tse halikiloeng.
• E ka sebelisa oli e halikiloeng ka botlalo tlas'a motheo oa ho latela melao ea bohloeki ba lijo, ho tlisa melemo e metle ea moruo likhoebong. Sehlahisoa sena se sebelisoa haholo mefuteng e fapaneng ea li-filters tsa oli tse halikiloeng
Lintlha tsa laboratori li bonts'a hore ts'ebeliso ea pampiri ea sefa ea oli e jeoang e na le karolo e kholo ho thibela keketseho ea boleng ba asiti ea oli e halikiloeng, 'me e bohlokoa haholo ho ntlafatsa tikoloho ea ho hadika, ho ntlafatsa boleng ba sehlahisoa le ho lelefatsa bophelo ba lihlahisoa.
