Througth oxidation stability test and ageing test in bakeoven

the ageing and corrosionrestant behavior of homemade ZR881G type fireresistant oil and of that imported from abroad have been evaluated. The test results show that the ageing and corrsionresistant behavior of homemade fireresistant oil to be superior to that of fireresistant oil imported from abroad

and the price of homemade oil to be much lower than that of imported oil

hence

the homemade fireresistant oil is worth for popularizing.
