PENGENDALIAN UDARA PADA PROSES PEMBUATAN ASAP CAIR UNTUK PENGGUMPAL DAN PENGAWET LATEKS BEKU

An engineering research has been done a friendly environmental rubber for the manufacture of liquid smoke coagulant. Research carried out three stages: making liquid smoke, compared liquid smoke with formic acid, and mixing liquid smoke with formic acid. Making liquid smoke with variation of the air. Speed 1,03 m3 / s and the time span of each (0,10,15,20,30,40,50,60) minutes and the pyrolysis temperature 450 ° C. Produces the best treatment to produce liquid smoke to the addition of air every 20 minutes with a value of 11.19% phenol in liquid smoke, the carbonyl of 11, 39% and 13.93% acid number. Liquid smoke compared with formic acid to agglomerate latex, has been proof that liquid smoke has the ability to agglomerate latex faster than formic acid, as well as for clumping rubber. Further more, tensile strength and ammonia levels for rubber proven to be consistent. Mixing liquid smoke with formic acid habe the same ability in agglomerate the latex. With in the right composition, 1,2 ml of liquid smoke mixed with 0,8 ml formic acid, produce the best quality rubber with a 350,37 % of a test value tensile and gave a real result from the 1st day until the 20th day that the level of ammonia decreased from 3,21 ppm to 1,97 ppm
