Ka hopena o ka mālama ʻana i ka wela ma luna o nā mea hana bitumen i hoʻololi ʻia
I ka hoʻomākaukau ʻana i nā mea hana bitumen i hoʻololi ʻia, he mea nui ka mālama ʻana i ka mahana. Inā haʻahaʻa loa ka wela o ka bitumen, ʻoi aku ka mānoanoa o ka bitumen, emi ka wai, a paʻakikī hoʻi e emulsify; inā kiʻekiʻe loa ka wela o ka bitumen, ma kekahi ʻaoʻao, e ʻelemakule ai ka bitumen. I ka manawa like, e kiʻekiʻe loa ka mahana o ka inlet a me ka puka o ka bitumen emulsified, e hoʻopilikia i ka paʻa o ka emulsifier a me ka maikaʻi o ka bitumen emulsified. He mea nui ka bitumen o ka bitumen emulsified, ma ke ano he 50%-65% o ka maikai o ka bitumen emulsified.
I ka wa e pulupulu ai ka bitumen emulsified, ua hoopau ia ka bitumen emulsified, a mahope iho o ka mahuka ana o ka wai o loko, he bitumen ka mea i koe maoli ma ka honua. No laila, he mea nui ka hoʻomākaukau ʻana i ka bitumen. Eia kekahi, pono e hoʻomaopopo nā mea a pau i ka wā e hana ʻia ai ka mea kanu bitumen emulsified, e emi ana ka viscosity o ka bitumen i ka piʻi ʻana o ka mahana. No kēlā me kēia piʻi ʻana o ka 12°C, ʻoi aku ka pālua o kona viscosity ikaika.
I ka wā o ka hana ʻana, pono e hoʻomehana mua ʻia ka bitumen kumu kanu i ka wai ma mua o ka hoʻokō ʻana i ka emulsification. I mea e hoʻololi ai i ka hiki emulsification o ka micronizer, ka viscosity dynamic o ka cultivation base bitumen e hoʻomalu 'ia ma kahi o 200 cst. ʻO ka haʻahaʻa o ka mahana, ʻoi aku ka kiʻekiʻe o ka viscosity, no laila pono e hoʻonui ʻia ka paila bitumen. a me ke kaomi o ka micronizer, hiki ole ke emulsified; akā ma kekahi ʻaoʻao, i mea e pale aku ai i ka evaporation a me ka evaporation o ka nui o ka wai i loko o ka huahana i hoʻopau ʻia i ka wā o ka hana ʻana o ka bitumen emulsified, kahi e alakaʻi ai i ka demulsification, a he paʻakikī hoʻi e wela ka hoʻoulu ʻana i ka bitumen substrate kiʻekiʻe loa, ka Hoʻohana maʻamau ka micronizer. ʻO ka mahana o nā huahana i hoʻopau ʻia ma ka puka a me ka puka ʻana ma lalo o 85 ° C.
