ʻElua mau ala hoʻololi nui no nā mea hana bitumen emulsified: ke ʻano hui ʻana o waho a me ke ʻano hui ʻana i loko. ʻO ke ʻano hui ʻana o waho, ʻo ia ka hana mua ʻana i ka mea kanu bitumen emulsified maʻamau, a laila hoʻohui i nā mea hoʻololi polymer latex i nā mea hana bitumen emulsified Shanxi maʻamau, a hui a hoʻoulu e hoʻomākaukau. ʻO nā emulsions polymer he mau CR emulsions, SBR emulsions, a me acrylic emulsions. ʻO ke ʻano o ka hui ʻana i loko, ʻo ia ka hoʻohui ʻana i ka pulupulu, ka plastik a me nā polymers ʻē aʻe a me nā mea hoʻohui ʻē aʻe i loko o ka bitumen kala wela a me ke anu. Ma hope o ka hui ʻana a me ke kaupaona ʻana, a me ka hōʻike ʻana i ka mana pili ma waena o ka polymer a me ka bitumen kala hui anuanu, loaʻa ka bitumen hoʻololi polymer. , a ma hope ua hoʻololi ʻia ka emulsion bitumen i hoʻololi ʻia ma o ka ʻenehana emulsification. ʻO ka polymer i hoʻohana mau ʻia i ke ʻano hui ʻana i loko ʻo SBS. Inā hoʻopaʻa ʻia ka bitumen hui anuanu no hoʻokahi hola ma hope o ka hoʻoulu ʻana, e hoʻomaʻemaʻe i ka ʻili o ka barela hoʻoulu, hoʻohui i ka wai maʻemaʻe, a hoʻomaʻemaʻe i ka pahū. E papa inoa i ka wai ma hope, a e hoʻomanaʻo ʻaʻole he hōʻiliʻili o ka wai i loko o ka bākeke e pale ai i ka loli ʻana o ka lāʻau lapaʻau, no laila e ʻike ʻia ai ka ʻaha kūkā a me nā ʻano hana ʻē aʻe. I ka hoʻohana ʻana e like me nā ʻōlelo aʻoaʻo, pono ʻoe e hana i kekahi mau hana maʻalahi e pale aku i nā poho pono ʻole i ka hana.

ʻO ka loina hana o nā mea hana bitumen emulsion:
ʻOkoʻa loa ka ikaika o ka ʻili o ka emulsion bitumen a me ka wai, a ʻaʻole hiki ke hui pū kekahi me kekahi i nā mahana maʻamau a kiʻekiʻe paha. Ke hoʻokau ʻia ka lāʻau bitumen emulsion i nā mea mīkini e like me ka centrifugation wikiwiki, ʻokiʻoki, a me ka hopena, e ulu ka emulsion bitumen i nā ʻāpana me ka nui o ka 0.1 ~ 5 μm, a e hoʻopuehu ʻia i kahi ʻaʻohe surfactant ( emulsifier-stabilizer) I loko o ka wai, no ka mea, hiki ke hoʻopili ʻia ka emulsifier ma luna o ka ʻili o Shanxi emulsified anuanu-hui ʻia nā bitumen kala ma nā wahi paʻa, ua hoʻemi ʻia ke ʻano o ke anu- hiki i nā ʻāpana bitumen kala ke hana i ka ʻōnaehana hoʻopuehu paʻa i ka wai. , ka emulsion bitumen mea hoonohonoho mea he aila-i-wai emulsion. ʻO ia ʻano ʻōnaehana hoʻopuehu he ʻeleʻele kona waihoʻoluʻu, me ka bitumen waihoʻoluʻu hui pū ʻia e like me ka māhele hoʻopuehu a me ka wai ma ke ʻano hoʻomau, a he wai maikaʻi kona i ka wela lumi. Hoʻokomo ʻia nā mea hana bitumen emulsion Ma ke ʻano, hoʻohana ʻia nā mea hana emulsion bitumen e "hoʻopuehu" i ka bitumen kala me ka wai, a laila e hoʻohui i ka wai o ka bitumen kala.

ʻO ka mea kanu bitumen emulsified wela-hoʻoheheʻe i ke kumu anu-hui ʻulaʻula bitumen, a laila hoʻopuehu i nā ʻāpana bitumen kala i hui pū ʻia i loko o ka wai wai e loaʻa ai ka emulsifier ma o ka mīkini e hana i nā pepa bitumen kala i hui ʻia i ka wai. Hoʻohana ʻia ka mīkini bitumen emulsified i hoʻohana ʻia no ka hoʻokumu ʻana i ka papa ballastless track e hoʻohana ana i ka mea kanu bitumen cationic emulsion. I mea e hoʻonohonoho ai i ka elasticity, ka paʻakikī a me ka maikaʻi o ka mīkini emulsified bitumen mea mortar, hoʻohana pinepine ʻia nā polymers e hoʻololi i ka bitumen.
