QXME 103P; Asphalt Emulsifier, Hydrogenated Tallow Amine, Stearyl Amine

Tsananguro pfupi:

Chigadziko chekubatanidza, chikamu chinobuda: chinobatanidza chakasimba chine viscosity yakanyanya iyo inobatsira pakugadzikana kweCRS emulsions.

Kuvandudza kugara kwenguva refu kwemugwagwa: Sechinhu chinosunga musanganiswa weasphalt, asphalt yakasanganiswa inogona kubatanidza matombo pamwe chete kuti igadzire chimiro chakasimba chemugwagwa, zvichivandudza zvikuru kugara kwenguva refu uye kuramba kumanikidzwa kwemugwagwa.

Asphalt ine emulsified inoshandiswa zvakanyanya mukuvaka migwagwa, kugadzirisa uye kuvaka patsva. Inogona kushandiswa sechinobatanidza musanganiswa weasphalt kuti ibudirire kusimbisa kugara kwenguva refu uye kugadzikana kwemugwagwa, ukuwo ichideredza mari yekuvaka uye kusvibiswa kwezvakatipoteredza. Pamusoro pezvo, asphalt ine emulsified inogonawo kushandiswa sechifukidziro chisingapindi mvura, chinhu chinovhara denga uye chinhu chinovhara madziro emukati memugero, uye ine mashandiro akanaka ekudzivirira mvura.

Kushandiswa Kwechigadzirwa

Kugadzira asphalt yakagadzirwa ne emulsifiers yepamusoro-soro kunoita kuti kuvaka kuve nyore. Hapana chikonzero chekudziisa asphalt kusvika pakupisa kwakanyanya kwe170 ~ 180°C usati washandisa. Zvinhu zvemineral zvakaita sejecha nejecha hazvidi kuomeswa nekupiswa, izvo zvinogona kuchengetedza mafuta akawanda nesimba rekupisa. . Nekuti asphalt emulsion inoshanda zvakanaka, inogona kugoverwa zvakaenzana pamusoro pe aggregate uye ine kunamira kwakanaka nayo, saka inogona kuchengetedza huwandu hweasphalt, kurerutsa maitiro ekuvaka, kunatsiridza mamiriro ekuvaka, uye kuderedza kusvibiswa kwenharaunda yakapoteredza. Nekuda kwezvibatsiro izvi, asphalt yakagadzirwa ne emulsified haingokodzeri chete pamigwagwa yekugadzira, asiwo kudzivirira maslope embankments, kudzivirira mvura pamatenga ezvivakwa nemapako, kudzivirira ngura pamusoro pezvinhu zvesimbi, kuvandudza ivhu rekurima uye hutano hwezvirimwa, nzira dzese dzechitima, kugadzirisa jecha remugwenga, nezvimwewo. Inoshandiswa zvakanyanya mumapurojekiti mazhinji. Nekuti asphalt yakagadzirwa ne emulsified haingogone chete kuvandudza tekinoroji yekuvaka asphalt inopisa, asiwo kuwedzera huwandu hwekushandiswa kweasphalt, asphalt yakagadzirwa nekukurumidza.

Asphalt emulsifier rudzi rwesurfactant. Maumbirwo ayo emakemikoro ane mapoka emafuta anonyungudika uye anonyungudika. Inogona kunyungudika panzvimbo iri pakati peasphalt particles nemvura, nokudaro ichideredza zvakanyanya simba remahara renzvimbo iri pakati peasphalt nemvura, zvichiita kuti ive surfactant inoumba emulsion yakafanana uye yakagadzikana.

Surfactant chinhu chinogona kuderedza zvakanyanya kushushikana kwemvura kana chikawedzerwa zvishoma, uye chinogona kushandura zvakanyanya hunhu hwe interface nemamiriro e system, nokudaro zvichigadzira kunyorova, emulsification, furo, kushambidzwa, uye kupararira. , antistatic, lubrication, solubilization uye nhevedzano yemabasa ekuita zvinodiwa pakushandisa.

Hazvina mhosva kuti rudzii rwesurfactant, molecule yayo inogara iine chikamu chehydrocarbon chein chisiri chepolar, hydrophobic uye lipophilic uye boka repolar, oleophobic uye hydrophilic. Zvikamu zviviri izvi zvinowanzowanikwa pamusoro. Migumo miviri ye active agent molecule inoumba chimiro chisina kuenzana. Nokudaro, chimiro chemorekuru chesurfactant chinoratidzwa nemorekuru ine amphiphilic iyo inopophilic uye hydrophilic, uye ine basa rekubatanidza zvikamu zvemafuta nemvura.

Kana ma surfactants adarika huwandu hwakati hwemvura (critical micelle concentration), anogona kugadzira micelles kuburikidza ne hydrophobic effect. Chiyero chakanakisa che emulsifier che emulsified asphalt chakakura zvikuru kupfuura huwandu hwe critical micelle.
