Asphalt asphals ndi emulsion yopangidwa ndi asphal omwazika m'madzi. Madzi mmenemo ndi ochepa chabe mu phula. Pambuyo pa phula litathiridwa kapena kusakaniza, imaphwanya emulsion ndi madzi mu phula la phula limatuluka. Chiwerengero cha madzi ku phula la phula limangokhudza kukwera mtengo kwa phula ndi zoyendera phula, komanso zimakhudzanso kuchuluka kwa stalphal, komanso kumathandizanso pakusungidwa, mamasukidwe ena a phula. Chifukwa chake, ndikofunikira kuyesa phulusa kukhala pagawo la emulimenti.
Kuti adziwe phula m'malo a phula la utali, phula la phula liyenera kusokonekera. Komabe, maiko ndi mabungwe osiyanasiyana ali ndi njira zosiyanasiyana za phula lamisala. Mwachidule, pali njira zinayi zazikulu: distillation, uvuni wachulukitsa, kuwomba mwachindunji ndi kuyanika kwachilengedwe.

1. Njira yolowera
Njira zoimilirana kwambiri ndi njira ya nyenyezi ya Asm ku United States, njira yotsika kutentha ya astem, ndi njira zazikuluzikulu za kutentha kwa nyenyezi, komanso njira zotentha ndi kutentha kosiyanasiyana ndi kuchuluka kwa distillation ku United States.
(1) Njira ya Asule Discillation. United States ASMM D244-00 ikulepheretsa njira zitatu zoyambira okhazikika: Zotsalira ndi Kutalika kwamafuta ndi distillation, yotsalira mwa kusinthana, ndikukhazikika kwa 135 cukuum. Njira ya Ayipi ya Akazimu ndi kutsanulira 200g ya phula losasinthika kukhala chidebe chapadera cha aluminiyamu ndikuuyika pa 260 ° C Gawoli C Gawo la 15 kuti lipatule madzi ndi phula la utali. Zotsalira zomwe zapezedwa ndi njirayi zitha kugwiritsidwanso ntchito kuyesa katundu wa phula lotsalira.
. Pofuna kuti asphalts ena amisala, makamaka osinthika asphalts, amasambitsidwa ndi kutentha kwambiri, yomwe imakhala yotsalira kwambiri, yomwe imakhala yotsalira pa nthawi yomwe phula lopezeka idzakhudzidwa kwambiri ndipo sangawonetse mkhalidwe weniweni wa phula nthawi yolumikizidwa mukamagwiritsidwa ntchito. Chifukwa chake, njira yochepetsetsa yocheperako idawonjezeredwa ku Gawo Lachiwiri la ASTM D244. Njirayi imagwiritsa ntchito chida chotsikira komanso kuwonongeka kwa 135 ° C kwa mphindi 60.
. Maiko ambiri ku United States amagwiritsa ntchito distillation kuti athe kukhala okhazikika, koma njira zingapo sizofanana :.
2. Njira yoyera ya uvuni
Oimira kwambiri ndi njira ya Ayipi ya Ayipi komanso njira ya California, USA.
Njira ya Ayinsotion Evate ndikutenga magawo anayi okhala ndi 1000ml, kutsanulira mu uvuni ndi kutentha kwa 1h ndikuwalimbikitsa kuti ayesetse mutu wanthawi zonse.
Njira ku California, USA ndikuyenera 40g ± 0.1g ya phula la umiliri, pitilizani pa 118 № Zotsalira zimapangidwa kukhala ziyeso zoyenera kuyeza Index.
3.. Njira yolumikizira
Onse Japan ndi dziko langa limagwiritsa ntchito njirayi. Kuyesedwa kwa malo osungirako za exiced mu dziko langa ndikutenthetsa 300g ya emulsion pamtunda wamagetsi kwa 20-30min pa 163 Njira yoyeserayi imapangidwa ndi miyezo yaku Japan.
Kuphatikiza apo, kuti apeze kuchuluka kwa phula mpaka phula lopoledwa, satha kupezeka osati pongofuna kudziwa phulusa lomwe lili mu phula la umiliri, komanso pofufuza madzi mu phula la emirated. ASMM D244-00 nawonso ali ndi njira yoyeserera yamadzi asphalt.
Zotsalira zomwe zimapezeka ndi njira zosiyanasiyana zopezera phula lotsalira ndi losiyana.
Kafukufuku woyeserera wapeza kuti njira yowuma mu uvuni kwa nthawi nthawi zambiri zimabweretsa madzi osakwanira; Zotsatira za Astmi Distrillation ndizokhazikika, koma chifukwa cha zida zoyeserera zovuta, pakadali pano zimakhala zovuta kupitiliza kudziko langa. Ngakhale dziko langa limatentha mwachindunji mpaka 163 ° C kuti mupeze zotsalira ndi zinthu zomwe zimatsalira ndi zinthu zaumunthu, njira ndizosavuta, zotsatirapo zake ndizodalirika, ndipo ndizotheka.
