Asphalt osinthidwa
Kuyambitsa Zoyambitsa
Asphalt asphalt ndi wolimba kwambiri kutentha kwa firiji, yomwe imakhazikika mu yokhazikika yokhala ndi zipolopolo ngati kutentha kwinakwake, kupereka gawo lagalasi pamtunda; Palibe malo ena osungunuka, imasungunuka mkati mwa mtundu wina, ndipo palibe zozama panthawi yolimba. Kupanga kwa phula kumakhala kovuta kwambiri, makamaka kumapangidwa ndi ma hydrocarbons okhala ndi mphete zitatu kapena zingapo, komanso sulufule, ndi sulufule, komanso mpweya woipa wambiri.
Asphalt asphalt ndi mtundu wa phulusa womwe umakonzedwa kwambiri kuchokera ku phula la phula kapena phula lamoto. Makhalidwe ake ndi malo ofewetsa kwambiri, okonda kwambiri okhazikika a kaboni kwambiri, toluene yopanda zambiri pa 25%, ndi quinoline infoled zomwe zili zosakwana 8%. Mukamapanga zopangidwa ndi kaboni pogwiritsa ntchito phula la malawi phula monga zopangira, zofunika zosiyanasiyana zimayikidwa pamfundo yophweka. Mwachitsanzo, ma electrodes amafuna 105-115 ℃, ma azode amafunikira 95-105 ℃, mfundo yayikulu kwambiri, mtengo wapamwamba kwambiri, zomwe zimachulukitsa mphamvu zamakina, zomwe zimachulukitsa mphamvu yamakina a kaboni. Panthawi yosakaniza ndi kuwumba, phula limatulutsa utsi wocheperako, kuchepetsa kuipitsidwa. Kutentha kwakukulu ndi kutentha kukagwada kumapangitsa kukhazikika kwamitundu yambiri, yomwe imasintha mtundu wa kaboni. Phula la bola la phula limatha kugawidwanso ndi madzi am'madzi ndi phula la phula. Phula la Lifa silikhala ndi madzi ndipo imatha kugwiritsidwa ntchito ndi opanga, koma imafunikira mayendedwe apadera a tanker. Asphalt asphalt ayenera kusungunuka kuti athetse chinyezi musanagwiritsidwe ntchito ngati chomangira kapena chogwirizanitsa kaboni.
Asphalt yasinthidwa imagwiritsidwa ntchito mu makampani a aluminium electrowall kuti apange maofesi obiriwira ophika, kupanga ndodo zapamwamba zamagetsi, ndi zojambulajambula zazikulu, ndipo imathanso kugwiritsidwa ntchito ngati zomata zamagetsi. Phukusi la kutentha kwambiri lili ndi mawonekedwe a kaboni yokhazikika, yopanda pake ku Tuluene, zinthu zazikulu, komanso phulusa phulusa. Zomera zambiri za kaboni, mawonekedwe ophika tokha, zojambulajambula, ma elekiti a graphite, ntchentche ya ntchentche, yophulika, ndi zida zoponyera, komanso zida zomangira. Monga zowonjezera pa kaboni, zimatha kutenga nawo gawo polumikizana ndi kaboni, kukonza kutentha kwambiri kwazinthu ndi kukana kwa chipongwe.
Kusinthidwa kwa malawi phula kumapangitsa kuti gawo lofunikira mu electrolysis a aluminium mu aluminium. Makamaka, udindo wake umawonekera makamaka m'mbali zotsatirazi:
- Monga chofunda: Mafuta osinthidwa phula ndi chingwe chachikulu chomwe chimagwiritsidwa ntchito popanga ma break adode a soderoly aluminiyamu. Zolemba zophika zisanachitike ndi mpweya woipa monga ma petroleum coke ndi asphalt cokes, komanso phula la malasha ndi ma cell a aluminiyal electrolys. Lifala ya malawi phula imatha kulumikizana pamodzi, ndikupanga zida zapadera ndi mphamvu zina ndi zojambulazo, potero zimawonjezera mphamvu ya ma electolytic cell ndi ma aluminiyamu.
- Pewani mapangidwe a aluminiyamu oxide: Pa nthawi ya ma electrolytic aluminiyamu, aluminium ma scoudised mosavuta oxidized mu aluminiyamu mu aluminiyamu mu aluminiyamu mu aluminiyamu kukhala ma oxide oxide, omwe amangobweretsa ma okonyewa a alumini, omwe amabweretsa zinyalala zamphamvu. Zina mwazinthu zina mwa mitundu yosinthidwa phula zimatha kulepheretsa mapangidwe a aluminiyumu ozizira, potengera kukonzekera bwino komanso zokolola za aluminiyamu.
Kulimbikitsidwa: Mafuta osinthidwa phula amatha kukulitsa mayendedwe a electrolyte, kulola kuti zinthu ziziyenda bwino, potero ndikuwongolera bwino zopanga za electroly aluminiyamu.
- Monga kusindikizidwa ndi Adsorption: Pamwamba ndi pansi pa cell ya electrolytic, kusinthidwa kwa malawi a ma elerolyte kumatha kupanga chipilala cha elerolyte kumapangitsa kuti kusindikizidwa kwa elerolyte kumapangitsa kuti pakhale cell ya electrolyte yolowera cell ya electrolytic. Nthawi yomweyo, imatha ku ADSORB ndikuchotsa mpweya woipa ndi zodetsa mu khungu la elema electrolytic, kukonza mawonekedwe a eleminiya komanso chiyero cha aluminiyamu.
- Mwachidule, mafilimu osinthika a phula amasewera maudindo angapo mu aluminiyam electrolysis mu aluminiyalys mu aluminium mbewu, kuphatikizapo kugwirizanitsa, kupewa mawonekedwe a alumuna, kuchititsa mawonekedwe a alumu, kukhazikika, ndi Adsorption. Ndizofunikira kwambiri kuti musinthe bwino zopanga zopanga za aluminiyamu electrolysis, kuchepetsa ndalama, ndikuwonetsetsa kuti aluminiyamu.
Kupanga Ukadaulo
Njira yowonjezera polima polima ya matenda asphalt imakonda kutengera ketoto yopitilira, ndipo ketulo yomwe itatha imatha kugwira ntchito pamlengalenga kapena kuwonjezera. Pa ntchito yakumwamba, phula lotentha limayenda mu ketulo yomwe yachitika kuyambira yachiwiri ya malasha tayipility ndipo imatenthedwa mu ketulo kuti iwonjezere asphalt asphalt. Phutulo yosinthidwa imayenda kulowa mkati mwa phula losinthidwa mokha ndipo limatumizidwa ku tank yanyimbo ya Asphalt ntchentche. Pambuyo pozizira kwachilengedwe mpaka 150-180 ℃, imayikidwa mu phula loumba loumba kuti apange zinthu zapachibale. Mafuta ndi gasi yotulutsidwa pamwamba pa riyakitala ya riyakitala yamafuta ndi mafuta osasunthika. Mukamagwiritsa ntchito opaleshoni, phula lotentha limadutsa thambo lamkati la phula lakutsogolo ndipo limaponyedwa mu ketulo. Kupanikizika mkatikati mwa ketulo kumasungidwa pa 0,5 ~ 1.MPA, ndi zotsalazo ndizofanana ndi njira yopitilira mitengo yamlengalenga. Poyerekeza ndi ma polymer polymerization, maubwino okakamiza polymer polymerization ndikuchepetsa mphamvu ya β, amachepetsa mtengo wa zigawo za phula. Pamene kutentha kofewa kumayenera kuwonjezeka, popu ya vacuum ikhoza kuyamba kusintha kwa nsanja ya distillaum pamwamba pa nsanja ya distillation, kupititsa patsogolo kuwononga mafuta mu phula mu phula losinthika; Pakafunika kuchepetsa kutentha kofalikira, mafuta am'madzi amatha kuthiridwa mu nsanja ya Flash. Zokolola zosinthidwa pogwiritsa ntchito sing'anga kutentha kwapakatikati ngati 90% ~ 96%, ndi zokolola za phula pogwiritsa ntchito ma ractor ndi 58%.
Cholinga
Asphalt yasinthidwa imagwiritsidwa ntchito mu makampani osinthika a aluminium kuti apange malo okhala ndi madokotala, popanga ndodo zapamwamba kwambiri, zolimba za graphite, ndipo imatha kugwiritsidwanso ntchito ngati mafuta opanga ma elekitiroti, etc.
