1. Kodi matanki a asphalt amapangidwa bwanji ndi ukadaulo wake wokonza?
Matanki a asphalt amagwiritsidwa ntchito kwambiri pantchito yomanga misewu, zomwe zimabweretsa mwayi kwa ogwira ntchito, koma kodi mukudziwa momwe akasinja a phula amapangidwira? Tiyeni tione pamodzi.
1). Popanga ndi kupanga, m'pofunika kumvetsera kuchepetsa vuto la asphalt yotsalira kwambiri pansi ndi kulephera kuchotsa kwathunthu, ndikuyesera kupanga zotsalira za asphalt kuti zigwiritsidwe ntchito bwino zosakwana centimita imodzi, zomwe zingathenso kuchepetsa. mlingo wa magwiritsidwe.
2). Mapangidwe a thanki ya asphalt ayenera kukwaniritsa zofunikira zenizeni, ndikuwonetsetsa kuti zida za asphalt zomwe zimachotsedwa pang'ono zitha kuphatikizidwa kwambiri ndi ukadaulo wotenthetsera wa gululo, kuti zinthu zambiri zomalizidwa zitha kupangidwa, komanso nthawi yomweyo. nthawi, zofunika kupanga ang'onoang'ono ndi lalikulu mtanda akhoza anakumana. Mofananamo, kudzazidwa kwa asphalt kumapangidwanso mofananamo.
3). Ngati thanki ya asphalt imatha kuthetsa vuto la kuchotsa phula, ndiye kuti thanki ya asphalt imatha kupanga mwachindunji zinthu zotentha kwambiri, zomwe zimakhala zosavuta kwambiri. Opanga thanki ya phula amanena kuti ndikofunikira kuwonetsetsa kuti nthawi yayitali yogwira ntchito ya thanki ya asphalt sikudutsa ola limodzi, chifukwa chake ndikofunikira kukhazikitsa njira yoyendetsera mafuta otenthetsera kutentha kwambiri, kutsika kwamagetsi komanso kutentha kwakukulu, ndi chiopsezo chochepa.

2. Momwe mungachepetsere kupezeka kwa mavuto omwe amapezeka m'matangi a asphalt
Pambuyo pa thanki ya asphalt, ndikofunikira kuyang'ana ngati kulumikizidwa kwa magawo osiyanasiyana a kasinthidwe ndikokhazikika komanso kosakhazikika, ngati magawo ogwiritsira ntchito amatha kuwongolera, ngati payipi ndi yosalala, ngati ma waya oyendera magetsi ndi thanki ya phula, ndi ikani emulsified asphalt kamodzi. Chonde tsegulani valavu yodziyimira yokha kuti mulole phula lopangidwa ndi emulsified kuti lilowe bwino mu chipangizo chotenthetsera magetsi.
Kuwotcha kwachindunji kosungirako phula losungiramo phula mu thanki ya asphalt sikungokhala ndi liwiro lachangu kutentha, kumapulumutsa mafuta, ndipo sikuipitsa mpweya, ntchitoyo ndiyosavuta komanso yosavuta, ndipo makina otenthetsera odziwikiratu amathetsa vuto la kuphika. kapena kuyeretsa phula ndi mapaipi. Panthawi yogwira ntchito, chonde onani mosamala mzere wa madzi ndikusintha valavu yoyimitsa kuti mzere wa madzi ugwirizane ndi malo oyenera kuyambira pachiyambi mpaka kumapeto.
Kwa akasinja akuluakulu a zida za asphalt monga akasinja a phula, ndikofunikira kwambiri kuchita ntchito yabwino yoyendera tsiku ndi tsiku, zomwe zimapindulitsa kuchepetsa kuthekera kwa kulephera kwamakina kwa akasinja a phula, komanso kumapindulitsa kusunga magawo a magwiridwe antchito. za mankhwala ndikuwonjezera moyo wautumiki wa chinthucho.
Malinga ndi mawonekedwe ake ogwiritsira ntchito misewu, mndandanda wazogulitsa zamatanki a asphalt pazida zosakaniza za asphalt zimagawidwa m'magulu atatu: matrix a maluwa, mapulasitiki osinthidwa aumisiri, ndi apadera, omwe amaphatikizidwa pazofunikira zosiyanasiyana pamsika wopaka utoto wokongola. Mwachitsanzo, nthawi zambiri timafunika kuyesa ndi kuyesa matanki a asphalt kamodzi miyezi isanu ndi umodzi iliyonse. Ngati atapezeka kuti antioxidant yafupika kapena mafuta omalizidwa ndi odetsedwa, anti-oxidant iyenera kuwonjezeredwa nthawi yomweyo, parafini iyenera kuwonjezeredwa ku tanki yokulirapo, kapena kutentha kwapamwamba kwambiri kwa zida zotenthetsera mafuta otenthetsera thanki ya asphalt iyenera kukhala yabwino. osefedwa.
Kuphatikiza apo, pakugwiritsa ntchito akasinja a asphalt, ngati magetsi azima mwadzidzidzi kapena vuto la kayendedwe ka kayendedwe kake, kuwonjezera pa kuziziritsa kwa mpweya, m'pofunikanso kugwiritsa ntchito mafuta oziziritsa kutentha kwambiri kuti alowe m'malo, ndiye kuti, kuwonjezera pa kuzizira kwa mpweya. mafuta ozizira. M'malo ayenera kuchitidwa mwamsanga ndi mwadongosolo. Samalani kuti musatsegule pampu yamafuta ozizira kwambiri. Panthawi yosinthira, digiri yotsegulira pampu ya asphalt yosinthira mafuta imachokera ku yayikulu mpaka yaying'ono, ndipo nthawi yosinthira imafupikitsidwa momwe mungathere. Emulsified asphalt makina a asphalt thanki iyi ya phula imagwiritsa ntchito kutentha kwa L-band ngati sing'anga yotumizira kutentha, malasha oyera, gasi kapena ng'anjo yamafuta monga gwero la kutentha, ndipo amakakamizika kuti azizungulira ndi mpope wamafuta otengera kutentha kuti azitenthetsera phula mpaka opareshoni. kutentha. Chinthu chachikulu cha thanki iyi ya asphalt ndi kutentha kwachangu, komwe sikungangopanga phula lalikulu kwambiri, komanso kupulumutsa mphamvu ndikupeza pang'ono phula lotentha kwakanthawi. Kukonza phula otentha pa 160 ℃ nthawi zambiri sikudutsa maola 4. Kuonjezera apo, mafuta ozizira okwanira ayenera kuwonetseredwa kuti alowe m'malo kuti ateteze kutentha kwapamwamba kwa kutentha kwa mafuta a asphalt thanki kuti asamakhale m'malo opanda mafuta kapena opanda mafuta.
