Sezvo kudiwa kweasphalt yepamusoro-soro kuri kuramba kuchikura, zvimwe zvinowedzera zviri kuita basa guru mukusimudzira mashandiro ayo.Masirini epetroleumzvimwe zvezvinhu izvi zviri kukwezva kutariswa kukuru muindasitiri. Pamberi pekuvandudzwa uku ndiTangshan Saiou Chemical Co., Ltd., kambani inotungamira mukugadzira petroleum resins yeasphalt.
Resin yepeturuchinhu chinoshandiswa zvakasiyana-siyana chinobva mukunyungudutswa kwemafuta asina kucheneswa. Inozivikanwa nekunamatira kwayo kwakanaka, kugadzikana kwekupisa, uye kuramba kukwegura, yakanakira kusimbisa mafomura easphalt. Nekuisa petroleum resin muasphalt, vagadziri vanogona kuvandudza zvakanyanya kusimba kwechinhu chacho, kugara kwenguva refu, uye kushanda kwacho kwese, izvo zvakakosha pakutsungirira kuoma kwemotokari dzakawanda uye mamiriro ekunze akasiyana.
Tangshan Saiou Chemical Co., Ltd. yave kambani inovimbwa nayo yemafuta emhando yepamusoro ekushandisa asphalt. Zvigadzirwa zvayo zvakagadzirirwa kusangana nezvinodiwa nevagadziri veasphalt, zvichiita kuti chigadzirwa chekupedzisira chisasvike chete asi chitopfuura mwero weindasitiri. Kuzvipira kwekambani kumhando yepamusoro uye hunyanzvi kwakaita kuti ive sarudzo yepamusoro yemakambani akawanda ari mumaindasitiri ekuvaka nekugadzira migwagwa.
Pamusoro pekuvandudza hunhu hweasphalt, petroleum resin inowedzerawo kushanda kwayo. Izvi zvinoreva kuti asphalt inogona kuiswa zvinobudirira, zvichideredza mari yevashandi uye zvichideredza nguva yepurojekiti. Uyezve, kushandiswa kwepetroleum resin kunogona kuderedza huwandu hweasphalt hunodiwa mumusanganiswa weasphalt, nokudaro zvichideredza kukanganisa kwekugadzirwa kweasphalt nharaunda.
Muchidimbu, mapetroleum resin eTangshan Saiou Chemical Co., Ltd., akabatanidzwa mumhando dzeasphalt, anomiririra kufambira mberi kukuru muhunyanzvi hwekuvaka migwagwa. Nekuvandudza mashandiro uye kugara kwenguva refu, mhinduro iyi itsva iri kugadzira nzira yemigwagwa yakasimba uye inoshanda. Sezvo indasitiri ichiramba ichichinja, basa rezvinhu zvemhando yepamusoro senge mapetroleum resin pasina mubvunzo richatonyanya kukosha.
