Nekuvandudzwa kwemigwagwa yemumaguta, kuvandudza uye kushandiswa kwemavara asina-kutsvedza pavement coating kwave kuwanda uye kuwanda. Iyo yeruvara pavement haina kungoita basa rekushongedza, asiwo ine basa rekunyevera. Colored non-slip pavement inzira yakakosha inoshanda. Iri rudzi rwepavhu rakaputirwa neruvara rwe-anti-slip coating pane yakarongwa kuitira kuti pavement ipfume mu-anti-slip function.
Petroleum resin inogona kushandiswa zvakanyanya mumaindasitiri akasiyana siyana,Petroleum Resin sependi,rabha, nezvimwewo. Nei petroleum resin ichifarirwa kudaro?
Pane nzira mbiri huru dzekugadzirisa. Imwe ndeyekugadziriswa kwehydrogenation, Petroleum Resin iyo inowedzera chisungo chakapetwa mu petroleum resin molecule, Petroleum Resin nokudaro ichivandudza ruvara rwayo uye anti-oxidation kugadzikana. Petroleum resins ane akakosha zvivakwa anogona kugadzirwa nekuwedzera mapoka epolar kana modifiers senge monoolefin kune zvigadzirwa.
Chikamu cheC9 chakatsemuka kazhinji chine unsaturated inonhuhwirira hydrocarbon makomisheni akadai sevinyl toluene, inde, methylstyrene, Petroleum Resin nezvimwe.
Magadzirirwo eC9 petroleum resin ndeaya anotevera: iyo mbishi inofanotemerwa kubvisa (bis) cyclopentadiene uye isoprene,Petroleum Resin kuti uwane mbishi nechikamu chinopfuura 50%,Petroleum Resin uye wobva wawedzera diluent inonhuhwirira hydrocarbon. pasi pekuchengetedzwa kwenitrogen,Petroleum Resin Wobva wawedzera catalyst AlCl3.
Mamiriro ekusimudzira eC9 petroleum resin kugadzirwa kumba nekune dzimwe nyika: kusimudzira indasitiri yepetrochemical inopa zvakapfuma uye zvakachipa zvigadzirwa zvekugadzira petroleum resin, Petroleum Resin saka kugadzirwa kwepetroleum resin mune dzimwe nyika dzepetrochemical dzakabudirira kuri kusimukira nekukurumidza.
