Petroleum resin imhando ye epoxy resin ine yakaderera molecular uremu. Huremu hwemamorekuru hunowanzodzikira pane 2000. Ine thermal ductility uye inogona kunyungudutsa zvinonyungudutsa, kunyanya crude oil-based organic solvents. Iine kuenderana kwakanaka nezvimwe zvinhu resin. Iyo ine yemhando yepamusoro abrasion resistance uye kuchembera kuramba. Yayo yakakosha kuita ma paramita anosanganisira kupfavisa poindi, hue, unsaturation, acid kukosha, saponification kukosha, hama density, zvichingodaro.
Iyo yekunyorovesa nzvimbo ndiyo yakakosha hunhu hwe petroleum resin, zvinoreva kuti simba rayo, brittleness, uye viscosity zvinosiyana nekushandiswa, uye inodiwa kupfava poindi yakasiyanawo. Mumamiriro ezvinhu akajairika, nzvimbo inopfava mukugadzirwa kwemaindasitiri yerabha yakasvibiswa i70 ° C kusvika 1000 ° C, uye nzvimbo yekupfava mukugadzirwa kwemaindasitiri kwemapendi nependi i100 ° C kusvika 1200 ° C.
Uye zvakare, iyo nhanho yekuchinja tonal inokonzerwa ne ultraviolet mwenje uye thermal mhedzisiro zvakare yakakosha kuita parameter. Kukosha kweasidhi kunogona kushandiswa kwete chete kuona kuchengetedza kweasidhi-base simbi catalysts asiwo kuona iyo carbonyl uye carboxyl zvikamu zve petroleum resin kuchengetedza nekuda kweiyo oxidation.
Kuumbwa kwe petroleum resin kwakaoma zvakanyanya. Nekushambadzira uye kusimudzirwa kwekushandiswa kwayo kukuru, kune marudzi akawanda uye akawanda, ayo anogona kukamurwa kuita zvikamu zvishanu:
â Mafuta emuviri wemunhu, cycloaliphatic epoxy resin, inowanzogadzirwa kubva kuC5 chidimbu, inozivikanwawo seC5 epoxy resin;
â¡ p-xylene epoxy resin, inowanzogadzirwa kubva kuC9 fraction, inozivikanwawo seC9 epoxy resin;
⢠p-xylene-aliphatic hydrocarbon copolymer epoxy resin, inozivikanwawo seC5/C9 epoxy resin;
â£Dicyclopentadiene epoxy resin, inogadzirwa kubva ku dicyclopentadiene kana makomisheni ayo, inonzi zvakare DCPD epoxy resin. Nekuti iyi epoxy resin ine unsaturated aliphatic hydrocarbon mapoka, inonziwo reflective ring Oxygen resin.
⤠Hydrocracking petroleum resin, kazhinji C5 kana C9 epoxy resin ine brownish kutsvuka kuti yero uye inogona kuita chena yemukaka kana kupenya mushure memvura.
Petroleum resin inonyanya kushandiswa mumachira ekuvaka, anonamira, inki kudhinda, kuchengetedza, uye vulcanized rabha yakagadziridzwa zvinhu. Nekuenderera mberi kwekusimudzira tekinoroji resin, mashandisiro ayo makuru ari kuramba achikura. C5 epoxy resin iboka rine kukurumidza kusimudzira maitiro panguva ino, uye inoshandiswa zvakanyanya mukuvaka machira, kudhinda ingi, kuisa chisimbiso, bonding uye mamwe maindasitiri. C9 epoxy resin inoshandiswa zvakanyanya mupendi, vulcanized rabha, mapurasitiki nemamwe maindasitiri, uye kukura kwayo uye dhizaini tarisiro yemusika yakakura kwazvo.
