I-petroleum resin iwuhlobo lwe-epoxy resin enesisindo esiphansi samangqamuzana. Isisindo samangqamuzana ngokuvamile singaphansi kuka-2000. Ine-thermal ductility futhi ingancibilikisa izincibilikisi, ikakhulukazi izincibilikisi zemvelo ezisuselwa kuwoyela ongahluziwe. Inokuhambisana okuhle nezinye izinto ze-resin. Inokwazi ukumelana nokuhuzuka kwekhwalithi ephezulu kanye nokumelana nokuguga. Imingcele yokusebenza kwayo ebalulekile ihlanganisa indawo yokuthambisa, i-hue, i-unsaturation, inani le-asidi, inani le-saponification, ukuminyana okuhlobene, njalonjalo.
Iphuzu lokuthambisa liyisici esiyinhloko se-petroleum resin, okusho ukuthi amandla ayo, ukuqina kwayo, kanye ne-viscosity kuyahlukahluka ngokusetshenziswa, futhi iphuzu elidingekayo lokuthambisa lihlukile. Ngaphansi kwezimo ezijwayelekile, indawo yokuthambisa ekukhiqizweni kwezimboni zenjoloba eshisiwe ingu-70°C kuya ku-1000°C, futhi indawo yokuthambisa ekukhiqizweni kwezimboni zama-coatings nopende ngu-100°C kuya ku-1200°C.
Ngaphezu kwalokho, izinga lokushintsha kwe-tonal okubangelwa ukukhanya kwe-ultraviolet nemiphumela yokushisa nakho kuyipharamitha yokusebenza ebaluleke kakhulu. Inani le-asidi lingasetshenziswa hhayi kuphela ukuthola amandla okugcina ama-acid-base metal catalysts kodwa futhi nokuthola izingxenye ze-carbonyl ne-carboxyl zesitoreji se-petroleum resin ngenxa ye-oxidation yayo.
Ukwakheka kwe-petroleum resin kuyinkimbinkimbi kakhulu. Ngokumaketha nokukhuthazwa kokusetshenziswa kwayo okuyinhloko, kunezinhlobo eziningi kakhulu, ezingahlukaniswa ngokwezigaba ezinhlanu:
â Amafutha omzimba womuntu, i-cycloaliphatic epoxy resin, ngokuvamile elungiswa kusukela ku-C5 fraction, eyaziwa nangokuthi i-C5 epoxy resin;
â¡ p-xylene epoxy resin, ngokuvamile eyenziwe nge-C9 fraction, eyaziwa nangokuthi i-C9 epoxy resin;
⢠i-p-xylene-aliphatic hydrocarbon copolymer epoxy resin, eyaziwa nangokuthi i-C5/C9 epoxy resin;
â£I-Dicyclopentadiene epoxy resin, eyenziwe nge-dicyclopentadiene noma izinhlanganisela zayo, futhi ibizwa nge-DCPD epoxy resin. Ngenxa yokuthi le resin ye-epoxy inamaqembu e-aliphatic hydrocarbon engagcwalisiwe, ibizwa nangokuthi iringi ekhanyayo ye-Oxygen resin.
⤠I-Hydrocracking petroleum resin, ngokuvamile i-C5 noma i-C9 epoxy resin inombala onsundu ngokubomvu ukuya kokuphuzi ngokukhanyayo futhi ingaba mhlophe njenge-milky noma ikhanye ngemva kwe-hydrocracking.
I-petroleum resin isetshenziswa kakhulu ekuhlanganiseni kwezakhiwo, izinto zokunamathisela, ukuphrinta uyinki, izilondolozi, nezinto eziguquliwe zenjoloba. Ngomkhuba wokuthuthuka oqhubekayo wobuchwepheshe be-resin, ukusetshenziswa kwayo okuyinhloko nakho kuthuthuka njalo. I-C5 epoxy resin iyisigaba esinomkhuba wokuthuthuka ngokushesha kulesi sigaba, futhi isetshenziswa kabanzi embotsheni yezakhiwo, oyinki bokuphrinta, ukuvala, ukubopha nezinye izimboni. I-C9 epoxy resin isetshenziswa kakhulu kupende, irabha eshisiwe, ipulasitiki nezinye izimboni, futhi ukuthuthukiswa kwayo kanye nokuklama kwayo kwemakethe kubanzi kakhulu.
