I-petroleum resin luhlobo lwe-epoxy resin enobunzima obuphantsi bemolekyuli. Ubunzima bemolekyuli ngokubanzi bungaphantsi kwama-2000. Ine-thermal ductility kwaye inokunyibilikisa izinyibilikisi, ngakumbi izinyibilikisi ezikrwada ezisekwe kwi-oyile ekrwada. Inokuhambelana kakuhle nezinye izinto ze-resin. Inobuganga obuphezulu bokuxhathisa kunye nokumelana nokuguga. Iiparamitha zayo eziphambili zokusebenza ziquka i-softening point, i-hue, i-unsaturation, ixabiso le-asidi, ixabiso le-saponification, ukuxinana kwezihlobo, njalo njalo.
Inqaku lokuthambisa luphawu oluphambili lwe-petroleum resin, oku kuthetha ukuba amandla ayo, i-brittleness, kunye ne-viscosity iyahluka kunye nesicelo, kwaye indawo yokuthambisa efunekayo ikwahluke. Ngaphantsi kweemeko eziqhelekileyo, indawo yokuthambisa kwimveliso ye-industrial yerubha evuthisiweyo yi-70 ° C ukuya kwi-1000 ° C, kwaye indawo yokuthambisa kwimveliso yemveliso yeengubo kunye nepeyinti yi-100 ° C ukuya kwi-1200 ° C.
Ukongezelela, inqanaba lokutshintsha kwetoni okubangelwa ukukhanya kwe-ultraviolet kunye nemiphumo ye-thermal nayo iparameter yokusebenza ebaluleke kakhulu. Ixabiso le-asidi lingasetyenziselwa kuphela ukufumanisa amandla okugcina i-acid-base ye-catalysts yensimbi kodwa kunye nokubona i-carbonyl kunye ne-carboxyl icandelo lokugcinwa kwe-petroleum resin ngenxa ye-oxidation yayo.
Ukuqulunqwa kwe-petroleum resin kunzima kakhulu. Ngokuthengisa kunye nokukhuthazwa kokusetyenziswa kwayo okuphambili, kukho iintlobo ezininzi nangakumbi, ezinokuthi zohlulwe ngokweendidi ezintlanu:
â Amafutha omzimba womntu, i-cycloaliphatic epoxy resin, elungiselelwe ngokubanzi ukusuka kwiqhezu le-C5, ekwaziwa njenge-C5 epoxy resin;
â¡ i-p-xylene epoxy resin, eyenziwe ngokubanzi kwi-C9 fraction, eyaziwa ngokuba yi-C9 epoxy resin;
⢠i-p-xylene-aliphatic hydrocarbon copolymer epoxy resin, ekwaziwa ngokuba yiC5/C9 epoxy resin;
â£I-Dicyclopentadiene epoxy resin, eyenziwe kwi-dicyclopentadiene okanye iikhompawundi zayo, ikwabizwa ngokuba yi-DCPD epoxy resin. Ngenxa yokuba le resin ye-epoxy inamaqela e-aliphatic hydrocarbon engaxutywanga, ikwabizwa ngokuba yiringi ebonakalisa i-Oxygen resin.
⤠I-Hydrocracking petroleum resin, ngokubanzi i-C5 okanye i-C9 epoxy resin ibamdaka obomvu ukuya kumthubi okhanyayo kwaye inokuba mhlophe bubisi okanye i-translucent emva kwe-hydrocracking.
I-petroleum resin isetyenziswa ikakhulu kwiingubo zokwakha, izinto zokuncamathelisa, ushicilelo lwe-inki, izikhuselo, kunye nemathiriyeli eguqulweyo yerabha. Ngophuhliso oluqhubekayo lwetekhnoloji ye-resin, ukusetyenziswa kwayo okuphambili kukwaphuhliswa rhoqo. I-C5 epoxy resin luhlobo olunendlela yophuhliso olukhawulezayo kweli nqanaba, kwaye isetyenziswa ngokubanzi kwiingubo zokwakha, ii-inki zokuprinta, ukutywina, ukubopha kunye namanye amashishini. I-C9 epoxy resin isetyenziswa kakhulu kwipeyinti, irabha evulziweyo, iplastiki kunye namanye amashishini, kwaye uphuhliso lwayo kunye noyilo lwamathemba emarike abanzi kakhulu.
