I-petroleum resin (i-hydrocarbon resin)
I-petroleum resin ingumkhiqizo wamakhemikhali osanda kuthuthukiswa eminyakeni yamuva nje. Iqanjwe ngegama lomthombo we-petroleum derivatives. Inezici zenani eliphansi le-asidi, ukungahambi kahle kahle, ukumelana namanzi, ukumelana ne-ethanol kanye nokumelana namakhemikhali, kanye nokuzinza okuhle kwamakhemikhali ku-asidi ne-alkali. , futhi inokulungiswa okuhle kwe-viscosity nokuzinza kokushisa, intengo ephansi. Ama-petroleum resins ngokuvamile awasetshenziswa wodwa, kodwa asetshenziswa ndawonye njengama-accelerator, izilawuli, izilungisi kanye nezinye izinsimbi. Isetshenziswa kakhulu ku-raber, izinto zokunamathisela, okokunamathela, amaphepha, uyinki nezinye izimboni namasimu.
Ngokuvamile, ingahlukaniswa njenge-C5 aliphatic, i-C9 enuka kamnandi (i-aromatic hydrocarbons), i-DCPD (cycloaliphatic, cycloaliphatic) kanye nama-monomers amsulwa njenge-poly SM, AMS (alpha methyl styrene) nezinye izinhlobo ezine zemikhiqizo, Ama-molecule awo wonke angama-hydrocarbon. , ngakho-ke ibizwa nangokuthi i-hydrocarbon resins (HCR).
Ngokwezinto zokusetshenziswa ezihlukene, ihlukaniswe nge-Asiatic resin (C5), i-alicyclic resin (DCPD), i-aromatic resin (C9), i-aliphatic/aromatic copolymer resin (C5/C9) kanye ne-hydrogenated petroleum resin. I-C5 hydrogenated petroleum resin, i-C9 hydrogenated petroleum resin
Ezisetshenziswa kakhulu yilezi
I-C9 petroleum resin isho ngokuqondile into ekhipha inhlaka etholwe "nge-polymerizing olefin noma i-cyclic ole fins noma i-copolymerizing nge-aldehydes, ama-hydrocarbon aphunga, i-terpenes, njll." equkethe ama-athomu e-carbon ayisishiyagalolunye.
I-C9 petroleum resin, eyaziwa nangokuthi i-resin enamakha, ihlukaniswe nge-polymerization eshisayo, i-polymerization ebandayo, itiyela njalonjalo. Phakathi kwazo, umkhiqizo obandayo we-polymerization unombala okhanyayo, omuhle ngekhwalithi, futhi unesisindo samangqamuzana angama-2000-5000. I-flake eliphuzi ngokukhanyayo ukuya ku-brown ngokukhanyayo, i-granular noma eqinile enkulu, esobala futhi ecwebezelayo, ukuminyana okuhlobene 0.97~1.04.
Iphoyinti lokuthambisa ngu-80~140â. Izinga lokushisa lokushintsha kwengilazi lingu-81°C. Inkomba ye-Refractive 1.512. Iphoyinti elikhanyayo 260 â. Inani le-Acid 0.1~1.0. Inani le-iodine lingu-30~120. Incibilika ku-acetone, i-methyl ethyl ketone, i-cyclohexane, i-dichloroethane, i-ethyl acetate, i-toluene, uphethiloli, njll.
Ayincibiliki ku-ethanol nasemanzini. Inokwakheka kwe-cyclic, iqukethe amabhondi aphindwe kabili, futhi inokuhlangana okuqinile. Awekho amaqembu e-polar noma asebenzayo esakhiweni samangqamuzana futhi awekho umsebenzi wamakhemikhali. Inokumelana okuhle ne-asidi ne-alkali, ukumelana namakhemikhali nokungangeni kwamanzi.
Ukunamathela okungalungile, ukubola, nokungagugi kahle, akufanele kusetshenziswe yedwa. Ukuhambisana kahle ne-phenolic resin, i-coumarone resin, i-terpene resin, i-SBR, i-SIS, kodwa ukungahambisani kahle nama-polymer angewona ama-polar ngenxa ye-polarity ephezulu. Okuvutha umlilo. Ayinabuthi.
Ngamandla ayo okuxebuka nokubopha okuphezulu, ukuthambekela okuhle okusheshayo, ukusebenza okuzinzile kwesibopho, i-viscosity encibilikayo emaphakathi, ukumelana nokushisa okuhle, ukuhambisana kahle ne-polymer matrix, kanye nenani eliphansi, yaqala ukushintsha kancane kancane inhlaka yemvelo ukuze kwandiswe ama-viscosity agents (i-rosin ne-terpene resins). ).
Izici ze-C5 petroleum resin ecwengiwe ezinamathelayo ezincibilikayo ezishisayo: ukumanzi kahle, kungathuthukisa ukumanzisa kwezinto eziyinhloko, i-viscosity enhle, nokusebenza okuvelele kokuqala kwe-tack. Izakhiwo ezinhle kakhulu zokulwa nokuguga, umbala okhanyayo, obala, iphunga eliphansi, ama-volatiles aphansi. Kuzinto zokunamathisela ezincibilikayo ezishisayo, uchungechunge lwe-ZC-1288D lungasetshenziswa lodwa njenge-resin yokuthinta noma luxutshwe namanye ama-resin wokudonsa ukuze kuthuthukiswe izici ezithile zokunamathela okuncibilika okushisayo.
Okunamathelayo okuncibilika okushisayo:
I-resin eyisisekelo ye-adhesive encibilikayo eshisayo i-ethylene ne-vinyl acetate copolymerized ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu, okuyi-resin EVA. Le resin iyingxenye eyinhloko yokwenza ingcina encibilikayo eshisayo. Ingxenye kanye nekhwalithi ye-resin eyisisekelo inquma izici eziyisisekelo ze-adhesive encibilikayo eshisayo.
I-Melt index (MI) 6-800, okuqukethwe kwe-VA ephansi, ukuphakama kwekristalu, ukuphakama kokuqina, ngaphansi kwezimo ezifanayo, kukhulu okuqukethwe kwe-VA, i-crystallinity ephansi, amandla aphezulu anwebekayo kanye nezinga lokushisa elincibilikayo. impofu ekumanzini nasekungeneni kokunamathelayo.
Ngokuphambene nalokho, uma inkomba yokuncibilika inkulu kakhulu, izinga lokushisa elincibilikayo leglue liphansi, i-fluidity inhle, kodwa amandla okubopha ayancipha. Ukukhethwa kwezithasiselo zayo kufanele kukhethe isilinganiso esifanele se-ethylene ne-vinyl acetate.
Ezinye izinhlelo zokusebenza:
1. Upende
Upende ngokuyinhloko usebenzisa i-C9 petroleum resin, DCPD resin kanye ne-C5/C9 copolymer resin enephoyinti lokuthambisa eliphakeme. Ukwengeza i-petroleum resin kupende kungandisa ukucwebezela kopende, kuthuthukise ukunamathela, ukuqina, ukumelana ne-asidi kanye nokumelana ne-alkali kwefilimu kapende.
2. Irabha
Irabha ikakhulukazi isebenzisa indawo ephansi yokuthambisa i-C5 petroleum resin, C5/C9 copolymer resin kanye ne-DCPD resin. Ama-resin anjalo anokuncibilika okuhle okuhambisanayo nezinhlayiya zenjoloba zemvelo, futhi azinawo umthelela omkhulu enqubweni ye-vulcanization yenjoloba. Ukwengeza i-petroleum resin kwirabha kungakhuphula i-viscosity, kuqinise futhi kuthambe. Ikakhulukazi, ukungezwa kwe-C5/C9 copolymer resin akukwazi nje ukwandisa ukunamathela phakathi kwezinhlayiya zenjoloba, kodwa futhi kuthuthukise ukunamathela phakathi kwezinhlayiya zenjoloba nezintambo. Ifanele imikhiqizo yenjoloba enezidingo eziphezulu ezifana namathayi e-radial.
3. Imboni yokunamathisela
I-petroleum resin inokunamathela okuhle. Ukwengeza i-petroleum resin kuma-adhesives kanye namateyipu azwela ukucindezela kungathuthukisa amandla okunamathela, ukumelana ne-asidi, ukumelana ne-alkali kanye nokumelana namanzi kokunamathelayo, futhi kunganciphisa ngempumelelo izindleko zokukhiqiza.
4. Imboni kayinki
Ama-petroleum resin
5. Imboni yokumboza
Izembatho zezimpawu zomgwaqo nokumaka komgwaqo, i-petroleum resin inokunamathela okuhle kukhonkolo noma i-asphalt pavement, futhi inokumelana nokugqokwa okuhle nokumelana namanzi, futhi inobudlelwano obuhle nezinto ezingaphili, ukugqokwa kalula, ukumelana nesimo sezulu esihle,
Ukoma okusheshayo, ukuqina okuphezulu, futhi kungathuthukisa izakhiwo ezingokomzimba nezamakhemikhali zongqimba, kuthuthukise ukumelana ne-UV kanye nokumelana nesimo sezulu. Upende wokumaka womgwaqo we-petroleum resin uya ngokuya usetshenziswa, futhi isidingo sikhula unyaka nonyaka.
6. Abanye
I-resin inezinga elithile le-unsaturation futhi ingasetshenziswa njenge-ejenti yokulinganisa iphepha, isilungisi sepulasitiki, njll.
7.
Gcina endaweni engenawo umoya, epholile futhi eyomile. Isikhathi sokugcina ngokuvamile unyaka owodwa, futhi singasetshenziswa ngemva konyaka owodwa uma sidlula ukuhlolwa.
