Iintlaka zepetroleum (i-hydrocarbon resin)
I-petroleum resin yimveliso yekhemikhali esandula ukwenziwa kwiminyaka yakutshanje. Ithiywe ngegama lomthombo wepetroleum derivatives. Ineempawu zexabiso le-asidi ephantsi, ukungahambi kakuhle, ukuxhathisa kwamanzi, ukuxhathisa kwe-ethanol kunye nokuchasana kweekhemikhali, kunye nokuzinza kweekhemikhali ezilungileyo kwi-asidi kunye ne-alkali. , kwaye inokulungiswa kakuhle kwe-viscosity kunye nokuzinza kwe-thermal, ixabiso eliphantsi. I-petroleum resins ngokuqhelekileyo ayisetyenziswanga yodwa, kodwa isetyenziswa kunye njenge-accelerators, i-regulators, i-modifiers kunye nezinye ii-resin. Isetyenziswa kakhulu kwirabha, izinto zokuncamathelisa, iingubo, iphepha, i-inki kunye namanye amashishini kunye namasimi.
Ngokubanzi, inokuhlelwa njenge-C5 aliphatic, i-C9 enuka kamnandi (i-aromatic hydrocarbons), i-DCPD (i-cycloaliphatic, i-cycloaliphatic) kunye ne-monomers ecocekileyo njenge-poly SM, i-AMS (i-alpha methyl styrene) kunye nezinye iintlobo ezine zeemveliso, iimolekyuli eziyinxalenye yazo zonke ziyi-hydrocarbons. , ngoko ikwabizwa ngokuba yi-hydrocarbon resins (HCR).
Ngokwezinto eziluhlaza ezahlukeneyo, zohlulwe kwi-Asiatic resin (C5), i-alicyclic resin (DCPD), i-resin enuka kamnandi (C9), i-aliphatic/aromatic copolymer resin (C5/C9) kunye ne-hydrogenated petroleum resin. I-C5 i-hydrogenated petroleum resin, i-C9 i-hydrogenated petroleum resin
Ezona zisetyenziswa kakhulu zi
I-C9 petroleum resin ibhekisa ngokuthe ngqo kwi-resinous substance efunyenwe "nge-polymerizing olefins okanye i-cyclic ole fins okanye i-copolymerizing nge-aldehydes, i-hydrocarbons enuka kamnandi, i-terpenes, njl." iqulethe iiathom zekhabhoni ezisithoba.
I-C9 petroleum resin, ekwabizwa ngokuba yiresin enevumba elimnandi, yohlulwe ibe yi-polymerization eshushu, i-polymerization ebandayo, itela njalo njalo. Phakathi kwabo, imveliso ye-polymerization ebandayo ilula ngombala, ilungile kumgangatho, kwaye inomlinganiselo we-molecular weight 2000-5000. Iflake elityheli elikhanyayo ukuya kumdaka okhanyayo, igranular okanye ukuqina okukhulu, okubonakalayo kunye nokucwebezela, ukuxinana okunxulumene 0.97 ~ 1.04.
Indawo yokuthambisa yi80~140â. Ubushushu bokutshintsha kweglasi yi-81°C. Isalathiso seRefractive 1.512. Indawo edanyazayo 260 â. Ixabiso leasidi 0.1~1.0. Ixabiso le-iodine yi-30~120. I-Soluble kwi-acetone, i-methyl ethyl ketone, i-cyclohexane, i-dichloroethane, i-ethyl acetate, i-toluene, i-petroli, njl.
Ayinyibiliki kwi-ethanol nasemanzini. Inesakhiwo se-cyclic, iqulethe ezinye iibhondi eziphindwe kabini, kwaye inokubambisana okuqinileyo. Akukho maqela e-polar okanye asebenzayo kwisakhiwo se-molecular kwaye akukho msebenzi wamachiza. Inokumelana kakuhle ne-asidi kunye ne-alkali, ukuxhathisa imichiza kunye nokuxhathisa amanzi.
Ukubambelela kakubi, ukubola, kunye nokunganyangeki ukwaluphala, akufuneki kusetyenziswe yedwa. Ukuhambelana kakuhle ne-phenolic resin, i-coumarone resin, i-terpene resin, i-SBR, i-SIS, kodwa ukungahambelani kakuhle kunye neepolymers ezingezizo ze-polar ngenxa ye-polarity ephezulu. Ukutsha. Ayinatyhefu.
Ngokucocwa okuphezulu kunye namandla okudibanisa, ukucofa okukhawulezileyo, ukusebenza ngokuzinzileyo, i-viscosity ephakathi yokunyibilika, ukumelana nobushushu obulungileyo, ukuhambelana kakuhle ne-polymer matrix, kunye nexabiso eliphantsi, yaqala ukutshintsha ngokuthe ngcembe intlaka yendalo ukunyusa i-viscosity agents (i-rosin kunye ne-terpene resins. ).
Iimpawu ze-C5 ye-petroleum resin ecocekileyo kwi-adhesives ye-melt eshushu: i-fluidity enhle, inokuphucula ukumanzi kwezinto eziphambili, i-viscosity enhle, kunye nokusebenza okubalaseleyo kokuqala. Iimpawu ezigqwesileyo zokuguga, umbala okhanyayo, obala, iphunga eliphantsi, i-volatiles ephantsi. Kwizinto zokuncamathelisa ezinyibilikayo ezitshisayo, uthotho lwe-ZC-1288D lunokusetyenziswa lodwa njenge-resin yokuthintela okanye ixutywe kunye nezinye iireyini zokuthambisa ukuze kuphuculwe iimpawu ezithile zokuncamathelisa ezishushu ezinyibilikayo.
Isincamathelisi sokunyibilika esishushu:
I-resin esisiseko ye-adhesive eshushu enyibilikayo yi-ethylene kunye ne-vinyl acetate copolymerized phantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, oko kukuthi i-EVA resin. Le resin yeyona nto iphambili yokwenza incamathiso enyibilikayo eshushu. Umlinganiselo kunye nomgangatho we-resin esisiseko unquma iimpawu ezisisiseko ze-adhesive eshushu enyibilikayo.
Isalathisi se-Melt (MI) 6-800, umxholo we-VA ophantsi, ukuphakama kwekristali, ukuphakama kobunzima, phantsi kweemeko ezifanayo, umxholo we-VA omkhulu, i-crystallinity ephantsi, i-elastiki ephezulu Amandla aphezulu kunye nobushushu obuphezulu bokunyibilika nazo. ihlwempuzekile ekumanzini kunye nokungena kwamanzi okubambelela.
Ngokuchasene noko, ukuba isalathisi sokunyibilika sikhulu kakhulu, ukushisa okunyibilikayo kweglue kuphantsi, ubuninzi be-fluidity bulungile, kodwa amandla okubambisana ayancipha. Ukukhethwa kwezongezo zayo kufuneka kukhethe umlinganiselo ofanelekileyo we-ethylene kunye ne-vinyl acetate.
Ezinye izicelo:
1. Peyinta
Ipeyinti ikakhulu isebenzisa iC9 petroleum resin, DCPD resin kunye neC5/C9 copolymer resin enendawo ephezulu yokuthambisa. Ukongeza i-petroleum resin kwipeyinti kunokunyusa ukukhanya kwepeyinti, ukuphucula ukunamathela, ukuqina, ukuxhathisa kwe-asidi kunye nokumelana ne-alkali yefilimu yepeyinti.
2. Irabha
Irabha ikakhulu isebenzisa indawo esezantsi yokuthambisa iC5 petroleum resin, C5/C9 copolymer resin kunye neDCPD resin. I-resin ezinjalo zine-solubility efanelekileyo yokubambisana kunye neengqungquthela zerubha zendalo, kwaye azinayo impembelelo enkulu kwinkqubo ye-vulcanization yerabha. Ukongeza i-petroleum resin kwirabha inokunyusa i-viscosity, iqinise kwaye ithambe. Ngokukodwa, ukongezwa kwe-resin ye-C5 / C9 ye-copolymer ayikwazi nje ukunyusa ukudibanisa phakathi kwee-rubber particles, kodwa nokuphucula ukudibanisa phakathi kweerubha kunye neentambo. Ifanelekile kwiimveliso zerabha ezineemfuno eziphezulu ezifana namathaya e-radial.
3. Ishishini lokuncamathelisa
I-petroleum resin inokunamathela okulungileyo. Ukongeza i-petroleum resin kwi-adhesives kunye ne-tapes-sensitive tapes kunokuphucula amandla okubambelela, ukuxhathisa kwe-asidi, ukuxhathisa kwe-alkali kunye nokumelana kwamanzi okunamathela, kwaye kunokunciphisa ngokufanelekileyo iindleko zokuvelisa.
4. Ishishini le-inki
I-petroleum resins
5. Ishishini lokugquma
Iingubo zeempawu zendlela kunye nokumakishwa kwendlela, i-petroleum resin inokubambelela kakuhle kwikhonkrithi okanye kwi-asphalt pavement, kwaye inokumelana nokunxiba kakuhle kunye nokumelana namanzi, kwaye inobudlelwane obuhle kunye nezinto ezingaphiliyo, kulula ukuyinxiba, ukumelana nemozulu entle,
Ukomisa ngokukhawuleza, ukuqina okuphezulu, kwaye kunokuphucula iimpawu zomzimba kunye neekhemikhali zomaleko, ukuphucula ukuxhathisa kwe-UV kunye nokumelana nemozulu. Ipeyinti yokumakisha yepeyinti ye-petroleum resin ihamba kancinci kancinci, kwaye imfuno iyanda unyaka nonyaka.
6. Abanye
I-resin inenqanaba elithile lokungasetyenziswa kwaye inokusetyenziswa njenge-arhente yokulinganisa iphepha, isilungisi seplastiki, njl.
7.
Gcina kwindawo engena umoya, epholileyo neyomileyo. Ixesha lokugcinwa ngokubanzi ngunyaka omnye, kwaye isenokusetyenziswa emva konyaka omnye ukuba iphumelele ukuhlolwa.
