Xabagta batroolka (resin hydrocarbon)
Xabagta batroolku waa badeeco cusub oo kiimiko ah oo dhawaan la sameeyay. Waxaa loogu magac daray isha laga helo batroolka. Waxay leedahay sifooyinka qiimaha hooseeya ee aashitada, qallafsanaanta wanaagsan, caabbinta biyaha, caabbinta ethanol iyo caabbinta kiimikada, iyo xasilloonida kiimikada wanaagsan ee acid iyo alkali. , oo leh hagaajinta viscosity wanaagsan iyo xasilloonida kulaylka, qiimo jaban. Xabagta batroolka guud ahaan keligood looma isticmaalo, laakiin waxaa si wada jir ah loo isticmaalaa dardar-geliyayaal, nidaamiyayaal, wax-bedeyaal iyo resin kale. Si ballaaran loo isticmaalo caag, xabag, dahaar, warqad, khad iyo warshado iyo beero kale.
Guud ahaan, waxaa loo kala saari karaa sida C5 aliphatic, C9 aromatic (hydrocarbons caraf udgoon), DCPD (cycloaliphatic, cycloaliphatic) iyo monomers saafi ah sida poly SM, AMS (alpha methyl styrene) iyo afar nooc oo kale oo alaabta. , sidaas darteed waxaa sidoo kale loo yaqaannaa hargabka hydrocarbon (HCR).
Marka loo eego alaabta ceeriin ee kala duwan, waxa loo kala qaybiyaa resin Asiatic (C5), resin alicyclic (DCPD), resin aromatic (C9), resin aliphatic/aromatic copolymer (C5/C9) iyo resin batroolka hydrogenated. C5 xabagta batroolka ee hydrogenated, C9 xabagta batroolka ee hydrogenated
Kuwa ugu badan ee la isticmaalo waa
Xabagta batroolka ee C9 waxay si gaar ah u tixraacaysaa walax xabagta leh oo laga helay "polymerizing olefins ama fins ole cyclic or copolymerizing with aldehydes, hydrocarbons caraf udgoon, terpenes, iwm." ka kooban sagaal atamka kaarboon.
Xabagta batroolka ee C9, oo sidoo kale loo yaqaan resin caraf udgoon, ayaa loo qaybiyaa polymerization kuleyl, polymerization qabow, daamur iyo wixii la mid ah. Waxaa ka mid ah, sheyga polymerization-ka qabow waa midab khafiif ah, tayo fiican leh, wuxuuna leeyahay celceliska miisaanka molecular ee 2000-5000. Jaalle khafiif ah ilaa bunni khafiif ah, granular ama adag adag, hufan oo dhalaalaya, cufnaanta qaraabo 0.97 ~ 1.04.
Barta jilicsan waa 80 ~ 140â. Heerkulka kala-guurka dhalada waa 81°C. Tusmada dib-u-celinta 1.512. Dhibicda Flash 260 â. Qiimaha acid 0.1 ~ 1.0. Qiimaha iodine waa 30-120. Ku milmay acetone, methyl ethyl ketone, cyclohexane, dichloroethane, ethyl acetate, toluene, gaaska, iwm.
Aan ku milmin ethanol iyo biyaha. Waxa ay leedahay qaab-dhismeedka meerto, waxa ay ka kooban tahay qaar ka mid ah bonds double, oo ay leedahay isku xirnaan adag. Ma jiraan koox dabley ah ama kooxo shaqaynaya oo ku jira qaab-dhismeedka molecular mana jiraan wax dhaqdhaqaaq kiimiko ah. Waxay leedahay iska caabin wanaagsan oo aysiidh iyo alkali ah, caabbinta kiimikada iyo iska caabinta biyaha.
Ku dheggan liidata, jajaban, iyo caabbinta gabowga liidata, waa inaan keligiis la isticmaalin. Ku habboonaanta wanaagsan ee xabagta phenolic, resin coumarone, resin terpene, SBR, SIS, laakiin ku habboonaanta liidata ee polymers-ka aan polarka ahayn sababtoo ah polarity sare. guban kara Aan sun ahayn
Iyada oo ay ku jirto diirinta sare iyo xoogga isku-xidhka, taako wanaagsan oo degdeg ah, waxqabadka isku xirnaanta xasilloon, dhalaalka dhexdhexaadka ah, caabbinta kulaylka wanaagsan, ku habboonaanta matrix polymer, iyo qiimaha hooseeya, waxay bilowday inay si tartiib tartiib ah u bedesho resin dabiiciga ah si loo kordhiyo wakiilada viscosity (rosin iyo terpene resins). ).
Astaamaha xabagta batroolka ee la safeeyey ee C5 ee xabagta dhalaalaysa ee kulul: Dheecaan wanaagsan, waxay hagaajin kartaa qoyaanka walxaha ugu muhiimsan, viscosity wanaagsan, iyo waxqabadka bilowga ah ee heersare ah. Sifooyin heer sare ah oo ka-hortagga gabowga, midabka iftiinka, hufan, ur hooseeya, kacsanaan hooseeya. Xabagta dhalaalaysa ee kulul, taxanaha ZC-1288D waxa keligiis loo isticmaali karaa sidii resin-ka wax lagaga qaban lahaa ama lagu qasi karo resins kale oo tackifying si loo hagaajiyo sifooyinka qaarkood ee xabagta dhalaalka kulul.
Xabag dhalaalaysa kulul:
Xabagta aasaasiga ah ee xabagta dhalaalaysa kulul waa ethylene iyo vinyl acetate koobiyeerka hoostiisa heerkulka sare iyo cadaadiska sare, kuwaas oo ah EVA resin. Xabagtani waa qaybta ugu muhiimsan ee samaynta xabagta dhalaalaysa ee kulul. Saamiga iyo tayada resin-ka aasaasiga ah ayaa go'aamiya sifooyinka aasaasiga ah ee koollada kulul ee kulul.
Melt index (MI) 6-800, maadada VA hoose, heerka sare ee crystallinity, sare u engegnaanta, xaaladaha isku mid ah, ka weyn ee content VA, hoose crystallinity, ka laastikada ah xoog sare iyo heerkulka dhalaalaysaa sare sidoo kale waa liidata qoynta iyo dabar goynta adherends.
Taas beddelkeeda, haddii tusaha dhalaalku uu aad u weyn yahay, heerkulka dhalaalka ee koollada ayaa hooseeya, dareeraha ayaa wanaagsan, laakiin xoogga isku-xidhka ayaa hoos u dhacaya. Xulashada waxyaabaha lagu daro waa inay doortaan saamiga ku habboon ee ethylene iyo vinyl acetate.
Codsiyada kale:
1. Rinjiyeynta
Rinjiga inta badan wuxuu isticmaalaa xabagta batroolka ee C9, resin DCPD iyo C5/C9 resin copolymer ah oo leh bar jilciya sare. Ku darista resin batroolka rinjiga waxay kordhin kartaa dhalaalka rinjiga, hagaajinta xabagta, adkaanta, caabbinta aashitada iyo caabbinta alkali ee filimka rinjiga.
2. caag
Rubber inta badan waxay isticmaashaa barta jilicsan ee C5 resin petroleum, C5/C9 resin copolymer iyo resin DCPD. Resins-yada noocan oo kale ah waxay leeyihiin isku-dhafan wanaagsan oo leh qaybo caag dabiici ah, oo aan saameyn weyn ku yeelan habka vulcanization ee caag. Ku darista xabagta batroolka ee caagga ah waxay kordhin kartaa viscosity, xoojinta iyo jilicsanaanta. Gaar ahaan, ku-darka C5/C9 copolymer resin kaliya ma kordhin karto isku-xidhka u dhexeeya qaybaha caagga ah, laakiin sidoo kale waxay hagaajinaysaa adhesion u dhexeeya qaybaha caagga ah iyo xadhkaha. Waxay ku habboon tahay alaabooyinka caagga ah ee leh shuruudaha sare sida taayirada radial.
3. Warshadaha dhejiska
Xabagta batroolku waxay leedahay xabag wanaagsan. Ku darista xabagta batroolka ee xabagta iyo cajaladaha xasaasiga ah ee cadaadiska ayaa hagaajin kara xoogga xabagta, caabbinta aashitada, caabbinta alkali iyo caabbinta biyaha ee koollada, waxayna si wax ku ool ah u yareyn kartaa qiimaha wax soo saarka.
4. Warshadaha khadadka
Xabagta batroolka
5. Warshadaha dahaarka
Dahaarka calaamadaha waddooyinka iyo calaamadaynta waddooyinka, xabagta batroolka waxay si fiican ugu dheggan tahay laamiga shubka ah ama daamurka, waxayna leedahay caabbinta xirashada wanaagsan iyo caabbinta biyaha, waxayna leedahay xiriir wanaagsan oo leh walxo aan organic ahayn, fudud in la daboolo, caabbinta cimilada wanaagsan.
Qalajinta degdega ah, adkaanta sare, waxayna hagaajin kartaa sifooyinka jirka iyo kiimikada lakabka, hagaajinta caabbinta UV iyo caabbinta cimilada. Rinjiga caarada batroolka ayaa si tartiib tartiib ah u noqonaya mid caadi ah, dalabkuna wuu sii kordhayaa sanadba sanadka ka dambeeya.
6. Kuwo kale
Resin waxa uu leeyahay shahaado gaar ah oo unsaturation waxaana loo isticmaali karaa sidii wakiilka cabbirka warqadda, beddelka caagga ah, iwm.
7.
Ku kaydi meel hawo leh, qabow oo qalalan. Muddada kaydinta guud ahaan waa hal sano, welina waa la isticmaali karaa hal sano ka dib haddii ay ka gudubto kormeerka.
