Pellets caag ah Thermoplastic Polyester Elastomer TPEE

Hordhaca alaabta

Qalabka T hermoplastic Polyester Elastomer (TPEE)
Iyadoo la hagaajinayo saamiga qaybaha jilicsan iyo kuwa adag, adkaanta elastomer polyether ester waxay ka iman kartaa Shore D (32 ilaa 82), bartinimadeeda iyo xooggeeda waxay u dhexeeyaan caag iyo caag. Marka la barbar dhigo elastomeryada kale ee thermoplastic TPE, modules of polyether ester elastomer wuu ka sarreeyaa elastomeryada kale ee heerkulbeegga ah ee leh isla engegnaanta xaaladaha cadaadiska hooseeya. Marka modulesku yahay sharuudaha naqshadeynta ee muhiimka ah, isticmaalka PEEE elastomers waxay yaraynaysaa aagga isdhaafka ah ee alaabta waxayna yaraynaysaa cadadka walxaha la isticmaalo.
Elastomers-ka polyetherther-ka waxay leeyihiin awood cufan oo aad u sarreeya. Marka la barbar dhigo poliurethane (TPU), cufnaanta iyo module-ka jilicsan ee polyether-ester elastomers ayaa aad u sarreeya, marka isla qayb laga sameeyo elastomer polyether-ester oo la mid ah TPU, kii hore wuxuu u adkeysan karaa culeysyo aad u weyn. Xagga sare ee heerkulka qolka, poliether ester elastomer modules foorarsiga waa mid aad u sarreeya, heerkulka hooseeyana maaha sida TPU waa mid aad u adag, sidaas darteed waxay ku habboon tahay wax soo saarka muraayadaha cantilever ama qaybaha nooca torque, gaar ahaan ku habboon wax soo saarka qaybaha heerkulka sare. Dabacsanaanta heerkulka hooseeya ee Polyether ester elastomer waa wanaagsan tahay, heerkulka hooseeya ee saamaynta xoogga leh ayaa ka fiican TPE kale, iska caabbinta abrasion iyo TPU u dhiganta. Xaaladaha cidhiidhiga hooseeya, elastomer polyether ester wuxuu leeyahay iska caabin daal aad u fiican, iyo luminta hysteresis yar, qaabkan oo ay weheliso dabacsanaan sare, samaynta maaddada ayaa noqonaysa qalabka ugu fiican ee xaaladaha isticmaalka badan ee culeyska wareegga, qalabka, rollers caag ah, xirmooyinka dabacsan, suumanka ayaa la isticmaali karaa.
2 Guryaha kulaylka
Elastomers Polyether ester thermoplastic elastomer, haddii aan lagu darin antioxidant, waxay si dhakhso ah u hoos u dhici doontaa xaalado badan, sida buufinta biyaha, ozone, jawiga dibadda, iwm. Falcelintan nabaad-guurka ah ee polyether ester-ka ayaa ah fal-celin xag-jir ah oo xor ah, lagana yaabo inay sabab u tahay silsiladda polymer-ka ee leh atomyada oksijiinta ee polyeter-ka ee ku xidhan atamka kaarboonka ayaa la weeraray, jebinta silsiladda elastomer-ka ee polyether-ka waxa ay abuurtaa formaldehyde, formaldehyde waxa ay oksidhid gelisaa formic acid, iyo aashitada formic iyana waxa ay kor u qaadaa jebinta silsiladda. Si loo hagaajiyo xaalufinta oksaydhka ee elastomer polyether ester, waxaad isticmaali kartaa hababka xasilinta ee habboon, ku dar nidaamka xasilinta waa in lagu daraa wakiilka xagjirka ah ee xorta ah, wakiilka furfuran ee peroxide iyo wakiilka qabashada formaldehyde.
Elastomers Polyether Ester waxay leeyihiin iska caabin kulayl oo aad u fiican, marka ay adkaato adkaanta, ayaa ka sii fiican iska caabbinta kulaylka. Suugaanta ayaa sheegaysa in polyether ester elastomers at 110 ℃ iyo 140 ℃ kulayl joogto ah 10 saacadood asal ahaan miisaan lumis ma jirin, at 160 ℃ iyo 180 ℃ ayaa la kululeeyey 10 saacadood, miisaanka oo yaraada waa 0.05% kaliya iyo 0.1%. Qalooca kuleylka Isothermal wuxuu muujinayaa in elastomer polyether-ka ee 250 ℃ uu bilaabay inuu lumiyo miisaanka, ilaa 300 ℃ miisaanka isugeynta ee 5%, ilaa 400 ℃, dhacdada miisaan lumis weyn, oo sidaas awgeed xadka sare ee isticmaalka polyether ester elastomer heerkulka rinjiga waa mid aad u sarreeya, heerkulka heerkulka hawada sare si loo isticmaalo heerkulka muddada-gaaban. (150 ~ 160 ℃), oo waxay ku jirtaa heerkulka sare iyo hoose ee luminta guryaha farsamada waa yar yahay. elastomer Polyether ester loo isticmaalo in ka badan 120 ℃, ay xoog adag ayaa aad uga sarreeya TPU.
Intaa waxaa dheer, polyether ester elastomer waxay leeyihiin iska caabin heerkul hooseeya oo heer sare ah. Dhibcaha elastomer ee polyether-ka ayaa ka hooseeya -70 ℃, iyo adkaanta hoose, si fiican u adkaysiga qabowga, inta badan polyether ester elastomer waxaa loo isticmaali karaa -40 ℃ waqti dheer. Iyada oo ay ugu wacan tahay waxqabadka dheellitirka ah ee elastomer-ka polyether-ka ee heerkul sare iyo mid hooseeya, kala duwanaanshaheeda heerkulka shaqadu waa mid aad u ballaaran, waxaa loo isticmaali karaa -70 ~ 200 ℃.
3. Kiimikada caabbinta dhexdhexaadka ah
Polyether ester elastomer waxa uu leeyahay iska caabin saliid heer sare ah, heerkulka qolka iska caabin karaa inta badan warbaahinta kiimikada dareere polar (sida acids, alkalis, amines iyo xeryahooda diol), laakiin doorka hydrocarbons halogenated (marka laga reebo Freon) iyo phenols laakiin ma caawin karo, iyo awoodda ay u leeyihiin in ay iska caabiyaan kiimikooyinka korodhka ee engegnaantiisa iyo hagaajinta. Polyether ester elastomer inta badan dareerayaasha organic, shidaalka iyo gaasaska, iyo guryaha ka-hortagga kala diridda iyo ka-hortagga ka-hortagga waa wanaagsan tahay, shidaalku waa neoprene oo keliya, chlorosulphonated polyetylen, caag nitrile ah iyo caag kale oo saliid u adkaysta, sida 1/3 ~ 1/300.
Si kastaba ha ahaatee, elastomers-ka polyether-ka ayaa leh kulayl liita iyo iska caabbinta biyaha, iyo ku darida stabilizers polycarbonide waxay si weyn u wanaajin kartaa iska caabbinta hydrolysis. Waxaa lagu soo waramayaa in hordhaca PEN ama PCT ee qaybta adag ee PBT ee silsiladda molecular ee polyether ester elastomer ay heli karto elastomer polyeter ester leh biyo ka fiican iyo caabbinta kulaylka.
