Elastomers yog cov khoom siv uas muaj nyob rau hauv peb lub neej txhua hnub. Lawv sawv tawm ntawm lawv qhov kev hloov siab heev thiab vim tias lawv tuaj yeem siv rau ntau cov kev siv. Thermoplician Polyurethane Polyurethane (TPU) yog undoubtedly cov khoom siv feem ntau vim nws cov versatility.
Thermoplastic Polyurethane (TPU): Dab tsi yog nws thiab nws siv rau dab tsi?
TPU (Thermoplastic Polyurethane) is tsuas yog ib qho ntawm ntau yam ntawm polyurethane. Nws yog melt-cov txheej txheem thermoplastic elastomer nrog kev hloov kho tau zoo heev, qhov kav ntev, thiab tua tsis tawm. Zoo li lwm yam thermoplastics zoo li, nws yog tsim los ntawm kev txhaj tshuaj molding, tshuab moulding thiab extrusion.
Hais txog cov ntawv thov, nws yog cov khoom siv uas tuaj yeem pom nyob hauv cov rooj tog zaum, tsheb, lub cev, khau, thiab cov xim nplaum, xim av,ywj textile fibers, cov log, lub xov tooj txawb, cable sheathing,Cov Khoom Siv Ua Si, cov cuab yeej siv tshuab thiab cov khoom siv hoses, qhov chaw, khoom siv hluav taws xob, cov khoom siv rau kev ua liaj ua teb, ua liaj ua teb thiab nuv ntses, thiab lwm yam.
COMPOSITION NTAWM TPU
Thermoplastrastic polyurethane yog tau los ntawmcov tshuaj tiv thaiv ntawm polyols(Polyester Polyether lossis Polycarbonate raws),Diisocyanates thiab luv-saw diols.Cov khoom ntxiv tuaj yeem muab ntxiv rau cov no kom ua tiav cov khoom tshwj xeeb. Los ntawm kev sib txuas tag nrho cov khoom, muaj ntau yam ntawm hardness thiab cov neeg kho tshuab tuaj yeem ua tiav.
Ib qho ntxiv, TPU muaj lwm yamCov ntu ntawm cov tawv thiab cov plaub ntu muag, uas ua rau muaj kev yoog raws siab. Los ntawm kev tswj hwm qhov sib piv ntawm cov ntu no, ntau yam sib txawv ntawm kev tawv tawv tuaj yeem tau txais. Cov ntu nyuaj ntxiv, Stiffer lub TPU yuav.
Qhov zoo dua lwm cov ntaub ntawv
Thermoplastic Polyurethane tsis kam, yog nplaim taws retardant, yog zoo li ultraviolet rays thiab hydrolysis tsis kam. Nws sawv tawm rau nws cov kav ntev,siab damping muaj peev xwm thiab kev tawm tsam rau deformation,zoo dua rau lwm cov ntaub ntawv.
Ntxiv mus, Thermoplastic Polyurethaneyogrov dua,Tsis zoo li cov roj hmab, uas tsis yaj thaum ua kom sov. Nws tseem yuav siv lub zog tsawg dua rau cov txheej txheem dua li thermoset elastomers, thiab tsis tas yuav tsum muaj tshwj xeebNtxiv rau cov txheej txheem, raws li silicones thiab rubbers ua. Nyob rau hauv cov ntaub ntawv silicones thiab rub, txhawb cov neeg sawv cev, stabilizers thiab kho reagents yuav tsum tau ntxiv.
TPU yog cov khoom siv nyob ntev vim tias nwsmuaj cov tshuaj cam lossis cov tshuaj cam tsis muaj cov khoom lag luam halogenatedCov. Nws tseem ceev rau cov txheej txheem, uas txo nws cov nqi tsim khoom. Nwstuaj yeem tau xim yooj yimnrog feem ntau cov pigments, thiab lwm tus ntawm nws cov txiaj ntsig yog qhov zooKev tswj cov khoom kawg yog qhov yooj yim thiab raug nqi.
