1. Nta
TPE hnab looj tes muaj cov yam ntxwv ntawm kev laus tsis kam, siab elasticity thiab roj tsis kam, thiab yooj yim rau txheej txheem thiab tsim;CPE hnab looj tes muaj cov yam ntxwv ntawm tus nqi qis, softness thiab daim ntawv thov ntau yam.
2. Kev nyab xeeb
CPE hnab looj tes tuaj yeem yooj yim decompose hydrogen chloride gas ntawm 50 ℃, uas yog teeb meem rau tib neeg lub cev.Cov txheej txheem tsim khoom thiab kev ua haujlwm yuav ua rau ib puag ncig, thiab kev nyab xeeb yog tsawg;TPE hnab looj tes yog ib yam khoom tiv thaiv ib puag ncig, uas tuaj yeem siv thiab rov siv dua.Nws yuav tsis tawm toxicity nyob rau hauv qhov kub thiab txias, thiab nws muaj kev nyab xeeb dua rau cov neeg siv.
Qhov sib txawv ntawm TPE, CPE thiab TPU:
Cov ntaub ntawv tseem ceeb ntawm CPE hnab looj tes yog LDPE, LLDPE, mLLDPE, thiab lwm yam.
Tpe-thermoplastic elastomer yog ib yam khoom tshiab uas muaj elasticity siab, siab zog thiab siab resilience ntawm roj hmab.
TPU yog cov thermoplastic polyurethane elastomer, uas tuaj yeem muab faib ua TPE thermoplastic elastomer.
Lub resilience thiab hnav tsis kam ntawm TPU zoo dua li ntawm TPE, uas yog vim qhov sib txawv ntawm cov qauv molecular.Tsis tas li ntawd, lub microstructure thiab cov khoom ntawm TPE blends yog qis dua cov TPU blends.Cov khoom siv ntau yam ntawm TPE yuav muaj kev cuam tshuam tsis zoo rau nws qhov kev ua haujlwm zoo.Tshwj xeeb tshaj yog rau TPE nrog siab hardness, ib tug loj feem ntawm polypropylene tivthaiv ua rau lub resilience ntawm TPE zoo heev txo, thiab cov khoom yog nquag deformation nyob rau hauv lub nruam kev txiav txim ntawm sab nraud quab yuam.
Tes xav: TPU muaj qhov hnav tsis kam, muaj zog tes txhuam thiab tsis zoo smoothness.
TPE: vim qhov hloov pauv ntawm cov saw hlau molecular ntawm SEBS, cov khoom zoo li mos, xis thiab du
Kev xav ntawm CPE zoo ib yam li TPE.CPE zaj duab xis ua los ntawm embossing cov menyuam muaj kev ntxhib los mos thiab tuab dua.
Nta:TPE hnab looj tes muaj cov yam ntxwv ntawm kev laus tsis kam, siab elasticity thiab roj tsis kam, thiab yooj yim rau txheej txheem thiab tsim;
Cov khoom siv TPE muaj qhov muag muag, huab cua zoo thiab tsis muaj plasticizer.Nws yog ib puag ncig tus phooj ywg thiab tsis muaj tshuaj lom nrog tus nqi ntawm 20000-50000 / tuj.Nws yog dav siv nyob rau hauv niaj hnub tsim nyog nyob rau hauv kev sib cuag nrog tib neeg lub cev.Vim tias TPE pov tseg tuaj yeem ua 100% rov ua dua tshiab, txuag nqi, yooj yim tsim thiab ua, thiab tsis muaj vulcanization, nws tuaj yeem ua tiav los ntawm cov tshuab thermoplastic molding.Cov txheej txheem muaj xws li txhaj tshuaj molding, extrusion, tshuab moulding, calendering, thiab lwm yam.
CPE hnab looj tes yog pheej yig, mos thiab dav siv
