Qhov zoo ntawm TPE:
TPE tuaj yeem ua tiav siv cov thermoplastic molding tshuab, xws li txhaj tshuaj molding, extrusion, tshuab moulding, compression molding, thiab hloov molding.
Nws tseem tuaj yeem ua vulcanized nrog lub tshuab roj hmab txhaj tshuaj molding, txo lub sij hawm los ntawm ib ncig ntawm 20 feeb mus rau hauv 1 feeb.
TPE tso cai rau vulcanization ceev thaum lub sij hawm extrusion molding, nrog siab extrusion ceev thiab luv vulcanization sij hawm.
Cov khib nyiab tsim tawm thaum lub sijhawm tsim khoom, xws li flash lossis extruded seem, tuaj yeem rov siv ncaj qha.
Siv cov khoom siv TPE tuaj yeem siv tau yooj yim thiab rov siv dua, txo cov pa phem ib puag ncig thiab nthuav dav cov khoom siv rov ua dua tshiab.
TPE tsis xav tau vulcanization, uas txuag lub zog. Piv txwv li, nyob rau hauv zus tau tej cov high-pressure hoses, lub zog siv rau roj hmab yog 188 MJ / kg, thaum rau TPE, nws yog 144 MJ / kg, uas ua rau ntau tshaj 25% zog txuag.
TPE muaj kev txhawb nqa tus kheej siab, uas ua kom yooj yim formulations, txo qhov cuam tshuam ntawm additives ntawm polymers thiab ua kom zoo tswj tau yooj yim dua.
TPE qhib qhov muaj peev xwm tshiab rau kev lag luam roj hmab, nthuav dav daim ntawv thov kev lag luam ntawm cov khoom siv roj hmab.
TPE Disadvantages:TPE muaj cov cua kub qis dua piv rau cov roj hmab, vim nws cov khoom poob qis nrog qhov kub thiab txias, txwv nws cov kev siv ntau yam. Tsis tas li ntawd, TPE's compression deformation, rebound, thiab durability feem ntau qis dua cov roj hmab, thiab nws feem ntau kim dua li cov khoom siv roj hmab zoo sib xws. Txawm li cas los xij, TPE qhov zoo yog qhov tseem ceeb, thiab nws qhov tsis zoo yog txuas ntxiv txhim kho, ua rau nws muaj txiaj ntsig zoo, txuag hluav taws xob, thiab cov khoom siv ib puag ncig.
PP qhov zoo:
PP muaj qhov ntom ntom tsawg ntawm 0.89-0.91, ua rau nws yog ib qho ntawm cov khoom siv yooj yim tshaj plaws.
PP nthuav tawm cov khoom zoo heev. Ib cag los ntawm kev cuam tshuam tsis zoo, nws lwm yam khoom siv dag zog tshaj cov polyethylene, thiab nws muaj cov pwm zoo thiab ua haujlwm zoo.
PP muaj qhov ua tau zoo rau cov cua sov, nrog rau kev siv qhov kub thiab txias txog li 110-120 degree .
PP qhia cov tshuaj tiv thaiv zoo heev, vim nws yuav luag tsis nqus thiab tsis hnov mob nrog cov tshuaj feem ntau.
PP yog ntshiab thiab tsis muaj tshuaj lom.
PP cov khoom muaj pob tshab zoo dua piv rau cov uas ua los ntawm high-density polyethylene.
PP Disadvantages:
PP cov khoom muaj qhov tsis zoo rau qhov txias txias thiab tsis tshua muaj kev cuam tshuam lub zog ntawm qhov kub thiab txias.
PP feem ntau muaj hnub nyoog qis dua qhov raug lub teeb, tshav kub, thiab oxygen thaum siv.
PP muaj cov xim tsis zoo.
PP yog heev flammable.
PP muaj qhov tsis zoo toughness, siab zoo li qub, thiab txwv dyeing, luam ntawv, thiab adhesion muaj peev xwm.
Ob leeg TPE thiab PP muaj qhov zoo thiab qhov tsis zoo. TPE ua tau zoo hauv kev ua haujlwm zoo thiab ib puag ncig tus phooj ywg, thaum PP yog lub teeb yuag thiab kub-tiv taus.
