Hloov kho PP rau Kev Txhaj Tshuaj Loj thiab Tsis Yooj Yim -Moulded Parts
Polyolefin compound nyob rau hauv cov khoom no yog hais txog cov khoom ntim polypropylene tsim los rau cov ntawv thov uas yuav tsum tau muaj kev cuam tshuam, kev ua haujlwm kub tsis zoo, thiab muaj txiaj ntsig zoo.
Qib ib txwm yog PP 401R.
Cov khoom siv tuaj yeem siv rau tsheb bumpers, fenders, hlau clips, hluav taws xob vaj tse, thiab lwm yam khoom siv tsheb. Nws yog tshwj xeeb tshaj yog haum rau cov loj loj, complex, los yog toughness -oriented molded khoom.
Cov yam ntxwv ua haujlwm ntawm PP tuaj yeem pab txhawb kev txhaws ntawm tav, snap- haum qauv, nkhaus nto, thiab nyias - phab ntsa. Rau cov tsheb loj loj, qhov sib xyaw ua ke ntawm cov tawv thiab molding adaptability tuaj yeem yog qhov tseem ceeb ntawm kev yuav khoom.
PP 401R Cov Ntaub Ntawv Kev Ua Haujlwm
PP 401R muaj qhov ntom ntom ntawm 0.95 g / cm³ thiab molding shrinkage ntau ntawm 1.10% -1.40%.
Tensile lub zog thaum so yog 27 MPa, thaum elongation ntawm so mus txog 200%. Qhov siab elongation qhia txog cov khoom muaj peev xwm ua rau muaj ntau yam deformation ua ntej tawg.
Flexural zog yog 35 MPa, nrog flexural modulus ntawm 1250 MPa. Notched Izod cuam tshuam lub zog yog 26 kJ / m².
Nyob rau hauv ib tug load ntawm 0.45 MPa, lub tshav kub deflection kub yog 85 degree.
Cov cuab yeej no ua ke muab polyolefin compound muaj peev xwm deformation muaj peev xwm thiab cuam tshuam kev ua haujlwm rau qhov chaw uas muaj zog thiab qis - tus cwj pwm kub yog qhov tseem ceeb. Nyob rau tib lub sijhawm, cov molding shrinkage ntau dua yuav tsum tau ua tib zoo txiav txim siab thaum tswj qhov loj - qhov ntev.
Sib piv cov khoom rau qhov loj me thiab Geometry
Automotive bumpers thiab fenders ib txwm muaj thaj chaw loj, nkhaus geometry, thiab muaj kev pheej hmoo ntawm kev cuam tshuam sab nraud. Yog li xaiv cov khoom siv yuav tsum txiav txim siab txog kev ua tau zoo, qis - qhov kub thiab txias, yaj ntws, thiab kev tswj qhov ntev ua ke.
Hlau clips yog me me tab sis muab qhov sib txawv xav tau ntawm cov khoom siv. Lawv cov snaps - haum cov qauv xav tau txaus toughness thiab dabtsi yog khoov muaj peev xwm thaum seem tsim nyog rau batch molding npaum.
Rau cov tsev nyob hauv hluav taws xob, cov neeg yuav khoom yuav tsum ntsuas qhov ntsuas kub ua haujlwm thiab cov khoom siv hluav taws xob ua ntej lees paub cov khoom tsim nyog.
Thaum nug, cov neeg siv khoom tuaj yeem muab qhov hnyav, phab ntsa thickness, rooj vag qauv, qhov kub thiab txias ua haujlwm tsawg kawg nkaus, thiab txoj kev sib dhos. Cov ntsiab lus no pab txiav txim seb cov khoom puas phim cov pwm uas twb muaj lawm thiab ua tiav -ib feem yuav tsum tau ua.
Kev them nyiaj yug rau kev hloov kho PP
Diyou Cov Khoom Tshiab muaj kev tshawb fawb, kev hloov kho extrusion, thiab kev txhaj tshuaj molding pov thawj muaj peev xwm hloov kho PP pellets.
Cov lus pom zoo ntawm cov khoom thiab cov txheej txheem tuaj yeem ua raws li tus cwj pwm xav tau, cuam tshuam kev ua haujlwm, thiab molding shrinkage.
Lub hauv paus tsim muaj xws li ntxaib- ntsia hlau extrusion thiab txhaj tshuaj molding txheej txheem, tso cai rau cov ntaub ntawv los soj ntsuam los ntawm qhov tseeb molded qhov chaw los yog cov qauv kuaj.
Rau cov khoom siv tsheb loj thiab cov haujlwm ua haujlwm tas mus li, cov khoom siv raw, kev ua haujlwm, thiab cov khoom tiav tuaj yeem tswj hwm los ntawm cov txheej txheem zoo.
Kev txhawb nqa rau polyolefin compound kuj tseem tuaj yeem suav nrog kev tsom xam ntawm qhov shrinkage, tsis tiav filling, warpage, thiab demolding teeb meem pom thaum txhaj tshuaj ntau lawm.
