Recycling Technology ntawm Polypropylene Txhaj Moulded Parts

Polypropylene (PP) yog tam sim no thib ob loj tshaj plaws-lub hom phiaj yas. Nrog rau txoj kev loj hlob ntawm kev lag luam xws li kev tsim kho, tsheb, khoom siv hauv tsev thiab ntim khoom, khib nyiab PP tau dhau los ua ib qho ntawm cov khoom siv khib nyiab loj tshaj plaws hauv xyoo tas los. Tam sim no, txoj hauv kev tseem ceeb los daws cov khib nyiab PP yog: incineration rau cov khoom siv hluav taws xob, catalytic cracking los npaj roj, siv ncaj qha thiab rov ua dua tshiab. Xav txog tej yam xws li kev ua tau zoo, tus nqi, kev siv hluav taws xob thiab kev tiv thaiv ib puag ncig hauv cov txheej txheem ntawm kev ua cov khib nyiab PP, kev rov ua dua tshiab yog qhov feem ntau siv, muaj txiaj ntsig thiab kev tawm tswv yim tshaj plaws los daws cov khib nyiab PP.

Vim muaj kev cuam tshuam ntawm cov yam ntxwv xws li lub teeb, cua sov, oxygen thiab sab nraud quab yuam thaum siv, cov qauv molecular ntawm PP yuav hloov, thiab cov khoom yuav daj, nkig, los yog tawg, ua rau PP toughness, seem stability, thermo- oxidative stability thiab workability. Nws yog qhov pom tseeb dua, thiab nws nyuaj rau ncaj qha siv cov khib nyiab PP los tsim cov khoom kom tau raws li qhov yuav tsum tau ua thiab siv. Yog li ntawd, kev siv thev naus laus zis ntawm cov pov tseg PP txuas ntxiv txhim kho. Alloying nrog lwm cov polymers los yog compounding nrog fillers tuaj yeem txhim kho kev ua tau zoo, thermal zog, lub cev thiab txhua yam khoom ntawm khib nyiab PP, thiab paub txog kev ua haujlwm siab ntawm cov khib nyiab PP.

• Alloying

Alloying yog txheej txheem ntawm kev sib xyaw cov khib nyiab PP nrog rau lwm cov ntaub ntawv polymer los npaj cov ntaub ntawv macroscopically homogeneous. Los ntawm kev xaiv cov ntaub ntawv sib txawv polymer rau alloying, cov khoom ua haujlwm, lub cev thiab lub zog ntawm cov khoom pov tseg PP tuaj yeem txhim kho. Piv txwv li, kev siv elastomers tuaj yeem txhim kho qhov cuam tshuam ntawm cov khoom pov tseg PP.

Muaj kev tshawb fawb txog cov khoom siv kho tshuab thiab thermal deformation tus cwj pwm ntawm cov khib nyiab PP / RU cov roj hmab sib xyaw (natural roj hmab thiab styrene-butadiene roj hmab txhua tus account rau 50 feem pua). Cov theem txuas ntxiv ntawm cov khib nyiab PP tuaj yeem txhim kho qhov cuam tshuam lub zog thiab elongation ntawm kev tawg ntawm cov khib nyiab PP, tab sis nws yuav txo qhov rigidity thiab thermal deformation tsis kam ntawm PP.

Vim tias feem ntau cov elastomers tsis sib haum nrog cov khib nyiab PP, qhov sib txuas sib txuas tsis zoo, thiab muaj kev sib cais theem thaum ua thiab siv, uas cuam tshuam rau nws cov kev ua tau zoo. Txhawm rau txhim kho kev sib raug zoo ntawm kev sib raug zoo ntawm cov khib nyiab PP alloys thiab txhim kho cov kev sib txuas ntawm lub ntsej muag, ntau tus kws tshawb fawb tau ua tiav kev tshawb fawb thiab pom ob yam khoom uas tuaj yeem txhim kho qhov sib txuam ntawm cov ntaub ntawv sib xyaw thiab txhim kho cov khoom ntim khoom, poob modulus thiab qhov system. viscosity ntawm cov khoom sib xyaw. compatibilizer.

Tus neeg sawv cev vulcanizing tuaj yeem txhim kho qhov cuam tshuam thiab tensile lub zog, yaj viscosity, elongation ntawm tawg thiab ductility ntawm cov khoom sib xyaw; qhov sib ntxiv ntawm peroxide crosslinking tus neeg sawv cev tuaj yeem txhim kho qhov sib xyaw ntawm cov khoom sib xyaw thiab txhim kho cov khoom sib xyaw. cuam ​​tshuam thiab tensile lub zog, tab sis ua rau me ntsis txo qis hauv elongation thaum so.

• Kev sib xyaw ua ke

Kev sib xyaw ua ke yog cov txheej txheem ntawm kev sib xyaw cov khoom pov tseg PP thiab cov ntaub ntawv tsis-polymer los npaj cov ntaub ntawv sib xyaw, thiab nws yog txoj hauv kev tseem ceeb kom ua tiav kev ua haujlwm siab thiab ua haujlwm ntawm cov khib nyiab PP. Composite pov tseg PP tuaj yeem txhim kho nws cov rigidity, lub zog, thermal, hluav taws xob thiab lwm yam khoom siv lub cev thiab tshuab, thiab txo cov nqi. Raws li cov muab tub lim muaj pes tsawg leeg, nws tuaj yeem muab faib ua inorganic fillers thiab organic fillers.

• Kev sib xyaw ntawm inorganic fillers

Inorganic fillers feem ntau siv hauv PP compounding tuaj yeem siv los ua cov khib nyiab PP, xws li calcium carbonate, talc, montmorillonite, hlau oxides, ya tshauv thiab iav fibers. Txoj kev tshawb nrhiav pom tias txawm hais tias cov khoom siv tsis zoo no tuaj yeem txhim kho qhov rigidity ntawm pov tseg PP thiab txo tus nqi, tab sis qhov polarity ntawm khib nyiab PP yog qhov sib txawv heev, lub zog saum npoo yog siab, thiab kev sib raug zoo yog qhov tsis zoo, uas ua rau txo qis elongation. Thaum tawg thiab cuam tshuam toughness ntawm cov khoom sib xyaw.

• Kev sib xyaw ntawm cov organic fillers

Feem ntau cov organic fillers muaj xws li ntoo hmoov thiab ntoo fiber ntau, hmoov txhuv nplej siab, nplej straw, hemp fiber thiab pov tseg ntawv xov xwm. Muaj kev tshawb fawb ntawm microcellular foaming tshuab ntawm ntoo fiber ntau filling khib nyiab PP. Cov txiaj ntsig tau pom tias thaum lub melting kub yog 180 ° C thiab tuav lub siab yog 12.5 MPa, lub microcellular qauv yog uniformly faib. Cov qauv microporous tuaj yeem txuas ntxiv txoj hauv kev nthuav tawm ntawm cov kab nrib pleb thiab nqus sab nraud cuam tshuam lub zog, yog li txhim kho kev cuam tshuam lub zog.

Ntuj fiber ntau yog cov khoom siv pov tseg PP. Raws li qhov pom ntawm nws cov dej nqus dej siab thiab tsis sib haum nrog cov khib nyiab PP, kev kho saum npoo yog txoj hauv kev tseem ceeb kom ua tiav cov txiaj ntsig zoo ntawm cov khoom siv fiber ntau hauv PP composites. Tsis tas li ntawd, pov tseg polyester kuj tuaj yeem siv los hloov cov khib nyiab PP. Qee cov kws tshawb fawb tau kawm txog tus cwj pwm crystallization ntawm -nucleated pov tseg PP / pov tseg polyester ntaub sib xyaw. Cov txiaj ntsig tau pom tias pov tseg polyester thiab -nucleating tus neeg saib xyuas muaj cov theem sib txawv ntawm cov khib nyiab PP crystallization. Nucleation tsub kom lub crystallization kub ntawm pov tseg PP thiab induces tsim muaju.

• Hybrid compounding

Hybrid compounding yog ib txoj kev uas ob los yog ntau tshaj cov khoom siv polymers tau siv los npaj cov khoom sib xyaw. Vim muaj kev txwv ntawm ib qho muab tub lim, hybrid compounding tuaj yeem txhim kho cov khoom zoo ntawm cov polymers los ntawm kev sib xyaw ua ke thiab kev sib koom ua ke ntawm cov khoom sib txawv. Yog li ntawd, kev tshawb fawb txog kev npaj thiab cov khoom muaj feem xyuam ntawm cov khoom pov tseg PP cov khoom sib xyaw uas muaj cov khoom sib xyaw ua ke tau nyiam, thiab cov muab tub lim koom nrog feem ntau suav nrog cov khoom sib xyaw inorganic thiab inorganic / organic fillers.

• Alloy compounding

Txhawm rau muab kev ua si tag nrho rau qhov zoo ntawm alloying thiab compounding, qee cov kws tshawb fawb tau pib ua cov alloying thiab compounding los txhim kho ntxiv thiab txhim kho lub cev thiab cov khoom siv ntawm cov khib nyiab PP, thiab paub txog kev ua haujlwm siab thiab kev lag luam ntawm cov khib nyiab PP, xws li cov organic. fillers thiab elastomers, inorganic cov ntaub ntawv. Fillers thiab elastomers yog ua ke nrog hloov cov khib nyiab PP, thiab lwm yam.

Cov kev tshawb fawb tau tshwm sim hauv qhov no qhia tau hais tias cov pob txha ntawm cov khib nyiab PP thiab talc-filled PP composites yog ob qho tib si kev coj cwj pwm ntawm qhov kub thiab txias, thiab qhov sib ntxiv ntawm EOC (ethylene-octene copolymer) tuaj yeem txhim kho qhov cuam tshuam ntawm cov khoom sib xyaw; EOC nce Tus cwj pwm zoo ntawm cov khoom siv hluav taws xob ntawm cov khoom siv talc-filled PP composites tsis hloov nrog qhov nce ntawm cov sij hawm rov ua dua.
