"Metallocene" yog hais txog cov organic hlau kev ua liaj ua teb tsim los ntawm kev hloov pauv hlau (xws li zirconium, titnium, tshuaj phev, thiab lwm yam) thiab cyclopentadiene. Polypropylene synthesized nrog melococene catalysts yog hu ua Metallocene Polypropylene (MPP).
MetalloCene polypropylene (MPP) muaj cov dej ntws ntau dua, cov tshuaj tsw qab, ua yeeb yaj kiab qis, kev kho mob, kho mob, thiab lwm tus. Kev tsim cov metallocene polypropylene (MPP) cuam tshuam ntau cov kauj ruam tseem ceeb, suav nrog kev npaj catalyst, polymerization, thiab ua tom ntej.
1. Kev Npaj Catalianst:
Kev xaiv ntawm Metallocene catalyst: Qhov kev xaiv ntawm Metalocene catalyst yog qhov tseem ceeb hauv kev txiav txim siab cov khoom ntawm lub txiaj ntsig ntawm lub txiaj ntsig ntawm lub txiaj ntsig ntawm lub txiaj ntsig Cov catalysts feem ntau muaj kev hloov pauv ntawm cov kev hloov pauv, xws li zirconium lossis titanium, sandwiched ntawm cyclopentadienyl nigands.
Cocatallyst Ntxiv: Mackalrocene catalysts feem ntau yog siv nyob rau hauv kev sib txuas nrog co coxatalyst, feem ntau yog aluminium raws li compound. Lub Cocatallyst ua kom lub tshuab MOALALLOCEL CATALYST, tso cai rau nws los pib ua cov tshuaj tiv thaiv polymerization.
2. Polymerization:
Kev Pub Khoom Noj: Propylene, cov monomer rau polyper rau polypropylene, feem ntau yog siv los ua thawj pub. Cov kab mob ua kom huv yog ntxuav kom tshem tawm impurities uas tuaj yeem cuam tshuam nrog cov txheej txheem polymerization.
Reactor Teeb: Cov tshuaj tiv thaiv polymerization tau siv nyob rau hauv cov tshuaj reactor nyob rau hauv cov kev pab tswj kom zoo. Reactor teeb tsa suav nrog Metallocene catalyst, Cocataltys, thiab lwm yam ntxiv uas yuav tsum muaj rau cov khoom siv polymer.
Polymerization tej yam mob: Cov kev tshwm sim ntawm cov tshuaj tiv thaiv, xws li kub, thiab chaw nyob ua tib zoo tswj hwm kom ntseeg tau tias qhov xav tau cov qauv molecular thiab polymer. Metallocene catalysts pab txhawb ntau txoj kev tswj hwm cov kev tswj hwm cov no piv rau cov ntoo tsoosalysts.
3. Copolymerization (yeem):
Kev sib txuam ntawm cov co-monomers: qee kis, MPP yuav yog copolymerized nrog lwm cov monomers los hloov kho nws cov khoom. Cov co-monomers suav nrog ethylene lossis lwm yam alpha-olefins. Kev sib txuam ntawm cov co-monomers tso cai rau kev customization ntawm cov polymer rau cov ntawv thov tshwj xeeb.
4. Kev txiav tawm thiab quenching:
Cov tshuaj tiv thaiv kev txiav tawm: Thaum cov polymerization ua tiav, cov tshuaj tiv thaiv tau xaus. Qhov no feem ntau tau ua tiav los ntawm kev qhia cov neeg sawv cev txiav uas cuam tshuam nrog cov kev nquag ua haujlwm polymer polymer pawm sab laug.
Quenching: Lub polymer yog li sai tau txias lossis quenched los tiv thaiv cov tshuaj tiv thaiv ntxiv thiab kom muaj txiaj ntsig cov polymer.
5. Polymer rov qab thiab ua tiav:
Polymer sib cais: lub polymer yog sib cais los ntawm cov tshuaj tiv thaiv sib xyaw. Kev tsis raug cai Monomers, catalyst cov seem, thiab lwm yam khoom noj yog muab tshem tawm los ntawm ntau hom kev sib cais.
Cov kauj ruam tom qab: Cov MPP yuav ua rau cov kauj ruam ntxiv, xws li extrusion, compound, thiab pelletization, kom ua tiav cov khoom xav tau thiab cov khoom. Cov kauj ruam no tseem tso cai rau kev sib koom tes ntawm cov quav ntxiv xws li cov neeg sawv cev, cov antioxidants, stabilizers, cov xim, thiab lwm yam kev sib ntxiv.
Ua kom zoo MPP: qhov sib sib zog nqus dej mus rau hauv tus cwj pwm tseem ceeb ntawm kev ua cov khoom ntxiv
NKAUS TUAJ YEEM: Cov nplais sawv, xws li ntev-cov rog rog rog, feem ntau ntxiv rau kev sib txhuam ntawm polymer chains, tiv thaiv kev ua tiav thaum ua. Qhov no pab txhim kho qhov extrusion thiab moulding txheej txheem.
Ntws txhim kho:Ntws ua kom zoo los yog ua pab AIDS, zoo li polyethylene waxes, yog siv los txhim kho cov suab hlub ntws ntawm MPP. Cov tshuaj ntxiv no txo cov viscosity thiab txhim kho cov polymer lub peev xwm los sau cov khoom lag luam yooj yim, ua rau muaj cov txheej txheem zoo dua.
Antioxidants:
Stabilizers: antioxidant yog cov quav ntxiv uas tiv thaiv MPP los ntawm kev ua tsis raws cai. Hindered phenols thiab phosphites feem ntau siv cov stabilizers uas inhibit tsim kev tsim cov dawb radicals, tiv thaiv cov thermal thiab oxidative degradation.
Nucileating tus sawv cev:
Nucileating tus sawv cev, xws li TALC lossis lwm cov inorganic incounds, tau ntxiv los txhawb qhov tsim ntawm cov qauv crystalline ntau hauv MPP. Cov tshuaj ntxiv no txhim kho lub polymer cov cuab yeej siv cov neeg kho tshuab, suav nrog cov tawv ncauj thiab cuam tshuam tsis kam.
Colorants:
Pigments thiab dyes: Colorants feem ntau koom rau MPP kom ua tiav cov xim tshwj xeeb hauv cov khoom kawg. Pigments thiab dyes raug xaiv raws li cov xim xav tau thiab cov ntawv thov yuav tsum tau ua.
Kev Hloov Kho Hloov Kho:
Elastomers: Hauv cov ntawv thov uas cuam tshuam tsis kam yog qhov tseem ceeb, kev hloov kho roj hmab uas muaj kuab dawb paug xws li roj hmab uas muaj kuab roj ntxiv rau MPP. Cov kev hloov kho tshiab txhim kho kev nruj ntawm cov polymer yam tsis muaj lwm yam tshuaj tiv thaiv lwm yam.
Compatibilizers:
Txiv neej monshydride grafts: compatibilizers yuav siv tau los txhim kho kev sib txuam ntawm MPP thiab lwm yam polymers lossis ntxiv. Txiv neej moov anhydride graftts, piv txwv li, tuaj yeem txhim kho cov nplaum ntawm cov khoom sib txawv polymer.
Npleem thiab AntiBrolock tus neeg sawv cev:
Npleem muag: Ntxiv rau kev txo kev sib txhuam, cov nplais sawv tuaj yeem ua tau raws li cov neeg sawv cev los tiv thaiv cov neeg sawv cev. AntiBlock tus sawv daws tiv thaiv cov ua ke ntawm zaj duab xis lossis cov ntawv thaum lub sijhawm cia.
(Nws yog ib qho tseem ceeb kom nco ntsoov tias cov kev ua kom muaj kev ntxiv hauv MPP tsim cov khoom lag luam zoo li cov khoom lag luam. Kev siv ntawm Metalrodocene catalysts hauv Kev tsim cov MPP muab ib theem ntxiv ntawm kev tswj hwm thiab precision, tso cai rau kev sib txuam ntawm cov quav ntxiv rau hauv txoj kev uas tuaj yeem ua kom tau raws li cov cai.)
