Metallocene polyethylene (mPE) yog ib hom polyethylene resin synthesized raws li metallocene catalysts, uas yog ib qho tseem ceeb heev hauv kev lag luam polyolefin hauv xyoo tas los no. Cov hom khoom feem ntau suav nrog metallocene low density high pressure polyethylene, metallocene high density low pressure polyethylene thiab metallocene linear low density polyethylene. Metallocene polyethylene tau siv dav hauv ntau txheej co-extrusion tshuab molding txheej txheem vim nws cov khoom tshwj xeeb thiab kev ua haujlwm, thiab tau txais kev nyiam los ntawm cov tuam txhab ntim khoom hauv tsev thiab txawv teb chaws.
Cov khoom ntawm metallocene polyethylene
1. Metallocene polyethylene muaj qhov ntev zoo dua thaum tawg dua li cov polyethylene ib txwm muaj. Metallocene polyethylene muaj lub zog cuam tshuam zoo dua vim nws qhov hnyav molecular siab dua thiab kev faib tawm ntom dua li cov polyethylene ib txwm muaj.
2. Qhov kub ntawm qhov kub thiab txias dua thiab lub zog ntawm qhov kub thiab txias dua.
3. Zoo dua pob tshab thiab qis dua tus nqi haze.
Cov ntawv thov zaj duab xis metallocene polyethylene
1. Cov khoom noj khoom haus ntim khoom
Cov yeeb yaj kiab metallocene polyethylene tuaj yeem laminated nrog BOPET, BOPP, BOPA thiab lwm yam yeeb yaj kiab, tshwj xeeb tshaj yog haum rau ntim cov khoom noj nqaij, khoom noj yooj yim, khoom noj khov thiab lwm yam khoom.
2. Kev ntim khoom ua liaj ua teb
Cov yeeb yaj kiab metallocene polyethylene uas tau tshuab ua los ntawm ntau yam txheej txheem sib txawv rau kev thaiv dej pa zoo, thaum cov pa oxygen permeability siab, qhov no ua rau nws tshwj xeeb tshaj yog rau cov txiv hmab txiv ntoo tshiab thiab zaub ntim. Tsis tas li ntawd, cov yeeb yaj kiab metallocene polyethylene uas tau tshuab muaj cov yam ntxwv ntawm lub zog siab, tiv thaiv kev pos huab, tiv thaiv kev ntws, tiv thaiv kev laus thiab pob tshab zoo.
3. Cov hnab hnyav
Cov hnab hnyav feem ntau yog siv rau kev ntim cov khoom siv yas, chiv, pub tsiaj, mov thiab cov nplej. Vim muaj cov metallocene polyethylene, cov hnab hnyav no ua rau nws muaj kev ua haujlwm sealing, tiv taus dej noo, tiv taus dej, tiv taus kev laus zoo dua, thiab tsis yooj yim tawg thaum kub siab.
Qhov ntxiv ntawm metallocenes hauv kev ua zaj duab xis txhim kho lub zog tensile thiab qhov zoo ntawm zaj duab xis, tab sis kuj muaj qee qhov kev cov nyom hauv kev ua, xws li qhov viscosity siab ntawm metallocenes cuam tshuam rau kev ua kua thiab qhov tshwm sim ntawm kev tawg ntawm cov khoom hauv cov txheej txheem extrusion.
Cov laj thawj rau kev tawg ntawm metallocene polyethylene hauv kev ua cov yeeb yaj kiab yuav suav nrog cov hauv qab no:
1. siab viscosity: metallocene polyethylene muaj viscosity siab yaj, uas tuaj yeem ua rau yaj tawg thaum lub sijhawm extrusion vim tias yaj raug rau lub zog siab shear thaum nws hla dhau lub qhov tuag.
2. Kev tswj kub tsis txausYog tias qhov kub ntawm cov txheej txheem siab dhau lossis tsis sib npaug, qhov no yuav ua rau cov khoom siv yaj dhau hauv qee qhov chaw thaum tseem kho qee qhov hauv lwm qhov, thiab qhov xwm txheej yaj tsis sib npaug no yuav ua rau tawg ntawm qhov chaw yaj.
3. Kev ntxhov siab ntawm kev txiav: Hauv cov txheej txheem extrusion, cov yaj yuav raug kev nyuaj siab ntau dhau ntawm lub muzzle tuag, tshwj xeeb tshaj yog tias lub muzzle tuag tsis tsim kom zoo lossis qhov ceev ua tiav sai dhau, qhov kev ntxhov siab siab no yuav ua rau yaj tawg.
4. Cov khoom ntxiv los yog cov masterbatchesCov khoom ntxiv lossis cov masterbatches ntxiv thaum lub sijhawm ua cov khoom uas tsis sib npaug kuj tseem yuav cuam tshuam rau cov yam ntxwv ntawm cov dej ntws ntawm cov yaj, ua rau cov yaj tawg.
SILIKE PFAS-dawb PPA SILIMER 9300, Txhim kho metallocene polyethylene yaj tawg
Cov khoom SILIMER series yog cov khoom siv polymer ua cov khoom siv (PPA) uas tsis muaj PFAS.uas tau tshawb fawb thiab tsim los ntawm Chengdu Silike. Cov khoom no yog Pure modified Copolysiloxane, nrog cov khoom ntawm polysiloxane thiab cov nyhuv polar ntawm pawg hloov kho.
SILIMER-9300yog ib qho silicone additive uas muaj cov pab pawg polar functional, siv rau hauv PE, PP thiab lwm yam yas thiab roj hmab cov khoom, tuaj yeem txhim kho kev ua thiab tso tawm, txo cov pwm tsim thiab txhim kho cov teeb meem tawg, yog li cov khoom txo qis zoo dua.
Tib lub sijhawm ntawd,SILIMER 9300Nws muaj cov qauv tshwj xeeb, sib haum zoo nrog cov matrix resin, tsis muaj nag lossis daus, tsis muaj kev cuam tshuam rau qhov tsos ntawm cov khoom thiab kev kho qhov chaw. Nws raug pom zoo kom dilute rau hauv qee cov ntsiab lus masterbatch ua ntej, tom qab ntawd siv rau hauv polyolefin polymers, ntxiv nws hauv qhov nruab nrab tuaj yeem ua tau zoo heev.
NtxivSILIMER 9300rau cov txheej txheem, qhov dej ntws, kev ua haujlwm, thiab lubricity ntawm cov resin tuaj yeem txhim kho tau zoo nrog rau tshem tawm cov pob tawg yaj, kev tiv thaiv hnav ntau dua, cov coefficient sib txhuam me dua, txuas ntxiv cov khoom siv ntxuav lub voj voog, luv lub sijhawm downtime, thiab cov zis siab dua thiab cov khoom zoo dua, qhov kev xaiv zoo meej los hloov cov tshuaj fluorine-based PPA.
