Qhov sib txawv tseem ceeb ntawm LLDPE thiab metallocene LLDPE yog tias LLDPE muaj qhov cuam tshuam qis thiab puncture kuj piv rau metallocene LLDPE.
LLDPE yog cov kab uas tsis tshua muaj polyethylene. Nws txawv ntawm LDPE (tsawg-density polyethylene) structurally vim LLDPE tsis muaj saw ntev ntev. Lub linearity ntawm LLDPE tshwm sim vim nws txoj kev tsim khoom sib txawv. Metallocene LLDPE yog derivative ntawm LLDPE.
LLDPE yog dab tsi
LLDPE yog cov kab uas tsis tshua muaj polyethylene. Nws yog ib tug linear polymer nrog luv-chain branching, thiab peb tsim nws ntawm copolymerization ntawm ethylene nrog olefins muaj chains ntev. Peb yuav tsum siv qhov kub thiab txias qis thaum lub sijhawm tsim khoom no. Cov khoom kawg ntawm cov txheej txheem no muab qhov nqaim molecular hnyav faib. Tsis tas li ntawd, cov catalyst peb siv rau cov txheej txheem tsim khoom no yog Ziegler catalyst.
Daim duab 01: Granules ntawm LLDPE
Lub polymerization tuaj yeem ua tiav hauv theem kev daws teeb meem lossis theem roj. Tsis tas li ntawd, thaum xav txog nws cov khoom, LLDPE muaj lub zog tensile siab, muaj kev cuam tshuam siab thiab puncture tsis kam thaum piv rau LDPE. Ntxiv mus, cov khoom no yog hloov tau yooj yim heev. Nws tuaj yeem ncua kev ntxhov siab.
Metallocene LLDPE yog dab tsi
Metallocene LLDPE yog daim ntawv ntawm cov kab hluav taws xob tsawg-density polyethylene peb tsim siv cov metallocene catalyst. Peb qhia nws li mLLDPE. Cov khoom no muaj kev cuam tshuam zoo heev thiab puncture kuj.
Daim duab 02: mLLDPE tseem ceeb hauv daim ntawv thov ntim tshuaj
Tsis tas li ntawd, nws muab cov txiaj ntsig zoo rau cov cua sov. Cov khoom tseem ceeb ntawm metallocene LLDPE ua rau nws haum rau hauv cov ntawv thov kev ua haujlwm siab hauv cov zaub mov thiab tshuaj.
Qhov txawv ntawm LLDPE thiab Metallocene LLDPE
LLDPE yog linear low-density polyethylene thaum Metallocene LLDPE yog daim ntawv ntawm linear low-density polyethylene peb tsim siv cov metallocene catalyst. Qhov sib txawv tseem ceeb ntawm LLDPE thiab metallocene LLDPE yog tias LLDPE muaj qhov cuam tshuam tsawg thiab puncture kuj piv rau metallocene LLDPE.
Ntxiv mus, LLDPE muaj txiaj ntsig zoo hauv kev tsim cov hnab yas, cov ntawv, hnab yas, hnab, cov khoom ua si, npog, thiab lwm yam thaum Metallocene LLDPE muaj txiaj ntsig zoo hauv kev ua yeeb yaj kiab zoo xws li cov khoom noj thiab ntim tshuaj, hnyav- lub luag hauj lwm sacks, ua liaj ua teb zaj duab xis thiab lwm yam uas tsis yog-packing daim ntaub ntawv xws li rwb thaiv tsev.
Hauv qab infographic muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm LLDPE thiab metallocene LLDPE.
Summary – LLDPE vs Metallocene LLDPE
LLDPE yog linear low-density polyethylene thaum metallocene LLDPE yog daim ntawv ntawm linear low-density polyethylene uas peb tsim siv cov metallocene catalyst. Qhov sib txawv tseem ceeb ntawm LLDPE thiab metallocene LLDPE yog tias LLDPE muaj qhov cuam tshuam tsis zoo thiab puncture tsis kam piv rau metallocene LLDPE.
