Yuav Ua Li Cas Paub LLDPE Los Ntawm LDPE?

LDPE yog non-toxic, tasteless, tsw, thiab muaj qhov ntom ntawm 0 910-0.940g/cm3. Nws yog polymerized nrog oxygen los yog organic peroxide raws li ib tug catalyst nyob rau hauv lub siab ntawm 100 ~ 300MPa, los yog hu ua high-pressure polyethylene.

LLDPEyog non-toxic, tasteless, tsw, nrog ib tug ceev ntawm 0 915-0.935g/cm3. Nws yog ib tug copolymer ntawm ethylene thiab ib tug me me ntawm advanced alpha-olefin (xws li butene-1, hexene-1, octene -1, tetrmethylpentene -1, thiab lwm yam) polymerized nyob rau hauv siab los yog tsis tshua muaj siab nyob rau hauv qhov kev txiav txim ntawm ib tug catalyst. Cov qauv molecular ntawm cov pa LLDPE yog tus cwj pwm los ntawm nws cov kab rov tav kab rov tav, nrog ob peb los yog tsis muaj cov saw ntev ntev, tab sis muaj qee cov saw luv luv. Qhov tsis muaj cov saw ntev ntev ua rau cov polymer ntau crystalline.

• Kev sib piv ntawm LLDPE thiab LDPE

1. Melt flow yam ntxwv

Cov yam ntxwv yaj ntawm LLDPE tau yoog raws li cov txheej txheem tshiab, tshwj xeeb tshaj yog cov txheej txheem nyias nyias, los tsim cov khoom zoo. LLDPE yog siv nyob rau hauv tag nrho cov tsoos kev lag luam ntawm polyethylene, thiab nws tsis kam mus stretch, nkag mus, cuam tshuam thiab tsim kua muag ua rau LLDPE ntau haum rau nyias films. Nws zoo heev tsis kam mus rau ib puag ncig kev nyuaj siab tawg, tsis tshua muaj kub thiab warping ua rau LLDPE haum rau tubing, ntawv extrusion thiab tag nrho cov molding daim ntaub ntawv.

2.LLDPE thiab LDPE siv

LLDPE tsim cov qauv crystalline ntau dua vim tias tsis muaj cov saw ntev ntev. Qhov loj dua crystallinity ntawm LLDPE ua ib yam khoom uas muaj zog dua. Qhov siab dua crystallinity no kuj ua rau lub melting point ntawm LLDPE los ntawm 10 ~ 15 degree piv nrog LDPE. Lub zog tensile siab dua, tiv thaiv kev nkag mus, tsim kua muag thiab nce elongation yog cov yam ntxwv ntawm LLDPE, ua rau nws tshwj xeeb tshaj yog haum rau cov yeeb yaj kiab nyias.

LDPE muaj zoo softness, extensibility, transparency, txias kuj thiab processability. Nws cov tshuaj ruaj khov zoo, tuaj yeem tiv taus acid, alkali thiab ntsev aqueous tov; Zoo hluav taws xob rwb thaiv tsev thiab roj permeability; Kev nqus dej tsawg; Yooj yim rau hlawv. Cov cuab yeej yog mos, nrog zoo extensibility, hluav taws xob rwb thaiv tsev, tshuaj stability, kev ua tau zoo thiab kub tsis kam (ua hauj mus rau -70 degree ).

3. Txheej txheem

LDPE: Nrog kev ua haujlwm zoo, tsim nyog rau ntau yam txheej txheem yas, suav nrog kev txhaj tshuaj molding, extrusion, tshuab moulding, thiab lwm yam.
LLDPE: Kev ua haujlwm kub yog me ntsis siab dua LDPE, tab sis vim nws cov qauv linear, lub melting txaus yog zoo, haum rau tshuab molding, extrusion molding, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov zaj duab xis thiab yeeb nkab muaj ntau yam zoo.

• Txoj kev sib txawv

LDPE:Kev paub txog kev xav: muag muag; Dawb pob tshab, tab sis lub pob tshab yog qhov nruab nrab;

combustion identification: hlawv nplaim daj thiab xiav; Thaum hlawv tsis muaj pa taws, muaj cov ntxhiab tsw paraffin, yaj dripping, yooj yim los kos hlau.

Siv dav hauv kev tsim cov hnab yas hauv lub neej txhua hnub, ntim khoom noj, shrink film, extrusion txheej thiab lwm yam.

LLDPE: LLDPE tuaj yeem swell nyob rau hauv kev sib cuag nrog benzene rau lub sij hawm ntev, thiab ua nkig nyob rau hauv kev sib cuag nrog HCL rau lub sij hawm ntev.

Haum rau cov khoom uas xav tau lub zog tensile siab dua thiab tsim kua muag, xws li cov khoom ntim zaj duab xis, ua liaj ua teb zaj duab xis, stretch qhwv zaj duab xis, hauv ob sab phlu, yeeb nkab, cable tsho, thiab lwm yam.

Hauv cov ntsiab lus, LLDPE thiab LDPE ua lub luag haujlwm tseem ceeb hauv ntau hom kev tiv thaiv cov dej ntws. HDPE, LDPE thiab LLDPE peb hom ntaub ntawv muaj cov rwb thaiv tsev zoo thiab noo noo-pov thawj, impermeability, non-toxic, tasteless, odorless kev ua tau zoo ua rau nws nyob rau hauv kev ua liaj ua teb, aquaculture, dag lub pas dej, reservoirs, dej daim ntaub ntawv kuj yog heev nthuav.
