    CHEMICAL PROPERTIES

    Cov khoom siv tshuaj lom neeg thiab lub cev muaj txiaj ntsig tau cuam tshuam los ntawm kev ua kom ceev, uas cuam tshuam los ntawm cov duab thiab qhov sib txawv ntawm cov saw hlau molecular.Cov ntaub ntawv tsawg-density muaj cov ceg ntoo thiab dav dav dav, hos cov khoom siv high-density muaj kev sib piv ncaj thiab zoo sib xws chains.Tsawg-density polyethylene (0.926-0.9409 g / cm3) yog soluble hauv cov kuab tshuaj organic ntawm qhov kub siab tshaj 200 ° F.Nws yog insoluble nyob rau hauv chav tsev kub.High-density polyethylene (0.041-0.965 g / cm3) yog hydrophobic, permeable rau roj, thiab muaj hluav taws xob tiv taus.
    Tsawg molecular hnyav polyethylene muaj cov hluav taws xob zoo heev thiab ua rau dej thiab tshuaj lom neeg feem ntau.Nruab nrab molecular hnyav polymers yog waxes miscible nrog paraffin wax, thiab polyethylene polymers uas nws cov luj molecular siab tshaj 10,000 yog cov paub tawv thiab muaj zog resins uas hloov tau los yog tawv.Los ntawm kev sib txawv ntawm cov catalyst thiab cov txheej txheem ntawm polymerization, cov khoom xws li qhov ntom ntom, crystallinity, molecular hnyav, thiab polydispersity tuaj yeem tswj tau ntau yam.Polymers nrog qhov ntom ntom ntawm kwv yees li 0.910 txog 0.925 g / cm3 yog polyethylene tsawg;cov neeg uas muaj qhov ntom ntom ntawm 0.926 txog 0.940 g / cm3 yog nruab nrab-qhov ntom ntom polyethylene;thiab cov uas muaj qhov ntom ntom ntawm 0.941 txog 0.965 g / cm3 thiab siab dua yog cov polyethylene high-density.

    APPLICATION AREA

    Tshuaj
    Kev lag luam roj
    Tshuaj tua kab
    Diesel Cav Roj
    Cov tub yees
    Aerosol tshuaj tsuag

    Polyethylene (PE) yog ib qho thermoplastic polymer uas muaj cov hlua ntev hydrocarbon.PE yog siv nyob rau hauv ib tug xov tooj ntawm daim ntawv thov nrog rau cov ntaub ntawv yooj yim ntim uas tsim los ntawm cov txheej txheem cua tshuab.Polyethylene yog siv los tswj viscosity, ncua kev kawm ntawv, thiab kev ruaj ntseg nyob rau hauv cov tshuaj pleev ib ce formulations.Cov ntawv thov suav nrog tshwj xeeb txhaj tshuaj molded qhov chaw, hauv cov teb no Polyethylene muaj ntau yam kev siv:
    Txhaj thiab tshuab moulded cov khoom ua si, cov khoom siv hauv tsev thiab lub hau.
    Txhaj tshuaj molded lub rooj zaum tsheb, tshuab txiav thiab pails.
    Txhaj tshuaj molded, nyias-walled ntim thiab housewares.
    Kub yaj txheej rau ntawv, additives nyob rau hauv cam khwb cia moldings, tswm ciab, roj-raws li inks thiab kub yaj adhesives.
    Ntxiv rau unsaturated polyesters, epoxides thiab lwm yam polymers los muab cov khoom tshwj xeeb ntawm UHMWPE.Siv nyob rau hauv industrial qhov chaw, coatings thiab hnav nto ntawm 10-40 wt.%.
    Cov ntawv thov ua yeeb yaj kiab muaj qhov zoo rub tawm thiab toughness.
    Pwm tso additive, lubricant nyob rau hauv cov roj hmab ua, extrusion thiab calendering pab rau PVC thiab dispersing pab rau xim concentrates.
    Bearings, iav, bushings thiab lwm yam txav mus.
    Laboratory tubing;nyob rau hauv ua prostheses;hluav taws xob rwb thaiv tsev;cov khoom ntim;chav ua noj;lub tank thiab cov kav dej;ntawv txheej;textile stiffeners.
    polyethylene yog siv los tswj viscosity, ncua kev kawm ntawv, thiab kev ruaj ntseg nyob rau hauv cov tshuaj pleev ib ce formulations.Nws yog muab los ntawm roj av los yog lub cev qhuav dej ntawm cawv.

    YUAV UA LI CAS LOS NTAWM US

    Chemwin tuaj yeem muab ntau hom hydrocarbons thiab cov kuab tshuaj tshuaj lom neeg rau cov neeg siv khoom.Ua ntej ntawd, thov nyeem cov lus qhia hauv qab no txog kev ua lag luam nrog peb: 

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws.Ntxiv nrog rau kev muab cov neeg siv khoom paub txog kev nyab xeeb thiab ib puag ncig tus phooj ywg siv ntawm peb cov khoom, peb kuj tau cog lus los xyuas kom meej tias qhov kev pheej hmoo ntawm kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis rau qhov tsim nyog thiab ua tau tsawg kawg nkaus.Yog li ntawd, peb xav kom tus neeg siv khoom kom ntseeg tau tias qhov tsim nyog tshem tawm thiab khaws cov qauv kev nyab xeeb tau ua tiav ua ntej peb xa khoom (thov xa mus rau HSSE appendix nyob rau hauv cov nqe lus dav dav thiab kev muag khoom hauv qab no).Peb cov kws tshaj lij HSSE tuaj yeem muab kev taw qhia txog cov qauv no.

    2. Txoj kev xa khoom

    Cov neeg siv khoom tuaj yeem xaj thiab xa khoom los ntawm chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov chaw tsim khoom.Cov hom kev thauj mus los muaj xws li tsheb thauj mus los, tsheb ciav hlau lossis kev thauj mus los ntau yam (xws li kev sib cais).

    Nyob rau hauv cov ntaub ntawv ntawm cov neeg yuav tsum tau, peb muaj peev xwm qhia kom meej cov kev cai ntawm barges los yog tankers thiab siv tshwj xeeb kev nyab xeeb / tshuaj xyuas cov qauv thiab cov kev cai.

    3. Yam tsawg kawg nkaus kom muaj nuj nqis

    Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.
