High density polyethylene txheej txheem

PE tuaj yeem tsim tau siv ntau hom kev sib txawv. Siv ethylene ua cov khoom siv tseem ceeb, propylene, 1-butene, thiab hexene li copolymer, nyob rau hauv qhov kev txiav txim ntawm catalyst, slurry polymerization los yog roj theem polymerization txheej txheem yog siv, thiab cov polymerization tshwm sim flashed, sib cais, qhuav. , granulated, thiab lwm yam txheej txheem kom tau txais cov khoom tiav nrog cov khoom sib xws. Xws li cov txheej txheem xws li ntawv extrusion, zaj duab xis extrusion, yeeb nkab lossis profile extrusion, tshuab moulding, txhaj tshuaj molding thiab rotational molding. HDPE yog tsim rau ntau yam molding txheej txheem ntawm thermoplastic molding thiab muaj zoo molding processability, xws li txhaj molding, extrusion, tshuab moulding, rotational molding, txheej, foaming txheej txheem, thermoforming, tshav kub sealing, tshav kub vuam, thiab lwm yam.
Extrusion: Qib siv nyob rau hauv extrusion ntau lawm feem ntau muaj ib tug yaj index tsawg tshaj li 1 thiab ib tug nruab nrab mus rau dav MWD. Thaum ua tiav, qis MI tuaj yeem ua tiav lub zog zoo. Cov qib MWD dav dua yog qhov tsim nyog rau extrusion vim tias lawv muaj ntau dua qhov nrawm dua, txo qis kev tuag thiab txo qis rau cov pob txha tawg.
PE muaj ntau yam kev siv extrusion xws li xov hlau, cables, hoses, kav thiab profiles. Cov ntawv thov cov yeeb nkab muaj ntau yam los ntawm cov kav dej me me rau cov pa roj carbon monoxide rau cov kav dej tuab-walled dub rau cov kav dej hauv nroog thiab hauv nroog. Loj txoj kab uas hla hollow phab ntsa kav yog loj hlob sai raws li ib tug hloov rau cua daj cua dub ntws thiab lwm yam kav dej ua los ntawm cov pob zeb.
Sheet thiab Thermoforming: Cov thermoformed liners ntawm ntau lub picnic txias txias yog tsim los ntawm PE, uas muaj zog, lub teeb yuag thiab durability. Lwm cov ntawv thiab cov khoom siv thermoformed muaj xws li fenders, tank liners, pan guards, shipping thawv thiab tanks. Ib daim ntawv thov loj thiab loj hlob sai yog mulch lossis pas dej decking, uas yog raws li MDPE rau nws cov tawv tawv, tshuaj tiv thaiv thiab impermeability.
Tshuab moulding: Ntau tshaj 1/3 ntawm HDPE muag hauv Tebchaws Meskas yog siv rau tshuab moulding. Cov no muaj xws li cov fwj uas muaj tshuaj dawb, roj cav, tshuaj ntxuav tes, mis nyuj thiab dej distilled mus rau lub tub yees loj, lub tsheb roj tank thiab cov kaus poom. Cov khoom ntawm cov tshuab moulding qib, xws li yaj lub zog, ES-CR thiab toughness, zoo ib yam li cov siv rau daim ntawv thiab thermoforming, yog li cov qib zoo sib xws tuaj yeem siv tau.
Kev txhaj tshuaj molding feem ntau yog siv los tsim cov thawv me me (tsawg dua 16oz) rau ntim tshuaj, tshuaj zawv plaub hau thiab tshuaj pleev ib ce. Ib qho txiaj ntsig ntawm cov txheej txheem no yog cov ces kaum ntawm lub raj mis raug tshem tawm, tshem tawm qhov xav tau ntawm kev ua tiav cov kauj ruam zoo li lub tshuab tshuab moulding. Cov qib nruab nrab mus rau dav MWD feem ntau yog siv, txawm hais tias muaj qee qhov nqaim MWD qib siv los txhim kho saum npoo.
Txhaj Moulding: Saib "Material Properties" saum toj no.
Rotational molding: Cov khoom siv txoj kev ua no feem ntau crushed rau hauv cov khoom siv hmoov, uas yog yaj thiab ntws hauv lub voj voog thermal. Rotational molding siv ob hom PE: lub hom phiaj dav dav thiab sib txuas. General-purpose MDPE/HDPE feem ntau muaj qhov ntom ntom ntawm 0.935 txog 0.945g/CC, muaj qhov nqaim MWD, muab cov khoom lag luam muaj kev cuam tshuam thiab tsawg kawg ntawm warpage, thiab nws qhov ntsuas qhov ntsuas kub yog feem ntau 3-8. Cov qib MI siab dua feem ntau tsis haum vim tias lawv tsis muaj qhov cuam tshuam thiab ib puag ncig kev ntxhov siab tawg ua haujlwm xav tau hauv cov khoom siv rotomolded.
Zaj duab xis: PE zaj duab xis ua feem ntau siv cov tshuab cua tshuab ua haujlwm lossis kev ua haujlwm cam khwb cia extrusion. PE feem ntau yog siv rau hauv cov yeeb yaj kiab, xws li lub hom phiaj tsis tshua muaj PE (LDPE) lossis linear low-density PE (LLDPE) muaj. HDPE zaj duab xis qib feem ntau yog siv qhov twg superior stretchability thiab zoo heev impermeability yuav tsum tau. Piv txwv li, cov yeeb yaj kiab HDPE feem ntau yog siv rau hauv cov hnab ntim khoom, hnab ntim khoom noj, thiab ntim khoom noj.
