PE tuaj yeem ua tiav thiab tsim nyob rau hauv ntau txoj kev.Siv ethylene los ua cov khoom siv tseem ceeb, propylene, 1-butene thiab hexene li copolymer, nyob rau hauv qhov kev txiav txim ntawm catalysts, siv slurry polymerization los yog roj polymerization txheej txheem, cov polymer tau los ntawm flash evaporation, sib cais, ziab thiab granulation kom tau raws li cov khoom sib xws. cov khoom tiav.Qhov no suav nrog cov txheej txheem xws li ntawv extrusion, zaj duab xis extrusion, yeeb nkab lossis profile extrusion, tshuab moulding, txhaj tshuaj molding, thiab yob molding.
Extrusion: Qib siv rau extrusion ntau lawm feem ntau yaj qhov ntsuas tsawg dua 1, MWD yog nruab nrab dav.Tsawg MI thaum lub sijhawm ua haujlwm ua rau muaj qhov tsim nyog yaj lub zog.Cov qib MWD dav dua yog qhov zoo dua rau cov khoom siv extrusion vim tias lawv muaj ntau dua tus nqi, qis dua qhov qhib siab, thiab qis qis qis dua.
PE muaj ntau yam kev siv extrusion xws li xov hlau, cables, hoses, tubing thiab profiles.Daim ntawv thov cov kav dej muaj ntau yam los ntawm cov raj me me daj rau cov roj ntsha mus rau cov hlab ntsha tuab tuab 48 ntiv hauv txoj kab uas hla rau cov kav dej hauv nroog thiab hauv nroog.Txoj kab uas hla loj hollow phab ntsa cov kav dej tau tsim kho sai raws li lwm txoj hauv kev rau cua daj cua dub ntws thiab lwm yam kev ua vaj tse.
1.Sheet thiab Thermoforming: Thermoforming hauv ob sab phlu ntawm ntau yam loj picnic txias txias yog ua los ntawm PE rau toughness, lub teeb yuag thiab durability.Lwm cov ntawv thiab cov khoom siv thermoforming muaj xws li fenders, tank linings, daim hlau thiab phiab guards, shipping thawv thiab tso tsheb hlau luam.Raws li qhov tseeb hais tias MDPE yog tawv, resistant rau tshuaj corrosion thiab impermeable, ib tug loj thiab loj hlob tus naj npawb ntawm daim ntawv thov yog mulch los yog pas dej ua ke hauv qab Muri.
2.Blow molding: Ntau tshaj li ib feem peb ntawm HDPE muag hauv Tebchaws Meskas yog rau kev siv tshuab molding.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, tsheb roj tank thiab number case cartridges.Tshuab moulding qib muaj cov kev ua tau zoo xws li yaj lub zog, ES-CR thiab toughness zoo ib yam li cov siv rau daim ntawv thiab cov ntawv thov thermoforming, yog li cov qib zoo sib xws tuaj yeem siv tau.
Kev txhaj tshuaj molding feem ntau yog siv los ua cov ntim me me (tsawg dua 16 ooj) rau ntim tshuaj, tshuaj zawv plaub hau, thiab tshuaj pleev ib ce.Qhov kom zoo dua ntawm cov txheej txheem no yog tias lub raj mis yog tsim los ntawm kev tshem tawm lub raj mis tsis siv neeg, tshem tawm qhov xav tau rau cov kauj ruam tom qab ua tiav ib txwm cuam tshuam nrog cov txheej txheem tshuab molding.Txawm hais tias qee qhov nqaim MWD qib tau siv los txhim kho qhov chaw tiav, cov qib nruab nrab mus rau dav MWD feem ntau siv.
3.Kev txhaj tshuaj molding: HDPE muaj ntau daim ntawv thov, los ntawm reusable nyias-walled haus khob mus rau 5-gsl cov kaus poom uas haus ib feem tsib ntawm HDPE ua domestically.Cov qib txhaj tshuaj feem ntau muaj qhov ntsuas qhov ntsuas ntawm 5 txog 10 thiab muab cov qib qis qis rau cov tawv thiab cov qib siab dua rau kev ua haujlwm.Kev siv suav nrog cov khoom siv niaj hnub thiab cov khoom noj nyias phab ntsa ntim;Cov kaus poom zaub mov tawv thiab cov kaus poom pleev xim;Kev ua haujlwm siab rau ib puag ncig kev ntxhov siab tawg daim ntaub ntawv xws li lub cav me me roj tso tsheb hlau luam thiab 90 nkas loos thoob khib nyiab.
4.Rolling: Cov ntaub ntawv siv cov txheej txheem no feem ntau yog crushed rau hauv cov ntaub ntawv hmoov uas tuaj yeem yaj thiab ntws hauv lub voj voog thermal.Ob hom PE yog siv rau dov: dav dav thiab sib txuas.Lub hom phiaj dav dav MDPE / HDPE feem ntau muaj qhov ntom ntom ntawm 0.935 txog 0.945 g / CC ntau yam nrog nqaim MWD, ua rau muaj kev cuam tshuam cov khoom lag luam nrog tsawg kawg warp thiab melt index ntau ntawm 3-8.Cov qib siab dua MI feem ntau tsis haum vim tias lawv tsis muaj qhov cuam tshuam thiab ib puag ncig kev ntxhov siab tawg yuav tsum tau ua rau cov khoom yob-muab.
Kev ua haujlwm siab dov daim ntawv thov siv qhov zoo ntawm nws cov khoom tshwj xeeb ntawm cov qib sib txuas sib txuas.Cov qib no ntws tau zoo thaum thawj feem ntawm lub voj voog molding thiab tom qab ntawd sib txuas los tsim lawv cov kev ntxhov siab zoo ib puag ncig kev tiv thaiv thiab toughness.Hnav thiab huab cua tsis kam.Crosslinked polyethylene yog tshwj xeeb tshaj yog haum rau ntim loj, los ntawm 500 nkas loos tso tsheb hlau luam siv los thauj ntau yam tshuaj mus rau 20,000 nkas loos ua liaj ua teb tso tsheb hlau luam.
5.Film: PE zaj duab xis ua feem ntau siv cov txheej txheem tshuab tshuab ua los yog cov txheej txheem ca extrusion.PE feem ntau yog rau cov yeeb yaj kiab nyias thiab tuaj yeem siv nrog Universal Low Density PE (LDPE) lossis linear Low Density PE (LLDPE).HDPE zaj duab xis qib feem ntau yog siv qhov zoo tshaj plaws tensile zog thiab zoo heev impermeability yuav tsum tau.Piv txwv li, HDPE zaj duab xis feem ntau yog siv rau hauv cov hnab ntim khoom, hnab ntim khoom noj thiab ntim khoom noj.
