Muaj pes tsawg hom kev tsim khoom yas ua, muaj kev xyaum ua li cas, muaj kev zoo dua lossis kev tsis zoo?
Tej zaum yas muaj extrusion, txhaj, molding, tshuab molding, yob-casting, casting, dip yas thiab lwm yam molding dab, raws li cov ntaub ntawv sib txawv thiab cov khoom tshwj xeeb, nws tsis yooj yim hais qhov zoo los yog disadvantages.Kuv siv PE txoj yas ua tus qauv hais yooj yim, PE tuaj yeem ua los ntawm ntau txoj kev sib txawv heev.Txawm ethylene ua cov ntsiab raw khoom thiab propylene, 1-butene thiab hexene li copolymers, nyob rau hauv qhov kev txiav txim ntawm catalyst, slurry polymerization lossis roj theem polymerization txheej txheem saws, ua rau polymers tau los ntawm flash evaporation, sib cais, ziab, granulation thiab lwm yam dab, thiab cov khoom uas muaj cov khoom ua tsis tau zoo.Qhov xws li ntawv extrusion, zaj duab xis extrusion, yeeb nkab lossis profile extrusion, tshuab molding, txhaj tshuaj thiab yob molding. Extrusion: qib siv hauv extrusion ntau lawm feem ntau tau yaj Performance index tsawg tshaj li 1 thiab MWD ntawm nruab nrab mus rau qhov dav.Nyob rau hauv tus txheej txheem ntawm kev ua, lub looj le lub zog ntawm lub cev muaj peev xwm ua tau nrog qis qis MI.Wider MWD qib tau zoo dua vim yog lawv muaj ntau dua kev ceev, txo kev siab dua thiab txo kev sib tawg kom tawg dua.Yuav muaj ntau yam khoom siv hluav taws xob, xws li xaim, cable, hose, cov yeeb nkab thiab cov ntawv profiles.Qhov daim ntawv sau sib txawv ntawm qhov me me hauv cov kav dej rau cov pa roj ua kom muaj roj kav hlau nrog cov kab uas muaj 48in rau industrial thiab cov kav dej hauv nroog loj.Cov phab ntsa ntawm phab ntsa tau loj hlob sai heev li hloov chaw rau cov dej nag tso dej thiab lwm cov kav dej phwj tuaj. Thaum tshav kub sib dhos ua kom sov ntau ntawm cov picnic txias yog ua los ntawm PE thiab muaj lub zog, lub cev nyhav thiab lub cev muaj zog. Lwm daim ntawv thiab cov khoom sib sau ua ke muaj xws li fender, tank liner, tais hau, thauj lub thawv thiab tank.Thaum muaj coob tus ceev Cov ntaub ntawv cog qoob loo siv rau hauv cov zos mulch lossis poolside, uas yog los ntawm kev tuav pov hwm, kev quav tshuaj thiab kev tiv thaiv ntawm MDPE.Fax: tshaj li ib feem peb ntawm hdpepe uas muag hauv tebchaws United Lub xeev yog siv cov tshuab fwj moulds.These ntau ntawm cov fwj tshuaj uas muaj tshuaj dawb, roj, xab npum, mis nyuj thiab dej tuaj rau cov tub yees loj, cov roj tsheb tsheb thiab cov kaus poom.Qhov yam ntxwv ntawm lub tshuab qib molding, xws li lub zog lub zog, es-cr thiab lub zog , zoo ib yam li cov neeg siv hauv cov hlau thiab thermal daim ntawv sau npe, thiaj li zoo sib xws tuaj yeem tau txais yuav los ua ke.Qhov tshuaj tiv thaiv - tshuab moulding yog siv los ua cov ntim me me (tsawg dua 16oz) ntim tshuaj, tsuaj zawv plaub hau thiab tshuaj pleev ib ce. cov txheej txheem no yog tias lub raj mis tsuas yog raug tshem tawm ntawm lub kaum tsev, thiab tsis tas yuav siv txoj kev ua tiav tom qab zoo li txoj kev tshuab molding. Txawm li cas los xij MWD qib qis siv los txhim kho qhov dej tob, qhov dav dav MWD qib feem ntau yog siv.HDPE muaj ntau hom kev siv, xws li siv tau los ntawm cov dej khov nab kuab rau 5-gsl, haus ib feem ntawm cov hluav taws xob tsim hluav taws xob HDPE.Qhov kev txhim kho ntawm cov tshuaj moldin g yog 5 ~ 10, thiab muaj cov qib fluidity qib uas muaj qhov tsis muaj zog thiab muaj kev ua haujlwm siab dua.Qhov twg muaj cov khoom noj txhua hnub thiab khoom ntim khoom ntim; roj tso tsheb hlau luam thiab 90-gal khoob khib nyiab. Cov khoom siv hauv cov txheej txheem no feem ntau yog txau mus rau cov khoom siv hmoov qhuav thiab ntws hauv cov cua kub. Roll-molding SIV ob hom PE: kev dav dav thiab kev sib tw. Lub hom phiaj MDPE / HDPE yog 0.935 txog 0.945g / CC, nrog cov MWD nqaim, ua rau cov khoom muaj feem xyuam thiab qis qis tshaj, nws qhov kev ntsuam xyuas tob dua yog feem ntau ntawm 3-8.Higher cov ntawv qib MI feem ntau tsis siv rau vim tias lawv tsis muaj qhov cuam tshuam thiab los tiv thaiv kev nyuaj siab ntxhov plawg tawm ntawm cov khoom zoo siab los ntawm kev yob cov khoom siv.Qhov kev ua haujlwm dov rau daim ntaub ntawv yas siv kev siv nws cov khoom sib txawv ntawm cov khoom sib txuas ntawm cov khoom siv sib tw. Cov qib no hauv thawj theem ntawm molding lub voj voos, lub cev, lub cev zoo, thiab tom qab ntawd hla txuas mus rau nws cov kev tiv thaiv zoo ntawm kev nyuab siab, toughness.Wear tsis kam thiab huab cua tiv thaiv.Crosslinked PE yog tshwj xeeb rau cov ntim loj, xws li 500-gal tshuaj lom neeg tso dej mus rau 20,000-gal agricultural cia Tuab cua tshuab: PE zaj duab xis ua yog feem ntau ua los ntawm cov tshuab luam yeeb zoo tib yam lossis kab rov tav cov duab ua rau ntau tshaj plaws. Feem ntau PE yog siv hauv cov yeeb yaj kiab thiab yuav siv rau qhov tsis sib luag PE (LDPE) lossis cov kab uas tsis sib haum PE (LLDPE). HDPE zaj duab xis qib feem ntau yog siv rau hauv cov chaw uas yuav tsum tau muaj zog tensile zog thiab zoo impermeability.Piv txwv li, HDPE zaj duab xis feem ntau yog siv rau hauv cov hnab, cov zaub mov thiab cov ntim zaub mov.
