R Extrusion: Cov qhab nia siv rau extrusion ntau lawm feem ntau muaj qhov ua tiav ntawm qhov qis dua 1 thiab nruab nrab rau MWD dav. Tsawg MI muab ib qho kev tsim nyog yaj lub zog thaum kev ua. Qhov qeb siab tshaj MWD yog qhov tsim nyog dua rau kev rho tawm vim lawv qhov kev tsim tawm ntau dua, kev tuag qis dua thiab ua kom lub siab yaj txhaws.
PE muaj ntau daim ntawv thov extrusion xws li xaim, cables, hoses, tubing thiab profiles. Kev siv cov yeeb nkab li ntawm ntu me-ntu daj rau cov roj nkev mus rau cov yeeb yaj kiab dub rau phab ntsa rau kev lag luam thiab cov kav dej hauv nroog txog 48 hauv. nrawm.
Cov ntawv txheeb thiab cov thermoforming: Cov thermoformed cov kab ntawm ntau qhov loj ntawm cov phoj ua luam dej-txias yog cov thoob yas ua los ntawm PE uas yog cov tawv, sib thiab ua kom ntev. Lwm cov ntawv sau thiab cov khoom siv thermoformed muaj xws li fender, roj tsheb ciav hlau, tsheb thaiv tais diav, thawv xa khoom thiab cov kaus poom. Coob tus ntawm daim ntawv thov loj hlob sai yog nyob hauv cov nyom lossis pas dej hauv qab, uas yog raws li MDPE cov nyom, tshuaj lom neeg tsis kam thiab impermeability.
▲ Tshuab moulding: HDPE 1/3 lossis ntau dua muag hauv Asmeskas yog siv rau tshuab moulding. Cov no suav nrog cov fwj muaj cov tshuaj dawb, lub cev muaj roj, tshuaj ntxuav tais diav, mis thiab dej haus rau cov tub yees loj, tsheb tso tsheb roj thiab cov poom. Tshuab moulding qib cov yam ntxwv xws li yaj lub zog, ES-CR thiab tawv yog zoo ib yam li cov siv rau ntawv thiab thermoforming kev siv, yog li qib zoo sib xws yuav siv tau.
Kev txhaj tshuaj tshuab moulding yog nquag siv los ua cov ntim me dua (tsawg dua 16 oz) rau ntim cov tshuaj ntim tshuaj, tshuaj zawv plaub hau thiab tshuaj pleev ib ce. Ib qho zoo ntawm cov txheej txheem no yog lub tshuab tsis zoo no feem ntawm lub hwj, tsis tas yuav tsum ua tom qab ua tiav zoo li cov tshuab moulding. Txawm hais tias qee qib MWD nqaim tau siv los txhim kho qhov ua tiav saum npoo, qhov nruab nrab mus rau thoob MWD cov qhab nia tau siv.
Molding Kev txhaj tshuaj molding: HDPE muaj ntau cov ntawv thov xws li los ntawm kev siv rov qab tau cov khob haus cawv mus rau 5-gsl poom, uas haus 1/5 ntawm cov ua HDPE. Kev txhaj tshuaj molding qib feem ntau muaj qhov ntsuas ntawm 5 mus txog 10, thiab muaj qib zoo dua mus kawm nrog qib qis dua qhov kev nruj thiab kev ua kom tiav. Kev siv nrog txhua yam khoom siv txhua hnub thiab zaub mov nyias ntim khoom ntim khoom; tawv, ruaj zaub mov thiab xim kaus poom; siab tiv rau ib puag ncig kev ntxhov siab tawg daim ntaub ntawv siv xws li cov cav tsheb me me roj tsheb thiab 90-gal thoob khib nyiab.
Molding Kev hloov pwm: Cov ntaub ntawv siv cov txheej txheem no feem ntau pulverized rau hauv cov hmoov cov ntaub kom yaj thiab ntws hauv lub voj voog thermal. Kev sib hloov mentsis siv ob hom PE: cov qauv dav dav thiab crosslinkable. Cov hom phiaj dav dav MDPE / HDPEs feem ntau muaj qhov muaj ntau yam nyob ntawm 0.935 txog 0.945 g / cc thiab muaj qhov MWD nqaim rau qhov cuam tshuam loj thiab tsawg heev kev ua tsov rog, nrog cov maim taw qhia ib txwm li ntawm 3-8. Cov qhab nia qib siab MI feem ntau tsis muaj peev xwm siv tau vim tias lawv tsis muaj qhov xav tau thiab qhov cuam tshuam txog kev cuam tshuam ib puag ncig ntawm cov lus rotomoulded.
Cov kev ua haujlwm siab tig moulding siv cov yam ntxwv ntawm lawv cov qhab nia sib kis crosslinkable. Cov qhab nia no yog kua dej nyob hauv thawj theem ntawm lub voj voog molding thiab tom qab ntawd sib txuas los tsim lawv qhov kev tawm tsam zoo tshaj plaws rau ib puag ncig kev ntxhov siab thiab tawv. Abrasion tsis kam thiab huab cua tsis kam. Crosslinkable PE tsis zoo tshwj xeeb rau kev siv hauv cov thawv loj ntau los ntawm 500-gal mus rau ntau qhov chaw tso kua tshuaj mus rau 20,000-gal ua liaj ua teb cia tso tsheb hlau luam.
▲ Zaj duab xis: PE zaj duab xis ua yog feem ntau ua los ntawm cov tshuab pa zoo tib yam txheej txheem ua los yog tiaj tus txheej txheem ua kom tiav. Cov PE feem ntau yog siv rau cov zaj duab xis, dav dav dav ntom PE (LDPE) lossis kab qis tsis txaus PE (LLDPE). HDPE zaj duab xis qib feem ntau yog siv qhov twg superior stretchability thiab zoo heev lub zog teeb meem xav tau. Piv txwv li, HDPE zaj duab xis feem ntau yog siv rau hauv cov hnab muag khoom muag, hnab muag khoom noj, thiab pob zaub mov ntim. https://www.fhpails.com/
