Kev kub ceev zog txuag HDPE yeeb nkab Extrusion kab

Peb lub tuam txhab kev tshawb fawb thiab kev loj hlob ntawm lub zog txuag high-speed ntau lawm kab, haum rau high-speed polyolefin yeeb nkab extrusion. 35% kev txuag hluav taws xob thiab 1x nce hauv kev tsim khoom. Tsim tshwj xeeb tsim 38-40 L / D ntsia hlau qauv thiab cov khoom noj khoom haus ua rau cov yaj extrusion thiab plasticizing cuam tshuam zoo heev. High-torque, high-strength gearboxes xyuas kom ruaj khov ntawm cov khoom siv. Extrusion pwm thiab sizing lub tes tsho txais cov qauv tsim tshaj plaws. PLC hloov pauv zaus tswj lub tshuab nqus tsev, servo-tsav tsheb laij teb ntau lub tsheb laij teb, thiab kev kub ceev nti-tsawg cutter yog nruab nrog lub ntsuas qhov hnyav. Cov yeeb nkab extrusion hnyav yog qhov tseeb dua.

HDPE yeeb nkab yog ib qho yooj yim yas yeeb nkab ua los ntawm cov thermoplastic high-density polyethylene dav siv rau cov dej tsis kub thiab roj hloov. Nyob rau lub sijhawm tsis ntev los no, cov kav dej HDPE tau txais lawv cov kev siv dav rau kev nqa cov dej haus, cov khoom siv phom sij, ntau yam roj av, slurry, dej tua hluav taws, dej nag, thiab lwm yam. Cov kav dej polyethylene muaj keeb kwm kev pabcuam ntev thiab muaj txiaj ntsig zoo rau roj, roj, mining, dej, thiab lwm yam lag luam. Vim nws qhov hnyav qis thiab siab corrosion kuj, HDPE yeeb nkab kev lag luam loj hlob zoo heev. Xyoo 1953, Karl Ziegler thiab Erhard Holzkamp tau tshawb pom cov polyethene siab ntom ntom (HDPE). Cov kav dej HDPE tuaj yeem ua haujlwm txaus siab nyob rau hauv qhov kub ntawm -2200 F txog +1800 F. Txawm li cas los xij, kev siv cov kav dej HDPE tsis pom zoo thaum cov kua dej kub siab tshaj 1220 F (500 C).

HDPE kav yog tsim los ntawm polymerization ntawm ethylene, ib tug by-product ntawm roj. Ntau yam additives (stabilizers, fillers, plasticizers, softeners, lubricants, colorants, flame retardants, blowing agents, crosslinking agents, ultraviolet degradable additives, etc.) yog ntxiv los tsim cov yeeb nkab HDPE kawg thiab cov khoom siv. HDPE yeeb nkab ntev yog tsim los ntawm cua sov HDPE resin. Nws yog tom qab ntawd extruded los ntawm kev tuag, uas txiav txim siab txoj kab uas hla ntawm cov kav dej. Cov yeeb nkab phab ntsa tuab yog txiav txim siab los ntawm kev sib xyaw ntawm qhov loj me, qhov ceev ntawm cov ntsia hlau, thiab qhov ceev ntawm lub tsheb laij teb tawm. Feem ntau, 3-5% carbon dub yog ntxiv rau HDPE kom nws UV resistant, uas hloov HDPE kav rau hauv cov xim dub. Lwm cov xim txawv muaj tab sis feem ntau tsis siv ntau zaus. Xim lossis kab txaij HDPE yeeb nkab feem ntau yog 90-95% cov khoom siv dub, qhov twg cov xim muaj xim yog muab rau ntawm 5% ntawm sab nraud.
