Silicon Txheej yeeb nkab Extrusion kab

Lus piav qhia luv luv:

Cov khoom siv raw ntawm silicon tube tube substrate yog high-density polyethylene, cov txheej sab hauv siv cov kev sib txhuam qis tshaj plaws coefficient silica gel khoom lubricant.Nws yog corrosion kuj, du sab hauv phab ntsa, yooj yim gas blowing cable kis tau tus mob, thiab tsawg tsim nqi.Raws li kev xav tau, ntau qhov sib txawv thiab xim ntawm cov raj me me yog tsom los ntawm sab nraud casing.Cov khoom siv rau optical cable kev sib txuas lus network system rau txoj kev loj, railway thiab lwm yam.

Kev ua tau zoo & Qhov zoo

Cov kab ntau lawm tuaj yeem paub ntau lub hauv paus kav tib lub sijhawm, kev kub ceev unwinding, thiab ceev thiab sib npaug ntawm cov txheej txheem.Synchronous traction, txiav tawm thiab tiav cov khoom coiling yog tswj los ntawm lub computer, nrog kev ua haujlwm siab thiab kev ua haujlwm zoo.

HDPE yeeb nkab yog ib qho yooj yim yas yeeb nkab ua los ntawm cov thermoplastic high-density polyethylene dav siv rau cov dej kub thiab cov pa hloov pauv.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 kub, 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).HDPE kav dej tuaj yeem ua haujlwm txaus siab nyob rau hauv qhov kub ntau 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 kab txaij xim yog muab rau ntawm 5% ntawm sab nraud.
