Kev siv PE yeeb nkab

1. PE mining yeeb nkab
Ntawm tag nrho cov engineering plastics, HDPE muaj qhov hnav tsis kam thiab yog qhov pom zoo tshaj plaws.Qhov siab dua qhov hnyav molecular, cov khoom hnav-tiv taus ntau dua, txawm tias muaj ntau yam khoom siv hlau (xws li carbon steel, stainless hlau, bronze, thiab lwm yam).Nyob rau hauv cov xwm txheej uas muaj zog corrosion thiab hnav siab, kev pab cuam lub neej yog 4-6 npaug ntawm cov yeeb nkab steel thiab 9 npaug ntawm cov polyethylene zoo tib yam;Thiab lub conveying efficiency yog txhim kho los ntawm 20%.Cov nplaim retardant thiab antistatic zog yog qhov zoo thiab ua tau raws li tus qauv yuav tsum tau ua.Lub downhole kev pab cuam lub neej yog ntau tshaj 20 xyoo, nrog zoo kawg li kev lag luam cov txiaj ntsig, cuam tshuam tsis kam, hnav tsis kam thiab ob chav ua haujlwm.

2. PE yeeb nkab
PE yeeb nkab rau cov kav dej phwj kuj tseem hu ua high density polyethylene yeeb nkab, uas txhais tau tias HDPE hauv lus Askiv.Cov yeeb nkab no feem ntau yog siv los ua thawj qhov kev xaiv rau kev tsim vaj tsev hauv nroog, feem ntau yog siv hauv kev kho dej phwj hauv kev lag luam.Vim nws hnav tsis kam, acid tsis kam, corrosion kuj, kub tsis kam, siab tsis kam thiab lwm yam ntxwv, nws maj mam hloov txoj hauj lwm ntawm ib txwm kav xws li steel kav thiab cement kav nyob rau hauv lub lag luam, tshwj xeeb tshaj yog vim hais tias cov yeeb nkab no yog lub teeb nyob rau hauv hnyav. thiab yooj yim rau nruab thiab txav mus los, thiab yog thawj qhov kev xaiv ntawm cov ntaub ntawv tshiab.Cov neeg siv yuav tsum tau xyuam xim tshwj xeeb rau cov ntsiab lus hauv qab no thaum xaiv cov kav dej ua los ntawm cov khoom siv no: 1. Ua tib zoo saib xyuas cov khoom siv raw rau cov kav dej yas.Muaj ntau txhiab qib ntawm polyethylene raw cov ntaub ntawv, thiab muaj cov ntaub ntawv raw li tsawg li ob peb txhiab yuan ib tuj hauv khw.Cov khoom tsim los ntawm cov khoom siv raw no tsis tuaj yeem tsim kho, txwv tsis pub, rov ua haujlwm poob yuav loj heev.2. Kev xaiv cov kav raj xa dej yuav tsum ua raws li cov neeg tsim khoom raug cai thiab cov kws tshaj lij.3. Thaum xaiv yuav cov kav dej PE, tshuaj xyuas cov chaw tsim khoom ntawm qhov chaw kom pom tias lawv muaj peev xwm ntau lawm.

3. PE kav dej
PE kav dej rau dej yog cov khoom siv hloov cov kav dej ib txwm siv thiab cov kav dej PVC.
Cov yeeb nkab dej yuav tsum dais qee qhov siab, thiab PE resin nrog qhov hnyav molecular thiab cov khoom siv zoo, xws li HDPE resin, feem ntau yog xaiv.LDPE resin muaj lub zog tensile tsis tshua muaj zog, tsis zoo siab tsis kam, tsis zoo rigidity, tsis muaj qhov ruaj khov thaum lub sij hawm molding thiab kev sib txuas nyuaj, yog li nws tsis haum raws li cov khoom siv ntawm cov kav dej siab.Txawm li cas los xij, vim nws qhov ntsuas kev nyab xeeb siab, PE, tshwj xeeb tshaj yog HDPE resin, tau dhau los ua cov khoom siv los ua cov kav dej haus.HDPE resin muaj tsawg yaj viscosity, zoo fluidity thiab yooj yim ua, yog li nws melt index muaj ntau yam kev xaiv, feem ntau MI yog nruab nrab ntawm 0.3-3g / 10min.
