Cov neeg uas nquag sivPE cevkev tsim kho paub tiasPE cevnto muaj symmetrical kab nrog tib xim, xiav, daj, liab, yog li ntawd nws txhais li cas?Hauv Tuam Tshoj txoj kev lag luam yeeb nkab hauv nroog, cov kav dej xa dej thiab cov yeeb nkab roj yog ob lub lag luam loj.PE tshuaj Suav lub npe, polyethylene, PE khoom vim nws lub zog siab, kub tsis kam, corrosion resistance, non-toxic, hnav tsis kam thiab lwm yam ntxwv, yog dav siv nyob rau hauv kev lag luam dej thiab kev tsim khoom.Vim tias nws yuav tsis xeb, yog li nws yog cov yeeb nkab zoo tshaj plaws los hloov cov kav dej zoo tib yam hlau;Raws li nws siv, qhov saum npoo ntawm PE raj yog qhov txawv los ntawm cov kab sib txawv xim.Cov xim hauv qab no sawv cev rau ntau yam kev siv raws li:
1.Cov kab liab: PE mine yeeb nkab
Ntawm tag nrho cov engineering plastics, kev hnav tsis kam ntawm HDPE nyob hauv cov yas yas, qhov muag pom.Qhov siab dua qhov hnyav ntawm cov khoom siv, qhov hnav-tiv taus ntau dua, ntau dua li cov ntaub ntawv hlau (xws li carbon steel, stainless hlau, bronze, thiab lwm yam).Raws li qhov muaj zog corrosion thiab hnav siab, nws lub neej kev pabcuam yog 4-6 npaug ntawm cov yeeb nkab steel thiab 9 npaug ntawm cov polyethylene zoo tib yam.Thiab txhim kho kev sib kis tau zoo los ntawm 20%.
nplaim retardant, antistatic kev ua tau zoo, txhua yam ua tau raws li tus qauv yuav tsum tau ua.Downhole kev pab cuam lub neej ntawm ntau tshaj 20 xyoo, zoo kawg li kev lag luam cov txiaj ntsig, cuam tshuam tsis kam, hnav tsis kam, ua haujlwm ob npaug.
2.Blue kab:PE kav dej, cov kav dej, thiab cov yeeb nkab hluav taws xob
PE blowdown yeeb nkab: PE yeeb nkab siv rau tshuab tshuab kuj hu ua high-density polyethylene yeeb nkab, uas yog HDPE hauv lus Askiv.Cov yeeb nkab no feem ntau yog siv los ua cov kav dej hauv nroog engineering, feem ntau yog siv hauv: dej phwj kho kev lag luam.Vim nws hnav tsis kam, acid tsis kam, corrosion kuj, kub tsis kam, siab tsis kam thiab lwm yam ntxwv, nws tau maj mam hloov txoj hauj lwm ntawm tsoos steel yeeb nkab, cement yeeb nkab thiab lwm yam yeeb nkab nyob rau hauv kev ua lag luam, tshwj xeeb tshaj yog vim hais tias cov yeeb nkab yog lub teeb nyob rau hauv lub lag luam. hnyav thiab yooj yim rau nruab thiab txav mus los, nws yog qhov kev xaiv zoo tshaj plaws ntawm cov ntaub ntawv tshiab.
PE yeeb nkab dej: PE yeeb nkab rau dej yog hloov khoom ntawm cov yeeb nkab steel thiab PVC cov yeeb nkab dej haus.Cov yeeb nkab dej yuav tsum dais lub siab, feem ntau xaiv qhov hnyav molecular, zoo dua cov khoom ntawm PE resin, xws li HDPE resin.LDPE resin muaj lub zog tensile tsawg, tsis zoo siab tsis kam, tsis zoo rigidity, tsis muaj qhov ruaj khov thaum tsim thiab ua, thiab kev sib txuas nyuaj, nws tsis haum raws li cov khoom siv ntawm cov kav dej siab.Txawm li cas los xij, vim nws qhov ntsuas kev noj qab haus huv siab, PE, tshwj xeeb tshaj yog HDPE resin, tau dhau los ua cov khoom siv hauv kev tsim cov kav dej haus.HDPE resin muaj me me yaj viscosity, zoo fluidity thiab ua tau yooj yim, yog li cov kev xaiv ntawm nws melt index kuj dav, feem ntau MI ntawm 0.3-3g / 10min.
3.Yellow daim ntawv lo kab: PE roj yeeb nkab
PE yeeb nkab rau cov pa roj yog cov khoom hloov ntawm cov yeeb nkab steel thiab PVC roj.
Cov yeeb nkab roj yuav tsum dais lub siab, feem ntau xaiv qhov hnyav molecular, zoo txhua yam khoom ntawm PE resin, xws li HDPE resin.HDPE resin muaj lub zog tensile tsawg, tsis zoo siab tsis kam, tsis zoo rigidity, tsis muaj qhov ruaj khov thaum tsim, thiab kev sib txuas nyuaj, nws tsis haum raws li cov khoom siv ntawm cov kav dej siab.Txawm li cas los xij, LDPE, tshwj xeeb tshaj yog LLDPE resin, tau dhau los ua cov khoom siv feem ntau rau cov yeeb nkab roj vim nws qhov ntsuas kev noj qab haus huv siab.LDPE, LLDPE resin yaj viscosity yog me me, zoo fluidity, yooj yim ua, yog li kev xaiv ntau yam ntawm nws melt index yog dav, feem ntau MI ntawm 0.3-3g / 10min.
