Kev Siv Cov Yeeb Yeeb PE

1. PE mining yeeb nkab
Ntawm txhua lub tshuab hluav taws xob, HDPE muaj qhov hnav zoo tshaj plaws thiab yog qhov pom tau tshaj plaws. Qhov siab dua qhov hnyav molecular, qhov hnav ntau dua-cov khoom yog, txawm tias dhau mus ntau cov ntaub ntawv hlau (xws li carbon hlau, stainless hlau, tooj daj, thiab lwm yam). Nyob rau hauv cov xwm txheej ntawm kev muaj zog corrosion thiab siab hnav, qhov kev pab cuam lub neej yog 4-6 npaug ntawm cov yeeb nkab steel thiab 9 zaug ntawm polyethylene zoo tib yam; Thiab conveying efficiency yog txhim kho los ntawm 20%. Cov nplaim retardant thiab antistatic cov khoom yog qhov zoo thiab ua tau raws li cov qauv kev xav tau. Cov kev pabcuam downhole lub neej yog ntau tshaj 20 xyoo, nrog kev lag luam zoo tshaj plaws nyiaj txiag, muaj kev cuam tshuam tsis zoo, hnav tsis kam thiab ob leeg tsis kam.

2. PE dej phwj tuaj
PE yeeb nkab rau dej phwj tuaj yeem tseem hu ua high ntom polyethylene yeeb nkab, uas txhais tau tias HDPE ua lus Askiv. Hom yeeb nkab no feem ntau siv los ua thawj txoj kev xaiv rau kev tsim kho tshuab hauv nroog, feem ntau yog siv hauv kev lim dej ntxuav kev lag luam. Vim tias nws hnav tsis kam, acid tsis kam, tiv thaiv corrosion, kub tsis kam, siab tiv taus thiab lwm yam ntxwv, nws maj mam hloov qhov chaw ntawm cov tsoos kav dej xws li cov kav hlau thiab cov kav dej hauv kev ua lag luam, tshwj xeeb vim tias cov yeeb nkab no yog lub teeb yuag thiab yooj yim rau nruab thiab txav chaw, thiab yog thawj qhov kev xaiv ntawm cov ntaub ntawv tshiab. Cov neeg siv yuav tsum tau them nyiaj tshwj xeeb rau cov ntsiab lus hauv qab no thaum xaiv cov kav dej uas ua los ntawm cov khoom no: 1. Them nyiaj tshwj xeeb rau kev xaiv ntawm cov ntaub ntawv nyoos rau cov kav dej yas. Muaj ntau txhiab qib ntawm polyethylene raw khoom, thiab muaj cov khoom raw li tsawg li ntau txhiab yuan ib tuj hauv khw. Cov khoom tsim los ntawm cov khoom siv raw no tsis tuaj yeem tsim, tsis li, kev rov ua dua yuav poob loj heev. 2. Kev xaiv ntawm cov raj xa dej yuav tsum yog nyob ntawm cov lag luam muaj txuj ci thiab cov kws tshaj lij. 3. Thaum xaiv yuav PE kav dej, tshuaj xyuas cov tuam ntxhab ntawm qhov chaw kom pom seb lawv puas muaj peev xwm ntau lawm.

3. PE dej tso dej yeeb nkab
PE kav dej rau kev xa dej yog cov khoom lag luam hloov tshiab ntawm cov kav hlau loj thiab PVC cov kav dej haus.
Lub tshuab xa dej xa dej yuav tsum dais qee qhov siab, thiab PE cob nrog lub cev nyhav thiab lub zog cov khoom siv zoo, xws li HDPE resin, feem ntau yog xaiv. LDPE cov khoom siv ua kom muaj zog tensile qis, lub zog tsis zoo tiv thaiv, ua haujlwm tsis ruaj khov, tsis tuaj yeem ruaj khov thaum lub sij hawm molding thiab kev sib txuas tsis yooj yim, yog li nws tsis tsim nyog raws li cov khoom siv ntawm cov dej xa ua yeeb nkab siab. Txawm li cas los xij, vim nws qhov ntsuas kev nyiam huv, PE, tshwj xeeb tshaj yog HDPE yas, tau dhau los ua cov khoom siv rau kev tsim cov kav dej haus. HDPE resin muaj cov roj yaj ua qis, zoo fluidity thiab kev ua haujlwm yooj yim, yog li nws cov melt index muaj ntau cov kev xaiv, feem ntau MI yog nruab nrab ntawm 0.3-3g / 10min.
