PND: seev suab ntawm abbreviations. HDPE yeeb nkab

Kuj nyuam qhuav regained nws chaw ib tug khoom xws li HDPE. Piav qhia txog cov abbreviations yog raws li nram no: tsis muaj-density polyethylene. Yeeb Nkab ua therefrom, raws li siv nyob rau hauv no technology yog ib tug ntsia hlau extrusion hom nruam. Cov kev tso cai rau kom muab tau cov khoom uas muaj nws tus yam ntxwv.

Nta ntawm HDPE-kav

Kav yog hom phiaj haum rau cov thauj kua thiab roj cua. Lawv muaj kev koom siv, Yog hais tias tsim nyog, los tiv thaiv lub cables nteg nyob rau hauv lub ntiaj teb strata. Qhov no siv yog vim hais tias cov IPA muaj rigidity thiab lub dag lub zog. Nyob rau hauv tas li ntawd, tsawg-siab polyethylene resistant mus rau sab nraud, nrog rau weathering, tej yam. Cov khoom yuav siv tau thaum pw lub sab nraud thiab sab hauv dej systems.

Lwm zoo dua ntawm HDPE kav (transcript - High Ceev Polyethylene) yog ib tug uas tsis muaj nqi, uas yog vim lub fact tias feem ob raw cov ntaub ntawv siv nyob rau hauv ntau lawm. Yog li, zus tau tej cov piav cov yeeb nkab yuav pab tau kom qhov zoo li theem nrab cov kev pab tsis tuaj mus rau qhov zoo li pov tseg. Kav ua los ntawm HDPE yuav ua tau txawv heev txoj kab uas hla, uas tso cai rau lawv siv nyob rau hauv ntau yam teb.

HDPE kav pluses

HDPE yeeb nkab (transcript yog twb paub tus nyeem ntawv) muaj ntau yam zoo. Nyob rau hauv tas li ntawd mus rau saum toj, peb yuav paub qhov txawv txawm ib tug ncaj lub sij hawm ntev ntawm lub lag luam. Kev sib piv, cov kav dej ua los ntawm steel, lawv yog siv nyob rau hauv 3 los yog txawm 5 sij hawm me me piv rau lub IPA-khoom. Material kiag li tsis ntshai tshuaj thiab corrosion dab. Thaum interacting nrog lub txhoj puab heev ib puag ncig ntawm cov yeeb nkab rau ib ntev lub sij hawm yuav tsis poob lawv lub peev xwm. Lawv muaj ib tug uas tsis muaj thermal conductivity theem, uas yog vim li cas rau ntawm qhov chaw tsis tshwm condensate.

Cov khoom ntawm HDPE (seev suab ntawm abbreviations, los ntawm txoj kev, thiab pab cov neeg nyob rau ntawm lub lub sij hawm ntawm yuav khoom ntawm cov khoom) tsis yuav tsum tau cathodic tiv thaiv rau tso hluav taws xob cables. Cov phab ntsa hauv cov kav dej yog saj zawg zog txaus, uas yog vim li cas yog tsis muaj kev pheej hmoo tias cov khoom tawg thaum lub sij hawm khov rau hauv cov kua. Thauj, tshem khoom thiab pawg cov kav dej yog heev yooj yim, vim hais tias lawv muaj ib tug heev tsawg ceeb thawj.

Ib suam ntawm HDPE-kav

Yog hais tias koj xav mus yuav cov high-zoo HDPE-yeeb nkab, koj yuav tsum xaiv ib tug uas yog ua nyob rau hauv raws li GOST 18 599-83. Cov no cov khoom tej zaum yuav yog li ntawd-hu ua hnyav kav, uas yog denoted uas sau tias "T". Cov khoom tej zaum yuav nruab nrab, los ntawm qhov hnyav, raws li zoo raws li theem nrab lub teeb, nyob rau hauv xws li ib tug cov ntaub ntawv, cov chaw tsim tshuaj paus yuav tsum xaiv lawv cim "C" thiab "SL", ntsig txog. Yog hais tias lub raj yog ua kom, ces koj yuav pom nws cim "zes."

Hom HDPE-khoom

HDPE yeeb nkab (transcript - tsawg ceev polyethylene) yuav tau ua nrog corrugated los yog tus phab ntsa. Tsis ntev los no hauj kav tau ib tug hluas txheej, thiab lawv yuav tsum tau yuav nyob rau hauv coils. Ib lwm embodiment muaj ib tug ob-txheej yeeb nkab qauv. Nyob rau txheej nto ntawm discernible npoo, uas yog tsim los tiv thaiv cov neeg kho tshuab tej yam puab txheej. Tej khoom uas yog feem ntau siv thaum txhim kho lub tshuab ua underground.

kheej ntawm daim ntawv thov

Lug siv nyob rau hauv lub lwm cov kev siv technology tshiab Wells, thiab yog hais tias tsim nyog los ua tus cable los ua ke thiab hlau HDPE yeeb nkab. Seev suab no tus nqi pab rau peb kom peb to taub hais tias lub hauv paus ntawm qhov khoom yog high-zog yas. Cov khoom uas muaj lug siv ntawm chaw ua hauj lwm nyob rau hauv ib tug lub ntiajteb txawj nqus dej sab nraud systems. Lawv yog cov ncaj ntau nyob rau hauv tej yam kev mob ntawm suburban cheeb tsam thiab nyob rau hauv kev tsim kho ntawm tus kheej lub tsev. Lawv yog cov nrov ntawm tau txais kev pab, uas yuav mus npaj zais installation hluav taws xob, uas siv rau cov neeg mob nyob rau hauv uas lub system yuav tsum mus nkaum qab los xij ntawm phab ntsa ntub dej, nws yuav ua tau ob qho tib si pob zeb phab ntsa thiab tsa plag tsev.

HDPE-khoom - kev tiv thaiv ntawm ib tug hluav taws xob cable

Muaj ntau ntau piav tej yam tseem ceeb, thiab sib txawv kiag li los ntawm cov seev suab ntawm lub IPA. Tshuaj, piv txwv li, muab nws txhais - puas siab puas ntsws hauv tsev kho mob, uas tsis yog yuav tsum tau meej pem nrog poelietilenom tsis tshua muaj siab.

Kav ua los ntawm high-density polyethylene siv nyob rau hauv tandem kuj yuav hluav taws xob cables. Tube zoo tiv thaiv cov cable los ntawm cov neeg kho tshuab kev puas tsuaj. Yog hais tias lub cable rwb thaiv tsev yog puas, lub raj yuav tiv thaiv ib tug neeg los ntawm hluav taws xob poob siab. Thaum muaj xwm ceev qhov teeb meem no tau piav tej zaum yuav tshwm sim ib tug luv luv Circuit Court, uas ua rau ib tug tua hluav taws, nyob rau hauv uas cov ntaub ntawv hauv cov yeeb nkab yuav tiv thaiv tau tus kab ntawm cov hluav taws.

kev yam ntxwv

Muaj ntau cov xav nyob rau hauv ua ntej yuav nriav transcript HDPE-f. Kws txawj paub hais tias qhov no qhia tau hais tias ua ntej koj cov yeeb nkab uas ua los ntawm cov uas tsis muaj kev ceev polyethylene muaj ib lub lwm txoj kab uas hla, uas yog denoted los ntawm tsab ntawv "f". Ua ntej yuav nws yog ib qho tseem ceeb them sai sai tsis tsuas yog nyob rau hauv cov ntaub ntawv, tab sis kuj nyob rau hauv cov yam ntxwv yuav tsum tau ntsib los ntawm cov khoom. Yog li, Yog hais tias koj xav mus yuav ib tug tus raj, tus nto yuav tsum tsis txhob muaj teeb meem nyob rau hauv daim ntawv ntawm tshwv, chipping, blistering thiab ntes. Koj yuav tsum tsis txhob tso lub puab nto ntawm cov yeeb nkab. Qhov no kev txhawj xeeb kev thiab kav dej khoom. Nyob rau hauv domestic hauv paus yuav tsum tsis txhob yuav hillocks thiab nram hav, raws li lawv tej zaum yuav ua ib qho chaw khuam thaum threading cable.

IPA-tube, seev suab (inch 110) uas yog hais saum toj no, yuav tsum muaj nyob rau hauv ncaj lengths. Nrog rau kev hwm mus hlab, lub lub cheeb ntawm uas tsis pub tshaj 90 hli, lawv siv coils. Yog hais tias koj xav tau los yuav kav nyob rau hauv ncaj lengths, lawv ntev yuav ua tau li 5-12 m. Tab sis lub permissible sib txawv los ntawm no ntev, uas yuav tsum tsis txhob ntau tshaj 2%.

Pem teb technology

IPA-f (transcript abbreviations - tsawg ceev polyethylene) yuav tsum tau pw dua ib tug dav kub ntau. Txawm li cas los, tus nqi qis tshaj Harbor yuav tsum tsis txhob yuav tsawg tshaj li ^-30 ° C. Txawm li cas los, ib co kev txwv tseem muaj, lawv pw nyob rau hauv lub fact tias peb yuav tsis las sab hauv chaw ntawm cov kav dej extraneous kua, cov roj, av thiab lwm yam. Tom qab tso qhov no heev yuav tsum tsis txhob tso cai, dab tsi ntsuas yog npaum li cas yuav muab thiab sealing hais nyob rau hauv lub interface chaw.

Nyob rau hauv thiaj li yuav xa lub raj los ntawm tshwm sim condensate, lawv yuav tsum tau kev txhawb nrog ib tug tej nqes hav, qhia ntawm lub kos-thawv siv los sau dej.

Yog hais tias muaj yog ib tug yuav tsum tau mus pw hauv cov yeeb nkab ntawm lub hauv paus ntawm lub tsev, ces qhov no yuav tsum tau ua los ntawm pw ntsiab horizontally. Tom qab cov khoom no yog lawm ua tus sau nrog ib tug daws. Yog hais tias cov khoom tsis nteg horizontally, lub load rau lawv yuav muab faib unevenly, uas muaj peev xwm ua rau puas tsuaj. Thaum pw kav ntawm ib tug tob uas yog ntau tshaj 2 m, nws yog tsim nyog los muab ntxiv tiv thaiv muaj nyob rau hauv concreting channel. Paab qhob txheej yuav tsum tsis txhob ua me me los yog loj tshaj 80-100 hli.

HDPE-khoom yog tus nqi qis, tiam sis yuav tau siab zoo yam ntxwv, nws yog tej zaum yuav siv tsis tau lawv li tsuas yog rau cov tso sewerage thiab dej mov systems, tab sis kuj yuav tiv thaiv cov cable, mounted underground. Khoom yog universal, raws li yog siv nyob rau hauv lub lwm systems, sab nraud thiab sab hauv layout, uas tso cai rau lawv mus nce ntau tis, nrog rau cov installation ntawm cua daj cua dub dej.
