Umuyoboro wa FDPE vs PE Umuyoboro: Icyo Amagambo asobanura
Umuyoboro wa PE vs HDPEni Ikibazo.PEasobanura umuryango wa polyethylene, mugiheHDPEni murwego rwo hejuru - urwego rwubucucike muri PE rusanzwe rusobanurwa kumiyoboro yumuvuduko. Muyandi magambo, "imiyoboro yumuvuduko wa PE" ikoreshwa mumazi nu miyoboro yingirakamaro mubyukuri ikozwe mubyiciro bya HDPE.
Uhereye ku masoko, icyangombwa ntabwo ari ikirango ahubwo niicyiciro cya resin hamwe nibikorwa. Kurugero, umushinga urashobora gusaba ibyiciro byihariye nkaPE4710. Niyo mpamvu kandi amagambo avuga gusa "umuyoboro wa HDPE" ashobora kuba atuzuye - abaguzi bakeneye icyiciro cya resin, SDR, hamwe nubuyobozi bugamije gusuzuma uburinganire.
Kuriyi page, ibicuruzwa ni igitutu - cyapimwe sisitemu ya HDPE / PE ihujwe nuburinganire busanzwe bwamazi nkaASTM D3035, ASTM F714, naAWWA C906. Ibipimo ngenderwaho bisobanura uburyo umuyoboro wapimwe, ukageragezwa, ugashyirwaho ikimenyetso, ukarekurwa - bityo "PE vs HDPE" ihinduka icyemezo gifatika kubyerekeyekubahiriza + igipimo cyumuvuduko + inyandiko zikurikiranwa, kuruta izina ryo kwamamaza.
PE Umuyoboro vs PPR: Uburyo bwo Guhitamo na Service
KuriPE umuyoboro vs PPR, icyemezo mubisanzwe kijyanye n'ubushyuhe bwa serivisi nuburyo bwo kwishyiriraho: Umuyoboro wumuvuduko wa PE ukunze gutoranyirizwa mumashanyarazi yo gushyingura hamwe no kwiruka hanze (fusion - bifatanije, kugenda - kwihanganira), mugihe PPR ikoreshwa cyane mukubaka sisitemu y'amazi ashyushye / akonje hamwe nuburyo butandukanye bwo guhuza hamwe nuburyo bukoreshwa (urugero, ISO 15874 ikunze gukoreshwa kuri sisitemu ya PPR). Huza ibikoresho mbere yinshingano, hanyuma wemeze guhuza hamwe no gutanga ibyemezo mbere yo gutumiza.
Umuyoboro wa HDPE ukoreshwa iki?
Imiyoboro ya HDPE ikoreshwa cyane mumiyoboro y'amazi ikandamijwe kubera ko ikomeza kwizerwa mubihe nyabyo bisanzwe bitera imyanda: kwiruka maremare maremare, guhuza karuvati - ins, hamwe nibice byerekana kugenda bito kuva gutura cyangwa gutwara imizigo. Kuri anmumahanga yo kuvugurura amakomine muma Dubai (UAE), rwiyemezamirimo yasimbuye gusazaDN200 - DN400gukwirakwiza nyamukuru kumuhanda uhuze cyane kumuhanda aho akazi kagarukiragaijoro - guhindura Windowsn'umuhanda uhamye - gufungura igihe ntarengwa. Inyungu ifatika ntabwo yari "plastike vs icyuma" mubitekerezo - nibyobuto - guhuza ingingoyagabanije imashini yamenetse mugihe cyo gupima igitutu, bityo komisiyo irashobora gutera imbere igice - na - igice utirukanye uduce duto duto kuri couple nyuma yo gusubira inyuma. Kuri ubu bwoko bwa porogaramu, Umuyoboro wa Octal mubisanzwe utanga umuyoboro nkigipapuro gisobanuwe (ingano + SDR + icyiciro cyumuvuduko) hamwe nikimenyetso gisobanutse neza, bityo urubuga QA rushobora guhuza inyandiko yikizamini cyumuvuduko nicyo cyashyizweho.
Umuyoboro wa HDPE nawo watoranijwe mugihe uburyo bwo kwishyiriraho butwara ibyemezo bifatika. Kuri anPorogaramu yambukiranya HDD hafi ya Rotterdam (Ubuholandi)kumurongo muto wohereza amazi munsi yu muyoboro, rwiyemezamirimo yari akeneye gukurura - akoresheje umugozi ufite igenzura rya OD rishobora gutegurwa kugirango umuyoboro ushobore gutambutsa imizingo no kuyobora amakadiri neza mugihe cyo gusubira inyuma, utiriwe ucyura cyangwa ngo uhatire gukora ku rwobo rwinjira. Ikipe yafunze urwego imbere nka "ingano + SDR + uburyo bwo guhuza"
Ikwirakwizwa rya gazi hamwe na serivisi ihuza (gaze - ibibazo bisanzwe byubahirizwa):
Umuyoboro wa HDPEPorogaramu igengwa nuburinganire butandukanye hamwe na logique yo kwemerwa kuruta imirongo y'amazi meza. Kuri lisansi yohereza / gukwirakwiza, ibisobanuro bikunze kuvugwaASTM D2513na / cyangwaISO 4437 / EN 1555(ukurikije akarere n'ibisabwa kubakoresha). Igenzura ryingenzi ryamasoko ni ugusubiramo no kwemeza umuyoboro nka "serivisi ya gazi" (urwego + rusanzwe + ikimenyetso + cyerekana + igipimo cy’ibizamini), aho gufata icyemezo - icyiciro cya PE gishobora gukoreshwa.
Kwambukiranya HDD / kurambirana aho hakenewe umugozi uhoraho:
Ku muyoboro wa Octal Umuyoboro wa HDD, rwiyemezamirimo yari akeneye umugozi muremure uhoraho hamwe na OD ihamye kugirango ishobore kunyura hejuru no kuyobora amakadiri neza. Iteka ryarafunzwe nk "ingano + SDR / urwego rwumuvuduko + uburyo bwo guhuza," kandi umurima QA wibanze ku bipimo byo guhuza, kugenzura amasaro, hamwe na hydrotest - aho gucunga ibice byinshi byubukanishi imbere yabyo.
Guhindura abantu amagambo 134
Kumasoko, icyangombwa nukugura umuyoboro wa HDPE nka sisitemu: kwemeza serivisi (amazi vs gaze), hanyuma ugaragazeUrutonde rwa OD / ingano, icyiciro cya SDR / icyiciro, resin urwego aho bikenewe, hamwe na fusion standard / uburyo. Iri ni ryo tandukaniro riri hagati yo gusohora neza kurubuga nakazi gahagarara kuko umuyoboro ari "PE" mwizina ariko ntuhujwe nicyiciro cyumuvuduko, uburyo bwo guhuza, cyangwa inyandiko umugenzuzi ategereje.
HDPE Umuyoboro Utanga Umurongo & Ubwishingizi Bwiza
Imiyoboro ya HDPE
Umusaruro wa umuyoboro wa HDPE utangirana no gusohora inkumi ndende - ubucucike bwa polyethylene, bugaragaza uburemere bwa bimodal molekulari mu byiciro bya PE4710 kugirango byongere ubukana no guhangana. Nyuma yo gusohora, imiyoboro ikorerwa ibizamini bya hydrostatike kuri AWWA C906 inshuro 1.5 icyiciro cyumuvuduko, hamwe nubugenzuzi bwa ultrasonic kugirango hamenyekane uburinganire bwurukuta no kumenya inenge zose. Igenzura ryuzuye ryuzuye ririmo ibintu byiza biranga (PMI), kugenzura neza ibipimo, no kugerageza guturika kugirango uburinganire bwuburinganire. Impamyabumenyi yikizamini (MTC kuri EN 10204 3.1) itanga inyandiko zirambuye zerekana ibyiciro bya resin, ibipimo byo gukuramo, hamwe n’ibisubizo bitangiza {NDT), mu gihe ubugenzuzi bwa gatatu - bwagenzuwe n’ibigo nka SGS cyangwa BV buraboneka byoroshye kugira ngo wongere ibyiringiro.
Kwakira Umwanya Mbere yo Gusubira inyuma (Kuki Hitamo Umuyoboro wa Octal)
Imishinga myinshi ya HDPE imiyoboro idatinda kuko "PE iragoye" - baratinda kuko aho bakorera ntibashobora gusubira inyuma kugeza igihe umugenzuzi ashobora gufunga urutonde rwabemerewe. Umuyoboro wa Octal ufata PE itangwa nka akurekura - biteguyeyubatswe hafi yuburyo imyobo igenda: ubufindo bwo gutanga, ibikorwa byo guhuza, hamwe na hydrotest ibice bigomba gutonda umurongo kugirango itsinda ryikibuga rishobore kwerekana ko ryubahirizwa byihuse, atari nyuma yuko umuyoboro umaze kuba mubutaka.
- Fusion - inkunga yibanze yo kwemerwa:PE imikorere ibaho hamwe. Ku mishinga ishaka kugenzura cyane, Umuyoboro wa Octal uhuza urwego rutangwa hamwe nakazi kakozwe mukwemezaguhuza uburyo (butt fusion / electrofusion), guhuza neza, hamwe nuburyo bwo kwemerwaimbere, bityo ibiti byo guhuza abakozi hamwe nindangamuntu bihuriweho bishobora gusubirwamo hashingiwe ku buryo bukwiye nta "buryo butari bwo bwo guhuza".
- Hydrotest isobanutse mbere yo kwishyiriraho:Turasunika indero yoroshye yo gutanga amasoko: gusobanuraimipaka yikizamini, fata umwanya, nibisabwakare (no kohereza mubufindo bushyigikira iyo gahunda). Ibi birinda gutinda - ibyiciro byo gusubiramo aho igice kigomba gusubirwamo - kubera ko ibikoresho na gahunda yo gukora ibizamini bitajyanye.
- Guhuza urukuta no kwizerwa:Imikorere y'igitutu ni igishushanyo - gishingiye, ariko kwizerwa kumurima biterwa no kugenzura urukuta ruhamye no gusukura. Kumiyoboro y'amazi n'imigozi ya HDD, dushimangira guhuza urukuta kugirango tugabanye ahantu hacitse intege zitunguranye.
- Ubuso hamwe no kurinda birinda ibyangiritse byihishe:Gouges hamwe no gushushanya byimbitse birashobora guhinduka ingingo zo kwangwa mbere yo gusubira inyuma. Twifashishije gupakira / kurangiza kurinda no kuyobora ubuyobozi kugirango imiyoboro igere kandi ibyiciro hamwe nibisabwa bike byangiritse no kugabanuka - hanze kurubuga.
