Nhoroondo Yebudiriro

PVC-O yakatanga kugadzirwa neYorkshirelmperial Plastics (Uponor) muUK muna 1970 uye yakabva yagadzirwa naMolecor, Wawin nevamwe.Muchikamu chekutanga, "off-line" processing process (matanho-maviri ekugadzirisa nzira) yakagamuchirwa, umo iyo extrusion yakaumbwa uye yakatonhodzwa PVC-U pipe segment (thick embryo) yakawedzerwa kusvika kuhukuru hunodiwa muhutu nekupisa. uye kumanikidzira kuti uone kutariswa.Tsvagiridzo yekuyedza uye mashandiro anoshanda anoratidza kuti PVC-O ine mashandiro anoshamisa, asi iyo "isina-line" yekugadzirisa ine yakaderera kukurumidza kugadzirwa uye yakakwirira michina yekudyara, uye zvinonetsa kuita mukurumbira.Gare gare yakagadziridzwa muiyo extrusion process "in-line" kutaridzika, inoenderera kugadzirwa kwePVC-O.Iyo nzira yekugadzira inzira imwe-nhanho yekugadzirisa nzira, ndiko kuti, mumutsetse wepombi extrusion, iyo PVC-U pombi (yakakora zvinhu embryo) yakasimudzwa kuti iwane biaxial orientation kuburikidza nekuwedzera mhete uye axial kutambanudza, uyezve kutonhora nekuumbwa. muPVC-O pombi.Iyo "in-line" biaxial orientation yekugadzira maitiro inovandudza zvakanyanya kugadzirwa, inoderedza mutengo wekugadzira uye inosimudzira kukwikwidza kwePVC-O nemamwe mapaipi.Muna 2014, Baoplastic Pipe, bhizinesi remumba, rakatungamira mukugadzira iyo yakaoma pa-line-danho rekugadzira tekinoroji, iyo yakatyora tekinoroji yemabhizinesi ekunze.

PVC-O tubing yakashandiswa muUK, France, Holland, Portugal, USA, Australia, South Africa neJapan kwemakore mazhinji.United States, Australia nedzimwe nyika dzakaburitsa chiyero chechigadzirwa chePVC-O, uye International Standards Organisation yakaburitsawo PVC-O standard -ISO 16422-2014.Chiyero chenyika cheChina "Oriented Polyvinyl chloride (PVC-O) Pipe uye Fittings for Pressure Water Transportation" GB/T41422-2022 yakaziviswa zvakare muna Kubvumbi 15, 2022, uye yakaitwa zviri pamutemo munaNovember 1, 2022.

Nekuti iyo PVC-O pombi ndeye axial uye circumferential yakatambanudzwa yepakutanga yakaumbwa PVC-U pombi, ukobvu hwemadziro hwepombi hutete.Kuenzaniswa nePVC-U pombi yemvura yekupa mvura, kukora kwemadziro ePVC-O pombi yekupa mvura inogona kuderedzwa ne35% -40%, iyo inoponesa zvakanyanya zvinhu uye inoderedza mutengo.Panguva imwecheteyo, nekuda kwekutarisa kwemamorekuru echeni refu yepombi yePVC-U inogadzirwa, dhayamita yepombi inowedzera mukugadziriswa, izvo zvinoita kuti mamolecular atarise munzira yemhete uye anounza kuvandudzwa kwakanyanya musimba uye kuoma. zvezvinhu zviviri zvemuviri.Iko kutaridzika kwemamorekuru kunowedzera zvakanyanya kupfupi - uye kwenguva refu simba rezvinhu.Nekuda kwesimba rakatanhamara uye kuomarara, makore makumi mashanu ekuchengetedza chinhu chePVC-O zvinhu zveMRS45 neMRS50 zvinogona kuratidzwa se 1.6 kana 1.4, saka dhizaini yedhizaini yePVC-O pombi inogona kusvika ku28MPa uye 32MPa.Iyo lamellar chimiro chinogadzirwa nema molecular orientation process ndiyo kiyi yekuoma kwePVC-O.Kana kutsemuka kuchiitika nekuda kwekuremara uye kuremerwa kwemapoint, iyo yakaturikidzana chimiro inodzivirira mutswe kuti upfuure nepakati pezvinhu, uye kupararira kwekuputika kunodzivirirwa zvinobudirira nekudzikisira kushushikana kwekushushikana sezvo mutswe uchipfuura nepakati.Imwe mhando nyowani yepombi - yakaomeswa yakagadziridzwa PVC-M pombi, kunyangwe simba rayo rekuita richivandudzwa, asi simba rekusimba harina kuvandudzwa.

Munda Wekushandisa

Munyika dzekunze, PVC-O inonyanya kushandiswa mupombi yemvura, pombi yemugodhi, yekuisa trenchless uye kugadzirisa pombi, gasi pombi network nemimwe minda.Dzimwe nyika dziri mupombi yemvura yekunwa network mukushandiswa kwePVC-O iri kuwedzera zvishoma nezvishoma, ichiva chinotsiva PVC-U, maererano neWavin Group ongororo mushumo, Netherlands, France, Spain, North America, South America, Australia uye dzimwe nyika dziri muhuwandu hwePVC-O pombi kushandiswa.Iyo pombi yemvura yekunwa network muNetherlands ine 100% kushandiswa kwePVC-O pombi, France nedzimwe nyika mumakore maviri ari pedyo zvichagamuchirwa.Yakave ichishandiswa zvakanyanya mukugovera mvura yemumaguta, mvura yekunwa yekumaruwa, madiridziro anochengetedza mvura uye madhiraini esuweji nemimwe minda.Mamiriro emugodhi akanyanya kuomarara uye zvinodiwa zvekuchengetedza zvakanyanya kuomarara.Munzvimbo inoora yepasi pevhu, pombi yePVC-O ine simba rakanyanya, kusimba kwepamusoro, kupikisa kwemaitiro uye kusaita ngura ine mukana wekukwikwidza.

Economic mabhenefiti ekudyara muPVC-O indasitiri

Wavin Group muNetherlands yakagadzira uye yakashandisa PVC-O pombi kwemakore mazhinji.Zvinoenderana neWavin Group nhamba, zvichienzaniswa nePVC-U, PVC-O pombi yekudyara uye mashandisiro akaita seanotevera:

(1) Avhareji yekuchengetedza kwezvinhu zvakabikwa ndeye 11.58%.

(2) 2.5-3 nguva yakawanda PVC-O mari (muEurope).

(3) Chibereko chacho 300-650 kg / h, uye urefu hunowedzerwa ne20% -40%.

(4) Chiyero chekuramba chinowedzera ne2% -4%.

(5) Wedzera kushandiswa kwesimba ne25%.

(6) 10% -15% kuwedzera kwemari yekushanda kwevashandi.

(7) Kureba kwemutsara wekugadzira kuchawedzerwa ne25%.

Nekuverenga kwakazara, mari ye1 m pombi inogona kuderedzwa ne33% -44%, uye mutengo unogona kuwedzerwa ne10% -15%.Inooneka, PVC-O pombi inguva imwe chete yekudyara, mari yeupenyu hwose.

Parizvino, makambani epamba eBao epurasitiki pombi ari kupawo tekinoroji yekufambisa uye masevhisi kuindasitiri imwe chete, iyo yakasvikwa inosanganisira Sichuan Yibin Tianyuan, Brazil Cole uye mamwe mabhizinesi makuru ekugadzira epurasitiki.

Tarisiro Yebudiriro

Shanduko uye kusimudzira kwemamiriro epasirese kunopa mukana usina kumboitika wenhoroondo yekuvandudzwa kwePVC pombi system munyika yedu.Polyhydrocarbon pombi masisitimu, ayo anokwikwidza nePVC pombi masisitimu mune akawanda maapplication nekuda kwekukwira kwemutengo wemafuta, yakakanganiswa zvakanyanya, nepo marasha-based PVC yakawedzera kukwikwidza kwayo nekuchengetedza mitengo yakaderera.

PVC piping system ine makore angangoita 70 enhoroondo yebudiriro, nekuda kweiyo yakakwirira modulus, simba rakakwirira uye yakaderera mutengo zvakanakira, saka kwave kuri kushandiswa kukuru pasi rose kwepurasitiki pombi system, yakashandiswa zvakanyanya muminda yakawanda munharaunda yemazuva ano.Nekukurumidza kusimudzira kweChinese pombi yepurasitiki indasitiri, yave imwe yenyika huru dzekugadzirwa kwepombi yepurasitiki uye kushandiswa munyika.Kusimba kwekugadzira kwePVC PIPE munyika yedu kunodarika mamirioni maviri t/a, inongoverengera inosvika makumi mashanu muzana ehuwandu hwepombi yepurasitiki, nepo munyika dzakabudirira, kushandiswa kwepombi yePVC kunowanzoita 70% -80% yemusika wepombi dzepurasitiki.

Muzana ramakore rechi21, pombi yePVC inotarisana nevakwikwidzi vakawanda, kunyanya nekuda kwekuvandudzwa kuri pachena kwezvivakwa zveresin zvakaita seHDPE (senge PE63 kusvika PE80 uye PE100), pombi yePE ine kusimba kwakanyanya uye kusamira kwesando yemvura.Mukuwedzera, kushoropodzwa kweklorini nemasangano ekuchengetedza zvakatipoteredza munyika dzakasiyana-siyana kunoita kuti mapaipi ePVC atarisana nemamiriro ezvinhu akaoma.Zvisinei, yave ichiregeredzwa kwenguva yakareba kuti mapaipi ePVC anogona kudzivirira kupinda kwezvimwe zvinhu zvine chepfu uye zvinokuvadza zviri nani pane mapaipi ePE.Mune ramangwana remusika wepasi rose pombi mune inotonga chinzvimbo kana PVC pombi, chikonzero chakakosha chiri muhunyanzvi hwekuvandudza tekinoroji, kufambira mberi kwetekinoroji.Kushandiswa kwehunyanzvi hwekugadzira tekinoroji yePVC resin uye pombi yePVC, kunyanya kuvandudzwa kwePVC pombi yekugadzirisa tekinoroji uye maitiro, yakavandudza zvakanyanya hupfumi hwePVC pombi uye yakavhura minda mitsva yekushandisa.
