Pvc-o, izina ryigishinwa biaxial yerekanwe na polyvinyl chloride, nuburyo bushya bwubwihindurize bwumuyoboro wa PVC, binyuze mubuhanga bwihariye bwo gutunganya icyerekezo cyo gukora umuyoboro, umuyoboro wa PVC-U ukorwa nuburyo bwo gukuramo urambuye mu buryo bwuzuye kandi buzengurutse, ku buryo the PVC ndende ya molekile ndende mumiyoboro muburyo bwa biaxial.Habonetse umuyoboro mushya wa PVC ufite imbaraga nyinshi, ubukana bwinshi, ingaruka nyinshi no kurwanya umunaniro.

Izina ry'igishinwa: icyerekezo cya biaxial polyvinyl chloride

Izina ry'ururimi rw'amahanga: PVC-O

Gusaba: Gutanga amazi no gutunganya amazi

Isosiyete y'umwimerere: Onor UK

Yagaragaye: 1970

Amateka y'Iterambere

PVC-O yatunganijwe bwa mbere na Yorkshirelmperial Plastics (Onor) mu Bwongereza mu 1970 kandi kuva icyo gihe yakozwe na Molecor, Wawin n'abandi.Mugihe cyambere, hashyizweho uburyo bwo gutunganya "off-line" (uburyo bwo gutunganya intambwe ebyiri), aho gukuramo byakozwe no gukonjesha igice cyumuyoboro wa PVC-U (urusoro rwinshi) rwaguwe kugeza mubunini busabwa mubibumbano hashyushye no guhatira kumenya icyerekezo.Ubushakashatsi bwakozwe nubushakashatsi bufatika bwerekana ko PVC-O ifite imikorere idasanzwe, ariko inzira yo gutunganya "kumurongo" ifite umuvuduko muke wumusaruro hamwe nishoramari ryibikoresho byinshi, kandi biragoye kubyamamaza.Nyuma yaje gutezimbere mugikorwa cyo gukuramo "kumurongo" icyerekezo, umusaruro uhoraho wa PVC-O.Uburyo bwo kubyaza umusaruro nuburyo bumwe bwo gutunganya inzira, ni ukuvuga, mumurongo wo kuvoma imiyoboro, umuyoboro wa PVC-U (urusoro rwibintu byuzuye) wasohotse kugirango ugere ku cyerekezo cya biaxial binyuze mu kwagura impeta no kurambura axial, hanyuma gukonjesha no gushiraho mu muyoboro wa PVC-O."In-line" biaxial icyerekezo cyibikorwa byongera umusaruro cyane, bigabanya ibiciro byinganda kandi bizamura irushanwa rya PVC-O nindi miyoboro.Mu mwaka wa 2014, Baoplastic Pipe, uruganda rwo mu gihugu, yafashe iya mbere mu guteza imbere ikoranabuhanga ryumye ku murongo umwe w’ikoranabuhanga ribyara umusaruro, ryangiza monopoliya y’ikoranabuhanga mu bigo by’amahanga.

Imiyoboro ya PVC-O yakoreshejwe mu Bwongereza, Ubufaransa, Ubuholandi, Porutugali, Amerika, Ositaraliya, Afurika y'Epfo n'Ubuyapani imyaka myinshi.Amerika, Ositaraliya ndetse n’ibindi bihugu byashyize ahagaragara ibipimo ngenderwaho by’ibicuruzwa bya PVC-O, kandi Umuryango mpuzamahanga w’ubuziranenge nawo washyize ahagaragara PVC-O bisanzwe -ISO 16422-2014.Igipimo cy’igihugu cy’Ubushinwa “Icyerekezo cya Polyvinyl chloride (PVC-O) Umuyoboro n’ibikoresho byo gutwara amazi y’umuvuduko” GB / T41422-2022 na byo byatangajwe ku ya 15 Mata 2022, bishyirwa mu bikorwa ku mugaragaro ku ya 1 Ugushyingo 2022.

Kuberako umuyoboro wa PVC-O urambuye kandi uzengurutsa umuyoboro wambere wakozwe na PVC-U, uburebure bwurukuta rwumuyoboro ni muto.Ugereranije n'umuyoboro w'amazi wa PVC-U, uburebure bw'urukuta rw'umuyoboro w'amazi wa PVC-O urashobora kugabanukaho 35% -40%, bikiza cyane ibikoresho kandi bikagabanya igiciro.Muri icyo gihe, bitewe nicyerekezo cya molekile ndende yumuyoboro wa PVC-U yakozwe, diameter yumuyoboro yiyongera mugutunganya, bigatuma icyerekezo cya molekile cyerekezo cyimpeta kandi kizana iterambere ryinshi mumbaraga no gukomera. Bya Ibintu Byumubiri.Icyerekezo cya molekile cyongera cyane imbaraga ngufi - nigihe kirekire cyibikoresho.Bitewe n'imbaraga zidasanzwe no gukomera, ibintu byimyaka 50 byumutekano wibikoresho bya PVC-O bya MRS45 na MRS50 birashobora kugaragazwa nka 1.6 cyangwa 1.4, bityo guhangayikishwa nigishushanyo cyumuyoboro wa PVC-O gishobora kugera kuri 28MPa na 32MPa.Imiterere ya lamellar yakozwe na molekulari yerekana gutunganya ni urufunguzo rwo gukomera kwa PVC-O.Niba ibisebe bibaye kubera inenge hamwe nu mutwaro uremereye, imiterere itondekanye izarinda gucamo kunyura mu bikoresho, kandi ikwirakwizwa ry’imitsi rihagarikwa neza no kugabanya imihangayiko yo kugabanuka nkuko igikoma kinyura mu byiciro.Ubundi bwoko bushya bwumuyoboro - wahinduwe cyane umuyoboro wa PVC-M, nubwo imbaraga zawo zateye imbere, ariko imbaraga za tensile ntizitezimbere.

Umwanya wo gusaba

Mu bihugu by'amahanga, PVC-O ikoreshwa cyane cyane mu miyoboro itanga amazi, umuyoboro w'amabuye y'agaciro, gushyiramo umwobo no gusana umuyoboro, umuyoboro wa gazi n'indi mirima.Raporo y’ubushakashatsi bwakozwe na Wavin, Ubuholandi, Ubufaransa, Espagne, Amerika y'Amajyaruguru, Amerika y'Epfo, Ositaraliya na bindi bihugu biri mubwinshi bwo gukoresha imiyoboro ya PVC-O.Umuyoboro w’amazi yo kunywa mu Buholandi ukoresha 100% umuyoboro wa PVC-O, Ubufaransa n’ibindi bihugu mu myaka ibiri iri hafi yose bizemerwa.Yakoreshejwe cyane mu gutanga amazi yo mu mijyi, amazi yo mu cyaro, kuhira amazi azigama no kuvoma imyanda n'indi mirima.Ibidukikije bya kirombe birakaze cyane kandi ibyangombwa byumutekano birakomeye.Mubidukikije byangirika, umuyoboro wa PVC-O ufite imbaraga nyinshi, ubukana bwinshi, kurwanya ingaruka no kutangirika bifite inyungu zo guhatanira cyane.

Inyungu zubukungu zo gushora mubikorwa bya PVC-O

Itsinda rya Wavin mu Buholandi ryakoze kandi rikoresha umuyoboro wa PVC-O imyaka myinshi.Dukurikije imibare ya Wavin Group, ugereranije na PVC-U, ishoramari rya PVC-O n’imikoreshereze ni ibi bikurikira:

(1) Ikigereranyo cyo kuzigama ibikoresho fatizo ni 11.58%.

(2) Inshuro 2,5-3 zirenga PVC-O ishoramari (i Burayi).

(3) Umusaruro ni 300-650 kg / h, kandi uburebure bwiyongereyeho 20% -40%.

(4) Igipimo cyo kwangwa cyiyongeraho 2% -4%.

(5) Ongera gukoresha ingufu za 25%.

(6) 10% -15% kwiyongera mubiciro byabakozi.

(7) Uburebure bwumurongo wibyakozwe buzongerwaho 25%.

Kubara byuzuye, ishoramari ryumuyoboro wa m 1 rishobora kugabanukaho 33% -44%, kandi igiciro gishobora kwiyongera 10% -15%.Ikigaragara, umuyoboro wa PVC-O ni ishoramari rimwe, amafaranga yinjiza.

Kugeza ubu, uruganda rukora imiyoboro ya pulasitike ya Bao mu gihugu narwo rutanga ihererekanyabubasha na serivisi mu nganda zimwe, zimaze kugerwaho harimo Sichuan Yibin Tianyuan, Burezili Cole n’indi mishinga minini itunganya plastike.

Icyizere cy'iterambere

Guhindura no guteza imbere imiterere mpuzamahanga bitanga amahirwe atigeze abaho mumateka yo guteza imbere imiyoboro ya PVC mugihugu cyacu.Sisitemu yo kuvoma polyhydrocarubone, ihanganye na sisitemu yo kuvoma PVC mubisabwa byinshi kubera igiciro cyinshi cya peteroli, yibasiwe cyane, mugihe PVC ishingiye ku makara yongereye ubushobozi bwo guhangana n’ibiciro biri hasi.

Sisitemu yo kuvoma PVC ifite imyaka igera kuri 70 yamateka yiterambere, kubera modulus nyinshi, imbaraga nyinshi hamwe nibiciro biri hasi, bityo rero niyo yabaye isi ikoreshwa cyane muburyo bwo gukoresha imiyoboro ya pulasitike, yakoreshejwe cyane mubice byinshi muri societe igezweho.Iterambere ryihuse ry’inganda zikoresha imiyoboro ya pulasitike mu Bushinwa, ryabaye kimwe mu bihugu binini by’imiyoboro ya pulasitiki ikoreshwa kandi ikoreshwa ku isi.Ubushobozi bwo kubyaza umusaruro PVC PIPE mu gihugu cyacu burenga miliyoni 2 t / a, gusa bingana na 50% byamafaranga yose y’umuyoboro wa pulasitike, mu gihe mu bihugu byateye imbere, ikoreshwa ry’umuyoboro wa PVC muri rusange rifite 70% -80% isoko rya plastike.

Mu kinyejana cya 21, umuyoboro wa PVC uhura nabanywanyi benshi, cyane cyane kubera iterambere ryagaragaye ryimiterere ya resin nka HDPE (nka PE63 kugeza PE80 na PE100), umuyoboro wa PE ufite ubukana buhebuje hamwe n’ingaruka zo kurwanya inyundo.Byongeye kandi, kunenga chlorine n’imiryango ishinzwe kurengera ibidukikije mu bihugu bitandukanye bituma imiyoboro ya PVC ihura n’ikibazo gikomeye.Nyamara, birengagijwe kuva kera ko imiyoboro ya PVC ishobora kubuza kwinjira mubintu bimwe na bimwe byangiza kandi byangiza kurusha imiyoboro ya PE.Mugihe kizaza cyisoko ryisi yose mumwanya wiganje cyangwa umuyoboro wa PVC, impamvu yibanze iri muburyo bushya bwikoranabuhanga, iterambere ryikoranabuhanga.Gukoresha ikoranabuhanga rishya rya PVC resin hamwe nu muyoboro wa PVC, cyane cyane guhanga udushya twa tekinoroji ya PVC itunganya no gutunganya inzira, byazamuye cyane ubukungu bwumuyoboro wa PVC kandi bifungura imirima mishya ikoreshwa.
