isicelo

I-PVC-o, igama lesiTshayina elithi biaxial oriented polyvinyl chloride, luhlobo olutsha lokuzivelela kombhobho wePVC, ngokusebenzisa itekhnoloji yokulungelelanisa eyodwa yokwenza umbhobho, umbhobho we-PVC-U oveliswa ngendlela ye-extrusion yoluliwe nge-axially kunye ne-circumferentially, ukuze PVC iimolekyuli chain elide kumbhobho kulungiselelo biaxial.Umbhobho omtsha wePVC onamandla amakhulu, ukuqina okuphezulu, impembelelo ephezulu kunye nokumelana nokudinwa kwafunyanwa.

Igama lesiTshayina: i-biaxial orientation polyvinyl chloride

Igama lolwimi lwangaphandle: PVC-O

Isicelo: Ukubonelela ngamanzi kunye nobunjineli bokuhambisa amanzi

Inkampani yokuqala: Uponor UK

Wavela: ngowe-1970

Imbali yoPhuhliso

I-PVC-O yaqala ukuphuhliswa yiYorkshirelmperial Plastics (Uponor) e-UK ngo-1970 kwaye sele iveliswe nguMolecor, Wawin kunye nabanye.Kwinqanaba lokuqala, inkqubo yokucubungula "i-off-line" (indlela yokucubungula amanyathelo amabini) yamkelwa, apho i-extrusion yenziwe kwaye ipholile icandelo lombhobho we-PVC-U (i-embryo engqingqwa) yandiswa ukuya kubukhulu obufunekayo kwi-mold ngokufudumeza. kunye noxinzelelo ekuqondeni ukuziqhelanisa.Uphando lovavanyo kunye nokusetyenziswa okusebenzayo kubonisa ukuba i-PVC-O inomsebenzi ongaqhelekanga, kodwa inkqubo yokucubungula "ngaphandle kwe-intanethi" inesantya esisezantsi sokuvelisa kunye nokutyalomali oluphezulu lwezixhobo, kwaye kunzima ukuvakalisa.Kamva iphuhliswe kwinkqubo ye-extrusion "in-line" yokuqhelaniswa, ukuveliswa okuqhubekayo kwePVC-O.Inkqubo yemveliso yindlela yokucwangcisa inyathelo elinye, oko kukuthi, kumgca wokukhupha umbhobho, umbhobho we-PVC-U (i-embryo yezinto ezityebileyo) iye yakhutshelwa ukufezekisa ukuqhelaniswa kwe-biaxial ngokwandisa umsesane kunye nokwelula kwe-axial, kwaye emva koko ukupholisa kunye nokubumba. kumbhobho wePVC-O.Inkqubo yokuveliswa kwe-biaxial orientation "in-line" iphucula kakhulu ukusebenza kakuhle kwemveliso, ukunciphisa iindleko zokuvelisa kunye nokwandisa ukukhuphisana kwe-PVC-O kunye neminye imibhobho.Ngo-2014, i-Baoplastic Pipe, ishishini lasekhaya, yakhokela ekuphuhliseni itekhnoloji yokuvelisa inyathelo elinye eyomileyo, ethe yaqhawula ulawulo lwetekhnoloji yamashishini angaphandle.

I-tubing ye-PVC-O isetyenziswe e-UK, eFransi, e-Holland, ePortugal, e-USA, e-Australia, eMzantsi Afrika nase-Japan iminyaka emininzi.I-United States, i-Australia kunye namanye amazwe apapashe umgangatho wemveliso we-PVC-O, kunye noMbutho weMigangatho yamazwe ngamazwe upapashe umgangatho we-PVC-O -ISO 16422-2014.Umgangatho wesizwe waseTshayina othi “Oriented Polyvinyl chloride (PVC-O) Pipe and Fittings for Pressure Water Transportation” GB/T41422-2022 nayo yabhengezwa ngoAprili 15, 2022, yaza yaphunyezwa ngokusemthethweni nge-1 kaNovemba ka-2022.

Ngenxa yokuba umbhobho we-PVC-O u-axial kunye nokwelula okujikelezayo kombhobho wokuqala wePVC-U owenziweyo, ubukhulu bodonga lombhobho bubhityile.Xa kuthelekiswa nombhobho wonikezelo lwamanzi we-PVC-U, ubukhulu bodonga lwe-PVC-O yombhobho wokuhambisa amanzi bunokuncitshiswa ngama-35% -40%, okusindisa kakhulu izinto kunye nokunciphisa iindleko.Kwangaxeshanye, ngenxa yokuqhelaniswa neemolekyuli zetsheyini ezinde zombhobho wePVC-U ovelisiweyo, ububanzi bombhobho buyanda ekusetyenzweni, okwenza ukuqhelaniswa nemolekyuli kwicala leringi kwaye kuzise uphuculo olukhulu kumandla kunye nokuqina. kwezi mpawu zimbini.Ukuqhelaniswa kweeamolekyu kwandisa kakhulu amandla amafutshane kunye nexesha elide lezinto eziphathekayo.Ngenxa yamandla abalaseleyo kunye nokuqina, iminyaka engama-50 yokhuseleko lwezinto eziphathekayo ze-PVC-O ze-MRS45 kunye ne-MRS50 zingabonakaliswa njenge-1.6 okanye i-1.4, ngoko ke uxinzelelo loyilo lombhobho we-PVC-O lunokufikelela kwi-28MPa kunye ne-32MPa.Isakhiwo se-lamellar esiveliswa yi-molecular orientation processing sisitshixo sokuqina okuphezulu kwe-PVC-O.Ukuba ukuqhekeka kwenzeka ngenxa yeziphene kunye nemithwalo yamanqaku, ulwakhiwo olunqamlekileyo luya kuthintela ukuqhekeka ukuba kudlule kwizinto eziphathekayo, kwaye ukusabalalisa kwe-crack kuthintelwe ngokufanelekileyo ngokunciphisa uxinzelelo loxinzelelo njengoko ukuqhekeka kudlula kwiileyile.Olunye uhlobo olutsha lombhobho - umbhobho we-PVC-M oguqukileyo oguquliweyo, nangona amandla ayo empembelelo aphuculwe, kodwa amandla okuqina awaphuculwanga.

Ummandla weSicelo

Kumazwe angaphandle, iPVC-O isetyenziswa ikakhulu kwimibhobho yonikezelo lwamanzi, umbhobho womgodi, umbhobho wokubeka kunye nokulungisa umbhobho, uthungelwano lwemibhobho yegesi kunye nezinye iindawo.Amanye amazwe kuthungelwano lombhobho wamanzi okusela kwisicelo se-PVC-O siyanda ngokuthe ngcembe, sithatha indawo ye-PVC-U, ngokutsho kwengxelo yophando ye-Wavin Group, eNetherlands, eFransi, eSpeyin, eMntla Melika, eMzantsi Melika, eOstreliya kunye ne-PVC. amanye amazwe kubuninzi bokusetyenziswa kwemibhobho yePVC-O.Inethiwekhi yombhobho wamanzi okusela eNetherlands ine-100% yokusetyenziswa kombhobho wePVC-O, iFransi kunye namanye amazwe kwiminyaka emibini esondeleyo iya kwamkelwa yonke.Isetyenziswe kakhulu kunikezelo lwamanzi ezidolophini, amanzi okusela asemaphandleni, ukunkcenkceshela okonga amanzi kunye nokuhamba kwamanzi amdaka kunye namanye amasimi.Indawo yasemgodini inzima kakhulu kwaye iimfuno zokhuseleko zingqongqo.Kwimekobume engaphantsi komhlaba enomhlwa, umbhobho wePVC-O onamandla amakhulu, ukuqina okuphezulu, ukuchasana nempembelelo kunye nokungakhuseli kunenzuzo yokhuphiswano kakhulu.

Iinzuzo zoqoqosho kutyalo-mali kwishishini le-PVC-O

Iqela leWavin eNetherlands livelise kwaye lasebenzisa umbhobho wePVC-O iminyaka emininzi.Ngokwezibalo zeQela leWavin, xa kuthelekiswa nePVC-U, utyalo-mali lombhobho wePVC-O kunye nenkcitho zezi zilandelayo:

(1) Umyinge wokongiwa kwemathiriyeli ekrwada yi-11.58%.

(2) 2.5-3 amaxesha ngaphezulu PVC-O utyalo-mali (eYurophu).

(3) Isivuno si-300-650 kg / h, kwaye ubude bunyuswe ngama-20% -40%.

(4) Izinga lokukhatywa linyuka nge-2% -4%.

(5) Ukwandisa ukusetyenziswa kwamandla ngama-25%.

(6) I-10% -15% ukunyuka kweendleko zokusebenza kwabasebenzi.

(7) Ubude bomgca wemveliso buya kwandiswa ngama-25%.

Ngokubala ngokubanzi, utyalo-mali lwepayipi ye-1 m lungancitshiswa ngo-33% -44%, kwaye ixabiso linganyuswa nge-10% -15%.Okubonakalayo, umbhobho wePVC-O utyalo-mali lwexesha elinye, umvuzo wobomi bonke.

Okwangoku, iinkampani zasekhaya zePlasitiki zeBao nazo zibonelela ngodluliselo lwetekhnoloji kunye neenkonzo kwishishini elifanayo, elithe lafikelelwa kuquka iSichuan Yibin Tianyuan, iBrazil Cole kunye namanye amashishini amakhulu okulungisa iplastiki.

Ithemba loPhuhliso

Utshintsho kunye nophuhliso lwemeko yamazwe ngamazwe lunikeza ithuba lembali elingazange libonwe ngaphambili kuphuhliso lwenkqubo yombhobho wePVC kwilizwe lethu.Iinkqubo zemibhobho ye-Polyhydrocarbon, ezikhuphisana neenkqubo zemibhobho ye-PVC kwizicelo ezininzi ngenxa yexabiso eliphakamileyo leoli, liye lachaphazeleka kakhulu, ngelixa i-PVC esekelwe kumalahle iye yandisa ukukhuphisana kwayo ngokugcina amaxabiso aphantsi.

Inkqubo yemibhobho ye-PVC ineminyaka ephantse ibe yi-70 yembali yophuhliso, ngenxa yemodyuli yayo ephezulu, amandla aphezulu kunye neenzuzo zexabiso eliphantsi, ngoko ibe yeyona nto isetyenziswa kakhulu kwihlabathi lenkqubo yemibhobho yeplastiki, isetyenziswe ngokubanzi kwiinkalo ezininzi kuluntu lwanamhlanje.Ngophuhliso olukhawulezayo loshishino lwemibhobho yeplastiki yaseTshayina, iye yaba lelinye lamazwe amakhulu okuvelisa kunye nokusetyenziswa kwemibhobho yeplastiki kwihlabathi.Umthamo wemveliso wePVC PIPE kwilizwe lethu ungaphezu kwezigidi ezi-2 ze-t / a, kuphela i-akhawunti malunga ne-50% yexabiso lilonke lombhobho weplastiki, ngelixa kumazwe aphuhlileyo, ukusetyenziswa kombhobho we-PVC ngokuqhelekileyo kubalela i-70% -80% kwimarike yemibhobho yeplastiki.

Ngenkulungwane yama-21, umbhobho we-PVC ujongene nabakhuphisana abaninzi, ngakumbi ngenxa yokuphuculwa okucacileyo kweepropathi ze-resin ezifana ne-HDPE (efana ne-PE63 ukuya kwi-PE80 kunye ne-PE100), umbhobho we-PE unobulukhuni obubalaseleyo kunye nokumelana nefuthe lehamile yamanzi.Ukongezelela, ukugxekwa kweklorini yimibutho yokukhusela indalo kumazwe ahlukeneyo kwenza iipayipi zePVC zijongene nesimo esinzima.Nangona kunjalo, bekungahoywa ixesha elide ukuba imibhobho yePVC inokuthintela ukungena kwezinye izinto ezinobuthi kunye neziyingozi ezingcono kunemibhobho ye-PE.Kwixesha elizayo lemarike yombhobho wehlabathi kwindawo ephambili okanye umbhobho wePVC, esona sizathu sisisiseko sisekutsha kweteknoloji, inkqubela phambili yetekhnoloji.Ukusetyenziswa kobugcisa obutsha bePVC resin kunye nombhobho wePVC, ngakumbi ukusungulwa kobuchwepheshe bokulungiswa kombhobho wePVC kunye nenkqubo, kuye kwaphucula kakhulu uqoqosho lwePVC yombhobho kwaye kwavula amasimi amatsha esicelo.
