uchwepheshe wepayipi

Iminyaka eyi-15 Yokukhiqiza

I-China Manufacture High Pressure 4 Inch Plastic Supply PVC-M Ipayipi

Incazelo emfushane:

I-PVC-M isho ipayipi le-polyvinyl chloride eliguquliwe, elibonakala ngento uqobo ngaphansi kwengcindezi encane.


Imininingwane yomkhiqizo

Amathegi womkhiqizo

Isingeniso sezinto ezibonakalayo

Ukusebenza kokulwa nokuzamazama komhlaba kwepayipi le-PVC-M, umkhiqizo olungisiwe wemikhiqizo yepayipi le-PVC, kungcono kakhulu kunalokho kwe-PVC-U

Impilo ende ye-PVC ibhekisa kwinto uqobo uma kunengcindezi encane noma ingekho ingcindezi, impilo yayo yinde kune-PE namanye amapulasitiki, futhi amandla esikhathi eside e-PVC angaphezu noma alingana no-25Mpa, kanti i-PE100 ingaphezu noma ilingana ne-10Mpa.Kodwa i-PVC ehambelana ne-PE "ingama-brittle" kancane. Okungukuthi, umthelela kulula ukulimala, futhi amandla esikhathi eside aphansi.Ngakho-ke, ezingeni likazwelonke, i-UPVC isebenzisa into yokuphepha engu-2.5 ( ∮90 noma i-2.0 (∮110 noma ngaphezulu)) ukuklama ipayipi, kuyilapho i-PE isebenzisa kuphela into yokuphepha engu-1.2 (PE100) ukuklama ipayipi. Ngamanye amagama, inqobo nje uma i-UPVC incane, ngeke nje ithuthukise ukusebenza kokuphepha kwepayipi (into enjalo yokuphepha ayidingekile) .Ingaxazulula nokuzivumelanisa nezimo zamanje zokwakhiwa kwasekhaya.

Ukuze kube lula kubasebenzisi, sizibophezele ekuthuthukiseni ubunzima be-PVC nokunciphisa ukuphepha kokuklama.Ngasikhathi sinye vumela umsebenzisi azizwe ekhululekile ukusebenzisa ipayipi le-PVC, enze uchungechunge locwaningo. ukuqinisekisa ukuqina kobulukhuni, kwamukelwa indlela yokwanda kokuqina ngaphandle kokufaka ipulasitiki, ekugcineni ipayipi le-PVC-M lasungulwa.

Ngaphansi kwesisekelo sokunganciphisi amandla esikhathi eside, ubunzima buphakama izikhathi eziphindwe ka-5 ~ 10 kunalezo ze-UPVC futhi amandla we-notch amandla angaphezu kuka-30MPa (20 ℃), okuyizikhathi ezingaphezu kwezingu-3 ze-UPVC. ukuqina kuyathuthukiswa, ukuzwela ukwehluleka kuyehla, futhi ipayipi akulula ukulimala noma izinga lokulimala lehliswe kakhulu, ukuze ithonya emandleni esikhathi eside libe lincane. 1.6 (Kubulukhuni obungenhla, i-coefficient eqinisekiswe amazwe amaningi, ingasaphathwa eyenkomba yenkinga ye-PVC-M yenkampani yethu ingaphezu kokuqina kwayo kokuhlolwa). Yize izindleko zethoni ze-PVC-M ziphakeme kune-UPVC, intengo ngemitha ngayinye ayiphakeme kune-UPVC ngenxa yenani eliphansi le-coefficient yokuphepha nobukhulu bodonga obunciphile.

Ngale ndlela, ipayipi le-PVC-M linezinzuzo zombili i-PE pipe ne-UPVC ukufakwa nokugcinwa okulula ngasikhathi sinye, intengo ayiphakeme kunepayipi le-UPVC, cishe i-30% iphansi kunepayipi le-PE ngemitha ngalinye. amathemba abanzi kakhulu kunamaphayiphi we-UPVC ne-PE.

Umehluko phakathi kwe-

Uhlelo lwe-PVC PVC piping luneminyaka ecishe ibe ngu-70 yomlando wokuthuthuka, ngenxa yamamoduli aphezulu, amandla aphezulu nentengo ephansi kube ukusetshenziswa okukhulu kakhulu kwepayipi lepayipi lepulasitiki. kuthuthuke kakhulu futhi izinga lokukhula kwamanye amazwe nezindawo zokufaka izicelo zehlile.

Yize uhlelo lwepayipi le-PVC laseChina selukhiqize ukukhishwa kwaminyaka yonke okungaphezu kwamathani ayisigidi ayi-1 wesikali esikhulu, kepha belilokhu lihlala ebangeni lendabuko le-PVC-U, amabhizinisi amaningi awaqondi mkhuba kanye nenqubekela phambili yobuchwepheshe bamapayipi we-PVC wamazwe omhlaba, ngoba inqubekelaphambili yezobuchwepheshe iyephuza ukukhawulela ukuqhubekiswa okuqhubekayo nokusetshenziswa.

Umhlaba uhlola njalo ukwenza ngcono izinga lokusebenza kohlelo lwamapayipi e-PVC futhi unwebise inkambu yesicelo sohlelo lwamapayipi e-PVC, futhi wenze impumelelo emangalisayo kule minyaka eyishumi edlule.

- Thuthukisa ukuqina ngokuguqulwa, uthuthukise uhlelo lwepayipi le-PVC eliguquliwe elinokumelana okuhle nomthelela wokuqhekeka ngenkathi ugcina amandla aphakeme, aziwa kakhulu nge-PVC-M noma i-PVC-A noma i-PVC-HI.

- Ngokunwebeka okuvela kumabhidi amabili ngenkathi kucutshungulwa ipayipi, ukuma kwamangqamuzana kungathuthukisa kakhulu amandla nobulukhuni.Kuvame ukubizwa nge-PVC-O noma i-BO-PVC.

- Ukunwetshwa kwezicelo, okufana: nokwenza ngcono ukuguqulwa kwepayipi le-PVC kungagotshwa, kusongwe, futhi kufakwe insimbi.

Ushintsho nentuthuko yesimo samazwe omhlaba eminyakeni yamuva kunikeze ithuba elingakaze libonwe lomlando lokwakhiwa kohlelo lwamapayipi e-PVC eChina. Izinhlelo zamapayipi wePolyolefin, ancintisana nezinhlelo zamapayipi e-PVC ezinhlelweni eziningi, zithinteke kakhulu ngokuqhuma kwentengo kawoyela. , ngenkathi i-PVC, engasetshenziswa njengempahla eluhlaza yamalahle, ithole ukuncintisana ngokuhlala ngamanani aphansi.Ukubhekana namathuba amasha emakethe, uma sikwazi ukusheshisa izinto ezintsha nentuthuko, ukuhambisana nejubane lenqubekela phambili yobuchwepheshe yamazwe omhlaba ngohlelo lwe-PVC piping, singavula isimo esisha.

Amapayipi axhunywe kanjani

Ifomu lokuxhuma lepayipi le-PVC-M ngokuyisisekelo liyefana nelale-PVC-U ejwayelekile, futhi ngokuvamile kunezindlela ezimbili zokuxhuma:

1. Amapayipi amancane we-calibre ahlanganiswe ngokunamathela;

2. Amapayipi amakhulu wobubanzi axhunywe ngezindandatho zenjoloba;

Lapho amapayipi e-PVC-M exhunywe ngamapayipi nemishini yezinye izinto, ama-flanges nemicu ingasetshenziswa ukuwaxhuma.Amafomu wokuxhuma angenhla alula ukuxhuma, aphephile futhi athembekile.
