izindaba

Nakuba i-HDPE double-wall bellows kanye ne-PVC double-wall bellows ibizwa ngokuthi i-double-wall bellows, kodwa ngaphezu kokubonakala kokufana okuncane, ezindaweni eziningi kuhluke kakhulu, uma ungakukholwa, bheka nje uchungechunge oluncane ukuze ukwazi ukuklelisa lezi ezihlukene ngalo.

I. UPVC izimbongolo ezikabili

I-UPVC enezindonga eziphindwe kabili, eyaziwa nangokuthi i-PVC-U double-wall bellows, iyipayipi elikhethekile elinodonga lwangaphakathi olubushelelezi, udonga olungaphandle lukathayela nezindonga ezingenalutho zangaphakathi nezingaphandle ezicutshungulwe futhi zakhiqizwa yi-polyvinyl chloride njengento eluhlaza eyinhloko.Ipayipi inokubukeka okuhle, isakhiwo esiyingqayizivele, amandla aphezulu, udonga lwangaphakathi olubushelelezi, ukumelana nokungqubuzana okuncane, ukujikeleza okukhulu, isisekelo asidingi ukwenza isisekelo sokhonkolo, isisindo esilula, ukuphatha kalula nokufakwa, ukwakhiwa okusheshayo;I-Rubber ring socket uxhumano, indlela ethembekile, kulula ukuqinisekisa ikhwalithi yokwakha;Isixhumi esibonakalayo esivumelana nezimo.Ukumelana okuqinile kokuhlala okungalingani;Ukumelana nokuvuza okuhle, ukumelana nokugqwala ezinhlobonhlobo zemidiya yamakhemikhali;Asikho isikali epayipini, ngokuyisisekelo akudingeki ukuthi i-dredge, impilo yesevisi engcwatshwe iminyaka engaphezu kwengu-50.

Impahla ebonakalayo

Ukuhlolwa kophawu lokuxhuma akuphuli, akukho ukuhlola komthelela wokuvuza kwe-TIR≤10% ukuqina kwendandatho S1≥4KN/㎡, S2≥8KN/㎡ ukuguquguquka kwendandatho akuphuli, izindonga ezimbili aziphumi kuhhavini ukuhlolwa ngaphandle kokuhlukana, ukuqhekeka, ibhamuza i-coefficient n=0.010.

2, ipayipi likathayela odongeni eliphindwe kabili le-HDPE

Ipayipi likathayela le-HDPE elinodonga oluphindwe kabili, elaziwa nangokuthi ipayipi likathayela elinezindonga eziphindwe kabili, iwuhlobo olusha lwepayipi elingasindi elenziwei-polyethylene ephezulu kakhulu.Inezici zesisindo sokukhanya, ukumelana nokucindezela okukhulu, ukuqina okuhle, ukwakhiwa okusheshayo nokuphila isikhathi eside, njll. Umklamo wayo omuhle kakhulu wesakhiwo sodonga unciphisa kakhulu izindleko uma kuqhathaniswa nezinye izakhiwo zamapayipi.Futhi ngenxa yokuthi ukuxhumana kulula futhi kuthembekile, sekusetshenziswe kabanzi ekhaya naphesheya.Amapayipi amaningi kakhonkolo ashintshayo kanye nepayipi lensimbi elicijile.Izici zokusebenza:

Ipayipi likathayela eliphindwe kabili le-HDPE linozinzo oluhle kakhulu lwamakhemikhali, ukumelana nokuguga kanye nokumelana nokuqhekeka kwemvelo.Izinsimbi ze-HDPE ezinodonga oluphindwe kabili ezikhiqizwe yizinto zayo ezingavuthiwe zingezepayipi eliguquguqukayo.Izici zayo zimi kanje:

Ukumelana okuqinile nokucindezela kwangaphandle: udonga lwangaphandle luyisakhiwo esiyisiyingi esiyindilinga, esithuthukisa kakhulu ukuqina kwendandatho yepayipi, ngaleyo ndlela kuthuthukise ukumelana kwepayipi ekulayisheni umhlabathi.Kulesi sici sokusebenza, ipayipi likathayela le-HDPE elinezindonga ezimbili linezinzuzo ezisobala uma liqhathaniswa namanye amapayipi.Izindleko eziphansi zobunjiniyela: ngaphansi kwesimo salowo mthwalo, ipayipi likathayela elinezindonga ezimbili ze-HDPE lidinga kuphela udonga oluncane ukuze lihlangabezane nezidingo.Ngakho-ke, uma kuqhathaniswa neshubhu eliqinile lodonga lokucaciswa kwezinto ezifanayo, lingonga cishe uhhafu wezinto zokusetshenziswa, ngakho-ke izindleko zepayipi likathayela elinodonga oluphindwe kabili le-HDPE nazo ziphansi.Lesi esinye isici esivelele kakhulu sepayipi.

Ukwakhiwa okulula: Ngenxa yesisindo esilula sepayipi likathayela elinezindonga ezimbili ze-HDPE, ukuphatha nokuxhuma kulula kakhulu, ngakho ukwakhiwa kuyashesha futhi ukugcinwa kulula.Ngaphansi kwesimo sesikhathi sokwakha esiqinile kanye nezimo ezingezinhle zokwakha, izinzuzo zayo zisobala kakhulu.Ukumelana okuhle kwezinga lokushisa eliphansi, ukumelana nomthelela: izinga lokushisa le-embrittlement le-HDPE double wall bellows lingu-70℃.Izimo ezivamile zokushisa eziphansi (ngaphezulu -30℃) azidingi ukuthatha izinyathelo zokuvikela ezikhethekile lapho kwakhiwa, ukwakhiwa kwasebusika kulula, futhi ipayipi likathayela le-HDPE elinodonga oluphindwe kabili linokumelana nomthelela omuhle.

Ukuzinza okuhle kwamakhemikhali: Ngenxa yokuthi i-molecule ye-HDPE ayinayo i-polarity, inokuqina okuhle kakhulu kwamakhemikhali.Ngaphandle kwama-oxidants ambalwa aqinile, imidiya eminingi yamakhemikhali ayikwazi ukuyibhubhisa.Umhlabathi, ugesi, i-asidi kanye nezici eziyisisekelo endaweni yokusetshenziswa okuvamile ngeke kulimaze ipayipi, awekho amabhaktheriya, akukho scaling, indawo yawo yokujikeleza ngeke yehle ngokunyuka kwesikhathi sokusebenza.

Impilo ende yesevisi:

Ngaphansi kwesimo sokungabikho kwemisebe yelanga ye-ultraviolet, i-HDPE double wall bellows ingasetshenziswa iminyaka engaphezu kwengu-50.Ubude obuthile be-HDPE i-double-wall ye-axial yepayipi likathayela bungagobeka kancane, akuthintwa izinga elithile lokuhlala okungalingani phansi, bungabekwa ngokuqondile endaweni engaqondile engaqondile njalo njalo.Izinzuzo:

I-1, isakhiwo esiyingqayizivele, amandla aphezulu, ukucindezelwa kokumelana nomthelela, udonga lubushelelezi, ukungqubuzana kuwukugeleza okukhulu kakhulu;Ukuxhumana lula ngokuhlanganyela uphawu, akukho ukuvuza.

2, isisindo esilula, isivinini sokwakha esisheshayo, izindleko eziphansi zokusebenza, izindleko eziphansi.

3, ama-molecule e-polyethylene hydrocarbon polymer anempilo ene-acidic ngokweqile ne-alkaline angcwatshwe iminyaka engaphezu kwemi-5, futhi aluhlaza, awanabo ubuthi, awaboli, awanakulinganiswa.

4, isisindo esincane, ukwakhiwa okusheshayo, ukunciphisa izindleko.

5, impilo yenkonzo engcwatshwe iminyaka engaphezu kwengama-50.

Noma ngabe kungamawele, noma ngabe afana kakhulu ngazo zonke izindlela, abazali bazoqaphela, kule mibhobho emibili enezindonga ezingewona amawele, kuwukuhlonza okulula, futhi uma sazi ngokwanele ngayo. , singakwazi.
