iindaba

Nangona i-HDPE i-double-bellows ye-HDPE kunye ne-PVC i-double-bellows ebizwa ngokuba yi-double-bellows ebizwa ngokuba yi-double-bellows, kodwa ukongeza kwinkangeleko efana nencinci, kwiindawo ezininzi zahluke kakhulu, ukuba awukholelwa, jonga nje uthotho oluncinci ukuze udwelise ezi zahlukeneyo.

I. UPVC imingxunya kabini eludongeni

I-UPVC ivuthele eludongeni oluphindwe kabini, ekwaziwa ngokuba yiPVC-U double-wall bellows, ngumbhobho okhethekileyo onodonga lwangaphakathi olugudileyo, udonga lwangaphandle olugudileyo kunye neendonga ezimngxuma zangaphakathi nezingaphandle ezicutshungulwayo zaveliswa yipolyvinyl chloride njengeyona nto iphambili ekrwada.Umbhobho unenkangeleko enhle, isakhiwo esiyingqayizivele, amandla aphezulu, udonga lwangaphakathi olugudileyo, ukuchasana kwe-friction encinci, ukujikeleza okukhulu, isiseko akufuneki ukuba senze isiseko sekhonkrithi, ubunzima obulula, ukuphatha lula kunye nofakelo, ukwakhiwa ngokukhawuleza;Uxhulumaniso lwesokhethi yerubha, indlela ethembekileyo, kulula ukuqinisekisa umgangatho wokwakha;Ujongano oluthambileyo.Ukuchasana okunamandla ekuhlalweni okungalinganiyo;Ukuchasana nokuvuza okulungileyo, ukuxhathisa ukubola kwiindidi zeendaba zemichiza;Akukho sikali kumbhobho, ngokusisiseko akufuneki dredge, kungcwatywa ubomi benkonzo ngaphezulu kweminyaka engama-50.

Izinto eziphathekayo

Uqhagamshelo uvavanyo itywina alaphuki, akukho kuvuza impembelelo uvavanyo TIR≤10% ring ukuqina S1≥4KN/㎡, S2≥8KN/㎡ bhetyebhetye umsesane akaqhawuki, iindonga ezimbini aziphumi kuvavanyo lwe-oveni ngaphandle kokuqhekeka, ukuqhekeka, iqamu leManning uburhabaxa. umlinganiso n=0.010.

I-2, i-HDPE yodonga oluphindwe kabini umbhobho wethati

Umbhobho otyatyiweyo weHDPE, owaziwa ngokuba yipolyethylene eludongeni oluphindwe kabini, luhlobo olutsha lombhobho okhaphukhaphu owenziweyo.i-polyethylene ephezulu yoxinaniso.Ineempawu zobunzima bokukhanya, ukumelana noxinzelelo oluphezulu, ukuqina okuhle, ukwakhiwa okukhawulezayo kunye nobomi obude, njl njl. Uyilo olubalaseleyo lwesakhiwo sodonga lunciphisa kakhulu iindleko xa kuthelekiswa nezinye izakhiwo zemibhobho.Kwaye ngenxa yokuba uxhulumaniso lufanelekile kwaye luthembekile, lusetyenziswe ngokubanzi ekhaya nakwamanye amazwe.Imibhobho yesamente eninzi yokutshintsha kunye nombhobho wentsimbi.Iimpawu zokusebenza:

Umbhobho we-HDPE owenziwe kabini wodonga unozinzo oluhle kakhulu lweekhemikhali, ukuxhathisa ukuguga kunye nokuxhatshazwa koxinzelelo lokusingqongileyo.I-HDPE i-bellows ephindwe kabini eludongeni eveliswa yizinto zayo eziluhlaza zezombhobho oguquguqukayo.Iimpawu zayo zezi zilandelayo:

Ukuchasana okunamandla kuxinzelelo lwangaphandle: udonga lwangaphandle luyi-circular corrugated structure, eyandisa kakhulu ukuqina kombhobho, ngaloo ndlela ikhulise ukuchasana kombhobho kumthwalo womhlaba.Kulo mba wokusebenza, umbhobho we-HDPE owenziwe kabini eludongeni uneenzuzo ezicacileyo xa kuthelekiswa neminye imibhobho.Iindleko zobunjineli obuphantsi: phantsi kwemeko yomthwalo onjalo, i-HDPE yodonga oluphindwe kabini umbhobho we-corrugated idinga kuphela udonga oluncinci ukuhlangabezana neemfuno.Ke ngoko, xa kuthelekiswa netyhubhu eludongeni oluluqilima lwenkcazelo yemathiriyeli efanayo, inokonga malunga nesiqingatha sezinto ezikrwada, ngoko ke ixabiso le-HDPE lombhobho wamalahle odongeni oluphindwe kabini nawo liphantsi.Le yenye into evelele kakhulu yombhobho.

Ulwakhiwo olufanelekileyo: Ngenxa yobunzima bokukhanya kwe-HDPE umbhobho obiyelweyo ophindwe kabini, ukuphatha kunye nokudibanisa kulungeleka kakhulu, ngoko ke ukwakhiwa kukhawuleza kwaye ukugcinwa kulula.Ngaphantsi kweemeko zexesha lokwakha eliqinileyo kunye neemeko zokwakha ezimbi, iinzuzo zayo zibonakala ngakumbi.Ukumelana okuhle kobushushu obuphantsi, ukuxhathisa impembelelo: iqondo lobushushu le-embrittlement le-HDPE eludongeni oluphindwe kabini yi-70℃.Iimeko eziqhelekileyo zobushushu obuphantsi (ngaphezulu kwe-30 ℃) akufuneki ukuba zithathe amanyathelo okukhusela akhethekileyo xa ukwakhiwa, ukwakhiwa kwebusika kulungele, kwaye umbhobho we-HDPE owenziwe ngodonga oluphindwe kabini unokumelana nempembelelo elungileyo.

Uzinzo oluhle lweekhemikhali: Ngenxa yokuba i-molecule ye-HDPE ayinayo i-polarity, inozinzo oluhle kakhulu lweekhemikhali.Ngaphandle kwee-oxidants ezimbalwa ezomeleleyo, uninzi lwemithombo yeendaba zemichiza ayinakutshabalalisa.Umhlaba, umbane, i-asidi kunye nezinto ezisisiseko kwindawo yokusetyenziswa ngokubanzi aziyi kuwonakalisa umbhobho, akukho bhaktheriya, akukho sikali, indawo yayo yokujikeleza ayiyi kuncipha ngokunyuka kwexesha lokusebenza.

Ubomi benkonzo ende:

Ngaphantsi kwemeko yokungabikho kwelanga le-ultraviolet, i-HDPE ephindwe kabini eludongeni ingasetyenziselwa iminyaka engaphezu kwama-50.Ubude obuthile be-HDPE eludongeni olubiyelweyo lwe-axial yombhobho unokuguquguquka kancinane, awuchatshazelwa yinqanaba elithile lokuhlaliswa kokungalingani emhlabeni, unokubekwa ngokuthe ngqo kumjelo ongengowothi tye njalo njalo.Izinto eziluncedo:

I-1, isakhiwo esikhethekileyo, amandla aphezulu, ukunyanzeliswa kokumelana nempembelelo, udonga lugudileyo, ukukhuhlana kukuhamba okukhulu kakhulu;Unxibelelwano lula itywina joint, akukho kuvuza.

I-2, ubunzima obulula, isantya sokwakha ngokukhawuleza, iindleko eziphantsi zokusebenza, iindleko eziphantsi.

I-3, i-polyethylene hydrocarbon polymer molekyuli kwi-acidic kakhulu kunye ne-alkaline yangcwatywa ubomi ngaphezu kweminyaka emi-5, kwaye iluhlaza, ayinayo ityhefu, ayinayo i-corrosion, akukho scaling.

I-4, ubunzima obulula, ukwakhiwa ngokukhawuleza, ukunciphisa iindleko.

5, ubomi benkonzo obungcwatywe iminyaka engaphezu kwama-50.

Nokuba ngamawele, nokuba afane kakhulu ngandlela zonke, abazali baya kuqaphela, kwimeko yale mivumbo mibini enezindonga ezingengawo amawele, yinto elula yokuchongwa, kwaye ukuba siyazi ngokwaneleyo ngayo. , singa.
