Intsingiselo yemigca yokumakisha yeepayipi ze-PE ngemibala eyahlukileyo

Abantu abasebenzisa rhoqoUmbhobho we-PEukwakhiwa yazi ukubaUmbhobho we-PEumphezulu unemigca elinganayo enombala ofanayo, ozuba, omthubi, obomvu, ngoko ke ithetha ukuthini?Kwimarike yombhobho kamasipala waseTshayina, umbhobho wonikezelo lwamanzi kunye nombhobho werhasi ziimarike ezimbini ezinkulu zesicelo.I-PE yekhemikhali yegama lesiTshayina, i-polyethylene, izinto ze-PE ngenxa yamandla ayo aphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion, i-non-toxic, ukumelana nokugqoka kunye nezinye iimpawu, isetyenziswa ngokubanzi kwintsimi yokubonelela ngamanzi kunye nokuveliswa kwamanzi.Ngenxa yokuba ayiyi kuhlwa, ngoko ngumbhobho ofanelekileyo wokutshintsha umbhobho oqhelekileyo wokuhambisa amanzi ngentsimbi;Ngokokusetyenziswa kwayo, umphezulu wetyhubhu ye-PE uhlukaniswa ngemigca yokumakisha imibala eyahlukeneyo.Le mibala ilandelayo imele ukusetyenziswa okuninzi ngokulandelelanayo:

1.Umgca wamanqaku abomvu: Umbhobho we-PE

Phakathi kwazo zonke iiplastiki zobunjineli, ukuxhathisa kwe-HDPE kuthatha isithsaba seeplastiki, ukutsala amehlo.Okukhona buphezulu ubunzima bemolekyuli bezinto eziphathekayo, kokukhona ukuxhathisa ukunxiba, nangaphezulu kwezixhobo ezininzi zetsimbi (ezifana nentsimbi yekhabhoni, intsimbi engatyiwa, ubhedu, njl. njl.).Ngaphantsi kwemeko ye-corrosion enamandla kunye nokugqoka okuphezulu, ubomi bayo benkonzo ngama-4-6 amaxesha ombhobho wensimbi kunye namaxesha angama-9 e-polyethylene eqhelekileyo.Kwaye kuphuculwe impumelelo yosasazo ngama-20%.

I-flame retardant, ukusebenza kwe-antistatic kulungile, zonke zihlangabezana neemfuno eziqhelekileyo.Ubomi benkonzo ye-Downhole engaphezulu kweminyaka engama-20, inzuzo yezoqoqosho ephawulekayo, ukuchasana kwempembelelo, ukuxhathisa ukunxiba, ukuchasana kabini.

2.Umgca oluhlaza:Umbhobho wonikezelo lwamanzi we-PE, umbhobho wokukhupha amanzi, kunye nombhobho womlilo

Umbhobho we-PE blowdown: Umbhobho we-PE osetyenziselwa ukuvuthela ukwabizwa ngokuba ngumbhobho we-high-density polyethylene, eyi-HDPE ngesiNgesi.Olu hlobo lombhobho luhlala lusetyenziswa njengombhobho wobunjineli kamasipala, osetyenziswa ikakhulu kwi: ishishini lokucoca ugutyulo.Ngenxa yokunganyangeki kwayo, ukuxhathisa kwe-asidi, ukuxhathisa kwe-corrosion, ukumelana nobushushu obuphezulu, ukumelana noxinzelelo oluphezulu kunye nezinye iimpawu, ngokuthe ngcembe ithathe indawo yendawo yombhobho wentsimbi yemveli, umbhobho wesamente kunye neminye imibhobho emarikeni, ngakumbi kuba umbhobho ulula ubunzima kwaye kulula ukuyifaka kunye nokuhamba, lolona khetho lungcono lwezinto ezintsha.

Umbhobho wonikezelo lwamanzi we-PE: Umbhobho we-PE wonikezelo lwamanzi yimveliso yokutshintshwa kombhobho wentsimbi yemveli kunye nombhobho wamanzi okusela we-PVC.Umbhobho wamanzi kufuneka uthwale uxinzelelo oluthile, ngokuqhelekileyo ukhethe ubunzima obuphezulu be-molecular, iipropati ezingcono zomatshini we-PE resin, njenge-HDPE resin.I-resin ye-LDPE inamandla aphantsi obunzima, ukunyanzeliswa koxinzelelo oluphantsi, ukunyanzeliswa okungahambi kakuhle, ukuzinza okungahambi kakuhle kwe-dimensional xa kusenziwa kunye nokucutshungulwa, kunye nokudibanisa okunzima, ayifanelekanga njengesixhobo sombhobho wokuhambisa amanzi.Nangona kunjalo, ngenxa yesalathisi sempilo ephezulu, i-PE, ngakumbi i-HDPE resin, ibe yinto eqhelekileyo ekuveliseni imibhobho yamanzi okusela.I-resin ye-HDPE ine-viscosity encinci ye-melt, i-fluidity enhle kunye nokucutshungulwa lula, ngoko ke uluhlu olukhethiweyo lwesalathisi se-melt yalo lubanzi, ngokuqhelekileyo i-MI phakathi kwe-0.3-3g / 10min.

3.Umgca weleyibhile etyheli: umbhobho wegesi we-PE

Umbhobho we-PE wegesi yimveliso yokutshintshwa kombhobho wentsimbi yemveli kunye negesi yePVC.

Umbhobho wegesi kufuneka uthwale uxinzelelo oluthile, ngokuqhelekileyo ukhethe ubunzima obuphezulu be-molecular, iipropathi ezilungileyo zomatshini we-PE resin, njenge-HDPE resin.I-resin ye-HDPE inamandla aphantsi obunzima, ukunyanzeliswa koxinzelelo oluphantsi, ukunyanzeliswa okungahambi kakuhle, ukuzinza okungahambi kakuhle kwe-dimensional xa kusenziwa, kunye noxhulumaniso olunzima, alufanelekanga njengezinto zombhobho wokuhambisa amanzi.Nangona kunjalo, i-LDPE, ngakumbi i-resin ye-LLDPE, iye yaba yinto esetyenziswa ngokuqhelekileyo kumbhobho wegesi ngenxa yesalathiso sempilo ephezulu.I-LDPE, i-LLDPE i-resin melt viscosity incinci, i-fluidity enhle, ukucutshungulwa lula, ngoko ke uluhlu olukhethiweyo lwesalathisi sayo se-melt lubanzi, ngokuqhelekileyo i-MI phakathi kwe-0.3-3g / 10min.
