Okwangoku, kunikezelo lwamanzi kunye nenkqubo yemibhobho yokuhambisa amanzi, imibhobho yeplastiki ngokuthe ngcembe ithathe indawo yemibhobho yemveli efana nentsimbi ekhuniweyo kunye nemibhobho yentsimbi efakwe amazimba kwaye ibe yimibhobho eqhelekileyo.Xa kuthelekiswa nemibhobho yesintu, imibhobho yeplastiki ineengenelo ezibalulekileyo ezifana nobunzima bokukhanya, ukuxhathisa ukubola, ukumelana nokuhamba kwamanzi aphantsi, ukonga amandla, ukufakwa okulula nokukhawulezayo, kunye neendleko eziphantsi, kwaye ithandwa luluntu lobunjineli bemibhobho.Ngexesha elifanayo, kunye nophuhliso olukhawulezayo lweshishini lepetrochemical kunye nenkqubela phambili eqhubekayo yeteknoloji yokuvelisa iplastiki, ukukhutshwa kwemibhobho yeplastiki kuye kwanda ngokukhawuleza, kwaye iintlobo zeemveliso ziye zahluka kakhulu.Ngaphezu koko, imibhobho yeplastiki iphumelele uphuhliso olukhulu kunye nophuculo kwithiyori yoyilo kunye nolwakhiwo lwetekhnoloji kulwakhiwo, kwaye yaqokelela amava asebenzayo atyebileyo, athe akhuthaza imibhobho yeplastiki ukuba ithathe indawo ebaluleke kakhulu ekwakheni unikezelo lwamanzi kunye nobunjineli bokuhambisa amanzi, kwaye yenze uphuhliso olungenakuthintelwa. umkhwa.
E-China, uninzi lwemibhobho yeplastiki esetyenziswa kwimibhobho yonikezelo lwamanzi ikakhulu ibandakanya imibhobho yokuhambisa amanzi ye-PVC-U, imibhobho ye-PP-R, i-aluminium-plastic composite pipes (PAP), i-steel-plastic composite pipes (SP), imibhobho ye-HDPE, njl. Umbhobho we-HDPE uvele kuphela kwimarike kwiminyaka engamashumi amabini edlulileyo.Yamkela itekhnoloji yemveliso ephezulu kunye nobuchwepheshe kwaye yenziwa yi-extrusion eshushu.Ineempawu zokuxhathisa umhlwa, udonga lwangaphakathi olugudileyo, ukuchasana nokuhamba okuphantsi, ukomelela okuphezulu, ukuqina okuhle kunye nobunzima obulula.
Emva kombhobho wonikezelo lwamanzi we-PVC-U, umbhobho we-HDPE uye waba ngowona mbhobho weplastiki wesibini osetyenziswa kakhulu ehlabathini.Okwangoku, imibhobho ye-polyethylene yoxinaniso oluphakathi okanye oluphezulu lwe-PE80 kunye ne-PE100 yamabanga kufuneka isetyenziselwe ukuhanjiswa kwegesi;imibhobho ye-polyethylene ephakathi okanye ephezulu yoxinaniso lwe-PE80 kunye ne-PE100 amabakala aqhele ukusetyenziswa kwimibhobho yokubonelela ngamanzi, kwaye i-PE63 iye yapheliswa ngokuthe ngcembe.Ngokumalunga nokuhanjiswa kwamanzi, eyona ikhula ngokukhawuleza yinkqubo yemibhobho ye-PE100, ekulindeleke ukuba ikhule ngaphezu kwe-10% kule minyaka mihlanu izayo.
