Intsimbi eyomeleziweyo yombhobho odibeneyo we-thermoplasticsineempawu eziqhelekileyo ze-anti-corrosion, akukho scaling, ukuxhathisa okugudileyo okuphantsi, ukugcinwa kobushushu akukho wax, ukuxhathisa ukunxiba, ubunzima obukhanyayo kunye neminye imibhobho yeplastiki, kunye nesakhiwo sayo esisodwa senza ezi mpawu zilandelayo:
(1) Ukuxhathisa okuhle kwe-creep kunye namandla aphezulu ahlala esebenza ngoomatshini
Ngenxa yokuba iiplastiki ziya kukhwela kwiqondo lokushisa kunye phantsi koxinzelelo, kwaye i-brittle fracture iya kwenzeka phantsi koxinzelelo oluphezulu, uxinzelelo oluvumelekileyo kunye nomthamo wokuthwala imibhobho yeplastiki ecocekileyo iphantsi kakhulu (ngokubanzi ngaphakathi kwe-1.0Mpa).Amandla omatshini wentsimbi malunga namaxesha angama-10 e-thermoplastics, kwaye izinzile kwaye ayifuni ngaphakathi kwinqanaba lobushushu leplastiki.Xa ifreyimu yocingo lwentsimbi yomnatha idityaniswe neplastiki, ukukhahlela kweplastiki kunokuthintelwa ngokufanelekileyo kwaye amandla ahlala ehleli eplastiki anokuphuculwa kakhulu.Ngoko ke, uxinzelelo oluvumelekileyo lwepayipi ye-polyethylene edibeneyo kunye ne-wire mesh skeleton iphindwe kabini kunombhobho weplastiki.
(2) Ukumelana nobushushu obuhle
Amandla etyhubhu yeplastiki ngokuqhelekileyo ehla ngokunyuka kwamaqondo obushushu phakathi koluhlu lobushushu bokusetyenziswa kwayo, kwaye amandla etyhubhu yeplastiki ehla nge-10% ngokunyuka kobushushu nge-10℃.Ngenxa yokuba amandla wire mesh skeleton polyethylene umbhobho composite malunga 2/3 ithwalwa wire mesh skeleton, ngoko amandla ayo kunye nokwanda kokusetyenziswa lobushushu kwaye ngaphantsi kwalo naluphi na uhlobo umbhobho ecocekileyo yeplastiki.Iziphumo zovavanyo zibonisa ukuba amandla ombhobho oxutywe wentsimbi yentsimbi yomnatha we-polyethylene wehla nge-5% ngokunyuka kwe-10℃.
(3) Ukuqina, ukuchasana okuhle kwempembelelo, uzinzo olufanelekileyo lomda, kunye nokuguquguquka okuphakathi, ukuqina kunye nokulungelelana okuthambileyo.
I-elastic modulus yentsimbi idla ngokumalunga namaxesha angama-200 kwi-high-density polyethylene.Ukuqina, ukuxhathisa impembelelo kunye nozinzo lwe-dimensional ye-polyethylene umbhobho odibeneyo kunye ne-wire mesh skeleton ingcono kunawo nawuphi na omnye umbhobho weplastiki ococekileyo ngenxa yokomeleza i-wire mesh skeleton.Ngelo xesha, ngenxa yokuba i-mesh metal skeleton ngokwayo iyisakhiwo esiguquguqukayo, umbhobho odibeneyo unakho ukuguquguquka kwi-axial direction.Ngoko ke, umbhobho uneempawu zokudibanisa okuqinileyo kunye nokuguquguqukayo, ekulayisheni nasekukhupheni, ukuthutha, ukulungelelaniswa kofakelo kunye nokuthembeka kokusebenza kuhle kakhulu.Ukufakwa komhlaba kunokugcina inani lenkxaso, ixabiso eliphantsi;Ufakelo oluphantsi komhlaba lunokumelana ngokufanelekileyo nomthwalo wempembelelo ngokukhawuleza obangelwa ukuhla, ukutyibilika kunye nezithuthi.Umbhobho omncinci wedayamitha encinci unokugotywa ngokufanelekileyo, kunye noyilo loncedo okanye ulungelelwaniso lwenyoka, gcina izixhobo zombhobho.
(4) I-coefficient yokwandiswa kwe-thermal encinci
Ngenxa yolwandiso lombhobho weplastiki umbhobho 10.6 ~ 12.2 × 10-6 (1/℃), umbhobho yeplastiki esulungekileyo intambo yokwandisa coefficient 170 × 10-6 (1/℃), wire mesh skeleton polyethylene umbhobho composite kumnatha intsimbi. imiqobo yamathambo, ukwandiswa okushushu kombhobho odibeneyo kuphuculwe kakhulu, ngaphantsi kunalo naluphi na uhlobo lombhobho weplastiki osetyenziswa ngokuqhelekileyo, ngovavanyo, Ukwandiswa komlinganiso wombhobho we-wire mesh skeleton polyethylene composite yi-35.4 ~ 35.9×10-6 (1/℃) , nto leyo kuphela 3 ~ 3.4 amaxesha ukuba umbhobho carbon steel eqhelekileyo.Iziphumo zovavanyo zibonisa ukuba isixhobo sembuyekezo yobushushu ayidingeki ngokubanzi kufakelo olungcwatyiweyo, kwaye umbhobho unokufunxwa (okanye ukhululwe) ngokubeka i-medering, ngaloo ndlela unciphisa iindleko zofakelo.
(5) Ukuqhekeka okukhawulezayo akuyi kwenzeka
Umbhobho weplastiki ococekileyo, ubukhulu becala umbhobho weplastiki osulungekileyo wedayamitha enkulu kubushushu obuphantsi phantsi kwenyathelo loxinzelelo oluqhubekayo lwe-circumaxial, kulula ukuvelisa ukuqhekeka okukhawulezileyo okubangelwa ziziphene zasekhaya, uxinzelelo loxinzelelo (ngoko nangoko kumakhulu eemitha ukuya kwiikhilomitha ngaphezulu), ngoko ke ngoku, isantya samazwe ngamazwe. ukuchasana nokuqhekeka kombhobho weplastiki kubeka phambili iimfuno eziphezulu, kunye ne-carbon steel ephantsi ayikho ingxaki ye-brittle fracture, Ubukho be-mesh yensimbi kuthintela ukuguqulwa kunye noxinzelelo lweeplastiki ekufikeleleni kwinqanaba elibalulekileyo lokuqhekeka ngokukhawuleza.Ke ngoko xa sithetha ngokwethiyori, akukho kuqhekeka okukhawulezileyo kombhobho odibeneyo wocingo lwe-polyethylene.
I-6) I-composite yensimbi kunye neplastiki iyinto efanayo kwaye inokwethenjelwa
Okwangoku, umbhobho odibeneyo wensimbi-yeplastiki kwimarike ngenxa yokuba indawo edibeneyo phakathi kwentsimbi kunye neplastiki yinto eqhubekayo yokujongana rhoqo, ukusetyenziswa kwexesha elide phantsi kwesenzo soxinzelelo olutshintshileyo kulula ukuchithwa, okubangelwa ukuvuza okuhlangeneyo, i-bottleneck shrinkage yangaphakathi, ukuvaleka kunye nokusilela.Xa kuthelekiswa nentambo yomnatha wamathambo wepolyethylene umbhobho oyintlanganisela yesakhiwo somnatha ngokuncamathelisa okukhethekileyo okunyibilikayo okutshisayo (i-HDPE elungisiweyo) ukuze iplastiki kunye neentambo zocingo zidityaniswe kwaye zihlanganiswe.Amandla okubophelela okuhlangeneyo kwezinto ezimbini zikhulu kwaye zifana, kwaye uxinzelelo loxinzelelo luncinci.
7) I-anticorrosion enamacala amabini
I-mesh yentsimbi ye-mesh skeleton idityaniswe kwiplastiki ngokusebenzisa umaleko okhethekileyo onyibilikayo oshushu.Imiphezulu yangaphakathi kunye nengaphandle yombhobho inokusebenza okufanayo kwe-anti-corrosive, ukumelana nokunxiba, udonga lwangaphakathi olugudileyo, ukuchasana nokuhanjiswa okuncinci, akukho nqanaba, akukho wax, isiphumo esicacileyo sokugcina amandla, esinoqoqosho ngakumbi kwaye silungele ukuthuthwa kokungcwatywa kunye nokutshabalalisa kokusingqongileyo. iimeko.
(8) Uzilandelela kakuhle
Ngenxa yobukho be-wire mesh skeleton, i-wire mesh skeleton skeleton ye-polyethylene umbhobho ohlanganisiweyo unokufunyanwa ngendlela eqhelekileyo yokubona imagnethi, ukunqanda umonakalo owenziwe zezinye iiprojekthi zokomba.Kwaye olu hlobo lomonakalo ngumbhobho weplastiki ococekileyo kunye neminye imibhobho engeyiyo eyentsimbi ukuvelisa owona monakalo.
(9) Ukulungelelaniswa okulula kunye nokuguquguqukayo kwesakhiwo semveliso kunye nokusebenza
Ubume kunye nokusebenza kwemveliso kunokulungelelaniswa ngokutshintsha ububanzi bocingo, isithuba somnatha, ubukhulu bomgangatho weplastiki, iplastiki kunye nohlobo, ukuze kuhlangatyezwane neemfuno zoxinzelelo olwahlukileyo, ubushushu kunye nomhlwa. ukuxhathisa.
(10) Ukudibanisa okukhethekileyo kombane odibeneyo, iindidi, ukufakela ngokukhawuleza kwaye kunokwethenjelwa
Ukudityaniswa kocingo lwentsimbi yesakhelo se-polyethylene umbhobho odibeneyo wamkela uqhagamshelo lwe-electrothermic kunye noqhagamshelo lweflange.Uqhagamshelo lwe-Electrothermic kukufaka umbhobho odityanisiweyo kumbhobho we-electrothermic, kunye nokufakelwa kombane kwintambo yokufudumeza yombane efakwe kumphezulu ongaphakathi wombhobho wokuwufudumeza.Okokuqala, ubuso obungaphakathi bombhobho wokufakelwa bunyibilikisiwe ukuvelisa ukunyibilika, kwaye ukunyibilika kwanda kwaye kuzalise isithuba sombhobho wokudibanisa kude kube indawo yangaphandle yombhobho nayo ivelise ukunyibilika, kwaye ezimbini zinyibilika kunye nomnye.Emva kokupholisa kunye nokwenza, umbhobho kunye nokufakelwa kombhobho zidibaniswe ngokusondeleyo ngokubanzi.
