Excellent physical properties.Kuita kwepakati density polyethylene iri pakati pepamusoro uye yakaderera density polyethylene.Haisi kungochengetedza kuomarara uye simba repamusoro density polyethylene, asiwo ine yakanaka kuchinjika uye inokambaira kuramba, uye yakakwirira density polyethylene inonyanya kupisa.Hunhu hweakanakisa fusion yekubatanidza kuita anobatsira pakuiswa kwepombi dzepurasitiki.
Corrosion resistance uye hupenyu hurefu hwebasa.Munzvimbo dzemahombekombe enyika yedu, mvura yepasi yakakwirira uye hunyoro hwevhu hwakakwirira.Kushandiswa kwepombi dzesimbi dzisina musono kunofanirwa kuve kunopesana nekuora uye kunze kushatirwa pakuiswa, uye hupenyu hwesevhisi hungori makore makumi matatu, nepo mapaipi ePE anogona kumira zvakasiyana-siyana zvemakemikari media.ngura, pasina anti-corrosion kurapwa.Zvakare, haikurudziri algal, bhakitiriya kana fungal kukura uye ine hupenyu hwemakore makumi mashanu.
Kusimba kwakanaka uye kuchinjika.PE pombi imhando yepamusoro-yakasimba pombi, kureba kwayo panguva yekuzorora inopfuura 500%, ine simba rekuchinjika kune isina kuenzana kugadzika uye kupatsanurwa kwepombi hwaro, uye ine yakanaka seismic kuramba.Izvo zvinosimbiswa kuti iyo PE pombi ndiyo pombi ine yakanyanya kuvhunduka kusagadzikana.Pane chirevo chinoti mukudengenyeka kwenyika kuKobe kuJapan muna 1995, mapaipi ePE nemapombi emvura ndiwo chete mapaipi asina kukuvara.Mukuwedzera, kushanduka kwePI pombi ndeyokuti PE pombi inogona kuvharwa, kuderedza nhamba huru yekubatanidza pombi fittings.Nhungamiro ye PE pombi inogona kuchinjwa nyore nyore maererano nezvinodiwa nzira yekuvaka.Panguva yekuvaka, zvipingamupinyi zvinogona kudziviswa mukati mekutenderwa kubhenda radius yepombi kuderedza kuoma kwekuvaka.
Huwandu hwekutenderera hwakakura uye hupfumi hunodhura.Rusvingo rwemukati rwe PE pombi rwakatsetseka uye haruna kuyera.Iyo yakaenzana yakazara roughness reshiyo yemukati wepamusoro pepombi yePE i1/20 yeiyo pombi yesimbi.Kuyerera kwepaipi yePE pombi ine dhayamita imwechete yepombi, kureba kwakafanana uye kudzvinyirira kwakafanana kunenge 30% yakakura kupfuura iyo yepombi yesimbi, saka hupfumi hwehupfumi huri pachena.Kuenzaniswa nemapombi esimbi, mapaipi ePE anogona kudzikisa mari yeprojekiti nechikamu chimwe muzvitatu, uye mapaipi madiki edhiyamita anogona kubatanidzwa anogona kudzikisa mutengo wepurojekiti., Kubatana kuri nyore, kuvaka kuri nyore, uye nzira dzakasiyana.Iyo PE pombi muviri yakareruka, iri nyore kubata, iri nyore kupinza, uye ine mashoma majoini ewelding.Kana pombi yakareba, pombi yecoil inogona kushandiswa kuisa PE pombi mugero.Izvo zvinodikanwa zvakaderera zvakanyanya kupfuura simbi pombi mugero, uye kana mamiriro ekuvaka ari mashoma, electrofusion welding inogona kushandiswa.Mukuwedzera, nzira yekudzikisa pombi inogona kushandiswa kuisa pasi pemvura, iyo inoderedza zvikuru kuoma kwekuvaka uye mari yeinjiniya.
Kuiswa chisimbiso kwakanaka.Iyo PE pombi pachayo yakasungirirwa uye yakabatana, izvo zvinonyatso chengetedza kuzivikanwa kweiyo interface zvinhu, chimiro uye pombi muviri pachayo, uye inoona kubatanidzwa kwejoinhi uye pombi.Simba rinoputika uye simba rinoputika rehutano rakakwirira kudarika iro remuviri wepombi, iyo inogona kunyatsopikisa hoop stress uye axial stress inokonzerwa nekumanikidzwa kwemukati.Naizvozvo, zvichienzaniswa nemajoini emhando yerabha mhete kana mamwe majoini emuchina, hapana njodzi yekuvuza inokonzerwa nekukanganiswa kwemajoini, uye kuita kwekuisa chisimbiso kwakanaka kwazvo.
Zviri nyore kuchengetedza uye zvinogona kugadziriswa uye kuiswa pasina mvura uye gasi.
Good stress cracking resistance:PE pombiine yakaderera notch senitivity, yakakwira shear simba uye segmental anti-scratch kugona, uye yakasarudzika kwezvakatipoteredza kusagadzikana kusagadzikana.Yakanaka yakadzika tembiricha yekukanganisa kuramba: Iyo yakaderera tembiricha yekumisikidza tembiricha yePE pombi yakadzikira zvakanyanya, uye inogona kushandiswa zvakachengeteka mutembiricha ye -60 degrees Celsius.Muchikamu chekuchamhembe kwenyika yangu, apo polyethylene yakavigwa mvura inoiswa mumunda munguva yechando, inogumiswa kuti haina kukodzera kuisa kuvaka pasi pemadhigirii zero, nokuti pombi ye polyethylene iri nyore brittle.Good abrasion resistance.Iko kupfeka kupikisa kuenzanisa kuyedza kwepombi yepolyethylene uye pombi yesimbi inoratidza kuti kusagadzika kwayo kunowedzera ka4 pane yepombi yesimbi.
