Vanhu vanowanzoshandisaPE pombikuvaka ziva izvozvoPE pombinzvimbo ine mitsetse inoenzana ine ruvara rwakafanana, bhuruu, yero, tsvuku, saka zvinorevei?Mumusika weChina wepombi pombi, pombi yemvura uye pombi yegesi misika miviri mikuru yekushandisa.PE chemikemikari Chinese zita, polyethylene, PE zvinhu nekuda kwesimba rayo rakakwirira, kukwirira kwekushisa kwekushisa, kusagadzikana kwekuora, kusina-chepfu, kupfeka kuramba uye humwe hunhu, hunoshandiswa zvakanyanya mumunda wekupa mvura uye kugadzirwa kwemvura.Nekuti haiite ngura, saka iri pombi yakanaka yekutsiva yakajairika iron yekupa mvura pombi;Zvinoenderana nekushandiswa kwayo, pamusoro pe PE chubhu inosiyaniswa neakasiyana mavara ekumaka mitsara.Mavara anotevera anomiririra kushandiswa kwakati wandei zvichiteerana:
1.Red mark line: PE mine pipe
Pakati pese mapurasitiki einjiniya, kusamira kweHDPE kunotora korona yemapurasitiki, inobata maziso.Kukwirisa huremu hwemamorekuru echinhu, ndiko kunowedzera kusapfeka, kutopfuura zvinhu zvakawanda zvesimbi (senge kabhoni simbi, simbi isina tsvina, bhuronzi, nezvimwewo).Pasi pemamiriro ekuora kwakasimba uye kupfeka kwepamusoro, hupenyu hwayo hwesevhisi ndeye 4-6 nguva yepombi yesimbi uye 9 nguva yeyakajairika polyethylene.Uye vandudza kutapurirana zvakanaka ne20%.
Flame retardant, antistatic performance yakanaka, zvese zvinosangana nezvinodiwa.Downhole sevhisi hupenyu hweanopfuura makore makumi maviri, zvinoshamisa mabhenefiti ehupfumi, kukanganisa kuramba, kupfeka kuramba, kaviri kuramba maitiro.
2.Mutsetse webhuruu:Pombi yemvura yePE, pombi yekudhonza, uye pombi yemoto
PE blowdown pombi: Iyo PE pombi inoshandiswa kuvhuvhuta inonziwo high-density polyethylene pipe, inova HDPE kuChirungu.Iri rudzi rwepombi rinowanzo shandiswa semanisipala engineering pombi, inonyanya kushandiswa mu: sewage treatment industry.Nekuda kwekupfeka kwayo kuramba, acid resistance, corrosion resistance, tembiricha yakakwira, high pressure resistance uye humwe hunhu, zvishoma nezvishoma yakatsiva nzvimbo yechinyakare simbi pombi, simende pombi uye mamwe mapaipi pamusika, kunyanya nekuti pombi yakareruka mukati. uremu uye nyore kuisa uye kufamba, ndiyo yakanakisa sarudzo yezvinhu zvitsva.
PE mvura yekupa pombi: PE pombi yekugovera mvura ndiyo inotsiviwa yechinyakare simbi pombi uye PVC mvura yekunwa pombi.Iyo pombi yemvura inofanirwa kutakura kumwe kudzvanywa, kazhinji sarudza yakakwira molecular uremu, zvirinani zvemichina zvePE resin, senge HDPE resin.LDPE resin ine yakaderera kusimba simba, kushomeka kumanikidza kuramba, kusimba kusimba, kushomeka kwemaitiro kugadzikana kana ichigadzira uye kugadzirisa, uye yakaoma kubatana, haina kukodzera sechinhu chemvura yekumanikidza pombi.Nekudaro, nekuda kweiyo yepamusoro hutano index, PE, kunyanya HDPE resin, yave chinhu chakajairika mukugadzirwa kwepombi dzemvura yekunwa.HDPE resin ine diki yakanyunguduka viscosity, yakanaka fluidity uye nyore kugadzirisa, saka sarudzo yemhando yeinonyunguduka index yakafarawo, kazhinji MI pakati pe0.3-3g / 10min.
3.Yellow label line: PE gasi pombi
PE pombi yegesi ndiyo inotsiva chigadzirwa chechinyakare simbi pombi uye PVC gasi.
Pombi yegesi inofanirwa kutakura kumwe kudzvanywa, kazhinji sarudza yakakwira mamorekuru huremu, yakanaka michina zvimiro zvePE resin, senge HDPE resin.HDPE resin ine yakaderera tensile simba, kushomeka kumanikidza kuramba, kushomeka kusimba, kuderera kwechimiro kugadzikana kana ichigadzira, uye yakaoma yekubatanidza, haina kukodzera sechinhu chemvura yekumanikidza pombi.Nekudaro, LDPE, kunyanya LLDPE resin, yave chinhu chinowanzo shandiswa kune gasi pombi nekuda kweiyo yepamusoro hutano index.LDPE, LLDPE resin melt viscosity idiki, yakanaka fluidity, nyore kugadzirisa, saka sarudzo yemhando yekunyunguduka kwayo yakakura, kazhinji MI pakati pe0.3-3g / 10min.
