5 yakajairika kugadzirisa uye kugadzira nzira dzePE

PE inogona kugadziriswa uye kugadzirwa nenzira dzakasiyana.Kushandisa ethylene seyakanyanya mbishi zvinhu, propylene, 1-butene uye hexene secopolymers, pasi pechiito chezvinokonzeresa, uchishandisa slurry polymerization kana gasi polymerization process, iyo polymer inowanikwa nekupenya evaporation, kupatsanura, kuomesa uye granulation kuti uwane yunifomu zvidimbu zve chigadzirwa chapera.Izvi zvinosanganisira maitiro akadai sepepa extrusion, firimu extrusion, pombi kana profil extrusion, blow molding, jekiseni molding, uye roll molding.
Extrusion: Giredhi rinoshandiswa pakugadzira extrusion rinowanzo kunyunguduka index isingasviki 1, MWD iri pakati nepakati.Yakaderera MI panguva yekugadzirisa inoguma mune yakakodzera kunyunguduka simba.Huwandu hweMWD mamakisi anokodzera zvirinani kune extrusions nekuti iwo ane chiyero chepamusoro chekugadzira, yakaderera kufa yekuvhura kudzvanywa, uye yakaderera kunyungudika kuputika maitiro.
PE ine akawanda extrusion application senge waya, tambo, hoses, tubing uye profiles.Pipeline applications dzinotangira kubva kudiki-chikamu yellow chubhu yegasi chaiyo kusvika kune makobvu-akadzivirirwa matema machubhu 48 inches mudhayamita pamapombi eindasitiri nekanzuru.Mapaipi mahombe emadziro ane dhayamita mahombe ari kukurumidza kusimukira sedzimwe nzira dzemadhamu emvura uye mamwe mapombi ekongiri.
1.Sheet uye Thermoforming: Iyo thermoforming lining yemhando dzakawanda dzepikiniki dzinotonhorera dzakagadzirwa nePE yekuomarara, kureruka uye kusimba.Mamwe mashizha uye zvigadzirwa zve thermoforming zvinosanganisira mafenda, matangi linings, mahwendefa uye magadhi emabheseni, mabhokisi ekutumira nematangi.Zvichienderana nenyaya yekuti MDPE yakaoma, inoshingirira mukuora kwekemikari uye haipindire, nhamba huru uye iri kukurumidza kukura yemapepa ekushandisa ari mulch kana dziva rezasi Muri.
2.Blow molding: Inopfuura chikamu chimwe muzvitatu cheHDPE inotengeswa muUnited States ndeyekuvhuvhuta maapplication.Izvi zvinobva mumabhodhoro ane bleach, mafuta emota, detergent, mukaka uye mvura yakadirwa kusvika kumafiriji makuru, matangi emafuta emota uye inki cartridges.Blow molding mamakisi ane maitiro ekuita senge kunyungudika simba, ES-CR uye kuomarara kwakafanana neaya anoshandiswa pepa uye thermoforming maapplication, saka mamakisi akafanana anogona kushandiswa.
Jekiseni blow molding inowanzoshandiswa kugadzira zvigaba zvidiki (zvisingasviki 16 ounces) zvekurongedza zvinodhaka, shampoos, uye zvekuzora.Chakanakira chiitiko ichi ndechekuti mabhodhoro anogadzirwa nekubvisa otomatiki mabhodhoro, achibvisa kudiwa kwematanho ekupedzisira-ekupedzisira anowanzo kubatanidzwa nekuvhuvhuta maitiro.Nepo mamwe mamakisi akatetepa eMWD achishandiswa kunatsiridza kupera kwepasi, epakati kusvika pahupamhi MWD mamakisi anowanzo kushandiswa.
3.Injection molding: HDPE ine zvikumbiro zvisingaverengeki, kubva pamikombe yezvinwiwa yakaonda-yakakomberedzwa kusvika ku5-gsl makani anodya chikamu chimwe cheshanu cheHDPE inogadzirwa munyika.Magiredhi ejekiseni anowanzo aine melt index ye5 kusvika 10 uye inopa yakaderera kuyerera mamakisi ekuomarara uye epamusoro ekuyerera mamakisi ekuita machinability.Zvishandiso zvinosanganisira zvinodiwa zvezuva nezuva uye chikafu chitete madziro kurongedza;Magaba ezvokudya akaoma uye magaba epende;Kupokana kwakanyanya kune zvakatipoteredza kushushikana kuputsa maapplication akadai sediki enjini matangi emafuta uye 90 galoni marara magani.
4.Rolling: Zvishandiso zvinoshandisa nzira iyi zvinowanzopwanyika kuva zvinhu zveupfu zvinogona kunyunguduka uye kuyerera mumhepo inopisa.Mhando mbiri dzePE dzinoshandiswa kukungurutsa: general-chinangwa uye muchinjiko-yakabatana.General chinangwa MDPE/HDPE kazhinji ine density mu 0.935 kusvika 0.945 g/CC renji ine nhete MWD, zvichikonzera chigadzirwa chepamusoro chine warp shoma uye melt index renji ye3-8.Yepamusoro MI mamakisi kazhinji haana kukodzera nekuti iwo haana mhedzisiro yekupikisa uye kwezvakatipoteredza kusagadzikana kupwanya kuramba kunodiwa kune zvigadzirwa zvakaumbwa.
High performance rolling applications inotora mukana weiyo yakasarudzika zvimiro zvemakemikari akayambuka mamakisi.Aya magiredhi anoyerera zvakanaka panguva yekutanga chikamu chekuumbwa uye anobva abatanidzwa-yakabatana kuvandudza yavo yepamusoro yekushushikana kwezvakatipoteredza kuputsa kuramba uye kuoma.Kupfeka uye kusagadzikana kwemamiriro ekunze.Crosslinked polyethylene inonyanya kukodzera midziyo mihombe, kubva pamatangi mazana mashanu anoshandiswa kutakura makemikari akasiyana siyana kuenda ku20,000 galoni ekuchengetedza ekurima matangi.
5.Film: PE firimu rekugadzirisa rinowanzo tora iyo yakajairika inovhuvhuta firimu kugadzirisa kana flat extrusion processing nzira.Yakawanda PE ndeyemafirimu matete uye anogona kushandiswa pamwe neUniversal Low density PE (LDPE) kana mutsara Low Density PE (LLDPE).HDPE bhaisikopo mamakisi anowanzo shandiswa uko yakanakisa tensile zvivakwa uye yakanakisa impermeability inodiwa.Semuenzaniso, mafirimu eHDPE anowanzoshandiswa mumabhegi ezvigadzirwa, mabhegi ezvokudya uye kurongedza zvokudya.
