LDPE, kana yakaderera-density polyethylene, ipurasitiki yakakurumbira inoshandiswa mumhando dzakasiyana dzezvigadzirwa, kusanganisira kurongedza.LDPE inozivikanwa nekushanduka kwayo, simba, uye kujeka, zvichiita kuti ive sarudzo yakanaka kune akawanda akasiyana maapplication.Imwe yemhando dzakajairika dzeLDPE iLDPE kupisa shrink firimu, iro rinoshandiswa zvakanyanya muindasitiri yekurongedza.Kana iwe uchida kudzidza zvakawanda nezve magadzirirwo eLDPE uye basa revagadziri vemafirimu eLDPE mukuita uku, ramba uchiverenga.
Nzira yekugadzira yeLDPE inotanga nekutorwa kwe ethylene (a hydrocarbon gas) kubva kugasi rechisikigo kana naphtha.Mushure mekunge ethylene yawanikwa, inopinda maitiro anonzi polymerization, ayo anosanganisira kujoinha akawanda ethylene mamorekuru pamwechete kugadzira cheni refu dzeLDPE.Iyo polymerization process inogona kuitwa nenzira dzakasiyana, kusanganisira yakakwirira-kumanikidza polymerization kana yemahara radical polymerization, iyo inowanzoshandiswa kugadzira LDPE.
Mushure mekuita kwepolymerization, iyo LDPE inobva yanyungudutswa uye kuumbwa kuita chimiro chaunoda, senge firimu, kuburikidza nenzira inonzi extrusion.LDPE kupisa kupisa firimu, kunyanya, inogadzirwa uchishandisa yakasarudzika fomu yeextrusion inonzi blown film extrusion.Mukuita uku, iyo LDPE inonyungudutswa uye kumanikidzirwa kuburikidza nekufa kwedenderedzwa, iyo inogadzira chubhu yepurasitiki yakanyungudutswa.Iyo chubhu inozokwiridzirwa, kana kuti "kuvhuvhuta," nemhepo kuti itambanuke uye kuigadzira muhukobvu nehupamhi hunodiwa.Firimu racho rinobva ratonhodzwa roiswa pamipumburu mikuru kuti riwedzere kugadziridzwa uye kuparadzirwa.
Kana firimu reLDPE ragadzirwa, rinowanzo tengeswa kuvagadziri vemafirimu eLDPE, vanogona kuenderera mberi nekugadzirisa zvinhu uye voshandura kuita mhando dzakasiyana dzezvigadzirwa zvekurongedza, kusanganisira kupisa kupisa firimu.LDPE vagadziri vemafirimutamba basa rakakosha mukugadzira nekupa kukosha-kwesevhisi masevhisi, akadai sekudhinda, laminating, uye kushandura iyo LDPE firimu kuita zvigadzirwa zvakapedzwa zvinosangana nezvinodiwa chaizvo nevatengi vavo.
Pamusoro pekugadzira uye kugadzirisa kweLDPE firimu,LDPE vagadziri vemafirimuvanewo basa rekuona kunaka uye kuenderana kwezvinhu.Izvi zvinosanganisira kuitisa bvunzo dzakakwana uye nhanho dzekudzora mhando kuona kuti firimu reLDPE rinosangana nezvinodiwa uye zviyero zvekushandisa kwarinoda.Vagadziri vemafirimu eLDPE vanogonawo kushanda padhuze nevatengi vavo kuti vape hunyanzvi hwekuita nerutsigiro, zvichivabatsira kusarudza mhando chaiyo yefirimu reLDPE kune zvavanoda pakurongedza.
Mukupedzisa, LDPE ipurasitiki inoshandiswa zvakasiyana-siyana uye inoshandiswa zvakanyanya iyo inogadzirwa kuburikidza nemaitiro epolymerization uye extrusion.Vagadziri vemafirimu eLDPE vanoita basa rakakosha mukugadzira uye kugadzirisa firimu reLDPE, kusanganisira kugadzirwa kweLDPE kupisa kupisa firimu.Nekupa kukosha-akawedzera masevhisi uye nekuona kunaka kwezvinhu, vagadziri vemafirimu eLDPE vanobatsira mukugadzirwa kwakanaka uye kwepamusoro-soro kwezvigadzirwa zvekurongedza zveLDPE.Kana iwe uchida firimu reLDPE pane zvaunoda pakutakura, ita shuwa yekudyidzana neane mukurumbira LDPE mugadziri wefirimu anogona kuzadzisa zvaunoda chaizvo.
