Parizvino, iyo huru yepasi pemvura inoshandiswapolyethylenemunyika yangu inosanganisira firimu, jekiseni kuumba, pombi, hollow, waya kudhirowa, tambo, metallocene, coating uye mamwe marudzi makuru.
Yekutanga kutakura mutoro, chikamu chikuru chepasi pemvura inoshandiswa ifirimu. Kune iyo indasitiri yechigadzirwa chemufirimu, iyo huru ifirimu rekurima, firimu reindasitiri uye firimu rekurongedza chigadzirwa. Nekudaro, mumakore achangopfuura, zvinhu zvakaita sezvirambidzo pamabhegi epurasitiki uye kudzokororwa kuderera kwekuda nekuda kwedenda zvakagara zvichivanetsa, uye vari kutarisana nemamiriro ezvinhu anonyadzisa. Iko kudiwa kwezvinhu zvechinyakare zvinoraswa epurasitiki firimu zvichatsiviwa zvishoma nezvishoma nekuzivikanwa kwemapurasitiki anoparara. Vazhinji vagadziri vemafirimu vari kutarisanawo nemaindasitiri ehunyanzvi hwekuvandudza tekinoroji, uye zvishoma nezvishoma vari kusimukira vakananga kumafirimu emaindasitiri anogona kudzokororwa ane simba rakasimba uye kuita. Nekudaro, nekuda kwekuparara kwemafirimu epurasitiki anoshatisa, pane zvinodikanwa zvakasimba zvekurongedza kwekunze, kana kudiwa kwemafirimu ekurongedza ekunze anoda kuchengetwa kwenguva yakareba kupfuura nguva yekuparara, uye mafirimu emaindasitiri nemamwe minda achiri kusagadziriswa, saka zvigadzirwa zvemufirimu zvicharamba zvichishandiswa. Yakave iripo sechigadzirwa chikuru kuzasi kwepolyethylene kwenguva yakareba, asi panogona kunge paine kuderera kwekukura kwekushandisa uye kuderera kwechikamu.
Pamusoro pezvo, maindasitiri akadai semajekiseni ekuumba, mapaipi, uye makomba ane hukama zvakanyanya nekugadzirwa uye hupenyu acharamba ari makuru evatengi zvigadzirwa kuzasi kwepolyethylene mumakore mashoma anotevera, uye acharamba achitongwa nezvivakwa, zvinodiwa zuva nezuva, uye maturusi ehurumende. uye midziyo. Hupenyu hwevanhu hwakabatana nezvinhu zvinogara kwenguva refu, uye kudiwa kwekuderedzwa kwechigadzirwa kunodzikiswa. Dambudziko guru rakatarisana nemaindasitiri ari pamusoro pari zvino nderekuti chiyero chekukura kwechikamu chekutengesa zvivakwa chakamira mumakore achangopfuura. Nekuda kwezvinhu zvakaita semhinduro isina kunaka pamanzwiro ekudya kwevagari anounzwa nedenda rinodzokororwa, kusimudzira kweindasitiri yezvigadzirwa kwakatarisana nekumwe kuramba kukura. Naizvozvo, shanduko yechikamu chenguva pfupi ishoma, isinganyanyi kukanganiswa nezvigadzirwa zvinoshatisa, iyo indasitiri yepombi inogona kukanganiswa nemitemo, nepo jekiseni kuumba uye maburi zvigadzirwa zvinonyanya kukanganiswa nevagari vemo manzwiro, uye chiyero chekukura. ichanonoka kwenhambo yenguva mune ramangwana rinogoneka.
Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, iyo yega uye kuvandudza kwevanhu kwezvigadzirwa zvepurasitiki, pamwe nekugadzirwa kwemhando yechigadzirwa uye zvinodiwa zvekugadzira zvinogara zvichikura. Naizvozvo, mune ramangwana, indasitiri yezvigadzirwa zvepurasitiki ichawedzera kudiwa kwezvimwe zvigadzirwa zvinovandudza mashandiro ezvigadzirwa zvepurasitiki, senge metallocenes, mapurasitiki anotenderedza, zvekupfeka uye zvimwe zvakakwirira-zvakawedzerwa zvigadzirwa kana zvigadzirwa zvine zvakasiyana zvinodiwa muminda yakakosha. . Pamusoro pezvo, nekuda kwekugadzirwa kwakanyanya kwemabhizinesi ekugadzirwa kwepolyethylene mumakore achangopfuura, zvichikonzera kukanganisa kwakakomba kwechigadzirwa, uye kukakavara pakati peRussia neUkraine mukati megore kwakakonzera mitengo yakakwira yemafuta kukwidza purofiti ye ethylene, uye kuwedzera kwemutengo. uye kugovera kwakaguma mune yakakomba chigadzirwa homogeneity. Pasi pemamiriro ezvinhu aripo, Vagadziri ve polyethylene vari kuwedzera kushingaira mukugadzirwa kwepamusoro-soro-yakawedzerwa zvigadzirwa zvakadai semetallocenes, rotational molding, uye machira, maererano nekuvandudzwa kwemaindastiri ezasi. Naizvozvo, kukura kwezvigadzirwa zvinogona kuwedzera kune imwe nhanho mune ramangwana.
Pamusoro pezvo, sezvo denda richiramba richienderera mberi, pamwe nekutsvagisa nekuvandudzwa kwemhando nyowani nevagadziri, polyethylene fibers, zvekurapa uye zvekudzivirira zvigadzirwa zvakakosha zvinoteverwa zvishoma nezvishoma uye zvinokudziridzwa, uye kudiwa kweramangwana kuchawedzerawo zvishoma nezvishoma.
