Cufnaanta hoose ee Polyethylene 2102TN00
Polyethylene-cufnaanta-hooseeya (LDPE) waa xabagta synthetic iyadoo la adeegsanayo habka cadaadiska sare leh iyada oo loo marayo polymerization xagjirka bilaashka ah ee ethylene sidaas darteed waxaa sidoo kale loo yaqaan "polyethylene cadaadis-sare".Cadaadis hoose oo polyetylen ah oo aan lahayn ur, aan dhadhamin, qaybo cad oo aan sun ahayn ama budo.Barta dhalaalaysa waa 131 ℃.Cufnaanta 0.910-0.925 g/cm³.Barta jilicsanaanta 120-125 ℃.Heerkulka dhalmada -70 ℃.Heerkulka ugu sarreeya ee shaqeynaya 100 ℃.Iyada oo iska caabbinta kulaylka aad u fiican, iska caabbinta qabow, xidho caabbinta iyo guryaha dielectric, xasiloonida kiimikada.Ku dhawaad aan lagu milmi karin dareere kasta oo organic heerkulka qolka.U adkeysan kara daxalka kala duwan ee acid iyo alkali iyo xalalka milixda kala duwan.Polyethylene cadaadiska hooseeya ayaa si weyn loogu isticmaalaa warshadaha dawooyinka iyo kiimikada si loo sameeyo alaab godan, sida foosto, dhalooyin iyo haamaha kaydinta.Warshadaha cuntadu waxay u adeegsadaan samaynta weelasha baakadaha.Warshadaha mishiinada waxaa loo isticmaalaa in lagu sameeyo daboolka, gacan-qabsiga, taayirrada gacanta iyo qaybaha kale ee mishiinka guud, iyo warshadaha waraaqaha waxaa loo isticmaalaa in lagu sameeyo warqad synthetic ah.
Muuqaal
LDPE waxay leedahay wax qabad wanaagsan oo qaabaynta iyo filim samaynta guryaha indhaha ee wanaagsan, guryaha farsamaysan iyo guryaha xidhidhiyaha kulaylka, caabbinta qabow, heerkulka hooseeya iyo iska caabinta heerkulka sare.Filimka dhumucdiisuna wuxuu u adkeysan karaa habka jeermis-diridda ee lagu qooyay 90 ℃ biyo kulul.Waxaa si weyn loogu isticmaalaa warshadaha baakadaha.
Codsiga
LDPE (2102TN000) waa wax filim extrusion ah oo aad u wanaagsan, inta badan ku haboon soo saarista filim baakadaha culus, filim daadsan, filimka baakadaha kulaylka yareeyey iyo wixii la mid ah.

Xidhmada, Kaydinta iyo Gaadiidka
Xabagta waxa lagu baakadeeyay bacaha tolmada leh ee polypropylene ku dahaadhay filimada.Miisaanka saafiga ah waa 25Kg/bac.Xabagta waa in lagu kaydiyaa bakhaar qabyo ah, qalalan kana fog dabka iyo iftiinka qorraxda tooska ah.Waa in aan lagu soo ururin hawada furan.Inta lagu jiro gaadiidka, badeecadu waa in aan lagu soo bandhigin iftiinka qoraxda ama roobka waana in aan lagu wada qaadin ciid, carro, biro qashinka ah, dhuxusha ama muraayadaha.Gaadiidka ay wataan sunta, daxalka iyo walaxda gubanaysa waa mamnuuc.
