HDPE inkuta ebyiri zometseho umuyoboro wibikoresho,
HDPE kugirango ikorwe kabiri, Ni ubuhe bwoko bwa resin ya HDPE ikoreshwa kumirongo ibiri ikomye,

HDPE inkuta ebyiri zometseho umuyoboro wibikoresho

1. Ibigize ibikoresho fatizo: Ibikoresho fatizo bya PE inzogera ebyiri zubatswe muri rusange bigizwe na polyethylene, ibikoresho byingenzi byongerewe imbaraga hamwe na pigment.Niba ibikoresho bibisi bitose, kugirango tunoze umusaruro, defoamer ikwiye irashobora kongerwamo.

2, ibisabwa mubikorwa byibikoresho fatizo: uburyo bwo gutanga umusaruro uhendutse, inzogera nziza, ahanini biterwa no guhitamo ibikoresho fatizo no gukusanya amata.

Ibisabwa muri rusange kugirango imikorere ya polyethylene (PE) ikubiyemo umuvuduko wo gutemba (MFR), igihe cyo kwinjiza okiside (OIT) nubucucike.Ingano yikigereranyo cyamazi yerekana ubunini bwuburemere bwa molekile.Muri rusange, ibikoresho bifite umuvuduko mwinshi wo gutemba bifasha gutunganya no gukora, kandi birashobora guteza imbere umusaruro ushimishije.Ariko, ntishobora kuba nini cyane, ifite ingaruka zikomeye kumpeta ikomeye.Birakwiye guhitamo hagati ya 0.8-1.5g / 10min (190 ℃, 5kg).Igihe cyo kwinjiza Oxidation kigena igihe cyo kwangirika kwa okiside.Ku nzogera isaba imyaka 50 yo gukoresha, kugenzura igihe cyo kwinjiza okiside yibikoresho fatizo nurufunguzo rwo kwemeza ubuzima bwimyaka 50.Biteganijwe neza muri GB / T19472.1-2004 ko igihe cyo kwinjiza okiside yibikoresho fatizo bigomba kuba min20min (200 ℃).Kuri polyethylene yo hagati kandi nini cyane, imiterere yayo irashobora guhinduka muguhindura ubucucike.Kuberako tuzi ko ugereranije ubukana buke polyethylene irashobora kongera igihe cyayo cyo kunanirwa.

Icyiciro cya pipe ya HDPE gifite ubugari cyangwa bimodal gukwirakwiza uburemere bwa molekile.Ifite imbaraga zo guhangana n’ibisimba hamwe nuburinganire bwiza bwo gukomera no gukomera.Biraramba cyane kandi bifite sag nkeya iyo bitunganijwe.Imiyoboro yakozwe ikoresheje iyi resin ifite imbaraga nziza, gukomera no kurwanya ingaruka hamwe numutungo mwiza wa SCG na RCP.

Ibisigarira bigomba kubikwa mububiko bwateguwe, bwumye kandi kure yumuriro nizuba ryinshi.Ntigomba kurundarunda mu kirere.Mugihe cyo gutwara, ibikoresho ntibigomba guhura nizuba ryinshi cyangwa imvura kandi ntibigomba kujyanwa hamwe numucanga, ubutaka, ibyuma bisakara, amakara cyangwa ikirahure.Gutwara hamwe nibintu bifite ubumara, ibora kandi byaka birabujijwe rwose.

Gusaba

Urwego rwa HDPE rushobora gukoreshwa mugukora imiyoboro yumuvuduko, nkumuyoboro wamazi wumuvuduko, imiyoboro ya lisansi nindi miyoboro yinganda.Irashobora kandi gukoreshwa mugukora imiyoboro idafite umuvuduko nkumuyoboro wikubye kabiri, imiyoboro ihanamye, imiyoboro ya silicon-imiyoboro, imiyoboro yo kuhira ubuhinzi hamwe na aluminumplastique.Byongeye kandi, binyuze mu gukuramo ibintu (silane cross-guhuza), irashobora gukoreshwa mugukora imiyoboro ya polyethylene ihuza (PEX) mugutanga amazi akonje kandi ashyushye.
