HDPE/LDPE kuphatikiza zinthu zotulutsa thovu, mawonekedwe ake, komanso kuwerengera kulemera kwake,

Chiwerengero chonse cha magawo a HDPE ndi LDPE 100

Wothandizira 0.5 gawo

Ac kukwapula wothandizira 3-10 gawo

Zinc oxide 1-2 gawo

Stearic acid 0.5 gawo

Antioxidant 1010 0.1 gawo

Mineral filler 3-15 gawo,

Momwemo, chiŵerengero cha kulemera kwa HDPE ndi LDPE ndi 10:90-90:10,

Momwemo, kusungunuka kwamadzimadzi (MFR) kwa HDPE yosankhidwa kuli pakati pa 3-6g / 10min, ndipo kusungunuka kwamadzimadzi (MFR) kwa LDPE kuli pakati pa 2-3g / 10min;

Monga makamaka: wolumikiza wothandizira amasankhidwa kuchokera ku dicumyl peroxide DCP kapena benzoyl peroxide BPO;

Monga makamaka: mineral filler imasankhidwa kuchokera ku calcium carbonate kapena mica powder.

Zomwe zidapangidwa pano zimaperekanso mtundu wa njira yokonzekera yazinthu zomwe zatchulidwa pamwambapa za HDPE/LDPE zophatikizira thovu, ntchito za konkire ndi:

Pakugawa chuma chilichonse,

(1) ndi granulation wa HDPE ndi LDPE kusakaniza extrusion, youma, kupeza m'munsi-zinthu,

Monga makamaka: ntchito amapasa wononga extruder, kuchita blended kuti HDPE ndi LDPE, zotsatira zabwino kusanganikirana, akhoza extrude mosalekeza, linanena bungwe lalikulu kwambiri;

(2) zinthu zoyambira zomwe zimapezedwa mu sitepe (1) zimakutidwa ndi mphero, mapulasitiki akugwira ntchito, m'zinthu zoyambira, onjezani wothandizira, pambuyo posakaniza ndi zinthu zoyambira, piritsi lophatikizika limachotsedwa, limatha kutentha,
