ntchito

Filimu yoyera, LDPE = polyethylene yotsika kwambiri, kapena polyethylene yothamanga kwambiri, ndi Polyethylene polymerized pansi pa zovuta kwambiri, kachulukidwe kake kali pansi pa 0.922.

HDPE = Polyethylene yolimba kwambiri, kapena polyethylene yotsika kwambiri.Kachulukidwe pamwamba pa 0.940.

Black geomembrane makamaka HDPE(high kachulukidwe polyethylene) geomembrane, woyera geomembrane makamaka LDPE(otsika kachulukidwe polyethylene) geomembrane.Kusiyanitsa pakati pa ziwirizi makamaka ndi kachulukidwe ndi ntchito, kachulukidwe kameneka kamakhala kokulirapo, kachulukidwe kameneka kamakhala kakang'ono, kameneka kanagwiritsidwa ntchito ngati zipangizo zamakono za geotechnical, zotsirizirazi zimagwiritsidwa ntchito ngati filimu yopyapyala.

Black geomembrane geomembrane wakuda ndi chifukwa geomembrane analowa wakuda masterbatch kupanga, mtundu uwu wa masterbatch particles molingana kujowina geomembrane kupanga njira, muzochitika bwino, pang'ono masterbatch akhoza pokonza chiwerengero chachikulu cha geomembrane, geomembrane masterbatch particles kwambiri. zosavuta Machining, izo sizidzakhudza khalidwe vuto la geomembrane.

White geomembrane ndi chifukwa geomembrane mkati anawonjezera woyera mbuye particles, woyera mbuye particles sizidzakhudza khalidwe la geomembrane.Ma geomembranes akuda ndi ochuluka kwambiri komanso amagwira ntchito kuposa ma geomembranes oyera a LDPE chifukwa ambiri mwa iwo ndi HDPE geomembranes.White LDPE geomembrane ntchito ngati mankhwala filimu pulasitiki, ntchito ndi ndi lonse.

Chifukwa kachulukidwe ka HDPE wakuda geomembrane ndi wamkulu kuposa LDPE woyera geomembrane, ntchito ziwiri adzakhala osiyana.Kuyerekeza kwamtundu wonse kumafunikanso kufananizidwa molingana ndi kugwiritsa ntchito ziwirizo muzomangamanga zomwezo, osati kuyerekeza kutalika kwa ziwirizo (palibe kufananiza).Amagwiritsidwa ntchito mosiyanasiyana pakumanga kosiyanasiyana, ndipo nthawi zina amakhala m'malo mwa wina ndi mnzake.

White LDPE geomembrane kuposa wakuda HDPE geomembrane ali extensibility bwino, kusinthasintha ndi wamphamvu kuposa HDPE wakuda geomembrane, kukwaniritsa zomanga projekiti yoyera LDPE geomembrane ndi m'badwo watsopano wa geotechnical seepage control material, kutha kuzolowera mu uinjiniya womwewo udzakhala wamphamvu kuposa wakuda. HDPE geomembrane, tsopano uinjiniya wambiri utha kuwonekanso pazogulitsa.

Monga tikuonera pamwambapa, wakuda HDPE geomembrane ndi woyera LDPE geomembrane ali ndi ntchito zosiyanasiyana mu ntchito zosiyanasiyana ndipo sangathe wamba.Mitundu iwiri ya mankhwala ili ndi mphamvu ndi zofooka zawo.Ubwino wa zinthu ziwirizi uyenera kuganiziridwa potengera maudindo osiyanasiyana.
