3. LLDPE
LLDPE ndi yopanda poizoni, yopanda pake komanso yopanda fungo, ndipo kachulukidwe kake kali pakati pa 0.915 ndi 0.935g/cm3.Ndi copolymer ya ethylene ndi pang'ono α-olefin yapamwamba kwambiri pansi pa chothandizira, chomwe chimapangidwa ndi polymerized ndi kuthamanga kwakukulu kapena kutsika kochepa.Mapangidwe a maselo a LLDPE ochiritsira amadziwika ndi msana wake wokhala ndi nthambi zochepa kapena zosatalika, koma uli ndi nthambi zazifupi.Kusowa kwa nthambi zazitali za unyolo kumapangitsa kuti polima ikhale yowala kwambiri.
Poyerekeza ndi LDPE, LLDPE ili ndi ubwino wokhala ndi mphamvu zambiri, kulimba kwabwino, kukhazikika kwamphamvu, kukana kutentha ndi kuzizira.

Mwachidule, zida zitatu zomwe zili pamwambazi zimagwira ntchito zawo zofunika pamitundu yosiyanasiyana ya ma projekiti odana ndi seepage.HDPE, LDPE ndi LLDPE onse ali ndi zotchingira zabwino, zoteteza chinyezi komanso zotsutsana ndi kuwomba, ndipo zinthu zawo zopanda poizoni, zosakoma komanso zopanda fungo zimawapangitsa kuti azigwiritsidwa ntchito kwambiri paulimi, ulimi wamadzi, nyanja zopangira, malo osungiramo madzi, ndi mitsinje, ndipo zakhala zikugwira ntchito mwamphamvu. kukwezedwa ndi kutchuka ndi Fisheries Bureau ya Unduna wa Zaulimi ku China, Shanghai Academy of Fishery Sciences, ndi Institute of Fishery Machinery and Instruments.
M'malo apakati a asidi amphamvu, maziko olimba, oxidant amphamvu ndi zosungunulira zakuthupi, zinthu za HDPE ndi LLDPE zitha kugwiritsidwa ntchito bwino komanso kugwiritsidwa ntchito, makamaka za HDPE polimbana ndi asidi amphamvu, alkali, makutidwe ndi okosijeni amphamvu ndi zosungunulira organic.Mbaliyi ndi yokwera kwambiri kuposa zida zina ziwirizi, kotero kuti koyilo ya HDPE yotsutsa-seepage ndi anti-corrosion yagwiritsidwa ntchito mokwanira m'mafakitale oteteza mankhwala ndi chilengedwe.
LDPE imakhalanso ndi asidi wabwino, alkali, njira yothetsera mchere, ndipo imakhala yowonjezereka bwino, kutchinjiriza magetsi, kukhazikika kwa mankhwala, kugwira ntchito kwa processing ndi kukana kutentha kwapansi, kotero imagwiritsidwa ntchito pa ulimi, ulimi wamadzi, ma CD, makamaka Imagwiritsidwa ntchito kwambiri posungira kutentha. ndi zipangizo chingwe.
Themakina opangira pulasitikizopangidwa ndi KHMC makamaka amagwiritsa ntchito HDPE kupanga zingwe za monofilament.Chingwe chapulasitiki chopangidwa ndi makina athu ndi champhamvu kwambiri komanso chamtundu wabwino kwambiri.
