Chitoliro cha ma mesh achitsulo cha polyethylene
Kugwiritsa ntchito
M'zaka 20 zapitazi, mapaipi atsopano apulasitiki akhala akugwiritsidwa ntchito kwambiri m'minda yamadzi, gasi ndi magetsi.Makamaka ndi kukhathamiritsa mosalekeza komanso luso laukadaulo wa polyethylene polymerization, pali zida zochulukira zolimba za polyethylene.Kupititsa patsogolo kuchuluka kwa kuthamanga kwa mipope ya pulasitiki, makamaka m'zaka zaposachedwa, kudzera mu kafukufuku waukadaulo wamitundu yosiyanasiyana, ukadaulo wachitsulo-pulasitiki wopangidwa ndi pulasitiki watha kuthetsa mavuto a mapaipi a polyethylene (PE) potengera kuchuluka kwa kuthamanga, anti- dzimbiri, ndi ogwira kufalitsidwa awiri.Amagwiritsidwa ntchito pamitundu yambiri yamayendedwe amadzimadzi.
Kapangidwe: Izi ndi chimango cholimbikitsidwa chokhala ndi chingwe chapakati chawaya wachitsulo champhamvu kwambiri pambuyo popaka mankhwala, ndipo guluu wapadera wosungunuka ndi pulasitiki zimaphatikizidwa mu chitoliro chonse ndi njira yopangira extrusion.
Mawonekedwe
Kugwira ntchito kwachuma kwapaipi
Pogwiritsa ntchito kachulukidwe polyethylene monga zamkati ndi kunja wosanjikiza zipangizo, zitsulo mauna chigoba polyethylene pulasitiki gulu chitoliro ali ndi ntchito yabwino ya mankhwala polyethylene chitoliro.Chifukwa cha mphamvu ya mafupa achitsulo, chitoliro chophatikizika cha mulingo womwewo wa kukakamiza kumakhala ndi makulidwe ang'onoang'ono a khoma kuposa mapaipi apulasitiki oyera.Kuzungulira kogwira mtima kwa агеа ndikokulirapo, ndipo kukana kwa dzimbiri komanso kukana kuvala kumatsimikizira kuti moyo wautumiki wa chitoliro ukhoza kukhala wazaka 50, zomwe zimathandizira bwino magwiridwe antchito achuma.
Limbitsani mafupa kuti atseke bwino ming'alu
Kugwiritsiridwa ntchito kwa chitsulo champhamvu champhamvu kwambiri cha chitsulo cholimba monga kulimbikitsa mafupa kumalepheretsa kupanga ming'alu yosatha komanso kufalikira kwachangu kwa zinthu za polyethylene, ndipo kumakhala ndi mphamvu zopondereza (kuthamanga mwadzina kwa payipi yamadzi kumafika З.5МРа) ndi mlendo сгеер kukana, Apamwamba kwambiri kukana, ndi zizindikiro zake ntchito аге apamwamba mapaipi polyethylene.
