Kusiyana pakati pa chitoliro cha gasi cha PE ndi chitoliro chamadzi cha PE

PE gasi chitoliro ndiChitoliro chamadzi cha PEzaPE payipi.PE imatchedwanso polyethylene.Padziko lapansi, mapaipi a polyethylene amagawidwa m'magulu asanu: PE32, PE40, PE63, PE80 ndi PE100.Zida zomwe zimagwiritsidwa ntchito popanga mapaipi amadzi a polyethylene ndi mapaipi a gasi a polyethylene makamaka PE80 ndi PE100, omwe ndi ovuta kugwiritsa ntchito, koma Zimabweretsanso zoopsa zambiri zobisika pakugwiritsa ntchito mapaipi a PE.

Chifukwa chake, National Bureau of Standards yasintha zambiri pamlingo watsopano wa GB/T13663-2000, ponena kuti magiredi osiyanasiyana a PE80 ndi PE100 a mapaipi operekera madzi amafanana ndi mphamvu zosiyanasiyana zamphamvu, kuletsa mphamvu yamanjenje mu muyeso wakale, ndikuwonjezera kutalika kwa nthawi yopuma.(Kuposa 350%), zomwe zimatsindika kulimba koyambira.

Kupanga kwapakhomo kwa mzerewu kumachokera ku PE100 zopangira.Izi zili choncho makamaka chifukwa cha kupita patsogolo kwaukadaulo m'zaka zaposachedwa.Mtengo wa PE100 uli pafupifupi wofanana ndi wa PE80.Komabe, pankhani ya magwiridwe antchito, PE100 ndiyabwinoko kuposa zida za PE80.Kuphatikiza apo, mapaipi operekera madzi a PE ndi zida za PE gas pipe extrusion line zasinthidwa mosalekeza, ndipo mapaipi a PE afika pamlingo woyamba wapadziko lonse lapansi.
