High kachulukidwe polyethylene (HDPE) utomoni wapadera kwa mapaipi malata amapasa,
HDPE utomoni kwa chitoliro, HDPE utomoni wa mapaipi awiri malata mapaipi,

High kachulukidwe polyethylene (HDPE) utomoni wapadera kwa mapaipi malata amapasa awiri awiri.Zotsatira zikuwonetsa kuti ma resin apadera, otchedwa QHE16A/B motsatana, ali ndi modulus yopindika kuposa 1150 MPa, amasungunula mphamvu kuposa 1.60 MPa ndi nthawi yolowetsa oxidation pafupifupi 100 min.Magulu onse awiri a utomoni ali ndi kuthekera kwabwino komanso amakwaniritsa zofunikira popanga mapaipi amalata amitundu iwiri m'mabizinesi apakhomo.

Kalasi ya chitoliro cha HDPE ili ndi kugawa kwakukulu kapena kugawanika kwa ma molekyulu.Imakhala ndi kukana kolimba kwamphamvu komanso kukhazikika bwino kwa kuuma komanso kulimba.Ndi yolimba kwambiri ndipo imakhala ndi sag yochepa pamene ikukonzedwa.Mapaipi opangidwa pogwiritsa ntchito utomoni uwu amakhala ndi mphamvu zabwino, zolimba komanso zolimba komanso zolimba za SCG ndi RCP..

Utoto uyenera kusungidwa m'nyumba yosungiramo madzi, youma komanso kutali ndi moto ndi dzuwa.Asamawunjikane panja.Panthawi yoyendetsa, zinthuzo zisawonongeke ndi dzuwa lamphamvu kapena mvula ndipo siziyenera kunyamulidwa pamodzi ndi mchenga, nthaka, zitsulo, malasha kapena galasi.Kuyendera limodzi ndi zinthu zapoizoni, zowononga komanso zoyaka moto ndizoletsedwa.

Kugwiritsa ntchito

HDPE chitoliro kalasi angagwiritsidwe ntchito kupanga mipope kuthamanga, monga mapaipi amadzi opsinjidwa, mapaipi gasi mafuta ndi mapaipi ena mafakitale.Itha kugwiritsidwanso ntchito popanga mapaipi osaponderezedwa monga mapaipi okhala ndi malata apawiri, mapaipi omangira makhoma, mapaipi a silicon-core, mapaipi amthirira waulimi ndi mapaipi apawiri a aluminiumplastics.Kuonjezera apo, kudzera mu extrusion yogwira ntchito (silane cross-linking), itha kugwiritsidwa ntchito popanga mapaipi ophatikizika a polyethylene (PEX) popereka madzi ozizira ndi otentha.
