PP QP73N Jekeseni Woumba Gulu-Impact Copolymer
Sinopec ndiye omwe amapereka kwambiri PP impact copolymer ku China.Utotowu umapangidwa ndikulowetsa mphira wa ethylene-propylene mkati mwa semi-crystalline PP homopolymer matrix.Ili ndi kutentha kwakukulu kwa kutentha (HDT), kukana kukanda bwino, zabwino
kukana kwamphamvu pa kutentha kochepa, kukhazikika bwino kolimba komanso madzi abwino.Zopangidwa kuchokera ku utomoni uwu zimadziwika ndi kukonza mwachangu komanso kusinthika kwabwino.
PP ili ndi ntchito zosiyanasiyana.Ndi oyenera njira zingapo processing monga jekeseni akamaumba, extrusion akamaumba ndi kuwomba akamaumba ndipo chimagwiritsidwa ntchito mu nsalu, ma CD, zipangizo zamagetsi zapakhomo, galimoto ndi malo.
mafakitale.
Namwali PP Granules QP73N
| Kanthu | Chigawo | Zotsatira za mayeso |
| Melt Flow Rate (MFR) | g/10 min | 7.0-12.0 |

Kugwiritsa ntchito
Otaya yapakatikati, mkulu okhwima zimakhudza mankhwala copolymerization, jekeseni pulasitiki, ndi ntchito kwambiri crystallization ndi warping kukana ndi okhwima bwino makhalidwe, makamaka ntchito m'madera ambiri monga mafani magetsi, ophika mpunga, otsuka mbale ndi njinga yamoto makampani mpando mbale, chopondapo, etc. Iwo akhoza amagwiritsidwanso ntchito mkati mwagalimoto ndi zisoti zamabotolo apulasitiki.
Kulongedza katundu ndi mayendedwe
Utotowo umayikidwa m'matumba amkati opangidwa ndi filimu ya polypropylene kapena matumba a filimu ya FFS. Mu thumba la 25kg, 16MT mu 20fcl imodzi yopanda phale kapena 26-28MT mu 40HQ imodzi popanda phale kapena 700kg jumbo thumba, 26-28MT mu 40HQ imodzi popanda phale.
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.
