High kachulukidwe Polyethylene utomoni
HDPE ndi crystalline non-polar thermoplastic resin yopangidwa kudzera mu copolymerization ya ethylene ndi pang'ono α-olefin monomer.HDPE imapangidwa pansi pa kupanikizika kochepa ndipo imatchedwanso low-pressure polyethylene.HDPE nthawi zambiri imakhala yolumikizana ndi maselo ndipo ili ndi nthambi zochepa.Ili ndi digiri yapamwamba ya crystallization komanso kachulukidwe kake.Imatha kupirira kutentha kwambiri ndipo imakhala ndi kukhazikika bwino komanso mphamvu zamakina komanso dzimbiri zotsutsana ndi mankhwala.
High kachulukidwe polyethylene utomoni mankhwala ndi granule kapena ufa, palibe makina zonyansa.Zogulitsazo ndi tinthu tating'onoting'ono tomwe timakhala ndi zida zabwino zamakina komanso zida zabwino kwambiri zopangira.Amagwiritsidwa ntchito kwambiri popanga mipope yotulutsa, mafilimu omwe amawombedwa, zingwe zolumikizirana, zotengera zopanda kanthu, malo ogona ndi zinthu zina.
Mawonekedwe
Mkulu kachulukidwe polyethylene kwa sanali poizoni, zoipa, palibe kununkhiza woyera particles, malo osungunuka ndi za 130 ° C, wachibale kachulukidwe wa 0.941 ~ 0.960.Ili ndi kukana kwabwino kwa kutentha ndi kukana kuzizira, kukhazikika kwamankhwala, komanso kumakhala ndi kukhazikika kwakukulu komanso kulimba, mphamvu zamakina zabwino.Ma dielectric katundu, kupsinjika kwa chilengedwe kusokoneza kugonana ndikwabwino.
Kugwiritsa ntchito
HDPE ndi crystalline non-polar thermoplastic resin yopangidwa kudzera mu copolymerization ya ethylene ndi pang'ono α-olefin monomer.HDPE imapangidwa pansi pa kupanikizika kochepa ndipo imatchedwanso low-pressure polyethylene.HDPE nthawi zambiri imakhala yolumikizana ndi maselo ndipo ili ndi nthambi zochepa.Ili ndi digiri yapamwamba ya crystallization komanso kachulukidwe kake.Imatha kupirira kutentha kwambiri ndipo imakhala ndi kukhazikika bwino komanso mphamvu zamakina komanso dzimbiri zotsutsana ndi mankhwala.Sinopec imapanga HDPE yokwanira, yomwe imakhudza magawo onse a mapulogalamu a HDPE, kuphatikizapo filimu, kuwombera, kuumba, jekeseni, mapaipi, waya & chingwe ndi zinthu zoyambira zopangira polyethylene ya chlorinated.
1. Kalasi ya Mafilimu a HDPE
Kalasi ya filimu ya HDPE imagwiritsidwa ntchito kwambiri popanga matumba a T-shirt, matumba ogula, matumba a chakudya, matumba a zinyalala, matumba oyikamo, matumba a mafakitale ndi mafilimu ambiri.Amagwiritsidwanso ntchito muzopaka zakumwa ndi mankhwala, zodzaza zotentha komanso zopangira zatsopano komanso filimu yotsutsa-seepage yomwe imagwiritsidwa ntchito muukadaulo wa hydraulic.
2. HDPE Blow Molding Grade
Gulu la HDPE lowumba nkhonya litha kugwiritsidwa ntchito popanga zotengera zazing'ono monga mabotolo amkaka, mabotolo amadzimadzi, mabotolo odzikongoletsera, zitini zamafuta opangira, migolo yamafuta agiya ndi migolo yamafuta opangira magalimoto.Itha kugwiritsidwanso ntchito popanga zotengera zapakatikati (IBC), zoseweretsa zazikulu, zinthu zoyandama komanso zotengera zazikulu ndi zapakatikati monga migolo yolongera.
3. HDPE Filament Grade
Gulu la HDPE la filament ndiloyenera kupanga filimu yonyamula, maukonde, zingwe ndi zotengera zazing'ono ndi zapakati.
4. Kalasi Yopangira jekeseni ya HDPE
Gulu la jakisoni wa HDPE limagwiritsidwa ntchito popanga ziwiya zotha kugwiritsidwanso ntchito, monga zotengera moŵa, zomangira zakumwa, zomangira chakudya, masamba amasamba ndi mabwalo a dzira ndipo zitha kugwiritsidwanso ntchito popanga thireyi zapulasitiki, zotengera katundu, zida zapanyumba, kugwiritsa ntchito zinthu zatsiku ndi tsiku ndi zoonda- zotengera chakudya khoma.Itha kugwiritsidwanso ntchito popanga migolo yogwiritsira ntchito mafakitale, nkhokwe zotayira zinyalala ndi zoseweretsa.Kupyolera mu extrusion ndi psinjika akamaumba ndondomeko ndi jekeseni akamaumba, angagwiritsidwe ntchito kupanga zisoti za madzi oyeretsedwa, mchere madzi, chakumwa tiyi ndi madzi chakumwa mabotolo.
5. Kalasi ya Chitoliro cha HDPE
HDPE chitoliro kalasi angagwiritsidwe ntchito kupanga mipope kuthamanga, monga mapaipi amadzi opsinjidwa, mapaipi gasi mafuta ndi mapaipi ena mafakitale.Itha kugwiritsidwanso ntchito popanga mapaipi osapumira monga mapaipi a malata apawiri-khoma, mapaipi omangira makhoma, mapaipi a silicon-core, mapaipi amthirira waulimi ndi mapaipi apawiri a aluminiyamu.Kuphatikiza apo, kudzera mu extrusion yokhazikika, itha kugwiritsidwa ntchito popanga mapaipi ophatikizika a polyethylene (PEX) popereka madzi ozizira ndi otentha.
6. HDPE Waya & Chingwe Gulu
Waya wa HDPE & kalasi ya chingwe imagwiritsidwa ntchito makamaka popanga jekete la chingwe cholumikizirana kudzera munjira zotulutsa mwachangu.
