Kodi BDPPA ndi chiyani? Kusanthula kokwanira kwa mawonekedwe ndi ntchito za polyethylene
Mu makampani azachipatala, hdpe ndi zinthu zofunika kwambiri, dzina lake lathunthu ndi lokwera kwambiri polyethylene (wapamwamba-polyethylene). Nkhaniyi ikupatsani yankho mwatsatanetsatane ndi kuwunika kwakuya kwa machitidwe a HDPA, njira zake zopanga ndi ntchito zosiyanasiyana.
Malingaliro oyambira ndi kapangidwe ka mankhwala a hdpe
Kodi HDPPA ndi chiyani? Kuchokera pamalingaliro owoneka bwino, hdpe ndi polymoplastic polic yopangidwa ndi polymernation ya ethylene monomers. Kupanga kwake molecular kumadziwika ndi maunyolo wautali wa polyethylene wokhala ndi unyolo wambiri ndi ochepa mauta ambiri pakati pawo, zomwe zimapangitsa kuti khungu. Makonzedwe olimba kwambiriwa amaperekanso kachulukidwe kwambiri mu banja la polyethylene, makamaka pakati pa 0,940 g / cm³ ndi 0.970 g / cm³.
Zolimbitsa thupi zapamwamba za hdpe
Zinthu za HDPpe zimawonetsa zinthu zambiri zabwino chifukwa cha kusanja kwake kwapadera. Ili ndi mphamvu kwambiri ndipo imatha kupirira zipsinjo zapamwamba, zomwe zimapangitsa kuti zikhale bwino pakugwiritsa ntchito katundu.hdpe imakhala ndi kukana kwabwino kwa mankhwala, komwe kumapangitsa kuti zigwirizane ndi mankhwala.
HDPA imakhalanso ndi kutentha kwabwino kwambiri, kumatha kukhalabe olimba mtima m'malo -40 ° C popanda kukhala wopanda nkhawa. Ilinso ndi katundu wabwino wamagetsi, omwe apangitsa kuti agwiritse ntchito muyeso wa mawaya ndi zingwe.
Kupanga HDPE ndi kukonza njira
Pambuyo kumvetsetsa mtundu wa hdpe ya hdpe ya hdpe ya hdpe ya hdpe ya hdpe ya hdpe ya hdpe ya hdpe yake, tiyeni tiwone njira yake yopanga kapena njira yochepetsera polymerisation. Malingaliro awa amabwera chifukwa cha HDPE yokhala ndi mitengo yotsika kwambiri ya crystallissotion, zomwe zimapangitsa kuti pakhale kuchuluka kwa polyethylene.
Zipangizo zabwino za HDPA zimakhala ndi mwayi wopangidwa ndi njira zosiyanasiyana zopangira zinthu, monga jakisoni wokumba, kuwomba nkhungu ndikukula ndikukula. Zotsatira zake, hdpe imatha kupangidwa m'njira zambiri monga matope, mafilimu, mabotolo ndi zotengera za pulasitiki.
Magawo osiyanasiyana ogwiritsa ntchito hdpe
Chifukwa cha zinthu zambiri zabwino za HDPPE, imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Mu mafakitale ogulitsa, hdpe amagwiritsidwa ntchito popanga mitundu yosiyanasiyana yamabotolo apulasitiki, mafilimu a chakudya, etc. M'makampani omanga, hdpe amagwiritsidwa ntchito popanga mapaipi am'madzi ndi mapaipi a mafuta, ndipo kukana kwawo komanso kukana kwamphamvu kumapangitsa kuti zikhale zodalirika m'malo ovuta.
Muzachigawo chaulimi, hdpe amagwiritsidwa ntchito popanga mafilimu olima, ma rade ndi zinthu zina, komwe kukana kwa UV ndi kukhazikika kumatsimikiziranso zokutira kwa mawaya ndi zingwe, komanso mkati mitundu yosiyanasiyana yolimbana ndi mitundu ndi zotengera.
Mapeto
HDPA ndi polictostic zinthu zakumphumu ndi zinthu zabwino kwambiri monga mphamvu yayikulu, kukana kwa mankhwala, kutentha pang'ono kukana komanso kusinthasintha kosavuta. Ili ndi mapulogalamu osiyanasiyana mu mankhwala, zomanga, ulimi ndi magawo ena. Ngati mukuganiza kuti "HDPPA YABWINO"
