Kodi PES material ndi chiyani? Kusanthula mozama za katundu ndi ntchito za polyethersulfone
M'munda wa zipangizo zamakina, "zinthu za PES ndi chiyani" ndi funso lodziwika bwino, PES (Polyethersulfone, Polyethersulfone) ndi polima ya thermoplastic yapamwamba kwambiri, chifukwa cha mphamvu zake zamakina komanso kukana kutentha kwambiri, zomwe zimagwiritsidwa ntchito kwambiri m'madera ambiri ogulitsa mafakitale. M'nkhaniyi, tikambirana mwatsatanetsatane katundu wakuthupi, njira zokonzekera ndi madera akuluakulu ogwiritsira ntchito PES.
Zinthu zoyambira za PES
PES ndi amorphous thermoplastic material yokhala ndi kutentha kwambiri komanso kukhazikika kwamakina. Kutentha kwa magalasi ake (Tg) nthawi zambiri kumakhala pafupifupi 220 ° C, zomwe zimapangitsa kuti zikhale zokhazikika m'malo otentha kwambiri.PES ili ndi kukana kwambiri kwa okosijeni ndi hydrolysis, ndipo imatha kukana kuwonongeka pamene imapezeka kumadera amvula kapena kutentha kwa madzi kwa nthawi yaitali. Izi zimapangitsa kuti PES ikhale yabwino popanga magawo kuti agwiritsidwe ntchito m'malo ovuta.
Kukonzekera ndi Kukonza kwa PES
PES nthawi zambiri imakonzedwa ndi polymerization, makamaka yokhudzana ndi polycondensation ya bisphenol A ndi 4,4'-dichlorodiphenylsulfone. Nkhaniyi imakhala ndi ndondomeko yabwino ndipo imatha kukonzedwa m'njira zosiyanasiyana, kuphatikizapo kuumba jekeseni, extrusion ndi thermoforming.PES ikhoza kusinthidwa pa kutentha pakati pa 300 ° C ndi 350 ° C, zomwe zimafuna kuti wogwiritsa ntchito akhale ndi zida zabwino zogwirira ntchito ndi njira zowongolera. Ngakhale kuti PES ndiyovuta kukonza, zinthuzo zimakhala zokhazikika bwino komanso zomaliza.
Malo ogwiritsira ntchito kwambiri a PES
Zinthu za PES zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chakuchita bwino kwambiri. M'makampani amagetsi ndi zamagetsi, PES imagwiritsidwa ntchito kwambiri popanga kusungunula magetsi ndi zolumikizira chifukwa cha kutchinjiriza kwake komanso kukana kutentha, komanso imagwiritsidwanso ntchito kwambiri m'makampani azachipatala. Chifukwa cha kukana kwake kutentha kwambiri, kukana kwa hydrolysis ndi kukana kwa mankhwala, PES ndi chinthu choyenera kupanga zinthu zachipatala monga zida zopangira opaleshoni, zotengera zotsekereza ndi zosefera.
PES mu Chithandizo cha Madzi
Malo odziwika bwino ogwiritsira ntchito ndi madzi oyeretsera.PES amagwiritsidwa ntchito kwambiri popanga zingwe zochizira madzi chifukwa cha kusagwira bwino ntchito kwamankhwala komanso kukana kuipitsidwa. Ma nembanembawa amagwiritsidwa ntchito mu ultrafiltration ndi microfiltration systems ndipo amatha kuchotsa zolimba zoyimitsidwa ndi tizilombo tating'onoting'ono m'madzi ndikukhalabe ndi permeability komanso mphamvu zamakina. Pulogalamuyi ikuwonetsanso kufunikira kwa zida za PES pamapulogalamu apamwamba kwambiri.
Ubwino Wachilengedwe wa PES
M'dziko lamasiku ano lokonda zachilengedwe, zinthu zakuthupi za PES zimayang'ananso: PES ili ndi moyo wautali wautumiki komanso kukhazikika bwino, zomwe zimachepetsa kuchuluka kwa zinthu zomwe zimalowa m'malo mwake ndikuwononga, komanso kupanga kwake kumakhala kogwirizana ndi chilengedwe, popanda kufunikira kwa zosungunulira, zomwe zimapatsa mwayi wokhazikika.
Mapeto
Kuchokera pakuwunika mwatsatanetsatane mu pepalali, titha kunena kuti PES ndi zida zopangira thermoplastic zapamwamba kwambiri zomwe zili ndi zinthu zabwino kwambiri komanso ntchito zambiri. Kaya ndi gawo la zamagetsi ndi zamagetsi, zida zamankhwala kapena zochizira madzi, PES yawonetsa ubwino wapadera. Kwa owerenga omwe akufuna kudziwa "zomwe PES imapangidwa", PES ndi chinthu chofunika kwambiri chomwe chili ndi mphamvu zambiri komanso ntchito zambiri, ndipo idzapitiriza kugwira ntchito yofunika kwambiri pa chitukuko cha mafakitale chamtsogolo.
