Tili ndi zaka zopitilira 20 muukadaulo wamapulasitiki, makamaka mu mapulasitiki a PE. Ndife mamembala a board a SRICI ndi CPPIA. Timatenga nawo mbali ndikujambula malamulo okhazikika a pulasitiki.
Tikhoza kupanga zosiyanaMapepala a UHMWPEmolingana ndi ntchito zosiyanasiyana .Monga anti-UV kugonjetsedwa ndi anti-static komanso ndi zilembo zina, Ubwino wabwino kwambiri wokhala ndi pamwamba ndi mtundu wabwino umapangitsa pepala lathu la UHMWPE kukhala lodziwika kwambiri padziko lonse lapansi.
1.Uwu pepakukhala ndi abrasive resistance yomwe nthawi zonse imakhala mu thermoelectricity polima.
Tsamba la 2.Uhmwpe limakhala ndi kukana kwamphamvu kwambiri ngakhale kutentha kochepa.
3.Uhmwpe pepala ndi otsika frictional factor, ndi bwino kutsetsereka kubala zinthu.
4.Uwu pepakukhala ndi lubricity (palibe caking, mu adhesion).
5.Uhmwpe pepala ndi bwino mankhwala dzimbiri kukana ndi nkhawa craze kukana.
6.Uhmwpe pepala ali kwambiri makina ndondomeko luso.
7.Uwu pepakukhala ndi madzi otsika kwambiri (<0.01%).
8.Uhmwpe pepala ali paragon magetsi insulativity ndi khalidwe antistatic.
9. Mapepala a Uhmwpe ali ndi mphamvu zabwino zokana radioactive.
10.Uwu pepaali ndi kachulukidwe ndi otsika kuposa thermoplastics ena (<1g/m3).
11. Mapepala a Uhmwpe amakhala ndi nthawi yayitali yogwiritsira ntchito kutentha: -269°C--90°C.
Mukayang'ana chinthu chodalirika komanso chokhazikika pamapulogalamu omwe amavala kwambiri komanso kukhudzidwa, musayang'anenso pepala la UHMWPE. UHMWPE imayimira Ultra High Molecular Weight Polyethylene ndipo ndi pepala lapulasitiki lomwe limagwira ntchito modabwitsa kwambiri. Ndi kuphatikiza kwake kwapadera kwa katundu, nkhaniyi ikupeza kutchuka m'mafakitale osiyanasiyana.
Chimodzi mwazinthu zazikulu za pepala la UHMWPE ndilakutidwa kwambiri komanso kukana kwake. Kaya ndi kuvala kosalekeza kapena kuvala kwachitsulo komwe kumachitika chifukwa cha zitsulo, izi zimatha kupirira. Kuchokera pazitsulo za chute ndi hopper kupita ku conveyors kapena zigawo, kuvala mapepala, njanji zamakina, malo okhudzidwa ndi njanji, mapepala a UHMWPE ndi chisankho choyamba.
Koma si zokhazo! Tsamba la UHMWPE lili ndi maubwino ena ambiri omwe amapangitsa kuti likhale lapamwamba kwambiri pazogwiritsa ntchito uinjiniya. Choyamba, imalimbana ndi UV, zomwe zikutanthauza kuti imatha kupirira kutentha kwa dzuwa kwa nthawi yayitali popanda kuwonongeka kulikonse. Izi zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito panja, kuonetsetsa kuti moyo wautali ndi wodalirika pa nyengo zonse.
Chinthu china chodziwika bwino chaChithunzi cha UHMWPEndi makina ake abwino kwambiri. Kugundana kwake kocheperako komanso kosavuta kukonza kumapangitsa kuti ikhale yosunthika pazinthu zaukadaulo. Kaya kudula, kubowola kapena kupanga, mapepala a UHMWPE amatha kukonzedwa mosavuta kuti akwaniritse zofunikira, kupulumutsa nthawi ndi khama.
Kuphatikiza apo, mapepala a UHMWPE sakhala otetezedwa ndi mankhwala. Imagonjetsedwa kwambiri ndi mankhwala osiyanasiyana, ma asidi ndi maziko, kuonetsetsa kukhulupirika kwake ngakhale m'madera ovuta. Izi zimapangitsa kuti zikhale zoyenera kwa mapulogalamu okhudzana ndi kukhudzana ndi zinthu zowononga.
Kuphatikiza pa kukana mankhwala,Chithunzi cha UHMWPEs alinso osatsekereza komanso osamata. Izi zikutanthauza kuti zinthu zakuthupi ndi zinyalala sizimamatira kapena kumamatira pamwamba pake, zomwe zimapangitsa kuti zigwire bwino ntchito komanso kuchepetsa zofunika zokonza. Kaya ndi tirigu, malasha kapena zinthu zina, mapepala a UHMWPE amaonetsetsa kuti madzi akuyenda bwino komanso kupewa kutsekeka.
Kuphatikiza apo, pepala la UHMWPE limakhalanso ndi zida zabwino kwambiri zamagetsi. Ili ndi mphamvu yayikulu ya dielectric, ndikupangitsa kuti ikhale insulator yabwino pamagetsi ndi zamagetsi. Mayamwidwe ake otsika chinyezi komanso zabwino zotchingira magetsi zimapangitsa kukhala chisankho chodalirika pazovuta zosiyanasiyana.
Ubwino wina wa pepala la UHMWPE ndikutha kuchita bwino m'malo ozizira. Mosiyana ndi zida zina zomwe zimawonongeka pakazizira kwambiri, pepala la UHMWPE limasungabe kulimba kwake komanso kusinthasintha ngakhale kutentha kwapansi paziro. Izi zimapangitsa kuti ikhale yoyenera kwa mapulogalamu omwe amafunikira kuchita bwino m'malo ozizira.
Pankhani ya kukana kutentha,Chithunzi cha UHMWPEili ndi kutentha kwapamwamba kwambiri kwa 80 ° F. Izi zikutanthauza kuti imatha kupirira kutentha kwambiri popanda kupunduka kulikonse kapenakunyozeka. Komabe, zofunikira zenizeni zogwiritsira ntchito ndi kuchepetsa kutentha ziyenera kuganiziridwa kuti zitsimikizidwe kuti zikugwira ntchito bwino.
Pomaliza, kuyamwa kwamadzi kwa pepala la UHMWPE ndikotsika kwambiri, kuchepera 0.01%. Katunduyu amapangitsa kuti zisamve chinyezi, ngakhale m'malo achinyezi, ndipo amachepetsa chiopsezo cha kutupa kapena kusintha kwa mawonekedwe. Izi zimapangitsanso kuti ntchito yake ikhale yokhalitsa komanso yolimba.
Pulasitiki ya UHMWPE imagwiritsidwa ntchito pomwe kutsetsereka kumachitika kapena pomwe zitsulo zimakumana, zomwe zimapangitsa kugundana kapena kukwapula. Ndiabwino kwambiri pama liner a chute ndi hopper, zotengera kapena zida, zobvala, zowongolera zamakina, zowongolera ndi njanji zowongolera.
Pomaliza,Chithunzi cha UHMWPEndiye yankho lomaliza pamapulogalamu omwe amafunikira kukwapula kwakukulu komanso kukana kwamphamvu. Ndi zinthu zake zambiri zofunika monga UV kukana, processability, inertness mankhwala, otsika mikangano, non-cake, katundu wabwino magetsi, kukana ozizira, ndi kutsika madzi mayamwidwe, wakhala zinthu zoyamikirika m'mafakitale osiyanasiyana. Chifukwa chake, kaya mukuyang'ana kukana kwapamwamba kwambiri kapena zida zodalirika zopangidwira, pepala la UHMWPE ndi yankho lanu!
