Tili ndi zaka zoposa 20 zogwira ntchito mu uinjiniya wa pulasitiki, makamaka mu pulasitiki wa PE. Ndife mamembala a bungwe la SRICI ndi CPPIA. Timatenga nawo mbali ndikulemba malamulo okhazikika a njira zopangira pulasitiki.
Tikhoza kupanga zosiyanaPepala la UHMWPEmalinga ndi momwe amagwiritsidwira ntchito. Monga momwe zilili ndi anti-UV anti-static komanso ndi zilembo zina, Ubwino kwambiri wokhala ndi pamwamba ndi mtundu wabwino umapangitsa pepala lathu la UHMWPE kukhala lodziwika kwambiri padziko lonse lapansi.
1.Uhmwpe sheetali ndi kukana kolimba komwe nthawi zonse kumakhala ndi polima ya thermoelectricity.
2. Uhmwpe sheet imakhala ndi kukana bwino kwambiri kugwedezeka ngakhale kutentha kutsika.
3. Uhmwpe sheet ili ndi low frictional factor, komanso zinthu zonyamulira zinthu zotsetsereka bwino.
4.Uhmwpe sheetali ndi mafuta odzola (osakulungidwa, omamatira).
5. Uhmwpe sheet ili ndi mankhwala abwino kwambiri oletsa dzimbiri komanso kukana kupsinjika maganizo.
6. Mapepala a Uhmwpe ali ndi luso labwino kwambiri lokonza makina.
7.Uhmwpe sheetali ndi madzi ochepa kwambiri (<0.01%).
8. Mapepala a Uhmwpe ali ndi paragon electric insulativity komanso antistatic behavior.
9. Chipepala cha Uhmwpe chili ndi mphamvu zambiri zotsutsana ndi ma radiation.
10.Uhmwpe sheetKuchuluka kwa zinthu zomwe zili ndi thermoplastics ndi kochepa kuposa ma thermoplastic ena (< 1g/m3).
11. Mapepala a Uhmwpe ali ndi kutentha kwa nthawi yayitali pogwiritsa ntchito: -269°C--90°C.
Mukafuna zinthu zodalirika komanso zolimba zomwe zingagwiritsidwe ntchito powononga kwambiri komanso kuwononga kwambiri, musayang'ane kwina kupatula pepala la UHMWPE. UHMWPE imayimira Ultra High Molecular Weight Polyethylene ndipo ndi pepala la pulasitiki lomwe limapereka magwiridwe antchito abwino kwambiri m'mikhalidwe yovuta kwambiri. Chifukwa cha kuphatikiza kwake kwapadera kwa zinthu, izi zikutchuka m'mafakitale osiyanasiyana.
Chimodzi mwa zinthu zazikulu zomwe pepala la UHMWPE limachita ndi kukwawa kwake kwambiri komanso kukana kugwedezeka. Kaya ndi kusweka kosalekeza kapena kusweka kwa kugwedezeka komwe kumachitika chifukwa cha zitsulo, chinthuchi chimatha kupirira. Kuyambira pa chute ndi hopper linings mpaka ma conveyor kapena zigawo, ma wear pad, ma machine rails, malo okhudzidwa ndi ma rail, mapepala a UHMWPE ndi omwe amasankhidwa kwambiri.
Koma si zokhazo! Pepala la UHMWPE lili ndi zabwino zina zambiri zomwe zimapangitsa kuti likhale lapamwamba kwambiri pa ntchito zaukadaulo. Choyamba, silimakhudzidwa ndi UV, zomwe zikutanthauza kuti limatha kupirira kuwala kwa dzuwa kwa nthawi yayitali popanda kuwonongeka. Izi zimapangitsa kuti likhale loyenera kugwiritsidwa ntchito panja, kuonetsetsa kuti limakhala nthawi yayitali komanso lodalirika nyengo iliyonse.
Chinthu china chodziwika bwino chaPepala la UHMWPEndi makina ake abwino kwambiri. Kuchepa kwa kukangana kwake komanso kusasinthasintha kwake kumapangitsa kuti ikhale chinthu chogwiritsidwa ntchito m'njira zosiyanasiyana pauinjiniya. Kaya kudula, kuboola kapena kupanga, mapepala a UHMWPE amatha kukonzedwa mosavuta kuti akwaniritse zofunikira zinazake, zomwe zimapulumutsa nthawi ndi khama.
Kuphatikiza apo, mapepala a UHMWPE sakhudzidwa ndi mankhwala. Amalimbana kwambiri ndi mankhwala osiyanasiyana, ma acid ndi maziko, zomwe zimapangitsa kuti akhale olimba ngakhale m'malo ovuta. Izi zimapangitsa kuti akhale abwino kwambiri kugwiritsa ntchito pazinthu zowononga.
Kuwonjezera pa kukana mankhwala,Pepala la UHMWPEs sizimatseka komanso sizimamatira. Izi zikutanthauza kuti zinthu ndi zinyalala sizimamatira kapena kumamatira pamwamba pake, zomwe zimapangitsa kuti ntchito yake ikhale yosavuta komanso kuti pasakhale zinthu zina zofunika kuzisamalira. Kaya ndi tirigu, malasha kapena zinthu zina, mapepala a UHMWPE amatsimikizira kuti madzi akuyenda bwino komanso kuti asatseke.
Kuphatikiza apo, pepala la UHMWPE lilinso ndi mphamvu zamagetsi zabwino kwambiri. Lili ndi mphamvu zamagetsi zambiri, zomwe zimapangitsa kuti likhale chotetezera kutentha chabwino kwambiri pakugwiritsa ntchito magetsi ndi zamagetsi. Chifukwa cha kusayamwa chinyezi komanso mphamvu zake zabwino zotetezera kutentha kwa magetsi zimapangitsa kuti likhale chisankho chodalirika m'malo osiyanasiyana ovuta.
Ubwino wina wa pepala la UHMWPE ndi kuthekera kwake kugwira ntchito bwino kutentha kozizira. Mosiyana ndi zinthu zina zomwe zimafooka kutentha kozizira kwambiri, pepala la UHMWPE limasunga kulimba kwake komanso kusinthasintha ngakhale kutentha kotsika kwambiri. Izi zimapangitsa kuti likhale loyenera kugwiritsidwa ntchito pofunikira kugwira ntchito bwino m'malo ozizira.
Ponena za kukana kutentha,Pepala la UHMWPEili ndi kutentha kwakukulu kogwira ntchito kwa 80°F. Izi zikutanthauza kuti imatha kupirira kutentha kwambiri popanda kusintha kulikonse kapenaKomabe, zofunikira zinazake zogwiritsira ntchito komanso zoletsa kutentha ziyenera kuganiziridwa kuti zitsimikizire kuti zikugwira ntchito bwino.
Pomaliza, kuyamwa kwa madzi kwa pepala la UHMWPE ndi kochepa kwambiri, kosakwana 0.01%. Izi zimapangitsa kuti likhale lolimba ngakhale m'malo onyowa, ndipo limachepetsa chiopsezo cha kutupa kapena kusintha kwa mawonekedwe. Izi zimathandizanso kuti ligwire ntchito bwino komanso likhale lolimba kwa nthawi yayitali.
Mbale ya pulasitiki ya UHMWPE imagwiritsidwa ntchito pamene pamakhala kusweka kapena pamene zitsulo zimakumana, zomwe zimapangitsa kuti pakhale kukangana kapena kusweka. Ndi yabwino kwambiri pa chute ndi hopper liners, conveyor kapena components, wear pads, ma machine guides, impact surface ndi guider rails.
Pomaliza,Pepala la UHMWPENdi njira yabwino kwambiri yothetsera mavuto omwe amafunikira kuvulala kwambiri komanso kukana kugwedezeka. Chifukwa cha zinthu zake zambiri zofunika monga kukana kwa UV, kusinthasintha, kusagwira bwino ntchito kwa mankhwala, kusagwirizana pang'ono, kusasunga bwino zinthu, mphamvu zamagetsi zabwino, kukana kuzizira, komanso kusayamwa madzi ambiri, yakhala chinthu chokondedwa kwambiri m'mafakitale osiyanasiyana. Chifukwa chake, kaya mukufuna kukana kuvulala kwambiri kapena zinthu zodalirika zopangidwa ndi akatswiri, pepala la UHMWPE ndiye yankho lanu!
