Chinachake chokhudza UHMW chomwe mungafune kudziwa

UHMW-PE imayimira Ultra High Molecular Weight Polyethylene.Ndi polyethylene (PE) yapamwamba kwambiri yomwe ilipo, yopangidwira ntchito zovuta komanso ntchito zosiyanasiyana.

Iwo amapereka ndalama mu angapo zovuta ntchito.Ultra High Molecular Weight ndiye chinsinsi cha mawonekedwe apadera a polima uyu.Utoto wake wolemera kwambiri wa polyethylene uli ndi kulemera kwa ma molekyulu a 3 mpaka 6 miliyoni, poyerekeza ndi 300,000 mpaka 500,000 pazitsulo zolemera kwambiri (HMW).Kusiyana kumeneku ndi komwe kumatsimikizira kuti zinthuzi ndi zamphamvu zokwanira kuti zitha kupirira ma abrasion komanso kukhudza bwino kuposa zinthu zotsika zama poly.Kulemera kwa molekyulu ya UHMW-PE kumatanthauza kuti sidzasungunuka kapena kuyenda ngati madzi osungunuka.Chifukwa chake njira zopangira zida zimachokera kuukadaulo wazitsulo zauda.UHMW-PE singasinthidwe ndikuwumbidwa ndi njira wamba pulasitiki processing (jekeseni akamaumba, kuwomba akamaumba kapena thermoforming).Kumangirira kophatikizika ndi njira yofala kwambiri yosinthira yomwe imagwiritsidwa ntchito ndi utomoniwu chifukwa umapanga chinthu champhamvu komanso chosasinthasintha.

UHMW imadziwika chifukwa cha kukana kwamphamvu kwa ma abrasion, kudzoza kwachilengedwe, kulimba kwamphamvu, mankhwala-, corrosion-, komanso kukana chinyezi komanso kuyimitsa kwamayimbidwe.

Chifukwa cha ma abrasion-, corrosion-, chemical- komanso chinyezi chosagwira, UHMW imagwiritsidwa ntchito nthawi zambiri m'malo omwe zinthu zitha kukhala zovuta kwambiri pazinthu zina.Ndi polima yotsika mtengo kwambiri yomwe imagwiritsidwa ntchito kupanga magawo otsika mtengo, apamwamba kwambiri.

UHMW ndi chinthu chodzipaka mafuta chomwe chimawonetsa mavalidwe abwino kwambiri komanso ma abrasion komanso kuwonjezera mphamvu zamphamvu kwambiri.Misika yocheperako yomwe ingagwiritse ntchito izi ingakhale zachipale chofewa, kunyamula phukusi, kulongedza, kukonza chakudya ndi magalimoto.

Kulemera kwa mamolekyulu ndi komwe kumapatsa UHMW-PE kuphatikiza kwapadera kwamphamvu kwamphamvu kwamphamvu kwamakantha komanso kukana ma abrasion komwe kumaposa chitsulo cha kaboni 10 mpaka 1 kupangitsa kuti ikhale yoyenera kugwiritsa ntchito pomwe magiredi otsika a maselo amalephera.

Pali mayesero atatu omwe mungathe kuchita:

1. Kuwotcha Mayeso - kuyatsa ndi machesi ndikununkhiza utsi.Ngati amanunkhiza sera ya makandulo - izi zimasonyeza polyethylene.UHMW sitsika ngati HDPE koma imadontha.
2. Mayeso a Ovuni - ikani mu mbale ya aluminiyamu mu uvuni wa digiri 300.HDPE yokhazikika imatsika kapena kusungunuka koma UHMW sisintha kukula kapena mawonekedwe.Komabe, imatha kupotoza kapena kupotoza chifukwa cha kupsinjika komwe kumapangidwira.

Mayeso a Saw - Akadulidwa ndi macheka, HDPE yokhazikika imapereka utuchi kapena zosefera pomwe UHMW imapereka zingwe kapena ayi.
