Phonononga iimpawu ze-UHMWPE kunye nezicelo zayo eziNyezo
I-Polyethylene yeyona plastiki isetyenziswa kakhulu kwihlabathi, kodwa wazi njani ukuba ngumsonto ofanelekileyo kwisicelo sakho?Cinga ngeempawu ze-ultra-high-molecular-weight-polyethylene (UHMWPE) - i-subset enzima kakhulu ye-polyethylene enamandla obunzima bobunzima amaxesha angama-8-15 amakhulu kunentsimbi.
Eyaziwa kakhulu ngamagama orhwebo eSpectra® kunye neDyneema®, iiplastiki ze-UHMWPE kunye nemisonto zisetyenziselwa ikakhulu:
· Ukusetyenziswa kweBallistic (Isikrweqe soMzimba, ukuPlatyiswa kweSikrweqe)
· Imidlalo kunye nolonwabo (ukuntywila esibhakabhakeni, ukutyibiliza, ukutyibilika, ukuloba)
· Iintambo kunye neentambo
· Ukuphathwa kwezinto ezininzi
· Amalungu aneebhobhosi kunye nesihluzo
· Ushishino lweemoto
· Ishishini lemichiza
· Ukulungiswa kokutya kunye noomatshini bokusela
· Izixhobo zokwenziwa kwemigodi nezimbiwa
· Izixhobo zokuvelisa
· Ubunjineli bokwakha kunye nezixhobo zokushukuma komhlaba
· Usetyenziso olunxulumene nezothutho, kubandakanywa iitreyi zelori, imigqomo neehopper.
Njengokuba ubonaUHMWPEinoluhlu olwahlukeneyo lokusetyenziswa ukusuka kwimveliso ukuya kwezonyango kunye nocingo kunye nosetyenziso lwentambo.Oku kungenxa yoluhlu olude lwezibonelelo ezihlangabezana neemfuno ezithile zemisebenzi emininzi eyahlukeneyo.
Uncedo lwe-UHMWPE lubandakanya, kodwa aluphelelanga koku:
· Ukumelana okugqwesileyo kuxinzelelo kunye nokumelana okuphezulu nokuqhekeka
· Ukuxhatshazwa kwe-abrasion yokunxiba - amaxesha angama-15 axhathisa ngakumbi kwi-abrasion kune-carbon steel
· Inamandla ngama-40% kunemisonto ye-Aramid
· Ukumelana kwayo neekhemikhali olomeleleyo-yomelela kakhulu kwi-alkalis ezininzi kunye ne-asidi, izinyibilikisi zendalo, ii-agent zokuthoba kunye nohlaselo lwe-electrolytic.
· Ayinatyhefu
· Iipropati ezibalaseleyo zedielectric
· Ukuzithambisa – umlinganiso ophantsi kakhulu wokukhuhlana (uthelekiseka ne-PTFE)
· Ayinabala
· I-FDA ivunyiwe ukuba isetyenziswe ekutyeni nakwizicelo zonyango
· Umxhuzulane othile osezantsi – uya kudada emanzini
Ngelixa oku kunokuvakala ngathi yinto efanelekileyo, kukwakho nezinto ezingeloncedo ezimbalwa ekufuneka uzazi.I-UHMWPE inendawo esezantsi yokunyibilika (297° ukuya kuma-305° F) kuneepholima ezininzi eziqhelekileyo, ngoko ke ayifanelekanga ukusetyenziswa kobushushu obuphezulu.Ikwanayo ne-coefficient ephantsi ye-friction enokuthi ibe yi-drawback ngokuxhomekeke kwisicelo.Imisonto ye-UHMWPE inokuphuhlisa “ukurhubuluza” phantsi komthwalo ongaguqukiyo, nto leyo yinkqubo yokolulwa ngokuthe ngcembe kwemisonto.Abanye abantu banokuthatha ixabiso njengento engalunganga, nangona kunjalo xa kuziwa kwi-UHMWPE, ngaphantsi kungaphezulu.Ngenxa yokomelela kwesi sixhobo akufuneki uthenge kakhulu njengoko ubuya kwenza ngezinye izinto.
Usazibuza ukuba okanye hayiUHMWPEilungile kwimveliso yakho?Umsonto weNkonzo uphuhlisa kwaye uhambise imisonto yobunjineli kunye nemisonto yokuthunga ukusombulula iingxaki zemveliso kunye nokulungiswa kwabathengi bethu.Inkonzo esebenzayo, eyenzelwe wena ixhomekeke kuyo yonke into esiyenzayo.Qhagamshelana nathi ukufumanisa ukuba yeyiphi ifayibha eyona ilungileyo kwisicelo sakho.
