Into malunga ne-UHMW onokufuna ukuyazi

I-UHMW-PE imele i-Ultra High Molecular Weight Polyethylene.Yeyona polyethylene (PE) yomgangatho ophezulu ekhoyo, yenzelwe imisebenzi enzima kunye noluhlu olubanzi lwezicelo.

Inikezela ngolondolozo kwinani lezicelo ezinzima.I-Ultra High Molecular Weight yimfihlelo yale mpawu ikhethekileyo yepolymer.I-resin yayo ephezulu ye-polyethylene ine-molecular weight range ye-3 ukuya kwi-6 yezigidi, xa kuthelekiswa ne-300,000 ukuya kwi-500,000 ye-high molecular weight (HMW) resins.Loo mahluko yintoni eqinisekisa ukuba esi sixhobo sinamandla ngokwaneleyo ukuba simelane ne-abrasion kunye nempembelelo engcono kuneemveliso zepoly ezisezantsi.Ubunzima bemolekyuli obuphezulu be-UHMW-PE buthetha ukuba abuyi kunyibilika okanye buhambe njengolwelo olunyibilikisiweyo.Iindlela zokucutshungulwa ke ngoko zisuka kwezo zeteknoloji yentsimbi yomgubo.I-UHMW-PE ayinakuguqulwa kwaye ibunjwe ngobuchule obuqhelekileyo bokucutshungulwa kweplastiki (i-injection yokubumba, ukubunjwa kokuvuthela okanye i-thermoforming).Ukubumba ukunyanzeliswa yeyona nkqubo ixhaphakileyo yokuguqula isetyenziswa nale resin kuba ivelisa imveliso eyomeleleyo, engaguqukiyo.

I-UHMW yaziwa ngokuxhathisa kwayo kwi-abrasion ephezulu, ukuthambisa kwendalo, amandla empembelelo ephezulu, ikhemikhali-, i-corrosion-, kunye nokuxhathisa ukufuma kunye ne-acoustic impedance.

Ngenxa ye-abrasion-, i-corrosion-, chemical-resistant-resistant properties, i-UHMW iqhele ukusetyenziswa kwizicelo apho iimeko zinokuba nzima kakhulu kwezinye izinto.Yipolymer esebenzayo eneendleko eziphezulu ezisetyenziselwa ukuvelisa ixabiso eliphantsi, iindawo eziphezulu.

I-UHMW sisixhobo sokuzithambisa esibonisa ukunxiba okugqwesileyo kunye neempawu zokuqhawuka kunye nokongeza amandla anempembelelo ephezulu kakhulu.Iimarike ezimbalwa ezinokuthi zisebenzise ezi mpawu ziya kuba ziibhodi zesnowboard, ukuphatha iphakheji, ukupakishwa, ukulungiswa kokutya kunye nemoto.

Ubunzima bemolekyuli obuphezulu buyinto enika i-UHMW-PE indibaniselwano ekhethekileyo yamandla aphezulu efuthe elisebenzayo lokukhuhlana kunye nokuxhatshazwa kwe-abrasion ekhupha i-carbon steel 10 kwi-1 eyenza ukuba ifaneleke ngakumbi kwizicelo apho amabakala aphantsi obunzima be-molecular ahluleka.

Kukho iimvavanyo ezintathu onokuzenza:

1. Tshisa uvavanyo - lukhanyise ngomcinga kwaye unukise umsi.Ukuba ivumba njenge-wax yekhandlela - oko kubonisa i-polyethylene.I-UHMW ayivuzi ngokulula njenge-HDPE kodwa iya kuthontsiza.
2. Uvavanyo lwe-oven - lubeke kwisitya se-aluminium kwi-oven ye-300 degree.I-HDPE eqhelekileyo iya kudilika okanye inyibilike kodwa i-UHMW ayiyi kutshintsha ubungakanani okanye imilo.Nangona kunjalo, inokuthi ijike okanye ijike ngenxa yoxinzelelo olwakhiweyo.

Uvavanyo lweSaw - Xa usikwa ngesarha, i-HDPE eqhelekileyo inika i-sawdust okanye iifayili ngelixa i-UHMW inika iintambo okanye akukho nto.
