UHMW Polyethylene Firimu ine yakanyanyisa abrasion kuramba, inodarika abrasion kuramba kwesimbi.Yakabatana nehupamhi hwemakemikari kuramba uye yakaderera coefficient yekukwesha inoita kuti UHMW ive inosarudzika yeinjiniya zvinhu kune akawanda akaomarara masevhisi ekushandisa.Inotsvedza kunge polymer® Fluoropolymer, asi super abrasion & inoshingirira kupfeka.UHMW Polymers ane huremu hwema molecular kanokwana gumi iyo yeakajairika high density polyethylene resin.Huremu hwemamorekuru hunopa UHMW Polymers musanganiswa wayo wakasiyana wehunhu Zvishandiso: Nzvimbo dzemukati nekunze dzemvura inonwiwa, kemikari, mafuta uye hydraulic hoses, nzvimbo dzepasi dzeskis nemapuranga echando, linings emachute kuderedza kukweshera nekupfeka.
Commercial skived film of ultra-high molecular-weight polyethylene (UHMWPE) ine high uniaxial orientation1 yakadzidzwa panguva yekunyunguduka uye crystallization ine nguva-resolution ye30 s kuitira kuti zvionekwe maitiro ekristallilization.
Yakawanikwa kuti isotropic crystallization inoitika pese apo kunyunguduka kunopisa kusvika ku140◦C kana pamusoro.Oriented crystallization inoitika, kana iyo yakanyunguduka ichichengetwa pa138◦C kana pazasi.Tembiricha yekunyungudika yakanyungudika inoita kunge 136◦C.Pane iyi tembiricha iyo semicrystalline nanostructure yefirimu yepakutanga inodzimwa zvachose, nepo ndangariro yekumisikidza yekunyunguduka inochengetedzwa.Uyezve, isothermal crystallization haigoni kutangwa pane tembiricha ye110◦C uye yakakwira.Pane tembiricha ye105◦C yakatarisana nekristaro inotanga mushure me2.5 min.Lamellae ane ukobvu hunodzikira zvishoma nezvishoma ari kukura panguva yekupisa kwemaminetsi makumi maviri.
Pakati peinotevera isiri-isothermal crystallization (inotonhora chiyero: 20◦C / min) zviduku zvekristalline zvidhinha zvine kuwirirana kwemuvakidzani kunoumbwa.Saka maitiro ekristallisation akafanana neaya anowanikwa aine mamwe ma polyethylene zvinhu zvine yakaringana yakakwirira cheni entanglement density yakadzidzwa kare, kunze kwekunyanya kutonhora kunodiwa kuti itange isothermal crystallization.
Kuongororwa kweiyo data munzvimbo chaiyo kuburikidza neiyo multidimensional CDF yakaitwa.Munguva yekunyunguduka kwezvinhu huwandu hwepakati hwemakristallini hunoramba huripo (27 nm), nepo nguva yakareba iri kuwedzera zvakasimba kubva pa60 nm kusvika 140 nm.Nokuti kuongorora kunoratidza kuti kunyange yepakutanga nanostructure inotongwa anotevera-muvakidzani correlations chete izvi zvinoreva kuti kugadzikana ari lamella ari monotonously kuwedzera sebasa chinhambwe kune vavakidzani vayo.Nepo chimiro chepakutanga chinoratidza yakawedzera lamellae, iyo recrystallised domains haina kureba kupfuura chinhambwe chiri pakati pawo mufiber direction s3.
Zvishandiso zvinosanganisira lining ye conveyor, njanji dzekutungamira, chute liner, cheni madhiraivha, dhirowa glide uye kuderedza ruzha.Yakanakisa abrasion uye kupfeka kuramba.
