UHMWPE yog dab tsi? Vim li cas thiaj siv UHMWPE hauv Smartkool® Fabric?
Ultra-High Molecular Nyhav Polyethylene (UHMWPE) yog odorless, tasteless, thiab nontoxic.Nws yog thawj polymerized nyob rau hauv 1950's. Thawj Ultra-High Molecular Nyhav Polyethylene (UHMWPE) fibers tau ua lag luam nyob rau xyoo 1970's. Nws muaj cov hlua ntev heev ntawm polyethylene, uas txhua qhov sib npaug hauv tib qho kev taw qhia. Nws cov molecular loj yog mus txog 3.5-7.5million amu, uas yog siab tshaj polyester yarn nrog ib tug molecular mass txog 20000.Thaum siv nyob rau hauv fibers, cov polymer chains tau ib tug parallel orientation ntau dua 95 feem pua thiab ib theem ntawm crystallinity los ntawm 39 feem pua rau 75 feem pua.
Nrog cov qauv molecular yooj yim, UHMWPE muaj qee qhov chaw thiab cov khoom siv tshuaj lom neeg uas tsis tshua pom muaj nyob hauv lwm cov polymers ua haujlwm siab. Piv txwv li, Vim tias nws cov olefins tsis muaj pawg polar, UHMWPE tsis nqus dej yooj yim, los yog ya raws yooj yim. Qhov no kuj ua rau nws txuas mus rau lwm cov polymers nyuaj. Rau tib lub laj thawj, daim tawv nqaij tsis cuam tshuam nrog nws, yog li UHMWPE fiber ntau yog nplua heev. Txij li thaum UHMWPE tsis muaj tshuaj lom neeg (xws li esters, amides lossis hydroxylic pawg), nws tiv taus dej, noo noo, tshuaj lom neeg feem ntau, UV hluav taws xob, thiab cov kab mob microorganisms.
Nrog qib siab ntawm crystallinity thiab molecular mass, UHMWPE yarn muaj qhov kub thiab txias conductivity, uas tuaj yeem hloov cov cua sov sai thiab paub txog cov nyhuv txias txias. Featuring tiv thaiv dej, noo noo, tshuaj lom neeg feem ntau, UV hluav taws xob, thiab cov kab mob microorganisms, UHMWPE fiber ntau muab kev tiv thaiv rau koj.
