DuPont Paper yog dab tsi?
Lub npe hu ua "DuPont paper" hauv kev ua lag luam yog ob yam khoom tsim los ntawm DuPont: ib qho yog cov khoom siv polyethylene high-density, hu ua Tyvek, thiab Suav lub npe yog Tyvek; lwm yam yog meta-aramid fiber ntau, Lub npe yog Nomex, thiab Suav lub npe yog Nomex.
Tyvek tau tsim nyob rau xyoo 1950 thiab ua lag luam nyob rau xyoo 1960. Tyvek yog polyethylene high-density polyethylene ua los ntawm high-density polyethylene siv flash evaporation technology, uas yog ua tiav los ntawm kub-melting polymer rau hauv nruam filaments thiab ces thermally bonded. Cov txheej txheem tshwj xeeb no tso cai rau Tyvek sib txuas cov ntawv, zaj duab xis thiab ntaub. Tag nrho hauv ib qho khoom siv, tsis muaj dej, breathable, hnav, muaj zog, tsim kua muag-resistant, puncture-resistant, siab reflectivity, diffuse reflectance, UV-resistant, tshwj xeeb zoo nkauj thiab kov, ib puag ncig tus phooj ywg, recyclable, thiab sib xws nrog ntau yam luam ntawv technologies Thiab feem ntau digital printing technology, haum rau ntau yam kev siv tshuab. Tyvek yog siv dav hauv cov ntaub ntawv tsis muaj dej thiab ua pa rau sab nrauv phab ntsa thiab lub ru tsev, cov ntaub ntawv ntim khoom kom tsis muaj menyuam rau cov khoom siv kho mob, thiab tshuaj tiv thaiv khaub ncaws hauv kev lag luam kev tiv thaiv tus kheej. Nyob rau hauv xyoo tas los no, Tyvek kuj tau pom nyob rau hauv ntau yam pej xeem tsim thiab cov khoom muaj tswv yim, xws li cov khoom siv hauv tsev, zam, kos duab, kab lis kev cai thiab cov khoom muaj tswv yim, kev tiv thaiv ib puag ncig thiab kev ntim khoom muaj tswv yim, thiab lwm yam. Tyvek yog dawb huv thiab tuaj nyob rau hauv ob qho kev tsim kho. : Cov khoom siv tawv tawv zoo li ntawv thiab cov khoom siv mos zoo li daim ntaub.
Raws li cov khoom siv insulating, Nomex tau siv dav hauv ntau yam khoom siv hluav taws xob thiab hluav taws xob uas ua tau raws li UL, IEC thiab ntau lub teb chaws thiab cov qauv hauv cheeb tsam, xws li hluav taws xob rwb thaiv tsev ntawm cov motors, transformers, cov khoom siv hauv tsev, cov cuab yeej hluav taws xob thiab cov khoom siv HVAC me me.
