Kub yaj nplaum nplaum granules
Granular kub yaj nplaum Thermoplastic Polyurethane (TPU) yog cov khoom siv ntau yam uas tau siv ntau hauv kev lag luam. TPU sib txuas cov khoom ntawm cov roj hmab thiab yas, thiab thaum nyob rau hauv daim ntawv granular rau kub - yaj daim ntaub ntawv, nws muaj tshwj xeeb zoo rau kev sib txuas cov ntaub ntawv sib txawv.
Kub yaj nplaum zaj duab xis ua lub luag haujlwm tseem ceeb hauv kev tsim cov lev, kom ntseeg tau tias cov khoom sib txawv ntawm cov lev tau ruaj khov. Lawv yog ib qho tseem ceeb hauv kev tsim cov ntaub ntawv ruaj khov, siab zoo rau ntau yam kev siv, los ntawm cov ntaub pua tsev hauv tsev thiab tsheb mus rau kev lag luam - siv cov ntaub pua tsev.
Kub yaj kua nplaum granules yog ib daim ntawv nrov ntawm cov nplaum uas muaj txoj hauv kev yooj yim thiab muaj txiaj ntsig rau kev sib txuas ntau yam ntaub ntawv. Lawv tau siv dav hauv kev lag luam xws li ntim khoom, ua haujlwm ntoo, textile, thiab hluav taws xob vim lawv yooj yim siv thiab ntau yam.
EVA yog lub hauv paus polymer rau kub yaj kua nplaum granules. Nws muab zoo yoog raws thiab adhesion. Cov ntsiab lus vinyl acetate tuaj yeem sib txawv, uas cuam tshuam rau cov khoom ntawm cov kua nplaum. Cov ntsiab lus vinyl acetate ntau dua feem ntau ua rau cov kua nplaum softer thiab tacky ntau dua, tsim nyog rau cov ntawv thov uas xav tau ib daim ntawv cog lus yooj yim dua, xws li hauv kev sib txuas ntawm cov yas los yog cov ntaub.
Daj kub yaj nplaum granules yog ib hom kub yaj nplaum nplaum uas sawv tawm vim lawv cov xim. Cov xim muaj peev xwm qee zaum qhia tau qee yam khoom lossis xav siv, thiab cov granules no muaj ntau yam kev siv hauv ntau yam lag luam xws li ntim khoom, khoom siv tes ua, thiab ua haujlwm ntoo.
Polyester kub yaj nplaum yog ib hom thermoplastic nplaum uas tau txais txiaj ntsig tseem ceeb hauv ntau qhov kev lag luam. Nws yog lub npe hu rau nws cov khoom sib txuas zoo heev, durability, thiab versatility.
Cov ntsiab lus tseem ceeb ntawm polyester kub yaj nplaum yog polyester cob. Nws yog synthesized los ntawm ib tug condensation cov tshuaj tiv thaiv ntawm dicarboxylic acids thiab diols. Kev xaiv ntawm dicarboxylic acids (xws li terephthalic acid) thiab diols (xws li ethylene glycol) tuaj yeem cuam tshuam cov khoom ntawm cov nplaum. Qhov hnyav molecular thiab cov qauv ntawm polyester resin ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab nws qhov melting point, viscosity, thiab daim ntawv cog lus lub zog.
