Chemists ntawm University of Reading nyob rau hauv UK, koom tes nrog Domino Printing Sciences, tau tsim ib tug tshiab polyurethane nplaum uas huv si tshem tawm cov ntawv. Cov nplaum no pab tsim cov khoom zoo dua - cov yas zoo dua qub. Adhesives siv los txuas cov ntawv rau lub raj mis yas feem ntau tawm cov khoom seem, txwv cov kev xaiv rov ua dua tshiab. Cov nplaum polymer tshiab no tawg thaum kho nrog alkali. Thaum cov ntawv lo yuav lo rau lub raj mis thaum siv ib txwm siv, lawv tau yooj yim tshem tawm nrog rau cov nplaum thaum rov ua dua. Cov nplaum polyurethane no muaj sulfonyl ethyl carbamate ua cov saw txuas ntxiv, uas tau hais los ua cov tshuaj hloov pauv thaum raug rau qee yam tshuaj, suav nrog alkalis. Hauv kev sim, kev kho ntawm cov nplaum polyurethane no nrog cov tshuaj tetrabutylammonium fluoride ua rau lub cev puas tsuaj ntawm cov saw txuas, ua rau nws poob ob -feem peb ntawm nws cov adhesion ntawm ntau qhov chaw sib txawv. Kev ntsuam xyuas tau pom tias cov nplaum polyurethane tshiab no tuav lub zog txaus ntawm iav thiab txhuas qhov chaw ntawm qhov kub thiab txias, ua rau nws haum rau ntau yam kev siv, nrog rau cov ntim khoom noj, ntim khoom, thiab khoom siv hluav taws xob. Los ntawm kev ua kom yooj yim cais cov khoom sib txawv thaum lub sij hawm rov ua dua tshiab, cov khoom siv rov ua dua tshiab tuaj yeem txhim kho tau zoo. Qhov no tuaj yeem txo cov khoom pov tseg uas xaus rau hauv qhov chaw pov tseg.
