A cikin wata takarda da aka buga a wannan makon a cikin Physics of Fluids, na AIP Publishing, Alexander Yarin da abokan aikinsa sun gano cewa ƙarfin kayan aiki mai faɗakarwa ko likitan haƙori bai dace da abubuwan da ke amfani da viscoelastic na polymer-abinci ba, kamar su polyacrylic acid, wanda sun yi amfani dashi azaman ƙaramin haɗuwa don shayarwa a cikin saitunan haƙori.

Sakamakonsu ya kasance abin mamaki. Ba wai kawai karamin karamin hade-hade na polymers ya kawar da gyaran fuska ba, amma ya yi hakan ne cikin sauki, yana nuna kimiyyar kere-kere ta polymer, irin su sauya-juyawa, wanda ya yi amfani da manufar da kyau.

Sun gwada polymer guda biyu da FDA ta amince da su. Polyacrylic acid ya tabbatar da inganci fiye da danko xanthan, domin banda yawan danko mai tsawan elongation (matsin lamba na mai saurin mikewa), ya bayyana wani dan karamin karfi mai yankar shege, wanda yake sa yin famfo shi da sauki.

Yarin ya ce "Abin ban mamaki shi ne cewa gwaji na farko a dakin gwaje-gwaje ya tabbatar da batun," “Abin mamaki ne yadda waɗannan kayan suka kasance masu iya sauƙaƙawa kuma suka hana aerosolization ta kayan aikin haƙori, tare da mahimman tasirin rashin ƙarfi. Amma duk da haka, karfin robar da aka samar ta hanyar kananan polymer additives sun fi karfi. ”

Binciken su ya yi bayanin tashin hankalin aljihun ruwan da aka bayar ga hakora da cingam wanda kayan aikin hakori ke motsawa. Hazo mai feshin ruwa wanda ke tare da ziyarar likitan hakora sakamakon ruwa ne da ya gamu da saurin jijiyar kayan aiki ko karfin tsaka-tsakin bita, wanda ke fasa ruwa a cikin kananan diga-dugai kuma yake tunkuda su.

Gwanin polymer, lokacin amfani dashi don ban ruwa, yana danne fashewar abubuwa; maimakon haka, polymer macromolecules masu shimfidawa kamar zaren roba suna hana aerosolization na ruwa. Lokacin da tip na kayan aikin jijjiga ko hakoran haƙori ya afka cikin maganin polymer, zaren maganin ya zama cikin igiyoyin snakelike, waɗanda aka ja da baya zuwa ƙarshen kayan aikin, suna canza abubuwan da aka saba gani da ruwa mai tsabta a cikin likitan hakora.

“Lokacin da digon ruwa ke kokarin ballewa daga jikin ruwa, sai a fadada wutsiyar dusar. A nan ne muhimmin karfi na roba da ke hade da jujjuyawar halittar polymer macromolecules za su yi wasa, ”in ji Yarin. "Suna danne yaduwar jela da kuma jan digon bayan, gaba daya suna hana aerosolization."
