Kev kuaj pom pom ua haujlwm yog ib kauj ruam tseem ceeb hauv kev ntsuam xyuas zoo rau cov cua fresheners, tsom mus rau cov khoom xim, tsw, lub cev lub cev, thiab ntim khoom. Rau cov kua cua fresheners, cov kua yuav tsum tau kuaj xyuas qhov tsis sib xws thiab tsis muaj kev sib cais, sedimentation, lossis impurities; rau gel-raws li cov khoom, kev ruaj ntseg ntawm cov qauv gel raug soj ntsuam. Tsis tas li ntawd, kev ntsuas kev hnov qab pab txiav txim siab seb cov tshuaj tsw qab puas yog ntuj thiab tsis muaj ntxhiab tsw phem, ua rau khaus, muab kev ntsuam xyuas thawj zaug ntawm cov khoom zoo.
Kev kuaj physicochemical suav nrog ntau yam xws li qib pH, kev ruaj ntseg, tsis muaj zog, thiab cov ntsiab lus nquag. Kev ntsuas pH tus nqi nrog cov cuab yeej tshaj lij qhia tau tias muaj kev ruaj ntseg ntawm cov qauv, thaum siab -kub, qis- kub, thiab ntev- lub sij hawm cia kev ntsuam xyuas pab xyuas cov cim ntawm cov khoom deterioration. Tsis tas li ntawd, simulating qhov kev siv tiag tiag ib puag ncig tso cai rau kev ntsuas ntawm cov tshuaj tsw qab tso tawm thiab lub sijhawm, ua kom muaj kev ntsuam xyuas ntawm cov khoom lag luam kev ua haujlwm tsis zoo thiab kev ua haujlwm zoo.
Hais txog kev nyab xeeb, huab cua fresheners feem ntau raug kuaj rau cov khoom siv tshwj xeeb, xws li volatile organic compound (VOC) qib, muaj cov khoom tsis zoo xws li formaldehyde, thiab cov ntsuas microbiological. Kev soj ntsuam ntawm cov tshuaj no txiav txim siab seb cov khoom puas ua tau raws li cov qauv kev nyab xeeb, yog li txo qis qhov cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv thiab ib puag ncig. Ntxiv mus, rau cov tsev neeg uas muaj cov pab pawg tsis muaj zog-xws li cov menyuam yaus thiab cov neeg laus- tshwj xeeb yog them rau cov khoom me me thiab kev nyab xeeb profile.
