Teb chaws Europe, Tebchaws Asmeskas, Nyiv thiab lwm lub tebchaws tsim kev lag luam muaj keeb kwm ntev ntawm kev tsim thiab siv cellulose ethers, nrog cov cuab yeej siv siab heev thiab ua rau kev tsim cov cellulose ether daim ntaub ntawv. Cov kev qhia ntawm qee cov khoom ntawm cov tuam txhab loj hauv tebchaws tau mus txog cov qauv ntawm cov khoom zoo sib xws ntawm cov tuam txhab muaj npe nrov thoob ntiaj teb, tab sis tseem muaj qee qhov sib txawv ntawm kev tshawb fawb thiab kev tsim kho thev naus laus zis thiab qib siab thoob ntiaj teb.
Tam sim no, cov txheej txheem tseem ceeb ntawm cov cellulose ethers suav nrog cov txheej txheem roj theem thiab cov txheej txheem ua kua theem. Cov tuam txhab muaj npe nrov hauv cov teb chaws tsim kho feem ntau siv cov txheej txheem roj theem, thaum cov lag luam hauv tsev feem ntau siv cov txheej txheem ua kua theem. Cov roj theem txoj kev muaj qhov zoo ntawm lub sijhawm luv luv, muaj peev xwm ntau lawm, tsis siv cov kuab tshuaj, tus nqi qis thiab kev siv lub zog, tab sis qhov kev hloov kho thiab kev hloov pauv ntawm cov kab ntau lawm tsis zoo dua li cov txheej txheem ua kua; cov tshuaj tiv thaiv uniformity, adjustability thiab yooj ntawm cov kua theem txoj kev yog zoo dua li cov roj theem txoj kev, tab sis tus nqi thiab lub zog noj yog kuj siab.
