Contraindications ntawm Carboxymethyl Cellulose

Tom qab ua sodium carboxymethylcellulose rau hauv cov tshuaj aqueous, nws yog qhov zoo tshaj rau khaws cia rau hauv ceramic, iav, yas, ntoo, thiab lwm yam ntim. Cov thawv hlau, tshwj xeeb tshaj yog hlau, txhuas thiab tooj liab ntim, tsis haum rau kev khaws cia. Yog hais tias cov tshuaj aqueous ntawm sodium carboxymethyl cellulose nyob rau hauv kev sib cuag nrog hlau ntim rau lub sij hawm ntev, nws yuav ua rau deterioration thiab viscosity txo. Thaum lub aqueous tov ntawm sodium carboxymethyl cellulose yog tov nrog txhuas, Thaum hlau, tin, nyiaj, txhuas, tooj liab thiab tej yam hlau khoom coexist, ib tug deposition cov tshuaj tiv thaiv yuav tshwm sim, yog li txo qhov tseeb kom muaj nuj nqis thiab zoo ntawm sodium carboxymethylcellulose nyob rau hauv cov tshuaj.

Yog tias nws tsis yog rau kev tsim khoom, thov sim tsis txhob sib tov calcium, magnesium, ntsev thiab lwm yam tshuaj nyob rau hauv aqueous tov ntawm sodium carboxymethylcellulose, vim sodium carboxymethylcellulose tov coexists nrog calcium, magnesium, ntsev thiab lwm yam tshuaj, yog li carboxymethylcellulose viscosity ntawm lub sodium methylcellulose tov yuav txo.

Cov tshuaj sodium carboxymethyl cellulose aqueous muab yuav tsum tau siv kom sai li sai tau. Yog hais tias sodium carboxymethyl cellulose aqueous tov yog khaws cia rau lub sij hawm ntev, nws yuav tsis tsuas cuam tshuam rau adhesion muaj nuj nqi thiab stability ntawm sodium carboxymethyl cellulose, tab sis kuj yuav puas los ntawm cov kab mob thiab kab tsuag. , yog li cuam tshuam rau kev tu cov khoom zoo.
