CMC inowanzo kuve yeAnonic Polymer Yakagadzirirwa nekuita zvakasikwa cellulose ine Caustic Alkali uye monochlorocacic acid, ine monoculero ye6400 (± 1 000). Iyo mainini-zvigadzirwa ndee sodium chloride uye sodium glycolate. CMC ndeyavo yemasikirwo cellulose shanduko. Iyo yakadanwa zviri pamutemo
mhando
Iyo Main Zviratidzo kuyera mhando yeCMC ndiyo mwero wekutsiva (DS) uye kuchena. Kazhinji, zvivakwa zveCMC zvakasiyana kana DV zvakasiyana; Iyo yakakwira iyo degree rekutsiva, iri nani solubility, uye zviri nani pachena uye kugadzikana kwemhinduro. Sekureva kwemishumo, iyo transparcy yeCMC iri nani kana iyo degree rekutsiva iri 0.7-1.2, uye zvikwangwani zvemukati zvemukati mhinduro ndiyo yakakura kana iyo PH kukosha ndeye 6-9. Kuti uve nechokwadi chekuwedzera kunaka, kuwedzera kusarudzo kwekunyepedzera mumiririri wekutsiva uye nekuchena kunofanirwa kuve neyakagadziriswa, yakadai, system yemvura, tembiricha, mhinduro.
Kuongororwa kwezvakanakira uye zvakashata zve sodium carboxymeym cellulose
Iko kuvandudzwa kwesodium carboxymethyl cellelose haina kumbobvira yamboitika. Kunyanya mumakore achangopfuura, kuwedzera kweminda yekushandisa uye kuderedzwa kwemitengo yekugadzira yakaita kuti mugadziri weCarboxyMethyl Cellevose more uye zvakanyanya kufarirwa. Zvigadzirwa zviri kutengeswa zvakasanganiswa.
Zvadaro, maitiro ekuziva kunaka kweiyo sodium carboxymeym cellever, isu tinoongorora kubva kune mamwe maitiro emuviri uye nemakemikari:
Chekutanga pane zvese, inogona kusiyaniswa kubva pakudziya kabhoni. The general carbonization temperature of sodium carboxymethyl cellulose is 280-300 ° C. When it is carbonized before this temperature is reached, then this product has problems. (Kazhinji carbonization inoshandisa muffle muchoto)
Kechipiri, inosiyaniswa nekudziya kwaro kudziya. Kazhinji, sodium carboxymethyl cellelose ichachinja ruvara kana ichisvika kune imwe tembiricha. Iyo tembiricha yakasviba ndeye 190-200 ° C.
Yetatu, inogona kuzivikanwa kubva pakuonekwa kwayo. Kuonekwa kwezvigadzirwa zvakawanda ndeye chena poda, uye hukuru hwayo hwevhu hunowanzosvitsa zana mesh, uye mukana wekupfuura kuburikidza ne98,5%.
Sodium carboxymethyl cellelose inoshandiswa zvakanyanya cellulose chigadzirwa uye ine huwandu hwakawanda hwekushandisa, saka panogona kunge paine kutevedzera pamusika. Saka maitiro ekuziva kuti ichi chigadzirwa chinodiwa nevashandisi vanogona kupfuudza bvunzo inotevera yekuzivikanwa.
Sarudza 0.5g yeSodium CarboxyMeym Cellemelle, isishuve ihwohwo chigadzirwa cheSodium nguva imwe neimwe, chimhanya kwemaminitsi makumi maviri kuti ugone kuongororwa, kutonhorera kwekuonekwa kwemvura, kutonhora kwekuwanikwa kwemvura, iyo miedzo inotevera yakaitwa.

2. Wedzera 10 mL yeAcetone kusvika ku5 ml yeiyo bvunzo mhinduro, zunza uye sanganisa zvakakwana kuti uburitse chena flipitate.

Kuburikidza nematanho aya, iwe unogona kuziva kuti chigadzirwa chakatengwa is sodium carboxymelmelose uye kuchena kwayo, iyo inopa nzira iri nyore uye inoshanda kune vashandisi kusarudza zvigadzirwa nenzira kwayo
