CMC mubisanzwe anionmer polymer polymer yateguwe yo gufata selile karemano hamwe na aside ya alkali na aside ya monochlorondoace na monochlolorondoacetic hamwe nuburemere bwa molekiro bwa 6400 (± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 ± 1 Ibicuruzwa byingenzi nibicuruzwa ni sodium chloride na sodium glycolate. CMC ni iy'uburinganire busanzwe. Yiswe ku mugaragaro "yahinduwe na selile yahinduwe" n'ishami ry'Umuryango w'Abibumbye (FAO) n'umuryango w'ubuzima ku isi (NINDE).
ubuziranenge
Ibipimo ngenderwaho byo gupima ireme rya CMC ni urwego rwo gusimbuza (DS) kandi rwuzuye. Mubisanzwe, imitungo ya CMC iratandukanye iyo DS itandukanye; Urwego rwo hejuru rwo gusimbuza, nibyiza kudusaba, nibyiza gukorera mucyo no gutuza kubisubizo. Nk'uko amakuru abitangaza, gukorera mu mucyo bya CMC nibyiza mugihe urwego rwo gusimburwa ari 0.7-1.2, kandi virusi yikibazo cyacyo nicyo kinini mugihe agaciro cya PH ni 6-9. Kugirango tumenye neza, hiyongereyeho guhitamo umukozi ushimishije, ibintu bimwe bigira ingaruka ku rwego rwo gusimburwa no kweza bigomba gusuzumwa, igihe cyo guhoberana, ubushyuhe, ubushyuhe, ubushyuhe bwa sisitemu, igisubizo.
Isesengura ryibyiza nibibi bya sodium carboxymethyl selile
Iterambere rya sodium Carboxymethyl selile rwose ntabwo itigeze ribaho. Cyane cyane mumyaka yashize, kwagura ibisabwa no kugabanya ibiciro byumusaruro byatumye gukora karboxymethyl selile selile kandi ikunzwe cyane. Ibicuruzwa bigurishwa bivanze.
Noneho, uburyo bwo kumenya ubwiza bwa sodium carboxymethyl selile, turasesengura mubitekerezo bimwe byumubiri nuburozi:
Mbere ya byose, birashobora gutandukanywa nubushyuhe bwa karubone. Ubushyuhe bwa karubone ya sodium carboxymethyll selile ni 280-300 ° C. Iyo karumeke mbere yuko ubu bushyuhe bugerwaho, noneho ibicuruzwa bifite ibibazo. (Mubisanzwe karuboni ikoresha itanura rya muffle)
Icya kabiri, itandukanijwe nubushyuhe bwo gukumira. Mubisanzwe, sodium carboxymethyl selile izahindura ibara iyo igeze ku bushyuhe runaka. Ubushyuhe buri myaka 190-200 ° C.
Icya gatatu, irashobora kumenyekana kubigaragara. Kugaragara kw'ibicuruzwa byinshi ni ifu yera, kandi ingano yacyo muri rusange ni mesh 100, kandi amahirwe yo kunyura ni 98.5%.
Sodium carboxymethyl selile ni ibicuruzwa byakoreshejwe cyane kandi bifite ibyifuzo byinshi, bityo hashobora kubaho kwigana ku isoko. Nigute rero wamenya niba ari umusaruro usabwa nabakoresha ushobora gutsinda ikizamini kiranga.
Choose 0.5g of sodium carboxymethyl cellulose, which is not sure whether it is a product of sodium carboxymethylcellulose, dissolve it in 50mL of water and stir, add a small amount each time, stir at 60 ~ 70 ℃, and heat for 20 minutes to make a uniform solution, cool After the liquid detection, the following tests were carried out.
1. Ongeraho amazi kubizamini byibizamini inshuro 5, ongeraho 0.5ml ya aside ya chrontropic igisubizo kuri 1 igitonyanga 1, kandi ubushyure mu bwogero bwamazi muminota 10 kugirango ugaragare umutuku.
2. Ongeramo ML 10 ya Acetone kugeza 5 ML yikizamini, Shake hanyuma uvange neza kugirango utange neza flocculent.
3. Ongeramo 1ml ya ketone sulfate igisubizo kuri 5ml yigisubizo cyibizamini, kuvanga no guhanagura kugirango utange urumuri rwubururu.
4. Ibisigisigi byabonetse ku nkombe yibi bicuruzwa byerekana reaction isanzwe ya sodium umunyu, ni ukuvuga, sodium carboxymethyl selile.
Binyuze muri izi ntambwe, urashobora kumenya niba ibicuruzwa byaguzwe sodium carboxymethyl selile ya selile kandi itunganijwe, itanga uburyo bworoshye kandi bufatika kubakoresha neza
