1. cellulose ether - cellulose ether magabata
Cellulose ether shine mafi yawan polysaccharide a duniya a yau.Babban tushen cellulose na halitta shine auduga, bishiyoyi, tsire-tsire na ruwa, ciyawa da sauransu.Auduga ya ƙunshi 92-95% cellulose;Flax ya ƙunshi kusan 80% cellulose;Itace ta ƙunshi kusan 50% cellulose.
2, tsarin ether cellulose
Cellulose ether wani hadadden polysaccharide ne mai dauke da dubban raka'o'in glucose a cikin kwayoyin halitta, tsarin sinadaran shine (C6H10O5) N. Kungiyar D-glucose tana daure ta β-1,4 glucoside bonds.

Saka tsaka tsaki:
Depowder: rashin isasshen kayan siminti, cellulose ether riƙe ruwa bai isa ba, abun ciki na calcium mai nauyi yana da ƙasa.
Ayyukan gine-gine: haɓaka ta bentonite da sitaci ether.
ganga mara komai;Da kuma manne bangon da rashin isa ya haifar.
Layering: dubawa aiki.
Ƙarfi: Hakanan za'a iya daidaita shi ta hanyar grading calcium foda.
Calcium na lemun tsami:
Matsalolin su ne drum mara kyau, launin rawaya mai launin rawaya, ginin ba shi da kyau, depowder, stratification, cracking, bayan thickening;
Depowder: rashin isassun kayan siminti, rashin isasshen ruwa na cellulose ko ƙarancin adadin ƙari, ƙwayar lemun tsami ba ta da tsabta.
Rashin aikin gini mara kyau: bentonite da sitaci ether don ingantawa.
ganga mara komai;Kuma rashin isasshen mannewar bangon da ya haifar da ƙari mai dacewa na latex foda.
Layering: dubawa aiki.
Yellowing: zaɓi mara kyau na ether cellulose.
Cracking: Tushewar tushe ko ƙarfin tsagewa mai ƙarfi, shafi mai kauri sosai.
Bayan kauri: nauyin shayar ruwa mai nauyi ya bambanta, ana ba da shawarar zaɓin ruwan sha na sifili ko ƙananan foda mai nauyi;Calcium mai launin toka ya ƙunshi GaO mara narkewa.
Tushen siminti:
Matsaloli don drum mara kyau, ginin ba shi da kyau, depowder, delamination, fashe, rashin isasshen ruwa, coagulation na ƙarya;
Depowder: rashin isassun kayan siminti, rashin isasshen ruwa ether cellulose ko rashin isasshen adadin kari.
Rashin aikin gini mara kyau: bentonite da sitaci ether don ingantawa.
Drum mara kyau: da manne bangon da ya haifar da rashin isasshe, madaidaicin ƙari na latex foda.
Layering: dubawa aiki.
Yellowing: Zaɓin cellulose mara kyau.
Rashin isasshen ruwa: rashin isassun foda na latex da ƙarancin kayan siminti.
Cracking: fashewar tushe ko tsayin ƙarfi mai ƙarfi, shafi yana da kauri sosai, tare da putty don cika rami.
Ƙarya coagulation: Ana iya ƙara sodium gluconate don tsawanta lokacin aiki.
