1. cellulose ether - cellulose ether ụzọ
Cellulose ether bụ polysaccharide kasị ukwuu n'ụwa taa.Isi mmalite nke cellulose eke bụ owu, osisi, osisi mmiri, ahịhịa na ihe ndị ọzọ.Owu nwere 92-95% cellulose;Flax nwere ihe dịka 80% cellulose;Osisi nwere ihe dịka 50% cellulose.
2, cellulose ether Ọdịdị
Cellulose ether bụ polysaccharide dị mgbagwoju anya nwere ọtụtụ puku nkeji glucose na molekul, usoro kemịkalụ bụ (C6H10O5) N. A na-ejikọta otu D-glucose site na β-1,4 glucoside bonds.

Putty na-anọpụ iche:
Depowder: ihe simenti na-ezughị ezu, cellulose ether mmiri na-ejide ezughị, ọdịnaya calcium nke calcium dị arọ dị ala.
Ịrụ ọrụ ihe owuwu: emelitere site na bentonite na starch ether.
Ịgba ihe efu;Na mgbidi adhesion kpatara ezughị oke.
Layering: interface nhazi.
Ike: Enwere ike gbanwee site na grading calcium ntụ ntụ.
Uru nke calcium lime:
Nsogbu ndị na-efu drum, depowder yellowing, ewu adịghị mma, depowder, stratification, cracking, mgbe ndim;
Depowder: ihe simenti na-ezughị ezu, ezughị oke mmiri nke cellulose ma ọ bụ ezughị oke nke mgbakwunye, calcium lime adịghị ọcha.
Ọrụ owuwu na-adịghị mma: bentonite na starch ether iji meziwanye.
Ịgba ihe efu;Na ezughị ezu nrapado mgbidi mere site kwesịrị ekwesị mgbakwunye nke latex ntụ ntụ.
Layering: interface nhazi.
Yellowing: nhọrọ na-ekwesịghị ekwesị nke cellulose ether.
Mgbawa: mgbawa ntọala ma ọ bụ ike mgbawa siri ike, mkpuchi oke oke.
Mgbe ịgbara: oke mmiri mmiri calcium dị arọ dị iche iche, a na-atụ aro ka ịhọrọ ntinye mmiri efu ma ọ bụ ntụ ntụ calcium dị ala;Calcium isi awọ nwere GaO enweghị mgbari.
Putty dabeere na ciment:
Nsogbu maka drum efu, ihe owuwu adịghị mma, depowder, delamination, cracking, ezughị oke mmiri na-eguzogide, ụgha coagulation;
Depowder: ihe simenti na-ezughị ezu, ezughị ezu cellulose ether njide mmiri ma ọ bụ ezughị oke nke mgbakwunye.
Ọrụ owuwu na-adịghị mma: bentonite na starch ether iji meziwanye.
Ịgba ihe efu: na nrapagide na mgbidi nke ezughị oke, mgbakwunye ezi uche dị na ya nke ntụ ntụ latex.
Layering: interface nhazi.
Yellowing: Nhọrọ cellulose na-ezighi ezi.
Enweghị oke mmiri na-eguzogide: uzuzu latex ezughi oke na ihe cimenti zuru oke.
Mgbawa: mgbawa ntọala ma ọ bụ oke ike mgbawa, mkpuchi dị oke oke, na putty iji mejupụta oghere ahụ.
Ụgha coagulation: sodium gluconate nwere ike ịgbakwunye ogologo oge ọrụ.
