Kedu ihe kpatara uzuzu putty ji eme ka ọ dị gịrịgịrị ma gbakwunye mmiri?
A na-eji cellulose mee ihe dị ka onye na-ekpuchi mmiri na ihe na-ejide mmiri na putty. N'ihi thixotropy nke cellulose n'onwe ya, mgbakwunye nke cellulose na ntụ ntụ na-edugakwa na thixotropy mgbe agbakwunyere mmiri na putty.

Gịnị bụ ihe mere putty ji dị arọ na usoro scraping?
N'okwu a, viscosity nke cellulose a na-ejikarị eme ihe dị elu. Ụfọdụ ndị na-emepụta ihe na-eji cellulose 200,000 mee putty.
