HPMC pobzeb nplaum, tuav dej zoo

Ordinary pobzeb nplaum yog tsim rau cov vuas hauv pem teb los yog cov phab ntsa me me nrog rau cov pob zeb zoo tib yam. Nws raug nquahu kom siv high-viscosity hydroxypropyl methylcellulose (HPMC) rau cov nplais nplaum, thiab qhov ntau npaum li cas yog li 0.2-0.3% hauv mortar qhuav.
