Hydroxypylththththththylcelllose (hpmc)bụ nke na-abụghị nke ionic sel celluse nke ọtụtụ ebe eji arụ ọrụ, ọkachasị na usoro nke ihe ndị dabeere ciment. Ọrụ ya bụ isi ọrụ gụnyere ndozi mmiri, ihe na-eme ihe na ihe owuwu nke ihe ahụ ma mee ka akụrụngwa rụọ ọrụ nke ihe ahụ.
1. Mmelite nke Nnọchi Anya
HPMC nwere ezigbo nnabata mmiri. Na ihe ndị dabeere ciment, mfu nke mmiri nwere ike imetụta mmeghachi omume hydration nke ciment, na-eduga n'ike na-enweghị ike, nsogbu na nsogbu ndị ọzọ dị mma. HPMC nwere ike igbochi oke mmiri site na ịmepụta polymen polymer dị n'ime ihe ahụ, si otú a na-agbawa oge mmeghachi omume ciment hyderation oge. Arụmọrụ eji mmiri a dị ezigbo mkpa na elu okpomọkụ ma ọ bụ gburugburu akọrọ, ma nwee ike imeziwanye owuwe ihe owuwu, ihe na ihe ndị ọzọ.
2. Meziwanye ihe owuwu na oru
HPMC bụ ihe dị mma. Dinggbakwunye obere ego HPMC ruo na ihe ndị dabeere na ciment nwere ike ịbawanye vist na viscosity nke ihe ahụ. Nketu-enyere aka gbochie sluramiting, ịba ume ma ọ bụ ọbara ọgbụgba n'oge, mgbe ị na - eme ihe ahụ mfe ịgbasa na ọkwa. Na mgbakwunye, HPMC na-enye ihe adhesion siri ike, na-eme ka ngwakọta nke ngwa agha ahụ, ma na -ebelata ihe mkpofu n'oge owuwu.
3. Ndozi nke nguzogide
Ihe ndị sitere na ciment na-adịkarị mfe ịmịsa n'ihi mmiri mmiri na olu dị egwu n'oge usoro ịgbachi ụkwụ. Ngwongwo mmiri nke HPMC nwere ike ịgbakwunye usoro plastik nke ihe ahụ ma belata ihe ize ndụ nke cracks na-agbada. Na mgbakwunye, HPMC na-akụzisị nchegbu n'ime site na ịbawanye ikike nke na-enweghị njikọ na ihe omume ahụ, na-ebelata ihe omume nke cracks. Nke a bụ ihe dị oke mkpa maka ngwa ngwa oyi oyiri na nke na-enweghị ihe.

Na gburugburu ya oyi, nguzogide nke ihe metụtara ndụ na ndụ ọrụ ha. HPMC na-agbada mmebi nke ihe ndị sitere na ciment n'oge ifo na-eme ihe ma na-eme ka ahụ ha dịkwuo mfe ma na-eme ka ha nwekwuo ike.
5. Ewelite ngwa ngwa Njirimara
Ọ bụ ezie na isi ọrụ nke HPMC bụ ịbawanye ike ozugbo, ọ na-eme ka ihe ndị mebere ngwaọrụ ciment. Site na njigide mmiri na ọrụ ike, HPMC na-atụkwa ciment nke ọma ma na-etolite ngwaahịa ngwa ngwa dender, si otú ahụ na-eme ka ihe onwunwe na ike na-eme ka ihe na-eme ka ọ dịkwuo mma. Na mgbakwunye, ezigbo ọrụ na njikọta njikọta njikọta na-enyere aka belata ntụpọ nke owuwu, si otú a na-eme ka ọ dịkwuo usoro arụmọrụ nke ihe ahụ.
6. Ihe atụ
