HPMC nwere ike gbanwee ọnụ ọgụgụ mmiri evaporation nke ngwaahịa sitere na ciment iji belata ihe omume nke mgbape. Site n'ịgbanwe usoro hydration nke ngwaahịa ndị sitere na ciment, HPMC nwere ike belata mgbawa nke ọma site na ọdịiche okpomọkụ, mgbanwe iru mmiri ma ọ bụ nrụgide dị n'ime nke ngwaahịa sitere na ciment n'onwe ya, si otú ahụ na-eme ka ọ dịkwuo ogologo oge nke ngwaahịa ahụ.
5. Kwalite mgbochi ụfụfụ na nkwụsi ike
HPMC nwere ike ijikwa ọdịnaya afụ nke ọma na ngwaahịa simenti ma kwalite njirimara mgbochi ụfụfụ ha. Ihe omume nke afụ na ngwaahịa ndị dabeere na ciment ga-emetụta ike, mgbagwoju anya na ọdịdị nke ihe. Mgbakwunye nke HPMC nwere ike ime ka usoro nke slurry kwụsie ike ma belata ọgbọ nke egosipụta, si otú a na-eme ka kọmpat na arụmọrụ zuru ezu nke ngwaahịa ahụ dịkwuo mma.
6. Mma elu ire ụtọ na ọdịdị
N'ọtụtụ ngwaahịa ndị sitere na ciment, ịdị mma elu na ọdịdị ọdịdị nwere mmetụta dị mkpa na asọmpi ahịa nke ngwaahịa ikpeazụ. HPMC nwere ike imeziwanye mmiri nke ngwaahịa ndị sitere na ciment, mee ka elu ha dị nro ma dị nro, ma belata ntụpọ dị ka peeling na afụ n'oge a na-ewu ụlọ, si otú a na-eme ka ọdịdị nke ngwaahịa ahụ dịkwuo mma. Karịsịa n'ime ngwa ndị dị ka mkpuchi na mkpuchi tile, HPMC nwere ike hụ na elu ahụ enweghị ntụpọ ma nweta mmetụta ọhụụ ka mma.
7. Meziwanye mgbanwe na mgbanwe
HPMC bụ ihe enwere ike ịhazi ya na mkpa dị iche iche. Site na-agbanwe agbanwe ya molekụla Ọdịdị (dị ka dị iche iche degrees nke hydroxypropylation, methylation, wdg), na ndim arụmọrụ, solubility, egbu oge mwube oge na ndị ọzọ e ji mara HPMC nwere ike gbanwee, si otú na-enye customization maka dị iche iche nke ciment dabeere na ngwaahịa. ngwọta. Dịka ọmụmaatụ, maka nrapado tile na-arụ ọrụ dị elu na nrụzi ngwa agha, ụdị HPMC dị iche iche nwere ike iji gboo mkpa ihe owuwu dị iche iche.
8. Kwalite nchedo gburugburu ebe obibi na nchekwa ike
Dịka ihe eji eme polymer eke, HPMC anaghị adị egbu egbu, adịghị emerụ ahụ ma na-egbo mkpa nchekwa gburugburu ebe obibi. Iji ngwaahịa simenti nke HPMC na-eme ọ bụghị naanị na ọ na-eme ka arụmọrụ ụlọ dịkwuo mma, kamakwa ọ na-ebelata mmetụta ọjọọ na gburugburu ebe obibi. Na mgbakwunye, mgbakwunye nke HPMC nwere ike belata ọnụ ahịa ciment nke ọma, chekwaa ike, ma nyere aka melite arụmọrụ ogologo oge nke ngwaahịa sitere na ciment ma belata ụgwọ ọrụ.
9. Melite nkwụsi ike okpomọkụ
HPMC nwere ụfọdụ nkwụsi ike na-ekpo ọkụ ma nwee ike ịnọgide na-arụ ọrụ kwụsiri ike na okpomọkụ dị elu. N'ime ụfọdụ ngwa pụrụ iche, dị ka ngwaahịa ciment na gburugburu ebe okpomọkụ dị elu, HPMC nwere ike inye nkwụsi ike nke okpomọkụ ka mma, na-ahụ na ngwaahịa ndị ahụ ka nwere ike ịnọgide na-arụ ọrụ nke ọma na ịrụ ọrụ nke ọma n'okpuru ọnọdụ okpomọkụ dị elu.
10. Mee ka mmiri dịkwuo elu na ịdị n'otu
HPMC nwere ike ime ka ihe ndị dị na ciment na ngwaahịa simenti na-ekesa nke ọma ma belata ihe dị iche iche na-arụ ọrụ nke na-adịghị mma. Ọ na-eme ka mmiri dị nro nke slurry dịkwuo mma ma na-ezere ọdịdị nke clumps ma ọ bụ nhazi ihe, si otú ahụ na-eme ka ịdị n'otu na ịdị n'otu n'ime ngwakọta ihe.
