JINJI ® HPMC ejiri mee ihe na nhazi onwe
Ngwakọta ndị na-edozi onwe ha bụ ngwakọta kemịkalụ eji eme ka kọmpụta na-enweghị isi ma ọ bụ ala osisi. Ihe mejupụtara ha bụ simenti, aja, ihe ndochi, ma gbanwee ya site n'ọtụtụ ihe mgbakwunye dị ka cellulose ethers, plasticizers, defoamers, stabilizers, and redisspersible powders. Dị ka ihe na-asọ asọ, nke na-eme ka ọ dị elu na nke na-edozi onwe ya, ogige ndị na-edozi onwe ya nwere ike ịmepụta elu dị larịị, dị nro na nke siri ike nke nwere ike mkpakọ dị mma.
Mgbakwunye nke HPMC nwere ike welie ihe ndị a na ngwa nhazi ọkwa onwe onye:
Ntughari
Dị ka ngwa agha na-ebuli onwe ya elu, mmiri mmiri bụ otu n'ime isi ihe na-egosi iji nyochaa arụmọrụ nke onwe. N'okpuru premise nke n'ịhụ na iwu nke ngwa agha mejupụtara, na fluidity nke ngwa agha nwere ike gbanwee site na-agbanwe ọdịnaya nke eriri HPMC. Otú ọ dị, nnukwu ọdịnaya ga-ebelata mmiri mmiri nke ngwa agha, ya mere ekwesịrị ịchịkwa ọnụọgụ cellulose ether n'ime oke ezi uche.
Njide mmiri
Njide mmiri Mortar bụ ihe dị mkpa na-egosi nkwụsi ike nke ihe dị n'ime nke ngwa ciment ọhụrụ. Iji mee ka mmeghachi omume hydration nke ihe gel na-arụ n'ụzọ zuru ezu, ọnụ ọgụgụ kwesịrị ekwesị nke cellulose ether nwere ike idobe mmiri n'ime ngwa agha ogologo oge. N'ozuzu, njide mmiri nke slurry na-abawanye na mmụba nke cellulose ether ọdịnaya. Njide mmiri nke cellulose ether nwere ike igbochi mkpụrụ ahụ ka ọ ghara ịmịkọrọ mmiri dị ukwuu ngwa ngwa ma gbochie ikuku mmiri, si otú ahụ hụ na ebe mmiri na-ekpo ọkụ na-enye mmiri zuru oke maka hydration ciment. Na mgbakwunye, viscosity nke cellulose ether nwekwara mmetụta dị ukwuu na njide mmiri nke ngwa agha. Nke dị elu nke viscosity, ka mma na-ejigide mmiri.
Ịtọ oge
HPMC nwere mmetụta ntọala ngwa ngwa na ngwa agha. Site na mmụba nke ọdịnaya ether cellulose, oge nhazi nke ngwa agha na-agbatịkwu oge. Mmetụta azụ azụ nke cellulose ether na ciment slurry na-adabere karịsịa n'ókè nke nnọchi nke otu alkyl, nke na-enweghị ihe jikọrọ ya na ịdị arọ ya. N'ókè nke ngbanwe nke alkyl dị ala, ka ọdịnaya hydroxyl dị elu, otú ahụ ka ọ na-apụta ìhè karịa mmetụta azụ azụ. Na elu ọdịnaya nke cellulose ether, ka doro anya na retarding mmetụta nke mejupụtara ihe nkiri na mmalite hydration nke ciment. Ya mere, mmetụta na-ebelata ka ọ na-abawanye.
Ngwa agha na-ebuli onwe ya nwere ike ịdabere n'ịdị arọ nke onwe ya iji mepụta ntọala dị larịị, dị nro na nke siri ike na mkpụrụ maka ịtọ ma ọ bụ jikọta ihe ndị ọzọ, ebe na-enye ohere ịrụ ọrụ nke ọma n'elu nnukwu mpaghara.
