Makemikari ane ngozi anoreva makemikari ane muchetura uye mamwe makemikari ane muchetura, anoparadza, anoputika, anopisa, anotsigira kupisa uye anokuvadza kumuviri wemunhu, zvivakwa uye zvakatipoteredza.
Yepamusoro-inoshanda-inoderedza mvura yekongiri inonyanyo sanganisira naphthalene mutsara, melamine yakatevedzana uye inoderedza mvura inosanganiswa kubva kwavari, iyo naphthalene yakatevedzana ndiyo huru, inoverengera 67%. Naphthalene series uye melamine series haisi makemikari ane ngozi. Naizvozvo, kongiri superplasticizer haisi yechikamu chemakemikari ane njodzi.
Iyo yakasanganiswa inogona kuderedza zvakanyanya kusanganisa mvura vhoriyamu pasi pemamiriro ekuti kudonha kwekongiri kwakafanana kunonzi yakakwira-inoshanda-inoderedza mvura mumiririri.
Mutengo wekudzikisa mvura weiyo yepamusoro-yepamusoro-inoshanda yekudzikisa mvura inogona kusvika kupfuura 20%. Inonyanya kuumbwa nenaphthalene series, melamine series uye mvura-inoderedza vamiririri inosanganiswa kubva kwavari, iyo naphthalene series ndiyo inonyanya, inoverengera 67%. Kunyanya muChina, mazhinji e superplasticizers ari naphthalene akateedzana superplasticizers ane naphthalene seyakanyanya mbishi zvinhu. Naphthalene series superplasticizer inogona kukamurwa kuita yakakwira concentration products (Na2SO4 content<3%), medium concentration products (Na2SO4 content 3%~10%) uye low concentration products (Na2SO4 content>10%) maererano neNa2SO4 muzvigadzirwa zvayo. . Mazhinji naphthalene akateedzana superplasticizer synthesis zvidyarwa zvine kugona kudzora zvirimo zveNa2SO4 pazasi 3%, uye mamwe mabhizinesi epamberi anogona kutozvidzora pazasi 0.4%.
Chikamu chekushandisa:
Inoshanda kune precast uye yakakandwa-mu-nzvimbo yakasimbiswa kongiri mune akasiyana maindasitiri nezvivakwa zvevagari, kuchengetedza mvura, zvekufambisa, zviteshi, maseru uye mamwe mapurojekiti.
Inoshandiswa kune yakakwirira-simba, ultra-yakakwirira-yakasimba uye yepakati-yakasimba kongiri, pamwe nekongiri inoda simba rekutanga, kuenzanisa kwechando kupikisa uye yakakwirira fluidity.
Prefabricated kongiri zvikamu zvakakodzera kupfungaira kurapa maitiro.
Yakakodzera kugadzira mvura-yekudzikisa uye kusimbisa zvikamu (kureva masterbatch) yeakasiyana-siyana anosanganiswa admixtures.
Haasi we. Makemikari ane ngozi zvinhu zvinoputika. Nekudaro, general kongiri superplasticizer haina zvinhu zvinoputika uye zvinoputika, saka kongiri superplasticizer haisi yemakemikari ane njodzi.
