Sulphoaluminate simenti

Sulphoaluminate simende (SAC) imhando yesamende iri kuwana mukurumbira nekuda kwezvimiro zvayo zvakasiyana uye zvakanakira kupfuura mamwe marudzi esimende. SAC is hydraulic simenti inogadzirwa nekubatanidza sulphoaluminate clinker, gypsum, uye shoma shoma ye calcium sulfate. Muchikamu chino, tichaongorora kwakabva, hunhu, zvakanakira, uye mashandisiro e sulphoaluminate simende.

Origins Sulphoaluminate simende yakatanga kugadzirwa kuChina kuma1970s. Yakatanga kushandiswa kune zvakakosha zvikumbiro, senge nekukurumidza-kuisa kongiri uye kugadzirisa dhaka. Mumakore achangopfuura, SAC yakawana mukurumbira seimwe nzira yakagadzikana kune yechinyakare Portland simende.

Hunhu Sulphoaluminate simende ine akati wandei akasiyana maitiro anoita kuti ive yakasiyana nemamwe marudzi esimende. Aya maitiro anosanganisira:

1. Kurumidza kuseta: SAC inogadzika nekukurumidza, ine nguva yekumisikidza yakatenderedza 15-20 maminetsi. Izvi zvinoita kuti ive yakanakira zvikumbiro panodiwa kuseta nekukurumidza, senge mukutonhora kwemamiriro ekunze kana kana kugadzirisa nekukurumidza kuchidikanwa.
2. Kusimba kwekutanga kwekutanga: SAC ine yakakwira simba rekutanga, ine simba rekumanikidza rakatenderedza 30-40 MPa mushure mezuva rimwe rekurapa. Izvi zvinoita kuti ive yakanakira zvikumbiro panodiwa simba rekutanga, senge precast kongiri kana kugadzirisa.
3. Yakaderera kabhoni tsoka: SAC ine yakaderera kabhoni tsoka pane yechinyakare Portland simende, sezvo ichida yakaderera tembiricha panguva yekugadzira uye ine shoma clinker.
4. High sulfate resistance: SAC ine high resistance kurwisa sulfate, iyo inoita kuti ive yakakodzera kushandiswa munzvimbo dzine high sulfate concentrations, dzakadai senzvimbo dzemahombekombe.

Advantages Sulphoaluminate simende inopa zvakati wandei zvakanakira pane mamwe marudzi esimende, anosanganisira:

1. Yakaderedzwa kabhoni tsoka: SAC ine yakaderera kabhoni tsoka pane yechinyakare Portland simende, izvo zvinoita kuti ive sarudzo yakasimba yekuvaka.
2. Kurumidza kugadzirisa: SAC inogadzirisa nekukurumidza, iyo inogona kuchengetedza nguva uye kuderedza mari yekuvaka.
3. Simba rekutanga rekutanga: SAC ine simba rekutanga rekutanga, iro rinogona kuderedza nguva inodiwa pakurapa uye kuwedzera chibereko.
4. High sulfate resistance: SAC ine yakanyanya kupikisa kurwisa sulfate, iyo inogona kuwedzera kusimba kwezvivakwa zvekongiri munzvimbo dzakaoma.

Inoshandisa Sulphoaluminate simenti inoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira:

1. Rapid-setting kongiri: SAC inowanzo shandiswa mumashandisirwo panodiwa kuseta nekukurumidza, senge mukutonhora kwemamiriro ekunze kana kukurumidza kugadzirisa.
2. Precast kongiri: SAC inowanzoshandiswa mukugadzira precast kongiri zvigadzirwa, senge kongiri pombi, slabs, uye mapaneru.
3. Kugadzirisa dhaka: SAC inowanzoshandiswa sedhaka rekugadzirisa zvivakwa zvekongiri, sezvo inogadzika nekukurumidza uye ine simba rekutanga rekutanga.
4. Self-leveling kongiri: SAC inogona kushandiswa kugadzira self-leveling kongiri, iyo yakanakira maapplication panodiwa yakatsetseka, nhanho nzvimbo.

Mhedziso Sulphoaluminate simende imhando yakasarudzika yesimende inopa akawanda mabhenefiti pamusoro pechinyakare Portland simende. Iyo ine yakaderera kabhoni tsoka, inogadzika nekukurumidza, ine yakakwira simba rekutanga, uye inopikisa zvakanyanya kurwisa sulfate. SAC inoshandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira kukurumidza-kugadzika kongiri, precast kongiri, kugadzirisa dhaka, uye self-leveling kongiri. Sezvo kusimba kunova chinhu chinonyanya kukosha mukuvaka, kushandiswa kweSAC kunogona kuwedzera mukurumbira.
