Plastering plaster ndiyo ichave iyo huru yekupurasita madziro mukati mune ramangwana
Iyo plastering gypsum inoshandiswa kumadziro emukati ine hunhu hwehuremu huremu, kunyudza hunyoro, kuvharidzira ruzha, uye kugadzikana kwekugara kwakasimba.Gypsum plastering zvinhu zvichave zvakakura zvemukati madziro plastering mune ramangwana.
Iyo hemihydrate gypsum inoshandiswa mukati memadziro plastering nhasi inowanzo β-hemihydrate gypsum, uye hemihydrate desulfurized gypsum, kana natural gypsum, kana phosphogypsum inosangana nekuchengetedzwa kwezvakatipoteredza inowanzoshandiswa.Simba remuviri wegypsum rinosiyana kubva 2.5 MPa kusvika 10 MPa.Hunhu hwehemihydrate gypsum inogadzirwa nevagadziri vegypsum hwakasiyana zvakanyanya nekuda kwekusiyana kwezvakagadzirwa zvinhu zvakabva uye maitiro.
Formula Dhizaini yePlastering Gypsum yeUinjiniya
Iyo plastering gypsum inoshandiswa muinjiniya inowanzorema uye ine jecha plastering gypsum.Nekuda kwenzvimbo yakakura yekuvaka, ukobvu hwekuyera hunodarika 1 cm.Vashandi vanoda kukurumidza kuenzana, saka gypsum inodiwa kuti ive yakanaka thixotropy.Kukwesha kwakanaka, kunzwa ruoko rwakareruka, nyore kuratidzwa kuchiedza uye zvichingodaro.
ongorora:
1. Kuita kwakanaka kwekuenzanisa.Kukwidzwa kwejecha kuri nani, shandisa jecha repakati nejecha rakanaka.
2. Good thixotropy.Zvinotarisirwa kuti pfuma yekuzadza yezvinhu zviri nani.Inogona kuwana gobvu, zvakare inogona kuwana yakatetepa.
3. Hapana kupera simba.Shandisa amino acid retarder, yakadai seItaly Plast Retard PE.
Yakakurudzirwa fomula yeinjiniya plastering gypsum:
β-hemihydrate desulfurized gypsum: 250 kg (simba regypsum rinenge 3 MPa)
150-200 mesh heavy calcium: 100 kg (heavy calcium haisi nyore kuva yakanyanya kunaka)
1.18-0.6mm jecha: 400 kg (14 mesh-30 mesh)
0.6-0.075mm jecha: 250 kg (30 mesh-200 mesh)
HPMC-40,000: 1.5 kg (Inokurudzirwa kugeza HPMC katatu, yakachena chigadzirwa, zvishoma gypsum blooming, yakaderera viscosity, zvakanaka ruoko kunzwa, uye duku mhepo-entraining vhoriyamu).
Rheological agent YQ-191/192: 0.5 kg (anti-sag, kuwedzera kuzadza, kunzwa ruoko rwakareruka, kupera kwakanaka).
Plast Retard PE: 0.1 kg (dosage haina kugadziriswa, inogadziriswa maererano necoagulation nguva, mapuroteni, hapana kurasikirwa kwesimba).
Raw material muenzaniso:
1.18-0.6 mm jecha
0.6-0.075mm jecha
β hemihydrate desulfurized gypsum (inenge 200 mesh)
Hunhu hwefomula iyi ndeiyi: kuvaka kwakanaka, kusimba kwekukurumidza.Chiri nyore kusvika padanho, mutengo wakaderera, kugadzikana kwakanaka, kwete nyore kupaza.Inokodzera engineering.
Kutaura kubva pane zvakaitika
1. Iyo gypsum yakadzoka kubva kune imwe neimwe batch inofanira kuongororwa nemaitiro ekugadzira kuti ave nechokwadi chokuti nguva yekuisa haina kuchinja kana kuti iri mukati mekugadzirisa.Zvikasadaro, nguva yekumisikidza yakarebesa uye iri nyore kutsemuka.Kana nguva yacho ipfupi, nguva yekuvaka haina kukwana.Kazhinji, nguva yekutanga yekugadzirisa dhizaini ndeye 60 maminitsi, uye nguva yekupedzisira yegypsum inenge iri pedyo nenguva yekutanga yekugadzirisa.
2. Madhaka ejecha haafaniri kunge akakura, uye madhaka anofanira kudzorwa pa3%.Madhaka akawandisa ari nyore kutsemuka.
3. HPMC, low viscosity, high quality inokurudzirwa.Iyo HPMC yakashambidzwa katatu ine yakaderera munyu, uye gypsum mortar ine chando chishoma.Uku kuoma kwepamusoro uye kusimba kwakanaka
4. Paunenge uchisanganisa poda yakaoma, nguva yekusanganiswa haifaniri kunge yakareba.Mushure mokunge zvinhu zvose zvadyiwa, simbisai kwemaminitsi maviri.Paupfu hwakaoma, iyo yakareba nguva yekusanganiswa, zviri nani.Mushure menguva refu, retarder inorasika zvakare.Inyaya yeruzivo.
5. Sampling yekuongorora zvigadzirwa.Inokurudzirwa kuenzanisa uye kuongorora zvigadzirwa zvakapedzwa kubva pakutanga, pakati uye kupera kwehari imwe neimwe.Nenzira iyi, iwe uchaona kuti nguva yekugadzirisa yakasiyana, uye retarder inofanira kugadziriswa zvakakodzera maererano nezvinodiwa.
