Plastering plaster e tla ba eona ntho e ka sehloohong ea ho rala lebota ka hare nakong e tlang
Gypsum ea plastering e sebelisetsoang marako a ka hare e na le litšobotsi tsa boima bo bobebe, ho monya mongobo, ho kenya molumo, le boiketlo bo matla ba ho phela.Lisebelisoa tsa gypsum plastering e tla ba tsona tse ka sehloohong tsa ho rala lebota ka hare nakong e tlang.
Hemihydrate gypsum e sebelisetsoang ho rala lebota ka hare kajeno hangata ke β-hemihydrate gypsum, le hemihydrate desulfurized gypsum, kapa gypsum ea tlhaho, kapa phosphogypsum e finyellang litlhoko tsa ts'ireletso ea tikoloho e atisa ho sebelisoa.Matla a 'mele oa gypsum a fapana ho tloha ho 2,5 MPa ho ea ho 10 MPa.Boleng ba gypsum ea hemihydrate e hlahisoang ke baetsi ba gypsum bo fapane haholo ka lebaka la phapang ea tšimoloho ea thepa e tala le ts'ebetso.
Moralo oa Foromo ea Plastering Gypsum bakeng sa Boenjiniere
Gypsum e polasterang e sebelisoang boenjiniere hangata ke gypsum e boima ebile e lehlabathe.Ka lebaka la sebaka se seholo sa kaho, botenya ba boemo bo feta 1 cm.Basebetsi ba hloka boemo bo potlakileng, kahoo gypsum e hlokeha ho ba le thixotropy e ntle.Ho phunya hantle, letsoho le bonolo ho utloa, ho bonolo ho pepeseha leseli joalo-joalo.
sekaseka:
1. Ts'ebetso e ntle ea boemo bo holimo.Ho hlophisoa ha lehlabathe ho molemo, sebelisa lehlabathe le mahareng le lehlabathe le letle.
2. thixotropy e ntle.Hoa hlokahala hore thepa ea ho tlatsa thepa e be molemo.E ka fumana e teteaneng, hape e ka fumana e tšesaane.
3. Ha ho tahlehelo ea matla.Sebelisa amino acid retarder, joalo ka Italy Plast Retard PE.
Foromo e khothaletsoang bakeng sa boenjiniere ba plastering gypsum:
β-hemihydrate desulfurized gypsum: 250 kg (matla a gypsum a ka bang 3 MPa)
150-200 mesh k'halsiamo e boima: 100 kg (khalsiamo e boima ha e bonolo ho ba hantle haholo)
1.18-0.6mm lehlabathe: 400 kg (14 mesh-30 mesh)
0.6-0.075mm lehlabathe: 250 kg (30 mesh-200 mesh)
HPMC-40,000: 1.5 lik'hilograma (Ho kgothaletswa ho hlatsoa HPMC ka makhetlo a mararo, sehlahisoa se hloekileng, lipalesa tse fokolang tsa gypsum, viscosity e tlaase, boikutlo bo botle ba matsoho, le molumo o monyenyane oa ho kenya moea).
Rheological agent YQ-191/192: 0,5 kg (anti-sag, eketsa ho tlatsa, boikutlo bo bobebe ba letsoho, qetello e ntle).
Plast Retard PE: 0.1 kg (tekanyetso ha e tsitsitsoe, e lokisoa ho latela nako ea coagulation, protheine, ha ho tahlehelo ea matla).
Mohlala oa thepa e tala:
1.18-0.6 limilimithara lehlabathe
0.6-0.075mm lehlabathe
β hemihydrate desulfurized gypsum (e ka bang 200 mesh)
Litšobotsi tsa foromo ena ke: kaho e ntle, matla a potlakileng.Ho bonolo ho beha boemo, theko e tlase haholo, botsitso bo botle, ha ho bonolo ho petsoha.E loketse boenjiniere.
Ho bua ka phihlelo
1. Gypsum e khutlisitsoeng ho tsoa sehlopheng se seng le se seng e lokela ho hlahlojoa ka foromo ea tlhahiso ho netefatsa hore nako ea ho beha ha e so fetohe kapa e ka har'a mefuta e laoloang.Ho seng joalo, nako ea ho beha e telele haholo 'me ho bonolo ho senya.Haeba nako e le khutšoanyane haholo, nako ea kaho ha ea lekana.Ka kakaretso, nako ea pele ea ho beha moralo ke metsotso ea 60, 'me nako ea ho qetela ea ho beha gypsum e batla e le haufi le nako ea pele ea ho beha.
2. Seretse sa lehlabathe ha sea lokela ho ba seholo haholo, 'me seretse se lokela ho laoloa ho 3%.Seretse se sengata haholo se ka petsoha habonolo.
3. HPMC, viscosity e tlaase, boleng bo phahameng bo khothalletsoa.HPMC e hlatsoitsoeng ka makhetlo a mararo e na le letsoai le tlaase, 'me seretse sa gypsum se na le serame se fokolang.Bongata bona ba bokaholimo le matla li lokile
4. Ha u kopanya phofo e omileng, nako ea ho kopanya ha ea lokela ho ba telele haholo.Ka mor'a hore lisebelisoa tsohle li fepe, hlohlelletsa metsotso e 2.Bakeng sa phofo e omileng, nako e telele ea ho kopanya, e molemo.Kamora nako e telele, retarder le eona e tla lahleha.Ke taba ea phihlelo.
5. Tlhahlobo ea sampole ea lihlahisoa.Ho kgothaletswa ho etsa mohlala le ho hlahloba lihlahisoa tse phethiloeng ho tloha qalong, bohareng le qetellong ea pitsa e 'ngoe le e' ngoe.Ka tsela ena, u tla fumana hore nako ea ho beha e fapane, 'me retarder e lokela ho fetoloa ka nepo ho latela litlhoko.
