Desguzation gypsum by-chigadzirwa gypsum yakawanikwa nekushambadzira uye kuchenesa gasi rinogadzirwa mushure mekusvibirira kweSarufa Kuumbwa kwayo kwemakemikari kwakafanana neiyo yeyakajairika dhizaini gypsum, kunyanya cano4 · 2sh2o. Parizvino, nyika yangu yemagetsi yechizvarwa ichiri kutongwa nemwenje yemarasha, uye iyo So2 yakabuda nemarasha mune maitiro emazinga echizvarwa chechizvarwa chinodarika makumi mashanu muzana emukati memasango egore rangu. Mari yakakura ye sarufa dioxide kusimuka yakonzera kusvibiswa kwakakomba kwezvakatipoteredza. Iko kushandiswa kwehunhu hwegesi kwegasi kwegasi kwehunhu hwekushamwaridzana kuti riugadzire kusuwa kweGypsum iyero yakakosha kugadzirisa hunyanzvi hwekuvandudzwa kweTekineni. Sekureva kwehuwandu husina kukwana, kubviswa kweiyo desguzed gypsum munyika yangu yakadarika mamirioni makumi mapfumbamwe nemashanu.
Gypsum ine mabasa ehuremu hwakareruka, kudzikisira kwemoto, kudzikisira moto, zvinopisa zvekushandisa, zveto zvinogona kushandiswa kugadzirwa kwesimendi, kugadzirwa kwejini kugadzirwa, enginecha yekushongedza uye mamwe minda. Parizvino, nyanzvi zhinji dzakafamba nekutsvagisa plastering plaster. Tsvagurudzo inoratidza kuti Plasterring Plastering zvinhu zvine micro-kuwedzera, kugona kugona uye kupurasitiki, uye kunogona kutsiva zvigadzirwa zvetsika zvekushongedza kwemadziro emadziro. Zvidzidzo naXu jianjun nevamwe vakaratidza kuti vanoparadza gypsum vanogona kushandiswa kugadzira maronda emadziro emadziro. Zvidzidzo zveizvozvo iwe Beihong nevamwe vakapararira gypsum inogadzirwa nedunhu rakapurika rerwendo rwemukati rwevarwi Lightweight Plastering Gypsum ndiyo mhando nyowani yemamiriro ekunze ane hushamwari hweplessing zvinhu. Iyo yakagadzirwa neHemiydrate Gypsum seyakanyanya cementwious zvinhu nekuwedzera marambi ekuremara anounganidza uye admixture. Kuenzaniswa neChinyakare Chemument Closter zvinongedzo, hazvisi nyore kupaza, kunamatira zvakanaka kusunga, zvakanaka shrinkage, green uye dziviriro yezvemamiriro ekunze. Iko kushandiswa kwesimba kweGypsum kuba gadzira Hemhydrate Gypsum kwete kungogadzirisa dambudziko rekuvaka Gypsum zviwanikwa, Naizvozvo, zvichibva pakudzidza kwesimba rekushambadzira, simba rinosindimara uye simba rekumanikidza, kuti dzidzidze hwaro hwekushamisika
1 kuyedza
1.1 zvinhu zvakagadzirwa
Desguzation gypsum powder: Hemhydrate gypsum yakagadzirwa uye yakagadziridzwa neyechinguvanwa microbeads inoonekwa muzvikamu zve4%, 8%, 12%, uye 16%, uye 16%, uye 16%, uye 16%, uye 16% zvichibva pamaruva echiedza yakarongedzerwa desulized gypsum dhaka.
Retarder: Shandisa sodium citrate, makemikari kuongorora kwakacheneswa kunoenderana nehuremu hwechiedza chechiedza, uye iyo ratio iri 0,2%, 0.2%.
Cellulose Ether: Shandisa HydroxyPropyl MetHylcellose (HPMC), Viscosity ndeye 400, HPMC yakavakirwa pachiyero chechiedza chakaputika
1.2 bvunzo nzira
Iko kunwa kwemvura uye kurongedza nguva yeiyo yakajairwa kusungwa kweDhipatimendi Gypsum Plsguzed Gypsum Lb / T17699
Iyo inoshanduka uye inosimbisa masimba emashambadziro ehusimbe Simba rinosindimara uye rinomanikidza yechiedza-huremu hwakapetwa-huremu hwakakurirwa hushamwari
2 mhinduro uye hurukuro
2.1 mhedzisiro yeGypsum Powder yezvinyorwa pazvinhu zvemakwenzi zve leverweight plastinging fashfuration gypsum
Mari yakazara yeGypsum Powder, Limestone Powder uye Lightweight Aggregate ndeye 100%, uye huwandu hwechiedza chakagadziriswa uye kufarirwa kunoramba kuchinjika. Kana huwandu hweGypsum poda iri 60%, 70%, 80%, uye 90%, kushamisika, kushamisika kwemhedzisiro yeGypsum Dorar.
Simba rinosindimara uye simba rekumanikidza rezvemwenje rakaputika kusuwa kweGypsum Drips vese vanowedzera nezera, zvichiratidza kuti iyo hydration degree reGypsum inowedzera nezera. Nekuwedzera kwesimba rekushambadzira, simba rinosindimara uye simba rekumanikidza rekuremedza rakaparara gysum, asi kuwedzera kwacho kwanga kuri madiki, uye simba rekumanikidza mumazuva makumi maviri nemasere raive pachena. Pazera re 1d, iro rakashanduka simba reGypsum Powder rakasanganiswa ne 90% rakawedzera ne10,3% vachienzaniswa neiyo 60% gypsum poda, uye iyo inoenderana simba rekumanikidza simba rakawedzera ne 10.1%. Pazera ramakore makumi maviri nemasere, Simba rinosindimara reGypsum Powder rakasanganiswa ne80% rakawedzera ne8,8% vachienzaniswa neiyo gypsum powder yakasanganiswa ne 60%, uye iyo inoenderana simba rekunyora, Kuti upedze, inogona kugumisa kuti huwandu hweGypsum hupfu hune zvimwe zvinokanganisa simba rinopindirana kupfuura simba rekumanikidza.
2.2 Mhedzisiro yeVarambi Varomeka Aggregate pane iyo Mechancal Properties yeLarsiGight Yakapurika Yakavharirwa Gypsum
Mari yakazara yeGypsum Powder, Limestone Powder uye Lightweight Aggregate ndeye 100%, uye huwandu hweGypsum Gypsum hupfu uye kuyambira zvinoramba zvisina kuchinjika. Kana huwandu hwehutachiona microbeads iri 4%, 8%, 12%, uye 16%, iyo light Plaster yakabuda uye inoshamisa simba rekushambadzira gypsum dhaka.
Pazera rimwe chete, Simba rinosindimara uye simba rekumanikidza rekusanzwisisika rakaputika rakashongedzwa gypsum motsi rakadzikira neyekuwedzera kwezvakareredzwa microbeads. Izvi zvinodaro nekuti mazhinji emakiromita akakwenenzverwa ane hombodo yemukati uye simba ravo rakaderera, iro rinoderedza simba rinosindimara uye rinomanikidza yeiyo lightweight plastouring gysum moter. At 1 zera, Simba rinosindimara regumi nematanhatu regumi nenomwe regumi nenomwe rakaderedzwa neaya 35.3% vachienzaniswa neiyo 4% gypsum poda, uye simba rinoenderana rakaderedzwa ne1.3%. Pazera ramazuva makumi maviri nemasere, Simba rinosindimara regumi nematanhatu regumi nenomwe Kuti upedze, zvinogona kugumisa kuti mhedzisiro yezvinyorwa zvecorsebeads inokandirwa pane yakashanduka simba iri yakakura kupfuura iyo simba rekumanikidza.
2.3 Mhedzisiro yeRubstarder Comment pane yekuisa nguva yechiedza chakapururudza desguzed gypsum
Iyo yakazara Dosage yeGypsum Powder, Limestone Powder uye Lightweight Aggregate ndeye 100%, uye Dosage yeGypred Gypsum, Limestone Powder, Litweight Aggregate uye Cellulose Ether inosara isina kuchinjika. Kana dosage yeSodium Citrate is 0, 0,1%, 0.2%, kuisa nguva, kugadzirisa nguva mhedzisiro yechiedza chakasarudzika gypsum moter.
Iyo yekutanga yekuisa nguva uye yekupedzisira yekuisa nguva yechiedza chakapururudza chakashambadzirwa gypsum Kana iyo sodium citrate zvemukati 0.3%, iyo yekutanga yekuisa nguva inowedzera 28min, uye yekupedzisira nguva yekugara yakavezwa ne39min. Kuwedzeredza kweiyo nguva yekugara kunogona kuve nekuda kwenzvimbo yakakura yekuparadzwa kweiyo gypsum zvimedu zveGypsum, zvichikonzera kutadza kweiyo gypsum slurry kuti iite chimiro chakasimba. Inowedzera nguva yekuisa gypsum.
2.4 Mhedzisiro ye cellulose etter zvemukati pazvinhu zvemakwenzi zvezvinyorwa zvekuremerwa zvakapururudzwa zvakazara gypsum
Iyo yakazara Dosage yeGypsum Powder, Limestone Powder uye Lightweight Aggregate ndeye 100%, uye Dosage yeGypsum Powder, Limestone Powder, Litweight Aggregate uye Returderer inoramba isina kuchinjika. Kana dosay ye hydroxyprusyl methylcellose is 0, 0,1%, 0.2% uye inokatyamadza uye inokatyamadza migariro yakarongedzwa yakajeka gypsum dhaka.
Panguva 1 zera, simba rinosindimara remagetsi rakaputika rakakuvara gypsguzed gypsum lars rekutanga kuwanda uyezve rakadzikira nekuwedzera kwehydroxyproproproplulose; Pana 28 zera, simba rinosindimara remagetsi rakaputika madhiri ane madhiri ehuma Kana zviri mukati mehydroxypropyl methylcellose ndeye 0.2%, isimba rinosindimara rinosvika kuCellulose. Damba maitiro anooneka ari pachena pa 28D. Izvi zvinodaro nekuti cellulose ether ane mhedzisiro yekuchengetwa kwemvura uye kuremerwa, uye iyo mvura yekuda kuwanda kwemari yemvura, nekudaro ichidzora simba re gypsum fungidziro.
3 Mhedziso
(1) Iyo hydration degree rekushambadzira gypsum rinova rakaringana nezera. Nekuwedzera kwekushungurudzika kweGypsum Powder Zvinyorwa, simba rinosindimara uye rinonamira uye rinomanikidza rekuremedza kupurudzira gystopresum rakaratidza maitiro ese kumusoro, asi kuwedzera kwacho kwanga kuri madiki.
