Kuongororwa kwezvikonzero zvekutsemuka kweplaster yegypsum layer
1. Kuongororwa kwezvikonzero zvekupurasita gypsum zvinhu zvakagadziriswa
a) Purasi yekuvaka isina kukodzera
Gypsum yekuvaka ine huwandu hwakawanda hwe dihydrate gypsum, izvo zvinoita kuti gypsum yekuisa plaster ikurumidze kusungirirana. Kuti gypsum yekuisa plaster ive nenguva yakakodzera yekuvhura, retarder yakawanda inofanira kuwedzerwa kuti mamiriro acho awedzere kuipa; gypsum inonyunguduka isina mvura mukuvaka gypsum AIII Hunhu hwakawanda, kuwedzera kweAIII kwakasimba kupfuura gypsum yeβ-hemihydrate muchikamu chekupedzisira, uye kuchinja kwehuwandu hwe gypsum yekuisa plaster hakuna kuenzana panguva yekupisa, zvichikonzera kutsemuka kukuru; huwandu hwe β-hemihydrate gypsum inorapika mukuvaka gypsum hwakaderera, uye kunyange huwandu hwese hwe calcium sulfate hwakaderera; Gypsum yekuvaka inotorwa kubva ku gypsum yemakemikari, hutete hudiki, uye kune hupfu hwakawanda huri pamusoro pe 400 mesh; saizi ye particle ye gypsum yekuvaka ndeye single uye hapana gradation.
b) Zvimwe zvinhu zvisina kunaka
Haisi mukati me pH inoshanda zvakanyanya ye retarder; kushanda kwegel kwe retarder kwakaderera, huwandu hwekushandiswa hwakakura, simba re plastering gypsum rakaderera zvikuru, nguva iri pakati penguva yekutanga yekugadzika nenguva yekupedzisira yekugadzika yakareba; mwero wekuchengetedza mvura we cellulose ether wakaderera, kurasikirwa nemvura kunokurumidza; cellulose ether inonyunguduka zvishoma nezvishoma, haikodzeri kugadzirwa kwe mechanical spraying.
Mhinduro:
a) Sarudza gypsum yekuvaka yakakodzera uye yakagadzikana, nguva yekutanga yekugadzika inopfuura 3min, uye simba rekuchinjika rinodarika 3MPa.
b) Sarudzaether ye celluloseine saizi diki uye kugona kwayo kuchengetedza mvura zvakanaka.
c) Sarudza retarder isinganyanyi kukanganisa marongero egypsum yekupurasita.
2. Kuongorora zvikonzero zvevashandi vekuvaka
a) Mukondirakita wepurojekiti anotora vashandi vasina ruzivo rwekuvaka uye haadzidzise zvekuvaka nenzira yakarongeka. Vashandi vekuvaka havasati vanyatsonzwisisa hunhu hwekutanga uye zvakakosha pakuvaka gypsum, uye havagone kushanda zvichienderana nemitemo yekuvaka.
b) Kutarisirwa kwehunyanzvi uye manejimendi emhando yepamusoro eyuniti inoita kondirakiti yeinjiniya haana kusimba, hapana vashandi vemanejimendi panzvimbo yekuvaka, uye mashandiro asingatevedzeri evashandi haagone kugadziriswa nenguva;
c) Mabasa mazhinji ekugadzira plaster ne gypsum aripo ari ekuchenesa, achitarisa huwandu uye achiregeredza mhando.
Mhinduro:
a) Vagadziri vemapurojekiti vanopurasita vanosimbisa kudzidziswa kwebasa uye vanozivisa hunyanzvi hwekuvaka vasati vatanga kuvaka.
b) Simbisa manejimendi yenzvimbo yekuvaka.
3. Kuongororwa kwezvikonzero zveplaster yekupurasita
a) Simba rekupedzisira rekuisa gypsum rakaderera uye harigone kuramba kuderera kwesimba kunokonzerwa nekurasikirwa nemvura; simba shoma rekuisa gypsum rinokonzerwa nezvinhu zvisina kufanira kana fomura isina musoro.
b) Kusasimba kwegypsum yekupurasita hakukwaniswi, uye gypsum yekupurasita inoungana pasi, uye ukobvu hwayo hwakakura, zvichikonzera kuputika kwakachinjika.
c) Nguva yekusanganisa gypsum mortar ipfupi, zvichikonzera kusawirirana kwe mertar, simba shoma, kuderera uye kusawirirana kwe gypsum layer yekuplaster
d) Purasitiki yegypsum mortar yakamboiswa pakutanga inogona kushandiswa zvakare mushure mekuwedzera mvura.
Mhinduro:
a) Shandisa gypsum yakagadzirwa nehunyanzvi, iyo inosangana nezvinodiwa zveGB/T28627-2012.
b) Shandisa michina yekusanganisa zvinhu kuti uve nechokwadi chekuti gypsum yekupurasita nemvura zvasanganiswa zvakaenzana.
c) Hazvibvumirwi kuwedzera mvura muhari yakamboiswa pakutanga, wozoishandisa zvakare
4. Kuongororwa kwezvikonzero zvezvinhu zvepakutanga
a) Parizvino, zvinhu zvitsva zvemadziro zvinoshandiswa pakuvaka zvivakwa zvakagadzirwa kare, uye kuoma kwazvo kwekuomesa kwakakura. Kana makore emabhuroko asina kukwana, kana hunyoro hwemabhuroko hwakanyanya, nezvimwewo, mushure menguva yekuoma, mitswe ichaonekwa pamadziro nekuda kwekurasikirwa nemvura nekuoma, uye plastering layer ichatsemukawo.
b) Panosangana nhengo yekongiri yechimiro chefuremu nezvinhu zvemadziro ndipo panosangana zvinhu zviviri zvakasiyana, uye ma coefficients azvo ekuwedzera akasiyana. Kana tembiricha ikachinja, kuchinja kwezvinhu zviviri hakuwirirani, uye mitswe yakasiyana inoonekwa. Makoramu emadziro akafanana Mitswe yakatwasuka pakati pematanda nemitswe yakatwasuka pasi pedanda.
c) Shandisa fomu realuminium kudira kongiri panzvimbo yacho. Pamusoro pekongiri pari pakanyatsotsvedzerera uye pakabatana zvisina kunaka nepurasita yekupurasita. Plasita yekupurasita inobviswa nyore nyore kubva papurasita yekutangira, zvichiita kuti pave nemaburi.
d) Zvinhu zvepasi negypsum yekupurasita zvine musiyano mukuru musimba, uye kana zvakabatana nekuoma kwemvura uye kuchinja kwetembiricha, kuwedzera nekudzika kwemvura hazvienderane, kunyanya kana zvinhu zvepasi pemvura zvine simba shoma uye simba shoma, gypsum yekupurasita inowanzoburitsa chando. Kutsemuka kunotambanudzwa, kunyangwe nzvimbo yakakura yegomba. e) Chikamu chepasi chine mwero wepamusoro wekunyudzwa kwemvura uye kumhanya kwekunyudzwa kwemvura nekukurumidza.
Mhinduro:
a) Hwaro hwekongiri huchangobva kupurastwa hunofanira kuoma kwemazuva gumi muzhizha uye kwemazuva anopfuura makumi maviri muchando kana paine mhepo inofefetera zvakanaka. Pamusoro payo pakanyatsotsvedzerera uye hwaro hunonwisa mvura nekukurumidza. Interface agent inofanira kuiswa;
b) Zvinhu zvinosimbisa madziro zvakaita sejira regrid zvinoshandiswa panosangana madziro nezvinhu zvakasiyana
c) Zvinhu zvemadziro zvakareruka zvinofanira kuchengetedzwa zvizere.
5. Kuongorora zvikonzero zvemaitiro ekuvaka
a) Chikamu chepasi chakaoma zvakanyanya pasina kunyorovesa zvakanaka kana kushandisa chinhu chinopindirana nacho. Gypsum yekupurasita inobatana nechikamu chepasi, hunyoro huri mu gypsum yekupurasita hunokurumidza kunyudzwa, mvura inorasika, uye huwandu hwechikamu che gypsum chekupurasita hunoderera, zvichikonzera kutsemuka, zvichikanganisa kuwedzera kwesimba uye kuderedza simba rekubatanidza.
b) Hunhu hwekuvaka hwaro hwakaipa, uye gypsum layer yemuno yakakora zvakanyanya. Kana plaster yekupurasita ikashandiswa panguva imwe chete, dhaka rinodonha roita mitswe yakatwasuka.
c) Kupwanya kwemagetsi emvura hakuna kubatwa nemazvo. Nzvimbo dzemagetsi emvura hadzizadzwe negypsum inopinza kana kongiri yematombo akanaka ine expansion agent, zvichikonzera kupwanyika, izvo zvinozoita kuti gypsum layer ipurirwe.
d) Hapana mushonga wakakosha wembabvu dzekubaya, uye jira regypsum rekupurasita rakavakwa munzvimbo yakakura rinotsemuka pambabvu dzekubaya.
Mhinduro:
a) Shandisa musanganiswa wemhando yepamusoro kurapa hwaro hwepasi pasina simba rakawanda uye mvura inonyudzwa nekukurumidza.
b) Ukobvu hweplastering gypsum layer hwakakura, hunodarika 50mm, uye hunofanira kukweshwa zvishoma nezvishoma.
c) Itai basa rekuvaka uye simbisa manejimendi emhando yepamusoro panzvimbo yekuvaka.
6. Kuongorora chikonzero chenzvimbo yekuvaka
a) Mamiriro ekunze akaoma uye anopisa.
b) Mhepo inovhuvhuta zvakanyanya
c) Pakupera kwechirimo nezhizha, tembiricha inenge yakakwira uye hunyoro hunenge hwakaderera.
Mhinduro:
a) Kuvaka hakubvumirwi kana paine mhepo ine simba yedanho rechishanu kana kupfuura, uye kuvaka hakubvumirwi kana tembiricha yemhepo yakakwira kupfuura 40 ℃.
b) Pakupera kwechirimo nezhizha, gadzirisa fomura yekugadzira gypsum.
