Polyurethane/polyurea spraying machinemugadziri, michina yacho inokodzera kupisa kwemafuta, kusapinda kwemvura, anti-corrosion, kudurura, nezvimwe.
Kupfapfaidza polyurethane kunofanirwa kuitwa munzvimbo dzakawanda.Zvichida vanhu vazhinji vakaona nzira yekuvaka ye polyurethane spraying, asi havazivi zvachose nzvimbo dzekuvaka dze polyurethane spraying, uye havazivi kuti maitiro eunyanzvi akaita sei.Nhasi ndichakuratidzai mese Tsanangura nzira yekuvaka ye polyurethane spraying.

1. Basic interface processing
Rusvingo rwechigadziko runofanira kusangana nezvinodiwa, kupfava kwemadziro kunofanirwa kunge kuri 5-8mm, uye verticality inofanira kunge iri mukati me10mm.
A: Rusvingo runofanira kucheneswa kuti ruve nechokwadi chokuti rusvingo haruna kusununguka kubva kune laitance, mavara emafuta, guruva, nezvimwewo. Kana kutsauka kwechigadziko chepamusoro chakanyanya kukura, dhaka rinofanira kushandiswa pakuenzanisa.
B: Kuremara pamadziro kwakagadziriswa nesamende dhaka.
C: Kana madziro emadziro akakura kupfuura kana akaenzana ne10mm, inofanira kubviswa.
D: Mapaipi akavigwa, mabhokisi ewaya uye zvikamu zvakadzimirirwa pamadziro zvinofanirwa kuiswa pachine nguva, uye pesvedzero yehukobvu hweiyo insulation layer inofanirwa kutariswa.
E: Usati wapfapfaidza polyurethane rigid foam, shandisa firimu repurasitiki, pepanhau remarara, bhodhi repurasitiki kana bhodhi rehuni, plywood kuvhara nekudzivirira mahwindo, magonhi uye zvimwe zvisiri zvekuputira zvinhu.Gonhi redenga uye furemu yehwindo zvinofanirwa kupfapfaidzwa nepolyurethane rigid foam isati yaiswa kudzivirira kusvibiswa.

2. Kurembera horizontal uye elastic control line
Mabhaudhi ekuwedzera anoiswa pasi pemadziro epamusoro nemadziro epasi senzvimbo inorembera yewaya huru inorembera.Iyo theodolite inoshandiswa kuisa waya inorembera kune skyscrapers, uye waya huru inoshandiswa kune akawanda-storey zvivakwa kurembera waya yakatetepa yakaturika waya, uye kuisimbisa newaya tensioner.Isa mitsetse yesimbi yakatwasuka pamakona makuru eyin uye yang emadziro, uye chinhambwe chiri pakati pemitsara yakatwasuka yesimbi uye kumadziro ndiko kukora kwese kweiyo thermal insulation layer.Mushure mekurembera mutsara, tanga watarisa flatness yemadziro ane 2m bar mutongi pane imwe neimwe pasi, uye tarisa verticality yemadziro ne 2m bhodhi rekutsigira.Iyo purojekiti inogona kuitwa chete kana izvo zvinodiwa flatness zvasangana.

3. Kumwaya rigid furo polyurethane
Batidza muchina wekupfapfaidza wepolyurethane kupfapfaidza iyo yakaoma furo polyurethane zvakaenzana pamadziro.
A: Kupfapfaidza kunofanira kutanga kubva kumucheto, mushure mekupupuma furo, pfapfaidza pamucheto unopupuma.
B: Ukobvu hwekutanga hwekupfapfaidza hunofanirwa kudzorwa paanenge 10mm.
C: Ukobvu hwekupfuura kwechipiri hunofanirwa kudzorwa mukati me15mm kusvika ukobvu hunodiwa nedhizaini.
D: Mushure mekunge polyurethane yakaomesesa foam insulation layer yakapfapfaidzwa, ukobvu hweiyo insulation layer inofanirwa kutariswa sezvinodiwa, uye kuongororwa kwemhando kunofanirwa kuitwa zvinoenderana nezvinodiwa zvebheti rekuongorora rekodhi rekodhi.
E: Mushure mekupfapfaidza polyurethane insulation layer kwemaminitsi makumi maviri, shandisa planer, saha yeruoko uye zvimwe zvishandiso kuti utange kuchenesa, cheka shading, chengetedza zvidimbu uye zvikamu zvakabuda zvinodarika ukobvu hwakatarwa ne1cm.

4. Kupenda iyo interface mortar
Iyo polyurethane interface dhaka kurapwa inoitwa maawa mana mushure mekunge polyurethane base layer yapfapfaidzwa, uye iyo interface dhaka inogona kupfekedzwa zvakaenzana pa polyurethane insulation base layer ine roller.Kuti usimbise musanganiswa pakati pe insulation layer uye flat layer, kudzivirira kutsemuka nekudonha, uye zvakare kudzivirira iyo polyurethane insulation layer kuti isaonekwe nechiedza chezuva uye ichikonzera yero uye chalking.Mushure mekumwaya iyo polyurethane interface dhaka kwemaawa 12-24, kuvakwa kweiyo nzira inotevera kunoitwa.Ziva kuti iyo polyurethane interface mortar haigone kupfapfaidzwa pamazuva ekunaya.

5. Kuvakwa kwe-anti-cracking mortar layer uye kupera kwekupedzisira
(1) Pendi kupera
① Isa dhaka risingapindike uye woisa pasi alkali-resistant mesh machira.Iyo alkali-resistant mesh inosvika 3m pakureba, uye saizi inofanochekwa.Iyo anti-kutsemuka dhaka inowanzopedzwa mumapasi maviri, nehupamhi hwese hunosvika 3mm kusvika 5mm.Mushure mekupukuta dhaka risingaputse nenharaunda yakaenzana nejira remambure, dzvanya jira rinodzivirira alkali nesimbi.Iyo inopindirana hupamhi pakati pe alkali-resistant mesh machira haafanire kunge ari pasi pe50mm.Pakarepo dzvanya alkali-resistant mesh jira rine simbi trowel muhurongwa kubva kuruboshwe kuenda kurudyi uye kubva kumusoro kusvika kuzasi, uye yakaoma kupindirana kunorambidzwa zvachose.Iyo yin uye yang makona anofanirwawo kupindirana, uye hupamhi hwepamusoro hunofanirwa kunge huri ≥150mm, uye mativi uye kuchinjika kweyin uye yang makona anofanirwa kuvimbiswa.Iro alkali-resistant mesh jira rinofanirwa kunge ririmo mudhaka rinopesana nekutsemuka, uye paving inofanira kunge yakatsetseka uye isina kuunyana.Iyo mesh inogona kuoneka zvisina kujeka, uye dhaka rakazara.Zvikamu zvisina kuzara zvinofanirwa kuzadzwa nekukurumidza ne-anti-cracking mortar kechipiri kusvika padanho uye compact.
Mushure mekunge anti-crack mortar kuvaka yapera, tarisa kutsetseka, verticality uye squareness yeyin uye yang makona, uye shandisa anti-crack mortar kugadzirisa kana isingaite zvinodiwa.Izvo zvinorambidzwa zvachose kushandisa zvakajairwa simende dhaka waistline, mahwindo emaoko, nezvimwewo pane ino yepamusoro.
②Penya iyo inochinjika inodzivirira mvura putty uye isa pendi yekupedzisa.Mushure mokunge chigadziro chinopesana nekuputika chaoma, sveta iyo inogadziriswa mvura-inodzivirira putty (yakabudirira kakawanda, kukora kwega kwega kunodzorwa kunenge 0.5mm), uye kuvhara kwekupedzisa kunofanira kuva kwakachena uye kwakachena.
(2) Kupera kwezvidhinha
① Isa dhaka risingapindike uye wowaridza kupisa-dip galvanized welded waya mesh.
Mushure mekunge ganda rekudzivirira rakatariswa uye rakagamuchirwa, dhaka rinopesana nekuputika rinoshandiswa, uye ukobvu hunodzorwa pa2mm kusvika 3mm.Cheka inopisa-dip galvanized welded wire mesh zvichienderana nekukura kwechimiro, uye uise muzvikamu.Kureba kwekupisa-kunyura-galvanized welded waya mesh hakufaniri kudarika 3m.Kuti uve nechokwadi chekuvakwa kwemakona, iyo inopisa-dip galvanized welded wire mesh pamakona inofanopetwa kuita kona yekurudyi isati yavakwa.Mukati mekucheka mesh, mesh haifaniri kupetwa mumapuranga akafa, uye mesh pocket haifaniri kuumbwa panguva yekuisa.Mushure mekunge mesh yakavhurwa, inofanirwa kuiswa pasi mukutenderera munzira.Zingi welded waya mesh kuti ive pedyo nechepamusoro pe-anti-crack mortar, uye wobva wabatidza inopisa-dhipi yakakwenenzverwa newaya mesh pahwaro kumadziro nemabhaudhi ekuwedzera naironi.Ratidza kusaenzana neklipu yakaita U-.Hupamhi hwemakumbo pakati pekupisa-dip galvanized welded meshes haifanire kunge iri pasi pe50mm, huwandu hwemachira akaturikidzana hahufanire kunge hwakakura kupfuura 3, uye majoini emakumbo anofanirwa kugadzirwa neU-shaped clips, waya dzesimbi kana mabhaudhi anchor.Simende zvipikiri uye gaskets zvinofanirwa kuiswa kumagumo ekupisa-kunyura kwakabatiswa galvanized welded waya mesh padivi remukati rehwindo, madziro emadziro, settlement joint, nezvimwewo, kuitira kuti inopisa-dip galvanized welded welded mesh igadzirwe. chimiro chikuru.
Mushure mekunge kupisa-kunyura kwakagadzirwa newaya mesh kwaiswa uye kwapfuura kuongororwa, iyo anti-crack mortar ichaiswa kechipiri, uye inopisa-dip yakakwenenzverwa welded waya mesh ichaputirwa mu-anti-crack mortar.Iyo yakatsemuka dhaka repamusoro pedenga rinofanira kusangana nezvinodiwa zvekudzika uye verticality.
②Matairi evhavha.
Mushure mekunge anti-crack mortar kuvaka kwapera, inofanirwa kupfapfaidzwa uye kuporeswa, uye iyo veneer tile paste process inogona kuitwa mushure memazuva manomwe.Ukobvu hwechidhinha chekubatanidza dhaka hunofanira kudzorwa mukati me3mm kusvika 5mm.
