Kusarudzwa kwezvinhu zvakasvibirira uye basa
(1) Vitrified microbead lightweight aggregate
Iyo inonyanya kukosha mudhaka ndeye vitrified microbeads, ayo anowanzo shandiswa zvinopisa zvekudzivirira zvivakwa mukuvaka kwechizvino chivakwa uye zvine yakanaka yekupisa yekupisa zvivakwa. Iyo inonyanya kugadzirwa neye acidic girazi zvinhu kuburikidza nepamusoro-tech kugadzirisa. Kubva pamusoro pedhaka, kugovaniswa kwechikamu chechinhu chacho hachina kurongeka, segomba rine maburi akawanda. Zvisinei, panguva yekuvaka, tinogona kuona kuti chimiro chechinhu ichi chakanyatsonaka, uye chine chisimbiso chakanaka kumadziro. Izvo zvinhu zvakareruka, zvine kunaka kwekupisa kupisa, uye zvine hunhu hwekupisa tembiricha kuramba uye kupfeka kuramba. Chinhu chakakosha pakuvaka zvivakwa zvemazuva ano. Kazhinji kutaura, iyo yekupisa conductivity ye vitrified microbeads chinhu chakatanhamara, kunyanya kupisa kwepamusoro kwepamusoro ndiko kwakasimba, uye kupisa kwekudzivirira zvakare kwakanyanya kwazvo. Naizvozvo, muchirongwa chekushandisa che vitrified microbeads, vashandi vekuvaka vanofanirwa kudzora chinhambwe nenzvimbo pakati pechikamu chimwe nechimwe, kuitira kuti vaone kupisa kwekupisa uye basa rekuchengetedza kupisa kweiyo thermal insulation material.
(2) Kemikari gypsum
Kemikari gypsum chimwe chikamu chakakosha chedhaka. Inogona zvakare kunzi indasitiri yekudzoreredza gypsum. Iyo inonyanya kuumbwa necalcium sulfate tsvina yakasara, saka kugadzirwa kwayo kuri nyore kwazvo, uye inogona kuona kushandiswa kunoshanda kwezviwanikwa uye kuchengetedza simba. Nekuvandudzwa kwehupfumi, mafekitori mazhinji anorasa mamwe marara emaindasitiri uye zvinosvibisa zuva rega rega, senge desulfurized gypsum senge phosphogypsum. Kana marara aya angopinda mumhepo, anozokonzera kusvibiswa kwemhepo uye kukanganisa hutano hwevanhu. Naizvozvo, kemikari gypsum inogona kunzi isimba rinodzokororwa, kushandura marara kuita hupfumi uye kuona kushandiswa kwemarara. Madhipatimendi akakodzera enyika yedu akaita zvimwe zvakanaka mukuchengetedza kwezvakatipoteredza mukutsvaga kwemakemikari gypsum. Zvinoenderana nehuwandu hwekusvibiswa kwehuwandu, phosphogypsum chinhu chinosvibisa zvakanyanya. Kana fekitori ikasaburitsa phosphogypsum kamwe chete, zvinokonzeresa kusvibiswa kwakakomba kunharaunda yakapoteredza. Nekudaro, chinhu ichi chinogona kuve sosi huru yemakemikari gypsum. Element. Kuburikidza nekuongorora uye kupera mvura kwephosphogypsum, vaongorori vakapedza maitiro ekushandura marara kuita pfuma uye vakagadzira makemikari gypsum. Desulfurization gypsum inogona zvakare kunzi flue gasi desulfurization gypsum, inova chigadzirwa cheindasitiri chakaumbwa kuburikidza nedesulfurization uye kucheneswa kurapwa, uye kuumbwa kwayo kwakangofanana neyakasikwa gypsum. Iyo yemahara yemvura yemukati ye desulfurized gypsum inowanzo kwira, iyo yakakwira zvakanyanya kupfuura iyo yeyakasikwa gypsum, uye kubatana kwayo kwakasimba. Matambudziko mazhinji zvakare anowanzo kuitika panguva yese yekugadzira maitiro. Nokudaro, nzira yekugadzira yekuvaka gypsum haigoni kufanana neyechisikigo gypsum. Izvo zvinodikanwa kutora yakakosha kuomesa nzira yekudzikisa hunyoro hwayo. Inoumbwa nekuiongorora uye calcining pane imwe tembiricha. Nenzira iyi chete inogona kusangana neiyo yenyika certification zviyero uye kusangana nezvinodiwa zvekupisa kwekuvaka kwekudzivirira.
(3) Zvinowedzera
Kugadzirira kwemakemikari gypsum insulation mortar kunofanira kushandisa kuvaka kemikari gypsum sechinhu chikuru. Vitrified microbeads inowanzogadzirwa neakareruka aggregate. Vatsvakurudzi vakashandura zvivakwa zvayo kuburikidza nemisanganiswa kuti ienderane nezvinodiwa zvezvirongwa zvekuvaka. Paunenge uchigadzira dhaka rekupisa rinopisa, vashandi vekuvaka vanofanirwa kutarisisa kune hunhu hwekuvaka makemikari gypsum, senge viscosity uye yakakura vhoriyamu yemvura, uye sarudza admixtures nesainzi uye zvine musoro.
1. Composite retarder. Maererano nezvinodiwa zvekuvaka zvezvigadzirwa zvegypsum, nguva yekushanda chiratidzo chakakosha chekushanda kwayo, uye chiyero chikuru chekuwedzera nguva yekushanda ndechekuwedzera retarder. Inowanzo shandiswa gypsum retarders inosanganisira alkaline phosphate, citrate, tartrate, etc. Kunyange zvazvo idzi retarders dzine maitiro akanaka ekugadzirisa, dzichakanganisawo simba rekupedzisira rezvigadzirwa zvegypsum. Iyo retarder inoshandiswa mumakemikari gypsum thermal insulation mortar is a composite retarder, iyo inogona kunyatso kudzikisa kunyungudika kwehemihydrate gypsum, inonoke kukurumidza kwekristalllization germ kuumbwa, uye inonoke muitiro wekristalllization. The retading effect iri pachena pasina kurasikirwa kwesimba.
2. Mvura yekuchengetedza mvura. Kuti uvandudze kushanda kwedhaka, kuvandudza kuchengetedza kwemvura, fluidity uye sag resistance, zvinowanzodiwa kuwedzera cellulose ether. Kushandiswa kwemethyl hydroxyethyl cellulose ether kunogona kuita zvirinani basa rekuchengetedza mvura uye kukora, kunyanya mukuvaka kwezhizha.
3. Redispersible latex poda. Kuti uvandudze kuwirirana, kushanduka uye kunamatira kwevhu kune substrate, redispersible latex powder inofanira kushandiswa semusanganiswa. Redispersible latex powder is powdery thermoplastic resin inowanikwa nekupfapfaidza kuomesa uye kunotevera kugadziridzwa kweyakakwira molecular polymer emulsion. Iyo polymer mumusanganiswa wedhaka chikamu chinoenderera, chinogona kumisa kana kunonoka chizvarwa uye kukura kwekutsemuka. Kazhinji, simba rekubatanidza redhaka rinowanikwa nemusimboti we mechanical occlusion, kureva kuti, zvishoma nezvishoma inosimbiswa mumapupa ezvinyorwa zvepasi; kusungirirwa kwemapolymers kunonyanya kutsamira pakushambadza uye kupararira kwe macromolecules pamusoro pekubatana, uye iyo methyl Iyo hydroxyethyl cellulose ether inoshanda pamwe chete kuti ipinde pamusoro peiyo base layer, ichiita pamusoro peiyo base zvinhu uye pamusoro pedhaka. padyo mukuita, nekudaro kuvandudza adsorption pakati pavo uye zvakanyanya kuvandudza mashandiro ekubatanidza.
4. Lignin fibers. Lignocellulosic fibers zvinhu zvakasikwa zvinotora mvura asi zvisinganyungudika mairi. Basa rayo riri mukushanduka kwayo uye matatu-dimensional network yakaumbwa mushure mekusanganiswa nezvimwe zvinhu, izvo zvinogona kunyatso netesa kuomeswa kwedhaka panguva yekuomeswa kwedhaka, nekudaro ichivandudza kutsemuka kwedhaka. Pamusoro pezvo, iyo yetatu-dimensional nzvimbo chimiro inogona kukiya mvura 2-6 kakapetwa huremu hwayo pakati, iyo ine imwe nzira yekuchengetedza mvura; panguva imwecheteyo, ine thixotropy yakanaka, uye chimiro chichashanduka kana simba rekunze rinoshandiswa (zvakadai sekukwenya uye kubvongodza). Uye yakarongedzwa pamwe negwara rekufamba, mvura inoburitswa, viscosity inoderera, kushanda kunovandudzwa, uye kuita kwekuvaka kunogona kuvandudzwa. Miedzo yakaratidza kuti mapfupi uye epakati marefu e lignin fiber akakodzera.
5. Filler. Kushandiswa kweheavy calcium carbonate (heavy calcium) inogona kushandura kushanda kwedhaka uye kuderedza mutengo.
Kugadzirisa uye kuita
Material musanganiswa ratio:
Chiyero cherabha ndechinotevera, kuvaka kemikari gypsum: 80% ~ 86%; composite retarder: 0.2% ~ 5%; methyl hydroxyethyl cellulose ether: 0.2% ~ 0.5%; redispersible latex poda: 2%～6%; lignin fiber: 0.3% ~0.5%; heavy calcium: 11% ~13.6%. Iyo dhaka musanganiswa reshiyo irabha: vitrified bead = 2: 1 ~ 1.1.
