A. Khetho ea thepa e tala le mosebetsi
1. Vitrified microbead lightweight aggregate
Motsoako oa bohlokoahali oa seretse ke li-microbeads tse nang le vitrified, tseo hangata li sebelisoang ka thepa ea ho kenya mocheso ka har'a moaho oa sejoale-joale ebile li na le thepa e ntle ea ho kenya mocheso.Haholo-holo e entsoe ka thepa ea khalase ea asiti ka ts'ebetso ea theknoloji e phahameng.
Ho tloha ka holim'a seretse, kabo ea likaroloana ea thepa e sa tloaeleha ka ho fetisisa, joaloka sekoti se nang le masoba a mangata.Leha ho le joalo, nakong ea ts'ebetso ea kaho, sebopeho sa thepa ena ha e le hantle se boreleli haholo, 'me se na le tiiso e ntle leboteng.Boitsebiso bo bobebe haholo, bo na le mocheso o motle oa mocheso, 'me o na le litšobotsi tsa ho hanyetsa mocheso o phahameng le ho hanyetsa ho apara.
Ka kakaretso, conductivity ea mocheso oa li-microbeads tsa vitrified ke tšobotsi e hlahelletseng, haholo-holo mocheso oa mocheso oa holim'a metsi o matla ka ho fetisisa, 'me ho hanyetsa mocheso ho boetse ho phahame haholo.Ka hona, nakong ea ts'ebeliso ea li-microbeads tse nang le vitrified, basebetsi ba kaho ba lokela ho laola sebaka le sebaka se pakeng tsa karolo e 'ngoe le e' ngoe e le ho hlokomela ts'ebetso ea mocheso oa mocheso le ts'ebetso ea mocheso oa mocheso oa thepa ea mocheso oa mocheso.
B. Plaster ea lik'hemik'hale
Gypsum ea lik'hemik'hale ke karolo e 'ngoe ea bohlokoa ea seretse.E ka boela ea bitsoa gypsum ea ho hlaphoheloa ha indasteri.Haholo-holo e entsoe ka masala a litšila tsa calcium sulfate, kahoo tlhahiso ea eona e bonolo haholo, 'me e ka lemoha tšebeliso e ntle ea lisebelisoa le ho boloka matla.
Ka nts'etsopele ea moruo, lifeme tse ngata li ntša litšila tse ling tsa indasteri le litšila letsatsi le leng le le leng, joalo ka gypsum e senyehileng joalo ka phosphogypsum.Hang ha litšila tsena li kena sepakapakeng, li tla baka tšilafalo ea moea le ho ama bophelo ba batho.Ka hona, gypsum ea lik'hemik'hale e ka boleloa e le mohloli oa matla a tsosolositsoeng, hape e hlokomela ts'ebeliso ea litšila.
Ho latela lipalo-palo tse fapaneng tsa tšilafalo, phosphogypsum ke ntho e batlang e silafatsa haholo.Haeba fektheri e sa ntše phosphogypsum hang, e tla baka tšilafalo e tebileng tikolohong e haufi.Leha ho le joalo, ntho ena e ka fetoha mohloli o ka sehloohong oa lik'hemik'hale tsa gypsum.Element.Ka ho hlahloba le ho felloa ke metsi phosphogypsum, bafuputsi ba ile ba qeta mokhoa oa ho fetola litšila hore e be letlotlo 'me ba theha lik'hemik'hale tsa gypsum.
Desulfurization gypsum e ka boela ea bitsoa flue gas desulfurization gypsum, e leng sehlahisoa sa indasteri se entsoeng ka phekolo ea desulfurization le tlhoekiso, 'me sebopeho sa eona se tšoana hantle le sa gypsum ea tlhaho.Metsi a mahala a gypsum ea desulfurized hangata a phahame, a phahame haholo ho feta a gypsum ea tlhaho, 'me momahano oa eona o batla o le matla.Mathata a mangata a boetse a atisa ho etsahala nakong eohle ea ts'ebetso ea tlhahiso.Ka hona, ts'ebetso ea tlhahiso ea ho haha gypsum e ke ke ea tšoana le ea gypsum ea tlhaho.Hoa hlokahala ho amohela mokhoa o khethehileng oa ho omisa ho fokotsa mongobo oa eona.E thehoa ka ho e hlahloba le ho calcining ka mocheso o itseng.Ke ka tsela ena feela e ka finyellang litekanyetso tsa setifikeiti sa naha le ho finyella litlhoko tsa kaho ea ho kenya mocheso oa mocheso.
C. Motsoako
Ho lokisoa ha seretse sa lik'hemik'hale sa gypsum insulation ho tlameha ho sebelisa k'hemik'hale ea gypsum e le thepa ea mantlha.Li-microbeads tse nang le vitrified hangata li entsoe ka kakaretso e bobebe.Bafuputsi ba fetotse thepa ea eona ka li-adixtures ho fihlela litlhoko tsa merero ea kaho.
Ha ho etsoa seretse se futhumatsang mocheso, basebetsi ba kaho ba lokela ho ela hloko litšobotsi tsa gypsum ea lik'hemik'hale, joalo ka viscosity le bophahamo bo boholo ba metsi, 'me ba khethe li-admixtures ka saense le ka bohlale.
1. Composite retarder
Ho ea ka litlhoko tsa kaho ea lihlahisoa tsa gypsum, nako ea ho sebetsa ke pontšo ea bohlokoa ea ts'ebetso ea eona, 'me tekanyo e ka sehloohong ea ho lelefatsa nako ea ho sebetsa ke ho eketsa retarder.Li-retarders tsa gypsum tse sebelisoang ka tloaelo li kenyelletsa alkaline phosphate, citrate, tartrate, joalo-joalo Le hoja li-retarders tsena li na le phello e ntle ea ho lieha, li tla boela li ama matla a morao-rao a lihlahisoa tsa gypsum.The retarder sebelisoa ka lik'hemik'hale gypsum thermal insulation seretse ke composite retarder, e ka ka katleho fokotsa solubility ea hemihydrate gypsum, liehe lebelo la crystallization kokoana-hloko sebopeho, le liehisa tshebetso crystallization.Phello ea ho lieha e bonahala ntle le tahlehelo ea matla.
2. Thickener ea ho boloka metsi
E le ho ntlafatsa ts'ebetso ea seretse, ho ntlafatsa ho boloka metsi, ho phalla ha metsi le ho hanyetsa, hangata hoa hlokahala ho eketsa cellulose ether.Tšebeliso ea methyl hydroxyethyl cellulose ether e ka bapala karolo e ntle ea ho boloka metsi le ho teteaneng, haholo-holo kahong ea lehlabula.
3. Redispersible latex phofo
E le ho ntlafatsa momahano, ho feto-fetoha ha maemo le ho khomarela seretse ho substrate, redispersible latex powder e lokela ho sebelisoa e le motsoako.Redispersible latex powder ke phofo ea thermoplastic resin e fumanoang ka ho omisa ka spray le ts'ebetso e latelang ea emulsion e phahameng ea molek'hule ea polymer.Polymer ka motsoako oa seretse ke mohato o tsoelang pele, o ka thibelang ka katleho kapa oa lieha ho hlahisa le ho nts'etsopele ea mapetsong.Hangata, matla a tlamahano a seretse a finyelloa ka molao-motheo oa ho koala mochine, ke hore, butle-butle o tiisoa ka likheo tsa thepa ea motheo;tlamahano ea li-polymers e itšetlehile haholo ka ho ata le ho hasana ha li-macromolecules holim'a tlamahano, 'me methyl The hydroxyethyl cellulose ether e sebetsa hammoho ho kenella ka holim'a lera la motheo, ho etsa bokaholimo ba thepa ea motheo le bokaholimo ba seretse. haufi le ts'ebetso, ka hona ho ntlafatsa papatso pakeng tsa bona le ho ntlafatsa haholo ts'ebetso ea bonding.
4. Lignin fiber
Li-lignocellulosic fibers ke lisebelisoa tsa tlhaho tse monyang metsi empa ha li qhibilihe ho tsona.Mosebetsi oa eona o itšetlehile ka ho feto-fetoha ha eona le sebopeho sa marang-rang se nang le mahlakore a mararo se entsoeng ka mor'a ho kopanya le lisebelisoa tse ling, tse ka fokolisang ka katleho ho fokotseha ha seretse nakong ea ho omisa ha seretse, ka tsela eo ho ntlafatsa ho hanyetsa ho phatloha ha seretse.Ho phaella moo, sebopeho sa sebaka sa mahlakore a mararo se ka koala metsi ka makhetlo a 2-6 boima ba oona bohareng, se nang le phello e itseng ea ho boloka metsi;ka nako e ts'oanang, e na le thixotropy e ntle, 'me mohaho o tla fetoha ha matla a ka ntle a sebelisoa (a kang ho senya le ho hlohlelletsa).'Me e hlophisitsoe ka tsela ea ho sisinyeha, metsi a lokolloa, viscosity e fokotseha, ho sebetsa hoa ntlafatsoa,' me mosebetsi oa kaho o ka ntlafatsoa.Liteko li bontšitse hore bolelele bo bokhutšoane le bo bohareng ba likhoele tsa lignin li loketse.
5. Motlatsi
Tšebeliso ea heavy calcium carbonate (heavy calcium) e ka fetola ho sebetsa ha seretse le ho fokotsa litšenyehelo.
6. Karo-karolelano ea ho itokisa
Gypsum ea lik'hemik'hale tsa kaho: 80% ho 86%;
Composite retarder: 0.2% ho 5%;
Methyl hydroxyethyl cellulose ether: 0.2% ho 0.5%;
Redispersible latex phofo: 2% ho 6%;
Lignin fiber: 0.3% ho 0.5%;
Khalsiamo e boima: 11% ho 13.6%;
Karolelano ea motsoako oa seretse ke rabara: lifaha tsa vitrified = 2: 1 ~ 1.1.
7. Mokhoa oa ho haha

2) Ngolisa lebota.
3) Leketlisa mela e otlolohileng, e sekoere, le ea botenya ba plaster.
4) Sebelisa moemeli oa sebopeho.
5) Etsa likuku tse bohlooho le li-tendon tse tloaelehileng.
6) Etsa kopo ea lik'hemik'hale tsa gypsum vitrified bead insulation seretse.
7) Ho amoheloa ha lera le futhumetseng.
8) Kenya seretse sa gypsum anti-cracking, 'me u hatelle ka lesela la letlooeng la khalase le sa keneleng alkali ka nako e le 'ngoe.
9) Ka mor'a ho amoheloa, penta lesela le ka holimo ka plaster.
10) Ho sila le ho kolokisa.
11) Kamohelo.
8. Qetello
Ho akaretsa, seretse se kenyang mocheso ke e 'ngoe ea lisebelisoa tsa bohlokoa tsa ho kenya mocheso boenjiniere ba kaho.E na le lisebelisoa tse ntle tsa mocheso le thepa ea ho kenya mocheso, e ka fokotsang litšenyehelo tsa ho kenya letsoho tsa boenjiniere ba kaho le ho hlokomela poloko ea matla le tšireletso ea tikoloho ho boenjiniere ba kaho.
Ka nts'etsopele e tsoelang pele ea sechaba, haufinyane, bafuputsi naheng ea rona ba tla nts'etsapele lisebelisoa tse betere le tse sireletsang tikoloho.
