cov xim pleev xim rau cov qauv hlau

Hlau yog ib hom khoom siv hauv tsev uas tsis kub hnyiab, nws muaj kev tiv thaiv av qeeg, khoov thiab lwm yam ntxwv. Hauv kev siv tiag tiag, hlau tsis tsuas yog ua rau lub peev xwm thauj khoom ntawm cov tsev ntau ntxiv xwb, tab sis kuj ua tau raws li qhov xav tau ntawm kev ua qauv zoo nkauj ntawm kev tsim vaj tsev. Nws kuj zam qhov tsis zoo uas cov khoom siv hauv tsev xws li pob zeb tsis tuaj yeem khoov thiab ncab. Yog li ntawd, hlau tau raug nyiam los ntawm kev lag luam kev tsim kho, ib txheej, ntau txheej, skyscrapers, Hoobkas, tsev rau khoom, chav tos, chav tawm mus thiab lwm yam hlau yog qhov tshwm sim. Yuav kom kawm tau los ntawm ib leeg, kev sivcov txheej txheem hlauthiabhlau primerxim yog qhov tseem ceeb.

Kev faib tawm ntawm cov txheej txheem hlau

Cov txheej txheem hlau feem ntau muaj ob hom txheej txheem hluav taws kub ntawm cov qauv hlau thiab cov txheej txheem tiv thaiv xeb ntawm cov qauv hlau.
(A) cov qauv hlau pleev xim tiv taus hluav taws

1. Txheej txheem hluav taws kub uas nyias nyias

Cov txheej txheem tiv thaiv hluav taws xob ntawm cov qauv hlau ultra-thin yog hais txog cov txheej tuab uas tsis pub dhau 3 hli (xws li 3 hli), qhov zoo nkauj zoo nkauj, tuaj yeem nthuav dav thaum kub siab, thiab qhov txwv tsis pub hluav taws kub feem ntau tsis pub dhau 2 teev ntawm cov txheej txheem tiv thaiv hluav taws kub ntawm cov qauv hlau. Hom txheej txheem tiv thaiv hluav taws kub no feem ntau yog cov txheej txheem ua los ntawm cov kuab tshuaj, nrog lub zog sib txuas zoo, tiv taus huab cua thiab dej zoo, ua kom tiaj tus zoo, thiab muaj cov yam ntxwv zoo nkauj; Thaum raug hluav taws, nws maj mam nthuav dav thiab ua npuas dej los ua ib txheej rwb thaiv tsev uas tuab thiab tawv tiv taus hluav taws. Cov txheej txheem tiv thaiv hluav taws kub muaj cov yam ntxwv tiv taus hluav taws kub, ncua qhov kub nce ntawm cov hlau thiab tiv thaiv cov khoom hlau zoo. Kev tsim cov txheej txheem tiv thaiv hluav taws kub ultra-thin tuaj yeem txau, txhuam lossis dov, feem ntau siv rau hauv qhov txwv tsis pub hluav taws kub hauv 2 teev ntawm cov qauv hlau. Muaj ntau hom tshiab ntawm cov txheej txheem tiv thaiv hluav taws xob ultra-thin steel uas tiv taus hluav taws kub tau 2 teev lossis ntau dua, uas feem ntau siv polymethacrylate lossis epoxy resin nrog cov qauv tshwj xeeb thiab amino resin, chlorinated paraffin ua lub hauv paus binder, nrog rau qib polymerization siab ammonium polyphosphate, dipentaerythritol, melamine ua lub kaw lus tiv thaiv hluav taws kub. Titanium dioxide, wollastonite thiab lwm yam khoom siv inorganic refractory ntxiv rau 200 # solvent roj ua cov khoom sib xyaw ua ke. Ntau yam qauv hlau sib dua, grids, thiab lwm yam, siv hom xim tiv thaiv hluav taws kub no rau kev tiv thaiv hluav taws kub. Vim yog cov txheej txheem tiv thaiv hluav taws kub ultra-thin no, kev siv cov txheej txheem tiv thaiv hluav taws kub tuab dua thiab nyias dua ntawm cov qauv hlau raug txo qis heev, uas txo tag nrho cov nqi ntawm qhov project, thiab ua rau cov qauv hlau tau txais kev tiv thaiv hluav taws kub zoo, thiab cov txiaj ntsig tiv thaiv hluav taws kub zoo heev.

Cov txheej txheem primer ntawm cov qauv hlau

2. Cov txheej txheem tiv thaiv hluav taws rau cov qauv hlau nyias

Cov txheej txheem tiv thaiv hluav taws xob ntawm cov qauv hlau uas muaj txheej tuab ntau dua 3 hli, tsawg dua lossis sib npaug rau 7 hli, muaj qee yam zoo nkauj, nthuav dav thiab tuab ntawm qhov kub siab, thiab qhov txwv tsis pub hluav taws kub yog li ntawm 2 teev. Hom txheej txheem tiv thaiv hluav taws xob no rau cov qauv hlau feem ntau yog tsim los ntawm cov polymer dej-raws li cov khoom siv hauv paus, thiab tom qab ntawd tsim los ntawm cov txheej txheem sib xyaw ntawm cov nplaim taws retardants, cov khoom ntxiv tiv thaiv hluav taws kub, cov fibers tiv thaiv hluav taws, thiab lwm yam, thiab nws cov hauv paus ntsiab lus tiv thaiv hluav taws kub zoo ib yam li hom ultra-nyias. Rau hom txheej txheem tiv thaiv hluav taws kub no, cov polymer dej-raws li yuav tsum tau xaiv yuav tsum muaj kev nplaum zoo, ruaj khov thiab tiv taus dej rau cov hlau substrate. Nws cov kho kom zoo nkauj zoo dua li cov txheej txheem tiv thaiv hluav taws kub tuab, qis dua cov txheej txheem tiv thaiv hluav taws kub ntawm cov qauv hlau ultra-nyias, thiab qhov txwv tsis pub hluav taws kub dav dav yog li ntawm 2 teev. Yog li ntawd, nws feem ntau siv rau hauv cov haujlwm tiv thaiv hluav taws kub ntawm cov qauv hlau uas muaj qhov txwv tsis pub hluav taws kub tsawg dua 2 teev, thiab kev tsim kho tsuag feem ntau siv. Hauv ib lub sijhawm, nws nyob hauv ib feem loj, tab sis nrog rau qhov tshwm sim ntawm cov hlau ultra-thin fireproof coatings, nws cov feem ntawm kev ua lag luam tau hloov maj mam.

3. Cov qauv hlau tuab uas tiv taus hluav taws

Cov txheej txheem hluav taws kub tuab yog hais txog cov txheej tuab ntau dua 7 hli, tsawg dua lossis sib npaug rau 45 hli, nto granular, me me, thermal conductivity tsawg, hluav taws kub txwv ntau dua 2 teev cov txheej txheem hluav taws kub. Vim tias cov txheej txheem hluav taws kub tuab feem ntau yog cov khoom inorganic, nws qhov kev ua haujlwm hluav taws ruaj khov thiab kev siv mus sij hawm ntev yog qhov zoo, tab sis cov khoom me me ntawm nws cov xim pleev xim loj, qhov tsos ntawm cov txheej txheem tsis sib xws, cuam tshuam rau qhov zoo nkauj ntawm lub tsev, yog li nws feem ntau siv rau kev tsim kho vaj tse zais cia. Hom txheej txheem hluav taws kub no siv cov nplaim granular ntawm cov khoom siv hauv hluav taws, qhov ceev yog me me, thermal conductivity tsawg lossis cov khoom siv hauv cov txheej txheem, uas ncua qhov kub nce ntawm cov hlau thiab tiv thaiv cov hlau. Cov txheej txheem tiv thaiv hluav taws no yog ua los ntawm cov khoom siv inorganic binder (xws li dej iav, silica sol, txhuas phosphate, refractory cement, thiab lwm yam), Tom qab ntawd nws yog sib xyaw nrog cov khoom siv inorganic sib xyaw adiabatic aggregate (xws li nthuav dav perlite, nthuav dav vermiculite, hiav txwv bouldering, ntab hlaws dai, ya tshauv, thiab lwm yam), cov khoom siv hluav taws kub retardant, cov tshuaj lom neeg thiab cov ntaub ntawv txhawb nqa (xws li txhuas silicate fiber, pob zeb wool, ceramic fiber, iav fiber, thiab lwm yam) thiab cov khoom sau, thiab lwm yam, uas muaj qhov zoo ntawm tus nqi qis. Kev txau feem ntau siv rau hauv kev tsim kho, uas yog qhov tsim nyog rau sab hauv tsev thiab sab nraum zoov zais cov qauv hlau nrog cov kev txwv tiv thaiv hluav taws ntau dua 2 teev, cov qauv hlau siab thiab cov qauv hlau Hoobkas ntau txheej. Piv txwv li, qhov txwv tiv thaiv hluav taws ntawm cov kem ntawm cov tsev siab, cov tsev lag luam dav dav thiab cov tsev pej xeem txhawb nqa ntau txheej kem yuav tsum ncav cuag 3 teev, thiab cov txheej txheem tiv thaiv hluav taws tuab yuav tsum tau siv los tiv thaiv lawv.

(2) cov qauv hlau anticorrosive xim

Cov txheej tiv thaiv xeb rau cov qauv hlau yog ib hom txheej tiv thaiv xeb tshiab rau cov qauv hlau uas tsim los ntawm cov roj-resistant anti-corrosion txheej. Cov xim muaj ob hom primer thiab top xim, ntxiv rau, nws qhov kev siv dav dua, thiab cov xim tuaj yeem hloov kho rau ntau yam xim raws li qhov xav tau. Cov txheej tiv thaiv xeb rau cov qauv hlau yog tsim rau cov dej phwj tuaj, dej hiav txwv, dej lag luam, roj av, kerosene, roj diesel dav hlau, roj thiab lwm yam tso tsheb hlau luam, roj, cov kav dej roj, Choj, grids, cov khoom siv fais fab thiab txhua yam khoom siv tshuaj lom neeg tiv thaiv xeb, kuj tseem siv tau rau cov chaw ua vaj tse tiv thaiv xeb.

Ua ntej, txhim kho qhov xwm txheej ntawm cov hlau: uas yog, kev kho mob alloy:

Muaj ntau tus kws tshawb fawb txawv teb chaws tau kawm txog kev cuam tshuam ntawm ntau yam khoom sib xyaw rau kev tiv thaiv xeb ntawm cov hlau rau dej hiav txwv. Nws pom tias cov hlau sib xyaw ua ke raws li Cr, Ni, Cu, P, Si thiab cov av tsis tshua muaj muaj cov khoom tiv thaiv xeb zoo heev, thiab ntawm lub hauv paus no, ntau cov hlau tiv thaiv xeb dej hiav txwv tau tsim. Txawm li cas los xij, vim muaj kev txiav txim siab txog kev lag luam thiab kev siv tshuab, cov ntsiab lus saum toj no tsis tau siv dav hauv cov hlau tiv thaiv xeb dej hiav txwv.

Qhov thib ob, kev tsim ntawm ib txheej tiv thaiv: uas yog, txheej txheej uas tsis yog hlau lossis hlau tiv thaiv:

Cov txheej tiv thaiv hlau feem ntau yog siv rau kev phosphating, oxidation thiab passivation ntawm cov hlau coated. Cov txheej tiv thaiv uas tsis yog hlau feem ntau yog txheej xim, yas, enamel, mineral roj thiab lwm yam rau ntawm qhov chaw hlau los tsim ib txheej tiv thaiv. Lub hom phiaj ntawm ob txheej tiv thaiv no yog cais cov khoom siv los ntawm kev sib cuag nrog dej hiav txwv, es tsis txhob cuam tshuam nrog dej hiav txwv, yog li tsim kev tiv thaiv.
