simbi chimiro coatings pendi

Simbi imhando yeisina-kupisa zvinhu zvekuvaka, ine seismic, kukotama uye humwe hunhu. Mukushanda kwekushanda, simbi haingogone kuwedzera huwandu hwezvivakwa, asiwo inosangana nezvinodiwa zveaesthetic modeling yekugadzira dhizaini. Inodzivirirawo kukanganisa kwekuti zvinhu zvekuvaka zvakadai sekrete hazvigoni kukotama uye kutambanudza. Naizvozvo, simbi yakafarirwa neindasitiri yekuvaka, single-storey, multi-storey, skyscrapers, mafekitori, matura, makamuri ekumirira, horo dzekubva uye mamwe simbi zvakajairika. Kuti tidzidze kubva kune mumwe nemumwe, kushandiswa kweiron structure coatingsuyesimbi primerpendi yakakosha.

Kusarudzwa kwesimbi yakagadzirwa nesimbi

Simbi chimiro machira anonyanya kuve nemhando mbiri dzesimbi dhizaini mabhandi emoto uye simbi chimiro anti-corrosion coatings.
(A) simbi chimiro chemoto pendi

1. Ultra-yakaonda structural fireproof coating

Ultra-yakaonda simbi chimiro chekudzivirira moto chinoreva kukora mukati me3 mm (kusanganisira 3 mm), iyo yekushongedza mhedzisiro yakanaka, inogona kuwedzera pakupisa kwepamusoro, uye muganho wekupokana nemoto unowanzo mukati me2 h yesimbi inodzivirira moto. Iyi mhando yesimbi yakagadzirwa nemoto retardant coating inowanzo solvent-based system, ine simba repamusoro rekubatanidza, kumira kwemamiriro ekunze kwakanaka uye kuramba kwemvura, kuenzana kwakanaka, maitiro akanaka ekushongedza; Kana yapiswa, inokura zvishoma nezvishoma uye ichipupuma furo kuita dende uye rakaomarara rekudzivirira moto. Iyo isingapindi moto layer ine yakasimba-inodzivirira moto midziyo, inononoka kukwira kwetembiricha yesimbi uye inodzivirira zvinobudirira zvikamu zvesimbi. Iko kuvakwa kweyekupedzisira-yakatetepa yakawedzera simbi chimiro chekuputira moto chinogona kupfapfaidzwa, kubhurashwa kana kukungurutswa, chinowanzo shandiswa mukupikiswa kwemoto zvinodiwa mukati me2 h pachivakwa chesimbi. Pakave nemhando nyowani dzeakanyanya-mutete simbi chimiro chekudzivirira moto nekudzivirira moto kwemaawa maviri kana kupfuura, ayo anonyanya kushandisa polymethacrylate kana epoxy resin ine yakakosha dhizaini uye amino resin, chlorinated parafini seyakadzika binder, ine yakakwira polymerization degree ammonium polyphosphate, dipentaerythritol, melamine seyakadzoreredza moto system. Titanium dioxide, wollastonite uye zvimwe inorganic refractory zvinhu zvinowedzerwa ku200# solvent mafuta sechinhu chinonyungudutsa. Zvimiro zvakasiyana-siyana zvesimbi, magridi, nezvimwewo, shandisa rudzi urwu rwependi yemoto kudzivirira moto. Nekuda kweiyo yekupedzisira-yakaonda yekuputira yerudzi urwu rwekudzoreredza moto, kushandiswa kwesimbi yakaonda uye yakaonda simbi chimiro chinodzikisira moto chinodzikisira zvakanyanya, izvo zvinoderedza mutengo wakazara wepurojekiti, uye inoita kuti chimiro chesimbi chiwane kudzivirirwa kwemoto kunoshanda, uye mhedzisiro yekudzivirira moto yakanaka kwazvo.

2. Kuvhara kwemoto kunopisa kune yakaonda simbi chimiro

Iyo yakaonda-yakavharwa simbi chimiro chekudzivirira moto chinoreva simbi chimiro chekudzivirira moto chifukidziro icho ukobvu hwekufukidzira kwakakura kupfuura 3mm, isingasviki kana kuenzana ne7mm, ine imwe yekushongedza mhedzisiro, inowedzera uye inokora pakupisa kwepamusoro, uye muganho wekudzivirira moto uri mukati me2 h. Rudzi urwu rwekuputira nemoto wechimiro chesimbi chinowanzo umbwa nepolymer yakakodzera mvura-yakavakirwa sechinhu chepasi, uyezve inoumbwa neyakaumbwa sisitimu yezvinodzoreredza moto, zvinorebesa moto zvinowedzera, tambo dzisingadziviriri moto, nezvimwewo, uye nheyo yayo yekudzivirira moto yakafanana neyokupedzisira-yakaonda mhando. Kune rudzi urwu rwekuvhara moto, mvura-based polymer inoda kusarudzwa inofanira kuva nekunamatira kwakanaka, kusimba uye kudzivirira mvura kune substrate yesimbi. Kushongedzwa kwayo kuri nani pane machira akakora asingapindire moto, yakaderera kune yekupedzisira-yakatetepa simbi chimiro chekudzivirira moto machira, uye yakajairika kumisa moto muganho uri mukati me2 h. Naizvozvo, inowanzoshandiswa musimbi chimiro chekudzivirira moto mapurojekiti ane isingasviki 2 h moto wekudzivirira muganho, uye kupfapfaidza kuvaka kunowanzoshandiswa. Mune imwe nguva, yakatora chikamu chikuru, asi nekubuda kwe-ultra-thin simbi chimiro chekudzivirira moto, chikamu chayo chemusika chakatsiviwa zvishoma nezvishoma.

3. Gobvu simbi chimiro chinoputira moto

Gobvu simbi chimiro moto retardant coating inoreva coating ukobvu yakakura kupfuura 7 mm, isingasviki kana kuenzana 45 mm, granular pamusoro, diki density, yakaderera kupisa conductivity, moto kuramba muganho anopfuura 2 h simbi chimiro moto retardant coating. Sezvo kuumbwa kwemachira akakora anodzikisira moto anonyanya kuve zvinhu zvisiri izvo, kuita kwayo kwemoto kwakagadzikana uye kushandiswa kwenguva refu kwakanaka, asi zvidimbu zvependi yacho zvakakura, kutaridzika kwejasi hakuna kuenzana, kunokanganisa kunaka kwechivakwa, saka inonyanya kushandiswa kune yekuvaka yakavanzika engineering. Rudzi urwu rwekupisa runodzoreredza moto runoshandisa granular pamusoro pezvinhu zviri mumoto, density idiki, thermal conductivity yakadzikira kana kupisa kunyura kwezvinhu zviri mujasi, izvo zvinononoka kukwira kwekushisa kwesimbi uye kuchengetedza simbi. Rudzi urwu rwekuputira nemoto rakagadzirwa neakakodzera inorganic binder (senge girazi remvura, silica sol, aluminium phosphate, refractory simende, nezvimwewo), Zvino inosanganiswa neinorganic lightweight adiabatic aggregate zvinhu (senge yakawedzera perlite, yakawedzera vermiculite, gungwa bouldering, inoyangarara mabheji, nyuchi dzemoto, nyuchi, nyuchi dzemoto). zvekusimbisa zvinhu (zvakadai sealuminium silicate fiber, rock wool, ceramic fiber, glass fiber, etc.) uye mafirita, nezvimwewo, izvo zvine zvakanakira mutengo wakaderera. Kupfapfaidza kunowanzoshandiswa mukuvaka, iyo inokodzera mukati uye kunze yakavanzwa zvivako zvesimbi zvine miganhu yekudzivirira moto inopfuura 2 h, yakakwirira-inokwira yose-simbi zvivako uye multi-storey factory steel structures. Semuenzaniso, muganho wekudzivirira moto wembiru dzezvivakwa zvepamusoro-soro, zvivakwa zvakajairika zvemaindasitiri uye zvehurumende zvinotsigira mbiru dzematanho akawanda dzinofanirwa kusvika 3h, uye iyo yakakora isingadzivirirwe nemoto inofanira kushandiswa kuvadzivirira.

(2) simbi chimiro anticorrosive pendi

Anti-corrosion coating yechimiro chesimbi rudzi rutsva rwe-anti-corrosion coating yesimbi chimiro chakagadzirwa pahwaro hwemafuta-resistant anti-corrosion coating. Iyo pendi yakakamurwa kuva mhando mbiri dzeprimer uye pendi yepamusoro, mukuwedzera, huwandu hwayo hwekushandisa hwakakura, uye pendi inogona kugadziridzwa kune akasiyana mavara zvichienderana nezvinodiwa. Simbi chimiro anti-corrosion coating inokodzera tsvina, mvura yegungwa, mvura yeindasitiri, peturu, parafini, dhiziri jet mafuta, gasi uye mamwe matangi ekuchengetedza, oiri, magasi mapaipi, Bridges, grids, magetsi emidziyo uye marudzi ese emakemikari midziyo yekudzivirira ngura, inogona zvakare kushandiswa kune kongiri zvivakwa kudzivirira ngura.

Kutanga, kunatsiridza chimiro chesimbi: ndiko kuti, kurapwa kwealloy:

Nyanzvi dzakawanda dzekune dzimwe nyika dzakadzidza pesvedzero yezvinhu zvakasiyana-siyana zvinosanganiswa nesimbi pakusaora kwesimbi kumvura yomugungwa. Inowanikwa kuti alloy steels yakavakirwa paCr, Ni, Cu, P, Si uye isingawanzo pasi ine yakanakisa anti-corrosion zvivakwa, uye nechikonzero ichi, akatevedzana emvura yegungwa anodzivirira simbi akagadzirwa. Nekudaro, nekuda kwekufunga kwehupfumi uye tekinoroji, zvinhu zviri pamusoro hazvishandiswe zvakanyanya mumasimbi emvura egungwa asingadziviriri.

Chechipiri, kuumbwa kwechidziviriro chekudzivirira: ndiko kuti, kupfeka kusina simbi kana simbi inodzivirira:

Iyo simbi inodzivirira layer inonyanya kushandiswa phosphating, oxidation uye passivation kurapwa kwesimbi yakavharwa. Iyo isiri-metallic inodzivirira layer inonyanya kupfekedza pendi, mapurasitiki, enamel, mineral grease uye zvichingodaro pamusoro pesimbi yesimbi kuti iite danda rekudzivirira. Chinangwa chezvikamu zviviri izvi zvekudzivirira ndechekuparadzanisa nheyo kubva pakusangana nemvura yegungwa, panzvimbo yekuita nemvura yegungwa, nokudaro kugadzira dziviriro.
