Kapangidwe chitsulo chophunzitsira utoto

Zitsulo ndi mtundu wa zinthu zomangira zopanda moto, zimakhala ndi sema, kuwerama komanso zina. Pogwiritsa ntchito, zitsulo sizimangokulitsa katunduyo kuthekera kwa nyumba, komanso kukwaniritsa zosowa za zokongoletsa zokongola za kapangidwe ka zomangamanga. Zimapewanso zilema zomwe zimalimbikitsa zida monga konkriti sizingatheke ndikutambasulira. Chifukwa chake, chitsulo chalandilidwa ndi makampani omanga, osasungidwa, osakhazikika, ma skicycrapers, maofesi, zipinda zina zotsala ndi zitsulo zina ndizofala. Kuti muphunzire kwa wina ndi mnzake, kugwiritsa ntchitoKapangidwe ka chitsulondichitsulo choyambirirautoto ndikofunikira.

Gulu la mawonekedwe achitsulo

Kapangidwe chitsulo chophimbira kumakhala ndi mitundu iwiri ya zitsulo zoyaka moto ndi chitsulo chosiririka.
(A) utoto wachitsulo

Ultra-woonda wowonda moto wokutira umatanthawuza makulidwe mkati mwa 3 mm (kuphatikizapo 3 mm), zokongoletsera ndi zabwino, zimatha kukula pa kutentha kwa zitsulo zokutidwa. Mtundu wamtunduwu wolumikizira moto nthawi zambiri umasungunuka, ndi mphamvu yayikulu, kukana kwa nyengo yabwino ndi kukana madzi, mawonekedwe abwino, mawonekedwe abwino; Ikayaka moto, imakula pang'onopang'ono ndi chinsalu kuti ipange mtundu wowuma komanso wolimba moto wowuma. Wosanjikiza wamoto wamoto ali ndi katundu wolimba wa moto wa moto watha, akuchedwetsa kutentha kwa chitsulo komanso kuteteza zigawo zitsulo. Kupanga kwa mawonekedwe owonda a ultra-okutira kumatha kuthiridwa, kugwedezeka kapena kugubuduzika, nthawi zambiri kumagwiritsidwa ntchito pamoto wofunikira pa 2 h pa mawonekedwe a nyumba. Pakhala mitundu yatsopano ya mawonekedwe opyapyala owuma ndi kukana kwa moto wa 2 h kapena kupitilira apo, omwe amagwiritsa ntchito polymethacry Dipentaierythmitol, melamine ngati moto woyatsira moto. Titanium Dioxide, Wollastonite ndi zinthu zina zodziwika bwino zimawonjezeredwa ku 200 # solunt mafuta ngati zosungunulira. Mapangidwe osiyanasiyana achitsulo, grids, etc., gwiritsani ntchito utoto wamtunduwu kutetezedwa ndi moto. Due to the ultra-thin coating of this kind of fire retardant coating, the use of thicker and thinner steel structure fire retardant coating is greatly reduced, which reduces the total cost of the project, and makes the steel structure get effective fire protection, and Kuteteza moto ndikwabwino kwambiri.

2. Moto wokhotakhota kuti akhale wopanda mawonekedwe

The thin-coated steel structure fireproof coating refers to the steel structure fireproof coating whose coating thickness is greater than 3mm, less than or equal to 7mm, has a certain decorative effect, expands and thickens at high temperature, and the fire resistance limit is within 2 h. This kind of fireproof coating for steel structure is generally composed of a suitable water-based polymer as the base material, and then composed of a composite system of flame retardants, fire retardant additives, fire-resistant fibers, etc., and its fire prevention Mfundo ndizofanana ndi mtundu wowonda. For this type of fireproof coating, the water-based polymer required to be selected must have good adhesion, durability and water resistance to the steel substrate. Its decoration is better than thick fireproof coatings, inferior to ultra-thin steel structure fireproof coatings, and the general fire resistance limit is within 2 h. Therefore, it is commonly used in steel structure fire protection projects with less than 2 h fire resistance limit, and spray construction is often used. In one period, it occupied a large proportion, but with the emergence of ultra-thin steel structure fireproof coatings, its market share was gradually replaced.

Makina ang'onoang'ono azithunzithunzi amatchula makulidwe okutira ndi ochulukirapo kuposa 7 mm, ocheperako kapena ocheperako, kuchepa kwa madzi ochulukirapo, h Popeza kapangidwe ka zokutira zamoto zokulirapo ndizopangira zinthu zachilengedwe, magwiridwe ake amoto ndi okhazikika komanso okhazikika Mnyumbayo, motero amagwiritsidwa ntchito kwambiri pa ntchito yobisika. Zojambula zamtunduwu zolimbitsa thupi zimagwiritsa ntchito ma granalar pamtunda wa pamoto, kachulukidwe ndi kakang'ono, kutentha kwamitengo kumakhala kotsika kapena kuyamwa kutentha kwa chitsulo, komwe kumachepetsa kutentha kwa chitsulo ndikuteteza chitsulo . Mtundu wamtunduwu wopangidwa ndi moto wopangidwa ndi nthambi yoyenera (monga galasi yamadzi, silika ya aluminiya, etc.), kenako imakulitsa perculilite, Nyanja Kupanga mikanda, kuyandama phulusa, etc.), zowonjezera zowonjezera, mapangidwe a nthomba mtengo wotsika. Spraying is often used in construction, which is suitable for indoor and outdoor concealed steel structures with fire resistance limits of more than 2 h, high-rise all-steel structures and multi-storey factory steel structures. For example, the fire resistance limit of the columns of high-rise civil buildings, general industrial and civil buildings supporting multi-layer columns should reach 3h, and the thick fireproof coating should be used to protect them.

(2) Kapangidwe kakang'ono utoto wa anticorosive

Anti-Prerusion wokutidwa ndi mtundu watsopano wa anti-purrussion wokutidwa ndi chitsulo chophatikizika pamaziko a anti-kutupa. Utoto umagawidwa m'magulu awiri ndi utoto wapamwamba, kuphatikiza apo, kugwiritsa ntchito kwake kuli konse, ndipo utoto umatha kusinthidwa kukhala mitundu yosiyanasiyana malinga ndi zosowa zosiyanasiyana malingana ndi zosowa. Zojambula zachitsulo zokhala ndi zokongoletsera zam'madzi ndizoyenera kuwonongeka, madzi am'madzi, madzi a mafakitale, mafuta, milatho, milatho yam'madzi ndi mitundu yonse yamankhwala Kutetezedwa, kungakhalenso kugwiritsidwa ntchito kwa zokongoletsa zokongoletsa.

Choyamba, sinthani mtundu wachitsulo: ndiye, chithandizo cha Aloy:

Ophunzira ambiri kudziko akunja aphunzirapo kanthu kwa zinthu zosiyanasiyana zoyatsira zinthu zosakanikirana ndi zitsulo za madzi am'madzi. Amapezeka kuti chitsulo chokhazikika chokhazikitsidwa ndi Cr, NI, CU NDI GAOTOMODZI YAULERE, ndipo pamaziko am'madzi ogonjetsedwa a nyanja adapangidwa. Komabe, chifukwa cha malingaliro azachuma komanso auterino, zinthu zomwe zili pamwambazi sizigwiritsidwa ntchito kwambiri m'madzi ogonjetseka a nsomba.

Chachiwiri, mapangidwe a osanjikiza: ndiye kuti, akukutirani zitsulo kapena chitsulo choteteza:

Chitsulo choteteza chizithunzi chimagwiritsidwa ntchito kwambiri pankhani ya ma phosphat, oxidation ndi mankhwala othandizira azitsulo. Chosanjikiza chosatetezera chimakhala chophimba utoto, pulasitiki, enamel, mankhwalawo komanso otero pa chitsulo kuti apange malo oteteza. Cholinga cha zigawo ziwirizi ndikupatula maziko a maziko kuchokera ku madzi am'madzi, m'malo mobwereza madzi am'madzi, motero ndikuteteza

Zambiri zaife

Kampani yathuzakhala zikutsatira "sayansi ndi ukadaulo, zabwino, zowona mtima, ntchito zapamwamba za LS0900L: .Monga katswiri wazaka zaluso, titha kupereka zitsanzo kwa makasitomala omwe akufuna kugula, ngati mukufuna utoto wamtundu uliwonse, chonde titumizireni.
