Intumescent fireproof coating

Inogona kupatsanurwa muzvikamu zviviri zvinonyungudutsira uye mvura-yakavakirwa, iyo miviri miviri yejasi inosarudzwa nezvikamu zvemoto zvakangofanana, saka zvakaoma kutaura kuti misiyano yakawanda sei mukuita kwavo kwemoto, iyo inonyungudutsa yakasarudzwa kushandisa firimu. -kugadzira zvinhu. Solvent-based fireproof coating film-forming substances inowanzosarudzwa chlorinated rabha, pamusoro pelv vinyl, amino resin, phenolic resins, nezvimwewo, kushandiswa kwezvinonyungudutsa zvependi yekupfapfaidza sparse zvichingodaro. Mvura-based fireproof coating film-forming substances.

Non-itumescent fireproof coating

Iyo yekupfeka haina kuchinja vhoriyamu kana ichiiswa pamoto. Kunyanya, iyo yekuputira pachayo haibatike kana isingabatike, iyo inogona kudzivirira murazvo kubva pakupararira, uye kupfeka kunogona kuparadza magasi asingabatike pasi pechiito chekushisa kwepamusoro kana murazvo kudzikisa kuwanda kweokisijeni uye magasi anopisa ari mumhepo, kuitira kudzivirira zvinobudirira kana kudzoreredza kupisa. Uye zvakare, iko kupfekedza pakupisa kwakanyanya kana pasi pekuita kwemurazvo kunogona kuumba isingabatike inorganic glaze-yakafanana yekudzivirira layer inovhara pamusoro peiyo inopisa substrate kuparadzanisa iyo inopisa substrate uye kusangana kweokisijeni, kuitira kudzivirira kana kuderedza kuitika kwekupisa kwemoto, uye mune imwe nguva yenguva ine imwe dhigirii yekupisa kupisa.

Zvinoenderana neiyo nzira yekudzivirira moto, yakakamurwa kuita intumescent uye isina-intumescent simbi chimiro chekudzivirira moto coating; isina-intumescent simbi yakagadzirwa nemoto coating inoreva iyo simbi chimiro chekudzivirira moto coating iyo iyo coating haina kuwedzera uye furo pakupisa kwakanyanya, uye inova inodzivirira moto uye inodzivirira kupisa-inodzivirira layer pachayo.

Zvinoenderana neazvino chiyero chenyika GB14907-2018, mvura-yakavakirwa / yakanyungudika-yakavakirwa isiri-intumescent yakajairwa / yakakosha simbi chimiro chekudzivirira moto. Ukobvu hwehuputi hweisina-intumescent simbi chimiro chekudzivirira moto haifanire kunge iri pasi pe15㎜.

Isiri-intumescent simbi chimiro chekudzivirira moto yekumisikidza moto insulation musimboti ndeyekuti iyo yekupfekedza haiite shanduko yevhoriyamu kana ichiiswa pamoto, asi iyo yekupisa conductivity yejasi yakadzikira kwazvo, iyo inononoka kukurumidza kwekutamisa kupisa kune insured substrate. uye kupfekedzwa kwechifukidzo chemoto pachayo hachigoni kupisa, uye chinoshanda sechidziviriro uye chinodzivirira kupisa kwekushisa kwezvikamu zvesimbi, izvo zvinodzivirira murazvo uye kupisa kwepamusoro kubva pakurwisa zvakananga zvikamu zvesimbi.  

Pane zvimwe zvikamu mujasi izvo zvinosangana nemumwe kana moto kuburitsa isiri-gasi muviri inzira yekupisa kunyura kuita, asi zvakare inopedza kupisa kwakawanda, izvo zvinobatsira kudzikisa tembiricha yehurongwa, saka. iyo yekudzivirira moto inoshamisa, uye inotamba yakanyanya kudzivirira moto uye kupisa kwekudzivirira kwesimbi. Uye zvakare, rudzi urwu rwesimbi chimiro chekuvhara moto chinoiswa pasi pemoto kana chivharo ichichinja kuita glazed inodzivirira layer, iyo inogona kuita basa mukuparadzanisa okisijeni, kuitira kuti okisijeni irege kudzivirirwa neinopfuta.

WBM-01 yekupedzisa-yemhando yekudzivirira moto yekubatisa yekuvaka mirairo yekupedzisa-mhando yekuputira moto ndeyemvura-yakavakirwa huni chimiro chekudzivirira moto, ne "National Quality Supervision uye Inspection Center yeFixed Fire Extinguishing Systems uye Fire-Resistant Components" bvunzo, iyo yemuviri uye kemikari. zvimiro zveyero, kuita kwemoto kweyero yekutanga. Iwo tekinoroji maitiro echigadzirwa anoenderana neGB12441-2005 standard. Kuburikidza nekushandiswa kwezvigadzirwa zvemhando yepamusoro uye maitiro akasarudzika ekugadzira, nguva yekudzivirira moto ≥ maminitsi makumi maviri, kuzadzisa zviyero zvenyika, kana murazvo uchipisa pendi, kuumbwa kwespongy charcoal layer pane substrate kune kupisa kwekupisa kutonhora uye kuparadzaniswa kwependi. basa remhepo, iro rinogona kuderedza kukurumidza kwekupararira kwemurazvo pamusoro pezvinhu zvakaputirwa, zvinobudirira kudzivirira kukurumidza kupararira kwemoto kudzivirira kupisa kwehuni kuti uwane chinangwa chekupisa. Iyo pendi yekuputira, kupupa uye kuwedzera kana moto, ichigadzira chipanje-senge senge yemoto insulation layer uye yekuzviparadzanisa nemoto sosi, inogona kunyatso chengetedza chigadziko chinopisa mune imwe nguva yenguva, uye inogona kushandiswa zvakanyanya muindasitiri uye yevagari kuvaka kwemapuranga. zvikamu zvemaitiro, mapaneru anopfuta uye flue, madhaivhu emhepo uye kumwe kudzivirira kwemoto.
