Iyo inodzivirira moto michina yesimbi chimiro chemoto machira

Chimiro cheSimbi chinovhara moto chinononoka kukwira kwekushisa kwesimbi mumoto kuburikidza nenzira dzakasiyana-siyana, kuve nechokwadi chekugadzikana kwechimiro pasi pekupisa kwakanyanya.

Iwo makuru ekudzivirira moto ndeaya anotevera:

Thermal Barrier Formation

• Intumescent Coatings: Kana yaiswa kune tembiricha yakakwira, iyo coating inokura kuita porous char layer, inodzivirira kupisa uye oxygen, zvichibva zvaderedza kukwira kwesimbi.
• Non-itumescent Coatings: Shandisa mafirita ane huwandu hwekupisa uye yakaderera yekupisa conductivity (semuenzaniso, aluminium hydroxide, magnesium hydroxide) kutora kupisa uye kugadzira insulating layer.
• Endothermic Reactions

• Heat Absorption kuburikidza neDecomposition: Mafirita akadai sealuminium hydroxide uye magnesium hydroxide anoora pasi pekupisa kwakanyanya, anotora kupisa uye kuderedza tembiricha yesimbi.
• Phase Shandura Kupisa Kunyura: Mamwe mafirita anotora kupisa kuburikidza nechikamu chekuchinja pakupisa kwakanyanya, kunonoka kukwira kwesimbi tembiricha.2Inert Gasi Kuburitswa

• Gasi Emission: Pakupisa kwakanyanya, iyo yekuputira inoora uye inoburitsa inert magasi (eg, nitrogen, kabhoni dhaikisaidhi), diluting oxygen concentration uye kudzvinyirira kupisa.Char Layer Dziviriro

• Char Formation: Intumescent coatings inoita dense char layer pakupisa kwakanyanya, kudzivirira simbi kubva pakupisa uye oxygen.
• Char Layer Kugadzikana: Iyo char layer inoramba yakagadzikana pasi pekupisa kwakanyanya, ichipa kuchengetedzwa kunoramba kuripo.
• Chemical Reactions

• Flame Retardant Effects: Zvidziviriro zvemoto (semuenzaniso, phosphorus-based, nitrogen-based) mukuputira zvinogadzira zvinhu zvinodzivirira moto pakupisa kwakanyanya, kudzvinyirira maitiro ekupisa.
• Chipingamupinyi Chemuviri

• Coating Ukobvu: Kuwedzera coating ukobvu kunowedzera insulation, kunonotsa tembiricha yesimbi kukwira.
• Dense Structure: Iyo yekuputira inoumba compact chimiro, inonyatso kuvharira kupisa uye oksijeni.
• Simbi yekumisikidza machira anoshandisa nzira dzakasiyana-siyana-yekupisa zvipingamupinyi, endothermic reactions, inert gasi kuburitswa, char layer kuchengetedza, kemikari, uye zvipingamupinyi zvemuviri - kunonoka kukwira kwesimbi panguva yemoto, kuve nechokwadi kugadzikana kwechimiro pasi pekupisa kwakanyanya. Nzira idzi dzinoshanda pamwe chete kuti dzipe dziviriro yemoto inoshanda.
• Ammonium Polyphosphate is a key product for intumescent coatings , usually working together with melamine and pentaerythritol . TF-201 is a popular grade for water based intumescent coating with good water stability in storage. More info., pls contact lucy@taifeng-fr.com
