Isebenza njani i-ammonium polyphosphate kunye ne-melamine kunye ne-pentaerythritol kwiingubo zokwaleka?

Kwizinto zokugquma ezingatshiyo, intsebenziswano phakathi kwe-ammonium polyphosphate, i-pentaerythritol, kunye ne-melamine ibalulekile ekufezekiseni iipropati ezinqwenelekayo zokumelana nomlilo.

I-Ammonium polyphosphate (i-APP) isetyenziswa ngokubanzi njenge-flame retardant kwizicelo ezahlukeneyo, kubandakanywa neengubo ezingenamlilo.Xa ibonakaliswe kumaqondo okushisa aphezulu, i-APP ikhupha i-phosphoric acid, ehambelana ne-radicals yamahhala eveliswa ngexesha lenkqubo yokutsha.Le ndlela yokusabela ikhokelela ekwakhiweni kwe-char layer eshinyeneyo nekhuselayo, esebenza njengomqobo wokuthintela ubushushu kunye nokuhanjiswa kweoksijini, ngaloo ndlela icothisa ukusasazeka kwamadangatye.

I-Pentaerythritol yikhompawundi ye-polyol esebenza njengomthombo wekhabhoni kunye ne-arhente yokutshaja.Iyabola xa ibonakaliswe kubushushu, ivelise iikhompawundi eziguqukayo ezifana nekharbon diokside kunye nomphunga wamanzi.Ezi zixhobo eziguquguqukayo zinciphisa ukuxinwa kwe-oksijeni kwaye zinqande ukusabela kokutsha, ngelixa i-carbon residue eseleyo yenza i-char layer ezinzileyo ekhusela i-substrate ekugqithiseni ukushisa.

I-Melamine, i-nitrogen-rich compound, igalelo kwiipropati zokumelana nomlilo zengubo.Xa i-melamine ishushu, ikhupha igesi ye-nitrogen, edlala indima ebalulekileyo ekuthinteleni umlilo.I-nitrogen ekhutshiweyo inceda ukususa i-oksijini, ukunciphisa umoya we-oxidizing ojikeleze amadangatye, kwaye ngaloo ndlela inqanda inkqubo yokutsha.

Ngokudibeneyo, intsebenziswano phakathi kwezi zinto idibanisa iziphumo ze-phosphorus, i-carbon, kunye ne-nitrogen ukunyusa ukuxhathisa umlilo kwiingubo.I-ammonium polyphosphate isebenza njenge-flame retardant, yenza i-char layer ekhuselayo.I-Pentaerythritol inegalelo kwi-carbonization, ivelisa i-char eninzi ukukhusela ubushushu.Ekugqibeleni, i-melamine ikhupha igesi yenitrogen ukudala umoya ocima umlilo.Ngokusebenza kunye, ezi zinto zintathu zilibazisa ngokufanelekileyo ukutshisa kwaye zicothise isantya sokusasazeka kwedangatye, zenza iingubo ezingatshiyo zikhuseleke kwaye zikhuseleke ngakumbi kwiingozi zomlilo.

Shifang Taifeng New Flame Retardant Co., Ltdngumvelisi oneminyaka engama-22 yamava okhethekileyo kwimveliso ye-ammonium polyphosphate retardants flame, iimveliso zethu zithunyelwa ngokubanzi phesheya kolwandle.

Ummeli wethu idangatye retardantTF-201i-eco-friendly kwaye inoqoqosho, inesicelo esivuthiweyo kwiingubo ze-intumescent, i-textile back coating, iplastiki, umthi, intambo, izinto zokuncamathelisa kunye ne-PU foam.

Ukuba ufuna ukwazi okungakumbi, nceda uqhagamshelane nathi.
