Indima ePhambili yeI-Ammonium PolyphosphatekwiiNgqungquthela eziBamba uMlilo: Iziphumo zeSynergistic kunye neMelamine kunye nePentaerythritol

 I-ammonium polyphosphate(I-APP) isebenza njengenxalenye engundoqo ekuqulunqweni kwale mihlaIingubo ezithintela umlilo, enikela ukhuseleko olukhethekileyo kwisisongelo somlilo. Iimpawu zayo ezikhethekileyo, xa zidityaniswe nezinye izithako eziphambili ezifana ne-melamine kunye ne-pentaerythritol, zenza i-synergy enamandla eyandisa kakhulu ukusebenza komlilo we-coating.

Njengomthomalaliso wokuqala wokunqanda amadangatye,i-ammonium polyphosphateisebenza ngeendlela ezininzi. Emva kokuvezwa kumaqondo obushushu aphezulu, ibola kwaye ikhuphe i-asidi ye-phosphoric, ethi emva koko iphendule kunye ne-substrate ukuze yenze i-char layer ekhuselayo. Lo maleko we-char usebenza njengomqobo, ukuthintela ukuvutha ngakumbi kunye nokudluliselwa kobushushu. Ukongezelela, ukukhutshwa kweegesi ezingenakutsha, ezifana ne-ammonia kunye nomphunga wamanzi, kunceda ukunciphisa i-oxygen concentration ejikeleze izinto ezivuthayo, ngakumbi ukucinezela amadangatye.

Ngelixa i-ammonium polyphateralone isebenza kakhulu iyodwa, ukusebenza kwayo kungaphuculwa ngakumbi ngokongezwa kwe-melamine kunye ne-pentaerythritol. I-Melamine inegalelo ekubunjweni kwe-char layer eyomelele ngakumbi kwaye izinzile ngokubonelela ngomxholo we-nitrogen owongezelelweyo. Le nitrogen ayigcini nje ukwandisa inani lerhasi engatshiyo ekhutshiweyo kodwa ikwakhuthaza ukudityaniswa komnqamlezo we-char, iyenza ikwazi ukumelana nokuqhekeka.

I-Pentaerythritol, kwelinye icala, idlala indima ebalulekileyo ekuphuculeni iipropathi ezibonakalayo ze-coating retardant. Njengeplastiki, iphakamisa ukuguquguquka kunye nokubambelela kwengubo, iqinisekisa ukugubungela okungcono kunye nokuqina. Ngaphezu koko, i-pentaerythritol isebenza njengomgqugquzeli we-char, iququzelela ukwakheka kwe-char layer engqindilili kwaye eqhubekayo ekhusela ngokufanelekileyo izinto ezisisiseko kwidangatye.

Indibaniselwano ye-synergistic yei-ammonium polyphosphate, i-melamine, kunye ne-pentaerythritol kwi-coating retardant ye-fire-retardant iphumela kwisisombululo esisebenzayo nesithembekileyo sokukhusela umlilo. Esi sithathu sinamandla asiboneleli nje kuphela ukungabikho komlilo obalaseleyo kodwa kwakhona kunika iipropati eziphuculweyo zomzimba, okwenza kube lukhetho olufanelekileyo kuluhlu olubanzi lwezicelo.

Isishwankathelo,i-ammonium polyphosphateibalasele njengomdlali obalaseleyo kwiingubo ezithintela umlilo, kunye neziphumo zayo ezimangalisayo ze-synergistic kunye ne-melamine kunye ne-pentaerythritol iphucula ngakumbi ukusebenza kwayo. Le ndibaniselwano yezithako iqinisekisa ukuba i-coating inika ukhuseleko olufanelekileyo kwiingozi zomlilo, ukukhusela ubomi kunye nepropati.

Sichuan Taifeng New Flame Retardant Co.,Ltdyingcalii-ammonium polyphosphateumenzi eTshayina oneminyaka engama-22 yamava. I-APP TF-201 yimveliso edumileyo nevuthiweyo eyamkelwa yi-EU, India, Southeast Asia.
