Xa kufikwa ekukhuseleni umlilo, ii-intumescent coats zidlala indima ebalulekileyo ekuthinteleni ukusasazeka komlilo nokukhusela izakhiwo ekonakalisweni bubushushu. Ezi -coats zenzelwe ukwanda xa zichatshazelwa ngumlilo kwaye zenze umaleko omkhulu wamalahle, zibonelela ngomqobo kwi-substrate engaphantsi kwaye zinciphise ukusasazeka kwamalangatye. Isithako esiphambili esinokuphucula ukusebenza kwee-intumescent coats kukongeza ii-cenospheres njengezahlulo.
Ii-cenospheres zilula, zi-ceramic microspheres ezingenanto, ezaziwa ngokuba namandla okuphucula ukumelana nomlilo kunye neempawu zokukhusela izinto ezahlukeneyo. Xa zisetyenziswa njengezizalisi kwiingubo ezingaphakathi kwe-tumescent, ii-cenospheres ezingenanto zinokuzisa utshintsho olukhulu kunye nophuculo olunokunceda ekukhuseleni umlilo ngcono.
Kutheni ii-microspheres ezingenanto zisetyenziswa njengezizalisi kwiingubo ze-intumescent?
IiCenospheres zisetyenziswa kakhulu kwiifomyula zokugquma ezingaphakathi kwesisu ngenxa yeempawu zazo ezizodwa. Njengee-microspheres ezingenanto, zinokunciphisa ngokufanelekileyo uxinano lwengubo ngaphandle kokuchaphazela amandla ayo oomatshini. Le propati ilula ibangela ukuba ingubo yenze umaleko we-char otyebileyo nofanayo xa ubekwe emlilweni, ngaloo ndlela wonyusa ukumelana kwayo nomlilo.
Ukongeza, ii-microspheres ezingenanto zineempawu ezintle zokuthintela ubushushu, ezinceda ekunciphiseni ukudluliselwa kobushushu ngexesha lomlilo. Olu khuselo lunceda ukugcina ukuthembeka kwe-substrate engaphantsi, luthintele umonakalo wesakhiwo, kwaye lunciphise ukusasazeka kwamalangatye. Ukongeza, imilo engqukuva yeentsimbi ezingenanto ivumela ukupakisha okungcono kwi-matrix yepeyinti, ngaloo ndlela iphucula ukusasazeka kunye nozinzo.
Utshintsho kunye noPhuculo ekongezeni iiCenospheres kwiipeyinti ze-Intumescent
Ukongezwa kwee-microspheres ezingenanto njengezizalisi kwiingubo ezingaphakathi kwe-tumescent kuzise utshintsho kunye nophuculo oluphucule ukusebenza komlilo ngokubanzi. Okokuqala, ukongezwa kwee-microspheres ezingenanto kunciphisa uxinano yepeyinti, okwenza kube lula ukuyisebenzisa. Oku kwenza kube lula ukuyisebenzisa kwaye kuqinisekisa ukugqunywa okungcono, nto leyo ekhokelela ekuthintelweni komlilo okusebenzayo ngakumbi.
Ukongeza, iipropati zokuthintela ubushushu bee-microspheres ezingenanto ziyanceda ukuphucula ukusebenza kobushushu iingubo ezigqumayo. Umaleko wamalahle owakhekayo xa utshayelwa ngumlilo uba mkhulu kwaye ungatshisi kakhulu, nto leyo enika ukhuseleko oluphuculweyo kwisiseko esingaphantsi. Oku kuthetha ukuba ukumelana nomlilo okuphezulu kunye nokukhusela umlilo ixesha elide, izinto ezibalulekileyo ekukhuseleni izakhiwo kunye nezakhiwo.
Ukongeza, ukusetyenziswa kwe ii-cenospheres ezingenanto Kwizinto zokugquma ezingaphakathi kwesisu kudala ukunamathelana okungcono kunye nokudibana ngaphakathi kwe-matrix yokugquma. Imilo eyingqukuva kunye nokusasazwa kobukhulu bee-cenospheres ezifanayo kukhuthaza ukusasazeka okulinganayo ngaphakathi kwengubo, okubangela uzinzo oluphuculweyo kunye nomqobo womlilo onamandla. Olu manyano oluphuculweyo luqinisekisa ukuba umaleko wamalahle uhlala ungaguquki kwaye ubonelela ngokhuseleko oluqhubekayo ekusasazekeni kwamalangatye.
Ukusebenzisa ii-cenospheres kwiingubo ezingaphakathi kwe-tumescent ukuphucula ukhuseleko lomlilo
Ngamafutshane, ukusetyenziswa kwee-hollow microspheres njengezizalisi kwiingubo ze-intumescent kunika iingenelo ezininzi kwaye kunokuphucula kakhulu iimpawu zokukhusela umlilo. Ngokusebenzisa iimpawu ezikhethekileyo zee-hollow microspheres, ezinje ngokukhanya kwazo, amandla okukhusela, kunye nokusasazwa okuphuculweyo, ukusebenza kweengubo ze-intumescent kunokuphuculwa ukuze kubonelelwe ngokumelana nomlilo okuphezulu kunye nokhuseleko.
Xa ujonge ukuphucula ukusebenza komlilo kwesakhiwo, indima ebalulekileyo ii-cenospheres Kufuneka kuqwalaselwe indlela esebenza ngayo i-intumescent coatings. Ngokufaka ii-microspheres kwezi coatings, kunokwenziwa umqobo womlilo osebenzayo nothembekileyo, onciphisa ukusasazeka kwamalangatye kwaye unciphise umngcipheko wokonakala kwesakhiwo.
Njengoko imfuno yezisombululo zokukhusela umlilo eziphucukileyo iqhubeka ikhula, ukufakwa kwee-microspheres ezingenanto kwiingubo ze-intumescent kunika amathuba amahle okuphucula imigangatho yokhuseleko lomlilo kwiindlela ezahlukeneyo zoshishino nezorhwebo. Ngokwamkela le ndlela intsha, amashishini kunye namashishini anokuqinisa izakhiwo zawo ngokuchasene nezisongelo zomlilo kwaye abeke phambili ukhuseleko lwabantu kunye nempahla.
Ukufaka ii-cenospheres kwiingubo ezingaphakathi kwe-tumescent lutyalo-mali olusebenzayo nolucwangcisiweyo lokukhusela umlilo oluzisa iingenelo zexesha elide kunye noxolo lwengqondo. Olu luphuculo olungapheleli nje ekuphuculeni ukuqina kwesakhiwo kodwa luhambelana nokuzibophelela kukhuseleko.
Ekufuneni ukhuseleko oluphuculweyo lomlilo, ukusebenzisa amandla ee-microbeads kwiingubo ezingaphakathi kwesisu linyathelo elihle ekwakheni indawo ekhuselekileyo. Njengoko imfuno yezisombululo zokhuseleko lomlilo eziphucukileyo iqhubeka ikhula, kubalulekile ukuqaphela indima ebalulekileyo edlalwa zii-hollow microspheres ekuphakamiseni imigangatho yokhuseleko kunye nokuqinisa izakhiwo ezichasene nezingozi zomlilo.
Funda indlela ii-microspheres inokuphucula ukhuseleko lomlilo lwesakhiwo kwaye ithathe inyathelo lokuqala lokuqinisekisa ikamva elikhuselekileyo. Yamkela amandla okuvelisa izinto ezintsha kwaye uphakamise imigangatho yokhuseleko lomlilo ngee-cenospheres kwiingubo ezingaphakathi. Masikhuthaze inkcubeko yokhuseleko kunye nokuqina, eqhutywa ngamandla okuguqula izisombululo zokukhusela umlilo eziphambili.
