Xa kuziwa ekukhuselweni komlilo, iingubo ze-intumescent zidlala indima ebalulekileyo ekukhuseleni ukusasazeka komlilo kunye nokukhusela izakhiwo emonakalweni we-thermal. Ezi zambatho zenzelwe ukwandisa xa zibekwe emlilweni kwaye zenze umaleko oshinyeneyo wamalahle, ukubonelela ngomqobo kwi-substrate engaphantsi kunye nokunciphisa ukusasazeka kwamadangatye. Isithako esibalulekileyo esinokuthi siphucule ukusebenza kweengubo zokugqoka ezifakwe kwi-intumescent kukongeza i-cenospheres njengezizalisi.
Ii-cenospheres zikhaphukhaphu, ii-microspheres ze-ceramic ezingenanto ezivunyiweyo ngokukwazi kwabo ukuphucula ukumelana nomlilo kunye neempawu zokugquma kwezixhobo ezahlukeneyo. Xa zisetyenziswa njengezizalisi kwiingubo ze-intumescent, i-cenospheres engenanto inokuzisa utshintsho oluthile kunye nophuculo olunokunceda ngokhuseleko olungcono lomlilo.
Kutheni le nto iimicrospheres ezingenanto zisetyenziswa njengezizalisi kwiingubo zokwaleka?
I-Cenospheres isetyenziswa ngokubanzi kwi-intumescent coating formulations ngenxa yeempawu zabo ezizodwa. Njengama-microspheres angenanto, banokunciphisa ngokufanelekileyo ubuninzi bengubo ngaphandle kokuchaphazela amandla ayo omatshini. Lo mhlaba ukhaphukhaphu ukhokelela ekubeni i-coating yenze umaleko ojiyileyo nofanayo ngakumbi xa ibekwe emlilweni, ngaloo ndlela iphucula ukuxhathisa kwayo emlilweni.
Ukongeza, ii-microspheres ezingenanto zineempawu ezibalaseleyo zokufakelwa kwe-thermal, ezinceda ukunciphisa ukuhanjiswa kobushushu ngexesha lomlilo. Oku kugquma kunceda ukugcina ingqibelelo ye-substrate engaphantsi, ikhusela umonakalo wesakhiwo, kunye nokunciphisa ukusasazeka kwamadangatye. Ukongeza, imilo engqukuva yamaso angenanto ivumela ukupakishwa okungcono kwimatrix yepeyinti, ngaloo ndlela iphucula ukusasazeka kunye nokuzinza.
Utshintsho kunye nokuPhuculwa ekongezeni i-Cenospheres kwiipende ze-Intumescent
Ukongezwa kwee-microspheres ezingenanto njengezizalisi kwiingubo ze-intumescent zisa utshintsho kunye nokuphuculwa okuye kwaphucula ukusebenza komlilo ngokubanzi. Okokuqala, ukongezwa kwee-microspheres ezingenantokunciphisa ukuxinana yepeyinti, iyenza ibe khaphukhaphu kwaye kube lula ukuyifaka. Oku kuququzelela inkqubo yesicelo kunye nokuqinisekisa ukhuseleko olungcono, okubangela umqobo womlilo osebenzayo.
Ukongezelela, iipropati ze-thermal insulation ze-microspheres ezingenanto zincedaukuphucula ukusebenza kwe-thermal yokwaleka intumescent. Umaleko wamalahle owenzeka xa utyhilekile emlilweni uba ngqindilili kwaye umelane nobushushu, unika ukhuseleko olongeziweyo kwi-substrate engaphantsi. Oku kuthetha ukumelana nomlilo ophezulu kunye nexesha elide lokukhusela umlilo, izinto eziphambili ekukhuseleni izakhiwo kunye nezakhiwo.
Ukongeza, ukusetyenziswa kweiicenospheres ezingenanto kwiingubo ze-intumescent zenza ukunamathela okungcono kunye nokudibanisa ngaphakathi kwe-matrix yokwambathisa. Ubume obungqukuva kunye nokusabalalisa ubungakanani bamasuntswana obufanayo be-cenospheres bukhuthaza ngakumbi ukusasazwa ngaphakathi kwengubo, okukhokelela ekuphuculeni uzinzo kunye nomqobo onamandla womlilo. Olu manyano luqiniweyo luqinisekisa ukuba umaleko wamalahle uhlala unjalo kwaye ubonelela ngokhuseleko oluqhubekayo malunga nokusasazeka kwamadangatye.
Ukusebenzisa i-cenospheres kwiingubo ze-intumescent ukunyusa ukhuseleko lomlilo
Isishwankathelo, ukusetyenziswa kwee-microspheres ezingenanto njengezizaliso kwiingubo ze-intumescent zibonelela ngeenzuzo ezininzi kwaye zinokuphucula kakhulu iipropati zokukhusela umlilo. Ngokusebenzisa iipropathi ezikhethekileyo ze-microspheres ezingenanto, ezifana nokukhanya kwazo, ukukwazi ukugquma, kunye nokusasazwa okuphuculweyo, ukusebenza kweengubo ze-intumescent kunokongezwa ukubonelela ukumelana nomlilo kunye nokhuseleko oluphezulu.
Xa ujonge ukuphucula ukusebenza komlilo wesakhiwo, indima ebalulekileyoiicenospheres ukudlala ekwandiseni ukusebenza kweengubo zokuhombisa kufuneka kuthathelwe ingqalelo. Ngokubandakanya i-microspheres kule ngqungquthela, umqobo womlilo osebenzayo kunye nothembekileyo unokudalwa, ukunciphisa ukusasazeka kwamadangatye kunye nokunciphisa umngcipheko wokulimala kwesakhiwo.
Njengoko imfuno yezisombululo eziphambili zokukhusela umlilo ziqhubeka zikhula, ukufakwa kwee-microspheres ezingenanto kwiingubo ze-intumescent kunika amathuba amahle kakhulu okuphucula imigangatho yokhuseleko lomlilo kwiintlobo ezahlukeneyo zoshishino kunye nezoshishino. Ngokwamkela le ndlela intsha, amashishini kunye namashishini anokwenza lukhuni izakhiwo zawo ngokuchasene nezisongelo zomlilo kwaye abeke phambili ukhuseleko lwabantu kunye nempahla.
Ukudibanisa i-cenospheres kwi-intumescent coatings yi-intumescent, utyalo-mali olucwangcisiweyo lokukhusela umlilo olunikezela ngeenzuzo zexesha elide kunye noxolo lwengqondo. Oku kukuhambela phambili okunganyusi nje kuphela ukomelela kwesakhiwo kodwa kuhambelana nokuzibophelela kukhuseleko nokhuseleko.
Ekufuneni ukhuseleko lomlilo oluphuculweyo, ukusebenzisa amandla ee-microbeads kwiingubo ze-intumescent linyathelo elilungileyo lokwakha indawo ekhuselekileyo. Njengoko imfuno yezisombululo eziphambili zokhuseleko lomlilo ziqhubeka zikhula, kubalulekile ukuqaphela indima ebalulekileyo eyenziwa yi-microspheres engenanto ekuphakamiseni imigangatho yokukhusela kunye nokuqinisa izakhiwo ezichasene nezisongelo zomlilo.
Fundanjani iimicrospheres inokomeleza ukhuseleko lomlilo wesakhiwo kwaye ithathe inyathelo lokuqala ekuqinisekiseni ikamva elikhuselekileyo. Yamkela amandla okwenza izinto ezintsha kwaye uphakamise imigangatho yokhuseleko lomlilo kunye ne-cenospheres kwiingubo ze-intumescent. Masikhuthaze inkcubeko yokhuseleko kunye nokomelela, eqhutywa ngamandla okuguqula izisombululo zokukhusela umlilo.
