Ngaba i-intumescent encinci yokuthintela umlilo okanye ayinayo intumescent

I-intumescent yokugquma umlilo

Inokwahlulwa ibe ngamacandelo amabini asekelwe kwi-solvent-based kunye namanzi, iindidi ezimbini zeengubo ezikhethiweyo ngamacandelo omlilo zifana ngokufanayo, ngoko kunzima ukuthetha ukuba ungakanani umehluko ekusebenzeni komlilo, i-solvent ekhethiweyo ukusebenzisa ifilimu. -ukwenza izinto. I-solvent-based based fireproof covering film-forming substances zikhethwa ngokubanzi irabha eneklorini, phezu kwe-lv vinyl, i-amino resins, i-phenolic resins, njl., Ukusetyenziswa kwe-solvents kwi-spray yepeyinti kunye nokunye. Izinto zokugquma iifilim ezisekelwe emanzini.

I-non-intumescent yokugquma umlilo

I-coating ayifuni ukutshintsha umthamo xa iphantsi komlilo. Ngokukodwa, i-coating ngokwayo ayinakutsha okanye ayinakutsha, enokuthi ithintele ilangatye ukuba lisasazeke, kwaye i-coating inokubola iigesi ezingenakutsha phantsi kwesenzo sokushisa okuphezulu okanye ilangatye lokunciphisa ukuxinwa kwe-oksijeni kunye neegesi ezinokutsha emoyeni, ukuze kuthintelwe okanye kubambezeleke ukutsha. Ukongeza, ukugquma kumaqondo obushushu aphezulu okanye phantsi kwentshukumo yedangatye kunokwenza umaleko okhuselayo ongatshiyo ogquma umphezulu wesubstrate enokutsha kunye nokunxibelelana kweoksijini, ukuze uphephe okanye ukunciphisa ukwenzeka kwe-reaction yokutsha, kwaye ngexesha elithile kunye neqondo elithile le-thermal insulation.

Ngokwendlela yokuthintela umlilo, yahlulwe ibe yintsimbi ye-intumescent kunye ne-non-intumescent yesakhiwo sensimbi yomlilo; isakhiwo intsimbi non-intumescent ukutyabeka umlilo libhekisela kwisakhiwo intsimbi ukutyabeka umlilo ukuba ukutyabeka musa ukwandisa kwaye amagwebu kwiqondo lobushushu eliphezulu, kwaye ibe umaleko ukumelana nomlilo kunye nobushushu-insulating yokhuselo ngokwayo.

Ngokutsho umgangatho yamva nje kazwelonke GB14907-2018, amanzi-based/solvent-based non-intumescent eqhelekileyo/isakhiwo intsimbi ekhethekileyo ukutyabeka umlilo. Ubungqingqwa bokugquma kwesakhiwo sentsimbi esingeyo-intumescent yokwaleka umlilo abuyi kuba ngaphantsi kwe-15㎜.

Isakhiwo sensimbi esingeyosi-intumescent i-fireproof coating i-fire insulation principle kukuba i-coating ayifuni ukutshintsha umthamo xa iphantsi komlilo, kodwa i-thermal conductivity ye-coating iphantsi kakhulu, ebambezela isantya sokudluliselwa kobushushu kwi-insured substrate. kunye nokugquma kwengubo yomlilo ngokwayo ayinakutsha, kwaye isebenza njengesithintelo kwaye ithintele ukushisa kwemitha yamacandelo ensimbi, okuthintela ilangatye kunye nokushisa okuphezulu ekuhlaseleni ngokuthe ngqo amacandelo ensimbi.  

Kukho amacandelo athile kwi-coating asabelana ngayo xa umlilo uvelisa umzimba ongeyogesi yinkqubo yokusabela kokufunxa ubushushu, kodwa ikwasebenzisa ubushushu obuninzi, obunceda ukuthoba ubushushu benkqubo, umphumo wokukhusela umlilo uyamangalisa, kwaye udlala ukhuseleko lomlilo olusebenzayo kunye nokukhusela i-thermal insulation yensimbi. Ukongeza, olu hlobo lwesakhiwo sentsimbi yokugquma umlilo siphantsi komlilo xa utshintsho lutshintsha ukwenza umaleko okhuselayo okhazimlayo, onokudlala indima ekuhlukaniseni ioksijini, ukuze ioksijini ingakhuselwa yinto enokutsha.
