Umahluko phakathi kwentambo ethintela ilangatye, intambo engenalo i-halogen kunye nentambo ekhusela umlilo:
Intambo ethintela umlilo ibonakala ngokulibazisa ukusasazeka kwelangabi ecaleni kwentambo ukuze umlilo ungandi. Nokuba yintambo enye okanye inqwaba yeemeko zokubeka, intambo inokulawula ukusasazeka kwelangabi ngaphakathi koluhlu oluthile xa itsha, ukuze iphephe iintlekele ezinkulu ezibangelwa kukusasazeka komlilo. Ngaloo ndlela iphucula inqanaba lokuthintela umlilo kumgca wentambo. Izinto ezisetyenziswa rhoqo ekuthinteleni umlilo ziquka iteyiphu ethintela umlilo,intambo yokuzalisa ethintela ilangatyekunye nezinto zePVC okanye zePE eziqulethe izongezo ezithintela ilangatye.
Iimpawu zentambo ethintela umlilo enomsi omncinci engenamsi we-halogen azipheleli nje ekubeni inamandla okuthintela umlilo, kodwa ikwanokuba izinto ezenza intambo ethintela umlilo enomsi omncinci azinawo umsi we-halogen, ukugqwala kunye nobuthi bomlilo buphantsi, kwaye umsi wenziwa ngomlinganiselo omncinci kakhulu, ngaloo ndlela kunciphisa umonakalo kumntu, kwizixhobo nakwizixhobo, kwaye kwenza kube lula ukuhlangulwa ngexesha elifanelekileyo xa kutsha. Izinto ezisetyenziswa rhoqo ziizinto ezingenayo i-halogen (LSZH) ezinomsi ophantsikunye neteyipu ethintela ilangatye engenalo i-halogen.
Iintambo ezimelana nomlilo zinokugcina ukusebenza okuqhelekileyo kangangexesha elithile kwimeko yokutsha komlilo ukuqinisekisa ukuthembeka komgca. Ubungakanani begesi eneasidi kunye nomsi oveliswa ngexesha lokutsha komgca othintela umlilo buncinci, kwaye ukusebenza komgca othintela umlilo kuphucuke kakhulu. Ingakumbi kwimeko yokutsha okuhamba kunye nokutshizwa ngamanzi kunye nefuthe loomatshini, intambo isenokugcina ukusebenza okupheleleyo komgca. Iintambo ezithintela umlilo ikakhulu zisebenzisa izixhobo ezithintela ubushushu obuphezulu ezifana ne-phlogopa tape kunyeiteyiphu ye-mica eyenziweyo.
1. Yintoni intambo ethintela ilangatye?
Intambo ethintela ilangatye ibhekisa koku: phantsi kweemeko ezithile zovavanyo, isampuli iyatshiswa, emva kokususa umthombo womlilo wovavanyo, ukusasazeka kwelilangatye kungaphakathi koluhlu olulinganiselweyo, kwaye ilangatye eliseleyo okanye ukutsha okushiyekileyo intambo inokuzicima ngokwayo kwixesha elilinganiselweyo.
Iimpawu zayo ezisisiseko zezi: xa kukho umlilo, inokutsha kwaye ayikwazi ukusebenza, kodwa inokuthintela ukusasazeka komlilo. Ngokwesiqhelo, xa intambo itsha, inokukhawulela ukutsha kwindawo ethile, ingasasazeki, ikhusele ezinye izixhobo, kwaye iphephe ukubangela ilahleko ezinkulu.
2. Iimpawu zesakhiwo sentambo ethintela ilangatye.
Ulwakhiwo lwentambo ethintela umlilo ngokusisiseko lufana nolwentambo eqhelekileyo, umahluko kukuba umaleko wayo wokukhusela, isheya, isheya yangaphandle kunye nezinto ezincedisayo (ezifana neteyiphu nezinto zokuzalisa) zenziwe ngokupheleleyo okanye ngokuyinxenye ngezinto ezithintela umlilo.
Izinto ezisetyenziswa rhoqo ziquka i-PVC ethintela ilangatye (kwiimeko ezithintela ilangatye ngokubanzi), iteyiphu ethintela ilangatye engena-halogen okanye engena-halogen (kwiindawo ezineemfuno eziphezulu zokusingqongileyo), kunye nezixhobo zerabha ze-silicone zerabha ze-ceramic ezisebenza kakuhle (kwiimeko ezikumgangatho ophezulu ezifuna zombini ukumelana nomlilo kunye nokumelana nomlilo). Ukongeza, inceda ukujikeleza isakhiwo sekhebula kwaye ithintele ukusasazeka komlilo kwizithuba, ngaloo ndlela iphucula ukusebenza kokuthintela ilangatye ngokubanzi.
3. Yintoni intambo engatshiyo?
Intambo engatshiyo ibhekisa koku: phantsi kweemeko zovavanyo ezithile, isampuli iyatshiswa elangatyeni, kwaye ikani isaqhubeka nokusebenza okuqhelekileyo kangangexesha elithile.
Uphawu lwayo oluphambili kukuba intambo isenokugcina ukusebenza okuqhelekileyo komgca ixesha elithile phantsi kwemeko yokutsha. Ngokubanzi, xa kutsha, intambo ayizukutsha ngaxeshanye, kwaye isekethe ikhuselekile.
4. Iimpawu zesakhiwo sentambo enganyangekiyo.
Ulwakhiwo lwentambo engatshiyo ngokusisiseko lufana nolwentambo eqhelekileyo, umahluko kukuba umqhubi usebenzisa umqhubi wobhedu onokumelana kakuhle nomlilo (indawo yokunyibilika kobhedu yi-1083℃), kwaye umaleko ongatshiyo wongezwa phakathi komqhubi kunye nomaleko wokugquma.
Umaleko ochaseneyo udla ngokusongelwa ngeeleya ezininzi ze-phhlogopite okanye iteyiphu ye-mica eyenziweyo. Ukumelana nobushushu obuphezulu kweebhanti ezahlukeneyo ze-mica kwahluka kakhulu, ngoko ke ukukhethwa kweebhanti ze-mica yeyona nto iphambili echaphazela ukumelana nomlilo.
Umahluko ophambili phakathi kwentambo engatshiyo kunye nentambo ethintela umlilo:
Iintambo ezimelana nomlilo zinokugcina umbane oqhelekileyo ixesha elithile xa kutsha, ngelixa iintambo ezithintela umlilo zingenalo olu phawu.
Ngenxa yokuba iintambo ezingatshiyo zinokugcina ukusebenza kweesekethe ezibalulekileyo ngexesha lomlilo, zidlala indima ebaluleke kakhulu kwizakhiwo zanamhlanje zasezidolophini nakwimizi-mveliso. Zihlala zisetyenziswa kwiisekethe zombane ezidibanisa imithombo yamandla engxamisekileyo nezixhobo zokukhusela umlilo, iinkqubo ze-alamu yomlilo, izixhobo zomoya kunye nezixhobo zokukhupha umsi, izibane ezikhokelayo, amasokhethi ombane engxamisekileyo, kunye neelifti zengxamiseko.
