Intshayelelo:
Iiplastiki zisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yokuguquguquka kwazo kunye nokusebenza kakuhle kweendleko.Nangona kunjalo, ukutsha kwabo kubangela iingozi ezinokuthi zibekho, okwenza ukuba idangatye libe yindawo ebalulekileyo yophando.Olu phononongo lovavanyo lujolise ekuphandeni ukusebenza kwezixhobo ezahlukeneyo zokubuyiswa komlilo ekwandiseni ukumelana nomlilo kweeplastiki.
Indlela yokusebenza:
Kule sifundo, sikhethe iintlobo ezintathu ezisetyenziswa ngokuqhelekileyo iiplastiki: i-polyethylene (PE), i-polypropylene (PP), kunye ne-polyvinyl chloride (PVC).Uhlobo ngalunye lweplastiki luphathwe ngeento ezintathu ezahlukeneyo zokunqanda umlilo, kwaye iimpawu zabo ezikwazi ukumelana nomlilo zithelekiswe neesampuli ezinganyangwanga.Iiretardants zomlilo ezibandakanyiweyo yayiyi-ammonium polyphosphate (APP), i-aluminium hydroxide (ATH), kunye ne-melamine cyanrate (MC).
Inkqubo yoMfuniselo:
1. ULungiselelo lweSampuli: Iisampulu zodidi ngalunye lweplastiki zilungiswe ngokwemilinganiselo eqhelekileyo.
2. Unyango lwe-Flame Retardant: Izithinteli zomlilo ezikhethiweyo (i-APP, i-ATH, kunye ne-MC) zixutywe kunye nodidi ngalunye lweplastiki lulandela umlinganiselo ocetyiswayo.
3. Uvavanyo loMlilo: Iisampulu zeplastiki eziphathwayo nezingaphathwanga ziphantsi kolawulo lomlilo olawulwayo kusetyenziswa isitshisi seBunsen.Ixesha lokutshisa, ukusasazeka kwedangatye, kunye nesizukulwana somsi sajongwa kwaye sarekhodwa.
4. Ukuqokelelwa kwedatha: Imilinganiselo ibandakanya ixesha lokutshisa, izinga lokusasazwa komlilo, kunye novavanyo olubonakalayo lokuveliswa komsi.
Iziphumo:
Iziphumo zokuqala zibonisa ukuba zontathu iiretardants zomlilo ziphucule ngempumelelo ukuxhathisa umlilo kwiiplastiki.Iisampulu eziphathwayo zibonise amaxesha amade okutshisa kunye nokusasazeka kancinci kwedangatye xa kuthelekiswa neesampulu ezingaphathwanga.Phakathi kwabasemva, i-APP ibonise ukusebenza kakuhle kwe-PE kunye ne-PVC, ngelixa i-ATH ibonise iziphumo eziphawulekayo zePP.Ukuveliswa komsi omncinci kubonwe kwiisampulu ezinyangwe kuzo zonke iiplastiki.
Ingxoxo:
Uphuculo oluphawulweyo lokuchasa umlilo lucebisa ukuba ngaba zithinteli zedangatye ukomeleza ukhuseleko lwemathiriyeli yeplastiki.Umahluko ekusebenzeni phakathi kweentlobo zeplastiki kunye ne-flame retardants kunokubalelwa kwiiyantlukwano ekubunjweni kweekhemikhali kunye nesakhiwo sezinto eziphathekayo.Uhlalutyo olongezelelweyo luyafuneka ukuqonda iindlela ezisisiseko ezinoxanduva lweziphumo eziqatshelweyo.
Isiphelo:
Olu phononongo lovavanyo lugxininisa ukubaluleka kokubuyiswa komlilo kwiiplastiki kwaye lugxininisa iziphumo ezilungileyo ze-ammonium polyphosphate, i-aluminium hydroxide, kunye ne-melamine cyanrate njengezinto ezisebenzayo zokunqanda ilangatye.Iziphumo ezifunyenweyo zinegalelo ekuphuhlisweni kwezixhobo zeplastiki ezikhuselekileyo zosetyenziso olwahlukeneyo, ukusuka kulwakhiwo ukuya kwimpahla yabathengi.
Uphando olongezelelweyo:
Uphando lwexesha elizayo lunokuphonononga ukulungelelaniswa komlinganiselo wokubuyiswa komlilo, uzinzo lwexesha elide lweeplastiki ezinyangwayo, kunye nefuthe lokusingqongileyo kwezi zithinteli zomlilo.
Ngokuqhuba olu phononongo, sijonge ukubonelela ngeembono ezixabisekileyo ekuqhubeleni phambili kweeplastikhi ezingenamlilo, ukukhuthaza izinto ezikhuselekileyo kunye nokunciphisa iingozi ezinxulumene nokutsha kweplastiki.
