Ho khutlisa lelakabe ts'ebetsong ea ho tuka ha polymer ea phello e khutlisang lelakabe:
E thibelang lelakabe le lelakabe ho thibela mocheso - phello ea ho monya mocheso
Karolo ea phello ea ho monya mocheso ke ho etsa hore mocheso oa thepa ea polymer o hlahe ka thata.
Ka mohlala, borax e na le limolek'hule tsa 10 tsa metsi a crystalline, e le ho lokolloa ha metsi a crystalline ho hapa 141.8kJ / mol ea mocheso, kahoo ho kenngoa ha mocheso e le hore mocheso oa mocheso oa thepa o thibetsoe, o fella ka phello e thibelang mollo.
Lelakabe le retang lelakabe le retang lelakabe - phello e koahelang
Phello ke ho hlahisa lesela le tsitsitseng la ho koahela ka mocheso o phahameng kapa ho senya ho hlahisa ntho e kang foam e koahelang bokaholimo ba thepa ea polymeric.

E sebetsa e le tšitiso ea moea ho thepa, kahoo e thibela ho phunyeha ha thepa le ho finyella phello e thibelang lelakabe.
Lelakabe le retang malakabe le lelakabe - phello ea dilution
Lintho tsena li ka hlahisa khase e ngata e sa cheng ha e senngoa ke mocheso, e le hore khase e tukang e hlahisoang ke thepa ea polymer le oksijene moeeng e hlapolloe 'me e se ke ea fihla moeling oa mahloriso a tukang.
E thibelang malakabe a lelakabe - phetiso ea phello
Phello ke ho fetola mokhoa oa ho senyeha ha mocheso oa thepa ea polymer, kahoo ho thibela tlhahiso ea likhase tse tukang.
Lelakabe le retang malakabe le lelakabe - phello ea thibelo
Ho ts'oara likarolo tse sebetsang tsa tšebetso ea ho tuka, joalo ka HO- le H-, ho thibela tšebetso ea ketane ea mahala le ho fokotsa sekhahla sa ho tuka ho fihlela lelakabe le tima.
E thibelang lelakabe le lelakabe le retang - phello ea ntlafatso
Lisebelisoa tse ling ha li na phello e thibelang lelakabe ha li sebelisoa li le mong kapa li na le phello e fokolang ea mollo, empa mefuta e fapaneng ea lisebelisoa e ka sebelisoa ho ntlafatsa phello e thibelang lelakabe, joalo ka antimony trioxide le metsoako ea halogen e sebelisoang hammoho.
Mokhoa o thibelang malakabe ts'ebetsong ea ho chesa polymer:
Mochini o thibelang malakabe - mokhoa oa khase ea khase e thibelang lelakabe
Sistimi ea "Vapor phase retardant" e bua ka phello e khutlisang lelakabe ea ho sitisa kapa ho chechisa karabelo ea ho tuka ha ketane mohatong oa khase. Ho lieha ha lelakabe la mouoane haholo-holo ho kenyelletsa:
- Li-radical inhibitors tsa mahala li hlahisoa ha thepa e thibelang lelakabe e futhumatsoa kapa e chesoa, kahoo e sitisa karabelo ea ketane ea ho tuka.
- Tlhahiso ea likaroloana tse ntle ha thepa e thibelang lelakabe e futhumatsoa kapa e chesoa, e khothalletsang ho tlama ha li-radicals tsa mahala ho felisa karabelo ea ho chesa ketane.
- Ho lokolloa ha khase e ngata ea inert kapa mouoane o matla haholo ha thepa e thibelang lelakabe e futhumatsoa kapa e chesoa.
Mekhoa e thibelang lelakabe - mekhoa e khutsitseng ea mohato oa ho thibela lelakabe
Condensed phase retardancy retardancy e bua ka phello e thibelang lelakabe e hlahisoang ke ho lieha kapa ho sitisa ho bola ha mocheso oa lisebelisoa tse thibelang lelakabe mokhahlelong o khutsitseng. Condensed phase flame retadancy haholo-holo e na le:
- Li-retardants tsa malakabe tse thibelang kapa tse sitisang ho bola ha likhase tse tukang le li-radicals tse ka hlahisoang nakong ea ts'ebetso ea coalescence.
- Li-inorganic fillers tse nang le matla a maholo a mocheso ka har'a lisebelisoa tse thibelang lelakabe, tse etsang hore thepa e se be monyetla oa ho fihla mocheso oa ho bola ka ho boloka mocheso le ho tsamaisa mocheso.
- Ho senyeha ha mocheso oa lelakabe la lelakabe ho monya mocheso, e le hore ho phahama ha mocheso oa thepa e thibelang lelakabe ho fokotsehe kapa ho emisoe.
- Ha thepa e thibelang lelakabe e chesa, e hlahisa lesela le nang le porous carbon holim'a eona, eo ho leng thata ho e chesa, e thibela mocheso le oksijene, 'me e thibela khase e tukang ho kena karolong ea khase.
Mochine o thibelang malakabe - tšitiso ea mochine o thibelang mocheso oa mocheso
The sitisoa mocheso phapanyetsano lelakabe retardant mochine bolela hore karolo ea mocheso hlahisoang ke combustion ea lelakabe retardant lintho tse bonahalang e tlosoa, e le hore thepa e ke ke ea boloka mocheso oa ho bola ha mocheso 'me ka hona o sitoa ho boloka tlhahiso ea likhase tse tukang,' me kahoo ho chesa hoa tima.
