Halogen-Free Flame Retardant Material Modifier

Halogen-Free Flame Retardant Material Modifier

Ka tsoelopele ea theknoloji, ho na le tlhokahalo e ntseng e eketseha ea polokeho le ts'epahalo libakeng tse koaletsoeng le tse nang le baahi ba bangata joalo ka liteishene tsa metro, meaho e mekato e phahameng, hammoho le lits'ebeletso tsa bohlokoa tsa sechaba joalo ka likepe le lifeme tsa matla a nyutlelie. Ka lebaka leo, ho na le tlhokahalo e potlakileng ea ho hlahisa mefuta e mecha ea lithapo tse nang le thepa e sa hleng haholo, e se nang halogen le e thibelang malakabe. Mathoasong a lilemo tsa bo-1980, linaha tse tsoetseng pele lefatšeng ka bophara li ile tsa qala ho etsa lipatlisiso le ho hlahisa thepa le mehala e thibelang malakabe e sa chesehang halogen. Lithapo tse thibelang malakabe tse se nang Halogen esale li bona ho amoheloa ka potlako le tšebeliso e atileng. Chaena, baetsi ba lithapo le lithapo metseng e kang Shanghai, Shenyang, Suzhou, Sichuan, Xiangtan, le Wuxi ba thehile ka ho latellana lithapo tsa motlakase tse thibelang malakabe, meepo e thibelang malakabe e koetsoeng ka rabara, lithapo tsa likepe tse sa cheseheng le lihlahisoa tse ling tse amanang le tsona.

Li-modifiers li sebelisoa ka har'a lisebelisoa tsa lithapo tse tlatsitsoeng tsa li-halogen tse se nang lelakabe tse tlatsitsoeng ke mollo, joalo ka aluminium hydroxide le magnesium hydroxide, ho ntlafatsa tšebelisano le ho khomarela lipakeng tsa polyolefin matrix le li-inorganic flame retardants. Li ntlafatsa ho hasana le ho tsamaellana ha aluminium hydroxide le magnesium hydroxide, ka tsela eo li eketsa ho lieha ha lelakabe la lisebelisoa tsa cable, ho fokotsa index ea mosi, ho tsoa mosi, ho lokolloa ha mocheso le tlhahiso ea carbon monoxide, ho eketsa index ea oksijene le ho ntlafatsa ho hanyetsa marotholi. Li-modifiers tsena li ntlafatsa haholo sebopeho sa mochini le mocheso oa thepa. Ho eketsa chelete e nyane ho ka ntlafatsa ts'ebetso ea mochini oa lisebelisoa tse kopaneng, ho eketsa matla le bolelele, hammoho le ho hanyetsa mocheso le ho lieha ha lelakabe.

Lisebelisoa tse Tloaelehileng:

1. Coupling Agent: E sebelisoa bakeng sa li-retardants tse se nang halogen tse kang aluminium hydroxide le magnesium hydroxide ho ntlafatsa ho lumellana le ho khomarela pakeng tsa polyolefin matrix le inorganic flame retardants. Ho eketsa 8% -10% ho ka ntlafatsa le ho feta thepa ea mochini le ho hanyetsa mocheso oa thepa e kopantsoeng. Ha ho bapisoa le lisebelisoa tse tloaelehileng tse kopanyang tse kang silane, titanate, aluminate, le phosphate esters, e fana ka ntlafatso e betere meahong ea mochini oa lisebelisoa tsa cable tsa polyolefin.
2. Dispersing Promoter: E sebelisoa ho polyolefin masterbatches, li-masterbatches tse thibelang mollo, le li-masterbatches tse senyehang. Ka lebaka la tšebelisano e matla le li-pigment, dae le li-flame retardants, e khothalletsa ho hasana ha li-additives tsena ka har'a polyolefin carrier resin.
3. Bonding Promoter: O na le polarity e phahameng le reactivity. Ho eketsa chelete e nyenyane ho ka ntlafatsa haholo ho penta, ho khomarela le ho lumellana ha thepa.
