Phetoho ea Lisebelisoa tsa Cable e se nang Mollo oa Halogen

Ka tsoelo-pele ea theknoloji, ho na le tlhoko e ntseng e eketseha ea polokeho le ts'epo libakeng tse koetsoeng le tse nang le baahi ba bangata joalo ka liteishene tsa terene e tsamaeang ka tlas'a lefatše, mehaho e meholo, hammoho le libaka tsa bohlokoa tsa sechaba joalo ka likepe le lifeme tsa matla a nyutlelie. Ka lebaka leo, ho na le tlhoko e potlakileng ea ho nts'etsapele mefuta e mecha ea lithapo tse nang le thepa e fokolang ea mosi, e se nang halogen, le e thibelang malakabe. Mathoasong a bo-1980, linaha tse tsoetseng pele lefatšeng ka bophara li ile tsa qala ho etsa lipatlisiso le ho hlahisa thepa le lithapo tse fokolang tsa halogen tse se nang mosi o tlase. Lithapo tse fokolang tsa halogen tse se nang malakabe li se li amohetsoe ka potlako le ho sebelisoa hohle. Chaena, bahlahisi ba terata le lithapo metseng e kang Shanghai, Shenyang, Suzhou, Sichuan, Xiangtan, le Wuxi ba hlahisitse lithapo tsa motlakase tse thibelang malakabe ka tatellano, lithapo tse tenyetsehang tsa rabara tse shebiloeng ka rabara, lithapo tsa likepe tse thibelang malakabe, le lihlahisoa tse ling tse amanang le tsona.

Li-modifiers li sebelisoa ka har'a lisebelisoa tsa cable tse kopantsoeng tse se nang malakabe tse se nang halogen, tse kang aluminium hydroxide le magnesium hydroxide, ho ntlafatsa ho lumellana le ho khomarela pakeng tsa polyolefin matrix le li-inorganic flame retardants. Li ntlafatsa ho hasana le ho lumellana ha aluminium hydroxide le magnesium hydroxide, ka hona li eketsa ho lieha ha malakabe ha thepa ea cable, li fokotsa index ea mosi, ho tsoa ha mosi, ho lokolloa ha mocheso le tlhahiso ea carbon monoxide, li eketsa index ea oksijene, 'me li ntlafatsa ho hanyetsa ha marotholi. Li-modifiers tsena li ntlafatsa haholo thepa ea mechine le ea mocheso ea thepa. Ho eketsa karolo e nyane ho ka ntlafatsa ts'ebetso ea mechini ea thepa e kopantsoeng, ho eketsa matla a ho tsitlella le ho lelefala, hammoho le ho hanyetsa mocheso le ho lieha ha malakabe.

Likopo tse Tloaelehileng:

1. Sesebediswa sa ho Kopanya: Se sebediswa bakeng sa di-halogen-free flame retardants tse kang aluminium hydroxide le magnesium hydroxide ho ntlafatsa ho tsamaellana le ho kgomarelana pakeng tsa polyolefin matrix le inorganic flame retardants. Ho eketsa 8%–10% ho ka ntlafatsa haholo thepa ya mechini le ho hanyetsa mocheso wa thepa e kopaneng. Ha ho bapiswa le di-coupling agent tse tlwaelehileng tse kang silane, titanate, aluminate, le phosphate esters, e fana ka ntlafatso e betere thepa ya mechini ya thepa ya cable ya polyolefin.
2. Mohlohlelletsi oa ho Hasanya: E sebelisoa ho polyolefin masterbatches, masterbatches e thibelang malakabe, le masterbatches e senyehang. Ka lebaka la tšebelisano ea eona e matla le li-pigment, lidae, le li-retant tsa malakabe, e khothalletsa ho hasana ha li-additives tsena ka har'a resin ea polyolefin carrier.
3. Mohlohlelletsi oa Bonding: E ​​na le polarity e phahameng le reactivity. Ho eketsa hanyane ho ka ntlafatsa haholo ho penta, ho khomarela le ho lumellana ha thepa.
