Joang ho rarolla lintlha tse bohloko tsa ho sebetsana le lisebelisoa tsa cable tse se nang mosi oa halogen?

LSZH e emetse li-halogens tsa mosi o tlase, tse sa tsubeng haholo halogen, mofuta ona oa thapo le terata li ntša mosi o fokolang haholo 'me ha li ntše li-halogen tse chefo ha li le mocheso. Leha ho le joalo, E le hore u finyelle lintlha tsena tse peli tsa bohlokoa, tlhahiso ea lisebelisoa tsa cable tse se nang mosi o tlaase oa halogen, li-halogens tse tlaase tsa mosi (LSZH) li imetsoe haholo, tse lebisang ka ho toba ho thepa ea mechine le ea ho sebetsa.

Mathata a ho sebetsa ha thepa e se nang mosi o tlase oa halogen:

1. Foromo e tloaelehileng, LLDPE / EVA / ATH e phahameng e tletseng LSZH polyolefin cable compounds e na le ho fihlela ho 55-70% ATH / MDH, Kaha palo e kholo ea aluminium hydroxide, magnesium hydroxide, le li-flame retardants tse ling ho ikopanya le tšebeliso ea tsamaiso ea tsamaiso e futsanehile, moloko oa mocheso oa frictional nakong ea ts'ebetso o lebisa ho eketseha ha mocheso oa hydroxide.

2. Katleho e tlase ea extrusion, le haeba o eketsa lebelo la molumo oa extrusion e ntse e tšoana.

3. Tšebelisano e mpe ea li-inorganic flame retardants le li-filler tse nang le polyolefin, ho hasana ho fokolang nakong ea ts'ebetso, ho fella ka ho fokotseha ha thepa ea mochine.

4. Sebaka se thata le ho haella ha gloss nakong ea extrusion ka lebaka la ho hasana ho sa tšoaneng ha li-inorganic flame retardants tsamaisong.

5.Polarity ea sebopeho sa li-retardants tsa lelakabe le li-fillers li etsa hore ho qhibiliha ho khomarele hlooho ea hlobo, ho liehisa ho lokolloa ha thepa ho tloha hlobo, kapa limolek'hule tse nyenyane tse entsoeng li tsoa, ​​​​ho fella ka ho bokellana ha thepa ha ho buloa hlobo, kahoo ho ama boleng ba mohala.

Ho latela lintlha tse ka holimo, SILIKE e hlahisitse letoto lamotsoako oa siliconelihlahisoa tse etselitsoeng ka ho khetheha ho sebetsana le lintlha tse bohloko tsa ho sebetsa le boleng ba holim'a lisebelisoa tsa cable tse se nang mosi oa halogen, mosi o tlase oa zero halogens wire&cable compounds, kapa metsoako e meng ea Polyolefin e tletseng liminerale haholo bakeng sa lisebelisoa tsa terata le lithapo, tse fanang ka mefuta e fapaneng ea litharollo tse sebetsang liphephetsong tsena.

Mohlala:Silicone Masterbatch (Siloxane Masterbatch) LYSI-401ke sebopeho sa pelletized se nang le 50% ultra-high molecular weight siloxane polymer e qhalakantsoeng ka polyethylene e tlaase-tlaase (LDPE). E sebelisoa haholo joalo ka tlatsetso e sebetsang hantle lits'ebetsong tsa resin tse lumellanang le PE ho ntlafatsa thepa ea ts'ebetso le ho fetola boleng ba bokaholimo.

Ho eketsa 0.5-2% eaSILIKE silicone masterbatch LYSI-401Sistimi ea ho tlatsa lelakabe le lengata la mosi o tlase oa mohala o sa lefelloeng oa halogen kapa lisebelisoa tsa thapo tsa mosi o tlase oa zero (LSZH) o thusa baetsi ba terata le lithapo ho eketsa tlhahiso, ba ka ntlafatsa phallo ea metsi, ba fokotsa torque, lebelo le potlakileng la ho phatloha holim'a metsi ntle le phallo efe kapa efe, ho ntlafatsa boleng ba terata le thapo e tlase, le thapo e tlase, le thapo e tlase, le ho sebetsa hantle. ho hanyetsa, ho thella ho betere, le maikutlo a letsoho ...) ntle le ho lefa tefo bakeng sa lisebelisoa tse sa hlokahaleng tsa ts'ebetso.

Hangata, bakeng sa Tloaelehilengsilicone masterbatch, siloxane ha e polar, 'me boholo ba liparamente tsa carbon chain polymer solubility tsa phapang li kholo haholo, ho eketsoa ha palo e kholo ea linyeoe ho ka lebisa ts'ebetsong ea screw slippage, lubrication e feteletseng, bokaholimo ba sehlahisoa sa delamination, se amang bokaholimo ba lihlahisoa tsa lihlahisoa tsa lihlahisoa tse ka har'a substrate tse hasantsoeng ka mokhoa o sa tšoaneng joalo-joalo.

Leha ho le joalo,SILIKE's ultra-high molecular weight silicone additivesli fetotsoe ke lihlopha tse khethehileng, tse ka khethoang le ho bapisoa ho ea ka litlhoko tse fapaneng tsa li-additives tsa silicone ka li-substrates tse fapaneng. Letoto lena la lihlahisoa le ka bapala karolo ea ho tiisa ka har'a substrate, ka hona, ho tsamaellana hamolemo le substrate, ho hasana habonolo, ho tlamahanngoa ho matla, 'me ka hona ho fa substrate ts'ebetso e ntle haholo. Ha e sebelisoa litsamaisong tsa LZSH le HFFR, e ka qoba ho thella ha screw mme e ka bapala karolo ea bohlokoa ho ntlafatseng pokello ea lintho tse ka har'a hlobo ea molomo.
