Ungawaxazulula kanjani amaphuzu obuhlungu okucubungula wezinto zekhebula ezingenantuthu ephansi ye-halogen?

I-LSZH imele intuthu ephansi enguziro halogens, i-halogen engenantuthu ephansi, lolu hlobo lwekhebula nocingo lukhipha intuthu ephansi kakhulu futhi alukhiphi ama-halogen anobuthi lapho luchayeke ekushiseni. Kodwa-ke, Ukuze kuzuzwe lezi zici ezimbili ezibalulekile, ekukhiqizeni izinto zekhebula ezingenantuthu ephansi ye-halogen, ama-halogens ayi-Low-smoke zero halogens (LSZH) alayishwa kakhulu, okuholela ngqo kumishini nokucubungula izakhiwo.

Ubunzima bokucutshungulwa kwezinto ezingenayo intuthu ephansi ye-halogen:

1. Ifomula evamile, i-LLDPE/EVA/ATH okuqukethwe okuphezulu okugcwele i-LSZH polyolefin cable compounds iqukethe kufika ku-55-70% ATH/MDH, Njengenani elikhulu le-aluminium hydroxide, i-magnesium hydroxide, nezinye izinto ezibuyisela amalangabi ukujoyina ukusetshenziswa kokuhamba kwesistimu kubi, ukukhiqizwa kokushisa kwe-frictional ngesikhathi sokucubungula kubangela ukuwohloka kwe-ahydroxide ye-magnesium.

2. Ukusebenza kahle kwe-extrusion okuphansi, noma unyusa isivinini sevolumu ye-extrusion ihlala ifana ngokuyisisekelo.

3. Ukungahambisani kahle kwama-inorganic flame retardants nama-filler ane-polyolefin, ukuhlakazeka okungalungile ngesikhathi sokucubungula, okuholela ekwehleni kwezakhiwo zemishini.

4. Ingaphezulu elimahhadlahhadla kanye nokuntuleka kokucwebezela ngesikhathi sokukhishwa ngenxa yokuhlakazeka okungalingani kwama-inorganic flame retardants ohlelweni.

5.I-polarity yesakhiwo ye-flame retardants kanye nezigcwalisi ibangela ukuncibilika ukuthi kubambelele ekhanda lesikhunta, kubambezele ukukhululwa kwempahla esikhunjeni, noma ama-molecule amancane ekubunjweni avele aphume, okuholela ekwakhekeni kwezinto ezibonakalayo ekuvulekeni kwesikhunta, ngaleyo ndlela kuthinte ikhwalithi yekhebula.

Ngokusekelwe ezindabeni ezingenhla, i-SILIKE yenze uchungechunge lweisithako se-siliconeimikhiqizo eklanyelwe ngokukhethekile ukubhekana nezindawo ezibuhlungu zokucutshungulwa kanye nekhwalithi yangaphezulu yezinto zekhebula ezingenantuthu ephansi ye-halogen, izinhlanganisela zezintambo ze-halogen ze-halogens ezinentuthu ephansi, noma ezinye izinhlanganisela zePolyolefin ezigcwele amaminerali amaningi zokufakwa kwezintambo nezintambo, ezinikeza izixazululo ezihlukahlukene ezisebenzayo kulezi zinselele.

Isb:I-Silicone Masterbatch (Siloxane Masterbatch) LYSI-401iwukwakheka kwe-pelletized ene-50% ye-ultra-high molecular weight siloxane polymer ehlakazwe ku-low-density polyethylene (LDPE). Isetshenziswa kabanzi njengesengezo sokucubungula esisebenzayo ezinhlelweni ze-resin ezihambisana ne-PE ukuze kuthuthukiswe izakhiwo zokucubungula nokuguqula ikhwalithi ephezulu.

Ukungeza u-0.5-2% weSILIKE abicah masterbatch LYSI-401ohlelweni lokugcwalisa olubushelelezi ilangabi oluphansi lwentambo yamahhala ye-halogen & ikhebula eliphansi noma izinto zekhebula eziphansi ze-zero (LSZH) zenza izintambo kanye nabenzi bezintambo bakhulise ukukhiqiza, bangathuthukisa uketshezi lokucubungula, banciphise i-torque, isivinini somugqa we-extrusion osheshayo ngaphandle kokufuduka, ukuthuthukisa ikhwalithi yangaphezulu yentambo ephansi kanye nentambo ephansi, kanye nokungasebenzi kahle, ukumelana, ukushelela okungcono, kanye nomuzwa wesandla ...) ngaphandle kokukhokha iprimiyamu yezithasiselo zokusebenza ezingadingekile.

Ngokuvamile, okwejwayelekilei-silicone masterbatch, i-siloxane ayiyona i-polar, futhi iningi lepharamitha ye-carbon chain polymer solubility yomehluko mikhulu kakhulu, ukungezwa kwenani elikhulu lamacala kungaholela ekucutshungulweni kwe-screw slippage, ukugcotshwa ngokweqile, ingaphezulu lomkhiqizo we-delamination, okuthinta ingaphezulu lemikhiqizo yezakhiwo zokubopha zemikhiqizo ku-substrate ehlakazekile ngokungalingani nokunye.

Ngenkathi,Izithasiselo ze-silicone ze-molecular high-high molecular weightzilungiswa ngamaqembu akhethekile, angakhethwa futhi afaniswe ngokuvumelana nezidingo ezahlukene zezithasiselo ze-silicone kuma-substrates ahlukene. Lolu chungechunge lwemikhiqizo lungadlala indima yokubambelela ku-substrate, ngaleyo ndlela ihambisane kangcono ne-substrate, ukusabalalisa okulula, ukubopha okuqinile, futhi ngaleyo ndlela kunikeze i-substrate ukusebenza okuhle kakhulu. Uma isetshenziswa ezinhlelweni ze-LZSH ne-HFFR, ingagwema ngempumelelo ukushelela kwesikulufa futhi ingadlala indima ebalulekile ekuthuthukiseni ukunqwabelana kwezinto ezisesikhunjini somlomo.
