Imbali yeIzongezo zeSilicone / Silicone masterbatch/ Siloxane masterbatchkunye nendlela esebenza ngayoucingo & iikhompawundi cableishishini?

izongezo zeSilicone ngeI-50% esebenzayo ye-silicone polymerisasazwe kwisiphathi njenge-polyolefin okanye iminerali, ngohlobo lwegranular okanye umgubo, isetyenziswa ngokubanzi njengoncedo lokuqhuba kwishishini lentambo kunye nentambo. Iimveliso ezaziwayo ezifanaSILOXANE MB50Uchungechunge lusebenza njenge-lubricant okanye i-rheological modifier kwishishini lentambo kunye nentambo kwaye yaziswa okokuqala ukusuka eDow Corning eUnited States kwiminyaka engamashumi amabini eyadlulayo, emva kokoenye i-SILICONE MASTERBATCH MB50wabonakala emarikeni kunyeI-70% i-polymer ye-silicone esebenzayoisasazwe kwi-carrier njenge-silica, kunye nefom yegranular ngokunjalo, emva koko iimveliso ezivela kwi-Chengdu Silike zavela kwimarike ukususela ngonyaka ka-2004, kunye nomxholo we-silicone ukusuka kwi-30-70% kunye ne-granular okanye ifom ye powder.

Iiparamitha zobugcisa be-silicone masterbatch yorhwebo kufuneka ibandakanye umxholo olandelayo:

(1) Xa usebenza njenge-lubricant okanye i-rheological modifier, umxholo usuka kwi-5 ukuya kwi-50%

2 Ukuba i-inorganic mineral powder isetyenziswa njengomphathi, igama lomgubo kufuneka liboniswe. Ubumhlophe kunye nokucoleka komgubo we-inorganic kubalulekile kubathengi, kwaye umgubo omhlophe kunye ne-micron ubukhulu kufuneka bonyulwe kangangoko ukuveliswa.

Xa usebenza njengezithambiso okanye izilungisi zerheological

Kwizinto zePolyethylene

Njengoko kusaziwa, into "yesikhumba sikakrebe" ihlala isenzeka xa ukhupha i-polyethylene insulated okanye iingcingo ezikhuselweyo kunye neentambo, ngakumbi xa ukhupha i-linear low-density polyethylene (LLDPE) okanye i-ultra-low density polyethylene (ULDPE okanye i-POE). Izixhobo ze-polyethylene ezongeziweyo ezinqamlezileyo (nokuba i-peroxide cross-linking okanye i-silane cross-linking) nayo ngamanye amaxesha ifumana into "yesikhumba sikakrebe", ngenxa yokungaqwalaselwanga ngokwaneleyo kwenkqubo yokuthambisa kwifomula yezinto. Inkqubo yangoku yamazwe ngamazwe kukongeza amanani omkhondo we-fluoropolymers kwifomula, kodwa ixabiso liphezulu kwaye isicelo silinganiselwe.

Ngomlinganiselo omncinci weI-silicone yobunzima bemolekyuli ye-ultra-high(0.1-0.2%) kwi-polyethylene okanye i-polyethylene edibeneyo inokuthintela ngokufanelekileyo ukuveliswa "kwesikhumba se-shark". Kwangaxeshanye, kunye nefuthe layo lokuthambisa, inokunciphisa ngokufanelekileyo i-torque ye-extrusion ukukhusela i-motor yokutsala ukuba ime ngenxa yokugcwala.

I-Silicone esetyenziswe njenge-lubricant, ngenxa yokongezwa kwayo encinci, kufuneka ihanjiswe ngokulinganayo kwizinto eziphathekayo ukuze isebenze ngexesha lokucubungula. Ngenxa ye-inertness yeekhemikhali ye-silicone, ayiyi kusabela ngamachiza kunye namacandelo kwifomula. Kunconywa ukuba i-cable material factory idibanise ngokulinganayo i-silicone kwi-plasticizing granulation process ukuququzelela ukusetyenziswa kwefektri yentambo.

KubaI-Halogen yasimahla ye-flame retardent (HFFR) iikhompawundi zentambo 

Ngenxa yobukho bexabiso elikhulu le-flame retardants (i-mineral powder) kwiikhompawundi zekhebula ze-HFFR, ezibangela i-viscosity ephezulu kunye nokungahambi kakuhle ngexesha lokucubungula; I-viscosity ephezulu yenza kube nzima ukuba i-motor idonsa ngexesha le-extrusion, kwaye i-fluidity embi iphumela kwixabiso elincinci leglue eliveliswa ngexesha lokukhupha. Ke, xa umzi-mveliso wentambo ukhupha iintambo ezingenazo i-halogen, ukusebenza kakuhle yi-1/2-1/3 kuphela yentambo ye-polyvinyl chloride.

Ngomlinganiselo othile we-silicone kwifomula, kungekuphela nje ukusetyenzwa njengokuqukuqela okuphuculweyo kodwa nokufumana i-flame retardancy engcono kwizinto eziphathekayo.
