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 lecingo 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 wefluoropolymers 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 ukuthintela 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.
