Keeb kwm ntawmSilicone additives / Silicone masterbatch / Siloxane masterbatchthiab nws ua haujlwm li cas hauvhlau & cable compoundskev lag luam?

Silicone additives nrog50% ua haujlwm silicone polymerdispered nyob rau hauv cov cab kuj zoo li polyolefin los yog ntxhia, nrog rau daim ntawv ntawm granular los yog hmoov, dav siv raws li kev pab nyob rau hauv hlau & cable kev lag luam. Cov khoom lag luam paub zoo liSILOXANE MB50series ua hauj lwm raws li lubricant los yog rheological modifier nyob rau hauv hlau & cable kev lag luam thiab nws yog thawj zaug qhia los ntawm Dow Corning nyob rau hauv lub tebchaws United States nees nkaum xyoo dhau los, ces lubTom ntej: SILICONE MASTERBATCH MB50tshwm sim hauv kev ua lag luam nrog70% functionalized silicone polymerdispersed nyob rau hauv cov cab kuj zoo li silica, nrog daim ntawv ntawm granular zoo li, ces cov khoom los ntawm Chengdu Silike tshwm nyob rau hauv lub lag luam los ntawm lub xyoo 2004, nrog silicone cov ntsiab lus los ntawm 30-70% thiab granular los yog hmoov daim ntawv.

Cov yam ntxwv ntawm kev lag luam silicone masterbatch yuav tsum muaj cov ntsiab lus hauv qab no:

(1) Thaum ua hauj lwm raws li lub roj nplua nyeem lossis hloov kho rheological, cov ntsiab lus ntawm 5 txog 50%

(2) Cov cab kuj yuav tsum tau sib xws nrog silicone thiab tus neeg siv lub ntsiab formula substrate yuav tsum tau txiav txim siab, nrog polymer lub npe qhia thiab yaj Performance index ntawm cov cab kuj, kom cov neeg siv tau xa mus rau nws thaum tsim cov qauv. Yog tias inorganic ntxhia hmoov siv los ua tus nqa khoom, lub npe hmoov yuav tsum tau qhia. Kev ua kom dawb thiab zoo ntawm cov hmoov tsis zoo yog qhov tseem ceeb rau cov neeg siv khoom, thiab cov hmoov dawb thiab micron loj yuav tsum raug xaiv kom ntau li ntau tau rau kev tsim khoom.

Thaum ua hauj lwm raws li lubricants los yog rheological modifiers

Rau cov khoom siv polyethylene

Raws li paub zoo, qhov tshwm sim ntawm "shark tawv" feem ntau tshwm sim thaum extruding polyethylene insulated los yog sheathed xov hlau thiab cables, tshwj xeeb tshaj yog thaum extruding linear low-density polyethylene (LLDPE) los yog ultra-low ntom polyethylene (ULDPE los yog POE). Extruded cross-linked polyethylene cov ntaub ntawv (txawm hais tias peroxide cross-linking lossis silane cross-linking) kuj qee zaum ntsib "shark skin" tshwm sim, vim tsis txaus xav txog lub lubrication system hauv cov khoom siv mis. Kev coj ua thoob ntiaj teb tam sim no yog ntxiv cov lej ntawm fluoropolymer rau cov qauv, tab sis tus nqi siab thiab daim ntawv thov raug txwv.

Nrog me me ntawmultra-siab molecular hnyav silicone(0.1-0.2%) rau polyethylene lossis cross-linked polyethylene tuaj yeem tiv thaiv kev tsim ntawm "shark tawv nqaij". Nyob rau tib lub sijhawm, nrog rau nws cov txiaj ntsig lubrication, nws tuaj yeem txo qhov extrusion torque kom tsis txhob rub lub cev muaj zog vim yog overload.

Silicone siv los ua cov roj nplua nyeem, vim nws qhov sib ntxiv me me, yuav tsum tau muab faib ua tus sib npaug hauv cov khoom kom nws ua haujlwm thaum lub sijhawm ua haujlwm. Vim yog cov tshuaj inertness ntawm silicone, nws yuav tsis hnov ​​​​mob nrog cov khoom hauv cov mis. Nws raug pom zoo tias cov khoom siv cable Hoobkas sib npaug sib xyaw silicone rau hauv cov txheej txheem plasticizing granulation los pab txhawb kev siv lub Hoobkas cable.

RauHalogen dawb nplaim retardant (HFFR) cable compounds 

Vim tias muaj cov nplaim hluav taws ntau ntau (cov hmoov ntxhia) hauv HFFR cable compounds, uas ua rau muaj viscosity siab thiab tsis muaj dej txaus thaum ua haujlwm; Lub siab viscosity ua rau nws nyuaj rau lub cev muaj zog rub thaum lub sijhawm extrusion, thiab cov dej tsis zoo ua rau cov kua nplaum me me uas ua rau lub sijhawm extrusion. Yog li, thaum lub Hoobkas cable extrudes halogen-dawb cables, qhov ua tau zoo tsuas yog 1/2-1/3 ntawm polyvinyl chloride cable.

Nrog rau qee qhov nyiaj ntawm silicone hauv cov mis, tsis tsuas yog ua haujlwm zoo li flowability txhim kho tab sis kuj tau txais cov nplaim hluav taws zoo dua rau cov khoom siv.
