Keeb kwm ntawmSilicone Ntxiv / Silicone Masterbatch / Silosane Masterbatchthiab nws ua haujlwm li cas hauvHlau & Cable Tebkev lag luam?
Silicone additives nrog50% Ua Haujlwm Silicone PolymerKev tso tawm hauv cov cab kuj zoo li polyolefin lossis ntxhia, nrog daim ntawv ntawm granular lossis hmoov, siv dav ua cov kev pabcuam hauv xaim thiab kev lag luam cable. Cov khoom lag luam zoo liSiloxane MB50series ua haujlwm raws li roj nplua nyeem lossis rheological hloov kho hauv xaim & cable kev lag luam los ntawm kev them nyiaj corning corning hauv Tebchaws Meskas xyoo dhau los, tom qab ntawd tusLwm Yam Silicone Masterbatch MB50tshwm sim hauv kev ua lag luam nrog70% kev ua haujlwm silicone polymerDispier nyob rau hauv cov cab kuj zoo li silica, nrog daim ntawv ntawm granular zoo li, tom qab ntawd cov khoom lag luam los ntawm kev ua lag luam los ntawm lub xyoo 2004, nrog cov ntsiab lus silicone los ntawm 30-70% thiab cov hmoov av.
Cov lus qhia kev ua lag luam silicone masterbatch yuav tsum muaj cov ntsiab lus hauv qab no:
(1) Thaum twg ua haujlwm raws li cov roj nplua nyeem lossis rheological hloov kho, cov ntsiab lus ranges los ntawm 5 txog 50%
(2) cov cab kuj yuav tsum tau sib xws nrog silicone thiab tus neeg siv lub cim tseem ceeb yuav tsum tau txiav txim siab, yog li cov neeg siv tau xa mus rau nws thaum tsim cov mis. Yog tias cov pob zeb hauv pob zeb hauv pob zeb yog siv los ua tus cab kuj, cov hmoov npe yuav tsum tau qhia. Qhov dawb huv thiab zoo kawg ntawm inorganic hmoov yog qhov tseem ceeb rau cov neeg siv khoom, thiab dawb micron loj dua yuav tsum tau xaiv kom ntau li ntau tau rau kev tsim khoom.
Thaum ua haujlwm raws li kev ua haujlwm raws li roj ci lossis rheological modifiers
Rau cov khoom siv polyethylene
Raws li yog paub zoo, qhov tshwm sim ntawm "Shark tawv nqaij" feem ntau tshwm sim thaum cov xov hlau qis lossis cov xaim hluav taws xob (LLDPE) lossis cov roj av qis polyethylene (uplpe lossis poe). Extruded cross-txuas cov ntaub ntawv Polyethylene (txawm tias ib qho tawv nqaij sib txuas nrog cov tawv nqaij "tseem ceeb, vim qhov tsis txaus ntseeg ntawm lubrication system nyob rau hauv cov khoom siv. Kev xyaum thoob ntiaj teb no yog ntxiv cov nyiaj fluoropolymers rau cov qauv, tab sis tus nqi yog qhov siab thiab daim ntawv thov txwv.
Nrog me me ntawmultra-siab molecular hnyav silicone(0.1-0.2%) rau polyethylene lossis tus ntoo khaublig sib txuas tau zoo tiv thaiv cov tawv nqaij "shark". Nyob rau tib lub sijhawm, nrog nws lubrication nyhuv, nws tuaj yeem txo cov torque kom tiv thaiv kom tiv thaiv lub cev muaj zog los ntawm kev nres tsheb.
Silicone siv tau siv cov roj nplua nyeem, vim nws qhov tsawg kawg nkaus ntxiv, yuav tsum muaj tusyees faib cov khoom kom nws ua haujlwm thaum ua haujlwm. Vim yog cov tshuaj lom neeg inertness ntawm silicone, nws yuav tsis hnov tshuaj nrog cov cheebtsam hauv cov mis. Nws raug nquahu tias lub cable khoom siv Hoobkas txha hniav sib tov sib xyaw ua ke rau hauv cov txheej txheem granulation kom yooj yim los pab txhawb kev siv lub cable.
RauHalogen Dawb nplaim retardent (HFFRR) CABLE sib txuas
Vim tias muaj cov nplaim hluav taws xob loj (cov ntxhia pob zeb (cov ntxhia pob zeb) hauv HFFRR Cable compounds, uas tshwm sim lub siab viscosity thiab tsis zoo ntws thaum ua; Lub viscosity siab ua rau nws nyuaj rau lub cev muaj zog rau luag thaum lub sij hawm extrusion, thiab kev ua tau zoo ntawm cov kua nplaum me me ntawm lub sijhawm extrusion. Yog li, thaum lub thawv cable extrudes halogen-dawb cables, kev ua tau zoo yog 1 / 2-1 / 3 ntawm polyvinyl clesride cable.
Nrog rau qee qhov nyiaj ntawm silicone hauv cov qauv, tsis yog ua zoo li zoo li muaj kev txhim kho tab sis kuj tau txais cov nplaim taws zoo dua rau cov khoom siv.
