Hydrophobic precipitated silica: ib qho kev ua haujlwm ntxiv ntxiv rau cov ntawv thov sib yuaj
Khoom Txheej Txheem
Hydrophobic precipitated silica, ib qho kev hloov kho cov khoom siv hluav taws xob, cov txheej txheem hydrophilic uas muaj cov organosilane (piv txwv li, dimethyl lossis chimethyl linane). Qhov kev hloov kho no imparts tshwj xeebDej Xiav Dej, siab dispersibility, thiabRheological tswj lub peev xwm, ua rau nws tsis tseem ceeb nyob rau hauv kev lag luam xws li txheej ci, plastics, roj hmab, thiab tshuaj tshwj xeeb. Nrog ib qho kev ua kom loj me me hauv cov nanometer ntau thiab twv txiaj ntsig txog cov txiaj ntsig ntawm cov txiaj ntsig ntawm cov txiaj ntsig ntawm cov txiaj ntsig ntawm hydrophobicity.
Qhov tseem ceeb Daim Ntawv Thov & Cov Nyiaj Pab
**1.Anti {- thaiv cov neeg sawv cev rau cov yas thiab yas ua yeeb yaj kiab
Lub tshuab: Ua raws li aKev hloov pauv deg degLos ntawm kev txo qis inter - zaj duab xis adhesion los ntawm nws cov qauv microporous thiab qis lub zog.
Qhov Zoo:
Tiv thaiv zaj duab xis txheej los ntawm cov khaubncaws sab nraud povtseg ntawm kev cia khoom lossis kev thauj mus los, ua kom muaj kev tsis sib haum xeeb hauv PE / PP / PVC Films.
Saib xyuas zaj duab xis transparency (ntau dua los yog sib npaug nrog 96% lub teeb kev hloov chaw) thiab lub zog kho zog thaum txo cov coefficients (cof) txog li 50%.
Ua raws li FDA thiab EU ROHS cov qauv, haum rau cov zaub mov - thawv ntim.
**2.Anti {- kev taw qhia & thixotropic tus neeg sawv cev hauv cov xim pleev xim / inks
Lub luag hauj lwm: Ua A3D hydrogen -} bonded networkTxhawm rau tiv thaiv cov xim av thiab txhim kho sag tiv taus.
Kev Saib Xyuas Kev Ua Haujlwm:
Reduces settling by >90% nyob rau hauv high - viscosity txheej (piv txwv li, epoxy, polyurethane).
Pab txhawb nqatxoj kev pom muajthiablevingLos ntawm kev sib tw viscosity rov qab (thixotrotropy Performance index: 3.0-5.0).
Kev zoo dua thiab muaj kev ruaj ntseg ruaj khov nyob rau hauv cov kuab tshuaj {{0} raws cov ntsiab lus, txo cov neeg sawv cev ntub dej los ntawm 20-30%.
**3.Ntws AID hauv Cov Hluav Taws Xob Hluav Taws Xob thiab hmoov Txheej Txheej
Kev ua yam ua hauj: Improves powder fluidity and prevents caking under humidity (RH >60%).
Ntawv muaj: NtsibGA 578-2005thiabISO 14520-1Cov qauv rau cov hmoov hluav taws qhuav.
Cov ntaub ntawv txheej txheem:
Qhov loj me me: D90<40 μm for uniform sprayability.
Kev nqus dej noo:<0.5% (24h, 25°C/75% RH) .
**4.Kev txhawb nqa chais rau silicone elastomers
Ua yeeb yam:
Yuav nce tensile lub zog (txog 12 MPA) thiab kua muag yeem tawm hauv LSR (cov kua Silicone Roj Hmab).
Ua rau cov chaw thau khoom siab (30-50 wt%) yam tsis muaj kev cuam tshuam cov txheej txheem, zoo tagnrho rau cov khoom siv kho mob.
Txhim kho thermal stability (kev pabcuam kub: -50℃rau +200 degree).
**5.Dielectric hloov kho rau cable rwb thaiv tsev
Cov txiaj ntsig:
Lowers dielectric tas li (ε<2.8) and reduces energy loss in high-voltage cables .
Improves insulation resistance by >10 ^ ____ 15 ω · cm, sab lajIec 60243Cov Qauv.
**6.Anti - abrasive ntxiv engineering tej hniav
Cov Ntawv Thov:
Boosts ScratchS SWREEN (ASTM D1044:<5% haze increase after 1,000 cycles) in polyamide and PBT composites .
Txhim kho cov tawv tawv saum npoo (rockwell m nplai: +15%) thaum tswj lub zog cuam tshuam.
**7.Kws muag tshuaj & Zaub mov {{{{{{}} qib ov - Ceg Caking tus neeg sawv cev
Kev ceev kev cai:
USP/EP-grade purity (SiO₂ >99.9%, Cov Hlau Hnyav<10 ppm) .
Ua tau zoo noo noo adsorption (txog 200% ntawm tus kheej - qhov hnyav) rau cov hmoov flangability hauv apis thiab zaub mov ntxiv.
