Dab tsi yog cov roj silicone emulsion?
Ua ntej, ob lub tswv yim yuav tsum tau to taub:
Silicone Roj: Feem ntau yog hais txog linear polysiloxanes (xws li Sadethyl Silicone Roj). Nws yog ib qho tsis muaj kob, tsw ntxhiab, tsis - pakic, thiab tsis {volatile oily kua. Nws cov molecular caj qaum muaj silicon {{}}}}}}}}}}}}}}} pawg muaj cov organic pab pawg xws li methyl. Cov qauv no muab cov roj Silicone tsawg kawg nkaus, zoo heev thiab kub tsis kam, tshuaj lom neeg inertness, thiab hydrophobicity.
Emulsion: ib qho kua tawg nyob rau hauv cov kua tsis muaj zog hauv daim ntawv ntawm cov tee dej me me. Cov roj silicone emulsions yog discicone roj hauv dej, feem ntau yuav tsum tau txais kev pab ntawm emulsifieve thiab cov neeg kho tshuab siab (xws li homogenization) los ua lub kaw lus ruaj khov.
Silicone roj tso tawm cov neeg sawv cev yog ua los ntawm diluting cov roj silicone roj emulsion nrog dej thiab ua paug lossis txhuam nws mus rau cov pwm nto. Cov ntaub ntawv no muaj cov ntaub nyias nyias nyias, txuas ntxiv, hydrophobic teeb meem, tso cai rau kev sib cais du ntawm ib feem ntawm cov pwm.
Cov tub ntxhais zoo ntawm cov roj silicone pa raws li tso cov neeg sawv cev
Piv rau cov yeeb yam cov kuab tshuaj -.
Kev Nyab Xeeb Kev Nyab Xeeb:
Dej -} х} dil} based} based organ dil organic organic (voc) cov pa hluav taws xob (VOC)
Tsis - flammable thiab tsis -}}}}}}}} Cov ntaub ntawv tawg: Qhov no tshem tawm cov phom tua thiab ua kom muaj kev nyab xeeb rau hluav taws thiab thauj mus los.
Kev ua tiav zoo:
Yooj yim rau Dilute: Qhov kev xav tau yooj yim tuaj yeem hloov kho tau yooj yim nrog dej kom tau raws li sib txawv.
Cov kev sib cais: cov emulsion ua ib qho kev sib cais hauv dej, ua kom nws yooj yim rau tshuaj tsuag thiab tso nyiaj rau cov pwm tsis zoo ntawm cov pwm nto.
Zoo heev tso:
Tsis tshua muaj qhov tseem ceeb saum npoo
Semi - {{{1} Txoj kev ua yeeb yaj kiab zoo nkauj thiab durabiling}, enterabling ntau qhov kev tso tawm thiab txhim kho ntau lawm.
Kev cuam tshuam tsawg kawg ntawm ntu:
Silicone roj yog cov kab mob siab tshaj plaws thiab feem ntau tsis hnov mob nrog cov khoom siv.
Lub txiaj ntsig zaj duab xis yog heev nyias thiab niaj hnub nyias, nyias ua nyias lub pwm pwm lub ntsej muag thiab tsis txhob muaj cov duab kos xws li blemishes lossis ntses.
Yig:
Txij li nws yog infinitely dilutable nrog dej thiab muab siab kom pom zoo efficiency, tus nqi ib daim ntawv thov yog tsawg.
Chaw thov
Silicone roj tso tawm cov neeg sawv cev tau siv dav hauv ntau yam kev lag luam, tshwj xeeb yog cov uas yuav tsum tau tso ua haujlwm siab:
Polyurethane (PU) Kev Lag Luam: Qhov chaw ua haujlwm loj tshaj plaws. Siv nyob rau hauv kev tsim cov pu npuas (xws li rooj zaum hauv rooj plaub ntug, xws li cov rooj zaum), xws li chais thiab khau soles), thiab pU potting cov ntaub ntawv.
Roj Hmab Kev Lag Luam: Siv hauv cov txheej txheem moulding thiab vulcanization ntawm ntau cov khoom siv roj hmab, xws li cov log tsheb, ntsaws ruaj ruaj, thiab hoses.
Composites kev lag luam: siv rau pwm Tshaj tawm cov fiberglass txhawb cov yas (fiber ntau cov khoom, nkoj Hulls, thiab Cua Turbine Pades.
Cov kev lag luam plastics: Siv kev txhaj tshuaj molding thiab compression moulding txheej txheem.
Kev lag luam ua khoom noj: zaub mov {{{{{{{{{{{}}}}}}}}}} Cov khoom tso tawm ntawm conficone thiab cov khoom ci (xws li pwm thiab ci cov tais).
Nrhiav Kev Lag Luam: Siv los ua cov tub ntxhais xuab zeb qhia tus neeg sawv cev hauv cov hlau casting.
Precast qhob: siv rau pwm tawm kom ua tiav cov qhob pob zeb du.
Kev faib tawm thiab xaiv cov roj silicone roj emulsions
Tsis yog txhua yam siicone roj emulsions tau tsim sib npaug. Ntau hom tuaj yeem xaiv raws li kev xav tau:
Zoo tib yam Dimethyl Silicone roj emulsion thiab kev xaiv feem ntau thiab kev lag luam, haum rau feem ntau cov pwm tso tawm.
High - Viscosity Silicone Roj Emulsion: Ua kom cov neeg tsiv teb tsaws chaw ua haujlwm zoo, tso cai rau cov pwm txuas ntxiv.
Hloov cov roj silicone roj emulsions:
Hydroxy Silicone roj emulsion: muaj cov ntoo khaub lig zoo heev}} Txoj kev txuas thiab cures ntxiv rau ntawm cov ntawv thov kom tso tawm. Nws yog ib qho khoom siv hauv paus rau "semi-}} Cov khoom siv sib npaug ruaj khov."
Amino Cov Khoom Siv Hluav Taws Xob Zoo Tshaj Plaws: xws li cov pwm pwm), muab sijhawm ntev dua -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} kav cov pwm tso tawm.
Epoxy -} hloov cov roj silicone
Khoom noj khoom haus - qib thiab kws tshuaj paus qib silicone
Xaiv cov ntsiab lus tseem ceeb:
Yuav tsum muaj cov kev xav tau: yog tias cov voj voog siab yog qhov yuav tsum tau, xaiv lub siab - viscosity los yog hloov kho (piv txwv li hydroxy) silicone roj emulsion.
Cov txheej txheem uas yuav tsum tau ua: yog tsuag, luam tawm, xaiv ib qho uas tau hloov kho, xaiv qhov tsis xws luag xws li "cov pits."
Pwm Cov Khoom Siv: cov pwm ntxig (piv txwv li, gypsum, ntoo) yuav tsum tau emulsion nrog ntau dua concentration lossis sib txawv permeability.
Kev Siv thiab Kev Ceev Faj
Dilution: Dilute nrog dej (dej uas muaj kev phom sij yog qhov xav tau) rau cov kev pom zoo (piv txwv li 1%) thiab do kom huv si.
Pwm Tu: Ua ntej siv, ua kom huv cov pwm kom tshem cov neeg sawv cev thiab cov av uas muaj cov yeeb yaj kiab qub thiab cov pwm tso tawm.
Daim Ntawv Thov: Tshuaj Tsuag, Txhuam Hniav, Los So. Txau muab cov yeeb yaj kiab uas tsis tshua nyiam tshaj plaws.
Kom qhuav / Zaj duab xis Tsim: Tom qab thov, cia cov dej kom ua tiav cov duab siliconorate thiab ua tiav cov duab silicone roj rau ntawm pwm nto. Yog tias tsim nyog, kub ntawm qis kub los txhawb cov dej evaporation thiab zaj duab xis tsim.
Cov kev ceev faj:
STABILITY: Cov emulsion yuav tsum tau tiv thaiv los ntawm khov thiab caij sov siab kub, vim qhov no yuav ua rau rhuav tshem thiab ua tsis tau zoo.
Delamination: lub caij nyoog sawv yuav ua rau muaj kev cuam tshuam. Co kom huv si ua ntej siv.
Kev paug: zam kev tsis huv, raws li drifting paug yuav paug txoj haujlwm ib puag ncig ua haujlwm thiab thaj chaw tsis xav tau pwm tso tawm.
Tshaj tawm -} kev ua: rau cov khoom lag luam uas yuav tsum tau ua cov kev sib tw ua ke, ntsuas qhov cuam tshuam ntawm cov roj silicone roj nyob rau ntawm kev sib raug zoo thiab txau.
Cov roj uas silicone, nrog lawv cov kev tiv thaiv ib puag ncig, muaj txiaj ntsig zoo, tau dhau los ua lub zog tshiab ntawm cov neeg sawv cev ua haujlwm niaj hnub. Los ntawm kev xaiv ntau hom ntawm cov roj silicone emulsions thiab lawv tuaj yeem ntsib cov kev xav tau pwm ua ke, ntawm cov kev lag luam tawm ntawm cov kev tsim khoom zoo rau qhov siab-}}}} xaus molding. Nrog cov kev tswj hwm ib puag ncig thiab kev nce qib thev naus laus zis zoo li cas, ua haujlwm siab.
