Hauv lub neej niaj hnub, cov roj silicone yog nyob txhua qhov chaw -los ntawm cov khoom siv silicone thiab cov cua sov- xa xov xwm hauv chav kuaj roj da dej mus rau cov ntawv thov kev lag luam xws li pwm tso tawm thiab lubrication. Txawm li cas los xij, txawm tias ntawm cov roj dimethyl silicone, tuaj yeem muaj qhov sib txawv tseem ceeb ntawm - cov khoom zoo thiab qhov nruab nrab.

Yog li, koj tuaj yeem txiav txim siab li cas tias cov roj silicone tiag tiag yog cov khoom ua tau zoo tshaj plaws? Niaj hnub no, peb yuav tshawb xyuas cov yam ntxwv ntawm siab - zoo silicone roj los ntawm plaub qhov kev pom tseem ceeb.

I. Nthuav thiab Purity

High transparency, colorlessness, thiab odorlessness yog thawj impressions ntawm ib tug hwm silicone roj.

Cov yam ntxwv no tsis yog kev zoo nkauj xwb; lawv ncaj qha cuam tshuam qhov khoom ntawm qhov purity. Ib qho xim me me (xws li daj daj daj) lossis cov ntxhiab tsw ntxhiab feem ntau qhia tias muaj cov khoom siv hluav taws xob, cov khoom oxidation, lossis lwm yam khoom siv los ntawm kev tsim khoom.

Rau siab - cov ntawv thov kawg, tshwj xeeb tshaj yog hauv cov tshuaj pleev ib ce, kev tu tawv nqaij, thiab cov khoom tu tus kheej, tsis muaj xim thiab tsis muaj ntxhiab yog qhov yuav tsum tau ua. Qhov no ua kom ntseeg tau tias cov xim qub, cov tshuaj tsw qab, thiab cov yam ntxwv ntawm cov qauv tseem tsis hloov pauv, muab cov neeg siv khoom nrog kev paub meej ntawm cov neeg siv khoom.

Rau cov ntawv thov kev lag luam, kev hnov ​​​​ntxhiab purity yog qhov qhia tau sai thiab ua tau zoo ntawm batch sib xws thiab tshuaj inertness.

II. Tshuaj Stability

High purity, tsis muaj impurity cov ntsiab lus, thiab tsis tshua muaj volatility yog lub ntsiab tseem ceeb uas txiav txim siab txog kev cia siab rau thiab kev pab cuam lub neej ntawm silicone roj nyob rau hauv cov kev xav tau.

Qhov no yog ib qho ntawm cov cim tseem ceeb tshaj plaws ntawm siab -cov roj silicone zoo, cuam tshuam ncaj qha rau nws lub peev xwm ua haujlwm tsis tu ncua nyob rau lub sijhawm ntev.

Purity Yog Lub Foundation

Cov impurities muaj xws li tsis tsuas pom hais tab sis kuj microscopic contaminants xws li:

Ionic impurities (chlorine, sodium, potassium, thiab lwm yam)

Cov no feem ntau suav hais tias yog "cov neeg tua tsis pom" hauv kev siv hluav taws xob. Txawm tias muaj pes tsawg tus ionic residues tuaj yeem ua rau corrosion, hluav taws xob to, thiab luv circuits. Raws li qhov tshwm sim, cov roj hluav taws xob- qib silicone roj yuav raug rau cov kev cai purity nruj heev.

Catalyst residues

Cov catalysts residual tuaj yeem cuam tshuam tsis zoo rau lub sijhawm ntev - kev ruaj ntseg ntawm cov roj silicone thiab tseem tuaj yeem ua kom tawg sai dua nyob rau hauv siab - qhov kub thiab txias.

Tsawg Volatility kom ntseeg tau tias thermal stability

Cov ntsiab lus tsis hloov pauv yog hais txog qhov feem pua ​​​​ntawm qhov hnyav tau ntsib los ntawm cov roj silicone thaum raug kub hnyiab.

Tsawg volatility qhia tau tias thermal stability ntau dua, txo qhov muaj feem ntawm evaporation, ziab, coking, lossis fume tiam thaum ua haujlwm.

Txawm siv nyob rau hauv LED tsav tsheb fais fab khoom siv, tsheb cav compartments, los yog siab -kub molding daim ntaub ntawv, tsis tshua muaj volatility yog ib qho tseem ceeb kom ntseeg tau tias ntev - kev ua tau zoo.

III. Precise Viscosity Control

Cov viscosity meej, qhov sib txawv me me ntawm kev ua siab ntev, thiab cov khoom zoo heev - rau - batch sib xws muaj kev cuam tshuam rau cov chaw tsim khoom cov txheej txheem kev tswj hwm thiab kev cog lus kom zoo.

Viscosity yog ib qho tseem ceeb ntawm lub cev muaj zog ntawm silicone roj. Txawm li cas los xij, kev ua tiav qhov tseeb viscosity tus nqi yog txawv los ntawm kev tswj kom zoo ib yam viscosity nyob rau hauv ntau lawm batch.

Qhov tseem ceeb ntawm Precision thiab sib npaug

Rau cov qauv tsim qis qis, txawm tias me me viscosity variations ntawm batches tuaj yeem cuam tshuam qhov kev ntxhib los mos, kev coj tus cwj pwm, thiab kev ua haujlwm ntawm cov khoom kawg, xws li cream, coatings, thiab sealants.

Cov kev hloov pauv no feem ntau xav tau kev hloov kho, ua rau cov nqi ntau lawm, kev sim ntxiv, thiab cov teeb meem zoo.

Lub Foundation ntawm Kev Ua Haujlwm

Hauv daim ntawv thov lubrication, viscosity txiav txim siab roj zaj duab xis tuab thiab thauj khoom - nqa peev xwm.

Hauv kev siv damping, viscosity ncaj qha cuam tshuam rau lub zog damping thiab cov yam ntxwv ua haujlwm.

Cov roj silicone nrog cov viscosity meej thiab ruaj khov muab lub hauv paus txhim khu kev qha rau siab -kev ua tau zoo thiab ua kom pom tseeb ntawm cov chaw tsim khoom nrhiav kev ua tau zoo.

IV. Molecular Structure Regularity

Ib zaug -theem synthesis, qhov tsis muaj kev sib xyaw, thiab cov saw hlau molecular zoo ib yam sawv cev rau qib siab tshaj plaws ntawm kev tsim cov roj silicone.

Qhov kev ntsuas no paub qhov txawv ntawm cov roj silicone tiag tiag los ntawm cov khoom siv tau zoo thiab qhia txog lub tswv yim tseem ceeb tom qab lawv cov khoom tsim.

Ib leeg -Txoj Kev Synthesis vs. Blending

Ib leeg -Txoj kev Synthesis

Zoo li ua tib zoo ci lub ncuav mog qab zib los ntawm kos, txoj kev no ncaj qha tsim cov roj silicone nrog qhov xav tau qhov hnyav thiab viscosity los ntawm kev tswj xyuas meej ntawm cov tshuaj tiv thaiv.

Cov khoom uas tshwm sim feem ntau nthuav tawm qhov nqaim molecular hnyav faib thiab cov qauv molecular heev.

Sib tov

Zoo ib yam li kev sib xyaw cov ncuav qab zib ntawm ntau qhov sib txawv ua ke, kev sib xyaw ua ke muaj lub cev sib xyaw ua ke siab -viscosity thiab qis- viscosity silicone roj kom ua tiav lub hom phiaj viscosity.

Txawm hais tias txoj hauv kev no hloov pauv tau thiab tus nqi- ua tau zoo, nws feem ntau ua rau muaj qhov dav dua qhov hnyav ntawm molecular faib thiab tsawg dua cov saw hlau molecular ntev.

Qhov zoo ntawm Uniform Molecular Structure

Superior viscosity-kub kev ua tau zoo, nrog tsawg dua viscosity hloov nyob rau hauv ntau qhov kub thiab txias.

Txhim kho shear stability, tswj viscosity nyob rau hauv kev sib xyaw sib xyaw, twj, lossis kev sib txhuam.

Tsawg volatility vim qhov txo qis ntawm -molecular- cov khoom hnyav.

Ntau cov khoom zoo sib xws, ua rau cov yeeb yaj kiab smoother thiab txhim kho gloss.

Xaus

Xaiv lub siab - zoo silicone roj muaj ntau dua li xaiv cov khoom raws li ib qho kev qhia tshwj xeeb. Nws yuav tsum tau soj ntsuam kev sib xyaw ua ke ntawm kev hnov ​​​​ntxhiab tsw, tshuaj lom neeg ruaj khov, viscosity sib xws, thiab cov qauv molecular tsis tu ncua.

Thaum koj daim ntawv thov xav tau qhov tshwj xeeb ntawm daim tawv nqaij, qhov ntev - ruaj khov, kev tiv thaiv txhim khu kev qha, lossis kev tsim khoom zoo, kev nkag siab txog plaub yam tseem ceeb no yog qhov tseem ceeb. Lawv muab lub hauv paus rau kev xaiv cov roj silicone uas txhim khu kev qha tshaj plaws thiab ua kom zoo tshaj plaws hauv koj cov khoom kawg.
