Cov silicones yog cov khoom siv tshwj xeeb uas muaj cov yam ntxwv ntawm cov khoom sib xyaw ua ke ntawm cov khoom inorganic thiab cov organic. Lawv qhia txog qhov tsis tshua muaj qhov nro ntawm qhov chaw, qhov tsis tshua muaj viscosity-kub coefficient, siab compressibility, siab gas permeability, nrog rau kev tiv taus zoo heev rau qhov kub thiab txias heev, oxidation, weathering, dej, thiab tshuaj lom neeg. Lawv kuj tsis muaj tshuaj lom, physiologically inert, thiab muaj cov khoom dielectric zoo heev.
Cov khoom siv silicone yog siv dav rau kev kaw, kev nplaum, kev ua kom lubrication, kev pleev xim, surfactants, defoaming, waterproofing, insulation, thiab ua fillers. Kev tsim cov silicones muaj ntau kauj ruam nyuaj:
•Silica thiab carbon raug hloov pauv ntawm qhov kub siab mus rau hauv siloxanes.
•Cov hlau siloxane intermediates yog chlorinated, yielding chlorosilanes.
•Hydrolysis ntawm chlorosilanes tsim cov siloxane units nrog rau HCl, uas tom qab ntawd distilled thiab purified.
•Cov intermediates no tsim cov roj silicone, resins, elastomers, thiab lwm yam polymers nrog cov khoom sib txawv thiab kev ua tau zoo.
Thoob plaws hauv cov txheej txheem no, cov chaw tsim khoom yuav tsum tshem tawm cov seem tsis xav tau, dej, thiab cov khoom me me gel kom ntseeg tau tias cov khoom zoo. Yog li ntawd, cov txheej txheem lim dej ruaj khov, ua haujlwm tau zoo, thiab yooj yim rau kev saib xyuas yog qhov tseem ceeb.
Kev Sib Tw ntawm Cov Neeg Siv Khoom
Ib lub tuam txhab tsim cov silicone xav tau ib txoj hauv kev zoo dua los cais cov khoom khov thiab nrhiav cov dej thaum lub sijhawm tsim khoom. Lawv cov txheej txheem siv sodium carbonate los ua kom cov hydrogen chloride tsis muaj zog, uas ua rau cov dej thiab cov khoom khov seem. Yog tsis muaj kev tshem tawm zoo, cov khoom seem no tuaj yeem tsim cov gels, ua rau cov khoom viscosity nce ntxiv thiab ua rau qhov zoo tsis zoo.
Ib txwm muaj, qhov kev ntxuav no yuav tsum tau uaob kauj ruam:
•Cais cov khoom khov ntawm cov silicone intermediates.
•Siv cov tshuaj ntxiv kom tshem tawm cov dej.
Tus neeg muas zaub tau nrhiav ib qhokev daws teeb meem ib kauj ruammuaj peev xwm tshem tawm cov khoom khov, cov dej me me, thiab cov gels, yog li ua kom yooj yim rau cov txheej txheem, txo cov khoom pov tseg, thiab txhim kho kev ua haujlwm ntau lawm.
Kev daws teeb meem
Great Wall Filtration tau tsim covSCPQhov tob ntawm seriesLimCov Modules, tsim los tshem tawm cov khoom khov, cov dej seem, thiab cov khoom me me hauv ib kauj ruam.
•Kev Siv TshuabCov SCP modules sib xyaw cov cellulose fibers zoo (los ntawm cov ntoo deciduous thiab coniferous) nrog cov av diatomaceous zoo thiab cov cationic charge carriers.
•Kev Khaws Cia Ntau Yam: Kev ntsuas lim dej nominal los ntawm0.1 txog 40 µm.
•Kev Ua Tau Zoo Tshaj Plaws: Kev ntsuam xyuas tau pom tias muajSCPA090D16V16Smodule nrog1.5 µm khaws ciaraws li qhov tsim nyog tshaj plaws rau daim ntawv thov no.
•Lub tshuab: Muaj peev xwm nqus dej tau zoo ua ke nrog cov qauv qhov zoo tagnrho ua kom ntseeg tau tias cov gels thiab cov khoom me me uas hloov pauv tau.
•Tsim Qauv: Nruab rau hauv cov hlau tsis xeb, kaw cov tsev kaw nrog cov chaw lim dej los ntawm0.36 m² txog 11.7 m², muab kev ywj pheej thiab kev ntxuav yooj yim.
Cov txiaj ntsig
•Ua tiav kev tshem tawm cov khoom khov, dej me me, thiab cov gels hauv ib kauj ruam xwb.
•Ua kom yooj yim rau kev ua haujlwm ntau lawm, tshem tawm qhov xav tau ob txoj haujlwm sib cais.
•Txo cov khib nyiab los ntawm cov khoom lag luam thiab txhim kho kev ua haujlwm ntawm cov khoom.
•Xa kev ua haujlwm lim dej ruaj khov thiab txhim khu kev qha yam tsis muaj kev poob siab loj.
Kev Pom Zoo
Cov Lus Nug Feem Ntau
Q1: Vim li cas kev lim dej thiaj tseem ceeb hauv kev tsim cov silicone?
Kev lim dej ua kom ntseeg tau tias tshem tawm cov khoom khov tsis xav tau, cov dej me me, thiab cov khoom me me uas tuaj yeem cuam tshuam tsis zoo rau qhov zoo ntawm cov khoom, kev ruaj khov, thiab viscosity. Yog tsis muaj kev lim dej zoo, cov silicones yuav ua tsis tau raws li cov qauv kev ua tau zoo.
Q2: Cov teeb meem twg uas cov chaw tsim khoom ntsib hauv kev ntxuav silicone?
Cov txheej txheem ib txwm muaj yuav tsum muaj ntau kauj ruam—cais cov khoom khov thiab tom qab ntawd siv cov khoom ntxiv los tshem tawm cov dej. Cov txheej txheem no siv sijhawm ntau, kim heev, thiab tuaj yeem tsim cov khib nyiab ntxiv.
Q3: Yuav ua li cas thiaj ua tau li ntawdSCPQhov tob ntawm seriesLimModule daws cov teeb meem no?
Cov modules SCP ua kom muaj kev nyab xeebkev lim dej ib kauj ruam, tshem tawm cov khoom khov, cov dej seem, thiab cov gels. Qhov no ua rau cov txheej txheem yooj yim dua, txo cov khib nyiab, thiab txhim kho kev ua haujlwm ntau lawm.
Q4: Lub tshuab lim dej yog dab tsi?SCPcov modules?
Cov modules SCP siv cov qauv sib xyaw ua ke ntawm cov cellulose fibers zoo, cov av diatomaceous zoo, thiab cov cationic charge carriers. Qhov kev sib xyaw ua ke no ua kom muaj zog adsorption ntawm dej thiab kev khaws cia ntawm cov gels thiab cov khoom me me uas deformable.
Q5: Cov qhab nia khaws cia twg muaj?
SCP modules muab ib qhonominal filtration ntau yam ntawm 0.1 µm txog 40 µmRau kev ua cov silicone, feem ntau pom zoo kom siv SCPA090D16V16S module nrog qhov ntsuas khaws cia 1.5 µm.
