Hydrogen-muaj roj silicone yog cov khoom siv silicone tseem ceeb, thiab nws txoj kev loj hlob tuaj yeem taug qab mus rau xyoo 1940s. Lub sijhawm ntawd, lub tuam txhab Asmeskas DuPont thawj zaug pom qhov muaj ntawm silicon thiab pib kawm nws. Nrog rau kev tshawb fawb tob zuj zus, tib neeg pom tias silicon muaj ntau yam khoom tshwj xeeb, xws li kub tsis kam, oxidation tsis kam, dej tsis kam, thiab lwm yam, yog li nws pib siv rau hauv ntau yam.
Nyob rau hauv txoj kev loj hlob ntawm hydrogen-muaj silicone roj, cov kws tshawb fawb txuas ntxiv mus tshawb nws cov txheej txheem synthesis thiab daim ntawv thov teb. Thawj hydrogen-muaj silicone roj yog tsim los ntawm cov tshuaj tiv thaiv ntawm sodium silicate thiab sulfuric acid, thiab tom qab ntawd los ntawm hydrolysis, neutralization, refining thiab lwm yam txheej txheem. Lub purity ntawm hydrogen-muaj silicone roj npaj los ntawm txoj kev no yog tsawg, thiab ib tug loj npaum li cas ntawm cov dej khib nyiab thiab cov pa khib nyiab yuav raug tsim nyob rau hauv cov txheej txheem ntau lawm, ua rau muaj kuab paug rau ib puag ncig. Raws li qhov tshwm sim, cov kws tshawb fawb tau pib tshawb nrhiav ntau dua ib puag ncig tus phooj ywg thiab cov txheej txheem synthesis zoo.
Nrog kev nce qib ntawm kev siv thev naus laus zis, tib neeg tau pom qee qhov kev sib raug zoo ntawm ib puag ncig thiab muaj txiaj ntsig zoo sib xws. Piv txwv li, cov roj silicone muaj hydrogen yog tsim los ntawm cov tshuaj tiv thaiv ntawm silicon hmoov thiab hydrogen ntawm qhov kub thiab txias. Cov roj hydrogen-muaj silicone npaj los ntawm txoj kev no muaj purity siab thiab zoo, thiab tsis tsim cov dej khib nyiab thiab cov roj pov tseg hauv cov txheej txheem tsim khoom. Tsis tas li ntawd, cov kws tshawb fawb kuj tau tsim qee txoj kev sib xyaw tshwj xeeb, xws li kev siv silane thiab hydrogen nyob rau hauv qhov kev ua ntawm catalyst cov tshuaj tiv thaiv los tsim hydrogen-muaj silicone roj, uas muaj ntau yam tshwj xeeb, xws li viscosity tsawg, siab flash point thiab thiaj li. ntawm.
Daim ntawv thov teb ntawm hydrogen-muaj silicone roj kuj tseem nthuav. Thaum pib, cov roj silicone muaj hydrogen feem ntau yog siv rau kev kho dej tsis zoo thiab roj pov thawj hauv textile, tawv, ntawv thiab lwm yam. Nrog rau kev txhim kho tas mus li ntawm kev ua tau zoo ntawm hydrogen-muaj roj silicone thiab kev txhim kho txuas ntxiv ntawm kev siv thev naus laus zis, nws daim ntawv thov teb tau txuas ntxiv mus rau aerospace, electronics, kev kho mob thiab lwm yam. Piv txwv li, nyob rau hauv aerospace teb, hydrogen-muaj silicone roj yuav siv tau los npaj cov khoom sib xyaw nrog cov khoom zoo xws li kub tsis kam, oxidation tsis kam, thiab tsis muaj dej. Hauv kev lag luam hluav taws xob, cov roj silicone uas muaj hydrogen tuaj yeem siv los npaj cov ntaub ntawv insulating thiab cov khoom siv hluav taws xob nrog cov khoom zoo heev. Hauv kev kho mob, cov roj silicone uas muaj hydrogen tuaj yeem siv los npaj cov pob qij txha thiab cov khoom siv kho mob nrog biocompatibility zoo heev.
Nyob rau hauv luv luv, hydrogen-muaj silicone roj, raws li ib tug tseem ceeb silicone khoom, tau undergone ntau theem ntawm txoj kev loj hlob, los ntawm cov thawj synthesis txoj kev mus rau expansion ntawm daim ntawv thov teb, thiab tau ntsib tas li kev tshawb fawb thiab innovation. Nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev thov nce ntxiv, daim ntawv thov kev cia siab ntawm hydrogen-muaj silicone roj yuav dav dua.
