Sodium propionate CAS 137-40-6
Sodium propionate yog xim tsis muaj pob tshab siv lead ua, granule lossis dawb crystalline hmoov. Nws tsis muaj ntxhiab los yog muaj me ntsis propionic acid tsw. Nws yog yooj yim deliquescent, heev soluble nyob rau hauv dej, soluble nyob rau hauv ethanol, thiab me ntsis soluble nyob rau hauv acetone.

1. Ceramic kev lag luam
(1) Opacifiers thiab whitening agents: siv rau hauv glazes rau architectural ceramics, sanitary ceramics, niaj hnub ceramics thiab handicraft ceramics, los ntawm kev tsim baddeleyite crystals kom tawg lub teeb, yog li txhim kho lub whiteness thiab nkaum lub zog ntawm lub glaze.
(2) Txhim kho kev sib txuas ntawm lub cev thiab glaze: txhim kho lub zog sib txuas ntawm lub cev ceramic thiab txheej glaze, txo qhov kev pheej hmoo ntawm kev tawg.
(3) Txhim kho lub hardness ntawm glaze: ua cov khoom ceramic ntau hnav-resistant thiab khawb-resistant.
2. iav thiab enamel
(1) Emulsified iav: siv los ua iav opalescent, nce pob tshab thiab kev ntxhib los mos.
(2) Enamel glaze: siv los ua opacifier los txhim kho cov xim dawb thiab sib xws ntawm cov khoom enamel.
3. Cov khoom siv refractory
Siv rau hauv cov ntaub ntawv ramming, castables thiab tshuaj tsuag txheej rau iav kilns, vim lawv qhov siab melting point (2500 ℃) thiab corrosion kuj, lawv tuaj yeem tiv taus qhov kub thiab txias.
4. Sib tsoo xov xwm
Zirconium silicate hlaws yog siv rau kev sib tsoo ultrafine hauv cov txheej, number case, tshuaj pleev ib ce thiab lwm yam lag luam, hloov cov iav hlaws. Lawv muaj hardness siab (Mohs hardness 7.5), hnav tsis kam thiab tshuaj stability.
5. Lwm qhov chaw
(1) Yas filling: Txhim kho cov cua sov thiab rwb thaiv tsev ntawm cov ntaub ntawv xws li epoxy resin thiab silicone.
(2) Kev tshawb fawb kho mob: Raws li tus neeg nqa khoom lossis txheej txheej, nws yog siv rau cov tshuaj tiv thaiv kev tso tawm lossis cov khoom siv ua haujlwm (xws li liab glaze ntawm Suav liab ceramics).
Nuclear zog thiab kev lag luam tub rog: Zirconium alloys yog siv los ua cov khoom siv hluav taws xob hauv hluav taws xob, thiab cov khoom siv hluav taws xob ntawm zirconium silicate tau kawm thiab siv hauv cov xwm txheej kho mob tshwj xeeb.
