(1) acetylene
Kev tsim khoom siv vuam thiab txiav: lub nplaim taws ntawm acetylene thiab cov pa yuav ncav cuag 3100 degree thiab tau siv dav hauv kev ua hlau.
Tshuaj Kho Khoom Siv: Acetylene yog cov khoom siv raw rau kev tsim cov polyvinyl chloride (PVC), yas acrylic acid, thiab lwm yam.
(2) calcium
Cyanamide fertilizer maj mam-tso nitrogen fertilizer: nws yog hydrolyzed nyob rau hauv av mus ua Cyanamide (H2CN2), uas maj mam tso cov nitrogen.
Kev Txhim Kho Av: Nws tuaj yeem tswj cov av acidity thiab muaj tshuaj tua kab thiab anti-nroj (xws li sib ntaus sib tua (xws li kev ntaus nematodes).
(3) Metallurgical Kev Lag Luam
Tus neeg sawv cev hlau: nws yog siv los tsim cov hlau nrog lub siab yaj suab, xws li vanadium thiab tungsten, thiab txo lawv cov oxides.
Desulfurizing tus neeg sawv cev: nws tshem tawm cov txiv lws suav hauv cov hlau smelting.
(4) Lwm qhov Niche siv
Txiv hmab txiv ntoo siav: Cov acetylene uas tso tawm ua ke rau kev tsim cov ethylene, tab sis nws tau txwv nyob rau hauv European Union, Nyij Pooj, thiab lwm yam (residual kev txhawj xeeb).
Thaum Ntxov teeb pom kev zoo: Calcium carbide teeb tau ib zaug siv rau hauv mines thiab sab nraud thiab tam sim no muaj tsuas yog ua cov ntaub ntawv keeb kwm.
