Sodium Thiocyanate: Kemịkalụ ụlọ ọrụ mmepụta ihe nwere ọtụtụ ebumnuche
Ubi Ngwa Ndị Dị Mkpa
1. Mmepụta eriri acrylic
Sodium thiocyanate bụ ihe dị mkpa n'imepụta eriri acrylic. N'oge polymerization nke acrylonitrile, sodium thiocyanate na-arụ ọrụ dị ka ihe mgbaze, na-enye gburugburu ebe obibi kwụsiri ike maka mmeghachi omume polymerization. Ọ na-agbaze acrylonitrile monomers iji mepụta usoro polymerization otu, na-ebute eriri acrylic dị elu. A maara eriri acrylic maka iguzogide kemịkalụ dị mma, iguzogide iyi, na mkpuchi okpomọkụ, na-eme ka ha bụrụ ihe a na-ejikarị eme ihe n'uwe, ákwà ụlọ, na ákwà ụlọ ọrụ mmepụta ihe.
2. Ihe na-eme ka ihe nyocha kemịkalụ dị nro
Sodium thiocyanate dị mkpa na nyocha kemịkalụ.
