Waa maxay sababta daaha flake zinc-ka loogu kaydin waayay heerkul sare

La dhajiyay 2018-01-08Qalabka dahaarka ee Zinc wuxuu door muhiim ah ka ciyaaraa warshadaha casriga ah, codsiga daahan zinc flake ee wax soo saarka waa mid aad u badan, laakiin flake zinc laguma kaydin karo heerkul sare, taas oo ah sababta?

 


Sababtoo ah heerkulka sare waa sahlan tahay in uu keeno gabowga xal daahan, heerkulka kaydinta ee xal daahan flake zinc waa in la xakameeyo at 10 DEG C. Isla mar ahaantaana hoos qorraxda, daahan waa ay fududahay in polymerize, beddelo iyo xataa qashinka, sidaas darteed. waxaa fiican in hadhku ku jiro iftiinka.Muddada kaydinta ee rinjiga flake zinc ma fududa aad u dheer, sababtoo ah daahan dareere ah la diyaariyey waqti dheer, qiimaha pH waa ka fudud in kor loo qaado, oo ay sababtay gabowga daahan dareere ah ayaa la xoqay, tijaabooyinka ayaa muujinaya in wax qashinka ah ee chromatedacromet ka dib diyaarinta ansaxnimada heerkulka 20 DEG C muddo 30 maalmood ah, heerkulka 30 DEG C waa 12 maalmood, iyo muddo 40 deg.c ah oo keliya 5 maalmood.

 

Xalalka dahaarka ee Zinc waa in ay ku jiraan xaaladda heerkulka hooseeya, heerkulka sare ayaa ka dhigi doona daahan dareeraha ah ifafaale gabowga.
