Molao-motheo le melemo ea magnesium hydroxide flame retardant
Magnesium hydroxide ke setlala sa inorganic retardant, se nang le tebello e pharalletseng ea ts'ebeliso ea lisebelisoa tse entsoeng ka polymer.Magnesium hydroxide flame retardant e senya le ho ntša metsi ha e futhumala, e monya mocheso, e fokotsa mocheso oa lelakabe holim'a thepa ea polymer, 'me e liehisa mokhoa oa ho senyeha ha polymer ho ba boima bo tlaase ba limolek'hule.Ka nako e ts'oanang, mouoane oa metsi o lokollotsoeng o ka fokotsa oksijene holim'a thepa, o thibela ho chesa ha thepa.Ka hona, magnesium hydroxide flame retardant e na le melemo ea ho se chefo, mosi o tlase, 'me ha ho na tšilafalo ea bobeli.Ke sekoahelo sa lelakabe se nang le botsoalle tikolohong.
Bohlokoa ba ho fetola magnesium hydroxide
Leha ho le joalo, ha ho bapisoa le li-halogen-based flame retardants, magnesium hydroxide flame retardants e hloka chelete e ngata ea ho tlatsa ho finyella phello e ts'oanang ea ho thibela lelakabe, hangata ka holimo ho 50%.Hobane magnesium hydroxide ke ntho e sa sebetseng, ha e tsamaellane hantle le lisebelisoa tse thehiloeng ho polymer.Chelete e ngata ea ho tlatsa e tla ama thepa ea mechine ea lisebelisoa tse kopantsoeng.Ho rarolla bothata bona, hoa hlokahala ho fetola bokaholimo ba magnesium hydroxide ho ntlafatsa tšebelisano ea eona le lisebelisoa tse thehiloeng ho polymer, ho ntlafatsa ho qhalana ha eona ka thepa e kopaneng, ho eketsa ts'ebetso ea eona ea bokaholimo, ka hona ho fokotsa litekanyetso tsa eona, ho ntlafatsa ts'ebetso ea eona e thibelang mollo, le ho e boloka. kapa ho ntlafatsa thepa ea mochine ea lisebelisoa tse kopantsoeng.
Mekhoa ea ho fetola magnesium hydroxide
Hona joale, ho na le mekhoa e 'meli e tloaelehileng ea ho fetola magnesium hydroxide: mokhoa o omileng le mokhoa oa metsi.Phetoho ea mokhoa o omileng ke ho kopanya magnesium hydroxide e omileng le tekanyo e nepahetseng ea setlolo sa inert, ho e fafatsa ka sesebelisoa se kopanyang kapa ntho e 'ngoe ea kalafo ea holim'a metsi, ebe o e kopanya mochining oa ho luba o lebelo le tlase bakeng sa kalafo ea phetoho.Mokhoa oa ho fetola mokhoa oa metsi ke ho emisa magnesium hydroxide ka metsing kapa li-solvents tse ling, ka ho toba ho eketsa moemeli oa phekolo ea holim'a metsi kapa dispersant, le ho e fetola tlas'a ho sisinyeha.Mekhoa ena e 'meli e na le melemo le mathata a eona' me e hloka ho khethoa ho latela maemo a itseng.Ntle le mokhoa oa ho fetola holim'a metsi, mokhoa oa ho hloekisa o ka boela oa sebelisoa ho silakanya phofo ea magnesium hydroxide ho ea boemong ba nanometer, ho eketsa sebaka sa eona sa ho kopana le matrix a polymer, ho matlafatsa kamano ea eona le polymer, 'me ka hona ho ntlafatsa phello ea eona ea ho thibela mollo.
