Thermal Decomposition ntawm Hexagonal Magnesium Hydroxide: Yuav Ua Li Cas Thaum Nws Kub?
Nyob rau hauv kev kub ntxhov, Mg(OH)₂ hloov nyob rau hauv ib txoj kev uas ua raws li zoo -paub cov tshuaj tiv thaiv kab mob uas siv los ntawm technical engineers los tsim hluav taws kev ruaj ntseg systems. Paub txog cov kev ua haujlwm no pab piav qhia tias vim li cas xaiv cov khoom siv raug cuam tshuam rau ob qho tib si nws tau ua tiav zoo npaum li cas thiab kev nyab xeeb ntawm cov khoom kawg.
Chemistry Qab Thermal Decomposition
Thaum tshav kub kub, magnesium hydroxide tawg rau hauv magnesium oxide thiab dej. Cov txheej txheem no yuav siv li ntawm 1450 J / g ntawm cov cua sov, uas tsim kom muaj cov dab dej kub loj uas ua rau qhov kub thiab txias ntawm cov khoom nyob ze. 31% ntawm cov khoom qub uas tau tso tawm raws li cov dej vapor dilutes cov nplaim hluav taws kub hauv thaj chaw nplaim taws, txo qis cov pa oxygen hauv qab qhov xav tau los ua kom hluav taws mus. Cov khoom seem ntawm magnesium oxide tsim cov txheej txheem porous ceramic uas tiv thaiv cov khoom siv los ntawm cov hluav taws xob hluav taws xob thiab nres cov nplaim taws los ntawm kev sib kis. Cov kev ua hauj lwm ua ke piav qhia yog vim li cas Hexagonal Magnesium Hydroxide tuaj yeem tau txais UL94 V-0 kev ntsuam xyuas hauv cov khoom sib xyaw polymer ntawm qhov chaw thauj khoom ntawm 55 thiab 65%, thaum cov ntxhia tsis tu ncua yuav tsum yog 60 mus rau 70%.
Temperature Kub thiab Industrial Relvance
Cov theem kub sib txawv tshwm sim nyob rau hauv decomposition. Cov khoom siv tsis ua ntau ntawm chav tsev kub thiab 280 degree, uas yog ib qho tseem ceeb rau kev ua hauj lwm nrog plastics xws li polyamide los yog polypropylene uas xav tau melt kub ntawm 220 thiab 260 degree. Qhov tseeb tias qhov decomposition pib nyob ib ncig ntawm 300℃muab txaus ntawm lub cushion kev nyab xeeb rau kev ua haujlwm sib xyaw ua ke.
Qhov ceev tshaj plaws ntawm decomposition tshwm sim ntawm 340℃thiab 380 degree, uas yog raws nraim qhov kub ntau yam uas tua hluav taws hauv hlau lossis vaj huam sib luag siv kev paub. Ntawm 450 degree, kev hloov mus rau MgO ua tiav, tawm hauv qab lub thermally ruaj khov oxide qauv uas tseem tiv thaiv lub cev. Cov neeg tsim hluav taws xob hluav taws xob hloov kho lawv cov kev sib xyaw ua ke raws li cov kev hloov pauv no kom pom qhov sib npaug zoo ntawm kev ua haujlwm yooj yim thiab kev nyab xeeb hluav taws.
Cov kev cuam tshuam rau kev tsim khoom
Cov neeg tsim khoom siv hluav taws xob uas siv ntxaib- ntsia hlau extruders khaws lub qhov muag ntawm qhov kub thiab txias ntawm cov thoob kom qhov sib xws ntawm cov khoom thiab xyuas kom muaj kev tawg txaus txaus. Hexagonal Magnesium Hydroxide hom muaj thermally ruaj khov, uas txhais tau hais tias lawv tuaj yeem tswj cov ntsia hlau siab dua thiab cov khoom siv ntau dua yam tsis tso dej tawm sai sai, uas tuaj yeem ua rau muaj qhov tsis zoo lossis qhov. Cov neeg tsim khoom ntawm aluminium composite panels kuj tau txais txiaj ntsig thaum cov ntaub ntawv tseem ceeb tau kub txog 180-200℃thiab khaws cia nyob rau hauv qhov siab tas li thaum lub sijhawm kub nias. Lub qhov rais ua haujlwm uas tsis tso cai rau kev tawg cia cov resin teeb tsa tag nrho thiab daim ntawv adhesion zoo tshaj plaws ua ntej cov nplaim hluav taws kub hnyiab tau qhib.
Muab piv rau Hexagonal Magnesium Hydroxide rau Lwm Cov Ntawv thiab Fillers
Kev xaiv cov ntaub ntawv suav nrog kev sib piv ntau cov kev xaiv raws li cov qauv kev ua tau zoo uas tshwj xeeb rau daim ntawv thov. Txhawm rau kom tau txais cov nqi hauv daim ntawv qhia zoo tshaj plaws yam tsis tau txo qis cov qauv kev nyab xeeb, pab pawg kws tshaj lij saib cov khoom xws li cov khoom cua sov, cov khoom siv hluav taws xob, kev coj ua, thiab cov nqi.
Hexagonal piv rau Daim Ntawv -Form Magnesium Hydroxide
Daim ntawv- cov qauv qauv muaj qhov sib txawv ntawm qhov sib txawv thiab cov yam ntxwv saum npoo uas cuam tshuam rau lawv ua haujlwm zoo li cas nrog cov polymers. Hexagonal platelets feem ntau ntim tau zoo dua, cia cov ntshav ntau dhau los nrog cov teeb meem qis dua. Vim tias lawv cov qauv ua haujlwm ntau dua,Hexagonal Magnesium Hydroxidecrystals tso dej vapor los ntawm kev sib txawv ntau dua thaum lawv tawg ntawm qhov kub thiab txias.
Vim hais tias ntawm qhov kev tso tawm cov qauv no, tsis muaj qhov nrawm nrawm uas tuaj yeem ua rau tuab - ntu molded qhov chaw kom hlwv rau ntawm qhov chaw. Hauv qee qhov kev siv barrier, daim ntawv duab yuav zoo dua vim tias cov lamellar kev sib raug zoo ua rau cov cua sov ua haujlwm zoo dua. Tab sis rau cov nplaim hluav taws xob dav dav hauv cov xov hlau thiab cov ntsaws, cov duab hexagonal ua haujlwm zoo dua thoob plaws ntau yam kev ua haujlwm.
Kev sib piv nrog lwm cov nplaim hluav taws retardant Fillers
Los ntawm ntau, txhuas trihydrate yog qhov tseem ceeb tshaj plaws halogen -dawb nplaim hluav taws. Txawm li cas los xij, nws tawg nyob ib ncig ntawm 200 degree, ua rau nws tsis zoo rau cov khoom kub siab dua -. Vim li no, ATH tsuas yog siv tau rau PVC thiab qee qhov kev siv copolymer. Basic magnesium carbonate tawg me ntsis txias dua magnesium hydroxide thiab muab CO2 tawm ntawm dej vapor. Nws muaj cov khoom sib txawv rau kev tso pa tawm tab sis tsis zoo ntawm kev nqus cua sov ib chav tsev.

Peb cov khoom yog tsim los siv cov brine niaj hnub -raws li tshuaj synthesis thiab kev tswj kom zoo uas ua tau raws li cov qauv thoob ntiaj teb. Lawv ua tau raws li cov kev cai nruj ntawm cov tuam txhab thoob plaws 33 lub teb chaws uas ua kom tsawg - pa taws halogen- cov cables dawb, aluminium composite panels, thiab engineering plastics compounds. Qhov tsawg kawg nkaus 99.5% Mg (OH)₂ cov ntsiab lus, tswj 4-6 m² / g thaj chaw tshwj xeeb, thiab cov khoom tsis zoo uas tsis tshua muaj muab rau koj cov khoom ua tau zoo raws li lawv xav tau.
Peb paub tias nws nyuaj npaum li cas los nrhiav qhov chaw ntseeg tau thiab xyuas kom meej tias txhua pawg yog tib yam. Los ntawm kev yuav ncaj qha los ntawm cov nroj tsuag, peb zam cov cim los ntawm cov neeg nruab nrab, thiab peb cov peev txheej tsim tau ua kom muaj kev ruaj khov txawm tias thaum lub lag luam hloov pauv. Cov pab pawg kws tshaj lij tuaj yeem nkag mus rau cov lus qhia ntxaws txog cov khoom lag luam, cov lus qhia txog kev siv cov khoom, thiab kev pabcuam sai rau cov lus nug txog kev txhim kho. Koj tuaj yeem tham nrog peb cov kws tshaj lij txog koj qhov xav tau Hexagonal Magnesium Hydroxide los ntawm emailinfo@henghaopigment.com. Koj tseem tuaj yeem nug cov qauv los ntsuas lossis tau txais cov nqe lus pheej yig uas yuav pab tau koj cov khoom lag luam zoo.
