Cov txiaj ntsig ntawm Magnesium Hydroxide Flame Retardant

Cov txiaj ntsig ntawm Magnesium Hydroxide Flame Retardant

Magnesium hydroxide yog ib hom tshuaj uas siv los ua kom nplaim taws kub. Thaum raug cua sov, nws yuav lwj thiab tso cov dej tawm, thiab nqus tau cov cua sov latent ntau heev. Qhov no ua rau qhov kub ntawm cov khoom sib xyaw hauv nplaim taws txo qis, tiv thaiv kev lwj ntawm cov polymer thiab ua kom cov pa roj uas yooj yim hlawv tawm txias. Magnesium hydroxide yog ib yam tshuaj uas siv los ua kom nplaim taws kub rau cov khoom sib xyaw ua los ntawm polymer. Ib yam li txhuas hydroxide, nws ua haujlwm los ntawm kev nqus cua sov los ntawm kev lwj ntawm cov khoom thiab tso dej tawm, ua rau nws tsis muaj tshuaj lom, tsis muaj pa luam yeeb, thiab zoo rau ib puag ncig, vim tias cov magnesium oxide uas tshwm sim ruaj khov thiab tsis ua rau muaj kuab paug thib ob.

Txawm li cas los xij, piv rau cov tshuaj tua hluav taws uas muaj halogen, kev ua tiav tib yam kev ua haujlwm tua hluav taws yuav tsum muaj qhov sib piv ntawm ntau dua 50%. Vim tias magnesium hydroxide yog inorganic, nws qhov chaw tsis sib haum xeeb nrog cov polymer substrates. Qhov sib piv siab ntawm kev sau, yam tsis muaj kev hloov kho qhov chaw, yuav ua rau cov khoom siv kho tshuab ntawm cov khoom sib xyaw puas tsuaj. Yog li ntawd, kev hloov kho qhov chaw yog qhov tsim nyog los txhim kho nws qhov sib haum xeeb nrog cov polymer substrates, kom ntseeg tau tias cov khoom siv kho tshuab ntawm cov khoom siv puv tsis raug cuam tshuam - lossis txawm tias txhim kho hauv qee qhov.

Thoob plaws hauv cov txheej txheem tiv thaiv hluav taws, magnesium hydroxide tsis tsim cov tshuaj lom. Ntxiv mus, nws cov khoom lwj tuaj yeem nqus tau ntau cov pa roj lom thiab cov pa luam yeeb uas tsim los ntawm kev hlawv roj hmab, yas, thiab lwm yam polymers. Cov magnesium oxide nquag nqus cov khoom seem uas tsis tau hlawv tag, tua cov nplaim taws sai sai thaum tshem tawm cov pa luam yeeb thiab tiv thaiv cov yaj ntws. Nws yog cov tshuaj tiv thaiv hluav taws inorganic uas tsis muaj kuab paug rau ib puag ncig.

Tam sim no, txhuas hydroxide siv dav dua hauv Suav teb. Txawm li cas los xij, thaum qhov kub ntawm cov polymer ua haujlwm nce ntxiv, txhuas hydroxide feem ntau yuav lwj, txo nws cov hluav taws kub. Piv txwv li, magnesium hydroxide muaj cov txiaj ntsig hauv qab no:

1. Kub Dua Thaum Tshav Kub Dua - Magnesium hydroxide lwj ntawm 340 ° C, uas yog 100 ° C siab dua li aluminium hydroxide. Qhov no tso cai rau qhov kub siab dua rau kev ua cov yas, txhim kho kev ua haujlwm extrusion, txhim kho kev ua yas, txo lub sijhawm molding, thiab ua kom muaj qhov ci ntsa iab nrog tsawg qhov tsis zoo thaum tswj lub zog tev tawv.
2. Qhov Loj Me Me & Kev Sib Haum Xeeb Zoo - Nws qhov kev faib tawm ntawm cov khoom me me ua kom muaj kev sib raug zoo dua nrog cov substrates, txo qhov cuam tshuam rau cov khoom siv kho tshuab ntawm cov khoom.
3. Kev Tsim Ib Qho Kev Tiv Thaiv - Tom qab lub sijhawm qhuav dej thaum lub sijhawm hlawv, cov magnesium oxide uas tshwm sim yog ib yam khoom muaj zog heev, tiv taus cua sov uas ua haujlwm ua ib qho kev tiv thaiv, cais cov nplaim taws thiab cov pa phem. Magnesium hydroxide kuj tseem ua rau cov pa acidic (SO₂, NOx, CO₂) tsis muaj zog uas tsim tawm thaum lub sijhawm hlawv yas.
4. Kev Ua Haujlwm Zoo Tshaj Plaws thiab Kev Tswj Pa Luam Yeeb - Nws muaj peev xwm tiv taus hluav taws thiab tswj pa luam yeeb thaum tsis txhuam cov khoom siv, yog li ua rau lub tshuab siv tau ntev dua.
5. Tus nqi tsim nyog - Magnesium hydroxide nplaim taws retardant yog ib nrab ntawm tus nqi ntawm txhuas hydroxide. Nws lub peev xwm ntim siab ua rau txo cov nqi tsim khoom.
