Qhov Tseem Ceeb ntawm Melamine-Coated Ammonium Polyphosphate (APP) hauv Flame Retardancy

Qhov Tseem Ceeb ntawm Melamine-Coated Ammonium Polyphosphate (APP) hauv Flame Retardancy

Kev hloov kho qhov chaw ntawm ammonium polyphosphate (APP) nrog melamine yog ib qho tseem ceeb los txhim kho nws qhov kev ua tau zoo, tshwj xeeb tshaj yog hauv cov ntawv thov tiv thaiv hluav taws. Hauv qab no yog cov txiaj ntsig tseem ceeb thiab cov txiaj ntsig kev siv tshuab ntawm txoj hauv kev txheej txheem no:

1. Kev Tiv Thaiv Dej Zoo Dua

• Qhov teeb meem:APP yog hygroscopic heev, ua rau clumping thiab kev ua haujlwm poob qis thaum lub sijhawm khaws cia thiab ua tiav.
• Kev daws teeb meem:Lub txheej melamine tsim cov hydrophobic barrier, txo cov dej noo nqus thiab txhim kho APP qhov ruaj khov thiab lub neej txee.

2. Kev Ruaj Ntseg Thermal Zoo Dua

• Kev Sib Tw:APP tej zaum yuav lwj ua ntej lub sijhawm thaum kub siab, ua rau nws cov nyhuv tiv thaiv hluav taws tsis muaj zog.
• Txoj Kev Tiv Thaiv:Cov khoom tiv taus kub ntawm melamine qeeb qeeb rau kev lwj ntawm APP, ua kom muaj kev tua hluav taws ntev dua thaum lub sijhawm ua haujlwm lossis thaum raug hluav taws thaum ntxov.

3. Kev Sib Tw Zoo Dua thiab Kev Sib Tshuam

• Kev Sib Tw Sib Xws ntawm Matrix:Kev sib raug zoo tsis zoo ntawm APP thiab polymer matrices (piv txwv li, plastics, roj hmab) feem ntau ua rau muaj kev sib kis tsis sib xws.
• Kev Hloov Kho Nto:Cov txheej melamine txhim kho kev sib txuas ntawm cov nplaim hluav taws, txhawb kev faib tawm sib npaug thiab ua kom muaj zog tiv thaiv hluav taws.

4. Kev cuam tshuam nplaim taws synergistic

• Kev sib koom ua ke ntawm Nitrogen-Phosphorus:Melamine (qhov chaw nitrogen) thiab APP (qhov chaw phosphorus) ua haujlwm ua ke los tsim ib txheej char ntom dua, rwb thaiv cua sov thiab oxygen tau zoo dua.
• Kev Tsim Char:Lub kaw lus coated tsim cov char residue ruaj khov thiab muaj zog dua, ua rau kev kub hnyiab qeeb.

5. Cov txiaj ntsig ntawm ib puag ncig thiab kev nyab xeeb

• Cov Pa Phem Txo:Lub txheej txheej txo qis APP qhov kev raug ncaj qha, txo qis kev tso tawm ntawm cov khoom tsis zoo (piv txwv li, ammonia) thaum lub sijhawm ua lossis hlawv.
• Kev Lom Zem Tsawg Dua:Kev kaw melamine yuav txo APP qhov cuam tshuam rau ib puag ncig, ua raws li cov cai nruj dua.

6. Kev Ua Haujlwm Zoo Dua

• Kev ntws tau:Cov khoom APP uas tau coated ua rau pom cov nplaim du dua, ua kom cov khoom ntws zoo dua rau kev sib tov thiab ua tiav yooj yim dua.
• Kev Tiv Thaiv Pluav Plua Plav:Cov txheej txheej no txo ​​cov hmoov av, ua kom muaj kev nyab xeeb hauv chaw ua haujlwm.

7. Daim Ntawv Thov Dav Dav

• Cov Khoom Siv Zoo Tshaj Plaws:APP hloov kho tshiab yog tsim rau cov ntawv thov uas xav tau kev siv zog ntau (piv txwv li, cov khoom siv hluav taws xob, cov khoom siv hauv tsheb) uas xav tau kev tiv taus huab cua/dej zoo dua.
• Cov Txheej Txheem Kub Siab:Qhov kev ruaj khov zoo dua tso cai rau kev siv hauv extrusion, txhaj tshuaj molding, thiab lwm txoj hauv kev kub siab.

Cov Kev Siv Tau Zoo

• Cov Khoom Siv Engineering:Ua kom cov nplaim taws tsis kam hauv nylon, polypropylene, thiab lwm yam, tsis muaj kev cuam tshuam rau cov khoom siv kho tshuab.
• Cov Txheej Txheem & Cov Ntaub:Ua kom cov xim thiab cov ntaub tiv taus hluav taws ruaj khov dua.
• Cov Khoom Siv Roj Teeb:Txo cov kev pheej hmoo ntawm kev lwj thaum siv ua cov khoom ntxiv uas tiv taus hluav taws hauv cov roj teeb lithium-ion.

Xaus lus

APP uas muaj melamine coated hloov pauv ntawm cov khoom siv hluav taws xob yooj yim mus rau hauv cov khoom siv ntau yam, daws cov teeb meem tseem ceeb xws li kev rhiab heev rau dej noo thiab kev tsis ruaj khov thaum ua kom muaj kev ua haujlwm ntawm cov hluav taws xob los ntawm kev sib koom ua ke. Txoj hauv kev no tsis yog tsuas yog ua kom zoo dua qub xwb tab sis kuj nthuav dav APP txoj kev siv hauv cov lag luam siab heev, ua rau nws yog qhov tseem ceeb hauv kev tsim cov hluav taws xob ua haujlwm.
