Qhov zoo thiab qhov tsis zoo ntawm Inorganic Flame Retardants

Kev siv ntau ntawm cov ntaub ntawv polymer tau nrawm rau kev loj hlob ntawm kev lag luam nplaim hluav taws. Cov nplaim hluav taws kub hnyiab yog ib pawg tseem ceeb ntawm cov khoom siv ntxiv hauv lub neej niaj hnub no, tiv thaiv hluav taws zoo, tswj kev sib kis, thiab ua rau muaj txiaj ntsig zoo rau kev nyab xeeb thiab kev ua neej nyob txhua hnub. Cov ntaub ntawv kho nrog cov nplaim hluav taws tuaj yeem tiv thaiv kom tsis txhob muaj hluav taws kub, ua kom qeeb, lossis nres kev sib kis ntawm cov nplaim taws thaum raug hluav taws kub sab nraud, yog li ua tiav cov nplaim hluav taws. Muaj ntau ntau hom nplaim retardants, thiab txhua yam muaj ob sab - nplaim retardants kuj muaj lawv qhov zoo thiab qhov tsis zoo. Hauv qab no yog kev soj ntsuam ntawm qhov zoo thiab qhov tsis zoo ntawm ntau yam inorganic nplaim retardants.

Disadvantages ntawm Inorganic nplaim retardants:
Lub ntsiab drawback ntawm inorganic nplaim taws retardants yog lawv siab npaum li cas (feem ntau tshaj 50%) nyob rau hauv cov ntaub ntawv polymer, uas tuaj yeem ua rau tsis zoo rau kev ua haujlwm thiab lub cev. Cov kev daws teeb meem suav nrog kev kho saum npoo nrog cov khoom sib txuas, ultrafine particle refinement, thiab nanotechnology, uas sawv cev rau cov lus qhia tseem ceeb rau kev txhim kho yav tom ntej.

Qhov zoo ntawm Inorganic nplaim retardants:

1. Aluminium Hydroxide (ATH): Ua ke cov nplaim hluav taws kub, tiv thaiv cov pa luam yeeb, thiab ua haujlwm ua ib qho. Nws yog non-toxic, non-corrosive, ruaj khov heev, tsis tsim cov pa roj carbon monoxide nyob rau hauv qhov kub thiab txias, yog tus nqi-zoo, thiab dav muaj.
2. Magnesium Hydroxide (MTH): Decomposes ntawm 340-490 ° C, muab cov thermal stability zoo heev thiab cov nplaim hluav taws kub hnyiab thiab cov pa taws tua hluav taws. Nws yog qhov tshwj xeeb tshaj yog tsim rau kev ua cov yas polyolefin ntawm qhov kub thiab txias.
3. Liab Phosphorus: Muab cov pa luam yeeb, tsis muaj tshuaj lom, thiab ua kom cov nplaim hluav taws muaj zog heev. Txawm li cas los xij, phosphorus liab yog nquag oxidation nyob rau hauv huab cua, tej zaum yuav spontaneously combust, thiab maj mam tso tshuaj lom phosphine gas nyob rau lub sij hawm ntev cia. Nws compatibility nrog cov ntaub ntawv polymer tsis zoo, nrog microencapsulation yog thawj cov tshuaj.
4. Ammonium Polyphosphate (APP): Kuj tseem muaj cov nplaim hluav taws kub hnyiab, nws muaj cov nitrogen thiab phosphorus siab, pom zoo thermal stability, thiab yog ze li ntawm nruab nrab hauv cov muaj pes tsawg leeg. Nws tuaj yeem sib xyaw nrog lwm cov nplaim hluav taws kub, muaj qhov zoo dispersibility, thiab tsis muaj tshuaj lom, ua kom muaj kev nyab xeeb. Txawm li cas los xij, thaum lub polymerization degree ntawm APP txo qis, nws ua me ntsis dej-soluble. Tsis tas li ntawd, APP yog me ntsis acidic thiab nquag nqus dej noo nyob rau hauv qhov chaw ntub dej.
