Nrog rau kev cai lij choj ib puag ncig uas nruj zuj zus thiab kev paub txog kev nyab xeeb ntawm cov neeg siv khoom, cov thev naus laus zis polypropylene uas tsis muaj halogen tau dhau los ua qhov kev xaiv tseem ceeb rau kev sib npaug ntawm kev ua tau zoo ntawm cov khoom siv nrog kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Cov tshuaj halogenated flame retardants ib txwm tsim cov pa phem thiab corrosive thaum lub sijhawm combustion, thaum cov tshuaj halogen-free V0 flame retardants, nrog rau lawv cov khoom zoo rau ib puag ncig thiab cov peev xwm ua haujlwm zoo flame-retardant, ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam.
01 Lub hauv paus thev naus laus zis: Txoj cai ua haujlwm thiab hom halogen-free V0 nplaim taws retardant
Lub tshuab tseem ceeb ntawm cov tshuaj tua hluav taws V0 uas tsis muaj halogen yog lawv lub tshuab tua hluav taws tshwj xeeb. Thaum raug rau qhov kub siab, cov tshuaj tua hluav taws no tsim ib txheej ua npuas ncauj uas sib npaug thiab tuab rau ntawm qhov chaw ntawm cov khoom. Cov txheej ua npuas ncauj no tiv thaiv tau cua sov thiab oxygen, thiab tiv thaiv kev tsim pa luam yeeb, yog li ua tiav qib V-0 uas tiv thaiv hluav taws.
Cov tshuaj tiv thaiv nplaim taws Nitrogen-intumescent yog cov txheej txheem feem ntausiv phosphorus thiab nitrogen ua lub hauv paus tseem ceebhluav taws kub hnyiabcov ntsiab lus, ntxiv kwv yees li 24% -26% rau polypropylene txaus kom ua tiav tus qauv UL94 V-0 rau cov qauv 1.6 hli. Hom nplaim taws no yog tus cwj pwm los ntawm cov pa luam yeeb tsawg, tsis muaj tshuaj lom, thiab tsis ua rau ib puag ncig puas tsuaj, ua raws li EU RoHS cov lus qhia ib puag ncig thiab cov cai hauv tsev.
02 Cov chaw siv: Txij li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob mus rau cov khoom siv tsheb
Cov ntaub ntawv PP uas tsis muaj halogen V0 uas tiv taus hluav taws tau siv dav hauv ntau yam lag luam, nrog rau cov ntawv thov tseem ceeb suav nrog:
Hauv kev lag luam hluav taws xob thiab khoom siv hluav taws xob, cov tshuaj tiv thaiv hluav taws no siv dav rau kev siv tiv thaiv hluav taws hauv ntau lub tsev thiab cov khoom siv, xws li lub lauj kaub ua mov, lub lauj kaub hluav taws xob, lub thawv muab dej, thiab lub tub yees thiab lub tshuab ntxhua khaub ncaws.
Hauv kev lag luam tsheb, cov tshuaj tiv thaiv hluav taws V0 uas tsis muaj halogen yog siv rau hauv cov khoom siv cua txias hauv tsheb, cov consoles nruab nrab, thiab lwm yam khoom.
Hauv kev lag luam khoom siv hauv tsev, halogen-free flame-retardant PP yog siv rau hauv cov khoom xws li daim ntawv thiab cov laug cam.
03 Cov Ntsiab Lus Mob: Kev Sib Haum Xeeb, Kev Ruaj Ntseg Thermal, thiab Kev Ua Haujlwm
Txawm hais tias muaj ntau qhov zoo ntawm halogen-free V0 flame-retardant PP, tseem muaj ntau yam teeb meem kev siv tshuab tseem nyob hauv kev siv tiag tiag:
Kev sib raug zoo tsis zoo yog qhov teeb meem tseem ceeb. Nojammonium polyphosphate (APP)Piv txwv li, ib qho uas feem ntau siv halogen-free flame retardant, nws lub zog polarity ua rau tsis sib haum nrog cov polypropylene uas tsis yog polar, yooj yim cuam tshuam rau cov khoom siv thaum ntxiv rau hauv ntau ntau.
Kev ruaj khov thermal tsis txaus yog lwm qhov teeb meem tseem ceeb. APP yog ib hom polymer dawb uas tsis tiv taus cua sov. Nyob rau hauv cov xwm txheej ua haujlwm kub siab, nws dhau los ua pyrolysis, lwj mus ua cov tshuaj xws li ammonium phosphate, metaphosphoric acid, ammonia, thiab dej pa. Cov khoom lwj no, xws li metaphosphoric acid, uas tseem nyob hauv cov resin yuav los nag thaum lub sijhawm molding, lo rau ntawm phab ntsa pwm lossis ntsia hlau, cuam tshuam loj heev rau cov khoom zoo li cas thiab kev ua haujlwm zoo.
Kev nqus dej noo thiab kev tsiv teb tsaws chaw kuj yog teeb meem tseem ceeb. APP muaj hydrophilicity muaj zog, yooj yim nqus cov dej noo los ntawm huab cua, uas tom qab ntawd tsiv mus rau qhov chaw ntawm cov khoom, ua rau poob. Qhov no tsis tsuas yog cuam tshuam rau qhov ruaj khov ntawm cov khoom hluav taws kub tab sis kuj tseem yuav ua rau muaj qhov tsis zoo ntawm cov khoom.
Ntxiv ntau dhaukuj yog ib qho teeb meem uas PP tsis muaj halogen-free flame-retardant ntsib. Piv nrog rau cov tshuaj halogenated flame retardants ib txwm muaj, cov tshuab tsis muaj halogen feem ntau xav tau ntau dua ntxiv kom ua tiav tus qauv V-0, uas ua rau muaj kev cov nyom rau cov khoom siv kho tshuab thiab kev tswj tus nqi.
04 Cov Kev Dais Teeb Meem thiab Cov Lus Qhia Txog Kev Loj Hlob Yav Tom Ntej
Ntsib cov teeb meem kev siv tshuab hauv cov ntawv thov PP uas tsis muaj halogen V0 nplaim taws, kev lag luam tau tsim ntau txoj kev daws teeb meem zoo:
-Kev kho qhov chaw thiab kev ua kom zoo dua ntawm cov mis yog cov hauv kev zoo los txhim kho kev sib raug zoo.
- Kev tswj hwm cov txheej txheem zoo tshaj plaws kuj tseem ceeb heev.
-Kev tsim cov tshuab tiv thaiv hluav taws tshiab yog qhov kev daws teeb meem tseem ceeb.
