Amonium Polyphosphate Flame Retardant Mechanism hamwe nibyiza
Ammonium polyphosphate (APP) flame retardant irashobora gushyirwa mubwoko butatu bitewe nurwego rwayo rwa polymerisiyasi: hasi, hagati, na polymerisiyasi nyinshi. Urwego rwo hejuru rwa polymerisiyonike, niko amazi agabanuka, naho ubundi. Mu buryo bwubaka, irashobora kugabanywa muburyo bwa kristaline na amorphous, hamwe na kristaline APP ikaba umunyu muremure wumunyu-amazi adashonga. Inzira rusange ya APP ni (NH₄) ₙ₊₂PₙO₃ₙ₊₁. Iyo n iri hagati ya 10 na 20, iba ibora amazi; iyo n irenze 20, iba idashobora gukemuka. APP ntabwo ari uburozi, impumuro nziza, ntishobora kubora, kandi irerekana hygroscopique nkeya, ituze ryinshi ryumuriro, hamwe nibikorwa byiza nkumuriro wa halogene utagira umuriro.
Uburyo bwa Flame Retardant Mechanism ya APP:
Iyo ishyushye, APP ibora gukora aside poly- / metafosifike, itera umwuma hamwe na karubone hejuru yibikoresho kama. Iraguka iyo ishyushye, ikora urwego rukingira rutandukanya ibintu na ogisijeni, bityo bikagera ku gucana umuriro. Byongeye kandi, kubora k'ubushyuhe bwa APP kurekura imyuka idashya nka CO₂ na NH₃, bigabanya umwuka wa ogisijeni mu kirere, bikagabanya itangwa rya ogisijeni. Ibi biranga bivamo imyotsi mike, nta musaruro wa gazi ufite ubumara, hamwe no kuzimya. Ikigaragara ni uko kutagira imyuka y’ubumara bitangiza ibidukikije gusa ahubwo binagira ingaruka ku mutekano w’ubuzima - imibare yerekana ko abantu barenga 80% bahitanwa n’impanuka zikomeye z’umuriro biterwa n’umwotsi w’ubumara uturuka ku gutwika plastiki, ibikoresho bya elegitoroniki, n’ibindi bikoresho, aho kuba umuriro ubwayo.
Uwakoze APP Flame Retardant:
Taifeng Flame Retardant ikoresha tekinoroji ya microencapsulation yateye imbere ku rwego mpuzamahanga kugirango ikore APP-polymerisation yo mu rwego rwo hejuru hamwe na fosifore nyinshi hamwe na azote. Igicuruzwa kirimo ubushyuhe buhebuje, ubushyuhe buke bwamazi, hafi ya pH itabogamye, hamwe nubushobozi buke bwa flame-retardant. Ni ifu yera ikomeye, idafite hygroscopique, idacanwa, kandi irerekana uburemere buke bwa molekile (n> 1200), ituze, hamwe n’imihindagurikire y’ikirere. Irakoreshwa cyane mumazi ashingiye kumuriro, yambara imyenda, kandi nkigice cyingenzi muri intumecent flame-retardant thermoplastique. Igicuruzwa gikubiyemo ibintu bivura hejuru kugirango habeho ubwuzuzanye, kongera imbaraga zo kurwanya ubushuhe, alkaline pH, ndetse no kugabanuka kwamazi.
