Uburyo bwo gukumira umuriro wa Ammonium Polyphosphate n'akamaro kawo

Uburyo n'akamaro k'urumuri rwa Ammonium Polyphosphate

Indabyo zigabanya umuriro za Ammonium polyphosphate (APP) zishobora gushyirwa mu byiciro bitatu hashingiwe ku rugero rwa polymerization yazo: polymerization nke, hagati, n'iy'ikirenga. Uko polymerization irushaho kuba nyinshi, niko gushonga kw'amazi kugabanuka, naho gushonga kw'amazi kugabanuka. Mu miterere yayo, ishobora kugabanywamo imiterere ya crystalline na amorphous, aho crystalline APP iba ​​umunyu muremure udashonga mu mazi. Formula rusange ya APP ni (NH₄)ₙ₊₂PₙO₃ₙ₊₁. Iyo n iri hagati ya 10 na 20, iba ishonga mu mazi; iyo n irenze 20, iba idashobora gushonga. APP ntabwo ari uburozi, nta mpumuro, ntabwo yangiza, kandi igaragaza hygroscopicity nke, ubushyuhe bwinshi buhamye, kandi ifite imikorere myiza nk'irinda umuriro utagira halogen.

Uburyo bwo gukumira umuriro bwa APP:
Iyo ishyushye, APP irabora igakora aside poly-/metaphosphoric, ituma amazi agabanuka kandi ikagira karubone ku buso bw'ibintu bikomoka ku bimera. Irakura iyo ishyushye, igakora urwego rwo kurinda ibintu rutandukanya ogisijeni n'umwuka, bityo bigatuma umuriro udakomeza gutwika. Byongeye kandi, gushonga k'ubushyuhe bwa APP bisohora imyuka idashya nka CO₂ na NH₃, bigabanya ubwinshi bwa ogisijeni mu kirere, bigatuma ogisijeni igabanuka. Ibi bipimo bituma umwotsi ugabanuka, nta myuka ihumanya ikorwa, kandi ikayizima ubwayo. Ikigaragara ni uko kutagira imyuka ihumanya atari ukurengera ibidukikije gusa ahubwo ni ingenzi cyane ku mutekano w'ubuzima—imibare igaragaza ko hejuru ya 80% by'impfu mu bihe bikomeye by'inkongi z'umuriro ziterwa n'imyuka ihumanya ituruka kuri pulasitiki itwikwa, ibikoresho by'ikoranabuhanga, n'ibindi bikoresho, aho guterwa n'umuriro ubwawo.

Uruganda rwa APP Flame Retardant:
Taifeng Flame Retardant ikoresha ikoranabuhanga rya microencapsulation rigezweho ku rwego mpuzamahanga kugira ngo ikore APP ifite polymerization nyinshi ifite fosifore na azote nyinshi. Iyi poroduwa ifite ubushyuhe bwiza, amazi adashobora gushonga neza, pH hafi ya neutral, hamwe n'ubushobozi bwo kudashonga neza. Ni ifu y'umweru ikomeye, ntabwo ihinduka hygroscopic, ntishobora gushya, kandi ifite uburemere bwinshi bwa molekile (n > 1200), idahinduka, kandi irwanya ikirere. Ikoreshwa cyane mu gutwikira hakoreshejwe amazi, gutwikira imyenda, ndetse no mu gutwikira thermoplastics irinda umuriro. Iyi poroduwa ikorerwa mu ruhu ikorerwa ku buso kugira ngo irusheho guhuza neza, irusheho kurwanya ubushuhe, pH ya alkaline, ndetse no kugabanuka k'ubushuhe mu mazi.
