I-Premium Ammonium Polyphosphate (APP): Izinto ezisetyenziswa kakhulu zekhemikhali ezisebenza ngeendlela ezininzi
Iimpawu eziPhambili kunye neempawu eziPhambili
Ukwakhiwa kweekhemikhali: I-APP ine-phosphorus engama-30% - 32% kunye ne-nitrogen engama-14% - 16%. Le ndibaniselwano ye-nitrogen-phosphorus iyenza ibaluleke kakhulu kwiindlela ezininzi, njengokubonelela ngezondlo ezibalulekileyo ekukhuleni kwezityalo kwizichumisi kunye nokufezekisa ukulibaziseka komlilo okusebenzayo ngokusebenzisa isiphumo sokusebenzisana kwe-phosphorus kunye ne-nitrogen kwiimeko zokulibaziseka komlilo.
Uzinzo lobushushu: Ngobushushu bokubola kobushushu obuyi-≥280°C, i-APP ihlala izinzile kwiindawo ezinobushushu obuphezulu. Le propati iyenza ifaneleke ukuvelisa iimveliso ezimelana nobushushu ezifana neeplastiki zobunjineli kunye neengubo ezingatshiyo ezisetyenziswa kwiimeko ezinobushushu obuphezulu.
Ifomu Yomzimba kunye Nokunyibilika: Iqondo lokwenziwa kwepolymerization lichaphazela ukunyibilika kwamanzi ayo. Xa i-n ingama-10 - 20, iyanyibilika emanzini; xa ingama-20, ayinyibiliki kakuhle. Iimveliso ze-polymer eziqhelekileyo (n>1000) azinyibiliki emanzini, zikho njengemibhobho emhlophe egeleza amanzi enobunzima obumalunga ne-0.7g/cm³, ubuninzi obumalunga ne-1.9g/cm³, i-pH kuluhlu olufutshane nolungathathi cala lwe-5.5 - 7.0, kunye nomxholo wokufuma we-≤0.25%.
IiNdawo eziPhambili zeSicelo
Intsimi Ethintela Ilangatye: Undoqo weHalogen - Izinto Ezithintela Ilangatye Ezingenamalangatye
I-APP yinto ethintela ilangatye esekwe kwi-halogen-free phosphorus, isiya isanda kwimkhwa yophuhliso lwezinto ezinobuhlobo nokusingqongileyo kunye nezinto ezithintela ilangatye ezinobungozi obuphantsi.
Iingubo Ezingatshiyo Ezingenamlilo Ezingaphakathi: Zisetyenziswa kakhulu kwiindlela zokwambathisa umlilo ezingaphakathi. Xa kutsha umlilo, i-APP iyabola xa ifudunyezwa, nto leyo ebangela ukuba i-coating yande kwaye yenze i-carbonaceous layer ene-foam foam. Le carbonaceous layer isebenza njengomqobo wokuthintela ubushushu, ithintela ngempumelelo ukudluliselwa kobushushu kwi-substrate kwaye inciphise ukunyuka kobushushu be-substrate, ngaloo ndlela ifumana ixesha lokuphuma kwabasebenzi kunye nokulwa nomlilo. Kwiimeko ezineemfuno eziphezulu kakhulu zokhuseleko lomlilo, ezifana nezakhiwo eziphakamileyo, izixhobo zamandla, kunye neenqanawa, ezi ngubo zidlala indima ebalulekileyo yokukhusela umlilo ngenxa yomsebenzi we-APP.
Iiplastiki kunye neemveliso zerabha: Ukongeza i-APP kwiiplastiki ze-thermoplastic ezifana ne-polyethylene kunye ne-polypropylene, kunye neemveliso zerabha, kunokuphucula kakhulu ukulibaziseka komlilo kwezinto. Kwiibhokisi zeplastiki zeemveliso ze-elektroniki nezombane, iindawo zeplastiki zangaphakathi zeemoto, kunye nerabha yokukhusela iingcingo kunye neentambo, i-APP ithintela ukuqhubeka kokutsha ngokwenza umaleko wekhabhoni ozinzileyo kumphezulu wezinto ngokusebenzisa indlela yokulibaziseka komlilo yesigaba esidityanisiweyo, ukuhlangabezana nemigangatho engqongqo yokulibaziseka komlilo yamashishini afanelekileyo kunye nokuqinisekisa ukhuseleko lwemveliso esetyenziswayo.
Iifayibha kunye namaLaphu: Zisetyenziselwa unyango lwefayibha kunye namalaphu oluthintela ilangabi. Emva konyango nge-APP, iifayibha kunye namalaphu akulula ukuwatshisa xa udibana nomthombo womlilo, nto leyo enciphisa umngcipheko wokusasazeka komlilo kwindawo enkulu okubangelwa ziilaphu emlilweni. Ihlala isetyenziswa kwiimveliso ezifana namalaphu empahla yokusebenza, amakhethini, kunye neekhaphethi ukuphucula ukhuseleko lomlilo kwiindawo zikawonke-wonke kunye namalaphu asekhaya.
Ishishini lezichumisi: Isithwali sezondlo esisebenzayo nesisebenzayo
Izinto Ezibalulekileyo Ezisetyenziswa Emanzini - Izichumisi Ezinyibilikayo: Zizinto ezibalulekileyo ekuphuhlisweni kwezichumisi ezinyibilikayo emanzini. Ingakumbi i-APP ye-polymer ephantsi, enobunyibiliko obuhle, ukuhambelana kwayo, kunye nobushushu obuphantsi bekristale, iba yinxalenye efanelekileyo yezichumisi ezingamanzi. Ingasetyenziselwa ukulungiselela izichumisi ezingamanzi ezinomxholo ophezulu we-phosphorus, kwaye i-pH yayo ephantse ingathathi cala yenza ukuba ikhuseleke kakhulu kwizityalo. Inganciphisa ii-ion zesinyithi ezifana ne-calcium, i-magnesium, i-iron, kunye ne-zinc, ithintela ezi i-ion ukuba zenze iiprecipitates kwisisombululo sesichumisi kwaye iphucule uzinzo lwesichumisi. Kwangaxeshanye, iphucula ukuhamba kwe-phosphorus kunye nezinto ezilandelelanayo emhlabeni, izenze zifunxwe lula kwaye zisetyenziswe zizityalo, iqonda ukusebenza okuninzi kwezichumisi kwaye ihlangabezana neemfuno zesondlo zezityalo kumanqanaba ahlukeneyo okukhula.
Iimpawu Zokukhulula Okucothayo Okusebenzayo: Emhlabeni, i-APP inyibilika kancinci kancinci ibe yi-orthophosphate, ikhupha izinto ze-phosphorus kancinci kancinci ukuze ibonelele ngesondlo sexesha elide kwizityalo. Xa kuthelekiswa nezichumisi ze-phosphate eziqhelekileyo, inexesha elide lokusebenza kakuhle kwesichumisi, inciphisa inani lezichumisi, iphucula izinga lokusetyenziswa kwezichumisi, inciphisa iindleko zemveliso yezolimo, kwaye kwangaxeshanye inciphisa ukulahleka kwezondlo zomhlaba kunye nongcoliseko lokusingqongileyo olubangelwa kukuchumisa rhoqo, ngokuhambelana nombono wophuhliso oluzinzileyo lwezolimo.
Ezinye izicelo zemizi-mveliso
Intsimi Yonyango Lwamanzi: Njengearhente yonyango lwamanzi, i-APP inokunxibelelana nee-ion zobunzima (ezifana nee-ion ze-calcium kunye ne-magnesium) emanzini ukuze zenze ii-complexes ezinganyibilikiyo, zinciphise ubunzima bamanzi kwaye zithintele ukukhuhlana kwimibhobho nakwizixhobo. Ingenza nefilimu ekhuselayo kumphezulu wemibhobho yesinyithi, idlala indima yokuthintela ukugqwala kwaye icinezele ukugqwala kwesinyithi, ngaloo ndlela yolula ubomi benkonzo yemibhobho nezixhobo. Isetyenziswa kakhulu kwiinkqubo zamanzi ezijikelezayo zoshishino, unyango lwamanzi ebhoyila, nakwezinye iimeko.
Izithako zokugquma: Kwinkqubo yokugquma, i-APP ingasebenza njengesithinteli-zinambuzane, isibulali-ntsholongwane, kunye nesicoci. Ingaphucula ukunamathela kwengubo kwi-substrate, yenze ukuba ingubo inamathele ngokuqinileyo kumphezulu wento. Ingaphucula amandla engubo, iphucule ukuguguleka kunye nokukrweleka kwengubo. Ingaphucula nokuthamba kunye nokulingana kwengubo, yenze umphezulu wengubo ube mpuluswa kwaye ufane ngakumbi, kwaye iphucule umgangatho kunye nefuthe lokuhombisa lengubo.
