Izinto eziluncedo kunye nezingeloncedo kwi-Inorganic Flame Retardants

Ukusetyenziswa ngokubanzi kwezixhobo zepolymer kuye kwakhawulezisa ukukhula kweshishini lokubuyiswa komlilo. Iiretardants zomlilo ziludidi olubaluleke kakhulu lwezongezo ezibonakalayo kuluntu lwanamhlanje, ngokufanelekileyo ukuthintela imililo, ukulawula ukusasazeka kwabo, kunye negalelo elikhulu kukhuseleko lwemveliso kunye nobomi bemihla ngemihla. Izinto eziphathwayo ngeeretardants zomlilo zinokuthintela ngokufanelekileyo, zicothe, okanye zinqande ukusasazeka kwamadangatye xa evezwe kwimithombo yomlilo yangaphandle, ngaloo ndlela kuzuzwa iziphumo zokunqanda amadangatye. Kukho iintlobo ezininzi ze-flame retardants, kwaye yonke into inamacala amabini-i-flame retardants nazo zineenzuzo kunye neengxaki zazo. Apha ngezantsi kukho uhlalutyo lweenzuzo kunye nokungalunganga kweentlobo ezahlukeneyo ze-inorganic flame retardants.

Izinto ezingeloncedo kwi-Inorganic Flame Retardants:
I-drawback ephambili ye-inorganic flame retardants yi-dosage ephezulu efunekayo (ubukhulu becala ngaphezulu kwe-50%) kwimathiriyeli yepolymer, enokuthi yonakalise ngokulula ukusebenza kokusetyenzwa kunye neempawu zomzimba. Izisombululo zibandakanya unyango oluphezulu kunye nee-agent zokudibanisa, ukulungiswa kwe-ultrafine particle, kunye ne-nanotechnology, emele isikhokelo esiphambili sophuhliso lwexesha elizayo.

Izinto eziluncedo kwi-Inorganic Flame Retardants:

1. I-Aluminiyamu Hydroxide (ATH): Idibanisa ukubuyiswa komlilo, ukunyanzeliswa komsi, kunye nokuzalisa imisebenzi ibe nye. Ayinatyhefu, ayinayo i-corrosion, izinzile kakhulu, ayivelisi iigesi ezinobuthi kumaqondo obushushu aphezulu, ingabizi kakhulu, kwaye ifumaneka ngokubanzi.
2. I-Magnesium Hydroxide (MTH): Ibolisa phakathi kwe-340-490 ° C, inika uzinzo olubalaseleyo lwe-thermal kunye ne-flame retadancy ebalaseleyo kunye neziphumo zokunciphisa umsi. Ilungele ngokukodwa ukusetyenzwa kweeplastiki ze-polyolefin kumaqondo obushushu aphezulu.
3. I-Phosphorus ebomvu: Ibonelela ngokuthomalalisa umsi, ubutyhefu obuphantsi, kunye nokunqanda amadangatye okusebenzayo. Nangona kunjalo, i-phosphorus ebomvu ithanda ukukhutshwa emoyeni, inokutshisa ngokuzenzekelayo, kwaye ngokuthe ngcembe ikhuphe igesi eyityhefu yephosphine ekugcinweni kwexesha elide. Ukuhambelana kwayo kunye nezixhobo zepolymer kubi, kunye ne-microencapsulation isisombululo sokuqala.
4. I-Ammonium Polyphosphate (APP): Kwakhona i-intumescent flame retardant, iqulethe amanqanaba aphezulu e-nitrogen kunye ne-phosphorus, ibonisa ukuzinza okulungileyo kwe-thermal, kwaye iphantse ingathathi hlangothi ekuhlanganiseni. Inokuxutywa nezinye iiretardants zomlilo, inika ukusasazeka okuhle, kwaye iphantsi kwityhefu, iqinisekisa ukusetyenziswa ngokukhuselekileyo. Nangona kunjalo, xa idigri yepolymerization ye-APP iyancipha, iba yinto enyibilikayo emanzini. Ukongeza, i-APP ine-asidi kancinane kwaye ithanda ukufunxa ukufuma kwiindawo ezifumileyo.
