Iingenelo kunye nokungalungi kwezinto ezithintela ilangatye ezingaphiliyo

Ukusetyenziswa ngokubanzi kwezinto zepolymer kuye kwakhawulezisa ukukhula kweshishini lezinto ezithintela umlilo. Izinto ezithintela umlilo ziyinxalenye ebalulekileyo yezinto ezongeziweyo kuluntu lwanamhlanje, zithintela umlilo ngempumelelo, zilawula ukusasazeka kwawo, kwaye zinegalelo elikhulu kukhuseleko lwemveliso kunye nobomi bemihla ngemihla. Izinto eziphathwe ngezinto ezithintela umlilo zinokuthintela ngempumelelo, zicothise, okanye ziyeke ukusasazeka komlilo xa zichatshazelwa yimithombo yomlilo yangaphandle, ngaloo ndlela zifezekisa iziphumo ezithintela umlilo. Kukho iintlobo ezininzi zezinto ezithintela umlilo, kwaye yonke into inamacala amabini—izinto ezithintela umlilo nazo zinezibonelelo kunye neengxaki zazo. Apha ngezantsi kukho uhlalutyo lweengenelo kunye neengxaki zezinto ezahlukeneyo ezithintela umlilo ezingaphiliyo.

Izinto ezingalunganga ezithintela ilangatye kwi-Inorganic:
Eyona ngxaki iphambili ye-inorganic flame retardants yi-dosage yazo ephezulu efunekayo (ubukhulu becala ngaphezulu kwama-50%) kwizixhobo ze-polymer, ezinokuthi zonakalise ukusebenza kakuhle kokucubungula kunye neempawu zomzimba. Izisombululo ziquka unyango lomphezulu ngee-coupling agents, i-ultrafine particle refine, kunye ne-nanotechnology, ezimele ulwalathiso oluphambili lophuhliso lwexesha elizayo.

Iingenelo zezinto ezithintela ilangatye ezingaphiliyo:

1. I-Aluminium Hydroxide (ATH): Idibanisa imisebenzi yokulibaziseka komlilo, ukucima umsi, kunye nokuzalisa ibe yinto enye. Ayinatyhefu, ayibolisi, izinzile kakhulu, ayivelisi iigesi ezinobuthi kumaqondo obushushu aphezulu, ixabisa kancinci, kwaye ifumaneka ngokubanzi.
2. I-Magnesium Hydroxide (MTH): Iyabola phakathi kwama-340–490°C, inika uzinzo oluhle kakhulu kubushushu kunye nokungacimi komlilo okubalaseleyo kunye nemiphumo yokucinywa komsi. Ifanelekile ngokukodwa ekucutshungulweni kweeplastiki ze-polyolefin kumaqondo obushushu aphezulu.
3. I-Phosphorus ebomvu: Inika ukuthintela umsi, ityhefu ephantsi, kwaye iyasebenza kakhulu ekunqandeni amalangatye. Nangona kunjalo, i-phosphorus ebomvu ithambekele ekutshisweni yi-oxidation emoyeni, inokutsha ngokuzenzekelayo, kwaye ikhuphe kancinci igesi ye-phosphine enobuthi ngexesha lokugcina ixesha elide. Ukuhambelana kwayo nezinto ze-polymer akulunganga, kwaye isisombululo esiphambili yi-microencapsulation.
4. I-Ammonium Polyphosphate (APP): Ikwayi-intumescent flame retardant, inezinga eliphezulu le-nitrogen kunye ne-phosphorus, ibonakalisa uzinzo oluhle lobushushu, kwaye ayithathi cala ekubunjweni kwayo. Ingaxutywa nezinye izinto ezithintela umlilo, inika ukusasazeka okuhle, kwaye ayinatyhefu ingako, nto leyo eqinisekisa ukusetyenziswa ngokukhuselekileyo. Nangona kunjalo, xa i-APP inciphisa i-polymerization degree, iba yinto enyibilikayo emanzini. Ukongeza, i-APP ine-asidi encinci kwaye ithambekele ekufunxeni umswakama kwiindawo ezifumileyo.
