I-ammonium polyphosphate enyibilikayo emanzini yi-flame retardant enobuhlobo nokusingqongileyo, iimveliso zayo zokubola aziyi kuvelisa izinto ezinobuthi, kwaye zinceda ekuthinteleni ukuveliswa komsi kwaye zinciphise ubungozi bomlilo kwimpilo yabantu nakwindalo esingqongileyo.
Kufuneka kuqatshelwe ukuba ukusetyenziswa kunye nomlinganiselo we-ammonium polyphosphate enyibilikayo emanzini kunokwahluka phantsi kwezixhobo ezahlukeneyo kunye neemeko zokusetyenziswa. Ngexesha lokusetyenziswa, uhlobo olungcono lokuthintela ilangatye kunye nendlela yokusebenzisa kufuneka kukhethwe ngokwemeko ethile, kwaye kufuneka kulandelwe iinkqubo zokusebenza ezifanelekileyo zokhuseleko ukuqinisekisa isiphumo sokuthintela ilangatye kunye nokhuseleko lokusetyenziswa.
Isicelo
1. Isisombululo samanzi sisetyenziselwa unyango oluthintela umlilo. Ukulungiselela i-20-25% PN flame retardant, esetyenziswa yodwa okanye kunye nezinye izinto kunyango oluthintela umlilo kwimpahla, amaphepha, imicu kunye neenkuni, njl.njl. Ukufaka nge-autoclave, ukuntywiliselwa okanye ngokutshiza zombini zilungile. Ukuba unyango olukhethekileyo, lungasetyenziselwa ukulungiselela ulwelo oluthintela umlilo olunoxinzelelo oluphezulu ukuya kwi-50% ukuhlangabezana neemfuno zokuvelisa okukhethekileyo.
2. Ingasetyenziswa njengesixhobo sokurhoxisa ilangabi kwisicima-mlilo esisekelwe emanzini kunye nevanishi yomthi,
3. Ikwasetyenziswa njengoxinzelelo olukhulu lwesichumiso esidityanisiweyo se-binary, isichumiso esikhutshwa kancinci.
