Principle
Mumakore achangopfuura, kwave nekunetseka kuri kuwedzera nezve njodzi yezvakatipoteredza uye hutano hunokonzerwa nehalogen-based flame retardants inoshandiswa mumapurasitiki.Nekuda kweizvozvo, kwete-halogen murazvo retardants vakawana mukurumbira nekuda kweakachengeteka uye akasimba maitiro.
Halogen-isina flame retardants inoshanda nekuvhiringidza maitiro ekupisa anoitika kana mapurasitiki aiswa pamoto.
1.Vanoita izvi kuburikidza nekupindira kwepanyama uye kwemakemikari nemagasi anopisa anobudiswa panguva yekupisa.Imwe yemaitiro akajairika ndeyekuumbwa kwekabhoni inodzivirira pamusoro pepurasitiki.
2. Kana yaiswa mukupisa, halogen-isina flame retardants inopinda kemikari inogadzirisa, iyo inobudisa mvura kana mamwe magasi asingabatiki.Magasi aya anoita chipingamupinyi pakati pepurasitiki nemurazvo, nokudaro zvichideredza kupararira kwemoto.
3. Iyo halogen-isina moto retardants inoora uye inoumba yakagadzikana carbonized layer, inozivikanwa sechar, iyo inoshanda sechipingamupinyi chemuviri, kudzivirira kuwedzera kusunungurwa kwemagasi anopisa.
4. Uyezve, halogen-isina moto retardants inogona kuderedza magasi anopisa neionizing uye kutora mahara radicals uye zvinhu zvinopisa zvinopisa.Kuita uku kunonyatso kutyora kuita kweketani yekupisa, zvichiwedzera kuderedza kusimba kwemoto.
Ammonium polyphosphate ndeye phosphorus-nitrogen halogen-isina murazvo unodzoreredza.Iyo ine yakakwira moto inodzoreredza kuita mumapurasitiki asina-chepfu uye yezvakatipoteredza chimiro.
Plastics Application
Flame retardant mapurasitiki akaita seFR PP, FR PE, FR PA, FR PET, FR PBT uye zvichingodaro anowanzo shandiswa muindasitiri yemotokari yemukati memotokari, senge dashboard, mapaneru emasuo, zvikamu zvechigaro, magetsi evhavha, tambo dzetambo, moto kuramba. magetsi mapaneru, switchgears, magetsi akavharirwa, uye kutakura mvura, gasi pombi
Flame retardant standard (UL94)
UL 94 ipurasitiki yekupisa mwero yakaburitswa ne Underwriters Laboratories (USA).Muyero unoisa mapurasitiki maererano nemabatirwo aanoita munzvimbo dzakasiyana-siyana uye chikamu chakakora kubva kune yakaderera-inodzoreredza murazvo kusvika kune yakawanda-inodzoreredza murazvo muzvikamu zvitanhatu zvakasiyana.
| UL 94 Rating | Tsanangudzo Yekuyera |
| V-2 | Kupisa kunomira mukati memasekonzi makumi matatu pane chimwe chikamu chinobvumira madonhwe epurasitiki inobvira moto. |
| V-1 | Kupisa kunomira mukati memasekonzi makumi matatu pachikamu chakatwasuka chinobvumira madonhwe epurasitiki asiri kupisa. |
| V-0 | Kupisa kunomira mukati memasekonzi gumi pachikamu chakatwasuka chinobvumira madonhwe epurasitiki asiri kupisa. |
