Mumakore achangopfuura, kwave nekunetseka kuri kuwedzera pamusoro penjodzi dzezvakatipoteredza uye hutano dzinokonzerwa nezvinodzivirira moto zve halogen zvinoshandiswa mumapurasitiki. Nekuda kweizvozvo, zvinodzivirira moto zvisiri halogen zvave kufarirwa nekuda kwehunhu hwazvo hwakachengeteka uye hunogara kwenguva refu.
Zvinhu zvinodzivisa moto zvisina halogen zvinoshanda nekuvhiringidza mashandiro ekutsva anoitika kana mapurasitiki apiswa nemoto.
1. Vanoita izvi nekushandisa makemikari uye nemuviri kupindira mumagasi anobvira anoburitswa panguva yekutsva. Imwe yenzira dzakajairika ndeyekuumbwa kwechikamu chekabhoni chinodzivirira pamusoro pepurasitiki.
2. Kana zvaiswa pakupisa, zvinodzivisa moto zvisina halogen zvinosangana nemakemikari, izvo zvinoburitsa mvura kana mamwe magasi asingatsvi. Magasi aya anogadzira chipingamupinyi pakati pepurasitiki nemurazvo, nokudaro zvichideredza kupararira kwemoto.
3. Zvinodzora moto zvisina halogen zvinoora zvoita ganda rakagadzikana, rinozivikanwa sechar, iro rinoshanda sechidziviriro chemuviri, richidzivirira kuburitswa kwemagasi anobvira.
4. Uyezve, zvinodzora moto zvisina halogen zvinogona kuderedza magasi anobvira nekuita kuti mafree radicals nezvikamu zvinobvira zvinoputika. Izvi zvinokanganisa mashandiro emoto, zvichideredza simba remoto.
Ammonium polyphosphate inodzivirira moto isina phosphorus-nitrogen halogen. Inoshanda zvakanyanya mupurasitiki isina chepfu uye ine hunhu hwezvakatipoteredza.
Kushandiswa kwepurasitiki
Mapurasitiki anodzivirira moto akadai seFR PP, FR PE, FR PA, FR PET, FR PBT nezvimwewo anoshandiswa zvakanyanya muindasitiri yemotokari mukuisa mukati memota, senge madhibhodhi, mapaneru emusuwo, zvikamu zvezvigaro, nzvimbo dzemagetsi, matireyi etambo, mapaneru emagetsi anodzivirira moto, maswitchgears, nzvimbo dzemagetsi, uye kutakura mvura, mapaipi egasi.
Muyero unodzora moto (UL94)
UL 94 imhando yepurasitiki inogona kupisa yakaburitswa neUnderwriters Laboratories (USA). Iyi nzira inoisa mapurasitiki mumapoka zvichienderana nekuti anopisa sei muzvikamu zvakasiyana-siyana uye ukobvu hwezvikamu kubva pane yakaderera inodzivirira moto kusvika kune yakawanda inodzivirira moto muzvikamu zvitanhatu zvakasiyana.
| Chiyero cheUL 94 | Tsanangudzo yeKuyera |
| V-2 | Kupisa kunomira mukati memasekonzi makumi matatu pachikamu ichi zvichiita kuti madonhwe epurasitiki inobvira yakamira. |
| V-1 | Kupisa kunomira mukati memasekonzi makumi matatu panzvimbo yakamira zvichiita kuti madonhwe epurasitiki asingatsvi. |
| V-0 | Kupisa kunomira mukati memasekonzi gumi panzvimbo yakamira zvichiita kuti madonhwe epurasitiki asingatsvi. |
