Isimiso
Eminyakeni yamuva nje, kube nokukhathazeka okukhulayo mayelana nezingozi zemvelo nempilo ezidalwa yi-halogen-based flame retardants esetshenziswa kumapulasitiki.Ngenxa yalokho, ama-non-halogen flame retardants athole ukuthandwa ngenxa yezici zawo eziphephile nezizinzile.
Izinqamuleli zamalangabi ezingenalo i-halogen zisebenza ngokuphazamisa izinqubo zokuvutha ezenzeka lapho amapulasitiki echayeka emlilweni.
I-1.Bafinyelela lokhu ngokuphazamisa ngokomzimba namakhemikhali kumagesi avuthayo akhishwa ngesikhathi sokusha.Enye yezindlela ezivamile iwukwenza ungqimba lwekhabhoni oluvikelayo ebusweni bepulasitiki.
2. Lapho zichayeka ekushiseni, izinto ezibuyisela amalangabi ezingenalo i-halogen zithola ukusabela kwamakhemikhali, okukhulula amanzi noma amanye amagesi angashi.La magesi akha umgoqo phakathi kwepulasitiki nelangabi, ngaleyo ndlela abambezele ukubhebhetheka komlilo.
3. I-halogen-free flame retardants iyabola futhi yakhe ungqimba oluzinzile lwe-carbonized, olwaziwa ngokuthi i-char, olusebenza njengesithiyo esibonakalayo, esivimbela ukukhululwa okuqhubekayo kwamagesi avuthayo.
4. Ngaphezu kwalokho, i-halogen-free flame retardants inganciphisa amagesi avuthayo ngokufaka i-ionizing futhi ibambe ama-radicals mahhala kanye nezingxenye ezivuthayo ezivuthayo.Lokhu kusabela kwephula ngempumelelo ukusabela kweketango lokusha, kuqhubeke kunciphisa amandla omlilo.
I-Ammonium polyphosphate iyi-phosphorus-nitrogen ene-halogen-free retardant.Inokusebenza okuphezulu kwe-flame retardant kumapulasitiki anesici esingenabuthi nemvelo.
Plastiki Isicelo
Amapulasitiki abushelelezi amalangabi afana ne-FR PP, FR PE, FR PA, FR PET, FR PBT nokunye avame ukusetshenziswa embonini yezimoto endaweni yangaphakathi yemoto, njengamadeshibhodi, amapaneli eminyango, izingxenye zesihlalo, izivalo zikagesi, amathreyi ekhebula, ukumelana nomlilo. amaphaneli kagesi, ama-switchgears, izivalo zikagesi, namanzi athuthayo, amapayipi egesi
I-Flame retardant standard (UL94)
I-UL 94 iyindinganiso yokuvutha kwamapulasitiki ekhishwe yi-Underwriters Laboratories (USA).Izinga lihlukanisa amapulasitiki ngokuya ngokuthi asha kanjani emimoyeni ehlukahlukene kanye nengxenye yogqinsi ukusuka kwenganqamuki ilangabi eliphansi kakhulu kuye kwezinganqamuki ilangabi kakhulu ezigabeni eziyisithupha ezihlukene.
Isilinganiso se-UL94 | Incazelo Yesilinganiso |
V-2 | Ukushiswa kuyama phakathi nemizuzwana engu-30 engxenyeni evumela amathonsi epulasitiki evutha eqondile. |
V-1 | Ukushiswa kuyama phakathi nemizuzwana engu-30 engxenyeni eqondile okuvumela amathonsi epulasitiki angavuvukali. |
V-0 | Ukushiswa kuyama phakathi nemizuzwana eyi-10 engxenyeni eqondile okuvumela amathonsi epulasitiki angavuvukali. |
