I-Aluminiyam ebuyisela i-Aluminiyam i-Hypophosphite kunye ne-MCA ye-EVA yoBubushushu-Shrink Tubing
Xa usebenzisa i-aluminiyam hypophosphite, i-MCA (i-melamine cyanrate), kunye ne-magnesium hydroxide njengezithinteli zedangatye kwi-EVA yokucutha ubushushu ityhubhu, uluhlu lwedosi ecetyiswayo kunye nezalathiso zokuphucula zezi zilandelayo:
1. Idosi ecetyiswayo yeeFrime Retardants
I-Aluminiyam Hypophosphite
- Umthamo:5%–10%
- Umsebenzi:Isebenza kakhulu i-flame retardant, ikhuthaza ukubunjwa kwe-char, kwaye inciphisa izinga lokukhutshwa kobushushu.
- Phawula:Izixa ezigqithisileyo zinokuphazamisa ukuguquguquka kwezinto; ii-arhente ze-synergistic kufuneka zibandakanywe ukuze kuphuculwe.
I-MCA (iMelamine Cynurate)
- Umthamo:10%–15%
- Umsebenzi:Igas-phase flame retardant, ifunxa ubushushu kwaye ikhuphe iirhasi ezingasebenziyo (umz., NH₃), i-synergizing ne-aluminiyam hypophosphite ukunyusa ukulibaziseka komlilo.
- Phawula:Ukugcwala kakhulu kunokubangela ukufuduka; ukuhambelana ne-EVA kufuneka kuqinisekiswe.
IMagnesium Hydroxide (Mg(OH)₂)
- Umthamo:20%–30%
- Umsebenzi:Ukubola kwe-endothermic kukhupha umphunga wamanzi, ukunyibilikisa iigesi ezinokutsha kunye nokucinezela umsi.
- Phawula:Ukulayisha okuphezulu kunokunciphisa iimpawu zoomatshini; ukuguqulwa komphezulu kuyacetyiswa ukuphucula ukusasazwa.
2. Iingcebiso zokuPhuculwa koKuqulunqwa
- ISixokelelwano esiBuyiselwa ngamadangatya:Akufunekanga idlule kwi-50% ukulinganisa ukubuyiswa komlilo kunye nokuqhubekeka (umzekelo, ukuguquguquka, izinga lokucutheka).
- Iziphumo zeSynergistic:
- I-aluminium hypophosphite kunye ne-MCA inokunciphisa imilinganiselo yomntu (umzekelo, i-8% ye-aluminium hypophosphite + 12% MCA).
- I-Magnesium hydroxide incedisa ukubuyiswa komlilo ngokusebenzisa iziphumo ze-endothermic ngelixa unciphisa umsi.
- Unyango loMphezulu:Iiarhente zokudityaniswa kweSilane zinokunyusa ukusasazwa kunye nokuhlangana kobuso be-magnesium hydroxide.
- Izongezo eziNcedisayo:
- Yongeza i-2% ukuya ku-5% yee-agent ezenza i-char-forming (umzekelo, i-pentaerythritol) ukuphucula uzinzo lwe-char layer.
- Dibanisa amanani amancinci eplastiki (umzekelo, i-oyile ye-soy epoxidized) ukubuyisela ilahleko yokuguquguquka.
3. Izalathiso zoQinisekiso lweNtsebenzo
- UVavanyo lweNkangala yedangatya:
- Uvavanyo lokutshisa oluthe nkqo UL94 (ithagethi: V-0).
- Ukunciphisa i-Oxygen Index (LOI> 28%).
- Iinkcazelo ngoomatshini:
- Vavanya amandla okuqina kunye nobude ngexesha lekhefu ukuqinisekisa ukuba uguquko luyahlangabezana neemfuno zesicelo.
- Ukuqhubekeka:
- Ukubeka iliso kwi-Melt Flow Index (MFI) ukuze ugweme ubunzima bokucubungula ngenxa yokugcwala okugqithisileyo.
4. Ukuqwalaselwa kweendleko kunye nokusiNgqongileyo
- Ixabiso eliseleyo:I-aluminiyam hypophosphite ixabisa kakhulu; umthamo wayo unokuncitshiswa (uncediswe nge-MCA) ukulawula iindleko.
- Ukuvumelana nokusiNgqongileyo:I-Magnesium hydroxide ayinayo ityhefu kwaye iyayicinezela umsi, iyenza ilungele ukusetyenziswa kwe-eco-friendly.
Ukuqulunqwa koMzekelo (kwireferensi kuphela):
- IAluminiyam Hypophosphite: 8%
- I-MCA: 12%
- I-Magnesium Hydoxide: 25%
- EVA Matrix: 50%
- Ezinye izongezo (ii-agent ezidibanisayo, iiplasitiki, njl. njl.): 5%
