Ntugharị nrụtụ aka nke PVC Flame Retardant Masterbatch
Nhazi na njikarịcha nke usoro ihe ọkụkụ na-ere ọkụ nke PVC, na-etinye ihe ndị na-ere ọkụ dị ugbu a na ihe ndị na-emekọ ihe ọnụ, na-ezubere ire ọkụ ọkụ UL94 V0 (gbanwee na V2 site na ibelata ego mgbakwunye).
I. Nkwanye usoro ntọala (PVC siri ike)
Nhazi nke ire ọkụ plastik:
| Akụkụ | Na-ebu (wt%) | Nkọwa ọrụ |
|---|---|---|
| PVC resin (ụdị SG-5) | 40-50% | Ihe Matrix, ọkachamma ọkwa nnabata mmanụ dị ala |
| Aluminom hypophosphite | 12-15% | Isi iyi acid maka nhazi cha cha, na-egbochi ọkụ mgbe ọkụ gasịrị |
| Zinc borate | 8-10% | Mbelata anwụrụ ọkụ synergistic, na-emeghachi omume na HCl site na ire ere PVC |
| Aluminom hydroxide gbanwechara elu | 10-12% | Endothermic jụrụ oyi, na-achọ mkpuchi maka njikọ njikọta nke silane (decomposition temp. dakọtara na nhazi PVC) |
| Antimony trioxide (Sb₂O₃) | 3-5% | Core synergist, na-akwalite nkwụghachi ọkụ site na mmekọrịta Cl-Sb |
| Zinc molybdate (ihe na-egbochi anwụrụ ọkụ) | 5-8% | Ihe mgbakwunye akwadoro, na-ebelata njupụta anwụrụ ọkụ (igodo maka nnabata DIN 4102) |
| Dipentaerythritol (DPE) | 2-3% | Enyemaka akpụ akpụ, na-emezi njikwa mgbaze-drip |
| Thermal stabilizer (Ca-Zn mejupụtara) | 3-4% | Ihe dị mkpa iji gbochie mmebi okpomọkụ n'oge nhazi |
| Plasticizer (DOP ma ọ bụ eco-alternative) | 0-8% | Gbanwee maka ike ike (nhọrọ maka PVC siri ike) |
| mmanu mmanu (calcium stearate) | 1-1.5% | Na-eme ka usoro nhazi dịkwuo mma, na-egbochi ịrapagidesi ike |
| Enyemaka nhazi (ACR) | 1-2% | Na-akwalite plasta na masterbatch mgbasa |
II. Ụkpụrụ njikarịcha igodo
- Sistemụ Mmekọrịta Ọkụ Retardant
- Mmekọrịta Cl-Sb: chlorine dị n'ime PVC (56%) jikọtara ya na 3-5% Sb₂O₃ na-eme ihe mgbochi SbCl₃, na-eme ka ọkụ-phase/condensed-phase dual-action retardanancy.
- Mgbochi anwụrụ ọkụ: Zinc molybdate + zinc borate na-ebelata njupụta anwụrụ ọkụ site na> 40% (ASTM E662).
- Nkwalite Char: Aluminom hypophosphite + DPE na-ebute phosphoric ester char jikọtara ya na 200–250C, na-akwụ ụgwọ maka ụkọ cha cha nke mbụ nke PVC.
- Nhazi nhazi
- Okpomọkụ ndakọrịta: Aluminom hypophosphite (decomposition ≥250 ° C) na elu-gbanwetụrụ Al (OH) ₃ (kwụsi ike> 200 ° C) dabara PVC nhazi (160-190 ° C).
- Nkwenye nkwụsi ike: Ca-Zn stabilizers na-egbochi mmebi resin site na ntọhapụ HCl; ACR na-enyere aka plasta n'ime sistemu dị elu.
- Ntụle arụmọrụ
- Mkpokọta ọkụ retardant loading: 35-45%, tensile ike njide ≥80% (ahụkarị ≥40 MPa maka isiike PVC).
- Maka mgbanwe (PVC na-agbanwe agbanwe), dochie DOP na mmanụ soybean 8% epoxidized (plastaizer abụọ / ire ọkụ).
III. Nnwale & Nnwale Metrics
Ọnwụ Ọkụ:
- UL94 V0 (ọkpụrụkpụ 1.6 mm)
- Oke Oxygen Index (LOI) ≥32%
Njikwa anwụrụ ọkụ:
- Nnwale ụlọ anwụrụ ọkụ NBS: njupụta ngwa anya kachaDs≤150 (ụdị ọkụ)
Ngwongwo igwe:
- Ike tensile ≥35 MPa (isi ike), elongation na ezumike ≥200% (mgbanwe)
Nkwụsi ike okpomọkụ:
- DMA na-akwado na ọ dịghị modul ọdịda na 180ºC.
IV. Ọnụ & Ndozi Eco-Enyi na Enyi
Nhọrọ dị ọnụ ala:
- Belata zinc molybdate ka ọ bụrụ 3%, jiri Mg(OH)₂ dochie Al(OH)₃ n'akụkụ ụfọdụ (abawanye ruo 15%).
Ngwọta na-enweghị Antimony:
- Wepu Sb₂O₃, jiri 2% aluminum diethylphosphinate + 5% nano-kaolin (obere arụmọrụ dị ntakịrị; chọrọ ọkpụrụkpụ 3 mm maka V0).
Ihe mbụ anwụrụ ọkụ:
- Tinye 1% carbon ojii nwere mkpuchi silicone iji belata njupụta anwụrụ ọkụ site na 15%.
V. Ntuziaka nhazi
- Usoro ngwakọta:
PVC resin → stabilizer + mmanu mmanu → ọkụ retardants (dị ala na elu njupụta) → plasticizer (gbara-gbakwụnye ikpeazụ). - Okpomọkụ Nhazi:
Mpaghara ejima-skru extruder: 160°C (nri) → 170°C (agbaze) → 180°C (ịgwakọta) → 175°C (isi anwụ anwụ). - Ntinye uche Masterbatch:
Kwado 50% ibu; dilu 1: 1 na PVC na-amaghị nwoke maka ịkpụzi injection.
Nhazi a na-edozi ogologo oge ọkụ dị elu, obere anwụrụ ọkụ, na nkwụsi ike nhazi. A na-adụ ọdụ ule ndị dị ntakịrị tupu ịchachaa, na mgbanwe ndị dabere na ụdị ngwaahịa (ibé akwụkwọ, eriri, wdg).
