Nplaim Retardant Solutions rau PET Sheet Films
Cov neeg siv khoom tsim pob tshab nplaim nplaim-retardant PET daim ntawv zaj duab xis nrog tuab ntawm 0.3 txog 1.6 hli, siv hexaphenoxycyclotriphosphazene (HPCTP) thiab nrhiav kev txo nqi. Hauv qab no yog cov qauv kev pom zoo thiab cov ncauj lus kom ntxaws tsom xam rau pob tshab nplaim-retardant PET zaj duab xis:
1. Kev soj ntsuam ntawm kev xaiv nplaim hluav taws
Hexaphenoxycyclotriphosphazene (HPCTP)
- Qhov zoo: Phosphazene-raws li nplaim retardants disperse zoo nyob rau hauv PET, tswj siab transparency. Cov nplaim-retardant mechanism suav nrog condensed-theem charring thiab roj-theem radical trapping, ua rau nws haum rau cov yeeb yaj kiab pob tshab.
- Kev Siv Tshuaj: Pom zoo ntawm 5% -10%. Cov nyiaj ntau dhau tuaj yeem cuam tshuam rau cov khoom siv kho tshuab.
- Tus nqi: Zoo sib xws, tab sis tag nrho cov nqi tseem tswj tau ntawm cov khoom qis dua.
Aluminium Hypophosphite
- Qhov tsis zoo: Cov hmoov tsis zoo yuav ua rau haze, cuam tshuam rau pob tshab. Ultra-fine particle loj lossis kev hloov kho saum npoo yuav xav tau rau kev siv.
- Kev siv tau: Tsis pom zoo ib leeg; tuaj yeem sib xyaw nrog HPCTP kom txo tau tus nqi tag nrho (kev kuaj pom pom tseeb).
2. Pom zoo xaiv Formulation
Kev xaiv 1: Tib HPCTP System
- Formulation: 8% -12% HPCTP + PET cov khoom siv.
- Qhov zoo: Qhov zoo tshaj plaws pob tshab thiab cov nplaim hluav taws kub-retardant efficiency (tuaj yeem ua tiav UL94 VTM-2 lossis VTM-0).
- Tus nqi kwv yees: Ntawm 10% kev thauj khoom, tus nqi nce ib kg ntawm PET yog kwv yees li ¥ 10 (¥ 100 / kg × 10%).
Kev xaiv 2: HPCTP + Aluminium Hypophosphite Blend
- Formulation: 5% HPCTP + 5% -8% aluminium hypophosphite + PET puag khoom.
- Qhov zoo: txo nqi, nrog txhuas hypophosphite pab hauv roj-theem nplaim hluav taws xob, muaj peev xwm txo tau kev siv HPCTP.
- Nco tseg: Transparency yuav tsum tau kuaj (txhuas hypophosphite tej zaum yuav ua rau haze me ntsis).
3. Cov lus pom zoo ua haujlwm thiab kuaj
- Cov txheej txheem Dispersion: Siv ib tug ntxaib-ntsia hlau extruder los xyuas kom meej cov dispersion ntawm nplaim retardants thiab tsis txhob agglomeration cuam tshuam rau pob tshab.
- Nplaim Retardancy Testing: Ntsuas raws li UL94 VTM lossis Oxygen Index (OI) cov qauv, tsom OI> 28%.
- Transparency Testing: Ntsuas qhov kub hnyiab uas siv lub ntsuas cua daj cua dub, kom ntseeg tau tias haze <5% (film thickness: 0.3-1.6 mm).
4. Tus nqi sib piv
Nplaim Retardant loading thiab nqi nce rooj
| Nplaim Retardant | Chaw thau khoom | Tus nqi nce ib kg PET |
|---|---|---|
| HPCTP (ib leeg) | 10% | ¥10 |
| HPCTP + Aluminium Hypophosphite | 5% + 5% | ¥ 6.8 [(5 × 100 + 5 × 37) / 100] |
| Aluminium Hypophosphite (ib leeg) | 20% | ¥ 7.4 (tsis pom zoo) |
5. Cov lus xaus
- Kev xaiv zoo dua: HPCTP ib leeg ntawm 8% -10%, ntsuas qhov pom tseeb thiab nplaim hluav taws.
- Lwm txoj kev xaiv: Kev sib xyaw ntawm HPCTP thiab txhuas hypophosphite, xav tau kev txheeb xyuas qhov pom tseeb thiab muaj txiaj ntsig zoo.
Cov lus pom zoo: Cov neeg siv khoom yuav tsum ua qhov kev sim me me ua ntej, tsom mus rau cov nplaim hluav taws kub hnyiab (UL94 / OI) thiab kev ntsuas kub hnyiab, tom qab ntawd txhim kho cov qauv thiab txheej txheem. Yog xav tau kev txo nqi ntxiv, tshawb xyuas qhov chaw hloov kho aluminium hypophosphite los yog tshiab phosphorus-raws li nplaim hluav taws retardants.
