Cov Kev Dais Teeb Meem Rau Cov Yeeb Yaj Kiab PET Sheet
Tus neeg siv khoom tsim cov yeeb yaj kiab PET pob tshab uas tsis ua rau kub hnyiab nrog cov tuab ntawm 0.3 txog 1.6 hli, siv hexaphenoxycyclotriphosphazene (HPCTP) thiab nrhiav kev txo nqi. Hauv qab no yog cov qauv pom zoo thiab kev tshuaj xyuas ntxaws ntxaws rau cov yeeb yaj kiab PET pob tshab uas tsis ua rau kub hnyiab:
1. Kev Tshawb Fawb Txog Kev Xaiv Cov Khoom Uas Tiv Thaiv Tau Hluav Taws
Hexaphenoxycyclotriphosphazene (HPCTP)
- Cov Zoo: Cov tshuaj tua hluav taws uas muaj Phosphazene tawg tau zoo hauv PET, ua rau nws pom tseeb heev. Lub tshuab tua hluav taws no muaj kev sib xyaw ua ke ntawm cov pa roj thiab cov pa roj, ua rau nws tsim nyog rau cov yeeb yaj kiab pob tshab.
- Kev Siv Tshuaj: Pom zoo kom siv li ntawm 5% -10%. Kev siv ntau dhau yuav cuam tshuam rau cov khoom siv kho tshuab.
- Tus nqi: Siab dua, tab sis tag nrho cov nqi tseem tswj tau ntawm cov khoom thauj qis dua.
Aluminium Hypophosphite
- Qhov Tsis Zoo: Cov hmoov tsis muaj organic yuav ua rau muaj huab cua tsaus ntuj, cuam tshuam rau qhov pom tseeb. Tej zaum yuav xav tau qhov loj me ntawm cov khoom me me lossis kev hloov kho qhov chaw rau kev siv.
- Kev Siv Tau: Tsis pom zoo kom siv ib leeg xwb; tuaj yeem sib xyaw nrog HPCTP kom txo tau tag nrho cov nqi (yuav tsum tau kuaj pob tshab).
2. Cov Kev Xaiv Tsim Tshuaj Pom Zoo
Kev Xaiv 1: Ib Lub Tshuab HPCTP
- Cov qauv: 8% -12% HPCTP + PET cov ntaub ntawv puag.
- Cov Zoo: Kev pom tseeb zoo tshaj plaws thiab kev ua haujlwm siab tiv taus hluav taws (tuaj yeem ua tiav UL94 VTM-2 lossis VTM-0).
- Kwv yees tus nqi: Thaum thauj khoom 10%, tus nqi nce ib kg ntawm PET yog kwv yees li ¥10 (¥100/kg × 10%).
Xaiv 2: HPCTP + Aluminium Hypophosphite Blend
- Cov qauv: 5% HPCTP + 5% -8% txhuas hypophosphite + PET puag khoom.
- Cov Zoo: Txo tus nqi, nrog rau txhuas hypophosphite pab txhawb kev tiv thaiv hluav taws kub theem roj, tej zaum yuav txo tau kev siv HPCTP.
- Lus Cim: Yuav tsum tau kuaj xyuas seb puas muaj pob tshab (aluminium hypophosphite yuav ua rau muaj teeb meem me ntsis).
3. Cov Lus Qhia Txog Kev Ua thiab Kev Ntsuas
- Cov Txheej Txheem Dispersion: Siv lub tshuab extruder twin-screw kom ntseeg tau tias cov tshuaj tua hluav taws sib xyaw ua ke thiab zam kev sib sau ua ke uas cuam tshuam rau kev pom tseeb.
- Kev Ntsuas Hluav Taws Kub: Soj ntsuam raws li UL94 VTM lossis Oxygen Index (OI) cov qauv, tsom mus rau OI > 28%.
- Kev Ntsuas Pob Kaj: Ntsuas qhov tsaus ntuj siv lub ntsuas tsaus ntuj, xyuas kom meej tias tsaus ntuj < 5% (zaj duab xis tuab: 0.3-1.6 hli).
4. Kev Sib Piv Tus Nqi
Cov Khoom Siv Tiv Thaiv Hluav Taws Kub thiab Cov Nqi Ntxiv
| Hluav Taws Kub Tiv Thaiv | Thauj khoom | Tus nqi nce ntxiv rau ib kg PET |
|---|---|---|
| HPCTP (ib leeg) | 10% | ¥10 |
| HPCTP + Aluminium Hypophosphite | 5% + 5% | ¥6.8 [(5 × 100 + 5 × 37) / 100] |
| Aluminium Hypophosphite (ib qho) | 20% | ¥7.4 (tsis pom zoo) |
5. Xaus Lus
- Kev Xaiv Zoo Tshaj: HPCTP ib leeg ntawm 8% -10%, sib npaug pob tshab thiab hluav taws kub.
- Lwm Txoj Kev Xaiv: Sib xyaw ntawm HPCTP thiab txhuas hypophosphite, xav tau kev txheeb xyuas qhov pom tseeb thiab cov teebmeem synergistic.
Cov Lus Qhia: Tus neeg siv khoom yuav tsum ua qhov kev sim me me ua ntej, tsom mus rau kev tiv thaiv hluav taws (UL94/OI) thiab kev sim pa taws, tom qab ntawd ua kom zoo dua cov qauv thiab cov txheej txheem. Yog tias xav tau kev txo nqi ntxiv, tshawb nrhiav cov txhuas hypophosphite hloov kho saum npoo lossis cov tshuaj tiv thaiv hluav taws tshiab uas ua los ntawm phosphorus.
