| Olomi (calcium stearate) | 1-1.5% | Ṣe ilọsiwaju ilana ilana, ṣe idiwọ duro rola |
| Iranlowo ilana (ACR) | 1-2% | Ṣe ilọsiwaju pilasitiki ati pipinka masterbatch |
II. Awọn Ilana Imudara bọtini
- Ina Retardant Synergy System
- Amuṣiṣẹpọ Cl-Sb: chlorine inherent PVC (56%) ni idapo pẹlu 3-5% Sb₂O₃ ṣe idiwọ SbCl₃ kan, ti n mu agbara gaasi-fase/condensed-phase meji-igbese imuduro ina.
- Imukuro ẹfin: Zinc molybdate + borate zinc dinku iwuwo ẹfin nipasẹ> 40% (ASTM E662).
- Imudara Char: Aluminiomu hypophosphite + DPE n ṣe agbekọja phosphoric ester char ti o ni asopọ agbelebu ni 200–250°C, isanpada fun aipe-ipele chaja PVC.
- Iṣatunṣe Iṣeṣe
- Ibamu iwọn otutu: Aluminiomu hypophosphite (idibajẹ ≥250 ° C) ati dada-atunṣe Al (OH) ₃ (iduroṣinṣin si> 200 ° C) ti o baamu sisẹ PVC (160-190 ° C).
- Idaniloju Iduroṣinṣin: Awọn amuduro Ca-Zn ṣe idiwọ ibajẹ resini lati itusilẹ HCl; ACR ṣe iranlọwọ plastification ni awọn eto kikun-giga.
- Iwontunws.funfun Performance
- Lapapọ ikojọpọ ina retardant: 35-45%, idaduro agbara fifẹ ≥80% (aṣoju ≥40 MPa fun PVC kosemi).
- Fun irọrun (PVC to rọ), rọpo DOP pẹlu epo soybean 8% epoxidized (plastiizer meji / idaduro ina).
III. Idanwo & Awọn Metiriki Afọwọsi
Idaduro Iná:
- UL94 V0 ( sisanra 1.6 mm)
- Atọka Atẹgun Idiwọn (LOI) ≥32%
Iṣakoso ẹfin:
- Idanwo iyẹwu ẹfin NBS: iwuwo opitika kan pato ti o pọjuDs≤150 (ipo ina)
Awọn ohun-ini ẹrọ:
- Agbara fifẹ ≥35 MPa (kosemi), elongation ni Bireki ≥200% (rọ)
Iduroṣinṣin Ooru:
- DMA jẹrisi ko si modulus silẹ ni 180°C.
IV. Iye & Awọn atunṣe Ọrẹ-Eko
Idakeji Iye-kekere:
- Din zinc molybdate dinku si 3%, ni apakan kan rọpo Al(OH)₃ pẹlu Mg(OH)₂ (pọ si 15%).
Ojutu Ọfẹ Antimony:
- Yọ Sb₂O₃, lo 2% aluminiomu diethylphosphinate + 5% nano-kaolin (ṣiṣe kekere diẹ; nilo sisanra 3 mm fun V0).
Ẹfin pataki:
- Ṣafikun 1% dudu erogba resini silikoni lati dinku iwuwo ẹfin siwaju nipasẹ 15%.
V. Awọn ilana Ilana
- Ilana Idapọ:
PVC resini → amuduro + lubricant → ina retardants (kekere si giga iwuwo) → plasticizer (sokiri-fi kun kẹhin). - Awọn iwọn otutu ti nṣiṣẹ:
Twin-skru extruder agbegbe: 160 ° C (ono) → 170 ° C (yo) → 180 ° C (adapọ) → 175 ° C (ku ori). - Iṣọkan Masterbatch:
Ṣe iṣeduro 50% ikojọpọ; dilute 1: 1 pẹlu wundia PVC fun ipari-lilo abẹrẹ igbáti.
Ilana yii ṣe iwọntunwọnsi idaduro ina giga, ẹfin kekere, ati iduroṣinṣin sisẹ. Awọn idanwo iwọn-kekere ni imọran ṣaaju ki o to iwọn, pẹlu awọn atunṣe ti o da lori fọọmu ọja (awọn iwe, awọn kebulu, bbl).
