Cov ntaub ntawv tsom xam ntawm PP (polypropylene) cov khoom siv: los ntawm cov qauv molecular mus rau cov ntawv thov tshiab
Zhejiang Gint Nqus Plua Plav Rleask Technology Co., Ltd.
1. Kev nkag siab tseem ceeb
Pp (polypropylene)yog aSemi-Crystalline ThermoplasticPolymerized los ntawm Propylene Monomers Monomers, qeb duas ntawm kaum tsib lub hom phiaj-lub hom phiaj plastics. Kev npaj ntawmMethyl Side Pab PawgNtawm nws cov molecular saw txiav txim siab peb serochemical configurations:
Isotactic PP (IPP): Methyl pawg ntawm tib sab, siab crystallinity (60-70%), feem ntau cov siv dav dav siv
Syndotactic PP (SPP): Lwm cov methyl pawg, siab pob tshab / toughness
Atactic Pp (app): Cov methyl pawg, tsawg crystallinity, siv raws li cov nplaum
2. Cov kev ua tau tseem ceeb
| Ntiag tug | Cov nqi raug | Vs. Lwm Cov Ntawv Uas |
|---|---|---|
| Ceev | 0.89-0.91 g / cm³ | Nyom general yas |
| Melting point | 160-170℃(IPP) | Siab dua pe (120 degree) |
| Lub zog tensile | 25-40 MPA | Zoo dua HDPE, qis dua Pa6 |
| FLEXURAL Modulus | 1.1-1.6 GPA | Stiffer tshaj HDPE |
| HDT (0.45mpa) | 100-120 Qib | Microwave-nyab xeeb |
| Dielectric lub zog | 20-28 KV / hli | Cov rwb thaiv tsev zoo heev |
3. Tsib tus ntsiab lus zoo
Lub teeb yuag
30% sib dua dua li tsiaj, 80% sib dua dua iav; txo cov tsheb pob tw 'qhov hnyav los ntawm 40%
Kev Siv Tshuaj Kho Mob
Tsis kam p1-14 acids / alkalis (tsuas yog oxidizers muaj zog); nyiam rau cov cuab yeej siv dag zog kho mob
Cov Khoom Noj-Qib Nyab Xeeb
FDA 21 CFR 177.1520 Raws; Haum rau tus me nyuam fwj
Cov Thawj Tswj Xyuas Cov Neeg Ceev Xwm
Recycling code "5"; Borealis tsim 100% rov ua dua PP (BORKNACT ™ CHAV)
Versatility
Haum rau kev txhaj tshuaj / Extrusion / Thermoforming; MFr ntau: 0.5-100g / 10min
4. Daim ntawv thov evolution
1st gen (1960): Ntim cov yeeb yaj kiab, cov fibers
Thib 2 (1980s): Lub tsev dashboard, siv lub tsev
3RD GEN (2000s):
Kev Kho Mob: Biodegradable sutures (PP + PLA sib xyaw)
Zog: Li-Ion Roj Teeb Separator (Biaxous-Oriented Pp)
Additive MFG .: PP Hmoov Rau SLS 3D Printing
5. Ib puag ncig cov nyom
Uv Kev Ruaj Ntseg: Chanppression; Hals ntxiv ntxiv txuas sab nraum zoov lub neej rau 5+ xyoo
Tsawg-kub brittleness: Cuam tshuam lub zog plummets hauv qab -20 degree; txhim kho nrog Epr Blending
Nkag: Nruam thauj khoom tsis tu ncua; 50% txo nrog iav fiber ntau txhawb
6. ICCOLITATIONS Frontiers
Siab heev melt lub zog PP (HMYPP)
Ntev-saw branching rau Ntim Npuas (Hloov Ps)
Antimicrobial pp
Silver ions / QueMonium Salts Txo cov kab mob saum tsev kho mob thaum 99%
Tus Tsim Kho PP
Thermochromic PP: Hloov pauv xim ntawm 65 Degree + (Cov Khoom Noj Menyuam)
7. Cov Khoom Siv Hluav Taws Xob
Cov neeg muag khoom sab saum toj:
Borealis (Blouge)
Lyondellbasell (Hostalen)
Mitsui Tshuaj (Prime PolyPro)
Tus Tsheb Tsav:
Propylene Monomer (txuas rau cov roj nyoos)
Automotive Thov Mus Ncig
8. Tom ntej-xyoo caum kwv yees
Bio raws PP: Braskem cov suab thaj tsam ethanol-rau-PP lag luam
Supercritical foo yog pp: Mercedes rooj tog: 30% kev txo phaus
Kho tus kheej pp: Microencapsulated dcpd monomers rau kos kho
