Thaum muab cov ntaub ntawv pov thawj hauv tsev rau kev lag luam, kev lag luam, lossis kev cia txias, kev kwv yees raug nqi yog qhov tseem ceeb. Xyoo 2026, cov nqi vaj huam sib luag yog tsav los ntawm cov khoom siv tseem ceeb, tuab, ntsuas steel, hom txheej, thiab cov khoom siv hauv cheeb tsam- cov khoom sib txawv uas cuam tshuam ncaj qha rau cov peev nyiaj thiab cov khoom sib piv.
Phau ntawv qhia no tawg2026 tus nqi thoob ntiaj tebrau PU, PIR, EPS, thiab pob zeb wool sandwich panels, nrog rau cov kev lag luam kev lag luam, daim ntawv thov -cov ntsiab lus xaiv tshwj xeeb, thiab cov nqi zais cia los pab cov neeg yuav khoom, engineers, thiab cov tswv lag luam ua cov ntaub ntawv - tsav kev txiav txim siab.
2026 Ntiaj teb Sandwich Vaj Huam Sib Luag Nqe (Los ntawm Cov Khoom Siv Core)
| Cov khoom siv tseem ceeb | Tus nqi ntau (FOB, $ / m²) | Tus nqi tseem ceeb tsav tsheb |
|---|---|---|
| EPS | $8 – $15/m² | Nyias steel (0.3-0.4mm), yooj yim PE txheej; tus nqi qis tshaj ua ntej |
| PU | $12 – $25/m² | Ntsuas rwb thaiv tsev / nqi; 0.4-0.5mm steel, txheej txheem txheej |
| PIR | $15 – $30/m² | Txhim khu kev tiv thaiv hluav taws; 0.45-0.6mm steel, PVDF txheej xaiv |
| Pob zeb Wool | $18 – $35/m² | Tsis yog -combustible core; hnyav- lub luag haujlwm framing, hluav taws- ntsuas khoom siv |
Nco tseg: Nqe qhia txog 50-100mm txheem thickness; 100–200mm panels ntxiv 20–40% rau cov nqi pib, thaum ntug hiav txwv / siab -UV cheeb tsam xav tau PVDF txheej (+10-15% hwm).
Core Material Performance & Cost Tradeoffs (Cov ntaub ntawv-Tom qab)
| Hom vaj huam sib luag | Rwb thaiv tsev Performance (R-value) | Hluav taws kub tsis kam | Hom Lifespan | Zoo tshaj rau |
|---|---|---|---|---|
| EPS | R-3 rau R-5 rau 50mm | Class E (limited hluav taws kub) | 15-20 xyoo | Cov nyiaj txiag warehouses, tsev qaib tsev |
| PU | R-5 rau R-7 rau 50mm | Chav Kawm B/C (tus kheej -kev tua) | 20-25 xyoo | General warehouses, chav txias |
| PIR | R-6 txog R-8 rau 50mm | Chav Kawm B (siab hluav taws kub) | 25-30 xyoo | Tswj kev lag luam, txias cia |
| Pob zeb Wool | R-3 rau R-4 rau 50mm | Class A (tsis yog-combustible) | 30+ xyoo | Hluav taws kub- cov tsev ntsuas, siab - thaj chaw nyab xeeb |
EPS: Tus nqi ntau tshaj - kev xaiv ua tau zoo, zoo tagnrho rau qis- cov phiaj xwm nyiaj txiag uas qhov hluav taws kub tsis muaj kev txhawj xeeb.
PU:Sib npaug thermal kev ua tau zoo thiab tus nqi, ua rau nws siv dav tshaj plaws rau kev lag luam thiab kev lag luam.
PIR: Muab cov rwb thaiv tsev zoo tshaj plaws thiab tiv thaiv hluav taws, ua pov thawj tus nqi rau cov haujlwm tswj hwm (xws li, khoom noj khoom haus txias cia, chaw tshuaj).
Pob zeb Wool:Cov tub ntxhais uas tsis yog-combustible cores raws li cov cai nruj, ua rau nws tseem ceeb rau siab - ib puag ncig kev nyab xeeb (xws li, cov ntaub ntawv chaw, refineries).
Thickness & Steel Specification Tus nqi cuam tshuam
1. Thickness Variation
Standard Warehouses: 50–100mm panels ($ 8– $25/m²) - sib npaug nqi thiab rwb thaiv tsev rau huab cua sov.
Txias Cia: 100–200mm panels (+20–40% premium) - tseem ceeb rau kev tswj hwm -20℃txog 4℃kub, txo cov nqi hluav taws xob mus sij hawm ntev los ntawm 30–50%.
Hluav taws kub-Rated Buildings: 80-150mm pob zeb wool panels - ua tau raws li cov qauv hluav taws xob tiv thaiv (1-2 teev hluav taws kub).
2. Hlau Gauge & Txheej
Hlau Thickness: 0.3mm (pob nyiaj) → 0.6mm (heavy-duty) ntxiv 10-25% rau vaj huam sib luag nqi; thicker steel txhim kho cua / daus load kuj.
Txheej hom:
PE txheej (tus qauv): $0–$2/m² premium – haum rau sab hauv, qis-UV cheeb tsam.
PVDF txheej (siab- durability): $2–$4/m² premium – yuav tsum tau rau ntug hiav txwv dej/siab-UV cheeb tsam (tiv thaiv corrosion rau 20+ xyoo).
Daim ntawv thov -Cov Lus Qhia Tshwj Xeeb Xaiv (2026)
| Daim ntawv thov | Pom zoo cov kev xaiv tseem ceeb | Xaiv Logic (Cov ntaub ntawv-Tom qab) |
|---|---|---|
| Lub tsev khaws khoom | PU / EPS / PIR | PU (60% kev sib koom ua lag luam) rau kev siv dav dav; PIR rau hluav taws- thaj chaw tswj hwm; EPS rau cov phiaj xwm nyiaj txiag. |
| Chav Txias | PU / PIR | Ob leeg muaj kev rwb thaiv tsev siab; PIR nyiam rau -20℃cia (zoo dua thermal stability). |
| Poultry House | EPS / PU tawv | EPS rau tus nqi- cov haujlwm tseem ceeb; PU rau huab cua txias (txo cov nqi cua sov los ntawm 25%). |
| Hluav taws kub-Rated Building | Pob zeb Wool / PIR | Pob zeb Wool (Class A) rau 2+ teev hluav taws kub; PIR (Class B) rau 1-teev hluav taws kub. |
| Ntug hiav txwv / siab -UV | Txhua Cores (PVDF Coated) | PVDF txheej yuav tsum tau tiv thaiv ntsev tsuag / UV degradation; ntxiv 10-15% rau tus nqi pib. |
Cov nqi zais rau xav txog (Tag nrho tus nqi ntawm cov tswv cuab)
Tshaj li tus nqi ntawm cov khoom siv, cov khoom no cuam tshuam tag nrho cov nqi ntawm qhov project:
Kev thauj mus los: $ 1– $ 5 / m² (nws txawv ntawm qhov deb; cov thawv ntim khoom txo nqi rau kev txiav txim ntau).
Kev teeb tsaNqe: $3–$8/m² (xovxwm + khoom siv: sealants, fasteners, trim pieces).
Kev tu: $0.5–$2/m²/xyoo (PVDF txheej txo nqi txij nkawm los ntawm 50% vs. PE txheej).
Kev txuag hluav taws xob: Thicker insulated panels txo cov nqi HVAC los ntawm 20-50% tshaj 20 xyoo, offsetting upfront premiums.
FAQ Module
Q: Dab tsi yog qhov pheej yig tshaj sandwich vaj huam sib luag hauv xyoo 2026?
A: EPS yog tus nqi tshaj plaws - kev xaiv zoo, Peb tuaj yeem muab tus nqi EXW tsawg li $6, zoo tagnrho rau cov phiaj xwm nyiaj txiag uas qhov hluav taws kub tsis yog qhov tseem ceeb.
Q: Puas yog PIR panels tsim nyog tus nqi siab dua piv rau PU?
A: Yog lawm rau cov haujlwm tswj hwm-PIR muaj 20% kev rwb thaiv tsev zoo dua thiab tiv thaiv hluav taws ntau dua, ua pov thawj rau 20-30% tus nqi rau cov khoom txias lossis cov tsev lag luam.
Q: Ntau npaum li cas thickness cuam tshuam rau sandwich vaj huam sib luag nqi?
A: Txhua qhov ntxiv 50 hli thickness ntxiv ~ 20% rau tus nqi pib.
Q: Cov txheej txheem twg yog qhov zoo tshaj plaws rau thaj tsam ntug hiav txwv?
A: PVDF txheej yog qhov yuav tsum tau ua - nws tiv taus cov tshuaj tsuag ntsev thiab UV hluav taws xob, txuas lub vaj huam sib luag lifespan los ntawm 10+ xyoo vs. PE txheej.
