Technical specification thiab engineering daim ntawv thov ntawm ntoo- cov khoom siv yas sib xyaw (Too-Plastic Composite, WPC)

Paub meej: Ntoo-cov khoom siv yas (WPCs) xa mus rau ib puag ncig cov ntaub ntawv sib xyaw ua ke ua los ntawm kev sib xyaw cov thermoplastic resins (xws li polyethylene, polypropylene, thiab polyvinyl chloride) nrog cov nroj tsuag fibers (xws li ntoo hmoov, nplej husks, thiab straw) los ntawm kev ua haujlwm siab -} kub 2.2. Daim ntawv no qhia txog qhov muaj pes tsawg leeg, qauv, cov yam ntxwv ntawm kev ua haujlwm, thiab kev siv ntawm cov ntaub ntawv no.

1. Cov khoom muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov txheej txheem

1.1 Cov txheej txheem thiab txheej txheem kev npaj

Cov nroj tsuag fiber ntau cov ntsiab lus hauv WPC cov ntaub ntawv sib xyaw yog li ntawm 35% mus rau 70% (los ntawm huab hwm coj), thiab tau ua tiav rau hauv cov qauv txheej txheem los ntawm extrusion, kub nias, lossis txhaj tshuaj molding nrog cov yas matrix. Cov txheej txheem txheej txheem muaj xws li: 0.5-1.2mm hnav- txheej tiv thaiv (alumina-inforced), 0.8-1.5mm hniav txheej (ntoo grain impregnated ntawv), thiab 3-25mm substrate txheej (fiber-yas composite core).

1.2 Cov kev ua haujlwm tseem ceeb

1.2.1 Lub cev thiab txhua yam khoom

Lub coefficient ntawm thermal expansion yog tsawg dua 4.5 × 10^-5 /℃(ntev), lub elastic modulus yog ntau tshaj 3.5GPa, thiab 24h dej nqus tus nqi yog tsawg dua 0.5%, uas ua tau raws li qhov yuav tsum tau ntawm ASTM D7031 tus qauv. Nws muaj qhov cuam tshuam loj heev (deformation<1.2% in 1000h) and anti-biodegradation performance (termite infestation grade 0).

1.2.2, kev siv tau

CNC precision machining tuaj yeem siv tau (txiav ceev 120-250m / min), tus ntsia thawv tuav quab yuam yog ntau dua 800N (ASTM D1761), thiab tus nqi tsim nyog ntawm kev ua haujlwm thib ob yog ntau dua 98%. Qhov saum npoo tuaj yeem ua tiav los ntawm UV txheej, hloov hluav taws xob thiab lwm yam txheej txheem.

1.2.3, kev sib koom ua ke ib puag ncig

Kev siv tus nqi ntawm cov khoom siv raw yog 92% (qhov feem ntawm cov khoom siv rov ua dua tshiab yog ntau dua 60%), VOC tso tawm yog<50μg/m³ (GB/T 29899-2013), and the recycling rate of materials is 100% (ISO 14021).

2. Engineering daim ntawv thov system

2.1 Tsev kho kom zoo nkauj engineering

- Cov txheej txheem sab nraum zoov: 8-25mm ntev profiles yog siv rau kev txhim kho pob tw (kev sib koom ua ke yog tsawg dua 0.3mm), uas yog tsim rau kev lag luam daim ntawv sau npe hauv ASTM F2942 tus qauv.

-Curtain wall system: B1 fire performance (GB 8624-2012), weather resistance test (3000h QUV) ΔE<2.5.

2.2 Kev lag luam khoom siv teb

-Logistics tsheb: pallet dynamic load yog ntau tshaj 1500kg (ISO 8611), tshuaj corrosion kuj qib IP6X.

-Qhov chaw hauv tsheb: ceev 1.1-1.3g/cm³, 15%-20% hnyav dua li cov khoom siv.

3. Kev sib piv thiab kev soj ntsuam ntawm cov khoom siv
