Polypropylene Honeycomb Core Khoom siv

A: PP (polypropylene) honeycomb core yog lub teeb yuag, thermoplastic honeycomb qauv tsim los ntawm extruded polypropylene hlab uas yog thermally bonded ua ke los tsim ib tug nruam hexagonal los yog voj cell matrix. PP honeycomb cores muaj kev cuam tshuam zoo heev, tiv thaiv dej noo, tshuaj lom neeg tsis muaj zog, thiab rov ua dua tshiab ntawm tus nqi qis dua aluminium lossis aramid (Nomex) honeycombs. Lawv tau dav siv los ua cov khoom siv tseem ceeb hauv cov khoom sib xyaw ua ke sib xyaw ua ke rau cov tsheb sab hauv, kev thauj mus los, kev tsim kho, rooj tog zaum, ntim khoom, thiab kev siv hluav taws xob tauj dua tshiab. PP honeycomb cores feem ntau yog muab rau hauv cov ntawv tiaj tus lossis cov yob txuas ntxiv thiab sib xws nrog ntau yam ntawm cov ntaub ntawv suav nrog txhuas, FRP (fiberglass), plywood, thiab cov ntawv thermoplastic bonded nrog polyurethane, epoxy, los yog kub- cov nplaum nplaum.

A: ① Tus nqi- zoo: PP honeycomb yog 40-60% qis dua aluminium honeycomb thiab 70-80% tsawg dua aramid (Nomex) honeycomb ib square meter ntawm qhov sib npaug thickness.
② 100% waterproof thiab ya raws- pov thawj: polypropylene absorbs zero dej (<0.01% after 24h immersion). Unlike paper honeycomb or wood-based cores, PP will never swell, rot, or support mold growth - ideal for marine, outdoor, and wet-area applications.
③ Kev cuam tshuam - tiv taus thiab tawv: PP yog cov khoom siv thermoplastic uas muaj kev cuam tshuam zoo rau lub zog nqus. Tsis zoo li brittle ua npuas ncauj cores (PVC, PET, SAN), PP honeycomb compresses thiab rebounds yam tsis muaj kev puas tsuaj mus tas li los yog crumbling.
④ Tshuaj tiv thaiv: PP tiv taus feem ntau cov kua qaub, alkalis, cov kuab tshuaj, thiab cov roj ntawm chav sov - haum rau cov chaw ua tshuaj lom neeg thiab cov rooj tog zaum.
⑤ Lub teeb yuag: ntawm 40-200 kg / m³ ceev, PP honeycomb yog ib qho ntawm cov khoom siv hauv cov khoom siv sib xws. Lub 15mm / 80 kg / m³ core hnyav 1.2 kg / m² - 60% sib dua li plywood thiab 50% sib zog dua aluminium honeycomb.
⑥ Zoo heev acoustic thiab thermal rwb thaiv tsev: kaw -cov qauv ntawm tes muab lub suab nqus (tshwj xeeb tshaj yog nrog perforated facials) thiab thermal rwb thaiv tsev (thermal conductivity ~ 0.04–0.06 W / m·K).
⑦ Recyclable thiab eco- phooj ywg: PP yog 100% recyclable (resin code #5). Sandwich panels nrog PP core thiab PP cov ntsej muag yog mono- cov khoom siv thiab tuaj yeem siv ua ke. Tsis muaj formaldehyde, tsis muaj VOCs.
⑧ Cov txheej txheem yooj yim: PP honeycomb tuaj yeem raug txiav nrog rab riam siv hluav taws xob (cov ntawv nyias), lub voj voog saw, bandsaw, CNC router, waterjet, lossis tuag- cutter. Tsis xav tau cov cuab yeej tshwj xeeb. Ntxuav txiav - tsis muaj plua plav phom sij (tsis zoo li aramid lossis carbon fiber).
⑨ Kev qaug zog zoo: PP honeycomb tuaj yeem rov ua haujlwm tsis tu ncua yam tsis muaj kev ua haujlwm degradation - tseem ceeb rau tsheb thiab thauj hauv pem teb panels.
⑩ Kev hloov pauv tau yooj yim: PP honeycomb muaj cov kev taw qhia yooj yooj yim rau ntawm lub xov tooj ntawm tes, tso cai rau nws ua raws li qhov nruab nrab ib qho - curvature nto yam tsis muaj crushing.

A: Los ntawm cell geometry:
· Hexagonal (tus qauv): lub zog zoo tshaj - rau - qhov hnyav piv, feem ntau, muaj nyob rau hauv 6-20mm cell loj
· Lub voj voog: cov phab ntsa ntawm tes du, qis qis dua kev xaiv, zoo rau lub tshuab nqus tsev
· Rectangular / square: directional zog, siv rau tej yam load
Raws li cov khoom qib:
· Virgin PP: tus qauv zoo, cov khoom siv kho tshuab zoo ib yam - pom zoo rau kev siv cov qauv
· Recycled PP (rPP): tus nqi- siv tau, me ntsis qis dua cov khoom siv kho tshuab - haum rau cov ntawv tsis yog- cov qauv thiab ntim
· iav-fiber reinforced PP (PP-GF): 20-30% siab dua compressive thiab shear zog, txhim kho tshav kub tsis kam - rau tsheb thiab siab- kev ua tau zoo
· Hluav taws kub-retardant PP (FR-PP): halogen-dawb intumescent FR formulation. Ua tau raws li UL94 V-0, FAR 25.853 (12-thib ob ntsug hluav taws kub), thiab DIN 5510. Rau aerospace, rail, thiab pej xeem siv tsev.
· Conductive / anti-static PP: carbon- puv rau ESD tiv thaiv - rau cov khoom siv hluav taws xob ntim khoom thiab cov ntawv thov huv
· UV-stabilized PP: rau kev siv sab nraum zoov nrog lub hnub raug lub hnub ntev
Los ntawm kev kho deg:
· Txheem (tsis kho): haum rau kev sib cuag cov nplaum thiab cov khoom siv sib txuas
· Tsis yog -polyester velvet (surface lev): txhim kho cov nplaum ntub dej- tawm thiab kev sib raug zoo nrog epoxy, PU, ​​thiab lwm yam kua nplaum
· Corona / ntshav kho: txhim kho lub zog saum npoo kom txhim kho cov nplaum nplaum

A: Txheem PP honeycomb yog combustible (UL94 HB ntsuam xyuas) thiab tsim nyog rau daim ntawv thov yam tsis muaj hluav taws kub nruj. Rau cov ntawv thov uas xav tau kev tiv thaiv hluav taws, peb muab:
· Hluav taws kub-retardant PP honeycomb (FR-PP): halogen-dawb, intumescent formulation uas ua tau raws li:
- UL94 V-0 (tus kheej tua hauv 10 vib nas this)
- FAR 25.853 (a) Appendix F Part I (a)(1)(i) - 12-second vertical burn test for aircraft interiors
- DIN 5510 (S4/SR2/ST2) - German rail tsheb txheem
- EN 45545-2 (HL1/HL2) - European rail hluav taws kev nyab xeeb
- GB 8624 Chav B1 (nplaim-} retardant) rau cov khoom siv hauv tsev
Nco tseg: tag nrho qhov ntsuas hluav taws kub ntawm lub vaj huam sib luag tiav yog nyob ntawm ob lub ntsiab lus thiab cov khoom siv. Rau Class A daim ntawv thov, khub FR-PP core nrog tsis yog-combustible faces (aluminium, steel) thiab txheeb xyuas qhov sib dhos los ntawm kev ntsuas hluav taws.

A: · Standard specifications nyob rau hauv Tshuag: 3-7 hnub ua hauj lwm
· Txheem cell / ntom nrog kev cai thickness: 10-15 hnub ua hauj lwm
· FR- qib lossis cov qauv tshwj xeeb: 15–25 hnub ua haujlwm
· Kev cai ntawm tes loj lossis qhov loj loj xaj: ncua sij hawm lees paub rooj plaub-los ntawm- rooj plaub
Ntau lawm muaj peev xwm yog kwv yees li 3,000-5,000 m² ib hnub twg rau tus qauv cores. Peb npaj cov lus qhia nrov (80 kg / m³, 8mm cell, 10-25mm thickness) rau kev xa khoom sai. Rau kev txiav txim kev cai, qhov tseem ceeb hauv cov khoom siv raw khoom thiab cov kab ntau lawm lub sijhawm.

A: Ntim: PP honeycomb core nplooj ntawv yog stacked tiaj tus ntawm pallets, sib cais los ntawm nyias PE zaj duab xis interlayers los tiv thaiv nto marring. Corner tiv thaiv yog siv. Cov pawg yog qhwv rau hauv hnyav- lub luag haujlwm stretch zaj duab xis thiab ruaj nrog polyester strapping. Rau kev xa tawm, pallets raug kaw hauv corrugated cardboard lossis plywood crates.
Shipping:
· Hauv tsev: mob siab rau logistics, qhov rooj - mus rau - qhov rooj
· Thoob ntiaj teb: FCL hiav txwv freight nyiam (PP honeycomb yog bulky vim tsawg ntom - 40HQ thawv tuav kwv yees li 3,000-4,000 m² ntawm 15mm thickness). FOB / CIF nqe lus.
Kev tuav: PP honeycomb yog lub teeb yuag thiab tuaj yeem ua haujlwm ntawm tes. Tsis txhob rub cov nplooj ntawv hla qhov chaw ntxhib; nqa thiab qhov chaw. Khaws cia rau hauv qhov chaw qhuav kom deb ntawm tshav ntuj ncaj qha thiab qhov chaw tshav kub.

A: Vaj huam sib luag ntau lawm txoj kev:
① Adhesive zaj duab xis lamination: qhov chaw thermosetting epoxy lossis polyurethane nplaum zaj duab xis ntawm PP core thiab cov tawv nqaij; kub-nias ntawm 100–150 degree, 0.1–0.5 MPa rau 10–30 feeb. Lub zog zoo tshaj plaws; haum rau txhuas, FRP, thiab plywood faces.
② Cov nplaum nplaum ua kua: siv ob-ib feem PU, epoxy, los yog MS polymer nplaum rau cov tub ntxhais nto nrog cov menyuam coater lossis tshuaj tsuag; nteg ntsej muag; nias ntawm chav tsev kub los yog nruab nrab cua sov. Kev teeb tsa sai dua, tsis tas yuav tsum tau cua sov xovxwm.
③ Kub-melt lamination: polyolefin-raws li kub- yaj zaj duab xis ntawm thermoplastic faces thiab PP core; nruam yob-rau- yob lossis nias lamination ntawm 130-160℃. Tau tshaj PP cov ntsej muag rau 100% rov ua dua mono- cov khoom vaj huam sib luag.
④ Nqus hnab ntim: rau nkhaus lossis zoo li cov vaj huam sib luag - nteg cov nplaum thiab cov ntsej muag hauv lub hnab nqus tsev; siv lub tshuab nqus tsev (-0.8 bar) ntawm chav tsev lossis qhov kub siab.
Cov lus qhia ua haujlwm:
· Txiav: ncig saws (zoo- hniav carbide), bandsaw, CNC router, waterjet, los yog oscillating riam cutter. Txiav ntawm chav sov - kom tsis txhob muaj cua sov uas ua rau cov PP melts.
· Ntug xov: siv ntug sealant (PU lossis epoxy) lossis ntug profile los tiv thaiv cov npoo npoo thiab tiv thaiv kom tsis txhob ya raws (txawm tias PP tsis muaj dej, cov npoo npoo tuaj yeem khaws cov av).
· Drilling thiab fastening: siv threaded inserts los yog rivet ceev rau txhua yam fasteners. Ua ntej- xyaum nrog me ntsis undersized. Los ntawm -bolts nrog loj washers faib load.
· Thermoforming: PP honeycomb tuaj yeem ua tau thermoformed nrog thermoplastic faces rau 3D duab - cua sov rau 150-170 degree, tsim nyob rau hauv ib tug matched pwm, thiab txias nyob rau hauv siab.
Peb muab cov ncauj lus kom ntxaws lamination, cov lus pom zoo ntawm cov nplaum, thiab kev txhawb nqa rau vaj huam sib luag manufacturers.
