1. Hom Tsev
| Ntaus | Ntaub ntawv | Qhov Zoo | Tsis zoo |
|---|---|---|---|
| Yas (PBT / PA66) | Polybutylene Terephthalate (PBT), Nylon (PA66) | Lub teeb yuag, raug nqi tsim nyog, corrosion-resistant, zoo hluav taws xob rwb thaiv tsev. | Txo cov tshuab hluav taws xob muaj zog, tsawg kub tiv taus (~ 120 degree). |
| Hlau (Aluminium / Stainless Hlau) | Aluminium Alloy, Hlau Stainless | Zoo tshaj emi / RFI kev tiv thaiv, muaj siab ruaj khov, cua sov dissipation, fireproof. | Hnyav, kim, yuav tsum tau av kom tsis txhob muaj kev cuam tshuam lub suab. |
| Thermoplastic roj hmab (TPE / TPU) | Thermoplastic elastomer (TPE), Polyurethane (TPU) | Saj zawg zog, kev co-dampening, IP 67+ dej. | Tsis tshua muaj zog, yuav txwv tsis pub dhau UV / tshuaj lom neeg raug. |
| Silicone | Silicone Roj Hmab | Extreme temperature resistance (-60 degree to +200 degree ), soft sealing. | Tsawg dua kua muag lub zog, tsis zoo ua rau tsis taus. |
| Daim Ntawv Sib Sau (Fiberglass-Refinced) | Fiberglass + Epoxy Resin | Siab zog-rau-hnyav piv, tshuaj / UV resistant. | Nkig nyob rau hauv kev cuam tshuam, cov txheej txheem moulding nyuaj. |
2. Cov Qauv Xaiv Yuam Kev
1) Kev xav tau ib puag ncig:
IP RATION: Xaiv IP67 / IP68 rau kev ua dej tsis huv (piv txwv li, gaske gaskets).
Kev Tiv Thaiv EMI: Cov tsev hlau lossis daim thaiv npog plastics (piv txwv li, PBT nrog cov khoom sib tw).
2) Kev Nyuaj Siab Kev Nyuaj Siab:
Siv hlau / sib xyaw rau cov chaw co / cuam tshuam (piv txwv li, automotive, aerospace).
TPE / TPU rau kev hloov pauv cable yoog.
3) Kub:
Silicone/metal for extreme heat (>150 degree) lossis cryogenic ib puag ncig.
4) nqi vs. Lifespan:
Plastics rau cov khoom siv nyiaj txiag; Hlau rau kev ntseeg tau ntev.
3. Ntxiv kev tiv thaiv txoj kev
1) Qhaus nyem:
Plab hlaub los yog overmolding los tiv thaiv cable rub-tawm.
2) conformal txheej:
Acrylic / silicone Spps rau kev tiv thaiv PCB-qib noo noo.
3) Cov tsho tiv no braided:
Stainless hlau / Tsiaj Braips rau absunt tsis kam.
4. Cov ntsiab lus tsis ua haujlwm & kev txo qis
| Tsab | Lus teb |
|---|---|
| Tshuaj Nyab Xeeb | Siv dual-txheej ntsaws ruaj ruaj (o-rings + potting). |
| EMI Kev cuam tshuam | Cov tsev nyob hauv av; Ntxiv cov cores ferrite. |
| Kev co rog | Txais cov xov tooj / txhav tas txuas (piv txwv li, m12 ntsia hlau-hom). |
| Uv Kev Ruaj Ntseg | Xaiv UV-ruaj ruaj cov ntaub ntawv (piv txwv li, dub pa66). |
5. Cov piv txwv kev lag luam tshwj xeeb
1) Automotive:
PA66 Housings + IP6K9K (Kev ntxuav siab ntxuav tawm).
2) Aerospace:
Aluminium vaj tse nrog mil-dtl -38999 specs.
3) Tubrog Nkoj:
Stainless hlau + silicone sealts (ntsev corrosion tiv thaiv).
Lub ntsiab
Xaiv cov tsev raws li kev ntxhov siab ib puag ncig, EMI xav tau, thiab tus nqi. Rau cov mob hnyav, cov hlau ua ntej lossis sib sau ua ke; Rau kev yoog tau, tpu / silicone ua haujlwm zoo tshaj plaws. Ib txwm siv tau tawm tsam kev lag luam cov qauv (piv txwv li, ul94 cov nplaim taws, IEC 60529 IP kev ntaus nqi).
