Kuaj lub zog ntawm lub zog kub ntawm kub yaj xov yog qhov tseem ceeb rau kev ua yeeb yam ntawm cov qauv sib xyaw (xws li cov xov paj), ncaj qha cuam tshuam cov khoom lag luam durability thiab ua haujlwm. Hauv qab no muaj cov ncauj lus kom ntxaws, cov qauv, thiab kev txiav txim siab:
1. Cov Kev Ntsuas Cov Txheej Txheem
1.1 tev xeem
Daim ntawv thov: Txheeb xyuas cov interfacial bonding lub zog ntawm cov tub ntxhais thiab cov hmoov av (lossis nruab nrog npog txheej thiab cov tub ntxhais).
Tus qauv:
ASTM D1876(T-tev xeem)
ISO 11339(Nplaum nplaum tev lub zog)
Kev ua:
Qauv npaj:
Txiav kub yaj paj rau 25 mm × 150 mm strips (nrog cais cov tub ntxhais thiab sheath).
Clamp ob qho tib si los tsim ib qho "T" duab.

Kuaj mob:
Kub: 23 ± 2 degree, av noo: 50 ± 5% pu.
Lub Tensile Ceev: 100 mm / min (ASTM Txuj).
Cov Ntaub Ntawv Kev Ntsuam Xyuas:
Sau cov quab yuam tshaj plaws (n / cm) thaum lub sij hawm tev; suav qhov nruab nrab tre zog zog.
Hla kev: Feem ntau ntau dua los yog sib npaug rau 5 n / cm (sib txawv los ntawm daim ntawv thov).
1.2 Lap Shak Test
Daim ntawv thov: Ntsuas kev sib txuas lub zog nruab nrab ntawm cov xov paj kub kub thiab lwm yam ntaub ntawv (piv txwv li, ntaub, hlau).
Tus qauv:
ASTM D1002(Hlau-rau-hlau shear lub zog)
GB / T 7124(Suav teb cov qauv)
Kev ua:
Qauv npaj:
Sandwich kub yaj xov ntawm ob substrates (piv txwv li, ntaub / hlau) nrog 25 × 12.5 hli sib tshooj.
Kho nyob rau hauv cov xovxwm kub (kub / sijhawm raws cov khoom).
Kuaj mob:
Tensile Ceev: 1.3 MM / min (ASTM D1002).
Cov Ntaub Ntawv Kev Ntsuam Xyuas:
Xam cov she share zog (mpa)=siab tshaj plaws quab yuam / sib tshooj.
1. {3 180 cov qib tev xeem
Daim ntawv thov: Kev tshuaj xyuas ceev ceev ntawm kev sib koom ua ke ntawm npog fibers thiab cov tub ntxhais.
Kev ua:
Qauv Kho: Tev ib qho kawg ntawm cov yarn kom ua rau cov tub ntxhais; clamp ntawm 180 degree kaum sab xis.
Kev kuaj: Tev ntawm 50 hli / min; sau kev quab yuam-kev nkhaus.
2. Cov Khoom Siv Yuav Tsum Tau
| Cuab tam | Ntsiab lus tseem ceeb | |
|---|---|---|
| UNIVERSAL SEWING TSHUAB | Load ntau {{{{0}}}. 1-5 kn, ± 0.5% tseeb | |
| Kub Xovxwm | Kev tswj qhov kub thiab txias ± 1 degree, 0}}}}}}} - - 10 mpa | |
| Ib puag ncig Chamber | Kub ({-40 degree -150 degree), rh 10-95% |
3.. TSEEM CEEB FEEM & OPPTIZATIZES
Cov khoom siv tau sib xws:
Tsab: Tub ntxhais-txaj-sheather thermal expansion mismatch ua rau muaj kev sib xyaws.
Lus teb: Ntxiv cov malatibilizers (piv txwv li, txiv neej muaj anhydride-grafted polymers).
Txheej txheem tsis:
Tsab: Cov cores kub ntau dhau heev. tsis txaus tshav kub tsis muaj zog ua kom tiav.
Lus teb: Teeb gradient kub raws li MFI (piv txwv li, TPU: 180-220 degree).
Nto Kho:
Tsab: Cov paug (roj, noo noo) txo kev sib raug zoo.
Lus teb: Ua ntej-kho nrog Plasma ntxuav lossis kuab kev so.
4. Kev Lag Luam Cov Qauv Kev Lag Luam
| Daim ntawv thov | Lub hom phiaj | Yuav tsum muaj zog yuav tsum tau ua |
|---|---|---|
| Cov Khaub Ncaws Them Xov Paj | GB / T 3916 | Ntau dua los yog sib npaug rau 4 n / cm (180 degree tev) |
| Muaj Cov Khoom Siv-Shooth Paj | ASTM D7269 | Ntau dua los yog sib npaug rau 8 n / cm (t-tev) |
| Kev Kho Mob Nonwoven npuag | ISO 22610 | Ntau dua los yog sib npaug rau 3 n / cm (ntub peel) |
