Muab tso rau hauv lub tshav kub sealer rau cua sov sealing. Thaum tshav kub kub sealing tej yam kev mob yog: Kub 155 ° C ± 5 ° C, siab 0.2 Mpa, sij hawm 1 thib ob. Tom qab cua sov sealing, tshem tawm thiab cia nws txias. Txiav nws rau hauv 15mm dav qauv. Thaum tshav kub kub foob lub zog ntsuas txoj kev (YBB00122003-2015), Kev ntsuas ceev yog 200mm / min ± 200mm / min, cov PVC (lossis PVDC) daim ntawv yog clamped rau sab sauv clamp ntawm lub tshuab kuaj, thiab cov ntawv txhuas txhuas yog clamped rau hauv qis clamp ntawm lub tshuab kuaj. Pib lub tshuab ntsuas tensile kom tev ntawm lub kaum sab xis ntawm 180 °, thiab qhov nruab nrab kub sealing lub zog yuav tsum tsis txhob qis dua 7.0N / 15mm (PVC); tsis qis dua 6.0N / 15mm (PVDC).

[Kev Tiv Thaiv Txheej Adhesiveness] Nqa ib qho qauv nrog qhov ntev 90 mm ntev thiab dav dav (nco ntsoov tias tus qauv yuav tsum tsis txhob muaj wrinkles). Muab cov qauv tso rau ntawm lub iav phaj nrog cov txheej tiv thaiv, nqa ib daim ntaub nplaum polyester (nrog lub zog tev ntawm tsis pub tsawg dua 2.94N / 20mm los ntawm aluminium ntawv ci), thiab nias nws tusyees rau saum npoo ntawm tus qauv horizontally ntawm lub siab ntawm 160-180. Kev taw qhia peels tawm sai sai
Yuav tsum tsis muaj qhov pom tseeb tev tawm ntawm qhov chaw tiv thaiv txheej.

[Thaum tshav kub kub tsis kam ntawm cov txheej txheem tiv thaiv] Noj 3 daim ntawm cov khoom no ntawm 100mm / 100mm, raws li laminate tiv thaiv txheej ntawm cov qauv nrog thawj aluminium ntawv ci, muab tso rau ntawm lub tshav kub sealer, thiab cua sov foob nws. Thaum tshav kub kub sealing tej yam kev mob: kub 200 ° C, siab 0.2 Mpa, sij hawm 1 thib ob, tshem nws tawm thiab cia nws txias rau chav sov, cais cov qauv los ntawm thawj aluminium ntawv ci, saib xyuas qhov kub tsis kam ntawm txheej tiv thaiv, yuav tsum tsis muaj qhov pom tseeb lo rau ntawm qhov chaw tiv thaiv.

[Adhesive daim ntaub qhov sib txawv] Noj 5 daim ntawm cov khoom no ntawm 100mm × 100mm, thiab ntsuas lawv kom raug (m 1), so tawm cov nplaum nrog ethyl acetate lossis lwm cov kuab tshuaj, thiab hnyav lawv dua (m2)
Qhov sib txawv ntawm m1 thiab m2 yog txheej txheej ntawm cov nplaum. Tib lub sijhawm, xam tus nqi nruab nrab ntawm cov txheej txheej ntawm 5 smears. Qhov sib txawv ntawm txheej txheej ntawm txhua daim thiab qhov nruab nrab tus nqi yuav tsum nyob rau hauv ± 10.0%.

[Unwinding kev ua tau zoo] Noj 4 daim ntawm cov khoom no ntawm 100mm × 100mm, superimpose cov qauv nplaum txheej thiab tiv thaiv txheej, muab tso rau ntawm ib lub phaj tiaj tus uas tsim nyog, tso ib lub phaj me me ntawm 20mm × 20mm thiab qhov hnyav ntawm 1.0kg ntawm tus qauv tig, Tom qab 2 teev nyob rau hauv qhov cub ntawm 40 ° C, coj nws tawm thiab saib xyuas tias cov nplaum nplaum thiab cov txheej tiv thaiv tsis tuaj yeem sib txuas.

【Bursting Strength】 Coj 3 daim ntawm cov khoom no ntawm 40mm × 40mm, thiab muab lawv tso rau ntawm lub ntsuas hluav taws xob tawg los ntsuas lawv raws, thiab tag nrho lawv yuav tsum tsis txhob qis dua 98kPa.
