Yam tseem ceeb cuam tshuam rau lub tshav kub sealing zoo ntawm retort hnab ntim

Lub tshav kub sealing zoo ntawm cov hnab ntim khoom sib xyaw yeej ib txwm yog ib qho ntawm cov khoom tseem ceeb tshaj plaws rau cov tuam txhab ntim khoom los tswj cov khoom zoo.Cov hauv qab no yog cov yam ntxwv uas cuam tshuam rau cov txheej txheem kub sealing:

1. Hom, thickness thiab zoo ntawm cov khoom siv thaum tshav kub kub-sealing txheej muaj ib tug txiav txim siab ntawm lub tshav kub-sealing zog.Feem ntau siv cov khoom siv hluav taws xob sib khi rau kev ntim khoom suav nrog CPE, CPP, EVA, kub yaj nplaum thiab lwm yam ionic resin co-extruded los yog sib tov hloov cov yeeb yaj kiab.Lub thickness ntawm cov khoom cua sov-sealing txheej feem ntau yog nyob nruab nrab ntawm 20 thiab 80 μm, thiab nyob rau hauv tshwj xeeb, nws muaj peev xwm ncav cuag 100 mus rau 200 μm.Rau tib cov khoom siv thaum tshav kub kub-sealing, nws cov cua sov-sealing zog nce nrog qhov nce ntawm tshav kub-sealing thickness.Thaum tshav kub kub sealing zog ntawm lubretort hnabfeem ntau yuav tsum ncav cuag 40 ~ 50N, yog li lub thickness ntawm cov khoom siv thaum tshav kub kub sealing yuav tsum siab tshaj 60 ~ 80μm.

2. Lub tshav kub sealing kub muaj qhov ncaj qha cuam tshuam rau lub tshav kub sealing lub zog.Lub melting kub ntawm ntau yam ntaub ntawv ncaj qha txiav txim siab qhov zoo ntawm lub hnab composite yam tsawg kawg nkaus kub sealing kub.Nyob rau hauv cov txheej txheem ntau lawm, vim yog lub zog ntawm cov cua sov sealing siab, lub hnab ua kom ceev thiab lub thickness ntawm cov khoom sib xyaw substrate, qhov tseeb kub sealing kub yog feem ntau siab tshaj qhov kub ntawm melting kub ntawm lub tshav kub sealing khoom.Qhov me me ntawm lub tshav kub sealing siab, qhov siab dua qhov yuav tsum tau kub sealing kub;lub tshuab ceev ceev, qhov tuab ntawm cov khoom txheej txheej ntawm cov zaj duab xis sib xyaw, thiab qhov siab dua qhov yuav tsum tau ua kom sov sealing kub.Yog hais tias qhov kub ntawm lub tshav kub-sealing yog qis dua qhov softening point ntawm cov khoom siv thaum tshav kub kub sealing, tsis muaj teeb meem yuav ua rau kom lub siab los yog ntev lub sij hawm kub-sealing, nws yog tsis yooj yim sua kom lub tshav kub-sealing txheej tiag tiag sealing.Txawm li cas los xij, yog tias qhov kub thiab txias sealing siab dhau lawm, nws yooj yim heev rau kev puas tsuaj rau cov khoom siv thaum tshav kub kub sealing ntawm ntug vuam thiab yaj extrusion, uas ua rau qhov tshwm sim ntawm "hauv paus txiav", uas zoo heev txo lub tshav kub sealing lub zog ntawm lub foob thiab qhov cuam tshuam tsis kam ntawm lub hnab.

3. Yuav kom ua tiav qhov zoo tshaj plaws tshav kub sealing lub zog, ib qho kev siab yog qhov tseem ceeb.Rau cov hnab ntim nyias thiab lub teeb, lub tshav kub sealing siab yuav tsum yog tsawg kawg 2kg / cm, thiab nws yuav nce ntxiv nrog rau qhov nce ntawm tag nrho cov thickness ntawm cov zaj duab xis composite. ua tiav qhov tseeb fusion ntawm ob zaj duab xis, uas ua rau cov cua sov hauv zos lub sealing tsis zoo, los yog nws yog ib qho nyuaj rau tshem tawm cov cua npuas uas ntes tau nyob rau hauv nruab nrab ntawm lub vuam, uas ua rau lub vuam virtual; Raws li qhov loj npaum li qhov ua tau, nws yuav tsum tsis txhob ua kom puas lub vuam ntug, vim hais tias ntawm qhov kub thiab txias sealing ntau dua, cov khoom kub-sealing ntawm lub vuam ntug yog twb nyob rau hauv ib nrab-molten lub xeev, thiab lub siab ntau dhau yuav yooj yim nyem tawm ib feem ntawm lub welding ntug. Thaum tshav kub kub-sealing khoom, ua rau lub ntug ntawm lub vuam seam tsim ib nrab-txiav lub xeev, lub vuam seam yog nkig, thiab lub tshav kub-sealing zog yog txo.

4. Lub sij hawm kub-sealing yog tsuas yog txiav txim los ntawm qhov ceev ntawm lub hnab ua tshuab txiav txim siab.Lub sij hawm thaum tshav kub kub sealing kuj yog ib qho tseem ceeb cuam tshuam rau lub sealing lub zog thiab cov tsos ntawm weld.Tib qhov kub thiab txias sealing, lub sij hawm sib khi thaum tshav kub kub yog ntev dua, lub tshav kub sealing txheej yuav ntau dua fused, thiab kev sib xyaw ua ke yuav muaj zog dua, tab sis yog tias lub sijhawm kub sealing ntev dhau lawm, nws yooj yim ua rau vuam seam. kom wrinkle thiab cuam tshuam rau qhov tsos.

5. Yog hais tias lub vuam seam tom qab tshav kub sealing tsis zoo txias, nws yuav tsis tsuas cuam tshuam cov tsos flatness ntawm vuam seam, tab sis kuj muaj qee yam cuam tshuam rau lub tshav kub sealing zog.Cov txheej txheem cua txias yog txheej txheem ntawm kev tshem tawm kev ntxhov siab los ntawm kev tsim cov welded seam tsuas yog tom qab melting thiab kub sealing ntawm qhov kub thiab txias nyob rau hauv ib qho kev siab.Yog li ntawd, yog tias lub siab tsis txaus, cov dej txias ntws tsis zoo, lub voj voog ntim tsis txaus, cov dej kub siab dhau, lossis txias tsis raws sijhawm, qhov txias yuav tsis zoo, cov cua sov sealing ntug yuav yog. warped, thiab lub tshav kub sealing zog yuav raug txo.
.
6. Lub sij hawm ntau ntawm cov cua sov sealing, qhov siab dua qhov kub sealing zog.Tus naj npawb ntawm longitudinal tshav kub sealing nyob ntawm qhov sib piv ntawm qhov zoo ntawm qhov ntev ntawm lub vuam pas nrig mus rau qhov ntev ntawm lub hnab;tus naj npawb ntawm transverse heat sealing yog txiav txim los ntawm tus naj npawb ntawm cov txheej txheem ntawm transverse heat sealing li ntawm lub tshuab.Thaum tshav kub kub sealing zoo yuav tsum muaj tsawg kawg yog ob zaug ntawm cov cua sov sealing.Lub tshuab ua lub hnab dav dav muaj ob txheej ntawm riam kub, thiab qhov siab dua qhov sib tshooj ntawm cov riam kub, qhov zoo dua qhov kub sealing nyhuv.

7. Rau cov zaj duab xis sib xyaw ntawm tib cov qauv thiab tuab, qhov siab dua lub tev lub zog ntawm cov khaubncaws sab nraud povtseg, ntau dua qhov kub sealing zog.Rau cov khoom uas tsis tshua muaj kev sib xyaw tev lub zog, qhov kev puas tsuaj feem ntau yog thawj qhov kev sib txuas ntawm cov yeeb yaj kiab sib xyaw ntawm qhov vuam, ua rau cov txheej txheem kub-sealing ntawm nws tus kheej coj lub zog tensile, thaum cov khoom txheej txheej poob nws cov nyhuv reinforcing, thiab lub tshav kub-sealing ntawm lub weld Lub zog yog li no zoo heev txo.Yog hais tias qhov sib xyaw tev lub zog loj, lub interlayer tev ntawm lub vuam ntug yuav tsis tshwm sim, thiab ntsuas qhov ntsuas kub lub zog yog qhov loj dua.
