Hauv kev lag luam ntim khoom, kev xaiv cov txheej txheem sealing ncaj qha cuam tshuam rau cov khoom tiv thaiv kev ua haujlwm, kev ua haujlwm ntau lawm, thiab kev ua lag luam yoog raws. Induction sealing, raws li qhov tsis yog -kev sib txuas tshuab raws li electromagnetic induction cua sov, txawv qhov sib txawv ntawm cov txheej txheem sealing ib txwm muaj thiab zoo sib xws hauv cov ntsiab lus, cov xwm txheej, thiab kev ua haujlwm zoo. Kev nkag siab txog qhov sib txawv no pab cov tuam txhab ua cov kev xaiv thev naus laus zis ntau dua hauv kev tsim tawm.
Piv rau thermoforming sealing, qhov sib txawv loj tshaj plaws hauv induction sealing yog nyob rau hauv txoj kev cua sov. Thermoforming sealing cia siab rau lub phaj cua sov los yog cov menyuam ncaj qha hu rau lub thawv qhib thiab cov khoom sib khi, ua tiav cov melting thiab kev sib txuas los ntawm kev siv hluav taws xob. Txoj kev no yog qhov ua rau tsis sib npaug ntawm qhov sib khi vim qhov sib cuag tsis sib xws los yog ncua kev hloov mus rau cov cua sov, thiab tej zaum yuav ua rau puas tsuaj ntawm cov cua sov- cov thawv ntim khoom. Induction sealing, ntawm qhov tod tes, siv lub siab - zaus alternating magnetic teb los tsim eddy tam sim no nyob rau hauv cov hlau induction txheej, sai cua sov kom ua tau lub zos, ceev, thiab uniform kub melting. Nws tsis ncaj qha hu rau lub thawv, zam kev hnav khaub ncaws thiab txo qhov deformation tshwm sim los ntawm tshav kub diffusion, ua rau nws haum rau siab - kub rhiab ntim ntim los yog ntim nrog cov kev xav tau zoo saum npoo.
Piv rau ultrasonic sealing, txawm hais tias ob qho tib si tsis yog -hu rau thermal zog daim ntawv thov, lawv cov txheej txheem sib txawv. Ultrasonic sealing cia siab rau siab -frequency mechanical vibration to generate frictional heat at the interface, softening and bonding the material. Nws yog qhov tsim nyog rau vuam cov thermoplastics, tab sis tawm tsam los tsim cov kev sib khi zoo ntawm cov hlau lossis cov yeeb yaj kiab sib xyaw uas muaj cov txheej txheem hlau, thiab nws qhov sib xws yog txwv nyob rau hauv ntau- cov txheej txheem sib xyaw lossis cov npoo nkhaus. Induction sealing, ntawm qhov tod tes, ua ncaj qha rau ntawm cov txheej txheem hlau, tsis txwv los ntawm cov khoom ntim khoom (nws tuaj yeem ua haujlwm nrog cov yas, iav, hlau, thiab lwm yam), thiab tuav ruaj khov airtightness thiab watertightness nyob rau hauv complex duab thiab siab -ceev ntau lawm kab.
Piv rau kev sib khi txias (adhesive sealing), uas tso siab rau cov nplaum kho ntawm chav tsev lossis qhov kub qis yam tsis muaj qhov cua sov, ua rau nws tsim nyog rau cov cua sov- cov ntsiab lus rhiab heev, txias sealing feem ntau muaj qhov cuam tshuam qis dua li cov cua sov- sealing, yog qhov cuam tshuam rau degradation vim qhov kub thiab txias thiab cov av noo. Induction sealing, los ntawm tshav kub- melted integrated sealing txheej, muaj superior barrier zog, muaj zog tiv thaiv oxidation, noo noo, thiab tampering, ua tshwj xeeb tshaj yog haum rau export cov khoom uas yuav tsum tau ntev - nyob rau hauv hiav txwv thauj los yog ntev - lub sij hawm cia.
Tsis tas li ntawd, piv rau nplaim hluav taws xob los yog laser sealing, induction sealing muaj qhov zoo ntawm kev siv hluav taws xob thiab kev nyab xeeb. Nplaim sealing yog lub zog- hnyav thiab ua rau muaj kev nyab xeeb vim muaj nplaim taws qhib. Cov khoom siv laser sealing yog kim thiab muaj cov kev cai tshwj xeeb hais txog cov khoom siv lub teeb xa hluav taws xob. Hauv qhov sib piv, induction sealing muaj lub zog muaj zog, lub sijhawm cua sov luv, thiab lub tshav kub me me- cuam tshuam, ua rau nws yooj yim rau automate thiab scale li ntau lawm.
Hauv cov ntsiab lus, induction sealing, nrog nws qhov zoo sib xws xws li tsis yog -cov cua sov, cov khoom siv dav siv tau, kev ua haujlwm siab thiab ruaj khov, thiab kev sib khi zoo dua, ua kom pom tseeb tus nqi ntawm kev ua kom zoo ntawm cov khoom ntim, txhim kho kev tsim khoom, thiab txo cov nqi tag nrho, ua rau nws nyiam sealing kev daws teeb meem rau ntau cov khoom lag luam siab {1}.
