Daya shine zafin hatimin thermal yana da mafi girman tasiri kai tsaye akan ƙarfin rufewar thermal.
Zazzabi na narkewar kayan daban-daban kai tsaye yana ƙayyade mafi ƙarancin zafin hatimin thermal na jakar haɗin gwiwa.A cikin samar da tsari, saboda thermal sealing matsa lamba, da jakar yin gudun da kuma kauri na composite substrate, ainihin thermal sealing zafin jiki ne sau da yawa mafi girma fiye da narkewa zafin jiki na zafi sealing abu.Ƙananan matsi na thermal sealing, mafi girma da zafin jiki na thermal;da sauri da sauri, da kauri abu na hada fim, mafi girma da ake bukata thermal seal zafin jiki.Idan zafin hatimin thermal ya yi ƙasa da wurin laushi na kayan hatimin thermal, ba zai yuwu a haƙiƙa da gaske a rufe Layer ɗin thermal ba komai yadda za a ƙara matsa lamba ko tsawaita lokacin rufewar thermal.Duk da haka, idan zafi sealing zafin jiki ne ma high, yana da sauki lalata narkakkar extrusion na zafi sealing abu a waldi gefen, sakamakon a cikin sabon abu na "tushen yankan", wanda ƙwarai rage zafi sealing ƙarfi na hatimi da kuma. tasirin juriya na jaka.
Na biyu, nau'in, kauri da ingancin kayan aikin rufewar thermal suna da tasiri mai mahimmanci akan ƙarfin rufewar thermal.
Abubuwan da aka saba amfani da su don marufi masu haɗaka sune CPE, CPP, EVA, narke mai zafi da wasu sauran haɗin gwiwar guduro na ionic ko gauraye da aka gyara.A kauri na thermal sealing Layer abu ne kullum tsakanin 20 da 80 μm, kuma a cikin musamman lokuta, har zuwa 100 ~ 200 μm.Irin thermal sealing abu, da thermal sealing ƙarfi ƙara da karuwa da thermal sealing kauri.Ƙarfin rufewa mai zafi na jakar dafa abinci ana buƙatar gabaɗaya don isa 40 ~ 50 Newton, don haka kauri na kayan rufewa mai zafi ya kamata ya zama fiye da 60 ~ 80 μ m.
Na uku, don cimma madaidaicin ƙarfin hatimin zafi, wani matsa lamba yana da mahimmanci.
Don jakunkuna marufi da haske, matsa lamba na thermal ya kamata ya kai aƙalla 2kg / cm2, kuma ya karu daidai da haɓakar jimlar kauri na fim ɗin.Idan matsi na zafin zafi bai isa ba, yana da wuya a cimma ainihin haɗin tsakanin fina-finai biyu, haifar da rufewar zafi na gida ba shi da kyau, ko kuma yana da wuya a kama kumfa a tsakiyar walda, yana haifar da walƙiya;ba shakka, mafi girma da zafi sealing matsa lamba ne ba mafi alhẽri, da zafi ya kamata ya dace kada ya lalata waldi gefen, saboda zafi sealing abu a kan waldi gefen ne a cikin wani Semi-narkakkar jihar, da yawa matsa lamba ne mai sauki matsi. tafi wani ɓangare na zafi sealing abu, sabõda haka, weld gefen samar da wani Semi-yanke jihar, da weld kabu ne gaggautsa, da zafi sealing ƙarfi da aka rage.
Na hudu, idan walda bayan zafi mai zafi ba a sanyaya da kyau ba, ba kawai zai shafi bayyanar da flatness na weld ba, amma kuma yana da wani tasiri akan ƙarfin rufewar zafi.
Tsarin sanyaya shine don kawar da tsarin tattarawar damuwa ta hanyar siffata kawai narkakken zafi mai rufe walda a ƙaramin zafin jiki ƙarƙashin wani matsi.Saboda haka, matsa lamba bai isa ba, sanyaya ruwa wurare dabam dabam ba santsi, wurare dabam dabam adadin bai isa ba, da ruwa zafin jiki ne ma high, ko sanyaya ba dace ba zai kai ga matalauta sanyaya, zafi sealing gefen yana warping, kuma ƙarfin rufewar zafi yana raguwa.
Na biyar, lokacin rufewa mai zafi yana ƙayyade saurin injin yin jaka.
Lokacin rufewar thermal shima muhimmin abu ne da ke shafar ƙarfi da bayyanar hatimin walda.Haka zafi sealing zafin jiki da kuma matsa lamba, da zafi sealing lokaci ne mai tsawo, da zafi sealing Layer Fusion ne mafi cikakken, da hade ne mafi m, amma zafi sealing lokaci ya yi tsayi da yawa, sauki sa weld alagammana, shafi bayyanar.
Na shida, mafi yawan lokutan rufewar zafi, mafi girman ƙarfin rufewar zafi.
Yawan a tsaye thermal sealing ya dogara da rabo daga tasiri tsawon da kuma tsawon jakar, da kuma a tsaye thermal sealing tsawon an ƙaddara da adadin sets na transverse thermal sealing naúrar.Kyakkyawan rufewa mai zafi, yana buƙatar adadin lokutan rufewa mai zafi aƙalla sau biyu.Akwai ƙungiyoyi biyu na wuka mai zafi a cikin injin yin jaka na gabaɗaya, kuma mafi girman haɗin wuka mai zafi, mafi kyawun tasirin rufewa mai zafi.
A ƙarshe, fim ɗin da aka haɗa tare da tsari iri ɗaya da kauri, mafi girman ƙarfin cirewa na ƙirar haɗin gwiwa, mafi girman ƙarfin rufewar thermal.
Don samfuran da ke da ƙaramin ƙarfi na tsiro, gazawar weld galibi shine farkon cirewar fim ɗin a cikin kabu na weld, wanda ke haifar da Layer ɗin hatimin thermal na ciki da kansa yana ɗaukar ƙarfi mai lalata, kuma kayan saman saman yana rasa tasirin ƙarfafawa. , don haka thermal sealing ƙarfi na weld ne ƙwarai rage.Idan ƙarfin tsiri da aka haɗa yana da girma, ɓangarorin tsaka-tsakin ba zai faru ba, kuma ainihin ƙarfin rufewar zafi da aka auna ya fi girma.
