Sezvo nguva yechando ichisvika, tembiricha inodzikira nekudzikira, uye mamwe matambudziko emuchando anosanganisirwa anochinjika ekurongedza ave kuwedzera mukurumbira, senge.NY/PE masaga akabikwauyeNY/CPP retort mabhegiizvo zvakaoma uye brittle; iyo yekunamatira ine yakaderera yekutanga tack; uye chimiro chakaumbwa chechigadzirwa Matambudziko akadai sekusiyana.
01 Iyo yekunamatira ine yakaderera yekutanga tack
Sezvo tembiricha munzvimbo dzakasiyana dzadzika,vamwe vatengi vakashuma kuti simba rekutanga rekubatana kwepamusoro-tembiricha yekubika glue UF-818A/UK-5000 yadzikira pakugadzira PET/AL/RCPP zvimiro, zvinoreva kuti kusimba kweiyo yekunze kwemukati kwakanaka, asi kusimba kweiyo yemukati layer yakadzikira zvakanyanya. Asi mushure mekuiisa muimba yekukwegura kwemaminitsi gumi, pakarepo inowana simba rakanaka. Mutengi anga achishandisa chigadzirwa ichi kweanopfuura hafu yegore uye chave chakanyatsogadzikana, uye ikozvino inoumbwa maitiro haina kuchinja kubva kune yekutanga.
Mushure mekutarisa panzvimbo, zvakaonekwa kuti kunetsa kwezvinhu kwakajairika uye huwandu hweglue hwakaiswa hwasvika 3.7 ~ 3.8g / m2, uye pakanga pasina matambudziko. Zvisinei, apo chikwata chinoputika chakasangana nefirimu, zvakaonekwa kuti firimu haina kunzwa kudziya zvachose, uye kunyange kunzwa kutonhora. Tichitarisa pazvirongwa zveparameter yecomposite roller unit, tembiricha yeroller inoumbwa i50 ° C uye iyo composite pressure ndeye 0.3MPa. Mushure melaminating roller tembiricha yakasimudzwa kusvika 70 ° C uye iyo laminating pressure yakasimudzwa kusvika 0.4Mpa, yekutanga kusungirira simba yakagadziridzwa zvakanyanya, uye kuumbwa kwechimiro kwakagadziridzwa zvakare.
Mutengi akazviona zvisinganzwisisike: iwo maviri ma paramita e laminating roller tembiricha 50 ℃ uye laminating pressure 0.3Mpa yakashandiswa kare, uye hapana mamiriro akadai akamboitika. Nei tichifanira kuchinja iye zvino?
Ngatitangei nekuongororwa kwekumanikidza kwemubatanidzwa: Munguva yekuoma kwekumisa, iyo inosanganiswa kumanikidza pane yega yega gadziriso pepa uye yakaoma lamination muchina inoratidzwa mubha kana MPa, kazhinji 3bar kana 0.3 ~ 0.6MPa. Kukosha uku kwakangofanana neKudzvanywa kwecylinder yakabatana nerubber roller. Muchokwadi, iyo composite kumanikidza kunofanirwa kuve kudzvanywa pane yakatsikirirwa zvinhu pakati peiyo composite pressure roller uye composite simbi roller. Uku kukosha kwekumanikidza kunofanirwa kuve kgf/m kana kgf/cm, ndiko kuti, kudzvanywa pakureba kweyuniti. Kureva, F = 2K * P * S / L ( K ndiyo proportional coefficient, iyo inoenderana necylinder pressure method. Iyo yakananga pressure type ndeye 1, uye mhando yelever yakakura kupfuura 1, iyo inoenderana nereshiyo. yesimba resimba reruoko uye ruoko rwekupikisa P ndiyo cylinder nharaunda; Nekuti saizi yehumburumbira yemichina yakasiyana yakasiyana uye nzira dzekumanikidza dzekushandisa dzakasiyana, kana hunhu hunoratidzwa pamajeji ekumanikidza emichina akasiyana akafanana, kudzvanywa chaiko hakufanire kunge kwakafanana.
Ngatitarisei tembiricha yelamination: Mukuoma kwelamination, mushure mekunamira kwabuda mugero rekuomeswa, iyo solvent yakanyatsobuda, ichisiya chete glue yakaoma. Izvi zvinodaro nekuti iyo yakaoma kushandisa zvakare polyurethane adhesive inorasikirwa neviscosity pakamuri tembiricha mushure mekuoma.Kuti ma substrates maviri aenderane pamwe chete zvakanaka, chinonamira chinofanira kumisa kunamatira kwayo. Naizvozvo, kana laminating, iyo laminating roller inofanira kupiswa kuitira kuti tembiricha yaro yepamusoro iite kuti kunamira kuite activated viscosity.
Mushure mekupinda munaNovember, tembiricha yakadzikira zvakanyanya mune dzimwe nzvimbo. Mukupera kwaNovember, kune dzimwe nzvimbo tembiricha yaingosvika 10°C. Kana vatengi vabatanidza RCPP, zvigadzirwa zvinodhonzwa zvakananga kubva mudura kuenda kumusangano wekugadzira wekugadzira. Panguva ino, tembiricha yeRCPP yakaderera zvakanyanya. Yakabatana nekushisa kwakadzika kwelamination, iyo firimu inopisa kwenguva pfupi panguva yelamination, uye kupisa kwese kwemusanganiswa firimu kwakaderera zvikuru. Huremu hwema molecular huremu hwepamusoro-tembiricha yekubika glue yakakura uye inoda kupiswa kuti isimudzire basa rekunamatira. Kana kutonhora kwakanyanya kuderera, simba rekutanga rekubatanidza richaderedzwa zvakanyanya. Mushure mekuiswa muimba yekuporesa, basa rekunamatira rinokurudzirwa uye simba rinogona kuwedzerwa pakarepo.
Saka, patakawedzera tembiricha yekusanganisa uye kumanikidza kwekuwedzera, dambudziko iri rakagadziriswa.
Rimwe dambudziko rinogona kusangana kana tembiricha yefirimu yakadzikira nderekuti mutsauko wekushisa pakati pemukati nekunze kwewekishopu wakakura, uye musangano wekudhinda unonyorovesa, kana firimu ravhurwa, mhute yemvura inodzika, uye pamusoro. yefirimu ichava nekunzwa kwakanyorova, izvo zvichakanganisa kuonekwa kwechigadzirwa mushure mekukwegura. uye kusimba kunokonzera njodzi huru dzakavanzwa. Pamusoro pezvo, nekuda kwekusagadzikana kwakadzika kunokonzerwa nekudzikira kwekushisa kana chinonamira chikashandiswa, matambudziko ekuonekwa anoitikawo nguva nenguva.
Matanho ekudzivirira:Munguva yechando, zvigadzirwa uye zvinonamira zvinofanirwa kuiswa mumusangano wekugadzira maawa makumi maviri nemana pachine nguva sezvazvinogona. Vatengi vane mamiriro ezvinhu vanogona kuvaka pre-greenhouse. Kunyatso wedzera tembiricha uye kumanikidzwa lamination roller kuona kuti firimu "inodziya" pashure lamination uye mhepo.
02 Bhegi rekudzoreredza rakaomarara uye rakaputsika
Nekusvika kwechando, NY/PE masaga akabikwa uye NY/CPP retort mabhegi anova akaoma uye brittle. Dambudziko rinoguma nderekuti chiyero chekuputsika kwebhegi chinowedzera. Iri rave dambudziko renguva refu muindasitiri yese. Mabhizinesi mazhinji akakura ekurongedza ari kunetsekawo nedambudziko iri uye ari kutsvaga mhinduro.
NY/CPP yakakwira tembiricha inodzivirira mabhegi ekudzoreredza kazhinji anoreva mabhegi akaumbwa anogona kuvharirwa pa121°C kweanopfuura maminetsi makumi matatu. Rudzi urwu rwekurongedza rune kujeka kwakanaka, kusimba kwepamusoro, uye rinoshandiswa zvakanyanya. Mabhegi eNY/PE anowanzo shandiswa kubikira uye mabhegi ekutsvaira nekuda kwesimba rawo rakakwirira uye kusimba kwakanaka.Zvisinei, rudzi urwu rwemabhegi ekuputira ane olefin sechisimbiso chemukati chisimbiso nguva dzose chinotarisana nematambudziko maviri makuru: kutanga, muchando chakanyanya kutonhora, brittleness yehomwe inowedzera, uye kuwedzera kwebhegi kunowedzera; chechipiri, mushure mekubika kana kubika, bhegi rinova rakaoma uye brittleness inowedzera.
Kazhinji kutaura, iyo yemukati layer zvinhu zveakakwira-tembiricha retort mabhegi anonyanya RCPP. Mukana mukuru weRCPP nderekuti ine pachena uye inokwanisa kushingirira kutonhora kwakanyanya kuri pamusoro pe121°C. Izvo zvakashata ndezvekuti yakaoma uye yakanyanya brittle kupfuura zvimwe kupisa seal seal layer. Izvi ndezvechokwadi kunyanya munzvimbo dzakaderera tembiricha.RCPP yakakamurwa kuita zvekumba uye kunze kwenyika. Zvinonzwisisika kuti zvigadzirwa zvemumba zvinonyanya kuita homopolymerized, uye hongu mamwe makambani ari kuita shanduko yeRCPP. Inotengeswa kunze kwenyika RCPP inonyanya kuvharika-yakavakirwa, uye iyo yakanyanya-tembiricha kuramba yehomopolymer yakanyanya kuipa kupfuura iyo yebhuroko. Homopolymer RCPP ichaitwa denatured mushure mepamusoro-tembiricha sterilization, kureva, RCPP ichave yakaoma uye brittle, nepo block RCPP ichiri kuchengetedzwa isati yaitwa sterilization. zvekupfava.
Parizvino, Japan ndiyo iri pamberi pakutsvagisa pasi rose pamusoro pe polyolefins. Mapolyolefin ekuJapan anotumirwawo kupasi rese. Iko kupfava uye kuita kwese kweiyo NY/PE firimu uye yakakwirira-tembiricha yekubika RCPP firimu zvakanaka kwazvo.
Naizvozvo, ini pachangu ndinotenda kuti polyolefin zvinhu zvinoita basa rakakosha mudambudziko rekuomarara uye brittleness yeNY/PE yakabikwa masaga uye NY/CPP retort mabhegi munguva yechando. Pamusoro pezvo, pamusoro pekukanganisa kwezvinhu zvepololefin, ingi uye zvinomisikidza zvinomisikidza zvinewo zvimwe zvazvinoita, uye zvinoda kurongeka kuti pakupedzisira zvibudise mabhegi ekubikira emhando yepamusoro uye anopisa.
Nguva yechando ine mhedzisiro yakawanda pane extrusion lamination, pakati peiyo kugadziriswa kwemhepo gap kwakakosha, uye munhu wese anofanira kuiteerera.
