Pfupiso: Pepa iri rinoongorora dambudziko rema "white point" emafirimu ePET/VMCPP nePET/VMPET/PE paanosanganiswa, uye rinopa mhinduro dzinoenderana.
Firimu rine jira rakagadzirwa nearuminiyamu chinhu chakapfava chekurongedza chine "aluminium luster" inoumbwa nemafirimu akabatanidzwa ane aluminium coated (kazhinji VMPET/VMBOPP, VMCPP/VMPE, nezvimwewo, pakati pazvo VMPET neVMCPP ndizvo zvinonyanya kushandiswa) nemafirimu epurasitiki anoonekera. Rinoshandiswa pakurongedza chikafu, zvigadzirwa zvehutano, zvizoro, nezvimwe zvigadzirwa. Nekuda kwekupenya kwayo kwesimbi, nyore, kukwanisika kutenga, uye kushanda zvakanaka kwezvidziviriro, rave richishandiswa zvakanyanya (hunhu hwaro hwezvidziviriro huri nani pane mafirimu epurasitiki, rakachipa uye rakareruka pane mafirimu epurasitiki ane jira rakagadzirwa nearuminiyamu). Zvisinei, mavara machena anowanzoonekwa panguva yekugadzira mafirimu emhando yearuminiyamu akafukidzwa. Izvi zvinonyanya kuoneka muzvigadzirwa zvemafirimu ane PET/VMCPP uye PET/VMPET/PE.
1. Zvinokonzera uye mhinduro dze "mavara machena"
Tsananguro yechiitiko che "doti jena": Pane madoti machena ari pachena pakuonekwa kwefirimu rakagadzirwa, anogona kuparadzirwa zvisina kurongeka uye ane saizi yakafanana. Kunyanya kune mafirimu akagadzirwa zvisina kudhindwa uye mafirimu einki chena yakazara kana mafirimu einki ane ruvara rwakajeka, zviri pachena.
1.1 Kusakwana kwekusimba kwepamusoro padivi realuminium plating realuminium coating.
Kazhinji, kuyedzwa kwekusimba kwemusoro kunofanirwa kuitwa pamusoro pe corona yefirimu inoshandiswa isati yagadzirwa, asi dzimwe nguva kuyedzwa kwe aluminium coating hakutariswe. Kunyanya kumafirimu eVMCPP, nekuda kwekugona kunaya kwe diki diki dzemamorekuru mufirimu yeCPP base, pamusoro pe aluminium plated yemafirimu eVMCPP akachengetwa kwenguva yakati haakwanise kusimba zvakakwana.
1.2 Kusawirirana zvakanaka kwenamira
Zvinonamira zvine chekuita nekunyungudutsa zvinofanirwa kusarudza huwandu hwakanyanya hwemhinduro inoshanda zvichienderana nebhuku rekushandisa kuti zvive nechokwadi chekuti glue iri kuenzana zvakanaka. Uye kudzora kuyedza viscosity kunofanirwa kuitwa panguva yekugadzira inoenderera mberi. Kana viscosity ikawedzera zvakanyanya, zvinonamira zvinofanirwa kuwedzerwa nekukasika. Makambani ane mamiriro ezvinhu anogona kusarudza michina yeglue yepombi otomatiki yakavharirwa. Tembiricha yakanakisa yekupisa yezvinonamira zvisina solvent inofanira kusarudzwa zvichienderana nebhuku rekushandisa. Pamusoro pezvo, tichifunga nezvenyaya yenguva yekushanda isina solvent, mushure menguva yakareba, glue iri muroller yekuyera inofanira kuburitswa nenguva.
1.3 Maitiro asina kunaka ekubatanidza zvinhu
Kune PET/VMCPP structures, nekuda kwekukora kudiki uye nyore kuwedzera kweVMCPP film, lamination roller pressure haifanirwe kunge yakanyanya kukwira panguva yelamination, uye winding tension haifanirwe kunge yakanyanya kukwira. Zvisinei, kana PET/VMCPP structure iri composite, nekuda kwekuti PET film iri rigid film, zvinokurudzirwa kuwedzera laminating roller pressure uye winding tension zvakakodzera panguva ye composite.
Magadzirirwo anoenderana ekugadzirisa zvinhu anofanirwa kugadzirwa zvichienderana nemamiriro emidziyo yekubatanidza zvinhu kana zvivakwa zvakasiyana zvealuminium coating zvakasanganiswa.
1.4 Zvinhu zvekunze zvinopinda mufirimu rakagadzirwa zvichikonzera "mavara machena"
Zvinhu zvekunze zvinosanganisira guruva, zvidimbu zverabha, kana marara. Guruva nemarara zvinonyanya kubva muworkshop, uye zvinowanzoitika kana hutsanana hweworkshop husina kunaka. Zvikamu zverabha zvinonyanya kubva muma disc erabha, ma coating roller, kana ma bonding rollers. Kana plant ye composite isiri workshop isina guruva, inofanirawo kuedza kuona kuti workshop ye composite yakachena uye yakacheneswa, kuisa michina yekubvisa guruva kana kusefa (coating device, guide roller, bonding device nezvimwe zvikamu) zvekuchenesa. Kunyanya coating roller, scraper, flattening roller, nezvimwewo zvinofanirwa kucheneswa nguva nenguva.
1.5 Hunyoro hwakawanda muworkshop yekugadzira hunoita kuti pave ne "mavara machena"
Kunyanya munguva yemvura, apo hunyoro hwemuworkshop huri ≥ 80%, firimu recomposite rinowanzo sangana ne "mavanga machena". Isa mita yekupisa nehunyoro muworkshop kuti unyore shanduko mukupisa nehunyoro, uye uverenge mukana wekuonekwa kwemavara machena. Makambani ane mamiriro ezvinhu anogona kufunga nezvekuisa michina yekubvisa hunyoro. Kune zvivakwa zvecomposite zvine layer yakawanda zvine hunhu hwakanaka hwekudzivirira, zvakakosha kufunga nezvekumisa kugadzirwa kana kugadzira zvivakwa zvecomposite zvine layer imwe chete kana kuti zvinopindirana. Pamusoro pezvo, paunenge uchivimbisa kushanda kwakajairika kweglue, zvinokurudzirwa kuderedza huwandu hwemushonga unoshandiswa nemazvo, kazhinji ne5%.
1.6 Kunamira pamusoro
Kana pasina zviratidzo zvakajeka zvinowanikwa uye dambudziko re "mavara machena" risingagone kugadziriswa, maitiro ekuputira padivi realuminium coating anogona kufungwa nezvawo. Asi maitiro aya ane zvipingamupinyi zvakakura..Kunyanya kana VMCPP kana VMPET aruminiyamu yaiswa pakupisa nekumanikidzwa muovheni, inogona kusimba, uye maitiro ekubatanidza anofanira kugadziriswa. Pamusoro pezvo, simba reganda rearuminiyamu rinogona kudzikira.
1.7 Tsananguro yakakosha yemamiriro ezvinhu apo hapana zvinhu zvisina kunaka zvakawanikwa mushure mekumira, asi "mavara machena" akaonekwa mushure mekukura:
Dambudziko rerudzi urwu rinowanzoitika muzvikamu zve membrane zvine hunhu hwakanaka hwekudzivirira. Kune zvivakwa zvePET/VMCPP nePET/VMPET/PE, kana chimiro che membrane chakakora, kana pakushandisa mafirimu eKBOPP kana KPET, zviri nyore kugadzira "mavara machena" mushure mekukwegura.
Mafirimu ane mipendero yakakura yezvimwe zvivako anowanzosanganawo nedambudziko rimwe chete. Mienzaniso inosanganisira kushandisa foil gobvu realuminium kana mafirimu matete akadai seKNY.
Chikonzero chikuru chechiitiko ichi che "nzvimbo chena" ndechekuti kune kubuda kwegasi mukati me membrane ye composite. Gasi iri rinogona kunge riri kuwanda kwezvinonyungudutsa zvakasara kana kuwanda kwegasi re carbon dioxide rinogadzirwa nekuita pakati pechinhu chinoporesa nemhepo yemvura. Mushure mekunge gasi rawa, nekuda kwehunhu hwakanaka hwemuganho wefirimu ye composite, harigone kuburitswa, zvichikonzera kuoneka kwe "nzvimbo chena" (mabhuru) mu composite layer.
Mhinduro: Pakubatanidza glue inobva mukunyungudutsa, ma process parameter akadai sekupisa kweovheni, vhoriyamu yemhepo, uye kumanikidzwa kusina kunaka zvinofanirwa kugadziriswa zvakanaka kuti zvive nechokwadi chekuti hapana solvent yasara mu glue layer. Dzora hunyoro mu workshop uye sarudza system yekuvhara glue yakavharwa. Funga nezvekushandisa curaring agent isingaburitse mabubbles. Pamusoro pezvo, pakushandisa glue inobva mukunyungudutsa, zvakakosha kuyedza hunyoro huri mu solvent, nezvinodiwa zvehunyoro ≤ 0.03%.
Zviri pamusoro apa inyaya yekuonekwa kwe "mavara machena" mumafirimu akabatanidzwa, asi kune zvikonzero zvakasiyana-siyana zvinogona kukonzera matambudziko akadaro mukugadzirwa chaiko, uye zvakakosha kuita sarudzo nekuvandudza zvichienderana nemamiriro chaiwo ekugadzirwa.
