Iingxaki ezilishumi eziqhelekileyo zomgangatho wefilimu yokupakisha umatshini wokupakisha ngokuzenzekelayo

Ngophuhliso kunye nenkqubela phambili yezixhobo zokupakisha, ukusetyenziswa koomatshini bokupakisha ngokuzenzekelayo kuxhaphake ngakumbi, ngakumbi kwi-detergent, izimonyo, ukutya, amayeza kunye namanye amashishini.I-Henkel China isepha ngomnye wabavelisi bokuqala kwishishini ukusebenzisa oomatshini bokupakisha ngokuzenzekelayo.Yaqala phakathi kwiminyaka yee-1980 kwaye inembali engaphezulu kweminyaka engama-40.Ifumene inkqubo yokutshintsha kwefilimu yasekhaya yokupakisha iplastiki ukusuka ekuqaleni, ukusuka kuluhlu olulodwa lwemathiriyeli ukuya kwiintlobo ezahlukeneyo zezakhiwo zemathiriyeli.

I-Qingdao Advanmatch yokupakisha imiqulu yefilim elaminated, ifilim eqengqelekayo, i-rollstock(https://www.advanmatchpac.com/plastic-film-roll-product/) kwinkqubo yokuvelisa kunye nokusetyenziswa kwefilimu yokupakisha yeplastiki ngaphezulu kweminyaka engama-20, sihlala sithobela kumgaqo womgangatho kuqala, kwaye baphumelele igama elihle kubathengi.Ke ngoko, ndishwankathela iingxaki zomgangatho wembonakalo, iziphumo, iingcebiso zokuphucula kunye nemigangatho yokwamkelwa kwezinye iifilimu ezithengwe ngabathengi kwabanye ababoneleli.Ndiyathemba ukubonelela ngolwazi lwereferensi kubasebenzisi bokugqibela.

Uxinzelelo olungalinganiyo

Ngethuba lokuqhawula umqulu wefilimu, ngenxa yokungalingani kwamandla okutya kunye nokukhulula, emva kokuba ulawulo lungekho kakuhle, isiphene somgangatho wokuxinana okungalinganiyo kwefilimu iya kuvela.Ngokuqhelekileyo ibonisa ukuba umgca wangaphakathi wefilimu uqiniswe kakhulu kwaye umgca wangaphandle ukhululekile.Ukusetyenziswa komqulu wefilimu onjalo kuya kubangela ukusebenza okungazinzanga komatshini wokupakisha, njengobungakanani bokwenza isikhwama esingalinganiyo, ukutenxa kwefilimu, kunye nokuphambuka okugqithisileyo kokutywinwa komphetho, okukhokelela ekubeni iimveliso zokupakisha zingahlangabezani neemfuno zomgangatho.Ke ngoko, uninzi lweemveliso zefilim ezineziphene ziyabuyiswa.

Ukuze ugweme le ngxaki yomgangatho, kuyimfuneko ukuthatha amanyathelo afanelekileyo okulawula ukugcina ukulingana kwamandla omoya.Okwangoku, uninzi loomatshini bokuqhawula ifilimu banezixhobo zokulawula uxinezeleko, ezinokuqinisekisa umgangatho wokunqunyulwa kwefilimu.Nangona kunjalo, ngamanye amaxesha ngenxa yezizathu zokusebenza, izizathu zezixhobo, ulwahlulo olukhulu kubungakanani kunye nobunzima beekhoyili ezingenayo kunye nezothulwa kunye nezinye izinto, iziphene zomgangatho ezinjalo zenzeka ngamaxesha athile.Ke ngoko, ukusebenza ngokucokisekileyo kunye nokulungelelaniswa kwangexesha kwezixhobo kuyadingeka ukuze kuqinisekiswe umgangatho wefilim roll amanqaku kunye nokusika.

Ubuso obungalinganiyo

Ngokuqhelekileyo, ubuso bokuphela komqulu wefilimu bufuneka ukuba bube bushelelezi kwaye bungabikho ukungalingani.Ukuba ukungalingani kudlula i-2mm, kuya kugwetywa njengento engafanelekanga.Ubuso obungalinganiyo besiphelo bubangelwa ikakhulu zizinto ezininzi ezifana nokusebenza okungazinzanga kwezixhobo zokujiya kunye nokusika, ubukhulu befilimu obungalinganiyo, kunye namandla angalinganiyo okudibanisa ngaphakathi nangaphandle.Imiqulu yefilimu eneziphene ezisemgangathweni ziya kubangela ukusebenza okungazinzanga komatshini wokupakisha, ukutenxa ifilimu, ukutenxa ngokugqithisileyo kokutywinwa komphetho kunye nezinye izinto ezingenakuhlangabezana neemfuno zomgangatho weemveliso zokupakisha ezifanelekileyo.Ngoko ke, iimveliso ezinjalo ezinomgangatho onjalo zihlala zikhatywa.

Umphezulu wamaza

Into ebizwa ngokuba yi-wavy surface yindawo engalinganiyo, egobileyo kunye ne-wavy ye-membrane roll.Esi siphene somgangatho asiyi kubangela kuphela iingxaki ezikhankanywe ngasentla ekusebenziseni umqulu wefilimu, kodwa kwakhona kuchaphazela ngokuthe ngqo ukusebenza kwezinto zokupakisha kunye nomgangatho wokubonakala kweemveliso zokupakisha, ezifana nokusebenza okuphantsi koxinzelelo kunye namandla okutywinwa. izinto eziphathekayo, kunye nokuguqulwa kweepateni eziprintiweyo kunye neengxowa ezenziwe.Ukuba i-defect esemgangathweni ibonakala kakhulu kwaye inzulu, i-coil enjalo ayikwazi ukusetyenziswa kumatshini wokupakisha ngokuzenzekelayo.

Ukutenxa ngokugqithisileyo kokunqunyulwa

Ngokuqhelekileyo, ukuphambuka kwe-slitting yomqulu wefilimu kuyadingeka ukuba kube ngaphakathi kwe-2-3 mm.Ubuninzi kakhulu buya kuchaphazela umphumo opheleleyo wesikhwama sokubumba, njenge-offset, incompleteness, i-asymmetry yesikhwama sokubumba kunye nezinye iziphene zomgangatho wemveliso yokupakisha.

Umgangatho odibeneyo

Umgangatho odibeneyo ngokuqhelekileyo ubhekisela kwiimfuno zenani, umgangatho kunye nokumakishwa kwamalungu.Inani leengqungquthela zefilimu eziqhelekileyo zifunekayo ukuba zibe ngaphantsi kwe-1 kwi-90% ye-rolls, kwaye ngaphezu kwe-2 kwi-10% ye-rolls;Inani lamalungu ane-diameter ye-film roll engaphezulu kwe-900mm kufuneka ibe ngaphantsi kwe-3 kwi-90% ye-rolls, kunye ne-4 ukuya kwi-5 kwi-10% ye-rolls.

Umdibaniso wefilimu awuyi kutyholwa ngokugqith' emgceni.Isiphambuka siya kuba sembindini weepateni ezimbini.Ukudibanisa kuya kuba okupheleleyo, okugudileyo kunye nokuqina.Iteyiphu yokuncamathela ayiyi kuba ngqindilili kakhulu.Ngaphandle koko, ifilimu iya kuxutywa kwaye iphulwe, kubangele ukuvala, okuchaphazela ukusebenza okuqhelekileyo komatshini wokupakisha, ukwandisa umthwalo wokusebenza kunye nokunciphisa ukusebenza kakuhle kwemveliso.Amalungu aya kuphawulwa ngokucacileyo ukuququzelela ukuhlolwa, ukusebenza kunye nonyango.

Ingxaki yomgangatho ongundoqo

I-roll cores esetyenziswa ngokuqhelekileyo zizinto zephepha ezinobubanzi obuyi-76mm ngaphakathi.I-defect ephambili yekhwalithi yi-deformation ye-roll core, ebangela ukuba ifilimu yefilimu ingakwazi ukufakwa ngokuqhelekileyo kwi-clamp yefilimu yomatshini wokupakisha, ngoko ayikwazi ukusetyenziswa kwimveliso.

Izizathu eziphambili ze-deformation ye-roll core ye-movie roll ngumonakalo wokugcinwa kunye nokuthutha amakhonkco, ukutyunyuzwa kwe-roll core ngoxinzelelo olugqithiseleyo lwefilimu, umgangatho ombi kunye namandla aphantsi e-roll core.

Indlela yokujongana nesi siphene somgangatho ikholisa ukuyibuyisela kumboneleli ukuze ibuyiselwe umva kunye notshintsho olungundoqo.

Roll indlela

Uninzi koomatshini bokupakisha ngokuzenzekelayo banemfuno ezithile kwicala lefilimu ephumayo.Le mfuneko inqunywe ngokukodwa ngokwesakhiwo somatshini wokupakisha kunye noyilo lwepateni yokuhlobisa yeemveliso zokupakisha.Ngokuqhelekileyo ezantsi okanye phezulu kuqala ngaphandle.Ngokuqhelekileyo, le mfuneko ichazwe kwiinkcukacha okanye imigangatho yomgangatho wezinto zokupakisha zemveliso nganye.Iziphene zomgangatho ezinjalo zinqabile phantsi kweemeko eziqhelekileyo.

Ubungakanani bokwenza ingxowa

Ngokuqhelekileyo, ubude bomqulu wefilimu yiyunithi yokulinganisa.Ubude ubukhulu becala bugqitywe ngobuninzi bangaphandle kunye nomthamo womthwalo wefilimu umqulu osebenzayo kumatshini wokupakisha, kwaye udla ngokusetyenziswa kwiimitha / umqulu.

Isiphoso somgangatho wenani elinganeleyo leengxowa zefilimu zefilimu nazo aziqhelekanga, kodwa bobabini umthengisi kunye nomthengi banenkxalabo malunga nayo.Uninzi lwabavelisi banovavanyo kwisalathiso sokusetyenziswa kwekhoyili yefilimu.Ukongezelela, akukho ndlela efanelekileyo yokulinganisa ngokuchanekileyo kunye nokuhlolwa kwekhoyili yefilimu ngexesha lokunikezelwa kunye nokwamkelwa.Ke ngoko, kukho iimbono ezahlukeneyo okanye iingxabano malunga nesi siphene somgangatho, ezidla ngokusonjululwa ngothethathethwano.

Umonakalo wemveliso

Umonakalo wemveliso ubukhulu becala ubakho ngexesha lenkqubo ukusuka ekugqityweni kokunqunyulwa kwemveliso ukuya kunikezelo lwemveliso.Kukho ubukhulu becala umonakalo wefilim (njengomkrwelo, ukukrazuka, umngxuma…), ungcoliseko lwefilim, ukonakala kwephakheji yangaphandle (umonakalo, amanzi, ungcoliseko…), njl.

Ukuze ugweme iziphene zomgangatho onjalo, kuyimfuneko ukuqinisa ulawulo lweekhonkco ezifanelekileyo, ukwamkela ukusebenza okusemgangathweni kunye namanyathelo okukhusela asebenzayo.

Ukuchongwa kwemveliso

Uluhlu lwefilimu luya kuba namanqaku acacileyo kunye apheleleyo emveliso, kwaye iziqulatho eziphambili ziya kubandakanya: igama lemveliso, ukucaciswa, ubungakanani bokupakisha, inombolo ye-odolo, umhla wokuvelisa, umgangatho kunye nolwazi lomthengisi.

Injongo ephambili yolu lwazi kukuhlangabezana neemfuno zokuhlolwa kokuhanjiswa kunye nokwamkelwa, ukugcinwa kunye nokuhanjiswa, ukuveliswa kunye nokusetyenziswa, ukulandelela umgangatho, njl.

Iziphene zomgangatho wembonakalo yefilim zivela ikakhulu kwinkqubo elandelayo yokuveliswa kwefilimu kunye nenkqubo yokugcinwa kunye nokuthutha.Ngoko ke, ukulawulwa komgangatho weli khonkco kunokuphucula kakhulu izinga lokufaneleka kwemveliso yegalelo-imveliso, kwaye uzuze kabini umphumo ngesiqingatha somzamo wokuphucula umgangatho wemveliso kunye nokuphucula izibonelelo zoqoqosho zeshishini.
