Ubuchwepheshe bokubeka uphawu kanye nemishini

Ukubeka uphawu kubhekisela ezinqubweni ezihlukahlukene zokuvala ezenziwa ngemva kokupakishwa amabhokisi okupakisha ama-wholesale baklava umkhiqizo onezinto zokupakisha noma iziqukathi zokupakisha ukuqinisekisa ukuthi okuqukethwe kuhlala kuphakethe futhi kugweme ukungcoliswa ngesikhathi sokujikeleza, ukuthuthwa, ukugcinwa nokuthengisa. Inencazelo ebanzi futhi ibizwa nangokuthi ukubeka uphawu, ukubekwa uphawu, noma ukubekwa uphawu. Ngemva kokuqeda ukupakishwa kwezintoamabhokisi okupakisha ama-wholesale baklavaesitsheni, umshini ovala isitsha ubizwa ngokuthi imishini yokuvala. Iziqukathi ezihlukene zokupakisha zinezindlela ezihlukene zokuvala, futhi izinhlobo zezinhlobo zokuvala nemishini yokuvala ziyahlukahluka. Kunezinhlobo eziningi zezindlela zokuvala, izinto zokwakha kanye nezingxenye ezisetshenziswa enqubweni yokuvala nokupakisha. ezihlukaniswe zibe izinhlobo ezilandelayo ngokusho kokuba khona noma ukungabi khona kwezinto zokuvala kanye nezindlela ezahlukene zokuvala.

(1)Azikho izinto zokuvala , kukhona ukuvala ngokucindezelwa okushisayo, ukutywinwa kwe-welding, ukuvala okunamathiselwe, ukuvala ukugoqa kanye nokuvala i-plug-in.

(2)Kukhona izinto zokuvala , okuhlanganisa ukugoqa, ukuvala uphawu, ukuvala uphawu ngokucindezela kanye nokusonta uphawu.

(3)Kukhona izinto ezisizayo zokuvala . Lolu hlobo lokuvala luhlanganisa ukuvala i-ligation nokuvala nge-tape.

Ekuphileni kwansuku zonke, le mikhiqizo yokuvala ingabonakala yonke indawo, njengamabhodlela engilazi kabhiya, i-soda nezinye iziphuzo ze-carbonated. Ikakhulukazi yimikhiqizo yokuvala ingcindezi, evame ukubizwa ngemishini yokufaka ama-capping. Amanzi asemabhodleleni kanye nemikhiqizo yemithi kuvame ukuvalwa nge-screw capping, futhi ngokuvamile ibizwa nge-capping machines. Ukudla okusemathinini ezitsheni ze-tinplate kuvalwa ngokucwiliswa nokuvala, okujwayele ukubizwa ngokuthi umshini wokuvala ithini. Ngeke ngizibale ngamunye ngamunye. Wonke angaphansi kwesigaba semishini yokupakisha.

 

1. Imisebenzi kanye nezinhlobo zokunamathela

Indlela yokuvala imikhiqizo yokupakisha usebenzisa izinto zokunamathisela ibizwa ngokuthi inqubo yokunamathela. Izinzuzo zayo inqubo elula, ukukhiqiza okuphezulu, amandla okubopha okuphezulu, ukusatshalaliswa kokucindezeleka okufanayo, ukubekwa uphawu okuhle, ukuguquguquka okubanzi, kanye nokwenyuka kokufakwa kwe-thermal kanye nezakhiwo zokufakelwa. Isetshenziswa kabanzi embonini yokupakisha ukuhlanganisa izinto ezahlukahlukene njengephepha, indwangu, izinkuni, ipulasitiki nensimbi. Idlala indima ebalulekile ezinqubweni zokuvalwa, ukukhiqizwa kwempahla eyinhlanganisela, ukuvalwa kwamabhokisi, ukuhlubula, kanye nokulebula.

Kunezinhlobo eziningi zokunamathisela ezinezithako eziyinkimbinkimbi, futhi izinto eziningi zemvelo nezokwenziwa zingasetshenziswa njengezinamatheliso. Ngokwemvelo yezinto eziyisisekelo ze-adhesive, ingahlukaniswa ngama-adhesives we-inorganic kanye nama-organic adhesive; ngokusho kwefomu elibonakalayo le-adhesive, lingahlukaniswa ngezigaba ezintathu: uhlobo oluncibilikayo emanzini, uhlobo lwe-solvent kanye nohlobo lwe-hot-melt; ngokuya ngokuthi i-adhesive iyashiswa yini uma isebenza, ihlukaniswe ibe yi-glue ebandayo kanye ne-adhesive encibilikayo eshisayo.

2. I-cold glue bonding ayidingi ukushisa futhi yenziwa ekamelweni lokushisa.

Kukhona izinto ezinamathelayo ezincibilika emanzini kanye nezinamatheliso ezisekelwe ku-solvent. Izinamatheliso ezisekelwe ku-solvent zifaneleka kuphela ku-120-degree melt bonding engasebenzisi imishini yokuhlanganisa i-waterline ngenxa yemikhawulo yezinhlobo zezilwane, ukuphepha, imithetho yokuvikela imvelo, nokuphepha kokukhiqiza. Endabeni yokunamathela, izinamathiselo ezincibilika emanzini zisetshenziswa ikakhulukazi ekukhiqizeni. Uhlobo lwe-Dongji i-Xinheli lusetshenziswe isikhathi eside kakhulu emaphaketheni futhi lunomthamo omkhulu kakhulu. Izinzuzo zayo ukusebenza okulula, izindleko eziphansi zokuphepha namandla aphezulu okubopha. Ingahlukaniswa ngezigaba ezimbili: izinto ezinamathelayo zemvelo ezincibilika emanzini kanye nezinamatheliso ezincibilika emanzini zokwenziwa. Kuwukunamathela okungokwemvelo okusekelwe emanzini okonga amandla aphansi namandla aphezulu. Isexwayiso sohlobo lwe-Fu. Inhloso enkulu ukuvala amabhokisi nephepha. Yenziwe ngamashubhu ephepha empuphu engashintshi kanye nezikhwama zephepha. Yenziwe ngofulawa oluhlaza noma imifino. Enqubweni yokukhiqiza amakhadibhodi e-Wabo, gwema ukusebenzisa isitashi. Okunamathelayo. Izinzuzo zayo ukuthi kulula ukwakha nokunamathela emathinini ensimbi, ingakwazi ukubopha iphepha kahle, futhi inokumelana nokushisa okuhle. Okubi ukuthi ukuchezuka kokunamathela kuncane kakhulu.

Ukunamathela okungalungile kumapulasitiki kanye nama-coatings, ukumelana namanzi okumpofu. Impahla ehlanganisiwe yezinto ezibonakalayo kanye nongqimba lokubulala, njengeglue yezilwane, ingasetshenziswa njengengxenye eyinhloko yenhlanganisela yokumanzisa kabusha yetheyiphu yokuvala, nanjengokunamathela kwetheyiphu yokuvala: njengeglue eyomile, isetshenziswa kakhulu. njengesitika samabhodlela kabhiya. Ilebula yokunamathisela, ngoba ingahlangabezana nokumelana nokucwiliswa kwamanzi abandayo okudingekayo ezikhwameni zamalebula ebhodlela likabhiya, futhi ingawashwa ngamanzi ane-alkali ngemva kokuba ibhodlela seligaywe kabusha. Ingase futhi isetshenziselwe ukwenza isakhi samakhemikhali esisetshenziselwa i-Daizhi foil kanye nokuhlanganiswa kwemvelo, njenge-emulsion yenjoloba yemvelo, okuyi-emulsion emhlophe ekhishwe ezihlahleni zenjoloba, isetshenziswa kakhulu ekufakweni njengengxenye eyinhloko ye-adhesive ye-polyethylene nephepha. izinhlanganisela ezakhiweni zezikhwama zezendlalelo eziningi. Iyakwazi ukuzivala ngokucindezelwa, ngakho ijwayele ukusetshenziselwa amaswidi azivala wona. I-Adhesive yokugoqa, amabhokisi okuvalwa kwengcindezi kanye nezikhwama zephepha zokuvala ingcindezi.

Izinamatheliso ezincibilika emanzini zokwenziwa.

Iningi lalawa ma-adhesive ama-resin emulsions, ikakhulukazi i-polyvinyl acetate emulsion-stable ukumiswa kwezinhlayiya ze-vinyl acid emanzini. Lolu hlobo lwe-adhesive lusetshenziswa kabanzi kuamabhokisi okupakisha ama-wholesale baklava, njengokwenza, ukuvala noma ukulebula amabhokisi, amabhokisi, amashubhu, izikhwama namabhodlela. Ngenxa yochungechunge lwezakhiwo ezinhle kakhulu, liye lashintsha kakhulu izinto zokunamathela zemvelo.

Cold glue bonding inqubo

Inqubo yokubopha i-adhesive glue ebandayo ingasebenza ngesandla noma ngemishini yokumboza. Izinqubo zokusebenza eziyinhloko zokubopha yilezi: ukumboza, ukucindezela nokuphulukisa (i-volatilization). Ukwelapha kuyinqubo lapho amanzi noma i-organic solvent encibilikisa ingcina ebandayo ihwamuka kuze kube ingcina ngokwayo iqina. Ngemuva kokuthi i-adhesive isetshenziswe ku-adherend, idinga ukuhlala esimweni esiboshiwe isikhathi eside kuze kube yilapho iqina. Sebenzisa ibhulashi noma isibhamu sokufutha uma ugcoba ngesandla. Lapho uhlanganisa okokusebenza kwemishini, cishe kunezindlela ezintathu zokusebenza: Indlela yokuhlanganisa i-D roller. i-glue ebandayo esitsheni isakazwa ngama-roller ajikelezayo. Kunezindlela ezimbili zokulungisa ukushuba kweglue: lapho i-roller i-cylindrical ebushelelezi, ingalungiswa ngegebe phakathi kwendawo yesondo kanye ne-scraper; lapho i-roller surface inemifantu, kuncike ekujuleni kwe-groove. Indlela yokugqoka i-roller ingasebenzisa ama-adhesive ekamelweni lokushisa. Isakhiwo semishini silula futhi sisetshenziswa kakhulu emishinini yokunamathisela amabhokisi. Ngenxa yokuthi ingakwazi ukufaka i-glue ngokugcwele emiphethweni yebhokisi, ibhokisi lingavalwa ngokuphelele ngisho noma okuqukethwe kufomu lempushana. Kodwa-ke, imishini idinga ukuhlanzwa nsuku zonke, futhi ukulahlekelwa kwe-adhesive kukhulu; uma kusetshenziswa izixazululo zemvelo, izindaba zokuvikela imvelo zidinga ukucatshangelwa.

3. Indlela yokugcoba umlomo wombhobho. Kunezindlela ezimbili zokufafaza i-glue nge-nozzle.

Indlela yokuhlinzeka nge-adhesive ku-nozzle ingaba ithangi lokucindezela noma iphampu yokucindezela. Uma ufutha i-glue ngendlela engathinteki, kunebanga elithile phakathi kwe-nozzle kanye nento okufanele ilandelwe, futhi ipompo yokucindezela ene-spray pressure ephakeme isetshenziswa kakhulu. Ngaphezu kwalokho, ngokombono wesondlo, ngoba

Ukuze izinto ezifana amakhadibhodi lukathayela lapho iphephaamabhokisi okupakisha ama-wholesale baklavaizinsalela zivame ukunqwabelana ku-nozzle, indlela yokungathintani ifaneleka kakhulu. Uma kuqhathaniswa nendlela yokugqoka i-roller, isiqondiso sokungathinteki singalungiswa ngokuzenzakalelayo, futhi imishini ayidingi ukuhlanzwa nsuku zonke; kodwa-ke, njengoba iglue ifafazwa nge-nozzle enobubanzi obuncane, kunenkinga yokuthi iglue iyoma futhi ivimbe umlomo. Ngenxa yalesi sizathu, ezinye izinyathelo zidinga ukuthathwa Izinyathelo zihlanganisa ukubeka umlomo wombhobho endaweni eswakeme noma ukuphefumula umswakama ngasekugcineni kombhobho lapho umugqa wokuhlanganisa umiswa. Ngaphezu kwalokho, ezinye izinto zokunamathisela zizosheshisa ukugqwala kwama-nozzles ensimbi, okufanele kucatshangelwe lapho kukhethwa.

indlela yokugcoba inkungu ye-Acid. Awukho umehluko omkhulu ekubunjweni kwe-spray gluing ne-nozzle gluing systems. Umehluko wukuthi i-gluing eyomile yenza i-glue ebandayo isakaze ngendlela eqondile, kuyilapho i-spray gluing yenza i-glue ebandayo isakaze ngesimo senkungu, Isizathu siwukuthi ukugqoka kudinga indawo enkulu. Umphumela omuhle wokubopha ungatholakala ngokusebenzisa inani elincane leglue, futhi isikhathi se-lamination singafinyezwa. Ububi ukuthi umugqa wokuqala ulufifi. Isetshenziswa kakhulu ukuvala amabhokisi kathayela 3. Ingcina ye-adhesive encibilikayo eshisayo

Kunezindlela ezintathu zokulungisa ingcindezi ngaphakathi kokusebenza kwempahla yendwangu noma igumbi le-solvent ye-organic lapho imishini ye-roller ivaliwe.

I-Hot melt adhesive iyingcina eqinile esekelwe kuma-polymers we-thermoplastic. Inqubo yayo yokuhlanganisa yile: ukunamathela okuncibilika, ukunamathela, ukucindezela nokuqinisa (ukupholisa). I-glue enamathelayo iyashisisa futhi incibilike ingcina, futhi ukuqina kuyinqubo yokupholisa ingcina encibilikisiwe. ehlukile emakhazeni

I-glue liquid iyahwamuka. Ngenxa yokuthi isikhathi sokupholisa sifushane kakhulu kunesikhathi sokuhwamuka, singajwayela isivinini sokukhiqiza esiphezulu semigqa yokukhiqiza yokupakisha okuzenzakalelayo. Kuyi-adhesive ebaluleke kakhulu ekufakweni kwamanje. Kunezinamathiselo ezincibilikayo ezintathu ezivame ukusetshenziswa kakhulu. Eyokuqala i-ethylene-vinyl acetate copolymer (EVA), engahlanganiswa ne-wax kanye ne-tackifying resin ukwenza ingcina ewusizo kakhulu. Umsebenzi we-wax ukunciphisa i-viscosity nokulawula Ijubane lokuphulukisa, ukuguquguquka nokumelana nokushisa kwe-adhesive, indima ye-resin tackifying ukulawula i-viscosity nokunamathela. Uhlobo lwesibili luyi-adhesive encibilikayo eshisayo esekelwe ku-polyethylene enesisindo esiphansi samangqamuzana, esetshenziselwa kakhulu ukuhlanganiswa kwephepha, njengokuvalwa kwebhokisi kanye nokuvala isikhwama. Uhlobo lwesithathu lwe-adhesive olusekelwe ku-amorphous polypropylene lusetshenziselwa ukugcwalisa iphepha ukuze kukhiqizwe izinto zokupakisha ezikwazi ukumelana namanzi noma ukupakishwa kwezinto zokuhamba eziqinisiwe ezinezendlalelo ezimbili.

Ngaphezu kwalokho, kunezinamathiselo ezincibilikayo ezishisayo ezihlangabezana nezinye izinjongo ezikhethekile. Kungakhathaliseki ukuthi hlobo luni lwe-adhesive encibilikayo eshisayo, bonke banenzuzo eyodwa eyisisekelo efanayo, okungukuthi, bangahlanganiswa ngokupholisa nje. Kodwa-ke, ngenxa yokuthi zelapha ngokushesha, ukunamathela okubi ngokuvamile kwenzeka lapho ukuncibilika okushisayo kuqinisa ngaphandle kokuthinta i-substrate emanzi, futhi amandla abo ayancipha ngokushesha lapho izinga lokushisa likhuphuka. Uma zenziwe kahle, zingalungela iningiamabhokisi okupakisha ama-wholesale baklavaizicelo. , kodwa ayifaneleki imisebenzi yokugcwalisa eshisa kakhulu noma ukupakishwa kokubhaka.

I-D roller gluing indlela. Indlela ilula, kodwa umphumela jikelele awulungile.

Indlela yokufaka i-nozzle.

I-glue encibilikisiwe eshisayo ifakwe ku-tube yokugcina i-glue 6, futhi ithubhu yokugcina i-glue ixhunywe ku-nozzle yokugqoka i-7; ibhokisi likathayela 10 lithunyelwa endaweni yokunamathisela ingcina ngebhande lokuthutha elingu-9, futhi umlomo wombhobho ufutha ingcina ecindezelweyo ukuze yakhe ingcina esiqeshini sekhathoni. Isendlalelo seglue 8 siyagoqwa, sicindezelwe futhi sipholile ukuze kuqedelwe ukubopha. Njengoba i-nozzle ingahlangani nebhokisi futhi i-glue ifafazwa ngaphansi kwengcindezi, ijubane lokumboza liyashesha futhi lilingana. Phakathi kwezindlela ezihlukahlukene zokuhlanganisa, yiyona esetshenziswa kakhulu.

Indlela yokufaka i-flat glue.

I-glue encibilikisiwe eshisayo igcinwe ku-tank yokugcina i-glue 11. Indawo ehlanganiswe ngeglue yesiqephu sebhokisi lekhadibhodi 13 iphansi futhi ibekwe phezu kwepuleti eliyisicaba elihlanganiswe neglue 12. Ipuleti eliyisicaba elihlanganiswe neglue liya phezulu naphansi, lithwele. ibhokisi elingenalutho ethangini lokugcina lapho lehla. Iglue isetshenziswa ethangini leglue, bese phezulu ngokugoqa, ukucindezela nokupholisa ukuze kuqedelwe ukubopha. I-glue-coating flat plate iqoshwe ngezikhala ezingenalutho ezifanele izingxenye ze-glue-coating zebhokisi elingenalutho, ukuze indawo ngayinye ehlanganiswe ne-glue ifakwe ngesikhathi esisodwa, ngaleyo ndlela ithuthukise ukusebenza kahle. Le ndlela isetshenziswa kakhulu ekunamathiseleni amabhokisi.
