Isingeniso
Ukubhala ephepheni bekuyindlela ethandwayo yokuxhumana emakhulwini eminyaka. Kuze kube yilapho kusungulwa i-inthanethi, lapho ama-imeyili ethulwa, izincwadi nokuxhumana okusemthethweni kwakuvame ukubhalwa ephepheni. Kodwa naphezu kwalokhu kushintshela ezincwadini zedijithali, siseningi indawo yamabhizinisi angena embonini yokwenza amaphepha ukuze enze inzuzo. Unalokhu engqondweni, lesi sihloko sizobheka amathiphu abalulekile okukhetha imishini yokwenza amaphepha, ukuze amabhizinisi akwazi ukuthola amamodeli angcono kakhulu ngokuzethemba!

Ukukhetha umshini wokwenza iphepha
Izinto okufanele zicatshangelwe lapho ukhetha umshini wokwenza iphepha
Isipiliyoni kanye nedumela lomkhiqizi
Ulwazi lomkhiqizi lubalulekile emabhizinisini ngoba lungabonisa ukuthi imikhiqizo yomkhiqizi ingeyekhwalithi enhle. Abakhiqizi abakha imishini yokwenza amaphepha isikhathi eside bazobe sebefundile ukuthi imboni idingani, futhi bazokwakha imishini ehlangabezana nalezi zidingo. Abanye abakhiqizi abahloniphekile amabhizinisi angakhetha kubo bahlanganisa i-Technocarton, i-Burgo Benelux, ne-Toscotec SPA.
Cost
Izindleko zomshini zizohluka kuye ngobuchwepheshe obusetshenzisiwe, ukuphuma komshini, nosayizi wawo. Imishini yamaphepha ibiza kusukela ephansi I-US $ 9000 kuya I-US $ 97000. Ngakho-ke, amabhizinisi kufanele akhethe imishini angakwazi ukuyikhokhela, engakwazi ukwanelisa izidingo zawo.
Ukusebenza kalula nokugcinwa
Eminye imishini yokwenza iphepha ingase ibe lula ukuyisebenzisa, kanti eminye ingase ingabi lula ukuyisebenzisa. Lapho uthenga umshini wokwenza iphepha, amabhizinisi kufanele aqale athole ukuthi kulula yini ukuwusebenzisa. Ukuthola uchwepheshe kumenzi kungaba usizo nakubo. Ngaphezu kwalokho, amabhizinisi kufanele abuze ukuthi umshini kufanele ulungiswe kanjani kanye nokuba khona kwezingxenye ezisele. Ibhizinisi lingaphinda licele ukuqeqeshwa kwabasebenzi.
Ukuphepha
Amabhizinisi kufanele athenge imishini enezici ezinhle zokuphepha ukuze aqinisekise ukuphepha kwabasebenzisi. Imishini kufanele isetshenziselwe emakamelweni anendawo eyanele ukuze kugwenywe ukunqunywa ama-nips nama-pinch points. Inqubo efanele kufanele ngaso sonke isikhathi isetshenziswe uma uqhuba umshini. Abasebenzi kufanele futhi bagqoke kahle izinto zokuzivikela ezifana nezingubo zamehlo, ama-ear muff, i-overall/coat, namabhuzu okuphepha.
Ukukhiqiza
Amandla okukhiqiza inani lephepha elikhiqizwa iyunithi yesikhathi. Ikalwa ngamamitha ngomzuzu, futhi iyahlukahluka ngomshini ngomshini. Eminye imishini inamandla okukhiqiza 200m / iminithi, kuyilapho abanye benamandla 300m / iminithi. Amabhizinisi kufanele akhethe imishini enomkhiqizo ohambisana nezidingo zawo zokukhiqiza.
Usayizi wephepha
Imishini yokwenza amaphepha inobukhulu obuhlukene bephepha ekhiqizwayo. Ububanzi bephepha buncike ekusetshenzisweni kwebhizinisi. Ububanzi bephepha obutholakalayo buhlanganisa u-1600mm, 1800mm, no-2640mm. Amabhizinisi kufanele akhethe ububanzi bephepha obufanele kuye ngezidingo zamaklayenti awo.
Izici zomshini wokwenza iphepha
I-headbox
I-headstock ithola ingxube ye-pulp futhi iyibambe ngaphambi kokuthi ithathwe ngokuhlunga. Izinto ezintathu zenziwa ku-headbox: ukuhlephula amabhlogo we-pulp ngokunyakaza, ukuqinisekisa ukusatshalaliswa kokugeleza ngomshini wephepha, nokulawula isivinini sendiza eshiya ibhokisi lekhanda ngokucindezela ebhokisini lekhanda. Lokhu kuvumela i-pulp ukuthi igeleze emigqeni eminingi ezungezayo enezimbobo. I-pulp, ebizwa nangokuthi isitoko, ishiya ibhokisi lekhanda njengejethi yamahhala esikrinini esakha lapho inqubo yokuhlunga iqala.
Isigaba sokwakha
I-pulp idlula etafuleni le-fourdrinier, uchungechunge lwamabhokisi e-vacuum, kanye ne-sofa roll. Etafuleni le-fourdrinier, i-pulp ikhishwa ngamanzi ngokufakwa ocingweni olwenziwayo olunama-foil ngaphansi kwalo. Amabhokisi e-vacuum asiza ukucaba indawo engaphezulu ye-pulp (manje eyishidi) futhi athuthukise ukuphela kwayo. Ngenkathi ku-roll roll, amanzi amaningi akhishwa eshidini.
Isomisi
Iphepha lishiya ingxenye yokunyathelisa bese lingena ekomeni ngokuvumelana kwe 40-45%. Umshini wokomisa unawo 40 ukuze 70 amasilinda okomisa umusi asusa amanzi amaningi ngokuhwamuka. Imishini yokomisa isetshenziselwa ukubamba izindawo ezishisayo.
I-Calendering
Kukhalenda, iphepha lidluliswa esitakini sekhalenda. Isitaki sekhalenda siyisitaki sensimbi esiqinile. Amaroli ensimbi adlulisela imijikelezo yokucindezela ephezulu ephepheni. Isitaki sekhalenda sinciphisa ukujiya kwephepha. Kwenza futhi iphepha liphrinteke ngokwengeziwe ngokwandisa ubushelelezi bephepha.
Isigaba sabezindaba
Esigabeni sabezindaba, amanzi akhanywa kuwebhu emanzi. Lokhu kwandisa okuqukethwe okuqinile futhi kunciphisa ukushuba kwephepha. Kuyasiza futhi ukuthuthukisa ukuhlangana kwemicu.
Reel
Iwebhu yephepha ilinyazwe kumqulu omkhulu owaziwa ngokuthi i-reel ukulungiselela ukugcinwa. I-Calender kanye ne-reel kuphakathi kwezigaba zokugcina zokwenza iphepha.
I-Winder
Kusuka ku-winder, iphepha liyakhishwa futhi lisikwe ngosayizi abahlukene ngokuya ngemininingwane yeklayenti.

Imicabango yokugcina
Ukuthola umshini ofanelekayo wokwenza iphepha webhizinisi kungasho umehluko phakathi kokwenza inzuzo noma ukulahlekelwa. Kodwa-ke, ngale kwalokhu inzuzo yokuthuthukisa amabhizinisi ngokwezidingo zamakhasimende kanye nokugcina ikhwalithi yephepha elikhiqizwayo. Lesi sihloko sibheke izinto ezibalulekile okufanele zicatshangelwe lapho uthenga imishini yokwenza iphepha. Vakashela Cooig.com ngokukhethwa kwemishini engcono kakhulu yokwenza iphepha emakethe.
