Iyini inqubo ye-Glassine Supercalendering?
Kwadalwa ngo 11.20
High-Level Summary
Inqubo ye-Glassine Supercalendering iyindlela ethile yokwelapha emishini esetshenziselwa ukukhiqiza iphepha le-glassine—iphepha elithambile, elikhanyayo, eliqinile, nelicacile. Le nqubo ihilela ukudlula uhlobo oluthile lwephepha emshinini we-supercalender, umshini omkhulu ophakamisa inhlanganisela yokucindezela okukhulu, ukungqubuzana, nokushisa. Lokhu kushintsha ngokomzimba isakhiwo sephepha, kukhinyiselwa futhi kupholishwa ubuso bayo ukuze kufezwe izici zayo ezihlukile.
Ukuhlukanisa Inqubo Isinyathelo Ngesinyathelo
Ukuze siqonde kahle, ake sibheke uhambo lonke lwephepha.
1. Iphepha Elisisekelo: Impahla Erawula
Inqubo ayiqali ngephepha nje. Iqala ngephepha elikhethekile elikhiqiziwe elinokwakheka okubili okubalulekile:
- Highly Refined Pulp: I-pulp ye-wood ibhujiswa futhi ihlanzwa isikhathi eside kakhulu. Lokhu kunciphisa kakhulu ubude bezintambo zephepha futhi kukhuphule indawo yazo, kuvumela ukuthi zixhume ndawonye ngokuqinile kakhulu.
- Ayikho Imfucumfucu: Ngokwehlukile kumaphepha aphezulu okushicilela aqukethe imfucumfucu ye-clay noma ye-calcium carbonate ukuze kudaleke ubukhazikhazi, iphepha le-glassine eliyisisekelo ngokuvamile linezinga elincane noma alikho imfucumfucu. Ubukhazikhazi bayo buvela ngokuphelele emsebenzini wezobuchwepheshe.
2. I-Supercalender: Inhliziyo ye-Process
I-supercalender ayisona isikhumbuzo esilula. Iyi-stack yezirolli ezihlukahlukene:
- Hard Rolls: Wenziwe ngesinyithi esibandayo, esigcwele kahle futhi sikhanyisiwe.
- Soft Rolls: Zenziwe ngendwangu ethambile, iphepha, noma izinto ezihlanganisiwe. Lezi zinciphisa kancane.
Lezi ziqwenga ziqinile phezulu, futhi iphepha lidlula phakathi kwe-"nip" (iphuzu lokuxhumana) phakathi kwephela lezi ziqwenga.
3. Umsebenzi "Supercalendering"
Njengoba iphepha lihamba ngesivinini esiphezulu phakathi kwezikhala ze-supercalender, izinto eziningi zenzeka ngasikhathi sinye:
- Extreme Pressure: Ubukhulu obukhulu be-roll stack buveza ingcindezi enkulu ephepheni (emkhakheni wezinkulungwane zePlenty of pounds ngalinye le-inchi elihambayo).
- Umswakama kanye Nezinga Lokushisa: Umehluko wesivinini sesikhala phakathi kwamagagasi ensimbi aqinile kanye namagagasi athambile, angashintshashintshi udala isenzo esinamandla sokuhlakulela nokupholisha. Lo mswakama udala ukushisa okukhulu.
- Ukucindezela nokuphola: Ukuhlanganiswa kweMithwalo, Ukucindezela, kanye Nokushisa kunezinguquko ezithile:
- Ithambisa futhi icindezela noma yiziphi izintaba ezincane nezindawo ezisele ebusweni bephepha.
- Ithinta isakhiwo sangaphakathi sephepha, icindezela amaphakethe omoya futhi iphonsa amafayibha endaweni eqinile, ethile kakhulu.
- Ithambisa ubuso bayo ukuze kube nesikhanyiso esiphezulu, njengokukhanya kwesibuko.
Umphumela: Izici Eziyinhloko Zephepha le-Glassine
Le nqubo eqinile inika iphepha le-glassine izici zayo ezichazayo:
1. Ubukhulu Obuphezulu & Ukucaca: Uhlaka olucindezelwe, olungenawo umoya lwenza iphepha libe nokuqina. Lokhu kwehlisa ikhono lalo lokusabalalisa ukukhanya, okuyinto edala ukubukeka okungathi "kucacile" noma "kwe-glassy".
2. Umphezulu Ohlanzekile Nojolile: Umsebenzi wokupholisha udala umphezulu ohlanzekile, ojolile ophakeme ongenamikhono yokuphuma.
3. Ukumelana Nezikhukhula Nezinto Ezincibilikayo: Isakhiwo esiqinile, esingaphumi emoyeni sikwazi ukumelana ngokwemvelo nokuhamba komoya futhi, ngendlela ebalulekile, nezikhukhula namafutha. Lokhu kuyimpahla ebalulekile yokusebenza.
4. Ukumelana Nokunisela: Nakuba ingavikeli amanzi, ubukhulu bayo obuphansi bwenza ukuthi ibe nokumelana okuthile nokuhamba komoya ongena.
Ukuqhathanisa: I-Supercalendering vs. I-Ordinary Calendering
Kubhalwe kahle ukuhlukanisa lokhu kokuhlelwa okujwayelekile okutholakala emashalofini ephepha amaningi:
Isici | I-Ordinary Calendering | Supercalendering (for Glassine) |
Rolls | Zonke izinsimbi ezigoqiwe | Izigubhu eziqinile zensimbi ezinzima nezithambile zecotton |
Isenzo Esiyinhloko | Ironing/Smoothing | Ukuphola, Ukuhlanganisa, kanye Nokuhlobisa Ngokuhlangana |
Umphumela kwiPapha | Ithuthukisa ukuhamba kahle nokukhanya kokuphrinta. | Kushintsha kakhulu isakhiwo sephepha, ubukhulu, nokucaca. |
Umphumela | Standard glossy magazine paper. | Iphepha le-Glassine. |
Izicelo Ezivamile Zephepha Le-Glassine
Ngenxa yezici zayo ezihlukile, iglasi isetshenziswa ku:
- Packaging: Ngokudla okwakhiwe (amakhandlela, imikhiqizo ephekiwe), izimpawu, ama-envelopu, nemikhiqizo yokusetshenziswa ephezulu.
- Pharmaceutical: Njengophepha lokuhlanganisa noma i-release liner yemikhiqizo yezokwelapha enezinhlaka.
- Arts & Conservation: Njengeshidi yokuvikela izithombe, imisebenzi yobuciko, nemibhalo ekubambeni kwezinye izindawo noma ekugugumeni okuncane.
- Labels: Njengomugqa wokukhulula wezimpawu ezizenzekelayo (nakuba ngokuvamile kufakwe i-silicone ukuze kusetshenziswe lokhu okukhethekile).
Isifinyezo
Ngokuyinhloko, i-Glassine Supercalendering Process iyindlela yokuphothula ye-mechanical enezinga eliphezulu, eguqula iphepha elikhethekile elilungisiwe libe impahla ehlukile. Ngokusebenzisa i-supercalender ukufaka ingcindezi enkulu, ukungqubuzana, nokushisa, idala iphepha le-glassine—umkhiqizo ohlonishwa ngokuqina kwawo okuphezulu, ukukhanya okuphumelelayo, ukubonakala, nokumelana kwawo okujwayelekile nomoya kanye ne-grease.
