Izikrini Zomshini Wokuphrinta: Kwembula Umnyombo Wobuchwepheshe Bokuphrinta Besimanje

Isingeniso:

Ubuchwepheshe bokuphrinta buhambe ibanga elide phakathi neminyaka edlule, bushintsha indlela esixhumana ngayo nokwabelana ngolwazi. Kusukela ezinhlotsheni zasendulo zokunyathelisa ngesandla kuye ezindleleni zokuphrinta zedijithali ezithuthukisiwe, imboni iye yabona intuthuko emangalisayo. Phakathi kwezingxenye eziningi ezakha umgogodla wobuchwepheshe besimanje bokunyathelisa, izikrini zemishini yokunyathelisa zidlala indima ebalulekile. Lezi zikrini ziwumnyombo wenqubo yokuphrinta, ezivumela ukunemba, ukunemba, nokuphumayo kwekhwalithi ephezulu. Kulesi sihloko, singena emhlabeni wezikrini zemishini yokuphrinta, sihlola ukubaluleka kwazo, izinhlobo, kanye nentuthuko kulo mkhakha.

Okuyisisekelo Kwezikrini Zomshini Wokuphrinta

Izikrini zomshini wokuphrinta, ezaziwa nangokuthi izikrini ze-mesh noma izikrini zokuphrinta, ziyingxenye ebalulekile yenqubo yokuphrinta. Lezi zikrini zenziwe ngemicu noma izintambo ezilukwe ngokuqinile, ngokuyinhloko ezakhiwe nge-polyester, inayiloni, noma insimbi engagqwali. Ukukhethwa kwezinto kuncike ezidingweni ezithile zomsebenzi wokuphrinta, njengokuhambisana kukayinki, ukumelana ne-solvent, nokuqina.

Isibalo semeshi sesikrini sibhekisela enanini lemicu iyintshi ngayinye. Izibalo eziphakeme ze-mesh ziphumela ekuphrinteni okuhle, kuyilapho izibalo ze-mesh eziphansi zivumela ukufakwa kukayinki owengeziwe, ofanele imiklamo egqamile nemikhudlwana. Isikrini se-mesh selulwe ngokuqinile phezu kohlaka, ngokuvamile esenziwe nge-aluminium noma ngokhuni, ukuze kwakheke indawo eyi-taut yokuphrinta.

Izikrini zemishini yokuphrinta azikhawulelwe ohlotsheni olulodwa. Izinhlobo zesikrini ezihlukene zenzelwe ukubhekelela izidingo ezithile zokuphrinta, ama-substrates, nezinhlobo zikayinki. Ake sihlole ezinye zezinhlobo ezijwayelekile zezikrini zomshini wokuphrinta ezisetshenziswa namuhla.

1. Izikrini ze-Monofilament

Izikrini ze-Monofilament yizikrini ezisetshenziswa kakhulu embonini yokunyathelisa. Njengoba igama liphakamisa, lezi zikrini zenziwe ngochungechunge olulodwa, oluqhubekayo. Zihlinzeka ngokugeleza kwe-inki okuhle kakhulu futhi zifanele izinhlelo zokusebenza eziningi zokuphrinta zenhloso ejwayelekile. Izikrini ze-Monofilament zinikeza ukulungiswa okuphezulu kanye nokwakheka kwamachashazi okunembayo, okuwenza afanelekele imiklamo eyinkimbinkimbi nemininingwane emihle.

Lezi zikrini zitholakala ngezibalo ezihlukahlukene ze-mesh, ezivumela amaphrinta ukuthi akhethe isikrini esifanelekile ngezidingo zawo zokuphrinta ezithile. Ngaphezu kwalokho, izikrini ze-monofilament ziqinile futhi zihlala isikhathi eside, ziqinisekisa ukusebenza okungaguquki phakathi nezikhathi ezinwetshiwe.

2. Izikrini ze-Multifilament

Ngokuphambene nezikrini ze-monofilament, izikrini ze-multifilament zakhiwe ngemicu eminingi elukwe ndawonye, ​​​​edala isakhiwo semeshi esijiyile. Lezi zikrini zivame ukusetshenziselwa ukuphrinta kuma-substrates angalingani noma amabi. Idizayini yezintambo eziningi inikeza amandla angeziwe nokuzinza, okuvumela ngisho nokufakwa kukayinki ezindaweni eziyinselele.

Izikrini ze-Multifilament ziwusizo ikakhulukazi uma usebenzisana noyinki onemibala enzima noma uphrinta ezintweni ezithungwe njengezindwangu noma izitsha zobumba. Imicu eminyene kumeshi iphumela ezikhaleni ezinkudlwana, yenza kube lula ukugeleza kukayinki futhi ivimbele ukuvaleka.

3. Izikrini Zensimbi Engagqwali

Kuzinhlelo zokusebenza zokuphrinta ezikhethekile ezidinga ukuqina okukhethekile kanye nokumelana namakhemikhali aqinile noma ukuchayeka isikhathi eside kumazinga okushisa aphezulu, izikrini zensimbi engagqwali yizona ezikhethwa kakhulu. Lezi zikrini zenziwe ngezintambo zensimbi engagqwali, zinikeza amandla okusebenza aphakeme nokuzinza.

Izikrini zensimbi engagqwali zivame ukusetshenziswa ezimbonini ezifana ne-electronics, izimoto, kanye ne-aerospace, lapho ukuphrinta kuvame ukudingeka kuma-substrates ayinselele noma ngaphansi kwezimo zemvelo ezinzima. Imvelo eqinile yezikrini zensimbi engagqwali iqinisekisa ukusebenziseka isikhathi eside kanye nemiphumela yokuphrinta enembile, ngisho nasezimweni ezinzima.

4. Izikrini ze-High Tension

Izikrini ezidonsa kanzima ziklanyelwe ukumelana nokushuba okukhulu phakathi nenqubo yokuphrinta. Lezi zikrini zelulelwe ngokuqinile kuhlaka, okuholela ekuncipheni okuncane noma ukuwohloka ngesikhathi sokuphrinta. Ukuqina okuphezulu kuvimbela i-mesh ukuthi inganyakazi noma inyakaze, okuholela ekubhaliseni okuthuthukisiwe kanye nekhwalithi yokuphrinta engaguquki.

Lezi zikrini zivame ukusetshenziswa emisebenzini yokuphrinta emikhulu, njengokuphrinta izibhengezo noma izinhlelo zokusebenza zezimboni, lapho ukunemba nokufana kubaluleke kakhulu. Ukuqina okukhuphukile okunikezwa izikrini ezidonsa kanzima kunciphisa amathuba okunwebeka noma ukugoba, okuqinisekisa ukuzinza okufanelekile kokuphrinta kanye nokuphila isikhathi eside okuthuthukisiwe.

5. Izikrini ezisebenzayo

Izikrini ezisebenzayo ziwuhlobo oluyinkimbinkimbi lwezikrini zomshini wokuphrinta olusebenza ngokususelwe ekuphenduleni kwamakhemikhali. Lezi zikrini zimbozwe nge-emulsion ye-photosensitive esabela ekukhanyeni kwe-UV. Izindawo ezichayeke ekukhanyeni kwe-UV ziyaqina, zenze i-stencil, kuyilapho izindawo ezingaveziwe zisala zincibilika futhi zigezeke.

Izikrini ezisebenzayo zinikeza ukulawula okunembile phezu kwenqubo yokudala ama-stencil, okuvumela imiklamo eyinkimbinkimbi enokulungiswa okuphezulu. Lezi zikrini zivame ukusetshenziswa ezinhlelweni ezidinga imininingwane ephezulu, njengokuphrinta kwebhodi lesifunda, ukuphrinta kwendwangu, kanye nemidwebo yezithombe ezisezingeni eliphezulu.

Isiphetho:

Izikrini zemishini yokuphrinta zidlala indima ebalulekile kubuchwepheshe besimanje bokuphrinta, zivumela ukuphrinta okucacile, okunembayo, kanye nekhwalithi ephezulu. Kusukela ezinhlobonhlobo zezikrini ze-monofilament kuya ekuqineni kwezikrini zensimbi engagqwali, izinhlobo zesikrini ezihlukene zibhekelela izidingo zokuphrinta ezihlukene. Ukwengeza, izikrini ezidonsa kanzima nezikrini ezisebenzayo zinikeza ukusebenza okuthuthukisiwe kwezinhlelo ezithile zokusebenza.

Njengoba imboni yokunyathelisa iqhubeka nokuvela, kanjalo nobuchwepheshe obulandela izikrini zemishini yokunyathelisa. Ukuthuthuka kwezinto zokwakha, amasu okumboza, nezinqubo zokukhiqiza kuzothuthukisa ukusebenza kwesikrini, kunikeze amaphrinta amandla amakhulu nokusebenza kahle. Ngokukhula njalo kwesidingo samaphrinti ekhwalithi, ukubaluleka kwezikrini zemishini yokuphrinta njengomnyombo wobuchwepheshe besimanje bokuphrinta angeke kweqiswe.
