Izikrini zoomatshini boShicilelo: Amacandelo angundoqo kwiiNkqubo zoShicilelo oluPhezulu

Amacandelo anguNdoqo weeNkqubo zoShicilelo oluPhezulu

Intshayelelo:

Oomatshini bokushicilela badlala indima ebalulekileyo kwihlabathi lanamhlanje, beququzelela ukuveliswa kwentaphane yezinto ezishicilelweyo esizifumana mihla le. Emva kwemiboniso, ezi nkqubo zoshicilelo zihambele phambili ziqulathe amacandelo abalulekileyo asebenza kunye ngaphandle komthungo ukwenza ushicilelo olukumgangatho ophezulu. Phakathi kwala macandelo, izikrini zomatshini wokushicilela zibambe ukubaluleka okungenakuphikiswa. Kweli nqaku, siza kuphonononga kumacandelo aphambili eenkqubo zoshicilelo oluphambili, sikhanyise ngokubaluleka kunye nokusebenza kwezikrini zomatshini wokushicilela.

1. Ukuqonda izikrini zoomatshini bokushicilela

Izikrini zomatshini wokushicilela, owaziwa ngokuba yi-mesh screens okanye izikrini, ziyinxalenye ebalulekileyo yenkqubo yokushicilela. Ezi zikrini zenziwe ngomnatha olukwe ngobunono, owenziwe ngemathiriyeli efana nepolyester, inayiloni, okanye intsimbi engatyiwayo. Umnatha woluliwe uze uncanyathiselwe kwifreyimu eyomeleleyo, okwenza umphezulu wetaut osebenza njengesiseko senkqubo yokushicilela. Izikrini zemesh ziza ngobukhulu obahlukeneyo kunye nezibalo zemesh, ezivumela ukuguquguquka kunye nokwenza ngokwezifiso ngokweemfuno ezithile zoshicilelo.

Izikrini zomatshini wokushicilela zisebenza njenge-conduit yokudlulisela uyilo kwiindawo ezahlukeneyo. Babambe indima ebalulekileyo yokulawula ukuhamba kwe-inki kunye nokuqinisekisa ukuveliswa komfanekiso ngokuchanekileyo. Izikrini zokuprinta zinemingxuma emincinci, okanye imingxuma yokuvula, evumela i-inki ukuba idlule ngexesha lenkqubo yokushicilela. Ubalo lwemesh lumisela inani lokuvuleka nge-intshi nganye yomgca, okuphembelela inqanaba leenkcukacha kunye nesisombululo esinokufezekiswa.

2. Ukukhetha iMesh kunye nokwenza ngokwezifiso

Ukukhethwa komnatha ofanelekileyo wenkqubo yoshicilelo ekwinqanaba eliphezulu kubalulekile ukuphumeza umgangatho woshicilelo ofunekayo. Kukho izinto ezahlukeneyo ekufuneka ziqwalaselwe xa ukhetha umnatha ofanelekileyo, kubandakanya uhlobo lwe-inki esetyenzisiweyo, imathiriyeli engaphantsi, kunye neemfuno zokusombulula umfanekiso.

Ubalo lwemesh lubhekisa kwinani lemesh evulekileyo nge-intshi nganye yomgama. Ubalo oluphezulu lwe-mesh, olunje ngama-280 okanye 350, lukhethwa kuyilo oluntsonkothileyo noluneenkcukacha, ngelixa izibalo ezisezantsi ze-mesh, njenge-86 okanye i-110, zilungele ukuprintwa okungqindilili nokungacacanga. Oku kulungelelaniswa kuvumela izikrini zomatshini wokushicilela ukuba zifake uluhlu olubanzi lweemfuno zokushicilela.

Isixhobo somnatha sikwadlala indima ebalulekileyo kwinkqubo yoshicilelo. Izikrini ze-polyester mesh zithandwa ngenxa yokufikeleleka kwazo, ukuqina, kunye nokuxhathisa imichiza. Izikrini ze-nylon mesh, kwelinye icala, zibonelela nge-elasticity ebalaseleyo kwaye zifanelekile kwizicelo ezifuna ukolula kunye noxinzelelo. Izikrini ze-mesh zensimbi ezingenasici zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zithengi.

3. Indima yeTension kunye neSqueegee Pressure

Ukufumana ukuxinana okungaguqukiyo kuyo yonke isikrini somatshini wokushicilela kubalulekile ukuze kuqinisekiswe iziphumo ezichanekileyo zoshicilelo. Uxinzelelo kumnatha wesikrini lumisela ulawulo kunye nokufana kokubekwa kwe-inki. Uxinzelelo olungonelanga lunokubangela ukuvuza kwe-inki okanye ushicilelo olungahambelaniyo, ngelixa uxinzelelo olugqithisileyo lunokubangela umonakalo ophambi kwexesha kwaye luchaphazele ukubhaliswa komfanekiso.

Ukufezekisa kunye nokugcina uxinzelelo olufunekayo, iisistim zoshicilelo ezihambele phambili zisebenzisa izixhobo zokucinezela ezolula izikrini zemesh ngokufanayo. Ezi zixhobo zivumela uhlengahlengiso oluchanekileyo, ziqinisekisa ukuba uxinzelelo lusasazwa ngokulinganayo kwisikrini sonke. Ukugcina uxinzelelo yinkqubo eqhubekayo efuna ukuhlolwa ngamaxesha kunye nohlengahlengiso.

Ngokubambisana noxinzelelo, uxinzelelo lwe-squeegee luchaphazela inkqubo yoshicilelo. I-squeegee, i-rubber blade efakwe kwi-handle, isetyenziselwa ukufaka uxinzelelo kwi-inki kwi-mesh yesikrini, ukuyinyanzela ngokuvula i-mesh kwi-substrate. Uxinzelelo olufanelekileyo lwe-squeegee luqinisekisa ukuhanjiswa kwe-inki ngokufanelekileyo, ukuthintela ukopha kwe-inki okanye ukuhlambalaza. Ubuchule boxinzelelo lwe-squeegee bubalulekile ekuphumezeni ushicilelo oludlamkileyo noluchanekileyo.

4. I-Emulsion Coating kunye nokulungiswa koMfanekiso

Ngaphambi kokuba inkqubo yokushicilela iqale, isikrini se-mesh sifumana i-emulsion coating kunye nokulungiswa komfanekiso. I-Emulsion, i-substance-sensitive substance, isetyenziswe kwi-mesh surface, idala i-stencil eya kuvumela inki ukuba idlule kwiindawo ezithile ngexesha lokushicilela. Eli cwecwe lenziwe ngokubeka isikrini somnatha ogqunyiweyo kukukhanya kwe-ultraviolet (UV) ngefilim elungileyo enoyilo.

Ukulungiswa komfanekiso kubandakanya ukulungisa uyilo olufunekayo okanye umsebenzi wobugcisa wokuprinta. Kwimeko yoshicilelo lwesikrini, oku kuhlala kubandakanya ukuguqula uyilo lube ngumfanekiso omnyama nomhlophe ochaseneyo ophezulu oza kusebenza njengefilimu entle. Ifilimu i-positive ibekwe phezulu kwesikrini esigqunyiweyo, kwaye ukukhanya kwe-UV ukukhanya kuqinisa i-emulsion kwiindawo ezihambelana nezinto zoyilo.

Nje ukuba ukubonakaliswa kwe-UV kugqityiwe, isikrini sihlanjululwa ngamanzi, sisusa i-emulsion engabonakaliyo kwaye sishiya ngasemva i-stencil echanekileyo kumphezulu we-mesh. Isikrini esifakwe i-emulsion-coated ngoku silungele ukusetyenziswa kwe-inki kunye nenkqubo yokushicilela ukuba iqalise.

5. Ukugcinwa kunye nokuphila ixesha elide

Ukuqinisekisa ixesha elide kunye nokusebenza ngokufanelekileyo kwezikrini zomatshini wokushicilela, ukugcinwa okufanelekileyo kubalulekile. Ukucocwa rhoqo kwezikrini emva kokushicilelwa ngakunye kunceda ukuthintela iintsalela ze-inki kunye ne-buildup ezinokuchaphazela ukuprintwa okulandelayo. Izisombululo zokucoca ezenzelwe ngokukodwa ukuprintwa kwesikrini zinconywa ukuba zigweme umonakalo kwi-mesh okanye i-emulsion.

Ukongezelela ekucoceni okuqhelekileyo, ukuhlolwa kwamaxesha kunye nokulungiswa kuyimfuneko ukujongana naziphi na iimpawu zokugqoka kunye nokukrazula. Izikrini zomnatha ezonakeleyo okanye ezikrazukileyo kufuneka zitshintshwe ngokukhawuleza okanye zilungiswe ukunqanda ukubeka esichengeni umgangatho woshicilelo. Ugcino olululo, olufana nokugcina izikrini zithe tyaba kwaye zikhuselwe eluthulini nakufuma, kwandisa ngakumbi ubomi bazo.

Isiphelo:

Izikrini zoomatshini bokushicilela ngokungathandabuzekiyo ziyinxalenye ebalulekileyo yeenkqubo zoshicilelo eziphucukileyo, zidlala indima ebalulekileyo ekuphumezeni ushicilelo olukumgangatho ophezulu. Ngolwakhiwo lwazo oluntsonkothileyo lwemesh, ezi zikrini zilawula ukuhamba kwe-inki, ziququzelela ukuveliswa komfanekiso, kwaye zenze ukuba uyilo oluchanekileyo luprintwe kwiindawo ezahlukeneyo. Ngokwenza ngokwezifiso okufanelekileyo, ukuxinezeleka, kunye nokugcinwa, ezi zikrini zinokuzisa ushicilelo olungaguquguqukiyo noludlamkileyo, luzenza zibe yimfuneko kurhwebo, ubugcisa kunye nosetyenziso lweshishini. Ke, kwixesha elizayo xa udibana noshicilelo olunomtsalane, thatha umzuzwana ukuxabisa umsebenzi ontsonkothileyo ophunyezwe zizikrini zoomatshini bokushicilela abasoloko bengahoywanga.
