Ukukhethwa kwezinto zeleyibhile

Istikha esifanelekileyo kufuneka sisekelwe kwiimpawu zezinto ezikumphezulu kunye neglu, kunye noyilo lwembonakalo, ukufaneleka kokuprinta, isiphumo sokuncamathisela njengolawulo lwenkqubo, kuphela ukusetyenziswa kokugqibela okugqibeleleyo, ileyibhile ifanelekile.

1. Inkangeleko yeleyibhile

Injani imbonakalo yeleyibhile oyifunayo?
Akukho mbala:ecacileyo, ekhanyayo, ecacileyo ngokupheleleyo, ecacileyo kakhulu;
Umhlophe: umhlophe ocwebezelayo, umhlophe ongacwebezeliyo, umbala omhlophe;
Imibala yesinyithi: igolide ecwebezelayo, igolide engacwebezeliyo, igolide yesilika; isilivere ecwebezelayo, isilivere engacwebezeliyo, isilivere yesilika;
I-Laser: ihologram, ipateni yelaser.

Yintoni na le sicelo kunye nemo oyifunayo?
Ileyibhile yetyhubhu ethambileyo: Isigqubuthelo esipheleleyo esingu-370° (ukwahlulwa kugcinwe indawo yeoyile ecwebezelayo) Icala elingama-350° lingenanto;
Ukutywina: ukutywina kungenziwa kuphela emva kokuba kuncanyathiselwe kwaye kubekwe kubushushu begumbi obungaphezulu kwama-23℃ kangangeeyure ezingama-24 emva kokunyibilika.

Ingakanani ubungakanani beleyibhile?
Ukuqina: misela ngokuthe ngqo ubunzima kunye nomgangatho wokuncamathisela; Imilo kunye neempawu zezinto zokuncamathisela;
Ubukhulu: imisela ngokuthe ngqo ukuba ilebheli inokuncamathiselwa ngokuzenzekelayo na, kwaye ikwachaphazela nokuba ilebheli igobile na kunye nomgangatho wayo.

2. Izinto zomphezulu ezineelebheli ezifanelekileyo zokuprinta
Izinto ezincamathelayo ngandlela thile zithwala umfanekiso nolwazi, ngoko ke ukusombulula ukushicilelwa kwezinto ngumsebenzi wababoneleli bezinto. Iingxaki zomgangatho wokuprintwa kwe-inki ye-UV yefilimu ezincamathelayo zibonakala kakhulu kwi-inki emanzi kwaye i-inki iphuma, nto leyo ebangela ezi ngxaki zizizathu eziphambili zezi zinto zilandelayo:

Inqanaba lobuchule bomqhubi:Iintlobo ngeentlobo zezinto zokwakha, ubukhulu obahlukeneyo bomaleko we-inki kunye nomfanekiso owahlukileyo wokuprinta uneemfuno ezahlukeneyo zeyunithi yokomisa i-UV. Kwi-printing press, amandla okunyanga i-UV, isantya sokuprinta kunye nobukhulu be-inki zinokulungiswa, njengokuba umqhubi engakwazi ukujongana nolwalamano phakathi komnye nomnye, kuya kuchaphazela isiphumo sokomisa i-UV, isiphumo sokomisa sibonakalisa ngokuthe ngqo ukuhla kwe-inki.

Umgangatho we-inki:Ababoneleli nge-inki ye-UV bayanda kakhulu kwimarike, umgangatho awufani, kwaye umenzi ofanayo we-inki yemibala eyahlukeneyo isantya sokomisa kunye nenqanaba lokunyanga alifani. Ngenxa ye-inki ngokwayo, i-inki imanzi isoloko isenzeka (ingakumbi i-inki emnyama).

Izixhobo:Izixhobo zokuprinta, ingakumbi izixhobo ezibhityileyo, uxinzelelo lomphezulu walo sesona sizathu siphambili sokuchaphazela ukuqina kwe-inki, kodwa kwezinye izixhobo (ezifana ne-BOPP, i-PP, i-PET) zixhomekeke kuphela kuxinzelelo lomphezulu we-corona, azikwazi ukuhlangabezana neemfuno zokuprinta i-inki ye-UV.

3. Ipropati yezinto zokuncamathisela
Iimpawu ezahlukeneyo zezinto zokuncamathisela ziya kuba nefuthe elikhulu ekuncamathisweni kokugqibela kweleyibhile. Iimpawu ezahlukeneyo zineemfuno ezahlukeneyo kwi-adhesive.

Ukuba amandla omphezulu aphantsi, njenge-HDPE, i-LDPE, i-PP, njl.njl., iglue enamandla okuncamathelisa ayimfuneko.

Umzekelo, iibhotile zePET kunye neengxowa zePVC ezinamandla aphezulu omphezulu zincamathiselwe, ngenxa yokuba izinto ezincamathiselweyo zinobungqingqwa, kuyimfuneko ukuthintela ukuba i-glue ihlale kwizinto ezincamathiselweyo, ngoko ke i-glue enamatheleyo ngakumbi kufuneka ikhethwe.

Nokuba kukho i-plasticiser okanye i-stripper eninzi kakhulu kumphezulu wezinto ezincamathiselweyo, oko kuya kuchaphazela amandla okubopha kwe-glue.

Umphezulu orhabaxa wezinto ezincamatheliswayo, njengeebhotile ezithambileyo, ilaphu elingalukwanga, umphezulu orhabaxa weebhotile zePP kunye nePE, kufuneka ube neglue eguquguqukayo ephezulu.

4. Imilo ye-arc yezinto ze-paste
Umphezulu wokubhala iilebhile zezinto ezincamathiselweyo kufuneka ube tyaba xa uvuliwe. Ukuba zombini iindawo zokubhala iilebhile zigobile (umphezulu wokubhala iilebhile ojikelezayo) emva kokuba umphezulu wokubhala iilebhile wandisiwe, injongo yokubhala iilebhile ayinakuncamathiselwa kakuhle. Ke ngoko, umzimba webhotile kufuneka wenzelwe ukuphepha ukusetyenziswa kwemilo engaqhelekanga.

Emva kokususa imilo yomphezulu ongqindilili wokulebhelisha, i-radian enkulu, iimfuno zokuthamba kwezinto ziphezulu. Ukuthamba nokuqina ziindlela ezimbini zokubonakalisa ezifanayo.
