Ukupholisa okusabalele akuthinti kuphela ukuhamba kwawo wonke umuntu, kodwa futhi nokukhiqizwa kwezinqubo zokunyathelisa ngenxa yesimo sezulu esishisayo.Ngakho-ke, kulesi simo sezulu sokushisa esiphansi, yimiphi imininingwane okufanele inakwe ekunyatheliseni kokupakisha?Namuhla, u-Hongze uzokwabelana nawe ngemininingwane edinga ukunakwa ekuphrinteni nasekupakisheni esimweni sezulu esishisayo ~

Ukuvimbela Ukuqina Koyinki Wokuphrinta we-Rotary Offset
Kuyinki, uma kukhona ushintsho olubalulekile ekushiseni kwegumbi kanye nezinga lokushisa loketshezi lweyinki, isimo sokugeleza kweyinki sizoshintsha, futhi ithoni yombala nayo izoshintsha ngokufanele.
Ngesikhathi esifanayo, isimo sezulu esiphansi sezinga lokushisa sizoba nomthelela omkhulu kuzinga lokudlulisa uyinki ezindaweni zokukhanya okuphezulu.Ngakho-ke, lapho unyathelisa imikhiqizo ephezulu, kuyadingeka ukulawula izinga lokushisa nomswakama we-workshop yokunyathelisa kungakhathaliseki ukuthi yini.Ngaphezu kwalokho, uma usebenzisa uyinki ebusika, kuyadingeka ukuyishisa kusengaphambili ukuze unciphise ukushintsha kwezinga lokushisa kweyinki ngokwayo.
Qaphela ukuthi emazingeni okushisa aphansi, uyinki ugqinsile kakhulu futhi une-viscosity ephezulu, kodwa kungcono ukungasebenzisi ama-diluents noma uwoyela oyinki ukulungisa i-viscosity yawo.Ngoba lapho abasebenzisi badinga ukulungisa izici ze-inki, inani eliphelele lezithasiselo ezihlukahlukene ezingafakwa ku-inki eluhlaza okhiqizwe abakhiqizi beyinki lilinganiselwe, leqa umkhawulo.Ngisho noma ingasetshenziswa, yenza buthaka ukusebenza okuyisisekelo kweyinki futhi ithinte ikhwalithi yokuphrinta nobuchwepheshe bokuphrinta.
Isimo sokujiya kukayinki okubangelwa izinga lokushisa singaxazululwa ngalezi zindlela ezilandelayo:
1) Beka uyinki wangempela kurediyetha noma eduze kwe-radiator, uyishise kancane kancane futhi kancane kancane ubuyele esimweni sayo sokuqala.
2) Uma kunesidingo esiphuthumayo, amanzi ashisayo angasetshenziselwa ukufudumeza kwangaphandle.Indlela eqondile iwukuthela amanzi ashisayo endishini, bese ufaka ibhakede lokuqala (ibhokisi) likayinki emanzini, kodwa ukuvimbela umhwamuko ukuba ungangeni.Lapho izinga lokushisa lamanzi lehla lifinyelela kuma-degree Celsius angama-27, likhiphe, vula isivalo, bese ugovuze ngokulinganayo ngaphambi kokuwasebenzisa.Ukushisa kweshabhu yokunyathelisa kufanele kugcinwe cishe ku-27 degrees Celsius.

Sebenzisa i-antifreeze UV varnish
I-varnish ye-UV nayo iyinto ethinteka kalula ngamazinga okushisa aphansi, ngakho-ke abahlinzeki abaningi basebenza ngokukhethekile ekukhiqizeni izinhlobo ezimbili ezihlukene: ubusika nehlobo.Okuqukethwe okuqinile kwefomula yasebusika kuphansi kunaleyo yefomula yasehlobo, engathuthukisa ukusebenza kwe-varnish lapho izinga lokushisa liphansi.
Qaphela ukuthi uma ifomula yasebusika isetshenziswa ehlobo, kulula ukubangela ukuqiniswa kwamafutha okungaphelele, okungaholela ekubambeni kokunamathela nezinye izenzakalo;Ngokuphambene nalokho, ukusebenzisa amafomula ehlobo ebusika kungabangela ukungasebenzi kahle kwezinga likawoyela we-UV, okuholela ekukhihlizweni kwamagwebu nokuhluleka kwekhasi elolintshi.

Umthelela Wesimo Sezulu Sezinga Eliphansi Ephepheni
Ekukhiqizeni ukuphrinta, iphepha lingenye yezinto ezisetshenziswayo ezinezidingo eziphakeme kakhulu zokushisa kwemvelo kanye nomswakama.Iphepha liyi-porous material enesakhiwo esiyisisekelo esakhiwe imicu yezitshalo nezinto ezisizayo, ezine-hydrophilicity eqinile.Uma izinga lokushisa lemvelo kanye nomswakama kungalawulwa kahle, kungabangela ukuguqulwa kwephepha futhi kuthinte ukuphrinta okuvamile.Ngakho-ke, ukugcina izinga lokushisa elifanele lemvelo kanye nomswakama kuyisihluthulelo sokuthuthukisa ikhwalithi yokuphrinta iphepha kanye nokwenza ngcono ukusebenza kahle kokukhiqiza.
Izidingo zokushisa kwemvelo zephepha elivamile azibonakali kangako, kodwa lapho izinga lokushisa lemvelo lingaphansi kuka-10 ℃, iphepha elivamile liyoba "brittle" kakhulu, futhi ukunamathela koqweqwe lukayinki ebusweni bayo kuzokwehla ngesikhathi sokuphrinta, okuyisici. kulula ukubangela i-deinking.
Iphepha lekhadi legolide nesiliva livame ukukhiqizwa ngephepha elimbozwe ngethusi, iphepha lebhodi elimhlophe, amakhadibhodi amhlophe, nezinye izinto, bese lihlanganiswa nefilimu ye-PET noma i-aluminium foil.
Iphepha lekhadi legolide nesiliva linezidingo eziphakeme zokushisa kwemvelo ngoba kokubili izinto zensimbi nepulasitiki zizwela kakhulu ekushintsheni kwezinga lokushisa.Lapho izinga lokushisa lemvelo lingaphansi kuka-10 ℃, kuzothinta kakhulu ukufaneleka kwephepha lekhadi legolide nesiliva.Lapho izinga lokushisa lendawo yokugcina isitoreji sephepha lekhadi legolide nesiliva licishe libe ngu-0 ℃, ngemva kokuhanjiswa lisuka endaweni yokugcina impahla liyiswe endaweni yokusebenzela yokunyathelisa, kuzovela umhwamuko omkhulu wamanzi phezu kwawo ngenxa yomehluko wokushisa, othinta ukuphrinta okuvamile ngisho. okuholela emikhiqizweni kadoti.
Uma uhlangabezana nezinkinga ezingenhla futhi isikhathi sokulethwa siqinile, izisebenzi zingaqala ngokuvula ishubhu lesibani se-UV futhi zivumele iphepha lihambe lingenalutho kanye, ukuze izinga lokushisa lalo lilingane nezinga lokushisa elizungezile ngaphambi kokuphrinta okusemthethweni.
Ngaphezu kwalokho, ukomisa izinga lokushisa eliphansi, umswakama omncane olinganiselwe, nokushintshana komswakama phakathi kwephepha nomoya kungabangela ukuba iphepha lome, ligobe futhi lishwabane, kuphumele ekunyatheliseni kabi ngokweqile.

Umthelela Wezinga Lokushisa Eliphansi Kuzinto Ezinamathelayo
I-Adhesive iyi-ejenti yamakhemikhali ebalulekile ekukhiqizeni izimboni namuhla, futhi ukusebenza kwayo kuthinta ngokuqondile ikhwalithi yemikhiqizo yezimboni.
Inkomba ebalulekile yezobuchwepheshe ekukhiqizeni okunamathelayo ukulawula izinga lokushisa.Izinto ezisetshenziswayo zokunamathisela ama-polymers e-organic, ancike kakhulu ekushiseni.Lokhu kusho ukuthi izakhiwo zabo zemishini kanye ne-viscoelasticity zithinteka ngokushintsha kwezinga lokushisa.Kufanele kuphawulwe ukuthi izinga lokushisa eliphansi liyicala eliyinhloko elibangela ukunamathela kwamanga kokunamathela.
Lapho izinga lokushisa lehla, ubulukhuni be-adhesive buqina, bushintshe umphumela wokucindezeleka ku-adhesive.Esimweni esiphambene nokushisa okuphansi, ukunyakaza kwamaketanga e-polymer ku-adhesive kunqunyelwe, kunciphisa ukuqina kwayo.
