Ukuprintwa kwe-pigment vs ukuprintwa kwedayi

Ukushicilela

Okubizwa ngokuba kukuprinta yinkqubo yokucubungula ukwenza idayi okanye ipeyinti kwi-paste yombala, ngokusetyenziswa kwendawo kwi-textile kunye neepatheni zokushicilela. Ukuze ugqibezele ushicilelo olulukiweyo, indlela yokucubungula esetyenziswayo ibizwa ngokuba yinkqubo yoshicilelo.

I-Pigment Printing

I-pigment printing yindlela yokushicilela apho i-pigment igxininiswe ngoomatshini kwilaphu ngokusebenzisa i-polymer ephezulu ye-molecular (i-adhesive) kunye nezinto ezinombala ezinganyibiliki emanzini (i-pigments) ukuze zenze ifilimu enemibala eqinile, ecacileyo kunye ne-wear-resistant kwilaphu.

Ukuprintwa kwedayi

Ngokwendlela yokwenza idayi yokudaya ifayibha, ukuprinta kunye nokudaya kuyafana, ngaphandle kokuba kushicilelo, idayi yombala othile isetyenziswa kwindawo yelaphu ngokweemfuno zepatheni, kwaye emva konyango oluthile, idayi. idayi i-fiber, kwaye ke iimveliso eziprintiweyo ezinombala omnye okanye ngaphezulu zifunyenwe kwi-textile. Ke ngoko, ukuprinta kunokuthiwa "kukudaya kwendawo".

Umgaqo wombala wepeyinti

Ukuprintwa kwe-pigment yindlela yokushicilela eyeka i-adhesive ekwenzeni ifilimu eqinile, ecacileyo kunye ne-resistant-resistant kwilaphu, ukuze kulungiswe ngomatshini ipeyinti kwilaphu.

Izinto zokufaka imibala kwiidayi

Ukudaya yinkqubo apho imathiriyeli yelaphu ifumana imibala eqaqambileyo neqinileyo ngokudityaniswa komzimba, imichiza okanye imichiza yendalo yedayi (okanye iipigments) kunye nemathiriyeli yelaphu.

Izinto eziluncedo nezingeloncedo

I-Pigment Printing

Izinto eziluncedo:

•Ukusetyenziswa okulula, inkqubo elula, imveliso ephezulu yabasebenzi, inokunciphisa ukukhutshwa kwamanzi amdaka

•Ichromatogram ebanzi, ukukhanya okuphezulu, imigca ecacileyo yokushicilela kunye neekhonto

•Ifanelekile kwiindlela ezikhethekileyo zokushicilela, kwaye ingasetyenziselwa ukukhupha kunye nokushicilela ukudaya

•Ukuthelekisa umbala ngokulula kunye nokuveliswa kokukhanya kombala olungileyo

•Ilungele ukuprintwa kwelaphu lezinto ezahlukeneyo zefiber, ngakumbi amalaphu adibeneyo.

Izinto ezingeloncedo:

• Ukungeva kakuhle kwezandla, ukomelela kakubi kunye nokukhawuleza ukuhlikihla okumanzi

• Ukusetyenziswa kwe-kerosene kwintlama e-emulsified kungcolisa umoya; Uninzi lweemonomers ezisetyenziselwa ukulungisa izinto zokuncamathelisa zinetyhefu

• Ukukhanya kombala akuqaqambi njengaleyo yoshicilelo lwedayi enesakhiwo esilinganayo

• I-adhesive kulula ukuyixobula kwaye ivale i-mesh

Ushicilelo lwedayi (uthatha iidayi ezisebenzayo njengomzekelo)

Izinto eziluncedo:

• Kukho iintlobo ezininzi, iichromatograms ezipheleleyo kunye nemibala eqaqambileyo

• Kukulungele ukulungiselela ukunamathiswa kombala, inkqubo yokushicilela elula, umphumo omuhle kunye neziphene ezimbalwa

• Ukukhawuleza okulungileyo kunyango olumanzi

• Ixabiso eliphantsi lokushicilela kunye nokudibanisa imibala ngokulula

Izinto ezingeloncedo:

• Uninzi lwazo alukwazi ukumelana neklorini, kwaye izinga lokulungisa liphantsi. Ezinye iidayi ezisebenzayo zinokuthe ngqo okukhulu (i-affinity), ekulula ukwenza ibala xa kusepha, ngakumbi xa kuprintwa imibala enzulu nengqindilili.

Umahluko:

Umahluko omkhulu phakathi koshicilelo lwedayi kunye noshicilelo lwe-pigment kukuba ukuprintwa kwe-pigment kudityaniswa nelaphu ngokuhlangana ngokomzimba, ngelixa ukuprintwa kwedayi kudityaniswa ngokuthe ngqo nelaphu ngu-van der Waals force.

Ushicilelo lwe-pigment lungasetyenziselwa ukusetyenzwa kwayo nayiphi na impahla yefayibha. Ineenzuzo ezininzi ekushicileleni imixube kunye neempahla eziphothiweyo. Inenkqubo elula, ichromatography ebanzi, ulwandlalo lwemilo yeentyatyambo ecacileyo, kodwa ukuvakala kwesandla esibi kunye nokukhawuleza ukuhlikihla okuphantsi. Ukukhawuleza kwabo ukukhanya kunye nokucocwa kokucoca okomileyo kulungile, nokuba kuhle kakhulu, ngoko ke basetyenziswa ngokubanzi kwiilaphu zokuhombisa, amalaphu amakhethini kunye neengubo zokugqoka ezifuna ukucocwa okomileyo.

Indlela yokwahlula phakathi koshicilelo lwedayi kunye nokuprintwa kwe-pigment

Ukuprintwa kwe-pigment kunye nokuprintwa kwedayi kunokwahlulwa ngokuthelekisa umahluko wobulukhuni phakathi kwenxalenye eprintiweyo kunye nenxalenye engashicilelwanga yelaphu elifanayo. Ukuvakala kwesandla kwindawo eprintiweyo yepeyinti inzima kancinci kunendawo engashicilelwanga, enokuthi ibe ngqindilili kancinci. Ukuba ilaphu liprintwe ngeedayi, akukho mahluko wobunzima obucacileyo phakathi kwenxalenye eprintiweyo kunye nenxalenye engashicilelwanga.
