Tus kheej -crosslinking acrylic resin yog ib yam tseem ceeb ntawm kev khi hauvluam ntawv inks. Nrog rau tus yam ntxwv uas nws cov saw hlau molecular tuaj yeem ua rau nws tus kheej- sib cuam tshuam cov kev cuam tshuam los tsim ib qho peb- cov qauv kev sib txuas, nws ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm tus number case. Nyob rau tib lub sijhawm, nws muaj qee qhov kev thov tsis txaus vim qhov kev txwv ntawm nws tus kheej cov qauv tshuaj. Nws qhov zoo thiab qhov tsis zoo yog cuam tshuam nrog cov ntawv thov tiag tiag ntawm cov ntawv luam ntawv.
I. Core Advantages
1. Sib npaug adhesion thiab mechanical zog los daws qhov tsis sib haum xeeb ntawm cov khoom qub:
Ib txwm linear acrylic resins yog qhov nyuaj rau kev sib npaug ntawm qhov adhesion rau tsis yog -polar yas substrates (xws li BOPP thiab PET) thiab hnav tsis kam ntawm cov ntawv luam tawm. Txawm li cas los xij, tus kheej -crosslinking acrylic resins tuaj yeem ua tiav cov yam ntxwv ntawm cov tub ntxhais mos thiab lub plhaub tawv lossis cov tub ntxhais tawv thiab cov plhaub mos los ntawm kev kho cov iav hloov kub (Tg) ntawm cov tub ntxhais thiab plhaub txheej los ntawm cov tub ntxhais- plhaub qauv tsim. Nws tsis tsuas yog ua kom cov adhesion zoo ntawm qis-Tg tivthaiv rau lub substrate, tab sis kuj txhim kho cov cwj mem hardness thiab hnav tsis kam ntawm cov ntawv luam tawm los ntawm qhov siab -Tg tivthaiv, zam cov teeb meem ntawm kev khawb yooj yim ntawm cov khoom luam tawm thiab yooj yim tev ntawm ntug banding.
2. Cov dej zoo heev thiab cov kuab tshuaj tiv thaiv los txhim kho tus cwj mem ruaj khov:
Peb qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom tsim qauv tsim los ntawm tus kheej- cov tshuaj tiv thaiv kab sib txuas tuaj yeem tiv thaiv kev nkag mus ntawm cov dej thiab cov kuab tshuaj, thiab txhim kho cov dej tsis kam thiab hnyav ua haujlwm ntawm cov kua nplaum. Cov kev ntsuam xyuas qhia tau hais tias tus number case zaj duab xis nrog nws raws li lub binder tsis yooj yim rau ploj tom qab muab tso rau hauv dej rau 24 xuab moos, thiab qhov crosslinking℃kuaj los ntawm acetone immersion tuaj yeem ncav cuag 89.5%, uas tuaj yeem ua tau raws li cov kev xav tau ntawm cov dej tsis zoo xws li ntim khoom noj.
3. Tsawg- kub ceev kom qhuav thiab tiv thaiv ib puag ncig, haum rau ntau yam kev luam ntawv:
Qee tus kheej -crosslinking acrylic resins tuaj yeem kho sai sai rau hauv cov yeeb yaj kiab ntawm qhov kub qis dua 50 degree, nrog lub sijhawm ziab ntawm tsuas yog 25-50 vib nas this, uas yog tsim rau cov cua sov-sensitive substrates thiab siab- ceev luam ntawv cov kab ntau lawm, thiab tuaj yeem txhim kho kev ua haujlwm zoo. Nyob rau tib lub sijhawm, lawv feem ntau yog cov dej-dispersible systems, uas tuaj yeem txo qhov emission ntawm cov organic tebchaw (VOCs), thiab qee cov khoom siv cov kuab tshuaj zoo ib puag ncig uas tsis muaj ntxhiab tsw ntxhiab, nyob rau hauv txoj kab nrog kev txhim kho ntsuab ntawm kev lag luam number case.
4. Zoo luam ntawv adaptability, haum rau ntau yam substrates:
Cov pawg polar xws li carboxyl thiab hydroxyl pawg uas muaj nyob rau hauv cov resin molecules tuaj yeem txhim kho cov ntaub ntub dej thiab adhesion muaj peev xwm qis -polarity substrates xws li PE thiab PP, thiab adhesion ntawm PE thiab PP substrates tuaj yeem ncav cuag qib 0. Tib lub sijhawm, nws muaj cov yeeb yaj kiab zoo - tsim cov khoom xws li cov ntawv luam tawm, thiab qib defects. Cov ntawv luam tawm yog du thiab tiaj tus, thiab haum rau ntau txoj kev luam ntawv xws li gravure thiab flexographic luam ntawv.
5. Zoo cia ruaj khov thiab yooj yim siv:
Thaum lub sijhawm khaws cia, nws cov saw hlau molecular tuaj yeem nyob ruaj khov thiab tsis yooj yim rau kev sib txuas ntxov ntxov. Tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej alkaline, nws tuaj yeem yaj tag nrho hauv cov kuab tshuaj sib xyaw thiab tswj kom zoo dispersibility. Raws li tus number case binder, nws tuaj yeem sib xyaw sai sai nrog dej- raws li xim pastes thiab additives, nrog rau kev tsim kho yooj yim, thiab tuaj yeem hloov kho rau cov kev xav tau sib txawv los ntawm kev kho cov monomer piv, nrog rau kev siv dav.
II. Lub ntsiab tsis zoo
1. Cov txheej txheem npaj nyuaj thiab tus nqi siab:
Kev sib txuas ntawm tus kheej-crosslinking acrylic resin yuav tsum muaj kev tswj xyuas meej ntawm crosslinking monomer ntau npaum, core- plhaub qauv piv thiab cov tshuaj tiv thaiv, uas muaj cov kev xav tau siab rau cov khoom siv thiab thev naus laus zis. Tib lub sijhawm, qee qhov crosslinking monomers (xws li GMA) kuj kim heev, thiab cov ntsiab lus impurity yuav tsum tau tswj nruj me ntsis thaum lub sijhawm npaj, ua rau tag nrho cov nqi tsim khoom ntau dua li cov tshuaj linear acrylic resins, uas txwv tsis pub nws daim ntawv thov dav hauv nruab nrab - mus rau - qis - kawg inks.
2. Zaj duab xis yog nquag embrittlement thiab tsis txaus cuam tshuam:
Vim muaj zog rigidity ntawm peb -sib nqus qauv qauv, ib co self-crosslinking acrylic resins tsis elasticity tom qab tsim zaj duab xis thiab muaj peev xwm deformation tsis zoo. Thaum muaj kev cuam tshuam rau sab nraud, khoov lossis qhov kub thiab txias hloov pauv, qhov kev ntxhov siab sab hauv ntawm cov yeeb yaj kiab yog qhov nyuaj rau kev tso tawm, uas ua rau tawg lossis tawg. Ntxiv mus, qhov tuab ntawm zaj duab xis, qhov pom tseeb dua qhov tshwm sim ntawm embrittlement, uas tsis haum rau cov khoom luam tawm uas xav tau kev khoov ntau zaus (xws li kev ntim khoom yooj yim).
3. Txwv tsis pub mis compatibility thiab nquag mus rau theem sib cais:
Cov resin yog ib qho rhiab heev rau additives, pigments thiab cov kuab tshuaj nyob rau hauv tus number case formula. Yog tias cov mis tsis raug sib raug zoo, nws muaj teeb meem xws li emulsion agglomeration thiab particle loj nce (ntau tshaj 200nm), uas ua rau deterioration ntawm printing leveling. Nyob rau tib lub sijhawm, qee qhov tseem ceeb -cov khoom lag luam plhaub tau yooj yim rau kev sib sau ua ke hauv cov kuab tshuaj xws li ethanol vim yog cov yam ntxwv ntawm kev sib cais, cuam tshuam rau kev cia thiab siv kev ruaj ntseg ntawm tus number case.
4. Cov teeb meem seem thiab kev ua haujlwm tsis zoo:
Qee cov txheej txheem npaj siv cov tshuaj lom thiab tsw ntxhiab hloov cov tshuaj xws li tert -dodecanethiol, thiab cov seem yuav cuam tshuam rau cov neeg ua haujlwm tsim kho thiab ib puag ncig. Tsis tas li ntawd, yog hais tias tus crosslinking℃tsis tswj kom zoo, siab dhau heev lawm yuav ua rau kom txo tau cov resin yooj, thiab tsawg dhau yuav tsis ua tiav cov dej zoo tagnrho thiab hnyav hnyav. Tsis tas li ntawd, qee cov khoom muaj qhov tsis zoo resolubility thiab ua rau cov phaj txhaws, cuam tshuam rau kev luam ntawv txuas ntxiv.
