Ukuphonononga izixhobo kunye noLwakhiwo lweeFilimu eziKhuselayo

Ifilimu yokukhusela i-aluminium yifomyula ethile yefilimu ye-polyethylene (PE) njenge-substrate, i-polyacrylic acid (ester) resin njengeyona nto iphambili yokuncamathela okunoxinzelelo, idityaniswe nezinto ezininzi ezincamathelayo ezincamathelayo ngokugquma, ukusika, ukupakisha kunye nezinye iinkqubo, ifilimu ekhuselayo ithambile, inamandla anamathelayo, kulula ukuyincamathelisa, kulula ukuyicoca. Uzinzo lokuncamathelisa uxinzelelo lulungile kwaye aluyi kuchaphazela kakubi umphezulu wemveliso oncamathiselweyo.

Ububanzi besicelo: Isetyenziswa kakhulu kuzo zonke iintlobo zeplastiki, ipleyiti yomthi (iphepha) ukhuseleko lomphezulu, njengePVC, PET, PC, PMMA ipleyiti enemibala emibini, ibhodi ye-foam ye-UV, iglasi, kunye nezinye iindawo zepleyiti kuthutho, ukugcinwa. , kunye nokucubungula, inkqubo yokufakela ngaphandle komonakalo.

Ulwakhiwo kunye nezinto eziphathekayo zefilimu ekhuselayo

Ifilimu ekhuselayo ngokuqhelekileyo ifilimu ekhuselayo ye-polyacrylate, ifilimu yokukhusela i-polyacrylate yesakhiwo esisisiseko ukusuka phezulu ukuya ngasezantsi: umaleko wokuzihlukanisa, umgca wokushicilela, ifilimu, i-adhesive layer.

(1, umaleko wodwa; 2, umaleko wokuprinta; 3, ifilimu; 4, umaleko oncamathelayo)

1. Ifilimu

Njengemathiriyeli ekrwada, ifilimu ngokuqhelekileyo yenziwe ngepolyethylene (PE) kunye ne-polyvinyl chloride (PVC). Ukubunjwa kwe-Extrusion, ukubunjwa kwesitofu, kunye nokubumba ukuvuthela kunokufumaneka. Njengoko i-polyethylene inexabiso eliphantsi kwaye ihambelana nokusingqongileyo, i-90% yefilimu yenziwe nge-polyethylene, kunye nenkqubo yokubumba njengento eyona nto iphambili. Kukho iintlobo ezininzi ze-polyethylene ezineendawo ezahlukeneyo zokunyibilika kunye noxinaniso.

2. I-Colloid

Iimpawu ze-colloid zinquma isitshixo kwizinto ezilungileyo nezimbi zefilimu ekhuselayo. Ifilimu ekhuselayo esetyenziswe kwi-adhesive-sensitive adhesive ineentlobo ezimbini: i-solvent-based polyacrylate adhesive kunye ne-adhesive polyacrylate ene-soluble yamanzi; baneempawu ezahlukeneyo.

I-adhesive-based polyacrylate adhesive

I-adhesive esekelwe kwi-solvent ye-polyacrylate yi-solvent ephilayo njengento ephakathi ukunyibilikisa i-acrylic monoma; i-colloid ibonakala ngokucacileyo, i-viscosity yokuqala iphantsi, kwaye ixhathisa kakhulu ukuguga ukuya kuthi ga kwiminyaka eyi-10 xa ibonakaliswe ekukhanyeni kwe-ultraviolet; i-colloid nayo iya kunyangwa kancinci. Emva kokuba ifilimu iphathwe nge-corona, i-adhesive ye-polyacrylate inokuthi ifakwe ngokuthe ngqo ngaphandle kwe-primer. I-adhesive ye-Polyacrylate iyinkimbinkimbi ngakumbi kwaye i-fluidity embi, ngoko i-adhesion yefilimu ekhuselayo idlala ngokukhawuleza; nasemva koxinzelelo, ijeli kunye nomphezulu oza kuthunyelwa awunakuqhagamshelwa ngokupheleleyo. Ibekwe emva kweentsuku ezingama-30 ~ 60, iya kudibana ngokupheleleyo nomphezulu oza kuthunyelwa ukuze kufezekiswe ukuncamathela kokugqibela, kwaye ukuncamathela kokugqibela kudla ngokuba kukhulu kunokuncamathela kwe-2 ~ 3 amaxesha, ukuncamathela ifilimu ekhuselayo, ukuba ifanelekile ukusika kwefektri yebhodi, umsebenzisi wokugqibela ukrazula ifilimu xa kukho Kunokuba nzima kakhulu okanye kungenakukrazulwa.

I-adhesive polyacrylate enyibilikayo ngamanzi

I-adhesive ye-polyacrylate enyibilikayo ngamanzi isebenzisa amanzi njengento ephakathi ukunyibilikisa i-acrylic monoma. Ikwanayo neempawu zokunamathela kwi-polyacrylate esekelwe kwi-solvent, kodwa i-colloid kufuneka igwenywe ukunciphisa ukudibanisa nomphunga wamanzi kunye nokukhusela i-glue eseleyo. Amazwe asakhasayo ahlala esebenzisa i-colloid ukuvelisa ifilimu yokukhusela ngenxa yokuba i-adhesive polyacrylate enyibilikayo emanzini ihambelana nokusingqongileyo kwaye ayifuni izixhobo zokubuyisela i-solvent.

3. Iimpawu ze-colloid

Ukuncamathela

Ibhekisela kwixesha apho ifilimu ekhuselayo evela kumphezulu ifakwe kumandla afunekayo ukuxobula. Amandla okubambelela ahambelana nezinto eziza kusetyenziswa, uxinzelelo, ixesha lokusetyenziswa, i-angle, kunye nobushushu xa uhlambulula ifilimu. Ngokutsho kweCoating Online, ngokubanzi, ngokunyuka kwexesha kunye noxinzelelo, amandla okubambelela nawo aya kunyuka; i-adhesion yefilimu ekhuselayo inokunyuka kakhulu ukuqinisekisa ukuba akukho ncamatheli eseleyo xa ukrazula ifilimu.Ngokuqhelekileyo, ukunamathela kulinganiswa ngovavanyo lwe-peeling ye-180-degree.

Umanyano

Ibhekisela kumandla e-colloid ngaphakathi, njengefilimu ekhuselayo yokubambisana kwe-colloid kufuneka ibe phezulu kakhulu; ngaphandle koko, ekukrazuleni ifilimu ekhuselayo, i-colloid iya kuqhekeka ngaphakathi, kubangele ukunamathela okushiyekileyo. Umlinganiselo wokubambisana: Ifilimu ekhuselayo iya kufakwa kwindawo yensimbi engenasici, kwaye ubunzima obuthile buya kuxhonywa kwifilimu ekhuselayo ukulinganisa ixesha elingakanani elifunekayo ukukhupha ifilimu ekhuselayo ngesisindo. Ukuba i-adhesive force inkulu kunamandla adibeneyo, krazula ifilimu ekhuselayo, kwaye i-adhesive molecules edibeneyo phakathi kwebhondi iya kwaphulwa, okubangela ukunamathela okushiyekileyo.

Ukuncamathela

Oku kubhekisela kumandla okudibanisa phakathi kwe-adhesive kunye nefilimu. Ukuba i-adhesion force inkulu kunamandla okubambisana, ukuba ifilimu ekhuselayo isusiwe, ibhondi phakathi kwama-adhesive molecule kunye nefilimu iya kuphulwa, kubangele ukunamathela okushiyekileyo.

Ukumelana ne-UV

I-adhesive ye-Polyacrylate yi-UV ukumelana, ifilimu ekhuselekileyo ye-polyacrylate ecacileyo kunye ne-UV stabilizer; Iyakwazi ukumelana ne-UV ukuya kuthi ga kwiinyanga ezi-3 ukuya kwezi-6. Ukusetyenziswa ngokubanzi kwezixhobo zokulinganisa imozulu ukuvavanya amandla e-UV efilimu ekhuselayo ngokulungelelanisa ubushushu bemitha yobushushu, kunye nokujiya ukuze kulinganiswe utshintsho lwemozulu rhoqo kwiiyure ezi-3 zokufuma okuphezulu kunye neeyure ezisi-7 zemitha ye-ultraviolet kumjikelo weeyure ezingama-50 zovavanyo. ilingana nokulingana nokubekwa ngaphandle kwenyanga enye.
