Yonke into omawuyazi malunga noxinzelelo lwe-Adhesives kwiFilimu eziKhuselayo

Isincamathelisi esinovakalelo loxinzelelo olusetyenzisiweyoIifilimu ezikhuselayo zingahlelwa zibe ziindidi ezine: irabha yendalo, irabha yokwenziwa, i-acrylic enyibilikayo emanzini, kunye ne-acrylic esekwe kwi-solvent. Isitshixo kwizinto ezilungileyo kunye ezimbi zefilimu ekhuselayo inqunywe yimpawu zokubambelela, ezineempawu ezahlukeneyo.

1. I-rubber yendalo inokubambisana okuphezulu, ngoko ngokuqhelekileyo ayivelisi iglue eseleyo. I-resin kunye nezongezo zilawula i-viscosity. Nangona kunjalo, inkqubo yokwaleka inzima ngakumbi; kuyimfuneko ukusebenzisa i-primer kwifilimu kuqala ukuphucula amandla omhlaba wefilimu ngaphambi kokuba i-rubber yendalo ifakwe kwifilimu ye-PE.Kwiindawo ezingaphakathi, irabha yendalo inokuhlala ingatshintshi ukuya kuthi ga kwiminyaka emibini, kodwa ithotywa kwaye iguge phakathi kweenyanga ezi-3-12 xa ibonakaliswe kukukhanya kwe-UV. Ifilimu ekhusela i-UV emnyama nemhlophe ngokuqhelekileyo yenziwe ngamacandelo amathathu: umaleko wangaphakathi, omnyama, unokufunxa ngokufanelekileyo imitha ye-ultraviolet; umaleko ophakathi, omhlophe, unokubonakalisa ukukhanya ukuze ifilimu ekhuselayo ingakwazi ukufunxa amandla amancinci, ukunciphisa ukuguga kwejeli, umaleko ongaphezulu: umhlophe: unokugubungela ngokupheleleyo umnyama womaleko wangaphakathi, umbala omhlophe ococekileyo unokuprintwa. intle ngakumbi. Ngoko nasemva kweenyanga ezili-12 zokuvezwa kwangaphandle, irabha ayiyi kuguga. Ukuphelisa iinkxalabo zabavelisi. Irabha yendalo eqhelekileyo inombala otyheli okhanyayo. I-adhesion yokuqala ye-rubber yendalo ilungile, kwaye kunzima ukutyhila i-glue kunye ne-adhesive ngokudibanisa omnye nomnye.

2. Irabha yokwenziwa inokubonelela nge-viscosity ephezulu kunye nokumelana nemozulu

I-rubber ye-Synthetic inokubonelela nge-viscosity ephezulu kunye nokuchasana kwemozulu, kodwa ixesha elide, iglue iya kuphiliswa, kwaye i-viscosity yokuqala iyancitshiswa, ngoko ke irabha yokwenziwa yongezwa ngokubanzi kwirubha yendalo.

3. I-acrylic e-soluble yamanzi ngamanzi njengento ephakathi ukunyibilikisa i-acrylic monoma

Njengobume bemekobume ngakumbi kwaye azidingi zixhobo zokubuyisela isinyibilikisi, amazwe asakhasayo adla ngokusebenzisa iicolloids ezinyibilikayo emanzini ukuvelisa ifilimu ekhuselayo. I-acrylic e-soluble yamanzi ineempawu zefilimu yokukhusela esekelwe kwi-solvent. I-adhesive surface yefilimu ekhuselayo e-soluble yamanzi kufuneka igweme kwaye inciphise ukudibanisa nomphunga wamanzi ukukhusela i-adhesive eseleyo. Ifilimu ekhuselayo e-soluble yamanzi ibonakala ngokukrazula okulula kakhulu kunye nokukhawuleza. Ifilimu yokukhusela i-acrylic e-soluble yamanzi e-United States nase-Asia eninzi.

4. i-acrylic esekwe kwi-solvent kukusebenzisa izinyibilikisi zendalo njengento ephakathi ukunyibilikisa i-acrylic monoma

I-adhesive ye-Acrylic iyabonakala kwaye iyamelana nokuguga ukuya kuthi ga kwiminyaka eyi-10. I-adhesive iphinda inyange kancinane xa ibekwe kwisibane se-UV. Xa kuthelekiswa nerabha, i-adhesives ye-acrylic ine-tack ephantsi yokuqala. Emva kokuba ifilimu iphathwe nge-corona, i-adhesive ye-acrylic ingasetyenziswa ngokuthe ngqo ngaphandle kwe-primer. Iifilimu ze-Acrylic zenza i-jittery, isandi esibuhlungu xa ukhulula, ngelixa iifilimu ezisekelwe kwirabha zikhulula ngesandi esithambileyo. Xa kuthelekiswa ne-adhesive ye-acrylic, irabha igudile kakhulu kwaye inomanzi. Emva koxinzelelo, ngokukhawuleza yenza uqhagamshelwano olupheleleyo kunye nomphezulu oza kufakwa, ngoko ke inzuzo ebaluleke kakhulu yefilimu yokukhusela yohlobo lwerabha kukuba i-adhesive ikhutshwa ngokukhawuleza, kwaye ukunamathela kokugqibela kufikeleleka ngokukhawuleza emva koxinzelelo lwe-roller. . Kufanelekile ukusika yifektri yebhodi kwaye ilungele kakhulu kumsebenzisi wokugqibela ukukrazula ifilimu. Kwimigangatho erhabaxa, emva koxinzelelo, iingenelo zokumanzisa kakuhle kweemolekyuli zerabha zibonakala ngakumbi; banokucinezelwa ngokukhawuleza kwii-depressions ezahlukeneyo kwaye babe noqhagamshelwano olupheleleyo kunye nomphezulu.

Irabha ye-acrylic inzima kwaye ihamba kakuhle, ngoko ke ukunamathela kwefilimu yokukhusela i-acrylic idlala ngokukhawuleza; nasemva koxinzelelo, ijeli kunye nomphezulu oza kuthunyelwa awunakuqhagamshelwa ngokupheleleyo. Kubekwe emva kweentsuku ezingama-30-60, kuya kudibana ngokupheleleyo nomphezulu oza kuthunyelwa ukuze kufezekiswe ukunamathela kokugqibela, kwaye ukunamathela kokugqibela kudla ngokuba kukhulu kunokubambelela kwi-viscosity yamaxesha angama-2-3.
