Iingcebiso kwi-UV yokuBonding Glass ukuya kwiMetal: ISikhokelo seNyathelo nenyathelo

Iglasi yokudibanisa i-UV kwintsimbi yinkqubo ebaluleke kakhulu kumashishini amaninzi, ukusuka kwimizi-mveliso kunye nokwakha ukuya kwiimoto kunye nakwindawo yomoya. Ikhono lokudala ikhonkco eliqinileyo, elisisigxina phakathi kwezi zinto zimbini kubalulekile ekudaleni uluhlu olubanzi lweemveliso - ukusuka kwiifestile kunye nezibuko ukuya kwizixhobo zonyango kunye namacandelo e-elektroniki.

Nangona kunjalo, ukudibanisa iglasi kwintsimbi kunokuba ngumngeni ngenxa yokungafani kweempawu zabo kunye neempawu zomphezulu. Iglasi idla ngokugqabhuka kwaye ithande ukuqhekeka, ngelixa isinyithi sinokutyibilika kwaye kunzima ukubambelela kuyo. Ukongezelela, inkqubo yokudibanisa idinga izixhobo ezikhethekileyo kunye nobuchule bokuqinisekisa umphumo oyimpumelelo.

Kweli nqaku, siza kubonelela ngesinyathelo ngesinyathelo isikhokelo kwi-UV yokudibanisa iglasi kwintsimbi. Iya kugubungela yonke into ukusuka ekulungiseleleni izinto ukuya ekuphiliseni ibhondi. Ngokulandela ezi ngcebiso kunye nokusebenzisa izixhobo ezifanelekileyo, unokufezekisa ibhondi eqinile, ethembekileyo ehlangabezana neemfuno zeshishini lakho kunye nezicelo.

Ukuqonda Izixhobo

Iglasi kunye nentsimbi zizinto ezimbini ezineempawu ezahlukileyo kakhulu, ezinokuthi zenze ukudibanisa kunye kube ngumngeni. Iglasi yimathiriyeli engeyiyo i-porous enendawo egudileyo kwaye imtyibilizi. Oku kwenza kube nzima ukuba i-adhesives idibanise. Ukongeza, iglasi inokuba brittle kwaye ithambekele ekuqhekekeni okanye ukwaphuka phantsi koxinzelelo. Kwelinye icala, isinyithi sinomgangatho orhabaxa kunye nerhasi ekwazi ukufunxa izinto zokuncamathelisa kakuhle, kodwa zinokutyekela kwi-oxidation kunye nokubola. Oku kunokuwenza buthathaka unxibelelwano ngokuhamba kwexesha.

Obunye ubuchule obube nempumelelo ekudibaniseni iglasi nentsimbi Ukudibanisa kwe-UV. Le nkqubo ibandakanya ukusebenzisa i-adhesive enyangekayo ye-UV efakwa kumphezulu weglasi kunye nentsimbi, ize inyangelwe kusetyenziswa ukukhanya kwe-UV. Ukudibanisa kwe-UV kunokudala ibhondi eyomeleleyo, esisigxina phakathi kweglasi kunye nesinyithi kuba inokungena kwindawo engekho-porous yeglasi kwaye ifikelele kwi-substrate yesinyithi. Ukongeza, inokudala ibhondi echasene nokutshintsha kobushushu, ukufuma kunye nezinye izinto zokusingqongileyo.

Imizekelo yeglasi kunye nendibaniselwano yentsimbi edla ngokudityaniswa ibandakanya:

• Glass-to-metal amatywina kwi-electronics kunye nezicelo zokukhanyisa, apho kukho ukudibanisa kweglasi ye-borosilicate kwintsimbi engatyiwayo okanye i-aluminiyam.
• I-Automotive glass bonding, apho iglasi epholileyo okanye e-laminated idibaniswe kwiifreyimu zetsimbi okanye izakhiwo.
• Ukwenziwa kwezixhobo zonyango, apho amalungu eglasi ahlala ebotshelelwa kwi-titanium, intsimbi engatyiwa, okanye ezinye iintsimbi.

Uhlobo lweglasi kunye nentsimbi esetyenziselwa ukudibanisa kunokuchaphazela inkqubo yokudibanisa. Ngokomzekelo, iglasi ye-borosilicate ixhaphake kakhulu ekwandiseni i-thermal kunye ne-contraction kune-soda-lime glass, enokuchaphazela ixesha lokunyanga kunye nokushisa kwe-adhesive. Ngokufanayo, iintsimbi ezithile, ezifana ne-aluminiyam, ziyakwazi ukubola ngakumbi kunezinye iintsimbi. Oku kunokuchaphazela ukuqina kwexesha elide lebhondi. Ukuqonda iipropathi zezinto ezidityanisiweyo kubalulekile ekufezekiseni ibhondi ye-UV eyimpumelelo.

 

Ukulungiselela iBonding

Ukucoca ngokufanelekileyo kunye nokulungiselela iglasi kunye nemigangatho yesinyithi phambi kokuba ukudibanisa kubalulekile ekufezekiseni ibhondi eqinile, ethembekileyo. Naluphi na ukungcola, ioli, okanye ezinye izinto ezingcolileyo eziphezu komhlaba zingaphazamisa i-adhesive kwaye zenze buthathaka ibhondi. Nantsi inyathelo ngenyathelo isikhokelo sokulungiselela umphezulu wokudibana kwe-UV:

 

Qokelela izixhobo eziyimfuneko: Uya kufuna ilaphu elingena-lint, utywala be-isopropyl okanye enye iarhente yokucoca efanelekileyo, kunye nomthombo wokukhanya kwe-UV.

 

Coca imiphezulu: Qala ngokusula iglasi kunye nemigangatho yentsimbi ngelaphu elingena-lint ukuze ususe nayiphi na inkunkuma. Emva koko, sebenzisa i-ejenti yokucoca kwilaphu kwaye usule phantsi iindawo kwakhona. Qinisekisa ukusebenzisa isisombululo sokucoca esifanelekileyo kwizinto eziboshwe, kwaye ulandele imiyalelo yokuvelisa.

 

Hlanza imiphezulu: Emva kokuba iindawo zosulwa phantsi kunye ne-ejenti yokucoca, zihlambulule ngamanzi acocekileyo ukususa nayiphi na intsalela.

 

Yomisa imiphezulu: Sebenzisa ilaphu elitsha elingena-lint ukomisa imiphezulu ngocoselelo. Oku kungenxa yokuba naluphi na umswakama oshiywe kwindawo enjalo unokuphazamisa i-adhesive kwaye wenze buthathaka ibhondi.

 

Jonga umphezulu: Ngaphambi kokuba usebenzise i-adhesive, jonga iindawo ezikufutshane ukuze uqiniseke ukuba zicoceke ngokupheleleyo kwaye akukho nakuphi na ukungcola.

 

Faka i-adhesive: Landela imiyalelo yomenzi wokusebenzisa i-adhesive kwiglasi kunye nemiphezulu yentsimbi. Qinisekisa ukusebenzisa i-adhesive ngokulinganayo kwaye ugweme ukusebenzisa kakhulu.

 

Lungisa ibhondi: Nje ukuba i-adhesive isetyenziswe, sebenzisa umthombo wokukhanya we-UV ukunyanga ibhondi. Landela imiyalelo yomenzi ngexesha lokunyanga kunye nobushushu.

Ukucoca ngokufanelekileyo kunye nokulungiselela umphezulu we-UV bonding kunganceda ukuqinisekisa ibhondi eyomeleleyo, ethembekileyo eya kuhlangabezana neemfuno zeshishini lakho kunye nezicelo.

 

Ukunyanga iBond

Ukukhanya kwe-UV yinxalenye ebalulekileyo yenkqubo ye-UV yokudibanisa, njengoko isetyenziselwa ukunyanga i-adhesive kunye nokudala iqhina olomeleleyo phakathi kweglasi kunye nentsimbi. Isibane se-UV sivuselela ii-photoinitiators kwi-adhesive, ibangele ukuba i-polymerize kwaye yenze ibhondi eyomeleleyo, ehlala ixesha elide.

Ixesha elifanelekileyo lokunyanga kunye nokuqina kubalulekile ekufezekiseni ibhondi ephumelelayo. Ukuba ixesha lokunyanga okanye ukuqina kuphantsi kakhulu, i-adhesive ayinakupholisa ngokupheleleyo, ekhokelela kwibhondi ebuthathaka. Ngakolunye uhlangothi, ukuba ixesha lokunyanga okanye ukuqina kuphezulu kakhulu, i-adhesive ingaba brittle kwaye ithande ukuqhekeka okanye ukwaphuka.

Ukwandisa inkqubo yokunyanga, kuyacetyiswa ukuba ulandele imiyalelo yomenzi we-adhesive esetyenziswayo. Kufuneka banike iingcebiso ezithile ngexesha lokunyanga kunye nokuqina okufunekayo ukufezekisa ibhondi eyomeleleyo. Kwakhona, kubalulekile ukusebenzisa umthombo wokukhanya we-UV ofanelekileyo ukuba i-adhesive isetyenziswe. Ezinye izinto zokuncamathelisa zifuna umthombo wokukhanya ophakamileyo we-UV kunezinye, ngoko ke kubalulekile ukukhetha eyona ilungileyo.

Ezinye izinto ezinokuchaphazela inkqubo yokunyanga ziquka ubukhulu bencamathelisa, umgama phakathi komthombo wokukhanya kwe-UV kunye nebhondi, kunye nobushushu kunye nokufuma kwendawo yokunyanga. Kubalulekile ukuqwalasela zonke ezi zinto xa ulungiselela inkqubo yokunyanga ukuze ufumane iziphumo ezingcono.

isiphelo

Ngokusekwe koku ngasentla, kuyacaca ukuba iglasi ye-UV yokudibanisa kwintsimbi inokuba yinkqubo enzima. Nangona kunjalo, ngokulungiselela ngokufanelekileyo iindawo kunye nokuphucula inkqubo yokunyanga, kunokwenzeka ukufezekisa ibhondi eqinile, ehlala ixesha elide. Ngobuchule obufanelekileyo kunye nezixhobo, amashishini afuna i-glass bonding kwintsimbi anokuzuza kule ndlela ethembekileyo nesebenzayo.
