Ukusabela kweekhemikhali ezisisiseko ngexesha lokutya okunyibilikayo

Ngenkqubela phambili eqhubekayo yetekhnoloji, i-solventless lamination yamkelwa ngobuninzi bomenzi wepakethe oguquguqukayo.

Ukukhawuleza, kulula, ukuhambelana nokusingqongileyo, iindleko-esebenzayo ziluncedo lwe-solventless lamination.

Kubaluleke kakhulu kuthi ukuba sazi ukusabela kweekhemikhali ezisisiseko ngexesha le-solventless lamination yemveliso yobuninzi engcono.

Amacandelo amabiniUkuncamathelisa okunganyibilikiyoyenziwe nge-polyurethane (PU), i-PU yadityaniswa yi-isocyanate (-NCO) ebizwa ngokuba yi-A component, kunye ne-polyol (-OH) ebizwa ngokuba yi-B component.Iinkcukacha ngempendulo nceda ujonge apha ngezantsi;

I-reaction ephambili iphakathi kwe-A kunye ne-B, i-NCO ine-chemical react with -OH, ngexesha elifanayo, ngenxa yamanzi nayo ineqela elisebenzayo -OH, amanzi aya kuba ne-chemical reaction kunye ne-A component release i-CO.₂,Umoya omdaka.Kwaye i-polyurea.

I-CO₂ inokubangela ingxaki yeqamza kwaye i-polyurea inokubangela isitywina esichasene nobushushu.Ngaphandle kokuba ukufuma kuphezulu ngokwaneleyo, amanzi aya kusebenzisa inxalenye ye-A eninzi kakhulu.Isiphumo kukuba i-adhesive ayikwazi ukunyanga i-100% kwaye amandla okudibanisa aya kuncipha.

Ngamafutshane, sicebisa ukuba;

Ukugcinwa kwe-adhesive kufuneka kugcinwe kwindawo epholileyo, eyomileyo kude nokufuma

Iworkshop kufuneka igcine ukufuma phakathi kwe-30% ~ 70%, kwaye isebenzise i-AC ukulawula ixabiso lokufuma.

Ngaphezulu kukho ukusabela kwekhemikhali esisiseko phakathi kwezinto ezincamathelayo ezimbini, kodwa i-mono-component encamathelayo iya kwahluka ngokupheleleyo, siyakwazisa imono component chemical reaction kwixa elizayo.
