Uburyo bwo gukiza

Uburyo bwo gukiza:

Gukiza ibifata bikorwa nuburyo bwumubiri, nko guhumeka kumashanyarazi, emulion coagulation hamwe no gukonjesha gushonga, nuburyo bwa chimique.

. Iyo ubushyuhe bwibidukikije buri hejuru, emulsion iba muri firime ikomeza ifata neza, mugihe iyo ubushyuhe bwibidukikije buri hasi hamwe na firime ntoya ikora ubushyuhe (MFT), hakorwa firime yera idahagarara. Ibikoresho bya Emulsion ahanini ni polyvinyl acetate hamwe na cololymers hamwe na acolylic acolylic.

. Mugihe uburemere bwa molekile bwiyongera, iminyururu ya molekile ihinduka kandi ikambuka - ihuza, ikora gel idashonga cyangwa gukomera kwibanze. Kongera igihe cyo gukira no kongera ubushyuhe bwo gukiza murwego runaka ntabwo bihwanye, kandi kugabanya ubushyuhe bwo gukiza biragoye kubyishyura mugihe kirekire. Kuberako imiti runaka ikeneye kubaho hagati yifatizo hamwe nubuso bwa aderend, ibi bisaba ubushyuhe bwo hejuru bihagije kugirango bikomeze.

Gukiza igitutu:

Nibyiza kubifata kugirango byinjire byuzuye hejuru; ni ingirakamaro mu gukuraho molekile nkeya ihindagurika ikorwa na adhesive curing reaction; ni byiza gukuraho ibishishwa bihindagurika bisigaye murwego rufatika; ni byiza kugenzura ubunini bwurwego rufatika; ibifata hamwe nubukonje bwinshi akenshi bigira ibice binini bifata neza, kandi ihinduka ryumuvuduko ukiza ugenzura ubunini bwurwego rwumuti.

Nyuma yo gushira kole, reka bicare umwanya muto, aribyo bita pre - gukiza. Iyo ubwiza bwa kole bwiyongereye, koresha igitutu kugirango umenye uburinganire bwurwego rwa kole.

Gukiza ubushyuhe:

Niba ubushyuhe bwo gukiza buri hasi cyane, umusaraba - uhuza ubucucike bwurwego rufatika ruri hasi cyane, kandi reaction yo gukira ntabwo yuzuye; niba ubushyuhe bwo gukiza buri hejuru cyane, biroroshye gutera kole gutakaza cyangwa gutuma igipande gifatika kivunika, bikaviramo kugabanuka kwingufu. Gushyushya bifasha gukwirakwiza molekile hagati yifatanije n’ibice bifatanye, bishobora gufasha gukora imiti ihuza imiti.

(1) Uburyo bwo gushyushya butaziguye mu ziko: Koresha igikoresho gihumeka kugirango umenye ubushyuhe bumwe.

(2) Uburyo bwo gushyushya hanze: Ubushyuhe bwimurirwa vuba imbere imbere yumutwe, bigabanya cyane igihe cyo gukira. Uburyo bwo gushyushya Ultrasonic: Irakwiriye gukiza ubushyuhe bwa viscoelastic yometse hamwe na solvent - ibifata byubusa, ariko ntibikwiriye kubikwa neza.
