Ibintu bitatu by'ingenzi bigira ingaruka ku gukira

Igisubizo cyo gukiza ibifata ni inzira itera imbere kandi ikazamura imitungo nko guhuza imbaraga hakoreshejwe imiti (polymerisation na crosslinking). Gukiza nintambwe yingenzi kugirango ugere kubikorwa byiza bihuza; imbaraga ntarengwa zo guhuza zishobora kugerwaho gusa gukira kwuzuye. Kubijyanye no gukiza igihe, igabanijwemo ibyiciro bitatu: gukira kwambere, gukiza kwambere na post - gukiza.

Gukiza kwambere bivuze nyuma yigihe runaka mubushyuhe bwagenwe, kole ibona imbaraga, ubuso bwayo burakomera kandi ntibukomera, ariko ntiburakira neza.

Gukiza shingiro bisobanura nyuma yigihe kinini, amatsinda menshi yitabira kwitabira imiti kandi akagera kurwego runaka.

Inyandiko - gukiza bisobanura kuvura ibice byahujwe nyuma yo gukira shingiro kugirango utezimbere imikorere ihuza cyangwa wujuje ibisabwa. Mubisanzwe turabika kubushyuhe bwagenwe mugihe runaka. Iyi ntambwe yinyongera irangiza gukira, izamura urwego rwo gukira, ikuraho imihangayiko yimbere kandi ituma ubumwe bukomera.

Kugirango ubone iriba - ryakize kole, inzira yo gukira igomba kubaho mugihe gikwiye. Uburyo bwo gukiza ibifata bigira ingaruka cyane kubuziranenge. Hano haribintu bitatu byingenzi byo gukiza: ubushyuhe, umuvuduko nigihe. Ibi bintu bitatu bigira uruhare runini muburyo ibifatika bikiza.

Ibintu bitatu by'ingenzi bigira ingaruka ku gukira

1. Gukiza ubushyuhe nimwe mubintu byingenzi byingenzi byo gukiza. Niba ubushyuhe buri hejuru cyane, kole izatemba byoroshye cyangwa urwego rwa kole ruzavunika, bigabanya imbaraga zo guhuza. Niba ubushyuhe buri hasi cyane, molekile yibikoresho fatizo ntishobora kugenda mubuntu. Ibi biganisha ku bucucike buke no gukira kutuzuye. Tugomba rero kugenzura ubushyuhe cyane mugihe cyo gukira, kubera ko buri kibaho gifite ubushyuhe bwacyo bukiza.

2. Gukiza igitutu bisobanura gukoresha igitutu runaka mugihe cyo gukira kugirango ufashe kashe ya kole neza hamwe nibintu bifatanye kandi byemeze ubuziranenge bwiza, kandi ibifata bitandukanye bikenera umuvuduko utandukanye ushobora kugabanywamo ubwoko butatu: igitutu cyitumanaho gikoresha gusa uburemere bwibintu byahujwe nta muvuduko wongeyeho, bikwiranye na kole ya epoxy, α - cyanoacrylate glue, glue polyester glue na polyure; umuvuduko wa 0.1 ~ 0.3 MPa ikoreshwa kuri solvent - ibifatika bishingiye kuri fenolike - glue acetal, fenolike - nitrile butadiene glue, epoxy - nitrile butadiene glue, epoxy - nylon glue na polyimide; umuvuduko wa 0.3 ~ 0.5 MPa ni ya firime, ifu, tube, ibyuma bya pellet hamwe na kole ishushe, kandi umuvuduko mwinshi urashobora kuzamura ubushuhe bwabo.

3. Igihe cyo gukiza bivuga igihe gikenewe kugirango uhuze byuzuye munsi yubushyuhe nigitutu. Utubumbe dutandukanye dufite umuvuduko ukiza: α - cyanoacrylate kole hamwe na kole ishushe ikiza ako kanya; icyumba - ubushyuhe bwihuse - gukiza epoxy glue na kabiri - ibisekuru bya acrylic bifata amasaha menshi; epoxy polyamide kole ikenera iminsi myinshi kugirango ikire neza. Byongeye kandi, gukiza igihe bigira ingaruka kubushyuhe n'umuvuduko. Ubushyuhe bwo hejuru bugabanya igihe cyo gukira, mugihe ubushyuhe buke burayagura cyane, kandi kole zimwe ntizishobora gukiza iminsi iyo zibitswe munsi yubushyuhe bwicyumba.
