Imiterere ya firime yaIkibahoimpuzu zirimo ibintu bibiri: gutwikira hamwe no gukama.
Gufatanya kw'ibara risize ikibaho
Intambwe yambere yo gufatana hagati yicyuma cya substrate yicyuma hamwe nigitwikirizo ni uguhindura ibara ryometseho ikibaho hejuru yubutaka.Ipitingi irashobora gusimbuza umwuka namazi yabanje kwerekanwa hejuru yicyuma.Muri icyo gihe, guhindagurika kwa solve hejuru yubutaka biganisha ku gusenyuka cyangwa kubyimba.Niba ibipimo bya solubitifike ya firime ikora ibisigazwa byamabara yatwikiriye ibara hamwe nubuso bwa substrate byatoranijwe neza, bizakora urwego rudasobanutse hagati yibara ryubatswe hejuru yubutaka hamwe na firime ya coating, Ibi nibyingenzi kugirango bifatanye neza.
Kuma B.Ikibahogutwikira
Iyubakwa rya adhesion ryububiko bwibara ryuzuye ryuzuza gusa intambwe yambere yo gushiraho firime mugikorwa cyo gutwikira ikibaho cyometseho amabara, kandi inzira yo guhinduka firime ihamye ikeneye gukomeza, ishobora kurangiza inzira yose yo gushiraho firime.Inzira yo guhinduka kuva "firime itose" ikahinduka "firime yumye" mubisanzwe bita "gukama" cyangwa "gukiza".Iyi nzira yo kumisha no gukiza niyo ntandaro yo gutunganya firime.Ipitingi ifite uburyo butandukanye hamwe nibihimbano bifite uburyo bwihariye bwo gukora firime, bigenwa nimiterere yibintu bikora firime bikoreshwa mugutwikira.Mubisanzwe, tugabanya uburyo bwo gukora firime yo gutwikira mubyiciro bibiri:
(1) Kudahinduka.Mubisanzwe, bivuga uburyo bwo gukora firime yumubiri, bushingiye cyane cyane ku guhindagurika kwumuti cyangwa ibindi bitangazamakuru bikwirakwiza muri firime ya coating, buhoro buhoro byongera ubwiza bwamafirime yerekana kandi bigakora firime ikomeye.Kurugero, ibishishwa bya acrylic, chlorine ya chlorine, ibara rya Ethylene, nibindi.
(2) Guhinduka.Mubisanzwe, bivuga kubyerekeranye na reaction yimiti mugihe cyo gukora firime, kandi igifuniko gishingiye cyane cyane kumiti kugirango ikore firime.Ubu buryo bwo gukora firime bivuga polymerisation yibintu bikora firime mubitambaro, bita polymers, nyuma yo kubisaba.Birashobora kuvugwa ko ari uburyo bwihariye bwo guhuza polymer, bukurikiza byimazeyo uburyo bwo gukora polymer synthesis.Kurugero, alkyd coatings, epoxy coatings, polyurethane coatings, fenolique coating, nibindi. Ariko, imyenda myinshi igezweho ntabwo ikora firime muburyo bumwe, ahubwo yishingikiriza kuburyo bwinshi kugirango amaherezo ikore firime, kandi coil coil ni ubwoko bwa firime bushingiye kuburyo bwinshi kugirango amaherezo akore firime.
