Cyanoacrylate gluu. Description, mejupụtara, ojiji, nke

Ugbu a, ọ dịghị onye na-idem dị otú ahụ dị ka nke abụọ cyanoacrylate gluu, mma mara ahịa dị ka a superglue. Ngwá ọrụ ndị a na-eji dị mfe ma na ngwa ngwa njikọ nke dị iche iche nke ihe (metal, osisi, iko, plastic na na).

A obere akụkọ ihe mere eme

cyanoacrylate nyagide e guzobere n'oge Agha Ụwa nke Abụọ, ndị American ọkà mmụta sayensị Garri Kuverom. Ọ rụrụ ọrụ na Eastman Kodak Company n'ihi na mmepụta nke ese foto. Na oge agha, a ọkà mmụta sayensị na-emekwa ụfọdụ na mmepe nke doro anya plastic, nke nwere ike ga-eji na ngwa anya n'anya. Ihe ihe onwunwe bụ adabara ọrụ. Ọ ejikọrọ na mgbanwe Njirimara mgbe mmiri: umi na-aghọ nke nnyapade.

Ọ bụ nanị mgbe ihe karịrị afọ iri Coover ghọtara na umi o kere nwere ike irite uru ndị mmadụ. Ná mmalite, ọ na-eji mechie ọnya n'oge nke Vietnam War.

A afọ mgbe e mesịrị, a cyanoacrylate nyagide a n'ihu ụmụ mmadụ. Kemgbe ahụ, ọ na-anọgide na ina n'etiti ndị na-azụ.

Chemical usoro n'akụkụ

The isi akụrụngwa mama - Cyanoacrylate, i.e. cyanoacrylic acid Ester. Ya ego nwere ike iru 90-99% nke ngụkọta mejupụtara.

Na Ester plasticizers na-kwukwara (ruo 10%), ndim mmadụ, stabilizers, activators. Otu ihe dị mkpa mma bụ na nrapado anaghị nwere solvents.

gluing usoro dabeere cyanoacrylate anionic polymerization mmeghachi omume na a weakly alkaline gị n'ụlọnga (na-emekarị mmiri). Mgbe a mkpa oyi akwa nke mama (ruo 1 mm), mmiri na ikuku na na o sie ebupụta, ọ bụ ezuru mmeghachi omume. N'okpuru nduzi nke mmiri stabilizer emi odude ke nyagide gbawara. Nke a na-enye mmalite nke polymerization mmeghachi omume n'etiti ebupụta.

Kacha ọnọdụ ndị ụlọ okpomọkụ na 40-60% iru mmiri. N'okpuru ọnọdụ ndị a, ndị kasị mma na-arụpụta na-enweta, nke ga-enye a cyanoacrylate nyagide. Ngwa pụtara na a ala iru mmiri abuana na-abawanye na ihicha oge. Higher iru mmiri ga ibelata àgwà nke gluing, ike mbelata.

Key Njirimara

Cyanoacrylate nyagide (price n'ime 500 rubles kwa 50 grams) - a colorless umi na a gwụrụ isi, nke kpamkpam mgbe ihicha. Ọ nwere ndị na-esonụ technical data:

• Ọ mejupụtara kpamkpam nke solids.

• Enweghị mgbaze.

• Viscosity bụ mkpokọta 1.5 puku cps.

Isi Njirimara nke mịrị amị nyagide:

• Eguzogide okpomọkụ (ogologo oge kpo oku 80 degrees ma ọ bụ 100 degrees na obere).

• Idi ala okpomọkụ (mwepu 20 degrees). Na ala okpomọkụ na ike ọdụdọ mbelata.

• Ọ na-echekwara mikpuru n'ime mmiri ruo ọtụtụ izu.

• Eguzogide solvents (acetone, na mmanya, ịnweta mmanụ, mmanụ ụgbọala, moto mmanụ) na kemịkal. Na adhesion ike nke a alkaline emetụta.

• Esetịpụ ibu nke 150-250 kg / cm ^3.

nọ nke ngwa

Cyanoacrylate mama na-akacha eji maka ngwa njikọ nonporous ihe maka arịọnụ ọcha nke redio ngwá, roba sealants na window (ụzọ) mmeghe, arịọnụ ibe, circuit mbadamba, iche, onye ọnụ na ngwá akụkụ.

Otu ụdị "superglue", octyl-2-cyanoacrylate, n'ihi na rapidity nke mwube na ntakiri toxicity na-eji na ịwa ahụ iji kwụsị ọbara ọgbụgba na gluing ọnyá. Nso nso a, ọ ghọrọ kwere omume iji mama maka fractures.

Na ezinụlọ iji superglue n'ihi na ejuputa nkwonkwo na cracks. Iji mezuo nke a, ọ na-achọkwa na mmiri soda. Ihe ngwakọta siri ike ngwa ngwa na anya dị ka plastic.

Cyanoacrylate mama ike-atụle a eluigwe na ala usọbọ. Ọ na-eji na ebe niile nke nkà mmụta ọgwụ, na mmepụta nke ụmụaka ji egwuri egwu, ugbo elu, akpakanamde, ụmụaka, ọla, akpụkpọ ụkwụ, ịdị ọcha ike, ụlọ ọrụ mgbasa ozi na ọtụtụ ndị ọzọ.
