Cyanoacrylate ulimbo. Kufotokozera, zikuchokera, ntchito ya

Panopa, palibe kudabwa kudzera monga wachiwiri cyanoacrylate zomatira, imadziwika kuti makasitomala monga superglue a. Zida ntchito mogwirizana yosavuta ndi kudya a mitundu yosiyanasiyana ya zipangizo (zitsulo, matabwa, galasi, pulasitiki ndi zina zotero).

A mbiri pang'ono

cyanoacrylate zomatira unakhazikitsidwa pa Nkhondo Yachiwiri ya World, ndi American sayansi Garri Kuverom. Iye ankagwira Eastman Kodak kampani yopanga makamera. Pankhondo, wasayansi chinkhoswe mu chitukuko cha pulasitiki bwino, amene angagwiritsidwe ntchito pamaso kuwala. Nkhani chifukwa sanali oyenera ntchitoyo. Iwo anali wolumikizana ndi kusintha katundu pamene chinyezi: thunthu amakhala yomata.

Izo zinali kokha kwa zaka zoposa khumi Coover anazindikira mankhwala analenga tingapindule anthu. Poyamba, anali ntchito pomata chilonda pa nthawi ya Vietnam nkhondo.

Chaka chotsatira, ndi cyanoacrylate zomatira waperekedwa kwa anthu. Kuyambira pamenepo, iye zikufunika kwambiri pakati ogula.

mbali mankhwala ndondomeko

The chigawo chachikulu zomatira - Cyanoacrylate, i.e. cyanoacrylic asidi Ester. kuchuluka kwake akhoza kufika 90-99% ya kapangidwe okwana.

Kuti Ester ndi plasticizers akuwonjezeka (10%), otsatira thickening, stabilizers, activators. Chinthu chofunika kwambiri ndi zomatira lilibe solvents.

gluing ndondomeko zachokera cyanoacrylate anionic polymerization anachita ndi wothandizila ofooka zamchere (zambiri madzi). Pamene wosanjikiza zonyalazo zomatira (mpaka 1 mm), chinyontho mu mpweya ndi pa pamalo a akapolo, ndi chokwanira zotani. Mchikakamizo cha chinyezi stabilizer ili mu amang'amba zomatira. Izi zimamupatsa chiyambi cha polymerization anachita pakati pamalo a.

momwe akadakwanitsira ndi chipinda kutentha ndi 40-60% chinyezi. M'mikhalidwe awa, zingakuyendereni bwino, amene akhoza kupereka cyanoacrylate zomatira. Ntchito zikutanthauza pa chinyezi m'munsi zikuphatikizapo kuwonjezeka mu kuyanika nthawi. chinyezi apamwamba adzakhala ndichepe khalidwe la gluing, mphamvu amachepetsa.

katundu Ofunika

Cyanoacrylate zomatira (mtengo mkati rubles 500 pa magalamu 50) - ndi colorless mankhwala ndi fungo kukomoka, amene Mwamsanga pambuyo kuyanika. Ilo liri Zotsatira zolongosoka luso:

• Amakhala kwathunthu wa zolimba.

• Popanda zosungunulira.

• Kukhuthala pafupifupi 1.5 zikwi cps.

The katundu yaikulu ya zomatira zouma:

• Kugonjetsedwa ndi kutentha (yaitali Kutentha kwa madigiri 80 kapena madigiri 100 kwa lalifupi).

• Kupirira otsika kutentha (opanda madigiri 20). Pa kutentha m'munsi kwamakokedwe mphamvu amachepetsa.

• Izo awasungira kumizidwa m'madzi kwa milungu ingapo.

• Kugonjetsedwa solvents (acetone, mowa, mchere mafuta, mafuta, galimoto mafuta) ndi mankhwala. Pa guluu wolimba mphamvu ya zamchere zimakhudza.

• Akugwira katundu 150-250 makilogalamu / masentimita ^3.

dera ntchito

Cyanoacrylate zomatira ambiri amangoti ntchito zipangizo kugwirizana mwamsanga nonporous kwa zinthu za mawailesi, mankhwala ena omatira mphira ogwiritsa zenera (khomo) kutsegula, ukuonekera tchipisi, matabwa dera, zingwe, mfundo munthu m'madera chida.

mtundu wina wa "superglue", octyl-2-cyanoacrylate, chifukwa mofulumira lomanga ndi kochepa kawopsedwe ntchito opaleshoni kuti magazi asiye kutuluka ndi gluing mabala. Posachedwapa, zinali zotheka kugwiritsa ntchito zomatira kwa fractures.

M'banja ntchito superglue kwa kudzaza mfundo ndi ming'alu. Kuti zimenezi zitheke, iwo pamodzi ndi soda. The osakaniza chifukwa ikamauma mofulumira kwambiri ndipo zikuwoneka ngati pulasitiki.

Cyanoacrylate zomatira tinganene kuti mankhwala konsekonse. Izo ntchito m'madera onse a mankhwala, yopanga zidole, ndege, magalimoto, zidole, zodzikongoletsera, nsapato, ware ukhondo, amalonda ndi ena ambiri.

ntchito

Kogwirizana pamalo ayenera kukhala wopanda fumbi, dzimbiri ndi mafuta Madontho. Njira ayenera kukhala firiji usiku. Ndiye mukhoza kugwiritsa ntchito cyanoacrylate ulimbo. activator The ukafunidwe zinachitikira sinali bwino, kuphimba mipata yaikulu. Thiabendazole angagwiritsidwe ntchito mpaka zomatira (❖ kuyanika padziko wina), ndi pambuyo (kutsitsi zomatira).

Padziko mmodzi wa zomatira ntchito ndalama zazing'ono. Kuti mupeze wosanjikiza woyera angagwiritsidwe ntchito ndi spatula pulasitiki. Pa m'madera ambiri zomatira ntchito madontho. Komanso, pamwamba ndi kulumikizana mwamphamvu wothinikizidwa.

Zomatira ikamauma firiji. Pa madigiri 20 Celsius, pamafunika mphindi zochepa chabe. Ntchito imeneyi inapita patsogolo ngati pali chinyezi glued pamalo.

"Timamvetsa" ndi zomatira chabe angapo masekondi. ikamauma kwathunthu zomatira pa usiku pa madigiri 20 ndi chinyezi wachibale kuposa 55%.

ngozi kupewa

ntchito zonse zokhudza ntchito cyanoacrylate zomatira, ziyenela kuchitidwa panja. Jobs mu chipinda amaloledwa yekha ndi mpweya simuchita.

Musayandikire zomatira pa khungu, maso ndi dongosolo m'mimba.

Kamodzi wochiritsidwayo, zomatira mu chubu sangathe Finyani ndi mphamvu, kapena unguided ndege angakhoze kulowamo maso anu. Pankhaniyi, mphuno mokoma anamulasa ndi pini (bwino - wofiira otentha).

"Glued" zala Sikuti kugwetsera mphamvu kapena kudula ndi mpeni. Izi amadzachita kuwononga khungu. Pakuti Zikatero, ntchito acetone (kapena ngati) adayikidwa pa chopukutira ndi. Kafungo kabwino iodzafewa ndi zomatira, koma osati nthawi yomweyo. Kudzatenga nthawi (m'mikhalidwe yovuta m'mbuyomo ora).

Koletsedwa pamene ntchito ndi zomatira avale zovala thonje (makamaka Magolovesi). Pokhudzana ndi zomatira mapadi minofu anachita kumachitika ndi kutulutsidwa wambirimbiri kutentha. Zimenezi zingachititse kuti amayaka.
