Cyanoacrylate guruu. Description, akafanana, kushandiswa

Pari, hapana munhu kushamiswa pachishandiswa dzakadai wechipiri cyanoacrylate guruu, nani aizivikanwa vatengi somunhu superglue. Ezvemutauro aya anoshandiswa nyore uye nokutsanya kubatana pakubhadhara siyana nezvinhu (simbi, matanda, girazi, mapurasitiki zvichingodaro).

A Nhoroondo shoma

cyanoacrylate namira yakavhurwa panguva Second World War, musayendisiti American Garri Kuverom. Aiita Eastman Kodak Company kuti pagadzirwe Camera. Munguva yehondo, musayendisiti mubasa pave pachena mapurasitiki, izvo zvinogona kushandiswa Manyiminya pamberi. The zvichiguma zvinhu haana yakakodzera basa. Rakanga chokuita nokuchinja ehupfumi apo unyoro: nefuma anova Sticky.

Yakanga chete pashure pemakore anopfuura gumi Coover aziva nefuma yaakasika anogona kubatsirwa vanhu. Pakutanga, zvakanga yaishandiswa chisimbiso ronda panguva yacho Vietnam War.

Kwapera gore, mumwe cyanoacrylate namira yave pamberi vanhu. Kubvira ipapo, iye anoramba ari kudiwa pakati vatengi.

Chemical urongwa divi

Huru zvinoriumba guruu - Cyanoacrylate, i.e. cyanoacrylic asidhi Esteri. uwandu Its anogona kusvika 90-99% yose inowanwa sezvamunoita.

Kuti Ester plasticizers anowedzerwa (kusvika 10%), thickening vamiririri, stabilizers, activators. Chimwe chinhu chinokosha ndechokuti namira harina zvokufembedzwa.

gluing muitiro pazvikanganiso cyanoacrylate anionic polymerization maitiro ane zvakaneta alkaline mumiririri (kazhinji mvura). Kana nhete paiva guruu (anosvika 1 mm), mwando mudenga uye pamusoro waakaita hukawanika, zviri zvinokwana kuita. Achifuridzirwa mwando stabilizer riri namira rinotsemuka. Izvi zvinopa pakutanga polymerization maitiro pakati hukawanika.

Optimum ezvinhu ndiwo nzvimbo tembiricha uye 40-60% mwando. Under izvi ezvinhu, mashoko Tinonyanya kubatsirwa, iyo inogona kupa cyanoacrylate namira. Application zvinoreva panguva yakaderera mwando kunotoreva nokuwedzera kuomesa nguva. Higher mwando kuchaita kuderera kunaka gluing, simba shoma.

Key ehupfumi

Cyanoacrylate namira (mutengo mukati rubles 500 paminiti 50 magiramu) - iri Hauoneki fuma ine simba kwakanaka, izvo haazombotaurwi pashure kuomesa. Rine zvinotevera hwokugadzira mashoko:

• Inoitwa zvachose nezvishoma.

• Pasina solvent.

• Viscosity iri anenge 1.5 zviuru cps.

The chikuru ehupfumi pamusoro namira akaoma:

• Husingakwanisi yakakwirira tembiricha (-refu kudziyisa 80 madhigirii kana 100 madhigirii kuti pfupi).

• Budirira yakaderera tembiricha (kubvisa madhigirii 20). zvinoderedza At dzakaderera tembiricha iri tensile simba.

• It inochengeterwa mumvura kwevhiki dzinoverengeka.

• Husingakwanisi zvokufembedzwa (acetone, doro, mafuta chicherwa, peturu, gwenya mafuta) uye nemakemikari. Musi adhesion simba alkaline sei.

• Holds mutoro 150-250 makirogiramu / masendimita ^3.

zvoupenyu chikumbiro

Cyanoacrylate guruu anowanzodanwa kushandiswa anokurumidza kubatanidza nonporous zvokuvakisa kuwedzera zvinhu redhiyo zvokushandisa, rabha sealants pahwindo (musuo) kuvhurika, vanomhanyisa chip, dunhu mapuranga, harnesses, mumwe nodes mu music zvikamu.

Imwe mhando "superglue", octyl-2-cyanoacrylate, nokuda rapidity yokumisa uye usingashandi toxicity rinoshandiswa kuvhiyiwa kurega ropa uye gluing maronda. Munguva ichangopfuura, zvakakwanisika kushandisa guruu nokuda mitswe.

In mhuri kushandisa superglue kuti nokuzadza mapfundo makatsemuka. Kuti izvi zvidaro, zvinonzi pamwe kubikira pasoda. The zvichiguma muvhenganiswa anoomesa nokukurumidza uye anotarisa akafanana epurasitiki.

Cyanoacrylate guruu anogona kunzi zvakasikwa mushonga. Rinoshandiswa munzvimbo dzese zvokurapa, kugadzirwa matoyi, ndege, motokari, matoyi, zvishongo, shangu, utsanana vazviziva, makambani anoshambadzira uye nevamwe vakawanda.

kushandiswa

Bonding hukawanika anofanira kusununguka kubva muguruva, nengura uye mafuta echitema. Means kunge ari nzvimbo tembiricha katakata. Unogona kushandisa cyanoacrylate guruu. The activator kungadiwa munyaya vanoshorwa ezvinhu, kufukidza maburi makuru. Rinogona kushandiswa kusvikira namira (unhani rimwe pechiso), uye pashure (pfapfaidzo namira).

Pane imwe penyika vakashandisa namira iri zviduku zvizhinji. Kuti vawane marongera yakachena inokwanisa kushandiswa munhu epurasitiki spatula. Over munzvimbo huru guruu akashandisa madonhwe. Uyezve, pose uye chokuita zvakasimba compressed.

Guruu anoomesa pa nzvimbo tembiricha. At 20 Celsius, zvinotora maminitsi mashomanana. Izvi zvinogona nokukurumidza kana paine hunyoro glued hukawanika.

"NeMagwaro kuti" guruu chete nomudzimai mumasekonzi. Fully namira Inoomesa pamusoro usiku panguva 20 madhigirii uye hama mwando kupfuura 55%.

tsaona dziviriro

All basa dzinoshandiswa cyanoacrylate guruu, inofanira kuitwa kunze. Jobs mukamuri anobvumirwa chete vakamanikidzwa kufefetedza.

Dzivisa kubatana namira paganda, maziso uye zvomudumbu hurongwa.

Kamwe akarapa, kuti namira ari chubhu haigoni kusvinwa nechisimba, kana unguided ndege anogona kupinda meso ako. Panyaya iyi, kuti mhino zvinyoronyoro yakabaiwa nembambo (nani - dzvuku-inopisa).

"Glued" minwe haumanikidzwi kubvarura simba kana akatema nebanga. Izvi zvichaita kunongokonzera kukuvara ganda. Nokuti zviitiko izvozvo, vachishandisa acetone (kana zvakadai) iiswe pamusoro napkin. Acetone kuchaita kunyevenutsa guruu, asi kwete pakarepo. Zvichatora nguva (munguva dzakaoma pamberi awa).

Kunyatsoteerera hazvitenderwi kana tichishanda pamwe namira kusakara donje mbatya (kunyanya magiravhusi). NeVadzidzi namira cellulose rinenge maitiro richiwanika ne kusunungurwa yakawanda kupisa. Izvi zvingaita kuti kutsva.
