Cyanoacrylate glue. Incazelo, ukubunjwa, ukusetshenziswa

Okwamanje, akekho kusimangaze izindlela ezifana yesibili cyanoacrylate glue, eyaziwa kangcono amakhasimende njengendlela superglue. Lezi amathuluzi asetshenziswa uxhumano elula fast ezahlukene izinto (metal, izinkuni, ingilazi, plastic kanye nokunye).

Umlando omncane

cyanoacrylate ingcina yasungulwa ngesikhathi seMpi yoMhlaba yesiBili, American Usosayensi Garri Kuverom. Wakusebenzela Eastman Kodak Inkampani ukwenziwa amakhamera. Ngesikhathi sempi, usosayensi othile wahlanganyela ukuthuthukiswa plastic ecacile, inqubo eyayingase isetshenziswe emehlweni optical. Indaba okuholela akumfanele umsebenzi. Kwakuhlangene ushintsho izakhiwo lapho umswakama: ketshezi kuba okunamathelayo.

Kwaba ngemva iminyaka engaphezu kweyishumi Coover waqaphela izidakamizwa edala kungabazuzisa kanjani abantu. Ekuqaleni, kwakusetshenziswa ukubopha inxeba ngesikhathi seMpi YaseVietnam.

Ngemva konyaka, i-ingcina cyanoacrylate seyenziwe esintwini. Kusukela ngaleso sikhathi, yena uhlala e funa phakathi abathengi.

inqubo yamakhemikhali uhlangothi

The main ingxenye glue - Cyanoacrylate, isb cyanoacrylic acid ester. senani bengase bazikhandlele 90-99% of the ukwakheka Imininingwane.

Ukuze ester plasticizers kunezelwa (kufika ku-10%), ama-ejenti ukuqina, stabilizers activators. Isici esibalulekile wukuthi kokokunamathisela ayiqukethe yokususa ingcekeza elenkani.

inqubo gluing kusekelwe cyanoacrylate polymerization anionic ukuphendula nge ejenti wavuma ane-alikhali (ngokuvamile amanzi). Lapho ungqimba elincanyana glue (kufika ku 1 mm), umswakama emoyeni futhi Laphezu zihlanganiswa, kwanele lokho ukusabela. Ngaphansi kwethonya umswakama isimame ise ezidabula ingcina. Lokhu kukunika kokuqala yokusabela polymerization phakathi evele.

izimo elikhulu kukhona igumbi lokushisa kanye 40-60% umswakama. Ngaphansi kwalezi zimo, imiphumela emihle siyithola, okuyinto anganikeza ingcina cyanoacrylate. Isicelo kusho ngesikhathi nomswakama aphansi kuhilelani ukwanda isikhathi omiswe. nomswakama Ephakeme uzokwehla izinga gluing, amandla incipha.

izakhiwo Key

Cyanoacrylate ingcina (intengo ngaphakathi ruble 500 ngalinye 50 amagremu) - into kungekho nto enemibala emihle nge iphunga eyethile, okuyinto ubalekela emva omiswe. It has idatha yomsebenzi osizayo alandelayo:

• Siqukethe ngokuphelele ukudla okuqinile.

• Ngaphandle kuphela.

• Viscosity cishe 1.5 izinkulungwane CPS.

I izakhiwo eyinhloko kokokunamathisela omisiwe:

• Amelana okushisa aphezulu (Ukushisa eside degrees 80 noma ama-degree 100 lemfishane).

• Abamelana okushisa aphansi (degrees 20). Emazingeni aphansi amandla eqine incipha.

• Lilondolozwe emanzini amasonto amaningana.

• Amelana kumakhemikhali awuketshezi (acetone, utshwala, uwoyela amaminerali, uphethiloli, uwoyela motor) namakhemikhali. On amandla adhesion a ane-alikhali nomthelela.

• Ubamba umthwalo 150-250 kg / cm ^3.

sphere kwesicelo

Cyanoacrylate glue ngokuvamile isetshenziselwa uxhumano esheshayo izinto nonporous lokukhuphula izakhi imishini radio, sealants iraba ewindini (umnyango) ukuvulwa, obandayo chips, wesifunda amabhodi, amahhanisi, isizinda ngabanye yomculo izingxenye.

Olunye uhlobo lokudla "superglue", octyl-2-cyanoacrylate, ngenxa rapidity kokubeka futhi sakugcina ubuthi isetshenziswa ukuhlinzwa ukuze kunqandwe ukopha futhi gluing amanxeba. Muva nje, sebekwazi ukusebenzisa glue ngoba waphuka.

Endlini zisebenzisa superglue ngokugcwalisa amalunga imifantu. Kuze kube yimanje, it is kuhlangene baking soda. Ingxube kwaphumela Uqinisa ngokushesha kakhulu futhi libukeka plastic.

Cyanoacrylate glue angabhekwa ikhambi jikelele. It is lisetshenziswe zonke izindawo imithi, ukukhiqizwa kwanoma amathoyizi, izindiza, izimoto, amathoyizi, imigexo, izicathulo, ware enelanga, ukukhangisa umkhakha nabanye abaningi.

ukusetshenziswa

Ubuhlobo obuseduze evele kumelwe abe umuntu okungekho uthuli, nokugqwala namafutha ndawo, kuzwakala. Kusho kumelwe abe ekamelweni lokushisa ngobusuku obubodwa. Ungasebenzisa glue cyanoacrylate. I Activator kungadingeka esimweni kwezimo ezingezinhle, ukumboza izikhala ezinkulu. Ingasetshenziselwa kuze ingcina (enamathela kwesinye surface), nangemva (spray Yesigcilikisha).

Ngesinye kobuso ingcina isicelo amanani amancane. Ukuze uthole ungqimba ehlanzekile engasetshenziswa spatula plastic. izindawo Over ezinkulu glue isicelo amathonsi. Ngaphezu kwalokho, ngaphansi komhlaba futhi axhunyiwe uvalwe onomfutho.

Glue Uqinisa emazingeni okushisa okuvamile. Ngezinye degrees 20 Celsius, kuthatha imizuzu embalwa nje. Le nqubo singasetshenziswa yashesha uma kukhona umswakama ethe njo evele.

"Uyakuqonda" glue nje ambalwa. Uqinisa ingcina ngokugcwele phezu ebusuku degrees 20 kanye nomswakama isihlobo mkhulu kunezinhliziyo 55%.

zokuvimbela ingozi

Zonke umsebenzi ezihilela ukusetshenziswa cyanoacrylate glue, kumelwe kwenziwe ngaphandle. Imisebenzi egumbini uvunyelwe kuphela ukupholisa bephoqeleka.

Gwema ukuthintana kokokunamathisela esikhumbeni, amehlo kanye isimiso sokugaya ukudla bungene.

Uma waphulukisa, kokokunamathisela tube ayikwazi kukhanywe ngenkani, noma jet unguided angangena amehlo akho. Kulokhu, ekhaleni ngobumnene wahlatshwa pin (kangcono - a red-hot).

"Ethe" iminwe akudingekile zokudonsa amandla noma usike ngommese. Lokhu kuyomane kuholele ekulimaleni kwesikhumba. Ukuze Ezimweni ezinjalo, usebenzisa acetone (noma efana) imali kwi napkin. Acetone ngeke ukuthambisa inhlaka, kodwa hhayi ngokushesha. Kuzothatha isikhathi esithile (sebunzimeni ngaphambili ihora).

Akuvumelekile lapho sihamba ingcina bafake ukotini izingubo (ikakhulukazi amagilavu). Ngo ukuxhumana ingcina cellulose izicubu ukuphendula kwenzeka nge ukukhululwa kwe semali ukushisa. Lokhu kungaholela ukusha.
