Cyanoacrylate iglu. Inkcazelo, ukwakheka, ukusetyenziswa

Okwangoku, akukho namnye uyamangala ngokusebenzisa ezifana kulu cyanoacrylate yesibini, eyaziwa ngcono kubaxumi njengoko ingcina. Ezi zixhobo zisetyenziselwa uqhagamshelwano elula fast kweentlobo ezahlukeneyo zemathiriyeli (intsimbi, umthi, iglasi, iplastiki, njalo njalo).

A incinane

cyanoacrylate ngcina yamiselwa ngethuba Second World War,-nzulu American Garri Kuverom. Wayesebenza e Eastman Kodak Inkampani ekuveliseni lekhamera. Ngexesha lemfazwe, isazinzulu inxaxheba kuphuhliso ngeplastiki ecacileyo, nenokuthi isetyenziswe emehlweni optical. Le zezinto ezithile eziziphumo lingakulungele nje ukuba umsebenzi. Kwakunxibelelene utshintsho kwiipropati xa ubumanzi: le nto iya iba ancamathelayo.

Yaba kuphela emva kweminyaka engaphezu kweshumi Coover waqonda iziyobisi wadala ngayo abantu. Ekuqaleni, oko lisetyenziselwa ukuvala inxeba ngexesha le-Vietnam War.

Emva konyaka, iglu cyanoacrylate sele thaca kuluntu. Ukususela ngoko, yena uhlala kwemfuno phakathi abathengi.

side imichiza

Eyona ingxenye main sikwi - Cyanoacrylate, ngamanye cyanoacrylic acid Ester. imali yayo besukelana 90-99% ye kuqamba iyonke.

Ukuze Ester plasticizers zongezwa (ukuya kwi-10%), ii-arhente ukudumba, ekwenzeni, activators. Into ebalulekileyo kukuba le ngcina ayiqulathanga izinyibilikisi.

inkqubo kuncanyatheliswe isekelwe phezu cyanoacrylate basabela polymerization anionic kunye arhente okwanamhlanje obrak (ngokuqhelekileyo amanzi). Xa maleko ubhityileyo kulu (ukuya ku-1 mm), ukufuma emoyeni naphezu imiphezulu semali, oko kwanele basabela. Phantsi impembelelo somfanekiso ukufuma ibekwe le ntaba kwakuse. Oku kunika ekuqaleni indlela polymerization phakathi iindawo.

iimeko elilelona ezi lobushushu igumbi kwaye 40-60% nokufuma. Phantsi kwezi meko, iziphumo kakuhle kufikelelwe, nto leyo ukunika iglu cyanoacrylate. Isicelo kuthetha ngexesha ukufuma ephantsi kubandakanya ukwanda kwexesha yokomisa. ukufuma ephakamileyo iza kuncipha umgangatho kuncanyatheliswe, amandla kunciphisa.

iipropati key

Cyanoacrylate ngcina (ixabiso ngaphakathi engange 500 50 grams) - into enemibala kunye livumba tyhafi, leyo liyalahleka emva omiswe. It zinedatha yobugcisa zilandelayo:

• It iqulathe nocatshulo eziqinileyo.

• Ngaphandle sijike.

• Viscosity nama-1.5 amawaka CPS.

Eyona engundoqo iimpawu iglu yomile;

• Resistant kumaqondo obushushu aphezulu (ixesha elide ukufudumeza ukuya degrees 80 okanye 100 degrees to ezimfutshane).

• Ukumelana amaqondo aphantsi (Degrees 20). Kwiqondo lobushushu asezantsi uqine kunciphisa.

• Igcinwe emanzini iiveki eziliqela.

• Ukumelana pende (acetone, utywala, izimbiwa oyile, ipetroli, i-oyile motor) kunye neekhemikhali. Kwi ngamandla adhesion umntu obrak zichaphazela.

• Ibamba umthwalo 150-250 kg / cm ^3.

enkulu isicelo

Cyanoacrylate sikwi ezininzi eziqhele ukusetyenziswa yoqhagamshelo ekhawulezayo izinto nonporous for obandayo iziqalelo kwezixhobo zerediyo, sealants irabha kwi window (emnyango) Ukuvula kwezimilo iitshiphusi, iibhodi beesekethe, eqinisa, nodes ngamnye kwiindawo sixhobo.

Olunye uhlobo "ingcina", octyl-2-cyanoacrylate, ngenxa wathandwa lolungiso yaye kuncinane zinetyhefu isetyenziswa utyando ukunqanda ukopha kunye kuncanyatheliswe amanxeba. Kutshanje, kwaba lula ukuba usebenzise iglu for waphuka.

Xa indlu sebenzisa ingcina zokugcwalisa amalungu kunye neentanda. Ukuza kuthi ga ngoku, oku kudityaniswe nesoda yokubhaka. Lo mxube ngenxa lukhuni ngokukhawuleza kakhulu kwaye ikhangeleka ngathi zeplastiki.

Cyanoacrylate iglu kunokuthathwa iyeza iphela. Oku kusetyenziswa kuzo zonke iinkalo amayeza, imveliso zokudlala, moya, izithuthi, izinto zokudlala, izacholo, izihlangu, xa zishishina zisithengisela nesempilweni, abarhwebi kunye nabanye abaninzi.

ukusetyenziswa

Imiphezulu ekwakheni ubuhlobo kufuneka bakhululeke eluthulini, mhlwa kunye namafutha amabala. Iindlela kufuneka kwiqondo lobushushu igumbi ubusuku bonke. Unga sebenzisa ngoko ingcina cyanoacrylate. Le isilumeki olunokufuneka kwimeko kweemeko ezingentle, yokugubungela izikhewu ezinkulu. Ingasetyenziswa de iglu (enamathela phezu komhlaba omnye), yaye emva (ngcina spray).

Kolunye ebusweni iglu isicelo ngezixa ezincinane. Ukuze ufumane umaleko acocekileyo ingasetyenziswa a spatula yeplastiki. Kwiindawo ezinkulu glue isicelo emanzini. Ngaphezu koko, umphezulu yaye enxulumene ngqongqo zixinaniswe.

Iglu lukhuni kwiqondo lobushushu igumbi. Xa degrees 20 Celsius, kuthatha imizuzu nje embalwa. Le nkqubo kukhawuleziswa xa kukho ukufuma njo indawo.

"Ucacelwe" iglu nje ezimbalwa lemizuzwana. Liqinisa kwakuse ngokupheleleyo phezu ebusuku ngama-20 kunye nokufuma ozalanayo mkhulu kwe-55%.

uthintelo ingozi

Wonke umsebenzi ezibandakanya ukusetyenziswa cyanoacrylate kulu, kufuneka wenziwe ngaphandle. Imisebenzi kweli gumbi kuvunyelwa kuphela umoya unyanzelekile.

Kuphephe ukuqhagamshelana iglu kakhulu eluswini, amehlo kunye nenkqubo yokwetyisa.

Xa wamphilisa, le ngcina kwi ityhubhu awukwazi oluphumayo ngaphandle ngenkani, okanye jet engakhokelwa unokufumana emehlweni akho. Kulo mzekelo, impumlo ababuleweyo ngobunono isikhonkwane (ngcono - red-etshisayo).

"Qhiwu" iminwe akuyomfuneko ukuqwenga amandla okanye usike ngemela. Oku kuya kukhokelela kuphela umonakalo isikhumba. Kuba Kwiimeko ezinjalo, esebenzisa acetone (okanye ezifana) zifakwe kwi neqhiya. Acetone uya athambise kulu, kodwa ngephanyazo. Kuya kuthatha ixesha elithile (kwiimeko ezinzima phambi kokuba iyure).

Ngokungqongqo engavunyelwa xa usebenza le ngcina banxibe zomqhaphu iimpahla (ingakumbi iiglavu). Xa umfowunelwa kunye iglu neselulosi ijwabu reaction oko kwenzeka nge kwakhululwa isixa esikhulu ubushushu. Oku kunokukhokelela nokutsha.
