Cold welding yesimbi - mirayiridzo yekushandisa

"Cold welding" kana "Fast simbi" chishandiso chekunamira simbi, mapurasitiki, huni uye mamwe maficha. Izvo zvinofanirwa kucherechedzwa kuti hazvina chekuita nekuputika, sezvo kutonhora kwekushisa inzira yetekinoroji umo masimbi akabatana zvakasimba kune mumwe nemumwe semugumisiro wekumanikidzwa kwakananga uye deformation pasina kuwedzera tembiricha. Kubatana kunoitika pamwero wemolecular bond. Zvakanaka, "cold welding" glue yakagara ichinzi nekuda kwekuti seams inoramba iri pamusoro, sekunge mushure mekupisa kupisa.

Nokudaro, "Cold welding" inonamatira, iyo inosanganisira:

• epoxy resins;
• kuomesa;
• kushandura additives.

Epoxy resins haigadziri chisungo chakasimba kana ichiporeswa, uye saka mapurasitiki anowedzerwa kwavari kuti abatsire kutsungirira kuvhunduka uye kuzununguka mitoro, iyo inonyanya kukosha kana zvasvika pakugadzirisa zvinhu zvemuviri kana pasi pemotokari. Mukuwedzera, kusimba kwekubatana kunowedzera nekuwedzera simbi fillers inobva pane aluminium kana simbi.

Ichi chishandiso chinotengeswa chero muchimiro chechubhu, imwe ine chigadziko chekunamatira, uye imwe yacho ine yakaoma. Kana nenzira ye putty - maviri-layer cylindrical bars.

Mirayiridzo yekushandisa inotonhora welding

Usati wanamatira zvikamu zvesimbi, nzvimbo yavo inofanira kucheneswa zvachose chero tsvina uye guruva. Mushure meizvozvo, ivo vanofanirwa kuderedzwa nechero nzira iripo - solvent, doro, cologne.

Kana kutonhora kunopisa kuri mumachubhu, saka unofanirwa kusvina huwandu hunodiwa hweglue kubva kune imwe neimwe chubhu mumudziyo mumwe uye sanganisa zvakanaka kusvika homogeneous misa yaumbwa.

Izvo zvinodikanwa kugadzirira musanganiswa munzvimbo dzinofefetera, sezvo epoxy resin vapors inogona kutsamwisa mucous membranes yehuro nemhino.

Izvo zvinodikanwa kushandisa misa inoguma nekukurumidza sezvinobvira - zvichienderana nemugadziri, mukati me10-50 maminetsi. Iko ndiko kuti, kana basa guru rekugadzirisa richizoitwa, zvino zviri nani kushandisa welding muzvikamu zviduku, kana zvisina kudaro ichaoma uye isingashandisi.

Ipapo iwe unongoisa putty kune ese ari maviri, svina iwo zvishoma uye bvisa yakawandisa glue. Iyo nzvimbo inonamira pamwe chete zvakanaka uye haidi kudzvanyirirwa kune imwe neimwe nesimba rose. Ingosiya chikamu kuti chigadziriswe kusvikira adhesive seti. Izvi zvinogona kutora maminetsi gumi kusvika paawa.

Iyo glue inoomesa zvachose muzuva, saka siya chikamu chega kusvikira chaoma zvachose.

Putty "Cold welding"

Cold welding, iyo inouya nenzira yemabhawa, inonziwo putty, inoshandiswa kuvhara kuputika uye kuvhara maburi. Mukuenderana kwayo, inofanana neplasticine, saka yakanakira basa rakadaro.

Iwe unofanirwa kushanda nayo sezvinotevera:

• kuchenesa zvachose uye degrease nzvimbo dzinofanira kunama;
• cheka huwandu hunodiwa hweputty nebanga remafundisi;
• kanya iyo putty zvakanaka kusvika homogeneous epurasitiki misa yawanikwa (usakanganwa kupfeka magurovhosi erubha);
• iyo putty inogona kupisa panguva yekukanya - izvi zvakajairika;
• shandisa kune chikamu;
• kuti uenzanise mutsara, unogona kushandisa spatula, inofanira kunyoroveswa kuitira kuti putty isanamatira pairi;
• siya chikamu chega kusvikira putty yakaoma.

Dzimwe mhizha dzinokurudzira kudzvanya pasi kuti inamirwe pamwe chete nechirambi kana vice.

Chero zvazvaive, asi mushure mekusimba, girisi inova yakaoma sedombo. Ndapota cherechedza kuti zviri nyore kwazvo kubvisa glue kana putty neine inopisa solder iron kana banga rinopisa.

Zvinokurudzira zvekushandiswa kwechando welding

Sezvatinogona kuona, kutonhora kunotonhora kunotengeswa kana nenzira ye-adhesive-component adhesive, kana nenzira ye putty, inoyeuchidza plasticine mukuwirirana kwayo, iyo inokurumidza kuoma. Kuti uwane mhedzisiro yakanakisa, unofanirwa kufunga nezve kurudziro yemugadziri, saka glue rinoshandiswa kujoinha kana kuisa nzvimbo pamusoro peumwe neumwe, asi iyo putty inokodzera tee kana makona majoini. Izvo zvakare zvakanaka kwazvo kuvhara maburi akasiyana-siyana uye makatsemuka.

Kuwedzera mhedzisiro kana kana zvasvika kune yakakura nzvimbo yakagadziridzwa nzvimbo, iyo putty inoshandiswa neinosimbisa mesh kana fiberglass zvigamba.

Panyaya yekugadzira kuputika, migumo yavo inofanira kudirwa kuitira kuti kuputika kurege kukura. Vanoitawo zvimwe chetezvo kana vachigadzira makatsemuka pahwindo remota, izvo zvatatotaura nezvazvo pawebhusaiti yedu Vodi.su.

Ndokumbira utarise kuti inotonhora welding putty inogona zvakare kushandiswa kutsvedzerera kunze dents. Iwe unogonawo kuzadza dent neglue, kumirira kuti iome, uye ugoigadzirisa ne spatula duku.

Cold welding vagadziri

Kana tikataura pamusoro pevakagadziri uye mabhurendi chaiwo, isu tinokurudzira mabhureki anotevera.

Ndinovhura Simbi - Chigadzirwa cheAmerica chekirasi yepamusoro. Inotengeswa nenzira yemabhawa e-two-component putty, akazara mumidziyo yeplastiki cylindrical. Huremu hwechubhu imwe ndeye 57 gramu. Kuumbwa kweiyo epoxy adhesive kunosanganisira, kuwedzera kune plasticizers uye hardener, simbi mafirita, kuitira kuti Abro Steel inogona kushandiswa kugadzirisa:

• matangi emafuta;
• kutonhora radiators;
• pani dzemafuta;
• mufflers;
• block misoro uye zvichingodaro.

Inogona zvakare kushandiswa muhupenyu hwezuva nezuva, semuenzaniso, kuvhara makomba musimbi-plastiki kana simbi pombi, gluing aquariums, kugadzirisa maturusi uye zvimwe zvakawanda. Glue inopa yakanakisa kubatana patembiricha kubva paminus 50 degrees kusvika pamwe ne150 degrees. Inofanira kushandiswa maererano nemirairo iri pamusoro.

Poxypol - glue putty, inogona kushandiswa nenzira dzakawanda. Inoomesa nekukurumidza uye inopa yakasimba kwazvo inogoneka. Zvikamu zvakagadziridzwa zvinogona kudhonzwa uye kunyange tambo.

Diamond Press - Yakanyatsogadzirirwa kugadzirisa mota. Vanogona kugadzirisa kuputika mutangi, muffler, cylinder block. Mukuwedzera, inoshandiswa kuchengetedza nameplates - zviratidzo zvemugadziri. Iyo ine epoxy resins uye mafirita pane yakasikwa kana simbi hwaro.

Iwe unogonawo kutumidza mazita akawanda anozivikanwa: Blitz, Skol, Monolith, Forbo 671. Zvose zvinopa kubatana kwakavimbika, kunyange pasi pemvura. Kana iwe uri kugadzirisa zvikamu nenzira iyi, uye iwe uchida kuti kubatana kugare kwenguva yakareba sezvinobvira, tevera iyi mitemo iri nyore:

• kana ichipisa, glue ichaoma nekukurumidza uye inopa kunamatira kwakanaka, saka shandisa chivako chekuomesa bvudzi;
• nzvimbo dzinodziya panguva yekushanda pamusoro pemadhigirii zana hazvikurudzirwi kugadziriswa nenzira iyi - glue inokwanisa kumira kusvika kumadhigirii 100 ekupisa kwenguva pfupi, asi inodonha nekuratidzwa kwenguva refu;
• shandisa pane tembiricha iri pasi pemadhigirii mashanu Celsius hazvikurudzirwe;
• chengetedza inotonhora welding zviri nani pane tembiricha yemumba kure nezuva rakananga.

Kana iwe ukatenga inotonhora welding yezvido zveindasitiri, saka iwe unogona kuwana yakawedzera voluminous kurongedza. Semuyenzaniso, Metalox inotonhora welding inouya muhafu-lita magaba uye imwe yakadaro gaba inokwana kugadzirisa 0,3 square metres. surfaces. Iko kune zvakare kurongedza kwakanyanya - mumabhaketi esimbi e17-18 makirogiramu.

Sezvinopupurira maitiro uye ruzivo rwevatyairi vazhinji, kutonhora kwemoto kunopa kubatana kwakavimbika. Asi usakanganwa kuti iyi ndeimwe yemhando dze epoxy glue, kunyangwe nekuwedzera kwesimbi fillers. Naizvozvo, isu hatingakurudzire kutonhora kudziya kwekugadziriswa kwezvinhu zvakakosha zvemotokari uye magungano.

Vhidhiyo ine mazano uye musimboti wekushanda kwekutonhora welding.
