Iglu "welding lokulayita": inkcazelo kunye neempawu

Iglu "welding lokulayita" yi sisincoko elungiselelwe indibano iinxalenye ngaphandle kwempembelelo thermal. Ekwakheni ubuhlobo ikhutshwa phandle deformation yeplastiki kunobukhulu kunye ukungena yalo komhlaba. Le ndlela ifumene ukusasazwa kwayo ngokubanzi kwi ngemibhobho kunye nemoto ukulungiswa. Lo mxube ineendlela ezininzi, phakathi leyo, umzekelo, nokungabikho imfuneko yoqeqesho.

incazelo

welding enamathelayo ebandayo kuba mnye-candelo okanye icandelwana-emibini. Ukubunjwa kungabandakanya nentlaka epoxy , amacandelo zesinyithi kunye nezinto abancedisayo. Kwimeko yokuqala sithetha izithako ezifunekayo ukudala ukufana kunye plasticity. Ukuba le nto ndiyibhalayo bako sisinyithi, benza njengoko a lokufaka. Nangona kukho into engaphezulu isalfure njalo njalo.

Iglu "welding ebandayo" - umnxube a izithako Polymer. Amandla kuya kuxhomekeka kumgangatho mxube, yokulungiselela komhlaba kunye nokusetyenziswa oluchanekileyo. Kufuneka uzame ukudala imeko efanelekileyo apho indawo uqhagamshelwano kufuneka longamele umbandela isiseko, kodwa practice ukufezekisa oku akusoloko kusenzeka. Ngoko ke, ukuba ukuchaza iglu lisetyenziswa kuphela ukulungiswa ezincinane.

iimpawu lobushushu

Lidla umboleki kuphakamisa umbuzo malunga nenqanaba lobushushu ukuze ube nako ukumelana nokwakheka ngcina. On iphakheji uyakwazi ukufumana ezithile parameters phantsi apho ukwakhiwa kuzakuhlala kuzinzile. Le mixube lobushushu kunokwenzeka uqoqosho iphezulu ngokuqhelekileyo ngu-260 ° C okanye noko ngaphezulu.

Nangona kunjalo, kufuneka kukhunjulwe ukuba umxube uya komelela kuphela xa zisetyenziswa ngokuchanekileyo. Oku kubonisa ukuba le ngcina kunye lobushushu encinane ubuninzi kufuneka isetyenziswe ukuba kutywinwe iintanda izinto eziza kusetyenziswa phantsi kweemeko eziqhelekileyo.

Emarikeni uyakwazi ukufumana ingcina oya kuba nako ukuyinyamezela lobushushu eliphezulu, oko kuthiwa-lobushushu eliphezulu welding ebandayo. ulwazi lwendibanisela yamaqabane ezinjalo kugcina iipropati zabo kwiqondo lobushushu ukuya ku 1316 ° C. izakhiwo data ofanelekileyo iikhompawundi kumphezulu ezithe rhoqo phantsi ubushushu, ngenxa yokuba ukusetyenziswa iwelding eqhelekileyo ngamanye amaxesha kunzima.

Imihlobo iwelding abandayo

Ukuba ufuna iglu "iwelding ngokucofa iqhosha lokulayita", ngoko ke kufuneka ubuze ukuba umenzi iinkonzo impahla emarikeni. iimveliso zasekhaya badla efikelelekayo ngakumbi, kodwa sibe kwizinga eliphezulu onjalo. Ngoko ke, iingcali bacebisa ukuba kunokwenzeka ukuba bafumane abavelisi amazwe yokwenza, kubandakanywa ABRO okanye Hi-Gear. Iimveliso kakuhle engqiniweyo abenzi zasekhaya, "Diamond" yaye "Polimet".

Ngokutsho ukwakhiwa iglu kunye guquki bayo zabo babefanele bahlule phakathi ulwelo kunye neentlobo ezifana ukutyabeka iwelding ezibandayo. Uhlobo lokuqala - i-component ezimbini imixube, ubunzima ekufuneka ugalelwe ngaphambi kokuba uyisebenzise. Kanye ngesamente ngembonakalo phantse yinto enzima ngodongwe eziqhelekileyo. Zibonakala njenge bar enye okanye ezimbini. Kwimeko yokugqibela, ubunzima kwi mixed ngaphambi kokuba uyisebenzise.

Sekunjalo athotyiweyo kwenzeka glue "iwelding lokulayita" jikelele, oko yenzelwe metal, ukulungiswa kwemoto kunye nokudibanisa iintsimbi kwamanzi. Uhlobo lokuqala ingasetyenziswa asebenze otyhidiweyo, iinkuni kunye ipholima. Ezi zinto ke eside kakhulu. Ukuba uthenga umxube otyhidiweyo, kuya kuba umxholo metal ibe ukumelana ngokugqibeleleyo nge welding of ezininzi zesinyithi.

Ukuba kufuneka asebenze phantsi kweemeko ezinzima, kuyimfuneko ukuba ukhethe kuqamba efanelekileyo, umz ololo osetyenziswa ukuwelda phantsi kwamanzi. Isigqibo sokwahlulwa lobushushu apho umthungo uyakwazi ukugcina amandla ayo nayo ibalulekile. I eliphezulu lobushushu eliphezulu, ukwakhiwa ezomeleleyo phantsi kwazo zonke iimeko zokusebenza.

Inkcazelo neepropati epoxy

Kwimarike kuhlangatyezwane nazo kwaye le ngcina epoxy-udongwe "welding lokulayita". Isetyenziswa ukuba kutywinwe iintanda zesinyithi aluminium zabo. A-Icandelo ezimbini ukwakheka kwaye kwe arhente enganyangekiyo ukuba epoxy nentlaka. Ukubunjwa iyamelana ukufuma, izinyibilikisi kunye neeoyile, yaye akukho iimpawu zotshintsho kunye nexesha.

iimveliso yesondo ingasetyenziswa kwiqondo lobushushu ezisukela -40 ukuya + 150 ° C. Ingqele welding "ngcina epoxy" nto nje, ugalelwe ngezandla, kwaye amacandelo sele ekhethiweyo idosi echanekileyo. Lom- emva kokufunyanwa lowo ukulungele ukuba ungasetyenziswa. Ugqitho lwe umxube igcinwe imizuzu emi-5, yaye emva ukuxuba ekwakhiweni linokusetyenziswa ukulungisa iinkcukacha sikhundla. Iyure iimveliso kamva unamathela unako ngomshini, ezizezi ziyakazele, ukugaya kusombiwa.

Inkcazelo neempawu iwelding lokulayita "Diamond"

welding enamathelayo lokulayita "Diamond" ayiphilise ingaphelanga iyure enye emva kokuba isicelo. Amandla sokugqibela salo mxube ufikelela ngosuku, ngoko ke imveliso ukuze phantsi loadings zezakhiwo. Ukuze usebenzise iglu eseleyo nsinya bhanyabhanya zipakishwe kwityhubhu.

Ukusebenza kunye nomxube kunokuba nkqu kwimeko apho iindawo nisondelelane abe isiqulatho esiphezulu sokufuma. Kulo mzekelo, ukwakhiwa kufuneka zibe mpuluswa ude uzive unamathela kumphezulu. Ngaphambi kokuba ayiphilise iglu kufuneka kwenziwa eliphelele imizuzu engama-20. Ukuba kuyimfuneko, ukukhawulezisa inkqubo ukunyanga ubume lisenziwa shushu ngako, ungasebenzisa dryer indlu. Umsebenzi kufuneka kwenziwe igumbi linomoya owaneleyo, inkosi kufuneka banxibe iiglavu. Njengenxalenye ingcina iqulethe:

• emahlamvini epoxy;
• fillers kwezimbiwa;
• hardeners;
• excipients zentsimbi.

Nihlinza amandla yi 120 kgf / cm², kanti lobushushu ngokwaphulwa yi 150 ° C. Brinell yobulukhuni yi 120 kgf / cm². Ubugcisa ukhusela umxube imizuzu eli-10, okuyinene kwiqondo lobushushu ezisukela-20 ukuya kwi-30 ° C. Lo msebenzi kufuneka wenziwe kwiqondo lobushushu ngezantsi + 5 ° C.

Cold iwelding ilinoliyam

Iglu "welding lokulayita" ilinoliyam afumaneka ezithengiswayo iintlobo ezintathu:

• Ngcina of uhlobo A;
• Ngcina lohlobo C;
• T. uhlobo ngcina

Le yokugqibela kusetyenziswa kungeyonto ayenza rhoqo. Ngcina of uhlobo A guquki ulwelo, njengoko kakhulu umxholo kuphela. isakhiwo enjalo yenza ukunyibilikisa ngempumelelo le ngcina buthelezi. umsantsa omkhulu ukugcwalisa ayikwazi le zithako, kuba kakhulu ulwelo.

Uncedo engundoqo Ukuphandwa ngokufumaneka beentanda zichanekile yaye phantse imperceptible. Clay ebandayo welding-uhlobo kakhulu impumelelo ilinoliyam elitsha. Ukuba yokusika ukusokola ekhaya, le webs edge koloko okungahambi kakuhle. Kulo mzekelo, kungcono ukuba athenge ingcina-uhlobo S.

Inkcazelo neempawu le ngcina uhlobo C

Njengenxalenye yale iglu ngaphezulu PVC kunye ngaphantsi kuphela. Umxube a abazizityebi elingqingqwa, ukuze ukwazi ukuyisebenzisa ngayo ukugcwalisa nkqu izikhewu ezinkulu neentanda. Loo mxube kokufanelekileyo ukuba kutywinwe iintanda ilinoliyam endala. Xa usebenzisa lo mxube, akukho mfuneko yokuba ukunyenyisa emiphethweni, izithuba avumeleke kuzo ukuya ku-4 mm. Emva yokomisa yenza umthungo owomeleleyo icocekile, qaphela ukuba kuya kuba nzima.

Inkcazelo glue ngenxa iwelding abandayo T

Oku kwakuse - kuba iwelding abandayo ilinoliyam, nesetyenziswa enqabile. kuqamba ezifanelekileyo ilinoliyam iikhompawundi multicomponent ngokusekelwe PVC kunye ipholiyesta. Ukusebenzisa olu hlobo iwelding ivumela ukuphumeza umthungo enokuthenjwa, oluchanekileyo kunye neemeko ngeemeko. Ifanele ukuba isakhiwo lib, nokuba semi-ezorhwebo ilinoliyam.

Iimpawu esisetyenziswe metal iwelding ebandayo "Thermo"

Iglu ngasentla - ebandayo iwelding metal, oko sisincoko metallosilicate awandisiweyo viscosity. Ifomula inika umxube ngokupheliswa ngu amaqokobhe uhlobo iziphene, neentanda kunye neetships. Sebenzisa le ngcina kumalungu metal ingenziwa elingqukuva intsimbi, intsimbi, titanium kunye nezinye aluminiyamu ubushushu ezingatshiyo.

Umxube ngempumelelo lokulungiswa ngamaqhekeza elinyukayo umlomo neentanda ngaphandle disassembly. Emva omiswe, omhlophe uba amandla aphezulu kunye nokumelana amanzi, ivavanywa a ukungcangcazela kunye ntshikilelo ngoomatshini. Iinxalenye ingasetyenziswa kwiqondo lobushushu ezisukela -60 ukuya +900 ° C.

Ngaphambi kokuba usebenzise le nxalenye kwakulungiswa kufuneka zihlanjwe isikali, mhlwa kunye nobunye ubumdaka, degreased kunye nesiseko acetone okanye nayiphi na enye ezimbaxa efanayo, ukususa imizila zeoli. Ukubunjwa kufuneka agalelwe de guquki efanayo, uze emva koko isicelo kumphezulu ngokulinganayo nge spatula.

isiphelo

Njengoko omnye iingenelo eziphambili iwelding abandayo okhonza akukho mfuneko yokuba uqeqesho olukhethekileyo. Master kufanele babe nezakhono ukuze kuzuzwe iziphumo ezidibanisayo iya kuba yanele nje ukuba ulandele imiyalelo apha.
