Upende ukushisa ukumelana for izoso: indlela engcono ukukhetha?

Uma uke wenza Yengcweti Yethusi noma walithenga esitolo ke manje noma ngokuhamba kwesikhathi, ngaphambi ukukhulisa umbuzo onjani upende ukuvikela ekhethiwe. Uma isakhiwo steel siqhutshwa emgwaqeni, kuyothiwa Njalo sibhekana umlilo imihlola emkhathini. Uma ungenalo ukuvikela ebusweni, ngokushesha nokugqwala.

izidingo Ukwakheka

Upende kumelwe ahlangabezane nezimfuneko ezithile, ivikela isakhiwo lapho ngaphansi lokushisa ezihlukile, umswakama kanye contact nge kwezulu. Kubalulekile ukuthenga upende, okuzodingeka njengoba umlilo, futhi ngeke zigcwale amanzi lapho zihlatshwa ilangabi. Phakathi kwezinye izinto, ukwakheka akufanele ukukhulula izinto eziyingozi, okuphathelene esigabeni isicelo kanye nokusebenza. ingxube Resistant uyakwazi withstanding okushisa afinyelela ku-800 °. Isicelo kuqonde, upende olunjalo ngokuvamile ingozi yezempilo, zingase ngesineke hhayi kuphela ngaphandle kodwa futhi Ingaphakathi umkhiqizo.

Okunhlobonhlobo upende ukushisa ukumelana

Penda ngokuba izoso lingasho omunye izinhlobo eziningana. Ukuvakashela esitolo, uzothola koqweqwe lwawo ezinengilazi, okuyinto imakethwa ngaphansi mshini KO KO 8101 noma 8111. Ukudayiswa kungabonwa ukushisa ukumelana upende brand KO / 08 nama-CA / 815, kanye nengoma organosilicate, phakathi yokugcina, ungakhetha OS 12/03. Isixazululo ethandwa kakhulu ngenxa lomnotfo lacquer ukushisa ukumelana KO-85. Kodwa liyazinikeza yayinesithiyo esisodwa, okuyinto sivezwe kula nesenzakalo kungenzeka imifantu lapho zihlatshwa okushisa aphansi. Ungakhetha futhi impregnation nemithi, njengengxenye equkethe kahle uwoyela ahlukahlukene nge nokuncipha lokushisa. Nokho, kufanele uzilungiselele ukuqinisekisa ukuthi impregnation enjalo sihlinzekela isidingo izibuyekezo zesikhathi. Uma uzobe ekhethelwe izoso upende, omunye eye kuchaziwe ngenhla, ngeke bakwazi ukumelana okushisa afinyelela ku-500 °. Ngu Ukwakheka ezinjalo, ingxube saka nomswakama eliphezulu futhi ukuvikela metal ukuba agqekeze.

upende acrylic

ukushisa Acrylic upende ukumelana for ukosa inyama zithandwa kakhulu ngenxa yokuthi ulungele ukuba ibhekane ithempelesha 650 ° C. Ngakho, lapho usebenza kusendlalelo kungathinta kafushane ithempelesha 800 ° C. Kuleli qembu kwempahla ehola aerosol amathini, inzuzo enkulu zazo ubhekwa omiswe okusheshayo. Kubalulekile ukukhumbula ukuthi upende ezinjalo kufanele ligcinwe ngaso izimo umenzi sika Kunconywa, kungenjalo kungase kube yisikhathi eside ngokwanele ukuze ome emva isicelo.

Uma uzosebenzisa upende acrylic for izoso, ngaphambi kokufaka isicelo ke akudingekile ukuba prime ebusweni, kodwa ungakhohlwa mayelana izindawo ukwelashwa ababe ezithandwa ukugqwala. Isendlalelo kwakhiwa ngeke lukhuthazelela umthelela nosawoti namafutha. Bheka ububanzi, ingakhethwa upende ukushisa ukumelana ngoba metal for izoso imibala ehlukene. Ethandwa kakhulu zazo yilezi: omnyama, ompunga, elinsundu, nesiliva.

Sibutsetelo izici ukushisa ukumelana powder upende

I powder enamathela izingoma ubuchwepheshe ezahlukene. upende Dry kufanele olufuthwe phezu kwaleyo, bese kuvezwa lokushisa eliphezulu. Ngesikhathi sintering iba ingxenye ukusebenza edingekayo, amandla ephezulu lokushisa phakathi lapho. Isibonelo kungaba S54 powder upende brand elenziwe ngesisekelo abicah. Lokhu Ukwakheka ngokukhethekile eyenzelwe Ukuvikelwa ebusweni amapuleti, ukosa inyama kanye grills ekhaya. Kodwa ekhaya ukusebenzisa kuyoba nzima, ngoba isidingo ukusebenzisa ephezulu lokushisa omiswe ekamelweni.

Ukwahlukanisa upende ukushisa ukumelana

Uma udinga upende ukuze izoso ke udinga ukuqonda ngezigaba yalezi ukwakhiwa. Basuke evamile ihlukaniswe izigaba, njenge: ensimini ukusetshenziswa, izinga lokushisa, ukubunjwa, nezinye izinto. Ngokwesibonelo, ukuze isetshenziswe ekhaya ukusebenzisa izingoma ukuthi zenzelwe ukusebenza ezingeni lokushisa ngaphakathi kobubanzi kusuka 80 kuya ku-100 ° C. Abakwazi akhiphe isahlulelo acrylic noma resin alkyd. Ngosizo lwabo, sebakwati ungqimba Monolithic zokuzivikela. Uma sikhuluma izimo lokushisa ezisukela 100 kuye ku-120 ° C, kungcono ukuba ukhethe upende esekelwe epoxy resin. Sales zingatholakala monocomponent upende okuyinto zenzelwe ukusebenza ezingeni lokushisa 200 kuya ku-400 ° C. izithako engeziwe equkethwe ether epoxy inhlaka ETHYL silicate. Ukuze uthole uhla lokushisa lapho ifinyelela 750 ° C, kungcono ukusebenzisa ingxube kule amasilinda njengoba izifutho. Ukuze izimo lapho izinga lokushisa likhuphuka ngenhla 700 ° C, kungcono ukusebenzisa Izingxube esekelwe resin abicah.

Ukuze uthole eminye imininingwane kophawu

Upende ukushisa ukumelana ngokuba izoso kumele kumakwe ngu okuyigama nezinombolo. Uma ubona izinhlamvu ezimbili "KO", lokho kubonisa ukuthi ngaphambi ukupenda esekelwe abicah isibopho. Ngemva izinhlamvu izinombolo, olokuqala okhombisa uya khona. Ngakho, imibukiso eziyisishiyagalombili nokushisa ukumelana. Eyesibili futhi zonke izibalo ngemva kwalokho kubonisa isibalo ukuthuthukiswa ikhathalogi. Ngaphambi kokuba uthenge kunconywa ngijwayele ukuqokwa kwabasebenzi. Ngakho, CO-811 isetshenziselwa aluminium, steel, titanium evele okuyinto kudingeka sivikelwe ukugqwala. Lezi enamels zinhle ukuthi avunyelwe isicelo sabo ngaphansi kwamazinga okushisa aphansi. Ngenxa yalokho, Ukusabalala ingatholakala okuyinto ehlukile emvelweni kwedivayisi, ukushisa kanye umswakama ukumelana nokuzabalazela yanjalo amalahle kanye eqeda. Lapho izinga lokushisa kwandisa, luthi alufane iba namandla nakakhulu izinga.

CO-813 - laqanjwa ukuthi isetshenziselwa Umdwebo zokuzivikela metal evele obala okushisa ku ekupha 60 kuya 500 ° C. Kuyaphawuleka ukuthi upende ukushisa ukumelana for izoso sinezici anticorrosive, ke akesabi abukhali umswakama high kanye lokushisa ekushintshashintsheni. Uma kudingekile ukuvikela ebusweni, okuyinto ngesikhathi operation babhekana lokushisa 400 ° C, bese ukhetha i-DA-814. I enamathela okuholela has a ukumelana usawoti izixazululo, amafutha amaminerali kanye amafutha amaminerali. Lokhu Ukwakheka ezindaweni ezihlukahlukene, njengoba ingasetshenziswa ukudaywa and umusi amapayipi nge umusi ashisayo. KO-8111 - le ngxube ngayo nefunda ngayo kungenziwa zaveza metal izakhiwo, eliwu 600 ° C. Kuyinto ukumelana ukugqwala.

Yini bakhetha - koqweqwe lwawo noma upende

Uma namanje abazange usunqumile ukuthi hlobo luni upende ukupenda hlupha, ungase uthande ukucabangela izinga enamels nopende. Ngemuva kokufaka isicelo opaque ifilimu wokuqala okuqinile kwakhiwa endaweni elikwaziyo ukuvikela kusuka umswakama high, kodwa hhayi ukuchayeka ukuvula amalangabi. Lapho eqhathanisa enamels ukushisa ukumelana nopende Kufanele kushiwo ukuthi yangaphambili ikhululekile, ube okusezingeni eliphezulu izakhiwo zokuhlobisa, dala enamathela okuhlala isikhathi eside, kodwa isicelo sabo kuvunyelwe ngisho noma kushisa sub-zero. Nokho, upende ukuze izoso (1000 degrees) is hhayi yavutha, uma lokho kuzokwenza kungithinte ilangabi, okuyinto akunjalo koqweqwe lwawo.

isiphetho

Penda ngoba metal ngokuba izoso kufanele kukhethwe futhi ngemkhiqizo. Ngokwesibonelo, "Termika" ukhiqiza compounds ezifanayo kusukela ngo-2007. Imikhiqizo umphakeli iye eqinisekisiwe, futhi izindleko cishe kuyoba ruble 142. kilogram per.

Ungase owakhethwa upende ukushisa ukumelana ngoba metal for izoso Dufa umkhiqizo, okuyinto ezibizayo -. Ruble 400, kodwa ikuvumela ngokushelela ukusabalalisa okushisa aphezulu we ebusweni ngesineke, ekuqedeni okweqile. Njengoba inzuzo ukungabikho koqweqwe lwawo ukhonza carbohydrate elimnandi, okuvumela ukusetshenziswa Ukwakheka ngaphakathi egumbini.
