Kuyini enamathela polymer? I polymeric enamathela metal

I polymer enamathela - ithuba eliyingqayizivele ukuvikela metal evele. Lena indlela ephumelela kakhulu futhi yesimanje ukuze silwe ukugqwala, okuzokwenza asavela ngokushesha noma kamuva imikhiqizo metal.

Kuyini?

Ukuze uthuthukise properties ukusebenza insimbi esetshenziswa polymers ukuthi kungaba asabela ngaphansi kwezimo ezithile. ezinengilazi ezinjalo izingoma ezomile esekelwe ukuhlakazwa enhle powder, okuyinto eminye wanezela hardeners, fillers futhi eba nezakhi zombala ezenza. I enamathela polymer wakhethwa ukwandisa safeners metal akukho izinsimbi ingozi ukuqhuba zamanje kagesi, futhi ngenxa yalokho, icala idluliselwe isihloko, kanjalo ukwakha inkambu electrostatic. Lidonsa izinhlayiya powder, ukuzigcina phezu workpiece. I engavamile we enamathela polymer - ngezinga eliphezulu wokumelana yimuphi hlobo lwempendulo. Ngaphezu kwalokho, kuyinto aesthetically elimnandi.

Njengoba polymerization senzeka

Thenga powder enamathela sinetigaba eziningana:

• Imigomo ukulungiselela umkhiqizo: luthi alufane polymeric lasetshenziswa kahle futhi nombala, umkhiqizo sensimbi kuqala kahle bahlanza kusuka uthuli, nokugqwala, udoti. Kungcono ukusebenzisa ngempumelelo sandblasting ne phosphate. Isinyathelo okugunyaziwe - degreasing ebusweni metal.
• sebethule chamber: e Umdwebo spray idokodo wenziwa ngqo. Thermal chamber, Lungafinyelela okushisa 200 degrees futhi okungukuthi sekuqala ukufudumala ngokulinganayo. I powder iqala igcwale amanzi, kanjalo zakha isimiso enamathela flat futhi smooth phezu bonke ubuso insimbi ikhule ezimbotsheni angaphakathi ayogcwaliswa.
• Umkhiqizo polymerization wenziwa ekamelweni ukupholisa: izinga lokushisa is kancane kancane ewa, kanye ifilimu polymer kuba nzima. Ngemva kwamahora angu-24, luthi alufane polymer ilungele ukusetshenziswa.

ubuchwepheshe umbala: essence

Powder enamathela wenziwa izigaba eziningana. Uma uyikha phezulu le phansi icutshungulwe. KubaluleKile ukuthi metal imikhiqizo kahle bahlanza of ukungcola, oxides, futhi degrease ebusweni kuyothuthuka adhesion. Ngemva ukulungiselela, isinyathelo esingalindelekile, ofihla izici imikhiqizo sensimbi, okuyinto akufanele ufake Ukwakheka powder.

Imininingwane kufanele kusetshenzwe, hang ohlelweni zokuhamba, bese wathumela ku Umdwebo ekamelweni. Ngemva sishaye phezu ungqimba powder metal Kumiswa. In the isinyathelo polymerization yakha enamathela okuyinto ungqimba Fusion inki.

Yiziphi izici?

Metal polymer iphathwa enamathela, libhekene nokwethenjelwa ukuqina okusezingeni eliphezulu. Isizathu siwukuthi kwakhiwa uphawu ifilimu Monolithic esehlanganise ngokuphelele ebusweni sihloko futhi ngokuqinile elikulo. Ngenxa polymer enamathela metal has:

• adhesion okusezingeni eliphezulu kwamanzi;
• amandla okusezingeni eliphezulu futhi ihlala isikhathi eside;
• ukuphila isikhathi eside ebe egcina impahla uqobo;
• ububanzi ezahlukene imibala;
• umjikelezo zokukhiqiza okusheshayo.

enamathela metal Polymeric wenziwa esekelwe ngezinto ezahlukene kanye Umbala izimpushana. Indaba ethile kuncike inhloso enamathela sisetshenziswa njengoba izakhiwo zokuhlobisa ibalulekile.

polyester

Polyester ngokuvamile esetshenziselwa polymer enamathela metal. Lena impahla engabizi ukuthi has ezingeni lelisetulu eguquguqukayo, moldability, ngaphezu kwalokho, ingasetshenziswa kuzo zonke sezulu. Ishidi polymer esekelwe polyester enamathela linamandla yelanga futhi ukugqwala ukuba. Material yakha high ifilimu, eliqinile phezu, lapho izimo zokuthwalwa amanye amashidi steel zilethwa njengoba yayinjalo.

Kabanzi futhi matte polyester: luthi alufane has a ukushuba encane kakhulu, kanye ebusweni metal uphendulela matt. I engavamile we indaba - a high umbala fastness, ukumelana enhle ukugqwala futhi ukucindezeleka mechanical.

plastisol

Omunye ethandwa polymeric enamathela metal - plastisol. Njengengxenye yalolu impahla zokuhlobisa - PVC, plasticizers; Ngaphandle, ikhanga ebusweni embossed. Lona enamathela eqolo, futhi ngesikhathi esifanayo ukumelana kakhulu umonakalo mechanical ngenxa okusezingeni eliphezulu enamathela ukujiya. Ngakolunye uhlangothi, indaba akanayo okusezingeni eliphezulu lokushisa ukumelana, futhi ngenxa yalokho elangeni ngesikhathi okusezingeni eliphezulu lokushisa enamathela ngeke ukuwohloka. Ngenxa ukushuba elikhulu ukumelana ukugqwala eliphezulu plastisol.

steel Okudumile polymer enamathela esekelwe Puranas, okuyinto kuyahluka silky-matt isakhiwo ebusweni. Ukumelana lokushisa namakhemikhali ejenti kwenza ukwakheka nezidumile ngensimbi.

Izimpawu steel camera

Properties of izinto camera - ngezikhwepha, formability, okusezingeni eliphezulu ukugqwala ukumelana. Emva ekucubunguleni steel iba ukubukeka esihle, okungase bayicabange imibala kanye shades. Qasha ezenziwe ngokuvumelana GOST, polymeric enamathela izinga eyatholakala. rolling Painted kungenzeka olulodwa noma kabili enamathela ezahlukeneyo zingenzeka lapho izidakamizwa sisetshenziswa kulowo noma zombili. Ngenxa ngcono izakhiwo polymer enamathela ukusebenza yilezi:

• polymer camera metal zingahlungwa zibe imikhiqizo eseqedile;
• lokunameka nombala basakaza phezu kwamanzi, degree ke umfaniswano Ukuvikelwa;
• ke siwulimi ukungabi isiqinisekiso amazinga ezinhle Ukuvikelwa;
• steel has adhesion ezinhle;
• metal ungagcina izakhiwo zokuzivikela futhi zokuhlobisa ngoba eyi-10.

Kusukela kwezomnotho ngokombono steel lashukumisa camera kunenzuzo ngaphezulu: okokuqala, kunomthelela umkhiqizo okusezingeni eliphezulu nekhwalithi, kusukela kwehlisa enamathela izindleko. Okwesibili, umthengi ayidingi ukutshala ekucubungululeni ezengeziwe of okuhlinza ukuvikela ubuso bayo. Qaphela ukuthi ukumelana ukugqwala of okuhlinza lashukumisa, okuyinto kusetshenzwe ngumuntu enamathela polymer incike ukujiya ungqimba. Ukuze kwandiswe ngokuphila service imikhiqizo steel, basuke ngaphezu kwalokho embozwe ezimbili zamatshe polymer, okwenza lokuvikeleka kwezifiso ezisemqoka ezingumphumela metal ephakeme.

Ukusabalala Izici

enamathela Polymeric - ifilimu esesikhundleni lonke iqoqo ukusebenza azifani. rolling Prestained kudalwa esekelwe izinhlobo eziningana polymers. Noma iyiphi impahla selashwe le ndlela - noma anezikhala steel ishidi camera - ezahlukene umthelela ukumelana, ukumelana ukugqwala imiphumela adhesion okusezingeni eliphezulu. Kubalulekile futhi ukuthi lo powder Umdwebo ikuvumela ukuba wenze zensimbi ebusweni ngokuya umbala, kufaka phakathi i-eyayenziwe osemdala, isibonelo, ngaphansi Antique isitayela.

Namuhla inqubo ethandwa olungele ukudaya steel iphuma njengoba Ikhoyili esinemthombo. Ingqikithi indlela ukuthi enamathela sisetshenziswa kumugqa ezenzakalelayo, isb coiled amashidi iphuma kusetshenzwe emgqeni, okwathi ngemva kwalokho babuyela umshini Valikova camera. Lobu buchwepheshe sandile ngenxa yokuthi akukho ukulahleka impahla, kanye umugqa ngokwawo iyashelela futhi ke inzuzo.

Njenganoma iyiphi eminye imisebenzi kokuqeda, kuyadingeka ukulungiselela ebusweni kuqala, khona-ke imibala. Lokhu ubuchwepheshe ivumela eliphezulu ukucutshungulwa steel, i-aluminiyamu nezinye tinplate. Ngakho, luthi alufane polymer - kungenzeka ukuthuthukisa ukusebenza kwe-metal, ngcono izakhiwo zalo begodu isikhathi wokusebenza.
