Upende Heat nemithi, metal: izinhlobo nobukhulu

imikhiqizo Resistant upende senzelwe metal ukwelashwa surface, Usebenzela ukuvikela izakhiwo ahlukahlukene emiphumeleni elimazayo ukugqwala kubangelwa amakhemikhali weathering ezenzeka ngaphansi kwezimo yokusebenza ngesikhathi ephakeme okushisa kuma. Uma izindonga zipendwe ngopende ezivamile amaziko ezimbonini kanye amapayipi, yasendlini kurediyetha noma yimuphi omunye amadivaysi, ngaphansi kwethonya amalahle ukuwa enamathela ungqimba ngemuva ebusweni, kanye metal ayeyochayeka. Kungaphindze kube netikhatsi kancane elimazayo kuya nensimbi, kodwa ezingemnandi kusukela iphuzu yobuhle buka, lo mkhuba - yellowing we upende.

Okwamanje, umkhakha chemical ukhiqiza izinhlobo eziningana uyinki ukushisa ukumelana eyenzelwe yokudweba metal evele, kuye ngokuthi lokushisa imvelo lapho uzobe eziqhutshwa elilodwa noma omunye umkhiqizo.

Lesi sangoma lapho ebusweni metal uyabaselwa lokushisa 80 ° C, evumela ukusetshenziswa kwanoma yimuphi umsebenzi upende.

I ukushisa ukumelana upende ngoba metal, lenziwa okusekelwe alkyd futhi acrylic inhlaka, esetshenziselwa ukudaya izakhiwo wadalula okushisa afinyelela ku-100 ° C, iqukethe izithasiselo ekhethekile ukushisa ukumelana, okuyinto ukuvimbela ebusweni yellowing lapho sishiswa ngakho. Ngokuvamile, lolu hlobo isetshenziselwa staining ka radiators yasendlini namanzi ashisayo ompompi.

Ukuze staining etindlela ehlukahlukene timphawu tesakhiwo ezisebenza at okushisa afinyelela ku-120 ° C usebenzisa upende ukushisa ukumelana ngoba metal, wenza usebenzisa i primer epoxy kanye ne ukwengeza zinc ne-zinc-phosphate izingxenye. Epoxy Enamel ingaphinda isetshenziswe at okushisa ephakeme - 200 ° C.

Lapho umbuso lokushisa kuze kufinyelele 400 ° C Kunconywa ukuba asebenzise enamathela eyodwa ingxenye, umongo equkethe ETHYL silicate futhi epoksiefirnye resin. Ngalesi lokushisa, zombala ezivamile nokutubeka kwenzeka ngaso leso sikhathi, ngakho-ke lokhu upende ukushisa ukumelana iqukethe zensimbi ngezithako zawo powder metal. Lokhu ukushintshashintsha singasebenza isihloko e isendlalelo esisodwa.

Ezimweni yokusebenza, umkhiqizo noma isakhiwo endaweni lokushisa isukela kuze ku 650ºC, ochwepheshe batusa ukusebenzisa isakhi enamathela olulodwa, umongo equkethe abicah resin. Kulokhu, upende ukushisa ukumelana is isetshenziswa ebusweni metal ungqimba mncane kakhulu kokuba ukubaluleka kusukela microns 30 kuya ku-100.

Umbuso lokushisa okweqa 650ºC kuhilela ukusetshenziswa njengendlela enamathela Umbala impahla ekhiqizwa ngesisekelo ukushisa-resistant glass kanye izinto oluyinhlanganisela.

Coating yama-materials Umbala imikhiqizo metallic ehilelekile nemibandela lokushisa eliphezulu, kufanele okusezingeni eliphezulu nemihuzuko nawo, zinamandla futhi nezimo, ephephile imvelo, ezimi njalo. Abakwazi ozofakwa ebusweni njengoba egumbini avaliwe, futhi ngaphandle. I yokuntula kokusebenzisa inki ukushisa ukumelana zihlanganisa indlela yokusebenzisa - idatha upende, isibonelo epoxy upende , metal, isetshenziswa ebusweni by sishaye, futhi lokhu kuhilelani anda ukusetshenziswa impahla.
