Izici ze-YC-8102 High-Temperature Eval Anti-Oxidation Nano-Composite Ceramic Coating (Okuphuzi Okukhanyayo)

Incazelo emfushane:

I-Nano-coatings yimikhiqizo yokuxhumana phakathi kwe-nano-materials ne-coatings, futhi iwuhlobo lwezingubo ezisebenzayo zobuchwepheshe obuphezulu. Ama-nano-coatings abizwa ngokuthi ama-nano-coatings ngoba ubukhulu bezinhlayiyana zawo buwela ngaphakathi kwebanga le-nanometer. Uma kuqhathaniswa nezingubo ezijwayelekile, ama-nano-coatings anokuqina okuphezulu nokuqina, futhi anganikeza ukuvikeleka okuhlala isikhathi eside.

Uketshezi oluphuzi ngokuphaphathekile

I-substrate esebenzayo

Insimbi ye-carbon steel, insimbi engagqwali, insimbi eyinsimbi, i-aluminium alloy, i-titanium alloy, insimbi ye-alloy esezingeni eliphezulu, izitini ezivikelayo, imicu ye-insulating, ingilazi, izitsha zobumba, okusansimbi okunezinga lokushisa eliphezulu konke kungasetshenziswa endaweni engaphezulu kwamanye ama-alloys.

Izinga lokushisa elisebenzayo

Ukumelana okuphezulu kwezinga lokushisa ngu-1400 ℃, futhi imelana nokuguguleka okuqondile ngamalangabi noma ukugeleza kwegesi enezinga eliphezulu lokushisa.

Ukumelana nokushisa kwe-coating kuzohluka ngokufanele kuye ngokuthi ukumelana nokushisa kwama-substrates ahlukene. Imelana nokushaqeka okubandayo nokushisa nokudlidliza okushisayo.

Izici zomkhiqizo

1. I-Nano-coatings iyisici esisodwa, imvelo, ayinabo ubuthi, kulula ukuyisebenzisa futhi inokusebenza okuzinzile.

2. I-coating iminyene, i-anti-oxidation, i-asidi ne-alkali ukumelana, futhi imelana nokugqwala kwezinga eliphezulu lokushisa.

3. I-Nano-coatings inamandla amahle okungena. Ngokungena, ukumboza, ukugcwalisa, ukuvala nokubunjwa kwefilimu, ekugcineni bathola ukubekwa uphawu okuzinzile okunezinhlangothi ezintathu kanye ne-anti-oxidation.

4. Inokusebenza okuhle kokwenza ifilimu futhi ingakha ungqimba lwefilimu oluminyene.

5. I-coating imelana nokushisa okuphezulu kokushisa nokushisa ukushisa, inokumelana nokushaqeka okuhle kokushisa, futhi iye yabhekana nokuhlolwa kokupholisa kwamanzi izikhathi ezingaphezu kuka-20 (ukumelana nokubandayo nokushisa, ukumboza akuqhekeki noma kukhishwe).

6. Ukunamathela kwe-coating kukhulu kune-5 MPa.

7. Eminye imibala noma ezinye izakhiwo zingalungiswa ngokuvumelana nezidingo zamakhasimende.

Izinkambu zohlelo lokusebenza

1. Metal surface, ingilazi surface, Ceramic surface;

2. Ukuvalwa kwe-graphite surface kanye ne-anti-oxidation, ukubekwa uphawu kwendawo yokushisa ephezulu kanye nokunqanda ukugqwala;

3. Isikhunta se-graphite, izingxenye ze-graphite;

4. Izingxenye ze-boiler, izishintshi zokushisa, ama-radiator;

5. Izesekeli zesithando somlilo kagesi kanye nezingxenye zikagesi.

Indlela yokusebenzisa

1. Ukulungiselela upende: Ngemva kokunyakazisa noma ukunyakazisa kahle, ungasetshenziswa ngemva kokuhlungwa ngesikrini sokuhlunga esingu-300-mesh. Ukuhlanzwa kwesisekelo: Ngemuva kokunciphisa nokukhipha amafutha, kunconywa ukwenza i-sandblasting ukuze kuthuthukiswe umphumela ongaphezulu. Umphumela omuhle kakhulu we-sandblasting ufinyelelwa nge-46-mesh corundum (i-corundum emhlophe), futhi kuyadingeka ukuthi ufinyelele ebangeni le-Sa2.5 noma ngaphezulu. Amathuluzi okugcoba: Sebenzisa amathuluzi okugcoba ahlanzekile nawomile ukuze uqiniseke ukuthi awekho amanzi noma okunye ukungcola okunamathela kukho, ukuze ungaphazamisi umphumela wokumboza noma ubangele imikhiqizo enesici.

2. Indlela yokumboza: Ukufafaza: Fafaza endaweni yokushisa yasekamelweni. Kunconywa ukulawula ukushuba kokufafaza ngaphakathi kwama-microns angama-50 kuye kwayi-100. Ngaphambi kokufafaza, i-workpiece ngemuva kwe-sandblasting kufanele ihlanzwe nge-ethanol anhydrous futhi yomiswe ngomoya ocindezelwe. Uma ukuwohloka noma ukuncipha kwenzeka, isiqeshana sokusebenza singashiswa kuze kufike ku-40 ℃ ngaphambi kokufutha.

3. Amathuluzi Wokumboza: Sebenzisa isibhamu sesifutho esinobubanzi obungu-1.0. Isibhamu sesifutho esinobubanzi obuncane sinomphumela ongcono we-atomization kanye nomphumela ongcono kakhulu wokufafaza. I-compressor yomoya kanye nesihlungi somoya kufanele kufakwe.

4. Ukwelapha kokumboza: Ngemva kokuphothulwa kokufafaza, vumela ucezu lokusebenzela lome ngokwemvelo cishe imizuzu engama-30, bese ulufaka kuhhavini bese ulugcina ku-280 degrees imizuzu engu-30. Ngemuva kokupholisa, ingakhishwa ukuze isetshenziswe.

Ihlukile ku-Youcai

1. Ukuzinza kwezobuchwepheshe

Ngemuva kokuhlolwa okunzima, inqubo yobuchwepheshe be-aerospace-grade nanocomposite ceramic ihlala izinzile ngaphansi kwezimo ezimbi kakhulu, imelana nokushisa okuphezulu, ukushaqeka okushisayo nokugqwala kwamakhemikhali.

2. Ubuchwepheshe be-Nano-dispersion

Inqubo eyingqayizivele yokuhlakazeka iqinisekisa ukuthi ama-nanoparticles asatshalaliswa ngokulinganayo ekuhlanganiseni, ukugwema ukuhlangana. Ukwelashwa kwesixhumi esibonakalayo okusebenzayo kuthuthukisa ukuhlangana phakathi kwezinhlayiya, kuthuthukise amandla okubopha phakathi kokumboza ne-substrate kanye nokusebenza kukonke.

3. Ukulawulwa kokugqoka

Ukwakheka okunembile nezindlela eziyinhlanganisela zenza ukusebenza kwe-coating kukwazi ukulungiseka, njengokuqina, ukumelana nokugqokwa kanye nokuzinza kokushisa, okuhlangabezana nezidingo zezinhlelo zokusebenza ezahlukene.

4. Izici zesakhiwo se-Micro-nano:

Izinhlayiya ze-nanocomposite ze-ceramic zigoqa izinhlayiya ezincane, zigcwalise izikhala, zenze uqweqwe oluminyene, futhi zithuthukise ukubumbana nokumelana nokugqwala. Phakathi naleso sikhathi, ama-nanoparticles angena ebusweni be-substrate, enza i-metal-ceramic interphase, ethuthukisa amandla okubopha kanye namandla onke.

Umgomo wocwaningo nentuthuko

1. Inkinga yokuqhathanisa yokwandisa okushisayo: Ama-coefficients wokunweba okushisayo wensimbi nezinto zobumba ngokuvamile ahluka phakathi nezinqubo zokushisisa nokupholisa. Lokhu kungase kuholele ekwakhekeni kwama-microcracks enamathela ngesikhathi senqubo yokushisa kwamabhayisikili, noma ngisho nokuxebuka. Ukuze kuxazululwe le nkinga, i-Youcai ithuthukise izinto zokugqoka ezintsha ezine-coefficient of thermal extension eduze ne-substrate yensimbi, ngaleyo ndlela inciphisa ukucindezeleka okushisayo.

2. Ukumelana nokushaqeka okushisayo nokudlidliza kwe-thermal: Lapho i-metal surface coating ishintsha ngokushesha phakathi kwamazinga okushisa aphezulu naphansi, kufanele ikwazi ukumelana nokucindezeleka okushisayo okubangelwayo ngaphandle kokulimala. Lokhu kudinga ukunamathela ukuze kube nokumelana nokushaqeka okuhle kakhulu kwe-thermal. Ngokulungiselela i-microstructure ye-coating, njengokwandisa inani lezindawo zokusebenzelana kwesigaba nokunciphisa usayizi wokusanhlamvu, i-Youcai ingathuthukisa ukumelana kwayo nokushaqeka okushisayo.

3. Amandla okubopha: Amandla okubopha phakathi kokumboza kanye ne-substrate yensimbi ibalulekile ekuzinzeni kwesikhathi eside nokuqina kwentolo. Ukuze kuthuthukiswe amandla okubopha, i-Youcai yethula isendlalelo esiphakathi nendawo noma isendlalelo soguquko phakathi kokumboza ne-substrate ukuze kuthuthukiswe ukumanzi nokuhlangana kwamakhemikhali phakathi kwakho kokubili.
