Tshuaj tsuag thermal yog dab tsi?

Kev txau thermal yog ib txoj kev txheej txheem uas txau cov khoom siv cua sov rau ntawm ib qho chaw kom npog nws thiab ua rau nws tsis yooj yim rau kev puas tsuaj, kev xeb, kev yaig, kev sib txhuam lossis cavitation. Ntau yam khoom siv tuaj yeem siv rau hauv kev txau thermal, tab sis peb yam khoom siv feem ntau yog hlau, ceramics thiab plastics. Cov khoom siv (lossis cov khoom noj khoom haus) raug cua sov los ntawm hluav taws xob (plasma lossis arc) lossis tshuaj lom neeg (hluav taws kub hnyiab) kom ua ib qho dej ntws ntawm cov khoom me me uas faib ua feem ntau hauv lub xeev molten lossis semi-molten cuam tshuam rau ntawm lub substrate los tsim ib txheej. Cov khoom noj khoom haus tuaj yeem yog cov pas nrig, hlau, hmoov lossis kua.

Feem ntau cov tshuaj tsuag thermal yog siv los tiv thaiv lossis kho cov khoom siv saum npoo. Ib qho txiaj ntsig ntawm cov tshuaj tsuag thermal yog tias nws txheej cov khoom siv saum npoo nrog ib daim ntaub thaiv kev tiv thaiv. Piv txwv li, ib qho chaw uas muaj hlau khov kho yuav tiv taus kev hnav, kub, thiab kev sib txhuam. Lwm qhov txiaj ntsig yog tias cov tshuaj tsuag thermal tuaj yeem kho cov khoom siv saum npoo. Ib qho khoom siv uas puas lawm lossis xeb tuaj yeem txau nrog cov tshuaj pleev xim kom rov qab zoo li qub. Txawm hais tias cov tshuaj tsuag thermal tsis ntxiv zog rau cov khoom siv, nws yog ib txoj hauv kev ceev thiab pheej yig los kho qhov loj ntawm cov khoom siv. Cov haujlwm sib tsoo tom qab ntawd feem ntau xav tau los ua kom cov xim pleev xim du thiab coj qhov loj kawg mus rau lawv qhov kev kam rau siab.Cov siv tawv xuab zeb diamondyog siv dav rau kev ua haujlwm sib tsoo.

Cov txiaj ntsig tseem ceeb thiab cov yam ntxwv ntawm thermal spray ua ib txheej txheem txheej txheem tau muab tso ua ke hauv qab no:

● Nws tsis xav tau cov tshuaj volatile organic (VOCs) uas ua rau tib neeg thiab ib puag ncig puas tsuaj.
● Muaj ntau yam khoom siv siv tau ua cov khoom noj khoom haus: hlau, alloys, ceramics, cermets, carbides, polymers thiab plastics.
● Cov txheej txheem txau thermal raug sib txuas nrog lub substrate. Cov khoom siv txau uas tsis sib haum nrog lub substrate los ntawm kev siv hlau.
● Muaj peev xwm tsuag cov khoom siv txheej uas muaj qhov kub siab dua li cov substrate.
● Cov tshuaj tsuag thermal yuav siv tau ob qho tib si manually thiab machined.
● Cov txheej txheej tuab tuaj yeem siv tau rau qhov siab ntawm kev tso dej.
● Feem ntau cov khoom siv tau txau nrog me ntsis lossis tsis muaj kev kho ua ntej lossis tom qab cua sov, thiab qhov kev cuam tshuam ntawm cov khoom yog qhov tsawg heev.
● Cov khoom seem tuaj yeem rov tsim dua sai thiab pheej yig, thiab feem ntau pheej yig dua li tus nqi hloov pauv.
● Los ntawm kev siv cov khoom zoo tshaj plaws rau cov txheej txheem thermal spray, lub neej ntawm cov khoom tshiab tuaj yeem ntev dua.

Muaj ntau hom txheej txheem txau thermal. Lawv txawv ntawm lawv siv lub zog thermal thiab kinetic rau cov khoom siv, daim ntawv ntawm cov khoom siv thiab qhov ceev thiab kub ntawm nplaim taws. Txhua txoj kev muaj qhov zoo thiab qhov tsis zoo, thiab qee qhov tau ua kom zoo rau qee hom txheej txheem.
Cov txheej txheem tshuaj tsuag thermal tau siv dav dav rau ntau xyoo thoob plaws txhua qhov kev lag luam engineering loj suav nrog kev tsim cov roj turbines, diesel cav, bearings, journals, twj tso kua mis, compressors thiab cov khoom siv roj av, nrog rau kev pleev xim rau cov khoom siv kho mob. Cov khoom siv thiab kev txhim kho cov txheej txheem tsis ntev los no tau txhim kho qhov zoo thiab nthuav dav ntau yam kev siv rau cov tshuaj tsuag thermal.
