Cov yas thiab hlau puas tuaj yeem welded ua ke? Koj puas xav tau cov cuab yeej siv vuam tshwj xeeb?

Hauv kev tsim khoom thiab tsim cov khoom siv niaj hnub, kev sib xyaw ntawm cov yas thiab hlau yog ntau heev, xws li cov khoom siv sab hauv tsheb thiab cov khoom siv hluav taws xob. Txawm li cas los xij, ob cov ntaub ntawv muaj cov khoom sib txawv heev, thiab ntau tus neeg xav tsis thoob: Cov yas thiab hlau puas tuaj yeem welded ua ke? Yog tias ua tau, cov khoom siv vuam tshwj xeeb puas xav tau?

 I. Yas thiab Hlau: Cov vuam siv tau zoo, tab sis cov khoom sib txawv yuav tsum tau kov yeej

Plastics yog siab - molecular - hnyav cov ntaub ntawv uas muaj cov ntsiab lus melting tsawg (feem ntau yog nyob nruab nrab ntawm 100 - 300 ℃) thiab nws nquag deformation thaum rhuab. Cov hlau, ntawm qhov tod tes, muaj cov ntsiab lus melting siab (cov hlau feem ntau yaj ntawm tshaj 1000 ℃) thiab siab thermal conductivity. Cov txheej txheem vuam tsoos (xws li arc vuam thiab cov thermal melting vuam zoo tib yam) tsis tuaj yeem tsim kev sib txuas ruaj khov ntawm ob. Txawm li cas los xij, nws muaj peev xwm ua tau tag nrho rau vuam yas thiab hlau los ntawm cov txheej txheem tsom. Qhov tseem ceeb nyob rau hauv kev daws ob qhov teeb meem loj: 'mismatched thermal teb ntawm ob cov ntaub ntawv' thiab 'tsis muaj zog interfacial bonding.'

Tam sim no muaj ob txoj hauv kev ua tau zoo. Thawj yog 'thermal melting + interface activation.' Los ntawm cua sov cov yas kom txog thaum nws melts thiab ces qhwv nws nyob ib ncig ntawm cov hlau nto, thiab pre-kho cov hlau nto (xws li sib tsoo los yog siv ib tug coupling agent), adhesion ntawm cov yas thiab hlau yuav txhim khu kev qha. Qhov thib ob yog 'zog - tsom welding.' Txoj kev no siv cov khoom siv hluav taws xob xws li ultrasound lossis lasers hauv zos tsim kom muaj qhov kub thiab txias ntawm qhov sib txuas ntawm cov yas thiab hlau. Qhov no tso cai rau cov yas kom yaj sai sai thiab sib raug zoo nrog cov hlau yam tsis muaj cua sov rau cov hlau. Piv txwv li, nyob rau hauv kev tsim cov tsheb sensors, ultrasonic vuam tau ruaj khov txuas yas casings nrog hlau pins, ua tau raws li qhov yuav tsum tau rau sealing thiab hluav taws xob conductivity.

 II. Cov cuab yeej siv vuam tshwj xeeb yog qhov tseem ceeb: Cov cuab yeej siv tsis tuaj yeem ua tau raws li qhov xav tau ntawm Hla - Cov khoom siv vuam

Vuam yas thiab hlau tsis tuaj yeem cia siab rau cov khoom siv vuam zoo tib yam. Cov cuab yeej tshwj xeeb yog qhov yuav tsum muaj. Qhov laj thawj tseem ceeb yog tias cov cuab yeej zoo tib yam tsis tuaj yeem tswj hwm lub zog tso tawm thiab qhov ntau ntawm thermal cuam tshuam.

Ordinary arc welders thiab cov chaw welders, uas tsom mus rau melting hlau ntawm qhov kub thiab txias, yuav ncaj qha hlawv cov yas thaum siv cov yas - hlau vuam thiab tsis tuaj yeem tsim ib qho kev sib raug zoo.

Ordinary yas - cov tshuab melting tsuas tuaj yeem ua kom sov yas thiab tsis tuaj yeem kho cov hlau nto lossis muab cov khoom siv hluav taws xob hauv zos. Vuam nrog cov tshuab no feem ntau ua rau detachment thiab sealing tsis ua hauj lwm.

Cov cuab yeej tshwj xeeb vuam, txawm li cas los xij, yog tsim los rau cov khoom siv ntoo khaub lig. Piv txwv li, ultrasonic yas - hlau welders siv siab - zaus vibrations (15 - 70kHz) kom mloog zoo zog ntawm qhov chaw tiv tauj. Qhov no tso cai rau cov yas yaj sai sai thiab nkag mus rau hauv cov pits me me ntawm cov hlau nto, ua kom muaj kev sib txuas ntawm cov tshuab thiab molecular - qib kev sib cog lus. Laser yas - hlau welders, ntawm qhov tod tes, siv lub siab directionality ntawm lasers precisely cua sov rau yas sab. Cov yas melts thiab adheres rau cov hlau, tsuas yog cov hlau saum npoo yog rhuab me ntsis kom tsis txhob deformation. Tsis tas li ntawd, cov cuab yeej tshwj xeeb kuj tau nruab nrog kev sib txuas ua ntej kev kho mob (xws li kev ntxuav cov ntshav thiab cov khoom siv roughening) txhawm rau txhim kho vuam lub zog.

 

III. Cov txiaj ntsig tseem ceeb ntawm cov cuab yeej tshwj xeeb: Sib npaug kev sib txuas lub zog thiab cov khoom ruaj khov

Qhov zoo ntawm cov yas tshwj xeeb - cov khoom siv hlau vuam tau pom hauv peb yam. Ua ntej, nws muaj zog controllability ntawm lub zog tso zis. Nws tuaj yeem kho qhov tsis zoo raws li hom yas (xws li PP, ABS) thiab cov khoom siv hlau (xws li txhuas, stainless hlau) kom tsis txhob muaj cov khoom puas. Qhov thib ob, nws muaj kev vuam zoo heev. Cov cuab yeej siv feem ntau tuaj yeem ua tiav kev ua haujlwm tsis tu ncua, uas tsim nyog rau ntau lawm. Thib peb, nws muaj kev sib txuas siab kev ntseeg siab. Lub welded sib koom ua ke tuaj yeem tiv taus qee qhov tensile quab yuam thiab kev vibrations tom qab vuam, ua tau raws li kev siv cov khoom lag luam. Piv txwv li, hauv kev tsim cov khoom siv hluav taws xob, cov khoom siv tshwj xeeb laser vuam tuaj yeem ua tiav kev sib txuas ntawm cov yas casings thiab hlau pins. Qhov ntsuas dej tsis zoo ncav cuag IP67, thiab kev pabcuam lub neej ntev dua li cov txheej txheem sib txuas ib txwm muaj.

Vuam yas thiab hlau yog qhov nyuaj, tab sis kev sib txuas zoo tuaj yeem ua tiav nrog cov cuab yeej tshwj xeeb. Cov cuab yeej siv tsis tau raws li qhov xav tau. Yog tias koj xav tau kev sib txuas ntawm cov khoom siv ntawm cov yas thiab hlau, PDKJ cov khoom tshwj xeeb ntawm cov khoom siv vuam tuaj yeem ua tau raws li qhov sib txawv ntawm cov khoom sib txawv, sib npaug kev sib txuas ntawm lub zog thiab kev tsim khoom, thiab muab kev ruaj ntseg rau kev tsim khoom.
