Sandblasting xeb tshem tawm txheej txheem tag nrho xauv

Vim li cas qee cov khoom siv tshuab muaj qhov loj ntawm cov xim tev thiab xeb tom qab lub sijhawm ntev, thaum qee cov khoom siv tau ntev heev? Hnub no, cia peb tham txog cov kauj ruam tsim nyog rau cov xim zoo nkauj ua ntej pleev xim - tshem tawm xeb !!!

1. Vim li cas peb thiaj li yuav tsum ua cov kauj ruam no rau cov xim zoo nkauj ntawm cov tshuab thoob ntiaj teb?

· Tshem tawm xeb, vuam slag tshem tawm, thiab tshem tawm cov xim qub
Tom qab vuam thiab ua tiav, lub boom feem ntau muaj xeb me ntsis, nplai, vuam slag, thiab lwm yam. Kev sib tsoo zoo ib yam tsis muaj txiaj ntsig thiab tsis tuaj yeem tshem tawm tag nrho. Sandblasting tuaj yeem tshem tawm tag nrho cov pa phem ntawm qhov chaw thiab rov ua kom lub ntsej muag ci.

· Nto primer muaj nuj nqi
Qhov me me concave thiab convex ntxhib nto sab laug los ntawm sandblasting muab ib qho "adhesion anchor point" ua rau cov primer tom ntej muaj zog dua thiab tsis yooj yim rau poob.

· Txo kev ntxhov siab sab hauv
Kev kub ceev cuam tshuam tuaj yeem tso qee qhov kev ntxhov siab seem tom qab vuam thiab txo qhov kev pheej hmoo ntawm kev qaug zog tawg.

2. Yuav ua li cas tawg? Media Xaiv Phau Ntawv Qhia

Common sandblasting media muaj xws li:

· Hlau xuab zeb / hlau txhaj tshuaj: hnyav-lub luag haujlwm xeb tshem tawm, kev ua haujlwm siab, tab sis cov khoom siv siab (recycling thiab ua cov xov xwm hnyav).

· iav hlaws / txhuas xuab zeb / zirconium xuab zeb / garnet: nruab nrab lub zog, yooj yim los tswj cov nyhuv primer.

· Yas los yog organic media (xws li walnut shells, pob kws cobs): maj mam tu, tsis muaj kev puas tsuaj rau lub substrate, haum rau cov ntsiab lus los yog yooj yim deformed qhov chaw.

3. Dry spraying vs. ntub txau: xaiv qhov tsim nyog rau kev thaj yeeb nyab xeeb

Cov tshuaj tsuag qhuav (Qhov zoo: tshem tawm xeb sai, tus nqi qis, kev ua haujlwm siab; Qhov tsis zoo thiab kev txwv: cov plua plav ya loj, yuav tsum tau them nyiaj rau kev tiv thaiv ib puag ncig thiab qhov cua.)

Kev ntub dej ntub dej (Qhov zoo: txo cov plua plav pom tseeb, txo cov xuab zeb raug mob thiab cuam tshuam zoo li qub; Qhov tsis zoo thiab cov kev txwv: cov cuab yeej nyuaj, tus nqi siab dua me ntsis, kev kho dej xav tau kev xav ntxiv.)

Qhuav tshuaj tsuag yog feem ntau siv nyob rau hauv boom factories, uas yog npaum thiab ceev; tab sis yog tias muaj cov kev cai rau kev tswj hwm ib puag ncig thiab plua plav, lossis nyob rau lub caij ntuj nag / kaw ib puag ncig, kev txau ntub dej yog lwm txoj hauv kev zoo dua.

4. Cov txheej txheem Sandblasting, tsis muaj kauj ruam ploj

1) Kev tiv thaiv kev tiv thaiv
Siv daim kab xev los yog cov ntaub thaiv npog los tiv thaiv qhov tsis yog tshuaj tsuag, xws li hydraulic interfaces thiab sealing rings.

2) Lub chav tshuaj tsuag yog nyob rau hauv qhov chaw thiab zoo ventilated
Siv chav tshuaj tsuag lossis qhib chaw ua haujlwm kom ntseeg tau tias cov plua plav nqus tawm hauv lub sijhawm.

3) Teem parameter
Kho lub siab rau 90-100 psi (kwv yees li 6-7 bar), thiab khaws cov tshuaj tsuag txog 10-15cm ntsug rau saum npoo.

4) Txau theem
cheb tusyees thiab maj mam, maj mam npog, thiab cuam tshuam nrog cov plua plav yooj yim thiab cov ces kaum tuag; xuab zeb hais cuam tshuam thiab tev tawm cov kab mob ntawm cov kab mob ntawm kev kub ceev.

5) Xuab zeb rov qab
Lawv feem ntau yog kaw-circuit circulation systems, lim plua plav thiab rov siv cov xov xwm los txo cov khib nyiab.

6) Ntxuav plua plav
Tom qab txau, siv cov cua compressed los yog nqus plua plav tshem tawm kom huv si.

5. Ntau yam txiaj ntsig ntawm cov txheej txheem

· Amazing efficiency: thawj xim ntawm cov hlau yuav rov qab tau nyob rau hauv ob peb feeb, thiab welds thiab xeb yuav sai sai ntxuav;

· Ntev-ntev txheej: qhov ntxhib saum npoo txhim kho qhov kev tiv thaiv ntawm tev thiab ua kom lub zog ntawm cov xim zoo dua;

· Kev saib xyuas yooj yim: kev tswj xyuas yooj yim dua tom qab sandblasting thiab txhim kho corrosion kuj;

· Muaj kev zoo nkauj: tom qab sandblasting, ib qho "matte" zoo nkauj nthuav tawm, uas yog ob qho tib si tactile thiab pom.

6. Cov lus qhia txog kev nyab xeeb

Sandblasting yog txias, tab sis nws kuj muaj qhov pheej hmoo zais:

· Cov neeg ua haujlwm yuav tsum hnav lub qhov ncauj qhov ntswg, tiv thaiv kev hnov ​​​​lus, thiab hnab looj tes hnyav

· Siv cov xov xwm tsis muaj tshuaj lom kom tsis txhob muaj kev phom sij rau kev ua haujlwm

· Plua plav-intensive ib puag ncig yuav tsum tau cais tawm, hluav taws-pov thawj, thiab tawg-pov thawj

· Hloov cov nozzles tsis tu ncua: hnav thiab tsim kua muag yuav txo tau efficiency thiab ua rau cov xuab zeb pov tseg

Sandblasting thiab phau ntawv sib tsoo tsis yog ua phem rau ib leeg. Hloov chaw, kev siv ntxiv tuaj yeem txhim kho kev ua haujlwm

Cov lus pom zoo

· Rough processing stage: thawj zaug siv phau ntawv sib tsoo rau cov txheej txheem vuam spatter cheeb tsam thiab ntxhib npoo.

· Batch processing stage: Sandblasting yog siv rau thaj chaw loj, uas muaj txiaj ntsig zoo thiab muaj adhesion zoo.

· Fine stage: fine-tune and grind me defects dua, thiab thaum kawg tswj cov plua plav thiab ntxuav qhov chaw.

Rau excavator caj npab, sandblasting yog ib qho kev ua tau zoo, zoo thiab corrosion-resistant tu. Lub hauv paus tseem ceeb yog: txau tawm cov kab xeb + tsim kom muaj qhov ntxhib ntxhib + txhim kho xim adhesion, ntxiv los ntawm kev ziab / ntub dej, xaiv qhov nruab nrab thiab kev tiv thaiv kev nyab xeeb. Cov txheej txheem yog qhov zoo kawg li.

Cov kauj ruam no txhim kho qhov zoo thiab kav ntev ntawm tag nrho cov txheej txheem casting / tsim khoom. Yog tias koj xav paub ntau ntxiv txog cov khoom siv sandblasting qauv, kev tsim kho video lossis cov khoom siv, koj tuaj yeem txuas ntxiv sib tham!
