tooj dag rodsyog cov khoom zoo li tus pas nrig ua los ntawm tooj liab thiab zinc alloys, muaj npe rau lawv cov xim daj.Brass nrog cov ntsiab lus tooj liab ntawm 56% mus rau 68% muaj cov ntsiab lus melting ntawm 934 txog 967 degrees.Brass muaj cov khoom siv zoo thiab hnav tsis kam, thiab tuaj yeem siv los tsim cov cuab yeej precision, nkoj qhov chaw, phom plhaub, tsheb qhov chaw, khoom siv kho mob, khoom siv hluav taws xob thiab ntau yam khoom siv txhawb nqa, tsheb synchronizer iav rings, Marine twj, li qub, cov khoom siv, kev sib txhuam accessories, thiab lwm yam.
Cov pas nrig tooj dag nrog cov ntsiab lus zinc sib txawv kuj yuav muaj xim sib txawv.Piv txwv li, yog cov ntsiab lus zinc yog 18% -20%, nws yuav yog xim liab-daj, thiab yog cov ntsiab lus zinc yog 20% -30%, nws yuav yog xim av-daj.Tsis tas li ntawd, tooj dag muaj lub suab tshwj xeeb thaum ntaus, yog li Eastern gongs, cymbals, tswb, horns thiab lwm yam suab paj nruag, nrog rau cov twj paj nruag Western yog txhua yam ua los ntawm tooj dag.
Dab tsi yog kev ua haujlwm tshwj xeeb ntawm kev tswj xyuas zoo ntawm cov pas nrig tooj dag?
1. Cov cuab yeej muab tso rau ntawm txoj siv tooj dag yuav tsum tau tshuaj xyuas thiab pom zoo los ntawm tus thawj saib xyuas ua ntej cov pob zeb nchuav.
2. Lub vuam zoo ntawm txoj hlua siv tooj dag yuav tsum tau kuaj xyuas.Thaum tus thawj saib xyuas xav tias tsim nyog, kev tshuaj xyuas cov roj to yuav tsum tau ua.Tom qab dhau qhov kev xeem, cov roj paug yuav tsum tau ntxuav.
3. Lub formwork yuav tsum ruaj khov, thiab cov formwork ntawm ob sab ntawm daim ntawv yuav tsum tau txais kev txhawb los ntawm "Ω"cov duab los yog lwm yam kev txhawb nqa kom tsis txhob muaj kev sib raug zoo thiab kev xau ntawm slurry vim qhov deformation ntawm formwork.
4. Ib qho qauv tshwj xeeb tshwj xeeb yuav tsum tau siv ntawm txoj siv tooj dag kom paub meej tias daim ntawv tau ruaj khov thiab cov pob qij txha tsis tawg.
5. Thaum lub sij hawm pouring txheej txheem, tsis txhob tsub zuj zuj ntawm loj aggregates nyob rau hauv lub tooj dag siv, thiab co ua tib zoo xyuas kom meej tias cov pob zeb ntawm lub pob zeb yog ntom.
6. Npaj cov txheej txheem nchuav thiab vibrating kom tsim nyog, thiab ua tib zoo saib xyuas kom tsis txhob muaj cov ntshav tawm ntawm txoj siv tooj dag.
7. Thaum lub sij hawm ua cov pob zeb, tus neeg cog lus yuav tsum npaj cov neeg ua haujlwm tshwj xeeb los tshuaj xyuas thiab tswj.Tus thawj saib xyuas yuav tsum ntxiv dag zog rau kev tshuaj xyuas ntawm qhov chaw, thiab yog tias pom muaj qhov sib txawv, tus neeg cog lus yuav tsum tau qhia kom kho nws raws sijhawm.
8. Ua tib zoo saib xyuas qhov backfilling thiab compaction ntawm cov pob zeb ntawm qhov qis ntawm txoj siv tooj dag, thiab tsim nyog siv oblique insertion thiab kab rov tav vibration.
