Vim li cas cov phuam da dej nyob rau hauvcov chaw ntxhua khaub ncawsyooj yim puas dua li lwm cov ntaub pua chaw pw? Txawm tias ntxuav, tshem dej tawm, thiabkev ziab, puas muaj tej yam ua rau puas tsuaj?
Qhov Zoo ntawm Cov Khoom Siv Khaub Ncaws
● Tshuab Ntxuav Khaub Ncaws Lag Luam
Lub nruas sab hauv ntawm ib qhotshuab ntxhua khaub ncaws lag luamyog ua los ntawm cov hlau tsis xeb los ntawm kev vuam. Lub phaj ib puag ncig yog punched nrog cov qhov me me, thiab thaum lub sijhawm tsim khoom, kev kho kom deburring yuav tsum tau ua rau sab nraub qaum ntawm cov qhov no. Txawm li cas los xij, yog tias qhov zoo ntawm cov txheej txheem no tsis zoo thiab muaj ntau lub burrs tseem tshuav lossis ib qho burrs tsis kho, nws yuav ua rau cov ntaub snags.
Lwm qhov ua tau yog tias qhov kev puas tsuaj yog tshwm sim los ntawm qhov sib txawv ntawm cov pob qij txha ntawm cov tav V-zoo li ntawm lub nruas sab hauv thiab lub phaj ib puag ncig. Thaum lub sijhawm ntxuav, lub nruas sab hauv yuav deform vim yog thermal nthuav dav thiab contraction. Qee qhov sib txawv me me hauv lub nruas sab hauv feem ntau nthuav dav tom qab cua sov. Yog tias qhov sib txawv tsis sib npaug, thaum phuam da dej raug ntes rau hauv qhov sib txawv dav dua thiab raug yuam los ntawm qhov sib txawv nqaim dua thaum lub nruas sab hauv tig, nws yuav raug dua.
Cov nruas sab hauv ntawm cov tshuab ntxhua khaub ncaws yog tsim los ntawm kev vuam.
Qee lub tshuab ntxuav qhov av siv cov roj hlau arc vuam (GMAW) thaum lub sijhawm vuam, uas ua rau cov vuam tawg. Qhov no yooj yim ua rau sab hauv lub nruas tsis sib npaug uas nyuaj rau ntxuav. Kev vuam argon arc tuaj yeem zam cov teeb meem saum toj no.
Tsis tas li ntawd xwb, yog tias tsis muaj zog vuam txaus ces tej zaum yuav ua rau muaj qhov tawg hauv qee qhov chaw. Qhov no kuj tseem ua rau cov phuam da dej puas vim tias cov phuam da dej muaj cov qauv voj voog thiab yooj yim dua rau kev sib txuas.
Qee lub tshuab ntxhua khaub ncaws siv ib sab vuam, yog li nws nyuaj rau lav qhov vuam zoo. Yog li ntawd, tib neeg yuav tsum tshuaj xyuas cov ntsiab lus ntxaws no thaum xaiv thiab yuav cov khoom siv ntxhua khaub ncaws.
Kev siv cov tshuaj ntxuav tes
● Ntxuav Tsis Tag
Yog tias kev ntxuav thaum lub sijhawm ntxhua khaub ncaws tsis txaus, txawm hais tias qhov alkalinity yuav tsis ua rau cov paj rwb ntshiab puas tsuaj, cov tshuaj ntxuav alkaline tseem nyob hauv cov phuam phuam. Qhov no ua rau phuam hloov xim grey thiab tawv tom qab ziab, thiab nws qhov mos yuav txo qis. Nws yuav ua rau cov phuam puas tsuaj sai dua thaum siv thiab thauj mus los.
● Cov Khoom seem ntawm Chlorine Bleach
Yuav tsum ntxiv cov tshuaj chlorine bleach raws li qhov sib piv. Kev siv tshuaj ntau dhau, kev tswj qhov kub tsis zoo, lossis kev ntxuav tsis zoo ua rau muaj cov tshuaj chlorine seem. Qhov no yuav ua rau cov phuam da dej poob cov xov thiab thaum kawg tawg.
● Kev Siv Tshuaj Neutralizer
Thaum kawg, cov tshuaj no yuav raug ntxiv rau hauv cov tshuaj ntxuav khaub ncaws. Tom qab ntxiv cov tshuaj no lawm, nws yuav tshem tawm cov tshuaj alkaline me me thiab cov tshuaj chlorine bleach uas tseem tshuav hauv cov ntaub uas tau ntxuav thiab tom qab yaug. Nws yuav yaj cov hlau ions hauv dej. Yog tias siv cov tshuaj no kom raug, cov ntaub linen yuav nyob nruab nrab ntawm 5.5 thiab 6.5, uas yog sib xws nrog cov pH ntawm daim tawv nqaij. Nws muaj kev nyab xeeb rau tib neeg, thiab cov ntaub tseem siv tau ntev.
Txawm li cas los xij, ntau lub chaw ntxhua khaub ncaws nrhiav kev mos mos ntau dhau thiab ntxiv ntau cov tshuaj neutralizer tsis raug. Cov seem ntawm cov tshuaj ntxuav acid yuav txo qhov ruaj khov ntawm cov phuam.
Yog tias cov chaw ntxhua khaub ncaws siv cov tshuab ntxhua khaub ncaws hauv kev lag luam los ntxuav, lawv yuav tsum tau ntim cov tshuab raws li qhov ntim khoom txheem ntau li ntau tau.
