Cov tshuaj nplaum yog siv los txo qhov tsis kam ntawm cov ntsiab lus hluav taws xob.
Yuav muab tshuaj rau dab tsi
Txawm tias nyob rau hauv ib nrab ntawm lub xyoo pua 20th, cov kws tshawb fawb tau suav tias qhov poob ntawm hluav taws xob hauv txhua qhov chaw tsim khoom muaj txog li 10% ntawm tag nrho cov hluav taws xob siv. Tus nqi no nce ntxiv raws li cov khoom siv hnub nyoog thiab cov xov hlau tsis zoo.
Txoj hauv kev yooj yim tshaj plaws los txo qhov kev poob qis yam tsis muaj nyiaj txiag loj yog kev siv hluav taws xob tshwj xeeb txhais tau tias. Tsis tas yuav kho cov cuab yeej lossis hloov cov xaim.
Kev tiv tauj hluav taws xob muaj lub neej. Thiab nws shrinks raws li kev sib cuag tiv thaiv hloov. Thaum raug hluav taws xob, qhov sib txuas ntawm cov xov hlau pib sov. Qhov no tuaj yeem ua rau hluav taws kub. Kev txheeb cais hais tias nyob rau hauv 10% ntawm cov neeg mob, muaj xwm txheej tshwm sim precisely vim yog kev puas tsuaj ntawm kev sib cuag ntawm cov hluav taws xob network. Thiab qhov kev puas tsuaj ntawm hom no tshwm sim precisely vim yog ntau dhautxwv ntawm hluav taws xob tsis kam.
Rau kev kho mob ntawm kev sib cuag, cov qauv muab rau cov tshuaj xws li lithol, cyatim, technical vaseline. Txhua tus ntawm lawv muaj lub hauv paus rog. Vim li no, xws li cov nyiaj yaj thiab hlawv tawm, tawm hauv kev sib cuag tsis muaj kev tiv thaiv. Raws li kev hloov pauv rau lawv, cov tshuaj tiv thaiv kab mob tau siv tsis ntev los no tau nce ntxiv.
tswvyim
Kev muab tshuaj txhuam tso cai rau koj ua kom lub neej ntawm cov xov hluav taws xob tiv tauj mus txog xya xyoo. Nws txo los ntawm ib nrab ntawm tus nqi ntawm kev sib cuag tiv thaiv ntawm cov ntsiab lus ntawm cov hluav taws xob tiv tauj. Cov cuab yeej no ua haujlwm hauv qhov kub txog li 350-4000 degrees. Nyob rau hauv cov xwm txheej zoo li no, nws tso cai rau koj khaws tag nrho cov haujlwm ua haujlwm ntawm kev sib txuas lus.
Cais, muaj xws li cov khoom xws li cov tshuaj tiv thaiv corrosion. Ntxiv rau cov dej num tseem ceeb ntawm kev txo kev tiv thaiv kev tiv thaiv, nws tiv thaiv kev sib cuag los ntawm kev ya raws thiab kev ua phem rau ib puag ncig.
Cov roj hluav taws xob hluav taws xob tseem ua haujlwm txuag hluav taws xob. Cov kws tshaj lij suav tias tsuas yog siv 1 kg ntawm cov khoom tuaj yeem txuag tau txog li 100 txhiab kW hluav taws xob ib xyoos.
Scope of application
Kev muab tshuaj txhuam rau kev sib cuag yog siv ntau qhov chaw ntawm kev tsim khoom thiab kev lag luam. Cov tseem ceeb yog:
Metallurgical
Petrochemical
Mining and processing plant
Cov nroj tsuag muaj zog ntau yam(thermal, nuclear, hydro)
khoom siv tub rog
Utilities
Transport
Kho cov hluav taws xob hluav taws xob
Kev faib tawm
Cov khoom siv hluav taws xob muaj ob yam. Lawv txawv ntawm ib leeg hauv txoj kev uas lawv cuam tshuam rau kev sib cuag:
Passive (nws tseem hu ua nruab nrab) yog ib hom kev tiv thaiv uas yuav tiv thaiv kev sib cuag los ntawm oxidation nyob rau hauv lub zog ntawm atmospheric oxygen. Cov pab pawg no suav nrog KBT kev sib txuas lus muab tshuaj
Active tsis cuam tshuam rau cov hlau ntawm cov xov hlau, tab sis cuam tshuam rau thaj chaw oxidized nyob rau saum npoo
Siv cov khoom
Kev muab tshuaj txhuam yog yooj yim siv. Ua ntej tshaj plaws, qhov chaw uas cov khoom siv yuav tsum tau degreased thiab qhuav.
Tom ntej no, cov nplej zom nws tus kheej tau npaj. Raws li txoj cai, nws muaj ob yam khoom: hmoov nrog ntxiv ntawm cov hlau, cov kua rau diluting cov hmoov. Yog li ntawd, cov khoom yuav tsum tau txuas nrog. Qhov no yog ua nyob rau hauv ib lub thawv qhuav. Koj tuaj yeem txawm nyob ntawm daim duab los qhia, yog tias qhov ntau me me. Cov tshuaj txhuam hniav yuav tsum muaj qhov sib xws zoo ib yam li cov tshuaj txhuam hniav.
Cov tshuaj nplaum yog siv rau qhov chaw npaj rau hauv ib txheej 2-3 hli tuab. Thaum txuas cov neeg sib cuag, lawv qhov kawg tsuas yog qis dua rau hauv lub cuab yeej.
Nws yog qhov tsim nyog los ua haujlwm nrog cov nplej ua tiav sai sai. Nws seizes hauv ob feeb. Lub sijhawm qhuav puv yog ob teev.
Ua koj tus kheej pasta
Cov tshuaj nplaum yog muag hauvib tug ntau yam ntawm cov khoom los ntawm ntau yam manufacturers. Tab sis koj tuaj yeem tsim koj tus kheej.
Lub ntsiab ntawm cov kua nplaum yog hluavtaws cob. Nws tsis ua hluav taws xob hauv nws daim ntawv ntshiab. Yog li ntawd, cov khoom ntawm cov hlau yog ntxiv rau nws - kub, tooj liab, nyiaj, npib tsib xee. Txhawm rau kom muaj hluav taws xob zoo, cov hmoov ntim yuav tsum yog tsawg kawg 70%.
Nyiaj yog feem ntau siv. Qhov kev xaiv no tsuas yog nyob ntawm kev lag luam ntawm qhov teeb meem. Txoj kev yooj yim tshaj plaws thiab pheej yig tshaj kom tau txais nws yog los ntawm cov tshuaj tiv thaiv ntawm formalin txo. Rau qhov no, ib feem ntawm nyiaj nitrate thiab ib feem ntawm formalin (1%) yog noj. Lawv sib tov yog rhuab mus rau ib tug kub ntawm 80 degrees. Tom qab ntawd, ammonia (5%) ntxiv rau ntawd. Raws li qhov tshwm sim ntawm cov tshuaj tiv thaiv, ib qho xim dub-xim nyiaj precipitate yuav poob rau hauv qab. Cov dej nag no yog lim, ntxuav thiab qhuav.
Thaum tag nrho cov khoom xyaw npaj txhij, koj tuaj yeem ua noj cov nplej zom. Ua li no, muab 100 grams epoxy resin, 250 grams nyiaj hmoov, 10 grams dibutyl flatate (kom cov resin ntau npaum li cas). Ua ntej siv, ntxiv 10 grams ntawm polyethylenepolyamine ua ib lub hardener. Yog tsis muaj nws, qhov sib tov tuaj yeem khaws cia tsis tu ncua.
Koj tuaj yeem ua kom cov hluav taws xob ua kom zoo dua yog tias koj qhuav nws tom qab thov ntawm qhov kub siab (txog 100 degrees).
Kev tawm xov xwm yog cov tshuaj uas yuav tsum tau ua nrog kev ceev faj txog kev nyab xeeb. Cov tshuaj nplaum yuav tsum tsis txhob nkag mus rau hauv daim tawv nqaij thiab mucous daim nyias nyias.plhaub. Yog tias qhov no tshwm sim, ntxuav kom huv nrog dej sov soapy.
