Putty hmoov yog cov khoom siv siv hauv tsev, dav siv hauv phab ntsa theem thiab kho kom zoo nkauj. Hauv nws cov txheej txheem tsim khoom, hydroxypropyl methylcellulose (HPMC) yog ib qho tseem ceeb ntxiv uas tuaj yeem txhim kho qhov adhesion thiab kev tsim kho ntawm putty hmoov. Txawm li cas los xij, kev xav txog ib puag ncig kev koom tes hauv kev tsim cov hmoov putty yog qhov tseem ceeb heev, thiab nws yuav tsum tau ua tib zoo xav txog ntau yam xws li kev xaiv raw khoom, txheej txheem tsim khoom, thiab pov tseg pov tseg kom txo tau qhov tsis zoo ntawm ib puag ncig.
Kev xaiv raw khoom
Cov khoom tseem ceeb ntawm cov hmoov putty yog cov khoom siv tsis muaj zog, xws li calcium carbonate, talcum hmoov, cement, thiab lwm yam. Kev khawb thiab kev tsim cov ntaub ntawv no yuav muaj qee yam cuam tshuam rau ib puag ncig, xws li kev siv av thiab kev puas tsuaj los ntawm ecological. mining. Yog li ntawd, xaiv ib puag ncig tus phooj ywg cov khoom siv raw khoom thiab sim siv cov khoom siv txuas ntxiv lossis rov ua dua tshiab yog cov kev ntsuas tseem ceeb los txo qhov cuam tshuam ib puag ncig.
HPMC, raws li cov organic compound, feem ntau tau los ntawm kev kho tshuaj ntawm cellulose. Cellulose yog ib yam khoom siv polymer uas muaj nyob hauv cov phab ntsa ntawm cov nroj tsuag. Txhawm rau txo qhov cuam tshuam rau ib puag ncig, kev tsim tawm ntawm HPMC tuaj yeem siv cov txheej txheem tshuaj lom neeg ib puag ncig thiab txo qis kev siv thiab emission ntawm cov tshuaj phem. Piv txwv li, dej-raws li cov kuab tshuaj raug xaiv los ntawm cov kuab tshuaj organic los txo cov emission ntawm volatile organic compounds (VOCs).
Cov txheej txheem ntau lawm
Cov txheej txheem ntawm cov hmoov putty muaj ntau qhov sib txuas xws li kev sib xyaw, sib tsoo, tshuaj ntsuam xyuas, thiab ntim cov khoom siv raw. Hauv cov kev sib txuas no, cov pa phem xws li plua plav, suab nrov, thiab dej khib nyiab tuaj yeem tsim tawm. Yog li ntawd, kev tswj hwm ib puag ncig zoo yog ib txoj hauv kev tseem ceeb los xyuas kom muaj kev tiv thaiv ib puag ncig ntawm cov txheej txheem tsim khoom.
Cov khoom siv ntau lawm yuav tsum muaj kev sib khi zoo kom txo tau cov plua plav tawm. Nyob rau tib lub sijhawm, cov khoom siv tshem tawm cov plua plav zoo xws li hnab plua plav collectors thiab electrostatic plua plav collectors tuaj yeem ntsia tau los txo cov emission ntawm plua plav thaum lub sijhawm tsim khoom. Qhov thib ob, lub suab nrov yuav tsum raug txo kom tsawg thaum lub sijhawm tsim khoom, thiab kev ntsuas suab nrov thiab kev ua kom ntsiag to tuaj yeem ua tau, xws li siv cov khoom siv suab rwb thaiv tsev thiab txhim kho silencers. Rau kev kho cov dej khib nyiab, lub cev, tshuaj, thiab tshuaj lom neeg siv thev naus laus zis xws li nag lossis daus, pom, thiab cov pa roj carbon activated tuaj yeem siv los kho cov dej khib nyiab kom tau raws li cov qauv ua ntej tso tawm.
Hauv cov txheej txheem tsim khoom, kev tswj hwm kev siv hluav taws xob kuj yog ib qho tseem ceeb rau kev saib xyuas ib puag ncig. Ib tug loj npaum li cas ntawm hluav taws xob thiab hluav taws xob hluav taws xob yog siv nyob rau hauv cov txheej txheem ntawm cov hmoov putty. Yog li ntawd, kev siv cov khoom siv hluav taws xob txuag thiab txuag hluav taws xob thiab cov txheej txheem yog ib qho kev ntsuas tseem ceeb los txo kev siv hluav taws xob thiab txo kev cuam tshuam ib puag ncig. Piv txwv li, cov khoom siv sib tsoo hluav taws xob txuag hluav taws xob thiab cov khoom siv sib xyaw zoo tuaj yeem siv tau.
Kev kho khib nyiab
Ib qho nyiaj pov tseg yuav raug tsim nyob rau hauv cov txheej txheem ntawm cov hmoov putty, nrog rau cov khoom tsis tsim nyog, cov khoom seem, cov khoom ntim pov tseg, thiab lwm yam. Yuav kom txo tau qhov cuam tshuam rau ib puag ncig, kev kho cov pov tseg yuav tsum ua raws li cov hauv paus ntsiab lus ntawm kev txo qis, peev txheej. kev siv, thiab tsis muaj teeb meem.
Kev tsim cov khoom pov tseg tuaj yeem raug txo los ntawm kev ua kom zoo ntawm cov txheej txheem ntau lawm. Piv txwv li, kev txhim kho qhov raug thiab kev ruaj ntseg ntawm cov khoom siv ntau lawm tuaj yeem txo cov tiam ntawm cov khoom tsis tsim nyog. Qhov thib ob, cov khoom pov tseg tuaj yeem rov ua dua tshiab, xws li cov khoom siv rov ua dua tshiab thiab rov ua dua cov khoom ntim pov tseg. Rau cov khib nyiab uas tsis tuaj yeem rov ua dua tshiab, kev ntsuas kev kho mob tsis zoo xws li incineration thiab landfill tuaj yeem siv tau, tab sis nws yuav tsum tau ua kom ntseeg tau tias cov kev kho mob no ua tau raws li kev tiv thaiv ib puag ncig kom tsis txhob muaj kev ua qias tuaj.
Ua raws li kev tiv thaiv ib puag ncig
Putty hmoov manufacturers yuav tsum nruj me ntsis raws li lub teb chaws thiab cheeb tsam ib puag ncig tiv thaiv cov cai thiab cov kev cai, tsim kom muaj ib tug zoo ib puag ncig tswj system, thiab xyuas kom meej qhov kev siv ntawm ntau yam kev tiv thaiv ib puag ncig. Ua raws li kev saib xyuas ib puag ncig tsis tu ncua kom pom raws sijhawm thiab daws teeb meem ib puag ncig. Tsis tas li ntawd, cov neeg ua haujlwm kev paub txog kev paub txog ib puag ncig yuav tsum tau ntxiv dag zog los txhim kho kev tiv thaiv ib puag ncig kev paub thiab kev nkag siab ntawm lub luag haujlwm ntawm txhua tus neeg ua haujlwm thiab koom tes txhawb kev tsim ntsuab ntawm kev lag luam.
Kev txiav txim siab ib puag ncig hauv cov hmoov nplej ntau lawm npog ntau yam xws li kev xaiv raw khoom, kev tswj cov txheej txheem ntau lawm, thiab pov tseg pov tseg. Los ntawm kev siv cov ntaub ntawv zoo ib puag ncig, txhim kho cov txheej txheem tsim khoom, ntxiv dag zog rau kev tswj cov khib nyiab, thiab ua raws li cov cai thiab cov cai ntawm ib puag ncig, putty hmoov manufacturers tuaj yeem txo qhov tsis zoo ntawm ib puag ncig thiab txhawb kev loj hlob ntsuab thiab ruaj khov.
