Environmental Analysis of Plastics Siv nyob rau hauv Environmental Protection Equipment

Kev siv ib puag ncig rau plastics hauv cov cuab yeej tiv thaiv ib puag ncig feem ntau yog nyob ntawm cov khoom siv tiv thaiv corrosion, kub tsis kam, mechanical zog, thiab cov kev ua haujlwm tiag tiag ntawm cov khoom siv. Nyob rau hauv ib puag ncig engineering tej yaam num xws li pov tseg roj, kev kho dej phwj, tshuaj purification dej khib nyiab, thiab acid / alkali media tsheb thauj mus los, cov ntaub ntawv yas yog dav siv vim lawv lub teeb yuag, zoo corrosion kuj, thiab yooj yim ntawm kev ua. Piv txwv li, polypropylene (PP) yog haum rau ntau cov kua qaub / alkali khib nyiab roj txhuam cov yees, cov tshuaj cia tso tsheb hlau luam, thiab cov khoom siv kho dej khib nyiab, ua kom pom kev hloov tau zoo thaum sib cuag nrog ntau yam corrosive media; polyvinyl chloride (PVC) feem ntau yog siv rau hauv cov kav dej, qhov cua ducts, thiab qee qhov kub ntawm cov tshuaj lom neeg kev thauj mus los, tab sis nws qhov kub thiab txias thiab kev cuam tshuam tsis kam yog me ntsis txwv; polyethylene (PE) muaj qhov toughness zoo thiab cuam tshuam, ua rau nws tsim nyog rau qee qhov kev thauj mus los ntawm cov kav dej phwj, cov thawv ntim dej, thiab cov chaw txhawb nqa sab nraum zoov; polyvinylidene fluoride (PVDF) muaj cov tshuaj tiv thaiv corrosion siab thiab tuaj yeem siv rau hauv qee qhov kev mob corrosive uas xav tau cov khoom siv siab. Hauv kev siv tswv yim, qhov kev siv tau tsis tuaj yeem txiav txim siab los ntawm hom yas; Nws tseem yog ib qho tsim nyog los soj ntsuam cov ntaub ntawv xov xwm, concentration, kub, siab, thiab lub sijhawm sib cuag. Tshwj xeeb tshaj yog thaum kho high-concentration acid thiab alkali daws, dej khib nyiab uas muaj cov kuab tshuaj organic, los yog complex industrial khib nyiab gases, compatibility ntawm cov ntaub ntawv thiab cov nruab nrab yuav tsum tau paub tseeb hais tias ua ntej kom tsis txhob muaj cov khoom aging, deformation, cracking, los yog to vim xaiv cov khoom siv tsis zoo.

 

Ambient kub, cov khoom siv kev ntxhov siab, kev nyab xeeb sab nraum zoov, thiab kev ua haujlwm ntev kuj tseem cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov yas hauv cov khoom tiv thaiv ib puag ncig. Hauv qhov chaw ua haujlwm kub kub, qee cov yas yog qhov ua rau softening, txo qhov tawv nqaij, lossis qhov hloov pauv. Yog li ntawd, qhov kev siv ntau yam yuav tsum tau txiav txim siab raws li qhov ntev ntawm kev ua haujlwm kub ntawm cov khoom siv thiab cov cuab yeej tsim cov kev cai, tsis yog tsuas yog cia siab rau cov ntaub ntawv kub-lub sij hawm luv luv. Thaum siv sab nraum zoov, cov khoom siv yuav raug tshav ntuj, nag, cua, xuab zeb, thiab kub hloov mus rau lub sijhawm ntev. Qee cov yas yuav muaj hnub nyoog, ua nkig, lossis muaj kev poob qis ntawm cov khoom nto vim yog hluav taws xob ultraviolet. Yog li ntawd, cov ntaub ntawv uas muaj huab cua tiv thaiv yuav tsum raug xaiv raws li qhov xwm txheej tiag tiag, lossis kev tiv thaiv tsim nyog xws li shading, tiv thaiv txheej, thiab lwm yam kev tiv thaiv tsim nyog yuav tsum tau ua. Rau cov cuab yeej tiv thaiv ib puag ncig uas xav tau kev tiv thaiv qee qhov siab, kev cuam tshuam, lossis cov khoom siv kho tshuab, lub zog, nruj, tuab, thiab kev ntseeg siab ntawm cov kev sib txuas yuav tsum tau ua tib zoo xav kom tsis txhob deformation thiab kev puas tsuaj los ntawm kev ntxhov siab mus sij hawm ntev lossis kev teeb tsa tsis raug. Tsis tas li ntawd, nyob rau hauv cov xwm txheej xws li cov dej khib nyiab pov tseg, cov pa roj purification towers, thiab cov khoom siv tshuaj lom neeg, yuav tsum tau them nyiaj rau kev sib raug zoo ntawm cov yas thiab cov khoom txhawb nqa xws li cov ntsaws ruaj ruaj, kav dej, thiab li qub kom ruaj khov ntawm tag nrho cov kab ke. Zuag qhia tag nrho, plastics siv nyob rau hauv ib puag ncig tiv thaiv cov cuab yeej tsim nyog rau ntau yam corrosive ib puag ncig thiab cov pa hauv kev lag luam; Txawm li cas los xij, lawv cov txiaj ntsig zoo sib xws nrog kev xaiv cov khoom siv, kev tsim khoom zoo, cov txheej txheem kev teeb tsa, thiab kev tswj xyuas kev tswj xyuas. Tsuas yog los ntawm kev xaiv cov ntaub ntawv tsim nyog raws li kev ua haujlwm tshwj xeeb thiab tshuaj xyuas cov khoom siv tsis tu ncua, cov pob qij txha welded, cov ntsiab lus sib txuas, thiab cov ntsaws ruaj ruaj tuaj yeem txo qhov kev pheej hmoo ntawm cov cuab yeej tsis ua haujlwm thiab kev pabcuam lub neej ntev.
