Peb txhua tus paub tias xim yog lub ntiaj teb ntawm xim, thiab xim siv tau txhua qhov chaw, yog li koj puas paub vim li cas xim thiaj siv? Cov haujlwm yog dab tsi? Qhov cuam tshuam yog dab tsi? Tsuas yog rau qhov zoo nkauj xwb? "Nyob ntawm khaub ncaws", phab ntsa kuj yog ib hom phiaj xwm ntsej muag rau tag nrho cov txheej txheem txhim kho tsev. Dhau li ntawm lub luag haujlwm ntawm qhov chaw, muaj lwm yam teebmeem dab tsi? Tom ntej no, tus neeg tsim khoom xim yuav qhia txog cov teebmeem ntawm xim rau cov neeg siv internet. saib.
Ua ntej, cov phab ntsa raug pleev xim nrog ib qho kev zoo nkauj ib zaug xwb
Tib neeg lub neej saj tau ntau thiab ntau dua, thiab cov tub lag luam txawj ntse tau nkag siab txog cov kev xav tau ntawm cov neeg siv khoom raws sijhawm, thiab kev kho kom zoo nkauj ntawm cov txheej txheem kuj tau dhau los ua ib qho tseem ceeb hauv kev txhim kho ntau yam. Tsuav koj xav tau, phab ntsa yog koj daim ntaub, lub menyuam hauv koj txhais tes yog koj txhuam, thiab koj tuaj yeem coj kev tshoov siab los rau hauv qhov tseeb txhua lub sijhawm.
Qhov thib ob, los tiv thaiv cov khoom kom ntev lub neej kev pabcuam
Cov chaw tsim xim tau hais tias xim zoo li cov tshuaj pleev ib ce thaum lub sijhawm kho dua tshiab, uas qhia txog qhov zoo nkauj ntawm lub tsev; nws npog cov txheej saum npoo thiab tsim cov zaj duab xis tiv thaiv rau ntawm qhov chaw ntawm lub tsev. Vim tias cov khoom raug rau huab cua, nws nyuaj rau zam kev ua haujlwm ntuj, thiab lawv raug oxygen thiab dej noo yaig, ua rau muaj ntau yam xwm txheej xws li kev puas tsuaj ntawm cov cement, kev xeb hlau, thiab kev lwj ntoo. Kev siv cov xim zoo los tswj qhov chaw ntawm cov khoom tuaj yeem tiv thaiv lossis ncua "kev laus" thiab ua kom lub neej ua haujlwm ntev dua;
1. Qee cov ntaub ntawv siv rau hauv kev tsim kho yog cov khoom siv uas yooj yim hlawv, thiab muaj qee qhov kev phom sij rau kev nyab xeeb. Vim li no, cov tub lag luam tau tsim ib txheej tshwj xeeb uas tiv thaiv hluav taws, uas tau pleev rau ntawm qhov chaw ntawm cov khoom siv uas yooj yim hlawv kom txo qhov yooj yim hlawv ntawm cov khoom siv, txhim kho qhov tiv thaiv hluav taws ntawm cov khoom siv, tiv thaiv kom tsis txhob muaj hluav taws kis mus, thiab txo qhov poob uas tshwm sim los ntawm qhov ntawd.
2. Rau tib neeg, dej yog qhov tseem ceeb tshaj plaws tom qab oxygen, thiab nws yog qhov tsis zam tsis tau los cuam tshuam nrog dej hauv lub neej txhua hnub. Cov chaw tsim khoom txheej hais tias qee cov khoom siv hauv tsev tau raug rau qhov dej noo ntev ntev, uas yooj yim kom ntub thiab ua rau lub neej ua haujlwm luv dua. Cov txheej tiv thaiv dej tau tshwm sim. Tom qab kho, ib txheej ntawm daim nyias nyias tiv thaiv dej uas muaj ductility, tiv thaiv tawg, tiv thaiv xau, tiv thaiv huab cua thiab lwm yam khoom tau tsim rau ntawm txheej hauv qab, yog li phab ntsa tuaj yeem hloov kho tau zoo rau kev hloov pauv ntawm huab cua thiab kub.
3. Cov khoom siv hlau tau dhau los ua ib qho ntawm cov khoom siv hauv tsev uas siv dav vim lawv cov qauv tawv thiab muaj zog heev. Txawm li cas los xij, thaum cov hlau kov cov khoom ib puag ncig xws li cua, chlorine, carbon dioxide, cov kua dej, noo noo, thiab lwm yam. Cov tshuaj lom neeg tuaj yeem tshwm sim uas ua rau xeb xws li xeb ntawm hlau, dub ntawm nyiaj, thiab ntsuab ntawm tooj liab. Qhov no tsis tsuas yog cuam tshuam rau qhov zoo nkauj ntawm lub tsev xwb, tab sis kuj txo qhov kev siv lub neej. Raws li tus neeg tsim khoom txheej, cov xim tiv thaiv xeb tau siv rau ntawm qhov chaw ntawm cov khoom, thiab tom qab cov zaj duab xis tau tsim, nws tuaj yeem lo rau ntawm qhov chaw ntawm cov khoom coated, tiv thaiv dej, oxygen thiab lwm yam corrosive ntau li ntau tau, txo nws cov permeability, thiab tiv thaiv cov khoom coated.
