Puas yog hluav taws xob ntoo muaj tshuaj lom? Hluav taws xob ntoo yog thermosetting yas ua los ntawm polymerization ntawm phenolic tebchaw thiab formaldehyde. Vim nws cov khoom zoo heev xws li thermal stability, hnav tsis kam, rwb thaiv tsev, thiab lwm yam, nws tau siv dav hauv ntau yam. Txawm li cas los xij, cov lus nug ntawm seb cov ntoo hluav taws xob puas muaj tshuaj lom tau ib txwm muaj kev txhawj xeeb. Kab lus no yuav tshawb txog kev nyab xeeb ntawm cov ntoo hluav taws xob los ntawm ntau qhov kev xav thiab txheeb xyuas nws cov laj thawj.
1. Toxic kawm txog hluav taws xob ntoo
Nyob rau hauv ob peb lub xyoo dhau los, ntau tus kws tshawb fawb tau kawm txog toxicity ntawm hluav taws xob ntoo. Kev tshawb fawb tau pom tias cov ntoo hluav taws xob tsis muaj tshuaj lom nyob rau hauv ib txwm siv. Txawm li cas los xij, thaum hluav taws xob ntoo decomposes ntawm qhov kub siab, nws tsim qee yam tshuaj lom xws li formaldehyde thiab phenol. Cov tshuaj lom no muaj kev phom sij rau tib neeg lub cev thiab tuaj yeem ua rau ua pa ua pa, ua xua, mob taub hau, thiab lwm yam tsos mob. Yog li ntawd, thaum siv cov khoom siv hluav taws xob ntoo, nws yog ib qho tsim nyog kom tsis txhob muaj qhov kub thiab txias los tiv thaiv kev tsim cov tshuaj lom.
2. Kev nyab xeeb ntawm cov khoom siv hluav taws xob
Txawm hais tias hluav taws xob ntoo tuaj yeem tsim cov tshuaj lom ntawm qhov kub thiab txias, cov khoom siv hluav taws xob hluav taws xob muaj kev nyab xeeb nyob rau hauv ib txwm siv. Qhov no yog vim hluav taws xob ntoo muaj thermal stability zoo thiab muaj peev xwm tswj tau lub cev thiab tshuaj lom neeg ruaj khov ntawm qhov kub thiab txias. Tsis tas li ntawd, qhov saum npoo ntawm cov khoom siv ntoo yog du, tsis yooj yim rau cov kab mob, thiab yooj yim los ntxuav, yog li lawv tau siv dav hauv cov khoom noj, kev kho mob, kev tu cev thiab lwm yam kev lag luam. Thaum siv cov khoom siv hluav taws xob ntoo, nws yog ib qho tseem ceeb uas yuav tsum tau ua kom huv si thiab tsis txhob cuam tshuam rau qhov kub thiab txias.
3. Kev sib piv ntawm Cov Ntoo Hluav Taws Xob thiab lwm yam khoom siv
Piv nrog rau ntau lwm yam khoom siv hluavtaws, hluav taws xob ntoo muaj kev nyab xeeb dua. Piv txwv li, piv rau tej yam yas, hluav taws xob ntoo tsis muaj tshuaj lom neeg xws li plasticizers thiab stabilizers rau tib neeg lub cev. Tsis tas li ntawd, cov hluav taws kub tsis kam ntawm cov ntoo hluav taws xob zoo dua li ntau cov yas, thiab nws tuaj yeem tswj tau lub cev zoo thiab tshuaj lom neeg ntawm qhov kub thiab txias. Yog li ntawd, nyob rau hauv ntau qhov xwm txheej, kev xaiv siv cov khoom siv hluav taws xob yog qhov kev xaiv zoo dua.
4. Cov lus xaus
Hauv cov ntsiab lus, hluav taws xob ntoo tsis muaj tshuaj lom nyob rau hauv kev siv ib txwm siv, tab sis nws yuav tsim tau qee yam tshuaj lom nyob rau hauv qhov kub thiab txias. Thaum siv cov khoom siv hluav taws xob ntoo, nws yog ib qho tseem ceeb kom tsis txhob muaj qhov kub thiab txias thiab ua kom huv. Piv nrog rau lwm cov khoom siv hluavtaws, hluav taws xob ntoo muaj kev nyab xeeb dua.
