Qhov chaw ntawm formaldehyde hauv cov hlau tuaj yeem ua txheej
Nov 07, 2020
Thaum tam sim no, cov tshuaj pleev plhuav dav siv cov tshuaj pleev xim av tsuas yog epoxy phenolic resin, epoxy amino txheej, epoxy polyamide cob, organic sol txheej, vinyl txheej, polyester txheej, acrylic txheej, epoxy ester txheej thiab li ntawd. Vim tias nws cov tshuaj lom neeg yav tom ntej corrosion, roj tsis kam thiab dej tsis kam, epoxy resin feem ntau yog siv los ua cov khoom siv tseem ceeb ntawm cov zaub mov tinplate sab hauv txheej. Raws li ib qho ntawm kev pib ua kom rov qab ntawm epoxy resin txheej, formaldehyde tuaj yeem ua kom cov khoom noj tsis huv hauv cov kaus poom hlau feem ntau los ntawm cov txheej txheem kev ua nrog.
Qhov ua mob loj ntawm formaldehyde yog qhov voos ua kom tawv nqaij thiab hnoos qeev. Kev siv sij hawm ntev ntev yuav ua rau muaj kev pauv hloov noob thiab ua rau muaj kev pheej hmoo mob qog nqaij hlav ntshav xws li mob cancer ntshav thiab lymphatic mob cancer. Nws tau muab teev cia ua hom carcinogen (pawg 1) los ntawm International Cancer Research Institute IARC.
Kev txiav txim siab ntawm formaldehyde hauv cov hlau tuaj yeem ua txheej
GB / t5009.69-2008" tshuaj ntsuam txoj kev ntawm tus txheej txheem huv rau epoxy phenolic txheej nyob rau sab hauv phab ntsa ntawm cov khoom noj khoom haus cov zaub mov" yog ncaj qha sib npaug rau cov ntsiab lus formaldehyde, thiab lub hauv paus ntsiab lus ntawm qhov ntau ntau qhov sib piv nrog tus qauv yog siv los txiav txim siab dawb formaldehyde nyob rau sab hauv phab ntsa txheej ntawm cov zaub mov kaus poom.
SMQ lub koom haum kev soj ntsuam zaub mov yog ib txwm npaj rau koj!
Xyoo tsis ntev los no, SMQ lub koom haum kuaj khoom noj khoom haus tau cog lus rau txoj kev tshawb fawb ntawm cov zaub mov ntim khoom kuaj kev nyab xeeb, thiab tau tsim kev tshuaj ntsuam xyuas kev nplua nuj, thiab tau ua cov khoom lag luam sib cuag cov khoom ntim ntawm cov yas hwj, cov kas tham, microwave tableware, acrylic ntsig txog cov khoom noj sib cuag , thermoplastic elastomer, cov zaub mov ntim ntawv thiab cov kaus poom hlau, cov zaub mov sab hauv phab ntsa txheej thiab lwm yam Kev pov hwm saib xyuas cov khoom. Los ntawm kev siv roj chromatography-huab hwm coj spectrometry, kua nyeem kua nyeem-huab hwm coj spectrometry thiab PCR thev naus laus zis, bisphenol A, plasticizer, solvent residue, dawb formaldehyde, microorganism thiab lwm yam khoom muaj feem rau hauv cov khoom siv hu zaub mov tuaj yeem nrhiav tau sai.
