Daim ntawv thov kev kho mob thiab tus kheej
Chlorocresol muaj cov tshuaj tua kab mob thiab tshuaj tua kab mob thiab siv los ua cov tshuaj tua kab mob thiab tshuaj tua kab mob hauv cov tshuaj thiab cov khoom tu tus kheej. Hauv cov tshuaj pleev ib ce xws li tshuaj pleev, tshuaj pleev, tshuaj ntxuav tes thiab tshuaj tua kab mob, nws tiv thaiv cov khoom los ntawm cov kab mob microbial thaum siv. Nws kuj yog siv rau hauv cov tshuaj tua kab mob, nrog rau cov kev daws teeb meem rau kev kho cov kab mob ntawm daim tawv nqaij thiab kub hnyiab me. Nyob rau hauv European Union, chlorocresol tau tso cai ua ib qho tshuaj khaws cia hauv cov khoom siv tshuaj pleev ib ce raws li Kev Cai Tshuaj Txhuam Hniav nrog qhov siab tshaj plaws ntawm 0.2 feem pua, thiab cov kev txwv zoo sib xws siv hauv lwm lub khw muag khoom; formulators yuav tsum tau txheeb xyuas qhov kev txwv rau txhua yam khoom tiav.
Kev ua liaj ua teb
Hauv kev ua liaj ua teb, chlorocresol yog cov khoom siv raw rau tshuaj tua kab thiab tshuaj tua kab. Nws cov qauv phenolic pab txhawb cov tshuaj tua kab muaj zog uas pab tswj qee cov kab tsuag qoob loo, thiab nws yog siv rau hauv kev sib xyaw ntawm cov tshuaj herbicides uas txwv cov nroj tsuag kev loj hlob thiab tiv thaiv qoob loo. Raws li nrog rau tag nrho cov tshuaj ua liaj ua teb, cov khoom tiav yuav tsum ua kom tau raws li kev tso npe thiab cov khoom seem ntawm cov khw uas lawv tau thov.
Kev lag luam tshuaj thiab lwm yam kev lag luam siv
Hauv kev lag luam tshuaj, chlorocresol yog cov khoom siv raw hauv cov organic synthesis. Nws yog siv los tsim cov tshuaj tsw qab xws li cov tshuaj tsw qab thiab cov tshuaj tsw qab, thiab nws yog siv rau hauv kev tsim cov dyes thiab pigments rau xim thiab staining. Tshaj li kev sib txuas, chlorocresol yog siv los ua cov khoom siv ntoo los tiv thaiv ntoo tiv thaiv kab mob thiab kab puas tsuaj, thiab ua cov tshuaj tua kab mob hauv cov roj hmab sib txuas kom txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv roj hmab los ntawm kev ua kom oxidative degradation.
Specifications thiab kev txiav txim siab zoo
Kev lag luam thiab tshuaj qib ntawm chlorocresol yog tus cwj pwm los ntawm kev soj ntsuam, cov ntsiab lus melting ntau, poob ntawm ziab, residue ntawm ignition thiab lwm yam impurities.
