Ⅲ. Kev Npaj Rau Daim Ntawv Thov

Nrog rau kev txhim kho tas mus li ntawm cov qauv kev tiv thaiv ib puag ncig thoob ntiaj teb, kev txhim kho ntawm cov kab ke kev noj qab haus huv pej xeem thiab kev txhim kho ntawm kev tsim khoom lag luam, kev thov ua lag luam rau kev ua haujlwm siab, tsis muaj tshuaj lom thiab tsis muaj kuab paug rau ib puag ncig thiab cov khoom siv tiv thaiv xeb tau loj hlob tas li. Raws li cov khoom lag luam quaternary ammonium ntsuab thiab ua haujlwm tau zoo,DDACmuaj kev cia siab rau kev siv lag luam dav heev.

Hauv kev kho dej hauv kev lag luam, DDAC ua haujlwm ua tus neeg sawv cev tseem ceeb rau kev tua kab mob thiab algaecide rau cov dej ncig, kev kho dej rov qab osmosis thiab cov dej rov ua dua tshiab hauv cov roj av. DDAC tuaj yeem ua kom dej huv, tiv thaiv kev loj hlob ntawm cov kab mob me me, tiv thaiv cov khoom siv hauv cov kav dej lag luam, txo cov khoom siv xeb thiab cov nqi khiav lag luam thiab kev saib xyuas, thiab daim teb no tau dhau los ua kev lag luam tseem ceeb ntawm DDAC.

Hauv kev tua kab mob rau pej xeem, DDAC yog qhov tsim nyog rau kev tua kab mob txhua hnub ntawm cov chaw txias, cov tshuab cua txias hauv nruab nrab, cov tsheb thauj neeg pej xeem, cov khoom siv kho mob thiab cov chaw ua zaub mov. DDAC muaj kev hloov pauv zoo heev rau qhov kub qis, thiab nws cov kev ua haujlwm tua kab mob tseem ruaj khov hauv cov xwm txheej tua kab mob atomized kub qis, ua tau raws li qhov xav tau ntawm kev tiv thaiv kev noj qab haus huv pej xeem.

Hauv kev ua liaj ua teb, kev cog ntoo thiab cov ntaub ntawv siv hauv tsev, DDAC siv tau rau kev kho cov noob qoob loo ua ntej kom tiv thaiv cov kab mob fungal uas kis los ntawm av thiab txhim kho cov qoob loo germination thiab kev ciaj sia. Lub caij no,DDACtuaj yeem hloov cov neeg sawv cev ib txwm muaj kuab paug siab ua cov neeg sawv cev tiv thaiv xeb thiab pwm rau ntoo, xyoob cov ntaub ntawv thiab cov txheej txheem, txhawb kev txhim kho ntsuab ntawm kev lag luam khoom siv hauv tsev.

Hauv kev lag luam textile sib dua, vam khom cov khoom mos, tiv thaiv hluav taws xob thiab tiv thaiv kab npauj npaim, DDAC siv rau hauv kev ua tiav textile kom txhim kho kev xav ntawm cov ntaub, txo qhov nqus hluav taws xob thiab kev puas tsuaj ntawm kab npauj npaim, thiab txhim kho cov khoom zoo.

Hauv kev ua liaj ua teb aquaculture, DDAC tuaj yeem tua kab mob qe ntses thiab cov dej aquaculture, tiv thaiv tau cov kab mob hauv dej xws li saprolegniasis thiab ua kom lub chaw ua liaj ua teb aquaculture ruaj khov. Tam sim no, ntau yam lag luam tau muab cov kev cai siab dua rau kev nyab xeeb, kev tiv thaiv ib puag ncig thiab cov txiaj ntsig mus sij hawm ntev ntawm cov khoom tua kab mob, thiab cov tshuaj lom neeg thiab cov tshuaj seem ntau dhau maj mam tshem tawm.

Cov txiaj ntsig ntawm DDAC xws li tsis muaj tshuaj lom, kev tiv thaiv ib puag ncig, kev ua haujlwm zoo thiab cov lus qhia hloov pauv tau pom tseeb zuj zus. 80% cov ntsiab lus DDAC ua tau raws li qhov xav tau ntawm kev siv ntau ntawm kev lag luam, thiab 50% cov ntsiab lus DDAC hloov kho rau cov xwm txheej pej xeem thiab cov haujlwm me. Lub kaw lus dual-specification ntawm DDAC npog tag nrho cov kev xav tau ntawm kev ua lag luam. Yav tom ntej, nrog rau kev txhim kho tas mus li ntawm lub zog tshiab, cov ntaub ntawv tshiab thiab kev lag luam kev noj qab haus huv pej xeem, cov xwm txheej ntawm daim ntawv thov ntawm DDAC yuav raug nthuav dav ntxiv, thiab kev nkag mus rau hauv kev ua lag luam yuav txuas ntxiv mus ntxiv.

Ⅳ. Xaus lus

Xaus lus,Didecyl Dimethyl Ammonium Chloride (DDAC)sawv cev rau lub hauv paus tseem ceeb ntawm cov thev naus laus zis niaj hnub no. Los ntawm nws ob qho kev ntsuas tus qauv (80% thiab 50%), DDAC muab kev ywj pheej rau ob qho tib si kev tsim cov tshuaj hnyav thiab kev ntxuav ncaj qha. Lub tshuab tshwj xeeb ntawm DDAC ua kom muaj kev tshem tawm cov kab mob tsis muaj kev cia siab rau cov tshuaj corrosive. Raws li cov qauv kev noj qab haus huv pej xeem txuas ntxiv nce thoob ntiaj teb, lub luag haujlwm ntawm DDAC tsuas yog yuav dhau los ua qhov tseem ceeb hauv kev nyab xeeb zaub mov, kev kho dej, thiab kev tu cev huv. Cov chaw tsim khoom thiab cov kws tshaj lij tu cev huv si txuas ntxiv tshawb pom cov ntawv thov tshiab rau DDAC, ua kom nws txoj haujlwm ua cov khoom muaj nqis tseem ceeb rau yav tom ntej.
