Daim ntawv thov ntawm Sodium Carboxymethyl Cellulose hauv Cigarettes thiab Vuam Rods

Sodium carboxymethyl cellulose (CMC) muaj ntau hom kev siv hauv kev lag luam tshaj nws cov kev siv ntau dua. Txawm hais tias tsis paub dav dav, CMC nrhiav kev siv hluav taws xob hauv qee qhov kev siv niche xws li luam yeeb thiab vuam pas nrig:

1. Cov luam yeeb:
   • Adhesive: CMC qee zaum siv los ua cov nplaum hauv kev tsim cov luam yeeb. Nws tuaj yeem siv rau hauv daim ntawv qhwv los pab muab cov ntawv luam yeeb thiab ua kom muaj kev ncaj ncees ntawm cov qauv luam yeeb. CMC cov khoom nplaum ua kom ntseeg tau tias cov luam yeeb tseem ntim nruj thiab tiv thaiv kom tsis txhob haus luam yeeb poob los yog tshem tawm thaum tuav thiab haus luam yeeb.
   • Burn Rate Modifier: CMC kuj tuaj yeem muab ntxiv rau hauv daim ntawv luam yeeb ua tus hloov pauv tus nqi hlawv. Los ntawm kev kho qhov concentration ntawm CMC nyob rau hauv daim ntawv, manufacturers tuaj yeem tswj tus nqi ntawm cov luam yeeb kub. Qhov no tuaj yeem cuam tshuam rau yam xws li kev haus luam yeeb, kev tso tawm tsw, thiab kev tsim cov tshauv. CMC pab tswj tus cwj pwm combustion ntawm cov luam yeeb, pab txhawb kev haus luam yeeb ntau dua thiab txaus siab rau cov neeg siv khoom.
2. Vuam Rods:
   • Flux Binder: Hauv kev tsim cov pas nrig vuam, CMC yog siv los ua cov khoom siv hluav taws xob hauv coated electrodes. Flux yog ib yam khoom siv rau vuam rods los pab cov txheej txheem vuam los ntawm kev txhawb nqa cov txheej txheem tiv thaiv slag thiab txhim kho qhov zoo ntawm cov vuam. CMC ua raws li ib tug binder rau lub flux Cheebtsam, pab mus rau adheres rau ntawm qhov chaw ntawm vuam pas nrig tub ntxhais. Qhov no ua kom muaj kev sib faib ntawm cov ntaub ntawv flux thiab txhim khu kev ruaj ntseg thiab kev ua tau zoo ntawm txheej thaum ua haujlwm vuam.
   • Arc Stabilizer: CMC kuj tuaj yeem ua tus arc stabilizer hauv vuam rods. Thaum lub sij hawm vuam, lub arc generated ntawm lub electrode thiab lub workpiece yuav ua rau instability los yog erratic tus cwj pwm, ua rau tsis zoo weld zoo thiab tswj. CMC-muaj cov coatings ntawm vuam pas nrig pab stabilize lub arc los ntawm muab ib tug zoo ib yam thiab tswj hluav taws xob conductivity. Qhov no ua rau smoother arc ignition, zoo arc tswj, thiab txhim kho weld nkag mus thiab deposition nqi.

Hauv ob daim ntawv thov, sodium carboxymethyl cellulose (CMC) muaj cov khoom tshwj xeeb uas pab txhawb kev ua haujlwm thiab kev ua haujlwm ntawm cov khoom kawg. Nws cov nplaum, hlawv tus nqi hloov pauv, flux khi, thiab arc stabilizing zog ua rau nws muaj txiaj ntsig zoo ntxiv hauv kev tsim cov luam yeeb thiab vuam pas nrig, txhim kho lawv qhov zoo, sib xws, thiab siv tau.
