Vim nws cov khoom tshwj xeeb, xanthan cov pos hniav tau siv dav hauv ntau lub teb, suav nrog zaub mov, roj av, tshuaj, thiab tshuaj txhua hnub. Nws qib siab ntawm kev lag luam thiab kev siv ntau yam tshaj li lwm yam microbial polysaccharide.
1. Kev siv khoom noj khoom haus: Xanthan cov pos hniav yog ntxiv rau ntau yam khoom noj khoom haus raws li lub stabilizer, emulsifier, suspending agent, thickener, thiab kev pab cuam. Xanthan cov pos hniav tuaj yeem tswj cov rheology, qauv, tsw, thiab cov tsos ntawm cov khoom, thaum nws cov pseudoplasticity ua kom lub saj zoo. Yog li ntawd, nws yog dav siv nyob rau hauv cov khaub ncaws hnav khaub ncaws, qhob cij, khoom noj siv mis, khoom noj khov, dej haus, condiments, brewing, confectionery, pastries, kua zaub, thiab cov kaus poom zaub mov. Nyob rau hauv xyoo tas los no, cov neeg nyob rau hauv ntau lub teb chaws tsim muaj kev txhawj xeeb txog cov calorie ntau ntau ntawm cov zaub mov ua rau hnyav nce. Xanthan cov pos hniav, vim nws tsis tuaj yeem ncaj qha degraded los ntawm tib neeg lub cev, alleviates qhov kev txhawj xeeb no. Tsis tas li ntawd, raws li tsab ntawv tshaj tawm xyoo 1985 los ntawm Nyij Pooj, qhov kev sib piv ntawm kaum ib cov khoom noj ntxiv tau pom tias xanthan cov pos hniav yog cov tshuaj tiv thaiv kab mob zoo tshaj plaws.
2. Hauv kev lag luam tshuaj lom neeg niaj hnub: Xanthan gum molecules muaj ntau pawg hydrophilic, ua rau nws yog ib qho zoo heev surfactant nrog antioxidant thiab anti-aging zog. Yog li ntawd, nws yog ib qho tseem ceeb muaj nyob rau hauv yuav luag tag nrho cov high - cov tshuaj pleev ib ce kawg. Tsis tas li ntawd, xanthan cov pos hniav tuaj yeem siv los ua cov thickener thiab stabilizer hauv cov tshuaj txhuam hniav, txo cov hniav hnav.
3. Hauv kev kho mob: Xanthan cov pos hniav yog ib qho nrhiav tau zoo heev - tom qab kev ua haujlwm hauv microcapsule tshuab xa tshuaj, ua lub luag haujlwm tseem ceeb hauv kev tswj cov tshuaj tso tawm. Vim nws muaj zog hydrophilicity thiab dej-cov khoom tuav, nws kuj muaj ntau yam kev kho mob tshwj xeeb, xws li tsim cov yeeb yaj kiab dej ntom ntom kom tiv thaiv kab mob ntawm daim tawv nqaij thiab txo qis nqhis dej tom qab siv hluav taws xob. Tsis tas li ntawd, Li Xin thiab Xu Lei tau sau tias xanthan cov pos hniav nws tus kheej muaj qhov cuam tshuam loj rau kev tiv thaiv kab mob hauv nas.
4. Kev lag luam thiab kev ua liaj ua teb: Hauv kev lag luam roj av, vim nws cov pseudoplasticity muaj zog, qis -cov pos hniav xanthan (0.5%) aqueous tov tuaj yeem tswj cov viscosity ntawm drilling kua thiab tswj nws cov khoom rheological. Yog li ntawd, cov viscosity tsawg heev nyob rau hauv siab -ceev rotating laum me ntsis cheeb tsam, txuag zog; thaum tuav cov viscosity siab nyob rau hauv qhov chaw nyob ruaj ruaj borehole, yog li tiv thaiv wellbore vau. Tsis tas li ntawd, vim nws cov ntsev zoo heev thiab kub tsis kam, nws tau siv dav hauv kev drilling hauv qhov chaw tshwj xeeb xws li cov chaw hauv hiav txwv thiab siab - thaj chaw ntsev, thiab tuaj yeem siv los ua cov roj hloov pauv kom txo cov roj tuag thiab txhim kho cov roj rov qab.
