Daim ntawv thov
Kev lag luam zaub mov thiab dej haus
Hauv cov khoom noj thiab dej haus, zoo heev - qib lactic acid yog dav siv. Nws tuaj yeem siv los ua acidulant hauv ntau yam khoom. Piv txwv li, nyob rau hauv cov zaub xam lav hnav khaub ncaws, nws muab ib tug tangy tsw thiab pab nyob rau hauv kev kho cov pH los txhim kho lub stability thiab txee - lub neej ntawm cov khoom. Lub siab purity ua kom ntseeg tau tias nws tsis qhia tawm - flavors los yog cov kab mob uas yuav cuam tshuam rau saj thiab zoo ntawm cov zaub mov.
Hauv kev tsim cov khoom noj fermented xws li hnyuv ntxwm thiab pickles, lactic acid ntawm qib zoo tuaj yeem ua rau cov txheej txheem fermentation. Nws pab tsim kom muaj ib puag ncig acidic uas inhibits kev loj hlob ntawm kev lwj - ua rau cov kab mob thiab tseem cuam tshuam cov yam ntxwv tsw rau cov khoom.
Kev Lag Luam Textile
Hauv textile xov, zoo heev - qib lactic acid tuaj yeem siv rau kev kho ntaub. Nws tuaj yeem ua raws li pH regulator thaum lub sij hawm dyeing txheej txheem. Piv txwv li, nws pab teeb tsa qhov tseeb pH rau cov kua qaub dyes, uas yog siv los ua cov ntaub plaub thiab cov ntaub lo lo ntxhuav. Kev siv cov lactic acid tuaj yeem txhim kho cov xim ceev thiab tag nrho qhov zoo ntawm cov ntaub ntawv dyed.
Lactic acid kuj tuaj yeem siv los ua cov ntaub mos muag. Thaum siv rau qee yam ntuj fibers xws li paj rwb, nws tuaj yeem ua rau qee qhov fiber ntau - stiffening Cheebtsam, tawm hauv cov ntaub nrog softer xav thiab zoo dua drape.
Biodegradable Plastics thiab Polymers
Hauv kev tsim cov yas biodegradable, zoo heev - qib lactic acid yog ib qho tseem ceeb. Nws tuaj yeem ua polymerized los ua polylactic acid (PLA) - raws li cov ntaub ntawv. Txawm hais tias purity yuav tsum tau rau PLA ntau lawm yuav txawv, zoo heev - qib lactic acid feem ntau yuav siv tau nyob rau hauv thawj zaug polymerization cov kauj ruam. Cov PLA - raws li cov yas no muaj cov ntawv thov hauv ntim, cov khoom siv pov tseg, thiab lwm yam khoom uas biodegradability yog ib qho khoom tsim nyog.
