Cawv yog ib qho tseem ceeb heev cov ntaub ntawv raw cov ntaub ntawv siv dav hauv ntau yam xws li kev tsim khoom, kev kho mob thiab kev lag luam tshuaj, thiab lub neej txhua hnub. Lawv cov kev siv tseem ceeb yog categorized raws li hauv qab no:
1. Kev lag luam thiab tshuaj lom neeg txhua hnub
Cov kuab tshuaj: Cov cawv qis dua yog cov kuab tshuaj organic ntau tshaj plaws hauv kev tsim khoom. Lawv tuaj yeem yaj cov organic xws li coatings, resins, thiab dyes. Lawv kuj tuaj yeem ua ke nrog surfactants hauv cov khoom siv tshuaj niaj hnub los txhim kho cov emulsification, nkag mus, thiab degreasing peev xwm ntawm cov tshuaj ntxuav tes thiab cov khoom tu tawv nqaij. Piv txwv li, methanol yog siv nyob rau hauv cov xim thiab roj hmab industries; ethanol yog siv nyob rau hauv cov tshuaj tsw qab thiab aromatherapy khoom; propylene glycol yog cov kuab tshuaj nquag siv hauv cov tshuaj pleev ib ce, da dej gels, thiab cov khoom tu tawv nqaij; isopropanol feem ntau hloov ethanol hauv kev lag luam tu vim nws cov nqi qis dua thiab kev nyab xeeb zoo dua.
Antifreeze/Freeze Agents: Ethylene glycol muaj qhov chaw khov tsis tshua muaj khov thiab yog lub hauv paus tiv thaiv kev tiv thaiv kab mob hauv tsheb tiv thaiv kab mob thiab lub tshuab ua kom lub tshuab ntxhua khaub ncaws. Cov cawv qis kuj tuaj yeem siv ncaj qha los ua cov tshuaj tiv thaiv kab mob.
Chemical Raw Materials: Lawv tuaj yeem siv rau hauv kev sib txuas ntawm ntau yam khoom siv tshuaj xws li roj hmab, detergents, plastics, thiab coatings; Cov cawv ntau dua tuaj yeem siv ua defoamers thiab reservoir evaporation inhibitors; methanol kuj yog ib qho tseem ceeb ntawm cov organic synthesis nruab nrab hauv cov dye thiab resin industries.
2. Kev Kho Mob thiab Pharmaceutical Fields
Kev tua kab mob thiab ua kom tsis muaj menyuam: 70%-75% ethanol thiab isopropanol feem ntau yog siv nruab nrab- cov tshuaj tua kab mob, muaj peev xwm tua cov kab mob vegetative thiab cov kab mob lipophilic feem ntau. Lawv tau siv dav rau kev tua kab mob ntawm daim tawv nqaij, so cov cuab yeej kho mob, thiab kev tu cev ntawm tes . 95% high-concentration ethanol feem ntau yog siv rau lub cev qhuav dej thiab kho cov ntaub so ntswg.
Pharmaceutical Excipients: Ethanol yog ib qho tshuaj hnyav uas nquag siv, txhim kho cov tshuaj solubility thiab ncua lub neej txee. Nws yog feem ntau siv rau hauv kev npaj ntawm tinctures, liniments, thiab lwm yam tshuaj sab nraud, thiab tseem tuaj yeem siv los ua cov khoom siv hauv qee cov tshuaj hauv qhov ncauj los txhim kho kev nqus tshuaj.
Kev Kho Mob Tshwj Xeeb: Nitroglycerin (glyceryl trinitrate) tuaj yeem nthuav cov hlab ntsha thiab yog ib hom tshuaj siv los kho angina pectoris thiab biliary colic. Ethanol kuj tseem siv tau los ua tshuaj tua kab mob rau methanol lom, inhibiting methanol metabolism thiab txo toxicity.
3. Daily Life and Energy Fields
Khoom noj khoom haus thiab dej haus: Ethanol yog ib qho tseem ceeb ntawm cov dej cawv. Ethanol ua los ntawm cov nplej fermentation tuaj yeem siv ncaj qha rau hauv kev tsim cov dej cawv.
Roj: Ob leeg methanol thiab ethanol tuaj yeem siv los ua roj. Ethanol roj av yog ib puag ncig tus phooj ywg roj ua los ntawm kev ntxiv ethanol rau roj av. Ethanol kuj tuaj yeem siv ncaj qha los ua cov roj ua lag luam.
Mineral Processing: Hauv kev ua cov ntxhia, cawv tsis yog siv los ua frothers xwb tab sis kuj tseem yog cov ntaub ntawv tseem ceeb rau kev sib txuas ntawm lwm cov ntxhia ua cov tshuaj reagents.
