Yuav ua li cas yog ib tug surfactant, thiab yuav ua li cas lawv muaj kev cuam tshuam cov ib puag ncig?

Dej yog qhov feem ntau ntawm cov ntiaj chaw universal kuab. Mus ntxov lig tej yam khoom uas nkag mus rau hauv kev sib cuag nrog nws, nws yog raug mus rau ib tug hydrolysis cov tshuaj tiv thaiv thiab decomposes.

Txawm li cas los, nyob rau hauv tej rooj plaub, txoj kev no yuav tsum tau ceev, tsis tos rau nws dhau ntawm ib tug tej yam ntuj tso tus nqi. Rau lub hom phiaj no surfactants.

Yuav ua li cas yog ib tug surfactant? Qhov no tshuaj tebchaw uas ua rau kom cov dej ntws thiab txhim kho nws muaj peev xwm ntub ntau cev lub cev. Efficiency ntawm tus txheej txheem no tsis pub nto nro - ib tug nyias zaj duab xis tsim los ntawm cov molecules ntawm cov kua, nkauj nraug nws los ntawm qhov lwm tus gaseous medium. Cov txheej no yog heev ruaj, nws tsim ib tug teeb meem mus rau lub allergic ntawm cov dej mus rau cov khoom uas koj xav tau rau ib co yog vim li cas rau ntub txaus nws molecules.

Lub ntsiab yog vim li cas yog vim li cas tib neeg yuav los ntub ib tug ntau yam ntawm tej yam khoom - ib tug muaj siab mus luaj lawv los ntawm cov av, uas yog ntxuav los yog ntxuav tawm. Xab npum - qhov tseem ceeb tshaj thiab hiob surfactant, los ntawm cov uas tib neeg accomplishes no, tab sis lub achievements ntawm niaj hnub Science News for KIDS pom tau hais tias xws li ib tug surfactant yog tsis muaj ntev feem ntau txhais tau tias zoo. Dua li ntawm qhov loj loj tus naj npawb ntawm ua thiab noj tshuaj ntxuav tes, khaub ncaws thiab ntxuav tais diav nws yog tsis tshua muaj siv niaj hnub no. Txij thaum lig forties ntawm lub XX xyoo pua, tshiab detergents uas muaj ib tug tiag tiag miraculous hwj chim, tshaaj rau cov kev puas tsuaj ntawm tus nto nro.

Classification surfactants nyob rau hauv lawv cov tshuaj nyob tus yeees, molecular qauv thiab qhov xwm ntawm tus raug muaj xws li:

- Tsis-ionic surfactants.

- amphoteric surfactants.

- cationic surfactants.

- Anionic surfactants.

Rau tag nrho nws cov tswv yim thiab nyiaj txiag nqi hluav taws xob ntawm qhov chaw-active tshuaj uas ua los ntawm niaj hnub tshuaj lag luam nyob rau hauv ib tug tiag tiag Titanic nqi sawv cev rau ib tug tej yam kev hem thawj rau lub ntiaj chaw ecology. Txawm hais tias muaj yog ib tug tshuaj uas yog phua rau hauv carbohydrates tom qab siv. Peb yuav hais tias qhov no surfactant, tsim nyob rau hauv lub hauv paus ntawm alkylpolyglucosides, kev ruaj ntseg rau cov ib puag ncig.

Main feem ua raws li detergents thiab ntxuav cov hmoov yog resistant rau degradation thiab khaws lawv lub zog tshaj ib tug ntev lub sij hawm. Tau mus rau hauv lub pas dej thiab tej dej hiav txwv, lawv thiaj li yuav thiaj li muaj feem xyuam rau lub ntsiab thaj chaw ntawm cov kua ntawm cov ntiaj chaw, nws yuav tuag taus. Niaj hnub no (vim hais tias ntawm lub nplua mais ntawm pov tseg xab npum) rau hauv cov dej, nrog rau haus dej haus cawv, los ntawm cov av tau tawv ncauj hais ntawm hnyav hlau, cov teeb meem los ntawm lub cev. Cov teeb meem inclusions yuav tsis tau thiaj li nquag yaj nyob rau hauv dej, ces mus rau hauv nws los ntawm cov av, yog hais tias nws twb tsis tam sim no surfactants nyob rau hauv threatening ntau.

Nws yuav zoo li, dab tsi yog qhov teeb meem no? Nws yog ib tsab rau ban zus tau tej cov detergents, tsuas yog cov neeg uas yog raws li nyob rau hauv kev ruaj ntseg alkylpolyglucosides. Tab sis tsis yog txhua txhua thiaj li yooj yim. Qhov tseeb hais tias xws li ib tug surfactant yog kim heev, thiab muaj nws cov detergents tsis txhua leej txhua tus muaj peev xwm them taus. Qhov tseeb hais tias lub txim ntawm kev mob-xam tau tias yog cov ntaub ntawv ntawm cov tshuaj yuav tsum tau tswj, producers thiab tau txais kev pab tsis tshua xav hais tias.
