APEO yog dab tsi?
APEO yog cov ntawv luv ntawm Alkylphenol Ethoxylates. Nws yog tsim los ntawm condensation cov tshuaj tiv thaiv ntawm alkylphenol (AP) thiab ethylene oxide (EO), xws li nonylphenol polyoxyethylene ether (NPEO) thiab octylphenol polyoxyethylene ether (OPEO), thiab lwm yam.
Kev phom sij ntawm APEO
1. Toxicity
APEO muaj mob toxicity thiab dej toxicity. Nws muaj ze-muaj zog toxicity rau ntses.
2.Irritation
Kev khaus ntawm APEO rau tib neeg lub qhov muag thiab tawv nqaij thiab kev puas tsuaj ntawm APEO rau mucosa yog kaum tawm zaus ntau dua li qee qhov nonionic surfactants, xws li alkyl phenol polyglycosides.
3.Poor biodegradability
APEO tsis yog biodegradable, nws tus nqi biodegradation yog 0 ~ 9% nkaus xwb. Ntawm ib sab, APEO yog ib qho yooj yim mus sau nyob rau hauv cov kab mob lom. Yog hais tias nws tshaj tus nqi tseem ceeb pathogenic, nws yuav ua rau toxication. Ntawm qhov tod tes, alkylphenol, cov khoom degradation ntawm APEO, yog ib hom estrogen zoo li cov tshuaj hormones, uas yuav cuam tshuam endocrine thiab tuaj yeem ua rau muaj kev loj hlob ntawm tib neeg cov tshuaj estrogen rhiab rau cov qog nqaij hlav cancer mis.
4.Environmental estrogen teeb meem
APEO muaj cov nyhuv zoo sib xws rau cov tshuaj estrogen. Nws yog ib yam tshuaj uas tuaj yeem ua rau lub cev tsis muaj tshuaj hormone secretion. Nws yuav ua rau txo qis ntawm cov phev suav thiab qhov txawv txav ntawm cov kab mob hauv lub cev.
Kev Siv Feem Ntau ntawm APEO hauv Textile
APEO muaj cov haujlwm zoo heev ntawm kev ntub dej, nkag mus, dispersing thiab emulsifying, thiab lwm yam, uas feem ntau siv rau hauv cov khoom siv textile raws li hauv qab no:
Spinning Roj
Pretreatment Auxiliaries: np. Detergent, Desizing Agent, Degreasing Agent, Scouring Agent, Wetting Agent thiab Penetrating Agent, thiab lwm yam.
Dyeing and Printing Auxiliaries: eg. High Temperature Leveling Agent, Dispersing Agent, Defoaming Agent thiab Emulsifying Agent, thiab lwm yam.
Tus neeg ua haujlwm tiav: np. Softener thiab Water-proof Agent, thiab lwm yam.
Tawv Auxiliaries: eg. Fat Liquor, Coating Agent, Degreasant, Penetrant thiab Dispersing Agent, thiab lwm yam.
Yuav daws qhov teeb meem dhau ntawm APEO li cas?
APEO yog hydrophilic. Kev ntxuav dej tuaj yeem txo qhov seem ntawm APEO zoo heev. Nws yog qhov zoo dua los siv 70% ethanol aqueous tov rau so thiab ntxuav (qhov flammability ntawm ethanol yuav tsum tau muab sau tseg thaum ua haujlwm).
Nws yog xav kom sivdyeingthiab ua tiav auxiliaries tsis muaj APEO, uas yog los tswj ntawm qhov chaw. Kev ntxhua khaub ncaws ntau yuav tsis tsuas yog nce nqi ntau lawm thiab ua rau muaj kuab paug ib puag ncig, tab sis kuj yuav ua rau qee yam kev puas tsuaj rau peb cov khoom.
Thaum cov koom haum koom nrog, cov koom haum pabcuam tuaj yeem txiav txim siab siv rosin polyoxyethylene ester, fatty cawv polyoxyethylene ether, alkyl polyglycosides, n-alkyl gluconamide thiab non-ionic Gemini surfactants, thiab lwm yam los hloov APEO.
