Ingcaciso yeMveliso

Uhlobo lwekhemikhali

I-Diethanolamine sisiseko se-organic esisetyenziswe njenge-emulsifying and dispersing agent. Ingasetyenziswa njenge-basic buffer, ene-pH efanelekileyo malunga ne-pH 9, ukuba ixutywe ne-HCl okanye enye i-asidi. Ezinye iindlela zokusetyenziswa ziquka: "ukukhuhla" iigesi, njenge-chemical intermediate, njenge-humectant okanye i-softening agent.

Izicelo

I-Diethanolamine efana ne-triethanolamine isetyenziswa njenge-surfactant. Ikwanako nokuba yi-corrosion inhibitor ngokusebenzisa i-chemisorption.

Ukukhuhla iigesi njengoko kubonisiwe phantsi kwe-ethanolamine. I-Diethanolamine ingasetyenziswa neegesi eziqhekekayo kunye neegesi zamalahle okanye zeoyile eziqulethe i-carbonyl sulfide eza kusabela kwi-monoethanolamine. Njengeekhemikhali zerabha eziphakathi. Ekwenzeni iiarhente ezisebenzayo kumphezulu ezisetyenziswa kwiingcali zelaphu, iiherbicides, ii-petroleum demulsifiers. Njenge-emulsifier kunye ne-dispersing agent kwiikhemikhali ezahlukeneyo zezolimo, izinto zokuthambisa, kunye namayeza. Ekwenzeni izithambisi zoshishino lwelaphu. Njenge-humectant kunye ne-softening agent. Kwi-organic syntheses.

I-Diethanolamine isetyenziswa ekuveliseni izinto ezisebenzayo kumphezulu kunye nezinto zokuthambisa kwishishini lempahla; njengento ephakathi kweekhemikhali zerabha; njenge-emulsifier; njenge-humectant kunye ne-arhente yokuthambisa; njengesepha kwiipeyinti, ii-shampoo, kunye nezinye izinto zokucoca; kwaye njengenxalenye kwiiresini kunye neeplastiki.

ukhuseleko

Xa uphatha le mveliso, nceda ulandele iingcebiso nolwazi olunikiweyo kwiphepha ledatha yokhuseleko kwaye ulandele amanyathelo okhuseleko kunye nococeko kwindawo yokusebenza afanelekileyo okuphatha iikhemikhali.

 

Phawula

Idatha equlethwe kule ncwadi isekelwe kulwazi lwethu lwangoku namava. Ngenxa yezinto ezininzi ezinokuchaphazela ukucutshungulwa nokusetyenziswa kwemveliso yethu, le datha ayibakhululi abaprosesa ekwenzeni uphando lwabo kunye novavanyo; kwaye le datha ayithethi siqinisekiso seempawu ezithile, okanye ukufaneleka kwemveliso ngenjongo ethile. Naziphi na iinkcazo, imizobo, iifoto, idatha, ubungakanani, ubunzima, njl.njl. ezinikwe apha zinokutshintsha ngaphandle kolwazi lwangaphambili kwaye aziyiyo umgangatho wesivumelwano esivunyiweyo wemveliso. Umgangatho wesivumelwano esivunyiweyo wemveliso uvela kuphela kwiingxelo ezenziwe kwinkcazo yemveliso. Luxanduva lomntu ofumana imveliso yethu ukuqinisekisa ukuba nawaphi na amalungelo obunini kunye nemithetho ekhoyo kunye nomthetho ziyalandelwa.
