Ukunamathela kwinkolelo yakho yokuba "ukudala izisombululo ezisemgangathweni kunye nokuvelisa amachwephesha abantu abavela kwihlabathi liphela" Wamkelekile bonke abahlobo ukubeka ilitye lokuvavanywa kwetyala ngokwenza ubudlelwane bexesha elide.
Ukunamathela kwinkolelo yakho 'yokwenza isisombululo somgangatho ophezulu kunye nokuvelisa amayeza abantu abavela kwihlabathi liphela ", sihlala sibeka umtsalane kubathengi ukuqalaIxabiso eliphantsi, Uphando lwekhemikhali, Inkampani yethu ihleli ngombono wolawulo 'wokugcina ubuchule, buhlungu ngokugqwesa'. Kwisiseko sokuqinisekisa ubuninzi bezinto ezikhoyo zezisombululo, sisomeleza kwaye sandisa uphuhliso lwemveliso. Inkampani yethu inyanzelisa ubuchule bokuphakamisa ukukhula okuzinzileyo kweshishini, kwaye kusenze sibe ngabathengisi abakumgangatho ophezulu basekhaya.

Umsebenzi
I-DMac isetyenziswa ikakhulu njenge-solvent ye-synthitic (i-acrylonile) kunye ne-polyirethane inyibilika kwaye isetyenziswa njengeziqhelanisa ne-Polymer, kwaye isetyenziswa ngokubanzi kwiifilimu ze-POLYMER, kwaye isetyenziswa ngamayeza, njl. Okwangoku, isetyenziswa ngokubanzi kumayeza kwaye iheke ihesu lokuyifumana i-antibiotics kunye nezibulala-zinambuzane. Ingasetyenziswa njengeyona nto ibaluleke kakhulu ekuphenduleni, isinyikithi sombane, i-scavenger yepeyinti, kunye neendidi ze-creestalline ze-cristalline ze-crstalline kunye nezibini.
Inkcazo
N, n-dimithylacetamide, ekwabizwa ngokuba yi-acetylmanemine, i-Acetldlimplamine, okanye i-DMC ye-odor ye-ammia i-ammia i-ammor enesidima, kunye noluhlu lwezinto ezinyibilikayo. Ingabonakali ngokubanzi ngamanzi, imingxunya enombala, amaKeds, i-COSOLS, i-Eni, i-Ben, i-Bensene, njl. Njl. Ngokwesinyibilikisi, njengesinyibilikisi esiphezulu, indawo ephakamileyo ye-flash, uzinzo lwe-vinya kunye ne-vinyl ye-vinya, i-vinyl pyprine kunye ne-carxboxy ye-calboxylic slid; Ngokwenyani, ingasetyenziswa kwinkqubo yokufudumeza u-Irea ukuba ivelise i-Alkyl ye-Alkyl kunye ne-Alkyl ye-Alkyl ye-Alkyl Alkyle, kunye nempendulo ye-halide ye-organic kunye ne-hanate yokuvelisa i-madonate. N, i-N-Dimithylacetamide inokusetyenziswa njengesinyibilikisi seSolventisis Solvent kunye nesibini esitshatileyo, ipeyinti yepeyinti, i-orntac synthesic synthesical synthes, iyeza lezinto ezenziwa ngamayeza. Ukukhutshwa kwezintlukwano zesilivere zokwahlula isitayile ukusuka kwinxalenye ye-C8, njl.
Ukunamathela kwinkolelo yakho yokuba "ukudala izisombululo ezisemgangathweni kunye nokuvelisa amachwephesha abantu abavela kwihlabathi liphela" Wamkelekile bonke abahlobo ukubeka ilitye lokuvavanywa kwetyala ngokwenza ubudlelwane bexesha elide.
Ukuhlolwa komgangathoUphando lwekhemikhali, Ixabiso eliphantsi, Inkampani yethu ihleli ngombono wolawulo 'wokugcina ubuchule, buhlungu ngokugqwesa'. Kwisiseko sokuqinisekisa ubuninzi bezinto ezikhoyo zezisombululo, sisomeleza kwaye sandisa uphuhliso lwemveliso. Inkampani yethu inyanzelisa ubuchule bokuphakamisa ukukhula okuzinzileyo kweshishini, kwaye kusenze sibe ngabathengisi abakumgangatho ophezulu basekhaya.
