O le ā le fa'aaogāga o le 4 4'-Diaminodiphenylsulfone?

4 4 '- diaminodiphenyl sulfone o se vailaʻau sulfone manogi taua e faʻaleleia e ala i le faʻagasologa o le ammonification i le vevela maualuga ma le mamafa maualuga. E faʻaaogaina tele i le faʻapipiʻiina o polysulfone amide resins ma isi mea faʻapipiʻi polymer, faʻapea foʻi ma le faʻapipiʻiina o le tele o vali azo acidic ma vali faʻasalalau.

4 4 '- E mafai ona fa'aaogaina le Diaminodiphenylsulfone o se vaila'au fa'amālōlō mo le epoxy resin ma mea e fa'amafanafana ai i le alamanuia eletise, masini ie, ma o se mea e fa'aoso ai le vevela. E mafai fo'i ona fa'aaogaina i le alamanuia vaila'au e togafitia ai le lepela, herpes e pei o le dermatitis, AIDS, ma isi tulaga.

Teuina ma Fuafuaga Fesoasoani Muamua

E tatau ona fa'amaufa'ailogaina le 4,4'-Diaminodiphenylsulfone ma teu 'ese mai le malamalama. E tatau ona teuina i se nofoaga malūlū ma mago. Ia fa'amaufa'ailogaina pe a le fa'aaogaina.

Fuafuaga fesoasoani muamua

Pa'i i mata: Si'i i luga laumata ma fufulu i le vai tafe po'o le vaila'au masima. Saili se fesoasoani fa'afoma'i. Fufulu lelei i le vai. Saili se fesoasoani fa'afoma'i.

Manava i totonu: Ia vave ona tuua le nofoaga ma agai atu i se nofoaga e iai le ea fou. Ia aua ne'i poloka le ala manava. Afai e faigata ona manava, tu'u atu le okesene. Afai e taofi le manava, ia vave faia le manava fa'apitoa. Saili se fesoasoani faafoma'i.

Fa'aaogaina: Inu le tele o le vai mafanafana ma fa'amalosi e pua'i. Saili se fesoasoani fa'afoma'i.
