ULWAKHIWO:
Inkcazo:
Yi-homopolymer edityanisiweyo ye-vinylpyrrolidone ecocekileyo. Ingumgubo omhlophe okanye omhlophe ohamba ngokukhululekileyo. Inevumba elibi kancinci. Ayinyibiliki kwizinyibilikisi eziqhelekileyo ezifana namanzi, i-ethanol kunye ne-ether. Ngoko ke ubunzima bayo beemolekyuli abunakulinganiswa. Nangona kunjalo, i-PVP inamandla okwenza izinto ezahlukeneyo (ezifana ne-"Hu" class substance enokukhokelela ekutshintsheni kombala kwiindidi ezahlukeneyo zeewayini kunye neziselo). Kwakhona kulula ukuyisusa emva kokuhluzwa ngenxa yokunganyibiliki kwayo.

Ukusetyenziswa
1. Ishishini lezinto zokuthambisa: Uthotho lwePVPK lungasetyenziswa njenge-dispersant, i-arhente yokwenza ifilimu, i-thickener, i-lubricant kunye ne-adhesive kwishishini lezinto zokuthambisa, kwaye lungasetyenziswa kwiimveliso zokhathalelo lweenwele ezifana ne-hair spray, i-mousse, i-hair fixative gel, i-shampoo, i-hair fixative kunye ne-hair dye; Iimveliso zokhathalelo lolusu ezifana ne-lipstick, i-sunscreen, i-moisturizer kunye nezinye izinto zokuthambisa ezifana ne-modifiers, i-deodorants, i-toothpaste, njl.
2. Ishishini leMithi: I-PVPK30 (udidi lweyeza) yenye yezinto ezintsha ezisetyenziselwa ukwenziwa kwamayeza, ezinokusetyenziswa njengesihlanganisi samacwecwe kunye neegranules, isinyibilikisi kunye nesiqinisi sokujova, uncedo lokuhamba kweekhaphu, isinyibilikisi sokulungiselela ulwelo kunye neearhente zokufaka imibala, isiqinisi see-enzyme kunye namayeza ashushu, isinyibilikisi samayeza anganyibilikiyo, isicoci kunye nesithambisi samaconsi amehlo, kunye nearhente yokwenza ifilimu yokugquma. Sele kukho amakhulu amachiza asebenzisa i-PVP njengesincedisi. I-PVPK30 yodidi lweyeza ivunyiwe yi-National Medical Administration of the People's Republic of China.
3. Ezinye iindlela zokusetyenziswa kwemizi-mveliso: Zisetyenziswa njengezinto zokusasaza, izinto zokwenza ifilimu, izinto ezixubayo, kunye nezinye izongezo kwimizi-mveliso efana neepeyinti kunye neengubo, iiplastiki, iiresini, iifayibha zeglasi, ii-inki, izinto zokuncamathelisa, izicoci, iifilimu zeefoto, iitafile, iityhubhu zikamabonwakude, iikhemikhali zokwenza imveliso, iiteyiphu zokuncamathelisa, izibulali-ntsholongwane, iphepha, ukuprinta kunye nokudaya impahla.
Ukupakishwa kunye nokuthunyelwa
I-25kg/ikhadibhodi okanye idrama yeplastiki, ivalwe kwaye igcinwe kubushushu begumbi, yomile, kwaye ikude nokukhanya.
Yeyokwempahla eqhelekileyo kwaye inokuhanjiswa ngolwandle nangomoya
Gcina kwaye ugcine
Ixesha lokuphelelwa: Iinyanga ezingama-24 ukususela kumhla wokwenziwa kwayo kwiphakheji yokuqala engavulwanga igcinwe kwindawo epholileyo neyomileyo kude nelanga elithe ngqo, amanzi.
Indawo yokugcina umoya, Ukomisa kubushushu obuphantsi, Yahlulwe kwii-oxidants, ii-asidi.
