ISAKHIWO:
Incazelo:
Iyi-homopolymer exhumene ne-vinylpyrrolidone emsulwa. Iyimpuphu emhlophe noma emhlophe egeleza ngokukhululekile. Inephunga elibi kancane. Ayincibiliki ezinyibilikisini ezivamile ezifana namanzi, i-ethanol kanye ne-ether. Ngakho-ke ububanzi besisindo sayo se-molecule abunakulinganiswa. Kodwa-ke, i-PVP inamandla okwenza izinto eziyinkimbinkimbi ngezinhlobo ezahlukene zezinto (njengento yesigaba "se-Hu" engaholela ekushintsheni kombala kwezinhlobo ezahlukene zewayini neziphuzo). Futhi isuswa kalula ngemva kokuhlunga ngenxa yokungancibiliki kwayo.

Ukusetshenziswa
1. Imboni yezimonyo: Uchungechunge lwe-PVPK lungasetshenziswa njenge-dispersant, i-ejenti yokwakha ifilimu, i-thickener, i-lubricant kanye ne-adhesive embonini yezimonyo, futhi lungasetshenziswa emikhiqizweni yokunakekelwa kwezinwele njenge-hair spray, i-mousse, i-hair fixative gel, i-shampoo, i-hair fixative kanye ne-hair dye; Imikhiqizo yokunakekelwa kwesikhumba efana ne-lipstick, i-sunscreen, i-moisturizer kanye nezinye izimonyo ezifana ne-modifiers, i-deodorant, i-toothpaste, njll.
2. Imboni Yezemithi: I-PVPK30 (ibanga lezemithi) ingenye yezinto ezintsha ezisiza ekwenzeni imithi, ezingasetshenziswa njengesihlanganisi samathebulethi nama-granule, isinyibilikisi kanye nesiqinisi sokujova, usizo lokugeleza kwama-capsule, isihlakazeli sokulungiselela uketshezi kanye nezinto ezifaka imibala, isiqinisi sama-enzyme nemithi ezwela ukushisa, isithasiselo semithi enganyibiliki, isihlanzisi sokuhlanza kanye nesithambisi samaconsi amehlo, kanye ne-ejenti yokwenza ifilimu embozayo. Sekuvele kunemithi engamakhulu esebenzisa i-PVP njengesithambisi. I-PVPK30 yezinga lezemithi ivunyiwe yi-National Medical Administration of the People's Republic of China.
3. Okunye ukusetshenziswa kwezimboni: Kusetshenziswa njengezihlanzi, izinto zokwakha amafilimu, izihlanganisi, nezinye izithasiselo ezimbonini ezifana nopende nopende, amapulasitiki, ama-resins, imicu yengilazi, uyinki, izinamathiseli, insipho, amafilimu ezithombe, amaphilisi, amashubhu kamabonakude, amakhemikhali okukhiqiza, amateyipu okunamathela, izibulali-magciwane, iphepha, ukuphrinta kanye nokudaya izindwangu.
Ukupakisha Nokuthumela
25kg/ikhadibhodi noma isigubhu sepulasitiki, sivalwe futhi sigcinwe ekushiseni kwegumbi, somile, futhi kude nokukhanya.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
