Amavuta yera 26 CAS NO.8042-47-5
Ibicuruzwa bisobanura
- Amavuta yera ， ubusanzwe bivuga amavuta yera.Ni amavuta yihariye yatunganijwe neza.Amavuta yera ntagira ibara, nta mpumuro nziza, imiti yimbuto, kandi ifite urumuri rwiza.Ibanze shingiro ryamavuta yera ni hydrocarubone yuzuye.Hydrocarbone ya aromatic, azote, ogisijeni, sulfure nibindi bintu byegeranye na zeru.Kubera ubujyakuzimu buhebuje, biragoye gushyira mubikorwa ibice biremereye mubikorwa nyirizina byo gukora, bityo uburemere bwa molekile bwamavuta yera mubusanzwe buri hagati ya 250-450.Ifite okiside nziza, ituze ryimiti, ituze ryumucyo, idafite ibara, impumuro nziza, kandi ntishobora kwangiza imyenda ya fibre.
- Amavuta yera (amavuta yubumara) yitwa amavuta yera cyangwa amavuta yera mumirima imwe n'imwe.Bikunze gukoreshwa ni amavuta yera yo mu rwego rwinganda, amavuta yo kwisiga yo mu rwego rwo kwisiga, amavuta yera yo mu rwego rwubuvuzi, hamwe namavuta yera yo mu rwego rwo hejuru.Ubwoko butandukanye bwamavuta yera afite imikoreshereze itandukanye.
- Amavuta yo kwisiga yo mu rwego rwo kwisiga aboneka nyuma yo gutunganywa cyane hamwe nibikoresho bya hydrogène.Irakwiriye mu nganda zo kwisiga kandi irashobora gukoreshwa nkamavuta yibanze yamavuta yoroshya nka cream cream, amavuta yimisatsi, lipstick, amavuta yo mumaso, amavuta yita kuruhu, amavuta yizuba, amavuta yumwana, amavuta yo kubura, nibindi.
- Amavuta yo kwisiga yo mu rwego rwo kwisiga arashobora gukoreshwa nkibintu birwanya antistatike, emollient, solvent, solvent, na hydrocarubone, bishobora kongera ibyiyumvo byubushuhe, ariko ntibishobora guteza imbere uruhu rwumye kandi rwangiritse.Hariho ibitekerezo bitandukanye byerekeranye no kumenya niba amavuta yubumara yangiza uruhu, ariko birashidikanywaho ko amavuta yubumara yanduye ashobora gutera allergie nibintu bitera acne, kandi abantu basanzwe bafite ibibazo byangiritse cyangwa uruhu rworoshye bagomba kwirinda kubikoresha.Kubera ibara n'ibiranga, ikoreshwa kenshi mumiti ya cream yera cyangwa ibicuruzwa byita kuruhu.
Ibiranga ibicuruzwa
Amavuta yera ni amavuta adafite ibara risukuye kandi nta fluorescence.Ntabwo impumuro nziza kandi itaryoshye iyo hakonje.Ifite impumuro ya peteroli nkeya iyo ishyushye.Ntishobora gushonga mumazi na Ethanol, gushonga mumavuta ahindagurika, kandi ntibishobora kuboneka mumavuta menshi adahindagurika.Umucyo, ubushyuhe, aside, nibindi birahagaze, ariko kumara igihe kinini kumurika nubushyuhe bizagenda bihinduka buhoro buhoro.
Agace gato, imbaraga zikomeye zo gushonga hamwe no guhindagurika kwiza;
- Hydrocarubone yuzuye irenze 99%, kandi ibicuruzwa bifite umutekano uhamye
- Amazi meza ya sulfure, impumuro nziza, idafite uburozi, uburyohe
- Ntabwo ifite ibara, uburyohe, ntabwo ari uburozi, ntabwo yaka, idaturika, ifite ituze ryiza, irwanya urumuri, imiti ihamye, ntabwo yangiza imyenda ya fibre, ntigira uburakari kuruhu, kandi ifitanye isano.
