Waba uzi mubyukuri imyenda ya Acetate?

Imyenda ya acetate ikozwe muri fibre acetate. Ni fibre artificiel, ifite ibara ryiza, igaragara neza, yoroshye, yoroshye kandi nzizaikiganza. Kumurika no gukora byegereye silik.

Ibikoresho bya Shimi

Kurwanya Alkali

Ahanini, intege nke za alkaline ntizangiza fibre acetate. Iyo uhuye na alkali ikomeye, cyane cyane fibre ya diacetate biroroshye kubaho deacetylation, biganisha kugabanya ibiro. Na none imbaraga na modulus bizagabanuka.

Kurwanya Acide

Fibreifite aside nziza. Acide ya sulfurike ikunze kugaragara, aside hydrochloric na acide ya nitric hamwe nibitekerezo bimwe ntabwo bizahindura imbaraga, kurabagirana no kurambura fibre. Ariko fibre ya acetate irashobora gushonga muri acide sulfurike yibanze, aside hydrochloric na aside nitric.

Kurwanya Kurwanya Kurwanya

Fibre ya Acetate irashobora gushonga rwose muri acetone, DMF na acide glacial acetic. Ariko ntizishonga muri alcool ya Ethyl cyangwa tetrachlorethylene.

Imikorere yo gusiga irangi

Amabara asanzwe akoreshwa kuriirangiselile ya selile idafite aho ihuriye na fibre acetate, bigoye gusiga fibre acetate. Irangi ryiza cyane rya fibre acetate ni amarangi atatanya, afite uburemere buke bwa molekile hamwe nigipimo cyo gusiga irangi.

Ibintu bifatika

Fibre ya Acetate ifite ubushyuhe bwiza. Ubushyuhe bwikirahure-fibre ya fibre igera kuri 185 ℃ naho ubushyuhe bwo kurangiza gushonga ni 310 ℃. Iyo ihagaritse gushyushya, igipimo cyo kugabanya fibre kizaba 90,78%. Igabanuka ryayo ryamazi abira ni make. Ariko gutunganya ubushyuhe bwinshi bizagira ingaruka kumbaraga no kurabagirana kwa fibre acetate. Ubushyuhe rero bugomba kuba munsi ya 85 ℃.

Fibre ya Acetate ifite ubuhanga bworoshye, hafi yubudodo nubwoya.
