Amakuru - Kuki imyenda ya acetate ihenze

Mu myaka ibiri ishize, abashushanya ibintu bakunze kuvuga "umwenda wa acide acetike" n "" igitambaro cya acide triacetic ", hanyuma bakazenguruka 3d bazenguruka amajwi," ntibabishoboye! " "Urupfu nkunda! Ntushobora kurukoresha!" Ubu bwoko bwimyenda nabwo bukundwa namasosiyete yo murwego rwohejuru mumyaka ibiri ishize, ubwo arihe?

Sangira ibintu byose byumye bya acide acike ako kanya, urihe, kandi mugihe cyo gukora imyenda, dukora imyenda ya acide acike ihenze cyane? Koresha neza.

1. Acide ya asikeumwenda
Fibre ya Acetate ni ubwoko bwa fibre artificiel, ni kimwe cya kabiri cya fibre fibre fibre, ni selile na anhydride ya acetike kugirango ibone fibre acetate, hanyuma ikazunguruka fibre selile. Fibre ya ACETATE, izwi kandi nk'igitambaro cya acetate, ni ukuvuga ko abantu bakunze kuvuga umwenda wa acide acetike, bakunze kwita umwenda wa acetate, uzwi kandi ku izina rya Yasha, ni umushinwa wa homophone ya acetate y'icyongereza.

Fibre ya Acetate irashobora kugabanywamo ubwoko bubiri bwa fibre acetate na fibre eshatu. Ni irihe tandukaniro riri hagati ya vinegere ebyiri na eshatu?

(1) vinegere eshatu ni ubwoko bwa acetate, idafite hydrolysis, kandi urugero rwa esterifique ni rwinshi. Kubwibyo, urumuri nubushyuhe birwanya imbaraga, imikorere yo gusiga irangi ni mibi, kandi igipimo cyo kwinjiza amazi (kizwi kandi nkigipimo cyo kugarura amazi) kiri hasi.
(2) vinegere ebyiri ni ubwoko bwa acetate bwakozwe nyuma ya hydrolysis igice, kandi urugero rwa esterification ruri munsi ya vinegere eshatu. Kubwibyo, imikorere yo gushyushya ntabwo ari nziza nka vinegere eshatu, imikorere yo gusiga irangi kuruta vinegere eshatu, kandi igipimo cyo kwinjiza amazi kiri hejuru ya vinegere eshatu.

2.Imyenda ya aside ya triacetike
Triacetate ikoreshwa muburyo bwo kwerekana imideli. Uyu munsi, twibanze ku mwenda wa triacetate uri mu mwenda mwiza wa acide acetike, bityo triacetate usibye ihenze, ihenze, ihenze ~ umubiri wose ufite ibyiza ~

Triacetate, ku izina rya SOALON, ikomoka ku mbuto zihingwa muri Kanada na Alaska. Ni fibre yuzuye yubukorikori, yahimbwe na Sosiyete yo mu Buyapani ya Mitsubishi Rayon, ubwoko bushya bwimiterere karemano nubuhanga buhanitse bwo guhuza imyenda, hamwe nubworoherane nkibisanzwe, ariko ingaruka zabyo ziragereranywa na fibre artificiel.

Fibre ya Acetate mugikorwa cya esterification, urugero rwa esterification rurenga 2.7, rwitwa fibre triacetate, naho igitambaro gikozwe muri fibre triacetate cyitwa triacetate.

3. PK hamwe na fibre naturel na fibre yakozwe n'abantu

Kugaragara no kurabagirana kwa fibre triacetate bisa nubwa silikeri ya tuteri. Ibyiyumvo byoroheje no koroha nabyo birasa nubudodo bwa tuteri, kandi uburemere bwihariye bwabwo ni bumwe nubwa silikeri ya tuteri, kubwibyo rero ntakidasanzwe kibaho mukumisha hamwe na silike ya tuteri. Ikiranga nuko igiciro cya fibre naturel cyazamutse mumyaka yashize, kandi acide triacetic yabaye umusimbura mwiza.

Kubwibyo, nta gusinzira bidasanzwe nubudodo. Ikiranga nuko igiciro cya fibre naturel cyazamutse mumyaka yashize, kandi acide triacetic yabaye umusimbura mwiza.

(3) Hamwe nibyiza bya fibre naturel, ibi nibyiza kuruta fibre artificiel. Muri icyo gihe, ubworoherane bwa fibre ya viscose nibyiza, ariko kandi byoroshye gusiga irangi, kandi kwihuta kwamabara ni hejuru.

4.Gukoresha no gushyira imyenda ya acide acike mugushushanya imyenda

Igiciro cyimyenda ya acide acike ihenze, hafashwe umwanzuro wo gukoresha imyenda yo murwego rwohejuru, hamwe nibindi bikoresho bya satine, cyangwa ibikoresho bya TR ntibishobora gusimburwa, ukurikije umukandara wibiciro, kugirango harebwe niba bikwiriye ikirango.

imyambarire yimyambarire yimyambarire yabagore

(1) Igishushanyo mbonera -imyambarire

Umwenda wa acide acike kugirango ukoreimyenda yo kunyerera, nuburyo bwa ace, kandi turashobora kugira inzira nyinshi zitandukanye zo gusobanura dukurikije sag itandukanye yimyenda, kimwe nuburyo bwimyenda.

Ikirango: Ssheena
Ibigize: triacetate 82%, Ethylene 18%)

(2) Igishushanyo mbonera - ipantaro
Cyangwa imvugo ishaje: igishushanyo mbonera cy'ipantaro, ntigishobora gutandukanywa n'ubugari na sag y'igitambara. Ibikoresho bya acide ya acetike ni bimwe, witondere satin kumva acide acike, nayo izahuza phenomenon.
