Amakuru - Kuki imyenda ya acetate ihenze

Mu myaka ibiri ishize, abashushanya bakunze kuvuga "imyenda ya aside asetiki" na "imyenda ya aside triasetiki", hanyuma bagakora uruziga ruzunguruka mu buryo bwa 3D, "ntabwo nshobora kubyishyura!" "Wapfuye we! Sinshobora kuyikoresha!" Ubu bwoko bw'imyenda ni nabwo bukunzwe cyane n'ibigo by'ubucuruzi byo mu rwego rwo hejuru mu myaka ibiri ishize, none se buri he?

Sangiza ubwoko bwose bw'ibintu byumye bya aside asetiki ako kanya, uri he, kandi mu gihe cyo gushushanya imyenda, duhenda cyane imyenda ya aside asetiki? Ikoreshe neza.

1.Aside asetikiumwenda
Fibre ya asetatike ni ubwoko bwa fibre y’ubukorano, ni fibre ikoze muri semi-synthetic, ni cellulose na acetic anhydride reaction kugira ngo fibre acetate iboneke, hanyuma fibre ya asetatike ya setatike irakorwa. Fibre ya asetatike, izwi kandi ku izina rya acetate, ni ukuvuga ko abantu bakunze kuvuga ko imyenda ya aside asetatike, izwi cyane ku izina rya acetate, izwi kandi ku izina rya Yasha, ni homophone y’Abashinwa ya acetate y’Icyongereza.

Fibre ya acetate ishobora kugabanywamo ubwoko bubiri bwa fibre ya acetate n'ubwoko butatu bwa fibre ya acetate. Ni irihe tandukaniro riri hagati ya vinegere ebyiri n'eshatu?

(1) Vinegere eshatu ni ubwoko bwa acetate, idafite hydrolysis, kandi urwego rwayo rwo gupima ubushyuhe ruri hejuru. Kubwibyo, urumuri n'ubushyuhe birakomeye, imikorere yo gusiga irangi ni mibi, kandi igipimo cyo kwinjiza ubushuhe (kizwi kandi nka moisture recover rate) ni gito.
(2) Vinegere ebyiri ni ubwoko bwa acetate bukorwa nyuma yo gushonga igice, kandi urwego rwa esterification yabyo ruri hasi ugereranije n’urwa vinegere eshatu. Kubwibyo, imikorere yo gushyushya ntabwo ari myiza nka vinegere eshatu, imikorere yo gusiga irangi ni myiza kurusha vinegere eshatu, kandi igipimo cyo kwinjiza ubushuhe kiri hejuru ugereranyije na vinegere eshatu.

2.Igitambaro cya aside triasetike
Triacetate ikunze gukoreshwa mu miterere yacu. Muri iki gihe, twibanda ku mwenda wa triacetate ugizwe n'umwenda mwiza wa aside asetiki, bityo triacetate usibye ihenze, ihenze, kandi ihenze ~ umubiri wose ufite ibyiza ~

Triacetate, izina rya SOALON, ikomoka ku bimera bya conifer bihingwa muri Kanada na Alaska. Ni fibre y’ubukorano, yavumbuwe na Mitsubishi Rayon Company yo mu Buyapani, ubwoko bushya bw’imyenda karemano n’iy’ikoranabuhanga rigezweho, ifite ubworoherane nk’ubw’imyenda karemano, ariko ingaruka zayo zigereranywa n’imyenda y’ubukorano.

Fibre ya asetatike mu gikorwa cyo gupima ubuziranenge bw'ibice, urwego rwa esterification rurenze 2.7, rwitwa fibre ya triacetate, naho umwenda ukozwe muri fibre ya triacetate witwa umwenda wa triacetate.

3. PK ifite insinga karemano n'insinga zakozwe n'abantu

Isura n'ububengerane bya fibre ya triacetate bisa n'iby'ubudodo bwa mulberry. Ukumva ko bworoshye kandi bunoze nabyo bisa n'iby'ubudodo bwa mulberry, kandi uburemere bwabwo bwihariye ni bumwe n'ubw'ubudodo bwa mulberry, bityo nta kintu kidasanzwe kigaragara mu budodo bwumye n'ubw'ubudodo bwa mulberry. Ikiranga ni uko igiciro cy'ubudodo karemano cyakomeje kuzamuka mu myaka ya vuba aha, kandi aside triacetic yabaye igikoresho cyiza cyo gusimbura.

Bityo rero, nta budodo budasanzwe na silk bibaho. Ikiranga ni uko igiciro cy'imigozi karemano cyakomeje kuzamuka mu myaka ya vuba aha, kandi aside triasetike yabaye igikoresho cyiza cyo gusimbura.

Amanota yo gutsinda:
(1) Igitambaro cy'ubudodo gifite bagiteri, umukungugu kandi gishobora gusukurwa gusa, ariko nticyoroshye gukora amashanyarazi adahindagurika, nticyoroshye kwinjiza umukungugu mu kirere, kandi nta gitambaro cy'ubudodo cyoroshye kurya, cyoroshye kwitaho.
(2) Ifite ubushobozi bwo gushyuha neza, imiterere yayo yoroshye kuyikosora, ugereranije n'ibikoresho bya hemp, ntabwo byoroshye kuyihindura, ifite ubushobozi bwo kwinjiza ubushuhe bw'ipamba, icyarimwe, ifite ibyiyumvo byo kubura ibinure, ikumva ikonje iyo yambaye.
(3) Kubera ko inyunganiramirire karemano imeze neza, ibi biruta inyunganiramirire. Muri icyo gihe, ubushyuhe bwa viscose ni bwiza kurushaho, ariko kandi biroroshye gusiga irangi, kandi ibara riratinda cyane.

4. Gukoresha no gushyira imyenda ya aside asetiki mu gishushanyo mbonera cy'imyenda

Igiciro cy'imyenda ya aside asetiki kirahenze, hafatwa icyemezo cyo gukoresha imyenda ihenze, hamwe n'indi satin, cyangwa ibikoresho bya TR ntibishobora gusimbuzwa, nk'uko umukandara w'igiciro ubivuga, kugira ngo harebwe niba bikwiriye ikirango.

(1) Igishushanyo mbonera cy'imideli --ikanzu

Igitambaro cya aside asetiki cyo gukoraikanzu yo kwambara, ni uburyo bwa ace, kandi dushobora kugira uburyo bwinshi butandukanye bwo gusobanura dukurikije imiterere itandukanye y'imyenda, ndetse n'imiterere y'imyenda.

Ikirango: Ssheena
Ibikoresho: triacetate 82%, ethylene 18%)

(2) Igishushanyo mbonera cy'imideli -- ipantalo
Cyangwa umugani wa kera: imiterere y'ipantaro, ntabwo ishobora gutandukanywa n'ubugari n'uburebure bw'umwenda. Ibikoresho bya aside asetiki ni bimwe, witondere ibyiyumvo bya satin bya aside asetiki, nabyo bizakurura ibintu.
