Chifukwa chiyani nsalu za acetate ndizokwera mtengo?

M'zaka ziwiri zapitazi, okonza nthawi zambiri amati "nsalu ya acetic acid" ndi "nsalu ya triacetic acid", ndiyeno iwo adzakhala 3d kuzungulira phokoso, "sangakwanitse!" "Wokondedwa imfa! Simungagwiritse ntchito!" Nsalu zamtunduwu ndizomwe zimakondanso makampani apamwamba kwambiri m'zaka ziwiri zapitazi, ndiye kuti?

Gawani mitundu yonse ya zinthu zouma za asidi acetic nthawi yomweyo, muli kuti, ndipo popanga zovala, timapanga nsalu za acetic zodula kwambiri? Gwiritsani ntchito bwino.

1.Acetic acidnsalu
Ulusi wa Acetate ndi mtundu wa ulusi wochita kupanga, ndi semi-synthetic fiber material, ndi mapadi ndi acetic anhydride reaction kuti apeze CHIKWANGWANI cha acetate, ndiyeno spun cellulose acetate ulusi wopangidwa. CHIKWANGWANI cha ACETATE, chomwe chimadziwikanso kuti nsalu ya acetate, ndiye kuti, anthu nthawi zambiri amati nsalu ya acetic, yomwe imadziwikanso kuti nsalu ya acetate, yomwe imadziwikanso kuti Yasha, ndi homophone yaku China ya English acetate.

zovala za akazi

Ulusi wa acetate ukhoza kugawidwa mu mitundu iwiri ya acetate fiber ndi atatu acetate fiber. Kodi pali kusiyana kotani pakati pa vinegars ziwiri ndi zitatu?

(1) Vinegar atatu ndi mtundu wa acetate, wopanda hydrolysis, ndipo digiri yake ya esterification ndi yapamwamba. Chifukwa chake, kukana kwa kuwala ndi kutentha kumakhala kolimba, ntchito yopaka utoto ndiyosauka, komanso kuchuluka kwa chinyezi (komwe kumatchedwanso kuti chinyezi kuyambiranso) kumakhala kotsika.
(2) Viniga awiri ndi mtundu wa acetate wopangidwa pambuyo pa hydrolysis pang'ono, ndipo mlingo wake wa esterification ndi wotsika kuposa wa viniga atatu. Chifukwa chake, ntchito yotenthetsera sibwino ngati vinyo wosasa atatu, ntchito yopaka utoto ndiyabwino kuposa viniga atatu, ndipo kuchuluka kwa mayamwidwe a chinyezi ndikokwera kuposa viniga atatu.

2.Triacetic acid nsalu
Triacetate nthawi zambiri imagwiritsidwa ntchito popanga mafashoni athu. Masiku ano, timayang'ana kwambiri pansalu ya triacetate yomwe ili munsalu yabwino ya acetic acid, kotero triacetate kuphatikiza zodula, zodula, zodula ~ thupi lonse lili ndi zabwino ~

Triacetate, pansi pa dzina lakuti SOALON, imachokera ku ma conifers omwe amakula ku Canada ndi Alaska. Ndi ulusi woyera wa semi-artificial, wopangidwa ndi Mitsubishi Rayon Company ya ku Japan, mtundu watsopano wa nsalu zachilengedwe komanso zamakono zamakono, zofewa mofanana ndi ulusi wachilengedwe, koma zotsatira zake zimafanana ndi ulusi wochita kupanga.

Ulusi wa acetate mu njira ya esterification, digiri ya esterification ndi yoposa 2.7, imatchedwa triacetate fiber, ndipo nsalu yopangidwa ndi triacetate fiber imatchedwa nsalu ya triacetate.

3. PK yokhala ndi ulusi wachilengedwe komanso ulusi wopangidwa ndi anthu

Maonekedwe ndi kuwala kwa ulusi wa triacetate amafanana ndi silika wa mabulosi. Kumverera kwa kufewa ndi kusalala kumafanananso ndi silika wa mabulosi, ndipo mphamvu yake yokoka ndi yofanana ndi ya mabulosi a mabulosi a silika, kotero palibe cholakwika mu kuuma ndi silika wa mabulosi. Chikhalidwe chake ndi chakuti mtengo wa ulusi wachilengedwe wakhala ukukwera m'zaka zaposachedwa, ndipo triacetic acid yakhala m'malo mwabwino.

Choncho, palibe drapiness zachilendo ndi silika. Chikhalidwe chake ndi chakuti mtengo wa ulusi wachilengedwe wakhala ukukwera m'zaka zaposachedwa, ndipo triacetic acid yakhala m'malo mwabwino.

kavalidwe ka akazi

Zopambana:
(1) Nsalu ya silika yokhala ndi mabakiteriya, fumbi komanso kutsukidwa kouma, koma sikovuta kupanga magetsi osasunthika, sikovuta kuyamwa fumbi mumlengalenga, ndipo palibe nsalu ya silika yosavuta kudya zolephera, zosavuta kuzitenga. chisamaliro cha.
(2) Ali ndi thermoplasticity yabwino, mawonekedwe ake ndi osavuta kukonza, poyerekeza ndi zinthu za hemp, zosavuta kukwinya, ndi ntchito ya mayamwidwe a chinyontho, nthawi yomweyo, ndikumva dzanzi, kumva kuzizira povala.
(3) Ndi chitonthozo cha ulusi wachilengedwe, izi ndizabwino kuposa ulusi wochita kupanga. Pa nthawi yomweyo, elasticity wa viscose CHIKWANGWANI ndi bwino, komanso zosavuta utoto, ndipo mtundu fastness ndi apamwamba.

4.Kugwiritsa ntchito ndi kuyika kwa nsalu ya acetic mu kapangidwe ka zovala

Mtengo wa nsalu ya acetic acid ndi wokwera mtengo, umaganiziridwa kuti ugwiritse ntchito zovala zapamwamba, ndi satin zina, kapena zinthu za TR sizingasinthidwe, malinga ndi lamba wamtengo wapatali, kuti awone ngati ali oyenera chizindikiro.

zovala zachikazi zamakono zamakono

(1) Kapangidwe ka mafashoni --kuvala

Acetic asidi nsalu kuchitazovala zoterera, ndi njira ya ace, ndipo tikhoza kukhala ndi njira zambiri zotanthauzira molingana ndi sag yosiyana ya nsalu, komanso kalembedwe ka nsalu.

zovala zovala kwa atsikana

Chizindikiro: Ssheena
Zosakaniza: triacetate 82%, ethylene 18%)

(2)Kapangidwe ka mafashoni -- mathalauza
Kapena mwambi wakale: kalembedwe ka mathalauza, sangathe kulekanitsidwa ndi m'lifupi ndi sag ya nsalu. Acetic acid zakuthupi ndi yemweyo, tcherani khutu kumverera kwa satin wa asidi acetic, nawonso mbedza chodabwitsa.
