Nsalu ya acetate, yomwe imadziwikanso kuti nsalu ya acetate, yomwe imadziwikanso kuti Yasha, ndi matchulidwe achi China achingelezi a ACETATE. Acetate ndi ulusi wopangidwa ndi anthu womwe umapezeka ndi esterification ndi acetic acid ndi cellulose ngati zopangira. Acetate, omwe ali m'gulu la ulusi wopangidwa ndi anthu, amakonda kutsanzira ulusi wa silika. Amapangidwa ndiukadaulo wapamwamba wa nsalu, wokhala ndi mitundu yowala komanso mawonekedwe owala. Kukhudza kwake kumakhala kosalala komanso kofewa, ndipo kunyezimira ndi kachitidwe kamakhala pafupi ndi silika wa mabulosi.
Poyerekeza ndi nsalu zachilengedwe monga thonje ndi bafuta, nsalu ya acetate imakhala ndi mayamwidwe abwinoko a chinyontho, mpweya wabwino komanso kupirira, palibe magetsi okhazikika ndi ma hairballs, ndipo imakhala yabwino motsutsana ndi khungu. Ndizoyenera kwambiri kupanga madiresi apamwamba, masiketi a silika, ndi zina zotero. Nthawi yomweyo, nsalu ya acetate ingagwiritsidwenso ntchito m'malo mwa silika wachilengedwe kuti apange zovala zapamwamba zamtundu wapamwamba, monga malaya amtundu, malaya achikopa, madiresi, cheongsams. , madiresi aukwati, masuti a Tang, masiketi achisanu ndi zina zambiri! Choncho aliyense amauona ngati m'malo mwa silika. Zotsatira zake zitha kuwoneka pamizere ya masiketi kapena malaya.
Ulusi wa Acetate ndi chinthu chachilengedwe chochokera ku cellulose yamatabwa, yomwe ndi gawo la molekyulu yofanana ndi ulusi wa thonje, ndi acetic anhydride ngati zopangira. Itha kugwiritsidwa ntchito popota ndi kuluka pambuyo pokonza mankhwala osiyanasiyana. Acetate filament fiber, yomwe imatenga mapadi ngati mafupa oyambira, imakhala ndi mawonekedwe a cellulose fiber; koma machitidwe ake ndi osiyana ndi a ulusi wopangidwanso wa cellulose (viscose cupro silika), ndipo ali ndi mawonekedwe ena a ulusi wopangira:
1. Thermoplasticity yabwino: Chingwe cha acetate chimafewetsa pa 200 ℃ ~ 230 ℃ ndipo chimasungunuka pa 260 ℃. Izi zimapangitsa kuti fiber ya acetate ikhale ndi thermoplasticity yofanana ndi ya ulusi wopangira. Pambuyo pakuwonongeka kwa pulasitiki, mawonekedwewo sadzachira, ndipo kusinthika kudzakhala kosatha. Nsalu ya Acetate imakhala ndi mawonekedwe abwino, imatha kukongoletsa mapindikidwe a thupi la munthu, ndipo ndiyowolowa manja komanso yokongola.
2. Utoto wabwino kwambiri: Ulusi wa acetate nthawi zambiri ukhoza kupakidwa utoto ndi utoto wobalalika, ndipo umakhala ndi mawonekedwe abwino amitundu ndi mitundu yowala, ndipo mawonekedwe ake amapaka amakhala abwino kuposa ulusi wina wa cellulose. Nsalu ya Acetate ili ndi thermoplasticity yabwino. Fiber ya acetate imafewetsa pa 200 ° C ~ 230 ° C ndipo imasungunuka pa 260 ° C. Mofanana ndi ulusi wopangidwa, mawonekedwewo sadzachira pambuyo pa kusinthika kwa pulasitiki, ndipo kumakhala ndi kusinthika kosatha.
3. Maonekedwe ngati silika wa mabulosi: Maonekedwe a ulusi wa acetate amafanana ndi silika wa mabulosi, ndipo kamvekedwe kake kofewa ndi kosalala ka dzanja kamafanana ndi ka silika ka mabulosi. Kukoka kwake kwenikweni ndi kofanana ndi silika wa mabulosi. Nsalu yolukidwa kuchokera ku silika wa acetate ndi yosavuta kuchapa ndi kuuma, ndipo ilibe mildew kapena njenjete, ndipo kutsekemera kwake kuli bwino kuposa ulusi wa viscose.
4. Kuchita kwake kuli pafupi ndi silika wa mabulosi: poyerekeza ndi mawonekedwe a thupi ndi makina a viscose fiber ndi silika wa mabulosi, mphamvu ya acetate fiber imakhala yochepa, elongation panthawi yopuma imakhala yokulirapo, ndipo chiŵerengero cha mphamvu zonyowa kuti ziume mphamvu. ndi otsika, koma apamwamba kuposa silika wa viscose. , modulus yoyamba ndi yaying'ono, kuyambiranso kwa chinyezi kumakhala kochepa kuposa silika wa viscose ndi mabulosi a mabulosi, koma apamwamba kuposa a ulusi wopangira, chiŵerengero cha mphamvu yonyowa kuti iume mphamvu, mphamvu yolumikizira wachibale ndi mphamvu yolumikizira, kuchira kolimba, etc. chachikulu. Chifukwa chake, zinthu za ulusi wa acetate ndizoyandikana kwambiri ndi silika wa mabulosi pakati pa ulusi wamankhwala.
5. Nsalu ya acetate ilibe magetsi; sikophweka kuyamwa fumbi mumlengalenga; kuyeretsa kouma, kuchapa madzi ndi kusamba m'manja mwa makina pansi pa 40 ℃ kungagwiritsidwe ntchito, zomwe zimagonjetsa kufooka kwa nsalu za silika ndi ubweya zomwe nthawi zambiri zimakhala zonyamula mabakiteriya; yafumbi ndipo imatha kutsukidwa mouma, ndipo palibe nsalu zaubweya zomwe zimakhala zosavuta kudyedwa ndi tizilombo. Zoyipa zake ndikuti ndizosavuta kusamalira ndi kusonkhanitsa, ndipo nsalu ya acetate imakhala yokhazikika komanso yosalala ya nsalu zaubweya.
Zina: Nsalu ya Acetate ili ndi kuposa nsalu za thonje ndi nsalu zokhala ndi zinthu zosiyanasiyana, monga kuyamwa kwa chinyezi ndi kupuma, palibe thukuta, zosavuta kutsuka ndi kuuma, palibe mildew kapena njenjete, zomasuka pakhungu, zokonda zachilengedwe, ndi zina zotero.
