Indwangu ye-acetate, evame ukwaziwa ngendwangu ye-acetate, eyaziwa nangokuthi i-Yasha, indlela yokuphimisela ye-Chinese homophonic yesiNgisi i-ACETATE. I-acetate iyifayibha eyenziwe umuntu etholwe nge-esterification ene-acetic acid ne-cellulose njengezinto zokusetshenziswa. I-acetate, engowomndeni wemicu eyenziwe umuntu, ithanda ukulingisa imicu kasilika. Ikhiqizwa ngobuchwepheshe bendwangu obusezingeni eliphezulu, obunemibala egqamile nokubukeka okugqamile. Ukuthinta kubushelelezi futhi kukhululekile, futhi ukucwebezela nokusebenza kusondele kulokho kukasilika kamalibhele.
Uma kuqhathaniswa nezindwangu zemvelo ezifana nekotini nelineni, indwangu ye-acetate inokumunca kangcono umswakama, ukungena komoya kanye nokuqina, akukho ugesi omile namabhola ezinwele, futhi ikhululekile ngokumelene nesikhumba. Ifaneleka kakhulu ukwenza izingubo ezihloniphekile, izikhafu zesilika, njll. Ngasikhathi sinye, indwangu ye-acetate ingasetshenziswa futhi esikhundleni sikasilika wemvelo ukwenza imigqa ehlukahlukene yemfashini yomkhiqizo ophezulu, njengamajazi omsele, amajazi esikhumba, izingubo, ama-cheongsams. , izingubo zomshado, amasudi e-Tang, iziketi zasebusika nokuningi! Ngakho wonke umuntu uwuthatha esikhundleni sikasilika. Imikhondo yayo ingabonakala olwelweni lweziketi noma amajazi.
I-acetate fiber iyinto yemvelo ekhishwe ku-wood pulp cellulose, okuyingxenye yamangqamuzana amakhemikhali afanayo nefayibha kakotini, kanye ne-acetic anhydride njengezinto zokusetshenziswa. Ingasetshenziselwa ukuphotha nokuluka ngemva kochungechunge lokucutshungulwa kwamakhemikhali. I-acetate filament fiber, ethatha i-cellulose njengohlaka lwamathambo oluyisisekelo, inezici eziyisisekelo ze-cellulose fiber; kodwa ukusebenza kwayo kuhlukile kulokho kwefayibha ye-cellulose evuselelwe (usilika we-viscose cupro), futhi inezici ezithile ze-synthetic fiber:
1. I-thermoplasticity enhle: I-acetate fiber iyathamba ku-200℃~230℃ futhi incibilika ku-260℃. Lesi sici senza i-acetate fiber ibe ne-thermoplasticity efana neyemicu yokwenziwa. Ngemuva kokuguqulwa kwepulasitiki, umumo ngeke ululame, futhi ukuguqulwa kuyoba unomphela. Indwangu ye-acetate inokwakheka okuhle, ingahlobisa ijika lomzimba womuntu, futhi iyaphana futhi inhle.
2. Ukudaya okuhle kakhulu: I-acetate fiber ngokuvamile ingadaywa ngamadayi ahlakazayo, futhi inombala omuhle nemibala egqamile, futhi ukusebenza kwayo kombala kungcono kuneminye imicu ye-cellulose. Indwangu ye-acetate ine-thermoplasticity enhle. I-acetate fiber iyathamba ku-200 ° C ~ 230 ° C futhi incibilika ku-260 ° C. Ngokufanayo nemicu yokwenziwa, umumo ngeke ululame ngemva kokuguqulwa kwepulasitiki, futhi unokuguqulwa okuhlala njalo.
3. Ukubukeka njengosilika kamalibhele: Ukubonakala kwefiber ye-acetate kufana nosilika kamalibhele, futhi umuzwa wayo wesandla esithambile nesibushelelezi ufana nolukasilika kamalibhele. Amandla adonsela phansi akhethekile afana nalawo kasilika kamalibhele. Indwangu elukwe ngosilika we-acetate kulula ukuyigeza futhi yome, futhi ayinaso isikhutha noma inundu, futhi ukunwebeka kwayo kungcono kune-viscose fiber.
4. Ukusebenza kusondele kusilika kamalibhele: uma kuqhathaniswa nezakhiwo ezingokomzimba nezomshini ze-viscose fiber nosilika kamalibhele, amandla efiber ye-acetate aphansi, ubude ngesikhathi sekhefu bukhulu, kanye nesilinganiso samandla amanzi ukomisa amandla. iphansi, kodwa iphakeme kunaleyo kasilika we-viscose. , i-modulus yokuqala incane, ukubuyiswa komswakama kuphansi kunaleyo ye-viscose fibre kanye nosilika kamalibhele, kodwa kuphakeme kunaleyo yefayibha yokwenziwa, isilinganiso samandla amanzi ukuze ome amandla, amandla okuhuka okuhlobene namandla okubopha, izinga lokululama lokunwebeka, njll. . Ngakho-ke, izakhiwo ze-acetate fiber zisondele kakhulu kusilika kamalibhele phakathi kwemicu yamakhemikhali.
5. Indwangu ye-acetate ayifakwanga ugesi; akulula ukumunca uthuli emoyeni; ukuhlanza okomile, ukugeza amanzi nokugeza izandla ngomshini ngaphansi kuka-40 ℃ kungasetshenziswa, okunqoba ubuthakathaka bezindwangu zikasilika noboya ezivame ukuthwala amagciwane; ezinothuli futhi zingahlanzwa kuphela, futhi azikho izindwangu zoboya okulula ukudliwa yizinambuzane. Okubi ukuthi kulula ukuyinakekela nokuqoqa, futhi indwangu ye-acetate inokuqina nokuzwakala kahle kwezindwangu zoboya.
Abanye: Indwangu ye-acetate ine futhi idlula izindwangu zekotini nelineni ezinezakhiwo ezihlukahlukene, njengokumuncwa umswakama nokuphefumula, akukho ukujuluka, kulula ukuwasha nokomisa, akukho sikhunta noma inundu, ekhululekile ngokumelene nesikhumba, imvelo ngokuphelele, njll.
