Izindaba - Kungani izindwangu ze-acetate zibiza

Eminyakeni emibili edlule, abaklami bavame ukusho "indwangu ye-acetic acid" kanye "nendwangu ye-triacetic acid", bese bezokwenza i-3d loop ezungeze umsindo, "ayikwazi ukukhokhela!" "Kufa othandekayo! Awukwazi ukuyisebenzisa!" Lolu hlobo lwendwangu luphinde lube yintandokazi yezinkampani zohlobo oluphezulu eminyakeni emibili edlule, khona-ke ikuphi?

Yabelana ngazo zonke izinhlobo zezimpahla ezomile ze-acetic acid ngokushesha, ukuphi, futhi ohlelweni lokudweba izingubo, senza izindwangu ze-acetic ezibiza kakhulu? Yisebenzise kahle.

1.I-acetic acidindwangu
I-acetate fiber iwuhlobo lwefayibha yokwenziwa, iyi-semi-synthetic fiber material, i-cellulose ne-acetic anhydride reaction ukuze ithole i-fiber acetate, bese kwakheka i-cellulose acetate fiber. I-ACETATE fiber, eyaziwa nangokuthi indwangu ye-acetate, okungukuthi, abantu bavame ukusho indwangu ye-acetic acid, eyaziwa ngokuthi indwangu ye-acetate, eyaziwa nangokuthi i-Yasha, i-homophone yesiShayina ye-acetate yesiNgisi.

I-acetate fiber ingahlukaniswa ngezinhlobo ezimbili ze-acetate fiber kanye ne-acetate fiber ezintathu. Uyini umehluko phakathi kwamaviniga amabili namathathu?

(1) Uviniga wesithathu uwuhlobo lwe-acetate, ngaphandle kwe-hydrolysis, futhi izinga layo le-esterification liphakeme. Ngakho-ke, ukumelana nokukhanya nokushisa kunamandla, ukusebenza kokudaya akulungile, futhi izinga lokumunca umswakama (owaziwa nangokuthi izinga lokubuyisela umswakama) liphansi.
(2) Uviniga amabili uwuhlobo lwe-acetate olwakhiwe ngemva kwe-hydrolysis eyingxenye, futhi izinga layo le-esterification liphansi kunalelo lamaviniga amathathu. Ngakho-ke, ukusebenza kokushisisa akukuhle njengeviniga amathathu, ukusebenza kokudaya kungcono kunoviniga amathathu, futhi izinga lokumunca umswakama lingaphezu kukaviniga amathathu.

Indwangu ye-Triacetic acid
I-Triacetate ivame ukusetshenziswa ekwakhiweni kwethu kwemfashini. Namuhla, sigxila endwangu ye-triacetate eyingxenye yendwangu enhle ye-acetic, ngakho-ke i-triacetate ngaphezu kwezindleko ezibizayo, ezibizayo, ezibizayo ~ wonke umzimba unezinzuzo ~

I-Triacetate, ngaphansi kwegama elithi SOALON, isuselwa ku-conifers etshalwe eCanada nase-Alaska. Iwuphawu oluhlanzekile lwe-semi-artificial fiber, yasungulwa yi-Mitsubishi Rayon Company yaseJapane, uhlobo olusha lwenhlanganisela yendwangu yemvelo neyobuchwepheshe obuphezulu, enobuntofo obufanayo njengemicu yemvelo, kodwa umphumela wayo uqhathaniswa nemicu yokwenziwa.

I-acetate fiber enqubweni ye-esterification, izinga le-esterification lingaphezu kuka-2.7, libizwa ngokuthi i-triacetate fiber, kanti indwangu eyenziwe nge-triacetate fiber ibizwa ngendwangu ye-triacetate.

3. I-PK enemicu yemvelo nemicu eyenziwe umuntu

Ukubukeka nokucwebezela kwe-triacetate fiber kufana nokukasilika kamalibhele. Umuzwa wokuthamba nobushelelezi nawo uyafana nowosilika kamalibhele, futhi amandla adonsela phansi athile afana nalawo kasilika kamalibhele, ngakho-ke akukho okungavamile ekomeni nosilika kamalibhele. Isici siwukuthi intengo yemicu yemvelo ibilokhu ikhuphuka eminyakeni yamuva, futhi i-triacetic acid isibe indawo enhle.

Ngakho-ke, ayikho i-drapiness engavamile kanye nosilika. Isici siwukuthi intengo yemicu yemvelo ibilokhu ikhuphuka eminyakeni yamuva, futhi i-triacetic acid isibe indawo enhle.

Amaphuzu awinile:
(1) Indwangu yesilika enamagciwane, uthuli futhi ingahlanzwa kuphela, kodwa akulula ukukhiqiza ugesi omile, akulula ukumunca uthuli emoyeni, futhi ayikho indwangu kasilika okulula ukuyidla ukushiyeka, kulula ukuyithatha. ukunakekela.
(2) Ine-thermoplasticity enhle, ukwakheka kulula ukukulungisa, uma kuqhathaniswa nempahla ye-hemp, akulula ukushwabana, nomsebenzi wokumunca umswakama welineni, ngesikhathi esifanayo, nomuzwa wokuba ndikindiki, umuzwa obandayo lapho ugqoke.
(3) Ngokunethezeka kwemicu yemvelo, lokhu kungcono kunemicu yokwenziwa. Ngesikhathi esifanayo, ukuqina kwe-viscose fiber kungcono, kodwa futhi kulula ukudaya, futhi ukusheshisa kombala kuphakeme.

4.Ukusetshenziswa kanye nokuma kwendwangu ye-acetic ekwakhiweni kwezingubo

Intengo yendwangu ye-acetic acid iyabiza, kunqunywa ukuthi kusetshenziswe izingubo ezisezingeni eliphezulu, nezinye izinto ze-satin, noma i-TR ayikwazi ukushintshwa, ngokusho kwebhande lentengo yomkhiqizo, ukubona ukuthi iwufanele yini umkhiqizo.

(1)Idizayini yemfashini --gqoka

Indwangu ye-acetic yokwenzaingubo eshelelayo, indlela ye-ace, futhi singaba nezindlela eziningi ezahlukene zokuhumusha ngokuvumelana ne-sag ehlukene yendwangu, kanye nesitayela sokuthungwa kwendwangu.

Igama Brand: Ssheena
Izithako: triacetate 82%, ethylene 18%)

(2)Idizayini yemfashini -- ibhulukwe
Noma isisho esidala: umklamo wesitayela sebhulukwe, awukwazi ukuhlukaniswa nobubanzi kanye ne-sag yendwangu. I-acetic acid impahla iyafana, naka umuzwa we-satin we-acetic acid, uzophinde ubambe umcimbi.
