Iindaba - Kutheni amalaphu e-acetate ebiza kakhulu

Kwiminyaka emibini edlulileyo, abaqulunqi bahlala besithi "ilaphu le-acetic acid" kunye "nelaphu le-asidi ye-triacetic", kwaye emva koko baya ku-3d loop malunga nesandi, "abanakukwazi!" "Kufa othandekayo! Awukwazi ukuyisebenzisa!" Olu hlobo lwelaphu lukwayinto eyintandokazi yeenkampani zodidi oluphezulu kwiminyaka emibini edlulileyo, ke ziphi?

Yabelana ngazo zonke iintlobo zeempahla ezomileyo ze-acetic acid ngoko nangoko, uphi na, kwaye kwinkqubo yokwenza uyilo lwempahla, senza amalaphu e-acetic acid abiza kakhulu? Yisebenzise ngokufanelekileyo.

1.Acetic acidilaphu
Ifayibha ye-acetate luhlobo lwefiber eyenziweyo, i-semi-synthetic fiber material, i-cellulose kunye ne-acetic anhydride reaction yokufumana i-fiber acetate, emva koko i-spun cellulose i-acetate fiber yenziwe. I-ACETATE fiber, eyaziwa ngokuba yilaphu le-acetate, oko kukuthi, abantu bahlala bethetha ilaphu le-acetic acid, eyaziwa ngokuba yilaphu le-acetate, eyaziwa ngokuba yi-Yasha, yi-homophone yaseTshayina ye-acetate yesiNgesi.

I-acetate fiber inokwahlulwa ibe ziintlobo ezimbini zefiber ye-acetate kunye ne-acetate fiber ezintathu. Uthini umahluko phakathi kweviniga ezimbini nezithathu?

(1) Iviniga emithathu luhlobo lwe-acetate, ngaphandle kwe-hydrolysis, kwaye iqondo layo le-esterification liphezulu. Ke ngoko, ukukhanya kunye nokumelana nobushushu kunamandla, ukusebenza kokudaya kumbi, kwaye inqanaba lokufunxa ukufuma (ekwabizwa ngokuba linqanaba lokubuyisela ukufuma) liphantsi.
(2) Iviniga ezimbini luhlobo lweacetate eyenziwe emva kwe-hydrolysis engaphelelanga, kwaye iqondo layo le-esterification lingaphantsi kunelo leviniga emithathu. Ke ngoko, ukusebenza kokufudumeza akulunganga njengeviniga ezintathu, ukusebenza kokudaya kungcono kuneviniga emithathu, kwaye izinga lokufunxa ukufuma liphezulu kuneviniga emithathu.

Ilaphu le-2.Triacetic acid
I-Triacetate ihlala isetyenziswa kuyilo lwethu lwefashoni. Namhlanje, sigxininisa kwilaphu le-triacetate lelaphu elihle le-acetic acid, ngoko ke i-triacetate ukongeza kwixabiso eliphezulu, ixabiso, ixabiso eliphezulu ~ umzimba wonke unezibonelelo ~

I-Triacetate, phantsi kwegama elithi SOALON, lithatyathwe kwiiconifers ezikhule eCanada naseAlaska. Yifiber esulungekileyo esemi-artificial, eyilwe yiNkampani yaseJapan iMitsubishi Rayon, uhlobo olutsha lwamalaphu endalo kunye nobuchwepheshe obuphezulu, obuthambileyo obufana nolweentsinga zendalo, kodwa isiphumo salo sinokuthelekiswa neentsinga ezenziweyo.

I-acetate fiber kwinkqubo ye-esterification, iqondo le-esterification lingaphezulu kwe-2.7, libizwa ngokuba yi-triacetate fiber, kunye nelaphu elenziwe nge-triacetate fiber libizwa ngokuba yilaphu le-triacetate.

3. I-PK enemicu yendalo kunye nemicu eyenziwe ngabantu

Inkangeleko kunye nokubengezela kwefiber ye-triacetate iyafana nesilika ye-mulberry. Imvakalelo yokuthamba kunye nokuguda ikwafana nesilika ye-mulberry, kwaye ubunzima bayo obuthile buyafana nobobusilika be-mulberry, ngoko ke akukho nto ingaqhelekanga ekomeni kunye nesilika ye-mulberry. Uphawu kukuba ixabiso leefayili zendalo liye lanyuka kwiminyaka yamuva nje, kwaye i-triacetic acid ibe yindawo efanelekileyo.

Ke ngoko, akukho drapiness engaqhelekanga kunye nesilika. Uphawu kukuba ixabiso leefayili zendalo liye lanyuka kwiminyaka yamuva nje, kwaye i-triacetic acid ibe yindawo efanelekileyo.

Amanqaku aphumeleleyo:
(1) Ilaphu lesilika kunye neebhaktheriya, uthuli kwaye inokosula kuphela, kodwa akukho lula ukuvelisa umbane static, akukho lula ukufunxa uthuli emoyeni, kwaye akukho ilaphu isilika lula ukutya iintsilelo, kulula ukunyamekela.
(2) Ine-thermoplasticity elungileyo, imilo kulula ukuyilungisa, xa kuthelekiswa nezinto ze-hemp, akukho lula ukushwabana, kunye nomsebenzi wokufunxa ukufuma kwelinen, kwangaxeshanye, ngemvakalelo yokuba ndindisholo, imvakalelo ebandayo xa unxibe.
(3) Ngokuthuthuzeleka kwemicu yendalo, oku kungcono kunemicu eyenziweyo. Kwangaxeshanye, i-elasticity ye-viscose fiber ingcono, kodwa kulula ukuyidaya, kwaye ukukhawuleza kombala kuphezulu.

4.Ukusetyenziswa kunye nokubekwa kwelaphu le-acetic acid kuyilo lwempahla

Ixabiso lelaphu le-acetic acid liyabiza, kugqitywe ukuba kusetyenziswe iimpahla eziphezulu, kunye nezinye i-satin, okanye izinto ze-TR azikwazi ukutshintshwa, ngokwebhanti yexabiso le-brand, ukubona ukuba ifanelekile kwi-brand.

(1)Uyilo lwefashoni --nxiba

ilaphu Acetic acid ukwenzailokhwe etyibilikayo, yindlela ye-ace, kwaye sinokuba neendlela ezininzi ezahlukeneyo zokutolika ngokwesagi eyahlukileyo yelaphu, kunye nesimbo sokuthungwa kwelaphu.

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

(2)Uyilo lwefashoni -- ibhulukhwe
Okanye ilizwi elidala: uyilo lwesitayela sebhulukhwe, ayinakuhlukaniswa nobubanzi kunye ne-sag yelaphu. I-acetic acid imathiriyeli iyafana, nikela ingqalelo kwimvakalelo ye-satin ye-acetic acid, nayo iya kuhuka isenzeko.
