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 kuyafana 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 inokucocwa kuphela, kodwa akukho lula ukuvelisa umbane omileyo, akukho lula ukufunxa uthuli emoyeni, kwaye akukho ilaphu lesilika kulula ukuyidla iintsilelo, kulula ukuyithatha. Khathalela i.
(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 kuqhaga isenzeko.
