Waa maxay sababta dharka acetate ay qaali u yihiin?

Labadii sano ee la soo dhaafay, naqshadeeyayaasha waxay badanaa yiraahdaan "dharka acetic acid" iyo "dharka aashitada triacetic", ka dibna waxay 3d ku dhejin doonaan dhawaaqa, "ma awoodo!" "Gacaliye geeri! Ma isticmaali karo!" Dharka noocan oo kale ah ayaa sidoo kale ah midka ugu caansan shirkadaha caanka ah ee ugu sarreeya labadii sano ee la soo dhaafay, markaa halkee ku yaal?

Isla markiiba la wadaag dhammaan noocyada kala duwan ee alaabta qalalan ee acetic acid, halkeed joogtaa, iyo habka samaynta naqshadaynta dharka, waxaanu ka dhigaynaa dharka acetic acid aad qaali u ah? Si sax ah u isticmaal.

Fiber Acetate waa nooc ka mid ah fiber-ka macmalka ah, waa walxo fibre-synthetic semi-synthetic ah, waa cellulose iyo falcelinta anhydride acetic si ay u helaan fiber acetate, ka dibna miiqan fiber cellulose acetate sameeyay. Fiber ACETATE, oo sidoo kale loo yaqaan dharka acetate, taas oo ah, dadku waxay badanaa yiraahdaan dharka acetic acid, oo loo yaqaan dharka acetate, oo sidoo kale loo yaqaan Yasha, waa homophone Shiine ah oo loogu talagalay acetate Ingiriisi.

Fiber acetate waxaa loo qaybin karaa laba nooc oo fiber acetate ah iyo saddex fiber acetate ah. Waa maxay faraqa u dhexeeya laba iyo saddex khal?

(1) Saddex khal waa nooc ka mid ah acetate, oo aan lahayn hydrolysis, iyo heerka esterification ayaa ka sarreeya. Sidaa darteed, caabbinta iftiinka iyo kulaylku waa mid xooggan, waxqabadka midabaynta ayaa liidata, iyo heerka nuugista qoyaanka (sidoo kale loo yaqaan heerka dib u soo celinta qoyaanka) ayaa hooseeya.
(2) Laba khal waa nooc ka mid ah acetate oo la sameeyay ka dib qayb ahaan hydrolysis, iyo heerka esterification ayaa ka hooseeya kan seddexda khal. Sidaa darteed, waxqabadka kuleylku uma fiicna seddex khal, waxqabadka midabaynta ayaa ka fiican seddex khal, iyo heerka nuugista qoyaanku wuxuu ka sarreeyaa saddex khal.

2.Dharka aashitada triacetic
Triacetate waxaa badanaa loo isticmaalaa naqshadeena moodada. Maanta, waxaan diirada saareynaa dharka triacetate kaas oo iska leh dharka acetic acid wanaagsan, sidaas darteed triacetate marka lagu daro qaali, qaali, qaali ~ jirka oo dhan wuxuu leeyahay faa'iidooyin ~

Triacetate, oo hoos timaada magaca SOALON, waxaa laga soo qaatay geedo yaryar oo laga beero Kanada iyo Alaska. Waa faybar macmal ah oo saafi ah, waxaa ikhtiraacay shirkadda Mitsubishi Rayon ee Japan, nooc cusub oo dabiici ah iyo teknoolojiyad sare oo isku dhafan oo dhar ah, oo leh jilicsanaan la mid ah fiilooyinka dabiiciga ah, laakiin saameynteedu waxay la mid tahay fiilooyinka macmalka ah.

Fiber Acetate ee habka esterification, heerka esterification waa in ka badan 2.7, waxaa loo yaqaan fiber triacetate, iyo dhar ka samaysan fiber triacetate waxaa loo yaqaan dhar triacetate.

Muuqaalka iyo dhalaalka fiilada triacetate waxay la mid tahay kan xariirta bulk. Dareenka jilicsanaanta iyo jilicsanaanta ayaa sidoo kale la mid ah kan Xariirka Mulberry, iyo cufis-jiidad gaar ah ayaa la mid ah kan xariirta buskudka, markaa ma jiraan wax aan caadi ahayn oo qallafsan iyo xariirta bulk. Dabeecadda ayaa ah in qiimaha fiilooyinka dabiiciga ah ay kor u kaceen sannadihii ugu dambeeyay, iyo triacetic acid waxay noqotay beddel wanaagsan.

Sidaa darteed, ma jiraan dharbaaxo aan caadi ahayn iyo xariir. Dabeecadda ayaa ah in qiimaha fiilooyinka dabiiciga ah ay kor u kaceen sannadihii ugu dambeeyay, iyo triacetic acid waxay noqotay beddel wanaagsan.

Dhibcaha guusha:
(1) Dharka xariirta ah ee leh bakteeriyada, boodhka oo kaliya waa la nadiifin karaa, laakiin ma fududa in la soo saaro koronto taagan, ma fududa in la nuugo boodhka hawada, mana jirto dhar xariir ah oo sahlan in la cuno cilladaha, si sahlan loo qaato. daryeelka.
(2) Wuxuu leeyahay heerkulbeeg wanaagsan, qaabku wuu sahlan yahay in la hagaajiyo, marka la barbardhigo walxaha hemp, ma fududa in la duuduubo, oo leh shaqada nuugista qoyaanka ee linenka, isla mar ahaantaana, oo leh dareen kabuubyo, dareemo qabow markaad xiran tahay.
(3) Raaxada fiilooyinka dabiiciga ah, tani way ka fiican tahay fiilooyinka macmalka ah. Isla mar ahaantaana, dabacsanaanta fiilada viscose ayaa ka fiican, laakiin sidoo kale way fududahay in la dheehdo, midabkuna wuu sarreeyaa.

4.Codsiga iyo meelaynta dharka acetic acid ee naqshadaynta dharka

Qiimaha dharka acetic acid waa qaali, waxaa la go'aamiyay in la isticmaalo dharka sare, oo leh satin kale, ama walxaha TR aan la bedeli karin, marka loo eego suunka qiimaha calaamadda, si loo arko haddii ay ku habboon tahay astaanta.
