ACETATE POLY ANTI-STATIC, FABRIC KA ILAALINTA MAQAARKA KA-hortagga ultraviolet ee lebbiska AC9218
Ma waxaad sidoo kale raadinaysaa mid?
Shaygan Habka midabaynta cusub, dusha sare ee dharku waa xariir, dhalaaliddu waa mid jilicsan sida xariirta dhabta ah, dareenka dhogorta leh, xirashada, ilaalinta ayaa ka baxsan xariirka dhabta ah, oo leh nuugista qoyaanka, sii deynta qoyaanka, xirashada raaxada leh, waa maaddada wajiga neefsashada dhabta ah, caabbinta laalaabku waa wanaagsan tahay, fududahay in la maareeyo, isla mar ahaantaana waxay leedahay shaqada ilaalinta maqaarka ee dabiiciga ah ee ka hortagga ultraviolet.
Qaab dhismeedka fiber acetate fiber dusha sare ee dhererka dhererka waa siman yahay oo lebbisan, oo leh gogol cad;Sida laga arki karo qaabka isgoysyada, fiber-ku ma laha qaab-dhismeed maqaar ah, kaas oo u qaabaysan caleen alfalfa, oo leh durugsan oo siman iyo dhowr seerations gacmeed.
Astaamaha astaamaha kiimikada fiber acetate
1. Iska caabin alkali ah
Wakiilka daciifka ah ee alkaline ma dhaawicin fiber acetate asal ahaan, iyo heerka miisaanka luminta fiber-ka ayaa ahaa mid aad u yar.Marka ay la kulanto alkali xooggan, gaar ahaan fiber diacetate, way fududahay in la deacetylate, taas oo keenta miisaan lumis, xoogga iyo modules hoos u dhaca.Sidaa darteed, qiimaha pH ee xalka loogu talagalay daaweynta acetate cellulose waa inuusan ka badnayn 7.0.Marka la eego xaaladaha dhaqidda caadiga ah, waxay leedahay iska caabin xoog leh oo koloriin ah waxaana sidoo kale lagu nadiifin karaa qalalan tetrachlorethylene.
2. Iska caabinta dareerayaasha organic
Cellulose acetate waxay si buuxda ugu milmay acetone, DMF iyo glacial acetic acid, laakiin aan lagu milmin ethanol iyo tetrachlorethylene.Marka loo eego sifooyinkaas, acetone waxaa loo isticmaali karaa sida dareeraha wareega ee fiber acetate, iyo tetrachlorethylene waxaa loo isticmaali karaa in lagu qalajiyo maro fayraska acetate nadiif ah.
3. caabbinta aysiidhka
Fiber Acetic acid waxa uu leeyahay xasilooni aashito wanaagsan, iyo sulfuric acid, hydrochloric acid iyo nitric acid ma saameyn doonto xoogga, dhalaalka iyo fidinta fiberka gudaha xad gaar ah.Laakin waxa lagu milmi karaa asiidh sulfuric ah oo xoogaysan, hydrochloric acid iyo nitric acid.
4. Midabaynta
Inkasta oo acetate cellulose laga soo qaatay cellulose, inta lagu jiro habka esterification, qayb weyn oo ka mid ah kooxaha hydroxyl polar ee giraanta gulukooska ee cellulose ayaa lagu beddelaa kooxaha acetyl.Sidaa darteed, midabada sida caadiga ah loo isticmaalo dheehaynta fiber cellulose waxay ku dhowdahay wax xiriir ah oo loogu talagalay acetate cellulose wayna adagtahay in la midabeeyo.Midabada ugu habboon ee loo yaqaan 'acetate fiber' waa midabyo kala firdhiya oo leh miisaan yar oo molecular ah iyo heerka midabaynta la midka ah.
Fiber acetate ama dharka lagu rinjiyeeyay midabyo kala firdhiyey ayaa leh midab dhalaalaya, saameyn heer sare ah, heerka daalka midabka sare, midabka midabka sare iyo chromatography dhamaystiran.
