Ngaba ngokwenene uyazi ngamalaphu e-acetate?
Ifayibha ye-acetate, ephuma kwi-acetic acid kunye neselulosi ngokusebenzisa i-esterification, yintsinga eyenziwe ngumntu elinganisa ngokusondeleyo iimpawu zobunewunewu zesilika.Obu buchwephesha belaphu buphambili buvelisa ilaphu elinemibala eqaqambileyo, inkangeleko ekhazimlayo, kunye nemvakalelo egudileyo, ekhululekile.Iimpawu zayo zekhemikhali kunye nezomzimba zenza ukuba ibe yinto eguquguqukayo kunye neyomelele kwizicelo ezahlukeneyo.
Ngokumalunga neepropati zeekhemikhali, i-acetate fiber ibonisa ukuchasana okuphawulekayo kuzo zombini i-alkaline kunye ne-acidic agents, okwenza kube lukhetho oluqinileyo kwiindawo ezininzi.Noko ke, ukudaya kwayo kulucelomngeni olukhethekileyo, njengoko iidayi zecellulose eziqhelekileyo zinonxulumano olulinganiselweyo kwimicu yeacetate, nto leyo eyenza kube nzima ukuyidaya.
Iimpawu ezibonakalayo zefiber ye-acetate ziqhubela phambili ukubhenela kwayo.Ngokuzinza kakuhle kwe-thermal, i-fiber inokumelana namaqondo obushushu ukuya kwi-185 ° C ngaphambi kokufikelela kwiqondo lokushisa lokutshintsha kweglasi, kwaye malunga ne-310 ° C ngaphambi kokunyibilika.Ngelixa ibonisa ukucutheka okuphantsi emanzini abilayo, unyango oluphezulu lobushushu lunokuchaphazela amandla kunye neglosi, lufuna ukuphathwa ngononophelo ukugcina ingqibelelo yalo.
Ngokucacileyo, ifayibha ye-acetate ikwanazo nokunwebeka okuhle ngokwentelekiso, ngokufana nesilika kunye noboya, isongeza ekuguquguqukeni nasekuthuthuzelekeni kwayo.
Ukuqonda iimpawu ezizodwa zefiber yeacetate kubalulekile ekwandiseni amandla ayo kumashishini ahlukeneyo, ukusuka kwifashoni kunye namalaphu ukuya kuhluzo nangaphaya.Ukukwazi kwayo ukuxelisa iimpawu ezitofotofo zesilika ngelixa inika iingenelo ezahlukileyo ngokwemichiza kunye neempawu zomzimba ziyenza ibe yinto efunwayo kuluhlu olubanzi lwezicelo.Njengoko itekhnoloji kunye nokuveliswa kwezinto ezintsha kuqhubeka ukuqhubela phambili kwimveliso yelaphu, i-acetate fiber ime njengobungqina bobuchule kunye nokuguquguquka kweentsinga ezenziwe ngumntu.
