Kala firdhi Jaalle 241 CAS 83249-52-9 hordhac

Jaallaha kala firdhiso 241 waa dheeha synthetic oo inta badan loo isticmaalo in lagu dheehdo fiilooyinka, gaar ahaan kuwa loo yaqaan 'synthetic fibers'.

Habka wax soo saarka ee kala firdhiso Jaallaha 241 guud ahaan waxa ka mid ah tillaabooyinka soo socda:

1. Diyaarinta alaabta bilawga ah: Marka loo eego qaabka iyo habka isku-dhafka jaalaha ah ee kala firdhiyey 241, alaabta bilawga ah waxaa lagu farsameeyaa falcelinta kiimikada. Qalabkan bilowga ah waxaa ka mid noqon kara aniline, amino acids, iwm.

2. Falanqaynta falcelinta: Agabka bilawga ah ee isku xidhka waxa lagu farsameeyaa falcelinta xeryahooda kale ee loo baahan yahay. Talaabadani guud ahaan waxa ay ku lug leedahay falcelinta isku xidhka kiimikaad, sida amidation, acetylation, iwm

3. Crystallization iyo nadiifinta: Badeecada la isku daray waxay caadi ahaan u jirtaa qaabka xal waxayna u baahan tahay in la nadiifiyo oo la nadiifiyo si loo hagaajiyo nadiifinta. Talaabadani guud ahaan waxa ay ku lug leedahay xakamaynta arrimaha sida heerkulka, xulashada dareeraha, iwm., si loo miireeyo alaabta loogana saaro wasakhda.

4. Qalajinta iyo burburinta: Alaabta la sifeeyay waxay u baahan tahay in la qalajiyo oo la miiriyo si loo helo badeecada jaalaha ah ee 241 ee la rabo. Tallaabadan waxaa lagu gaari karaa in la qalajiyo badeecada heerkul hoose iyo faaruq, oo la burburiyo iyada oo la adeegsanayo qalab ku habboon si loo helo cabbirka walxaha la rabo iyo qaab-dhismeedka.

5. Tijaabada iyo falanqaynta: Waa lagama maarmaan in la sameeyo kormeer tayo leh iyo falanqayn ku saabsan jaalaha kala firdhiyey ee 241 ee laga helay wax soo saarka si loo hubiyo in tayada alaabadu ay buuxisay shuruudaha. Hababka ogaanshaha inta badan la isticmaalo waxaa ka mid ah infrared spectroscopy, resonance magnetka nukliyeerka, iwm.
