Qeybta QurbahaMa yihiin polymers-ka biyaha-soluble ah oo ka soo baxay celyulose, polymmer ugu badan ee dabiiciga ah. In ka badan 60 sano, alaabooyinkan kala duwan waxay door muhiim ah ka ciyaareen codsiyada martigelinta, ka soo baxa wax soo saarka dhismaha, dhoobada iyo rinjiyeynta cuntooyinka, waxyaabaha la isku qurxiyo iyo dawooyinka.
Wixii alaabada dhismaha ah, kakaanka qoryaha qalliinka waxay u dhaqmaan sidii dhumucyo, dabinno, abuurasho filim iyo wakiillo biyo-haynta biyaha. Waxay sidoo kale u shaqeeyaan sidii gaanta gaanta, saliidaha, saliidaha, aruurinta difaaca iyo emulsifers. Intaa waxaa sii dheer, xalka aqueol ee qalliinka unugyada qaarkood ee gecally gel, waa hanti gaar ah oo door muhiim ah ka ciyaara la yaabka leh
codsiyada kala duwan. Isku-darkan qiimaha leh ee guryaha laguma helin polymer kale oo biyo ah.
Xaqiiqda ah in sifooyin badan oo wax laga ogaado si isku mid ah loo joogo oo inta badan ay ku dhaqmaan isku darka waxay noqon kartaa faa'iido dhaqaale oo saxeexan. Codsiyo badan, laba, saddex ama in kabadan oo maaddooyin ama in ka badan oo ka kooban ayaa looga baahan doonaa inay isla shaqeeyaan isla markaana ay sameeyaan hal shey oo keli ah oo shey ah oo ether ah. Intaa waxa u dheer, anshax-gacmeedyada unugyada ayaa ah kuwo aad u hufan, badiyaa
Soosaarista waxqabadka ugu habboon ee foosha hoose ee ka badan kuwa looga baahan yahay polymers kale oo biyo-ku-milicsan.
Kiimikooyinka Dhismaha Dhismaha DOW waxay bixiyaan noocyo badan oo ka mid ah wax soosaarka kaadida, oo ay ku jiraan methyl cellulose, hydroxyetyl cell-ka cell-ka iyo carboxmethyl cellulose. Qormada celkyl ee methers-ka waxaa si ballaaran loogu isticmaalaa codsiyo badan oo dhismaha iyo warshadaha dhismaha ah.
Chemistry of Ethers
Ganacsigeenna ayaa bixiya ka-yeelashada kabitaanka unugyada unugyada ah afar nooc oo aasaasi ah:
1.hydroxyetylylyl bylulose (hemc / mHEC)
2.hydroxypylpyl bylule (HPMC, MC)
3.hydroxyetylylule (HEC)
4.Carxy methyl bylulose (cmc)
Labada noocba waxay leeyihiin laf-dhabarka polymbie ee cellulose, karbohaydrayt dabiici ah oo ka kooban qaab dhismeedka aasaasiga ah ee unugyada ashxanka. Intii lagu gudajiray soo-saaridda ee anshax-gacmeedyada, fiilooyinka unugyada ayaa lagu kululeeyaa xalka caustic ah, oo loo jeediyo, iyo in ethylolne oxide, oo dhalisay hydroxypropyl ama hydroxytyl bylulose, siday u kala horreeyaan. Shayga fal-celinta ee la soo rogay waa la nadiifiyaa oo looxeeyaa oo ku yaal budo ganaax ah, isku mid ah.
Alaabada gaarka loo leeyahay ayaa sidoo kale loo sameeyay si ay u buuxiyaan shuruudaha warshadaha gaarka loo leeyahay.
Waxsoosaarkayaga laf-dhabarka ah ee loo yaqaan 'cell ether' Nooca badeecada lagu sameeyo flo-ga kaas oo qaabeeya. Inta badan codsiyada qalalan ee qalalan, budada aan la daaweyn ayaa sida caadiga ah loo isticmaalaa, halka codsiyada isku-darka-diyaarsan, kaas oo ay ku dari karaan budada unugyada ee si toos ah loogu daro biyaha, budada dusha sare-dusha ah ama qaababka granular ayaa la door bidaa.
Guryaha guud
Guryaha guud ee caan ku ah anshaxayaga unugyada ah ayaa halkan ku taxan. Alaabada shaqsiyadeed waxay soo bandhigaan guryahaas si ay u kala baxaan heerar kala duwan oo laga yaabo inay lahaato
additional properties desirable for specific applications. For more information, email at sales@kimachemical.com .
