Sodiyam-ka biyaha ku milmacellulose carboxymethyl, methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose iyo ethyl cellulose oo saliid ku milma ayaa dhammaantood loo isticmaalaa sida dhejisyo, burburiyayaal, agab sii dayn joogto ah oo la xakameeyey oo loogu talagalay diyaarinta afka, wakiilada sameeya filimka dahaarka, agabka kaabsal iyo wakiilada joojinta ayaa loo isticmaalaa daawooyinka kaabsal. Marka la eego adduunka, dhowr shirkadood oo ajnabi ah oo caalami ah (Shin-Etsu Japan, Dow Wolfe iyo Ashland Cross Dragon) ayaa ogaaday suuqa mustaqbalka ee weyn ee cellulose-ka dawooyinka ee Shiinaha, iyagoo kordhinaya wax soo saarka ama isku darka, waxayna kordhiyeen dadaalkooda ku aaddan arrintan. gudaha codsiga. Dow Wolfe waxay ku dhawaaqday inay xoojin doonto diiradda ay saarayso diyaarinta, maaddooyinka iyo baahida suuqa diyaarinta dawooyinka Shiinaha, cilmi-baaristeeda la dabaqay waxay sidoo kale ku dadaali doontaa inay u soo dhawaato suuqa. Waaxda Dow Chemical Wolff Cellulose iyo Colorcon Corporation ee Mareykanka ayaa aasaasay isbahaysi sii-deyn ah oo joogto ah oo la xakameeyey oo heer caalami ah, iyadoo in ka badan 1,200 oo shaqaale ah ay ku sugan yihiin 9 magaalo, 15 hay'adood oo hanti ah iyo 6 shirkadood oo GMP ah, tiro badan oo xirfadlayaal cilmi-baaris oo Applied ah ayaa u adeega macaamiisha qiyaastii 160 waddan. Ashland waxay saldhigyo wax soo saar ku leedahay Beijing, Tianjin, Shanghai, Nanjing, Changzhou, Kunshan iyo Jiangmen, waxayna maalgelisay saddex xarumood oo cilmi-baaris farsamo ah oo ku yaal Shanghai iyo Nanjing.
Sida laga soo xigtay tirakoob laga soo xigtay mareegaha China Cellulose Association, sannadkii 2017, wax soo saarka gudaha ee cellulose ether wuxuu ahaa 373,000 tan, mugga iibkuna wuxuu ahaa 360,000 tan. Sannadkii 2017, mugga iibka dhabta ah ee ionic CMC wuxuu ahaa 234,000 tan, koror dhan 18.61% sannadkii, iyo mugga iibka ee non-ionicCMCwaxay ahayd 126,000 oo tan, koror dhan 8.2% sanadba sanadka ka dambeeya. Marka laga soo tago HPMC (heerka agabka dhismaha), alaabada aan ionic ahayn, HPMC (heerka daawada),HPMC(heerka cuntada),HEC, HPC, MC, HEMCiwm. ayaa ka soo horjeeday isbeddelka, wax soo saarkooda iyo iibkooduna wuu sii kordhay. Ether-ka cellulose-ka ee gudaha ayaa si xawli ah u koray in ka badan toban sano, wax soo saarkiisuna wuxuu noqday kii ugu horreeyay adduunka. Si kastaba ha ahaatee, wax soo saarka shirkadaha ether-ka cellulose-ka badankood waxaa inta badan loo isticmaalaa warshadaha dhexe iyo kuwa hoose, qiimaha dheeraadka ahna ma sarreeyo.
Waqtigan xaadirka ah, inta badan shirkadaha gudaha ee cellulose ether waxay ku jiraan xilliga muhiimka ah ee isbeddelka iyo casriyeynta. Waa inay sii wadaan inay kordhiyaan dadaallada cilmi-baarista iyo horumarinta alaabta, si joogto ah u kobciyaan noocyada wax soo saarka, si buuxda uga faa'iidaystaan Shiinaha, oo ah suuqa ugu weyn adduunka, iyo inay kordhiyaan dadaallada lagu horumarinayo suuqyada shisheeye, si shirkaduhu si dhakhso ah u dhammaystiraan isbeddelka iyo casriyeynta, u galaan qaybta dhexe iyo tan sare ee warshadaha, oo ay u gaaraan horumar wanaagsan oo cagaaran.
