Soodhiyam biyo-milmi lehcarboxymethyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose iyo saliid- milmi ethyl cellulose oo dhan waxaa loo isticmaalaa sida Xabagta, disintegrants, waarta iyo qalabka sii daayo la xakameeyey ee diyaarinta afka, daahan wakiilada film-samaynta, alaabta kaabsoosha iyo wakiilada laalista waxaa loo isticmaalaa in farmasiyada. Marka la eego adduunka, dhowr shirkadood oo caalami ah oo caalami ah (Shin-Etsu Japan, Dow Wolfe iyo Ashland Cross Dragon) ayaa xaqiiqsaday suuqa mustaqbalka weyn ee cellulose-ka dawooyinka ee Shiinaha, ama kordhinta wax soo saarka ama isku-dhafka, waxayna kordhiyeen dadaalkooda goobtan. gelinta codsiga gudaha. Dow Wolfe ayaa shaaca ka qaaday in ay xoojin doonto diiradda saarideeda qaabeynta, maaddooyinka iyo baahida suuqa diyaarinta dawooyinka Shiinaha, cilmi baaristeeda la dabaqay ayaa sidoo kale ku dadaali doonta in ay ku soo dhawaato suuqa. Qaybta Dow Chemical Wolff Cellulose iyo Colorcon Corporation ee Maraykanka ayaa aasaasay isbahaysiga qaabaynta sii deynta joogtada ah oo la xakameeyey oo heer caalami ah, oo leh in ka badan 1,200 shaqaale ah oo ku sugan magaalooyinka 9, xarumaha 15 ee hantida iyo shirkadaha 6 GMP, tiro badan oo xirfadlayaal cilmi-baaris ah oo la dabaqay ayaa u adeega macaamiisha ku dhawaad 160 waddan. Ashland waxay ku leedahay saldhigyo wax soo saar oo ku yaal Beijing, Tianjin, Shanghai, Nanjing, Changzhou, Kunshan iyo Jiangmen, waxayna maalgelisay saddex xarumood oo cilmi baaris ah oo ku yaal Shanghai iyo Nanjing.
Marka loo eego tirokoobyada shabakadda Shiinaha ee Cellulose Association, 2017, wax soo saarka gudaha ee ether-ka cellulose wuxuu ahaa 373,000 tan, mugga iibkuna wuxuu ahaa 360,000 oo tan. 2017, mugga iibka dhabta ah ee ionic CMC wuxuu ahaa 234,000 ton, korodhka 18.61% sanad kasta, iyo mugga iibka ee aan-ionic ahayn.CMCwuxuu ahaa 126,000 ton, korodhka 8.2% sanadba sanadka ka dambeeya. Marka lagu daro HPMC (darajada walxaha dhismaha), alaabada aan-ionic ahayn, HPMC (darajada dawooyinka),HPMC(heerka cuntada),HEC, HPC, MC, HEMC, iwm ayaa dabada ka riixay is-beddelka, wax-soo-saarkooda iyo iibkooduna wuu sii kordhay. Eter cellulose-ka gudaha ayaa si xawli ah u koray in ka badan toban sano, wax soo saarkiisuna wuxuu noqday kii ugu horreeyay ee adduunka. Si kastaba ha noqotee, badeecadaha inta badan shirkadaha ether-ka cellulose ayaa inta badan loo isticmaalaa meelaha dhexe iyo kuwa hoose ee warshadaha, qiimaha lagu daray ma aha mid sarreeya.
Waqtigan xaadirka ah, badi ganacsiyada ether-ka gudaha ee cellulose waxay ku jiraan xilliga muhiimka ah ee isbeddelka iyo hagaajinta. Waa inay sii wadaan kordhinta cilmi baarista iyo dadaallada horumarineed ee wax soo saarka, si joogto ah u kobciyaan noocyada badeecadaha, si buuxda uga faa'iideystaan Shiinaha, oo ah suuqa ugu weyn adduunka, iyo inay kordhiyaan dadaallada lagu horumarinayo suuqyada shisheeye, si shirkaduhu ay si dhakhso ah u dhammaystiraan isbeddelka iyo tayeynta, galaan bartamaha iyo dhamaadka-dhamaadka sare ee warshadaha, una gaaraan horumar wanaagsan iyo cagaar.
