I-sodium encibilikayo emanzinii-carboxymethyl cellulose, i-methyl cellulose, i-hydroxypropyl methyl cellulose, i-hydroxypropyl cellulose, i-hydroxyethyl cellulose kanye ne-oil-soluble ethyl cellulose konke kusetshenziswa njengeZinamatheliso, ama-disintegrants, izinto zokukhulula eziqhubekayo nezilawulwayo zokulungiswa komlomo, ukumboza ama-agent okwenza ifilimu, izinto ze-capsule kanye nama-ejenti aqeda amandla asetshenziswayo. Uma sibheka umhlaba, izinkampani eziningana zakwamanye amazwe zakwamanye amazwe (Shin-Etsu Japan, Dow Wolfe kanye ne-Ashland Cross Dragon) ziye zaqaphela imakethe enkulu yesikhathi esizayo ye-cellulose yemithi e-China, noma ukwandisa ukukhiqizwa noma ukuhlanganisa, futhi zandise imizamo yazo kulo mkhakha. okokufaka kohlelo lokusebenza ngaphakathi. I-Dow Wolfe imemezele ukuthi izoqinisa ukugxila kwayo ekwakhiweni, izithako kanye nesidingo semakethe yaseShayina yokulungiselela imithi, futhi ucwaningo lwayo olusetshenzisiwe luzolwela ukusondela emakethe. I-Dow Chemical Wolff Cellulose Division kanye ne-Colourcon Corporation yase-United States basungule umfelandawonye wokwakhiwa kokukhululwa okuqhubekayo futhi olawulwayo emhlabeni wonke, onabasebenzi abangaphezu kuka-1,200 emadolobheni angu-9, izikhungo zempahla eziyi-15 kanye nezinkampani eziyisi-6 ze-GMP, isibalo esikhulu sochwepheshe bocwaningo Olusetshenziswayo abasebenzela amaklayenti cishe emazweni ayi-160. I-Ashland inezisekelo zokukhiqiza e-Beijing, e-Tianjin, e-Shanghai, e-Nanjing, e-Changzhou, e-Kunshan nase-Jiangmen, futhi itshale imali ezikhungweni zocwaningo lwezobuchwepheshe ezintathu e-Shanghai nase-Nanjing.
Ngokwezibalo ezivela kuwebhusayithi ye-China Cellulose Association, ngo-2017, ukukhiqizwa kwasekhaya kwe-cellulose ether kwakungamathani angu-373,000, futhi umthamo wokuthengisa wawungamathani angu-360,000. Ngo-2017, umthamo wangempela wokuthengisa we-ionic CMC wawungamathani angama-234,000, ukukhuphuka ngo-18.61% unyaka nonyaka, kanye nevolumu yokuthengisa ye-non-ionic.I-CMCbekungamathani ayi-126,000, okuwukukhula ngo-8.2% unyaka nonyaka. Ngaphezu kwe-HPMC (ibanga lezinto zokwakha), imikhiqizo engeyona i-ionic, i-HPMC (ibanga lezemithi),I-HPMC(ibanga lokudla),HEC, HPC, MC, HEMC, njll. baye bawuqeda lo mkhuba futhi ukukhiqizwa nokuthengisa kwabo kuye kwaqhubeka kwanda. I-ether ye-cellulose yasekhaya ikhule ngokushesha iminyaka engaphezu kweyishumi, futhi ukukhishwa kwayo kube ngowokuqala emhlabeni. Kodwa-ke, imikhiqizo yezinkampani eziningi ze-cellulose ether isetshenziswa ikakhulukazi emasimini aphakathi nendawo aphansi embonini, futhi inani elingeziwe aliphezulu.
Njengamanje, amabhizinisi amaningi asekhaya e-cellulose ether asesikhathini esibucayi soshintsho nokuthuthukiswa. Kufanele baqhubeke nokwandisa imizamo yocwaningo nentuthuko yomkhiqizo, ngokuqhubekayo bacebise izinhlobo zemikhiqizo, basebenzise ngokugcwele iShayina, imakethe enkulu kunazo zonke emhlabeni, futhi bakhulise imizamo yokuthuthukisa izimakethe zakwamanye amazwe, ukuze amabhizinisi akwazi ukuqeda ngokushesha uguquko nokuthuthukisa, angene emkhakheni ophakathi nendawo nosezingeni eliphezulu wemboni, futhi azuze intuthuko enempilo neluhlaza.
