I-Cellulose Ether uhlobo lwe-polymer yemvelo ethathwe khona, enezimpawu zokufakwa kwe-emulsation nokumiswa. Phakathi kwezinhlobo eziningi, i-HPMC yiyona enomphumela ophakeme kakhulu kanye nokusetshenziswa kabanzi, futhi okuphumayo kwawo kuyanda ngokushesha.
Eminyakeni yamuva nje, ngenxa yokukhula komnotho wezwe, ukukhiqizwa kweCellose Ether ezweni lami kukhule unyaka nonyaka. Ngasikhathi sinye, ngokuthuthukiswa kwesayensi yasekhaya nezobuchwepheshe, izithambiso eziphakeme kakhulu ze-cellulose zidinga ukuthi inani elikhulu lokungeniswa manje selivele lakhiwe, futhi umthamo wokuthekelisa we-avent of cellulose uyaqhubeka nokwanda. Idatha ikhombisa ukuthi kusukela ngoJanuwari kuya ku-Novemba 2020, ukuthunyelwa kwama-ether ethertose ether ether, kwandiswa unyaka nonyaka wevolumu yangelinye unyaka ka-2019.
I-Cellulose Ether ithintwa amanani entengo kakotini aphezulu:
Izinto zokusetshenziswa eziphambili ze-cellulose ether zifaka imikhiqizo yezolimo nezamahlathi kufaka phakathi ukotini ocwengekile kanye nemikhiqizo yamakhemikhali kufaka phakathi i-propelene oxide. Izinto ezivuthiwe zikakotini ezicwengiwe zingamatshe okukotini. Izwe lami linokukhiqizwa okuchichimayo ukotini, futhi izindawo zokukhiqiza zekotini zigxile kakhulu eShandong, uXinjiang, Hebei, Jiangsu nezinye izindawo. Ama-Cotton Linters agcwele kakhulu futhi anikezwa kaningi.
Ukotini uthatha ingxenye enkulu enkulu yezolimo yezolimo yezolimo, futhi intengo yayo ithinteke yizici eziningi ezinjengezimo zemvelo nokunikezwa kwamanye amazwe kanye nesidingo. Ngokufanayo, imikhiqizo yamakhemikhali efana ne-propelene oxide kanye ne-methyl chloride nangokuthintwa amanani entengo kawoyela aphesheya. Njengoba izinto eziluhlaza ze-akhawunti ze-Akhawunti enkulu ngengxenye enkulu ekwakheni izindleko ze-cellulose ether, ukuguquguquka kwamanani entengo eluhlaza athinta ngqo intengo yokuthengisa ye-cellulose ether.
Ephendula ingcindezi yezindleko, abakhiqizi be-cellulose ether bavame ukudlulisela ingcindezi yezimboni ezansi, kepha umphumela wokudlulisa uthintwa yinkimbinkimbi yemikhiqizo yezobuchwepheshe, ukwehluka komkhiqizo kanye nenani lentengo yomkhiqizo. Imvamisa, amabhizinisi anezithiyo eziphakeme zobuchwepheshe, izigaba zomkhiqizo ocebile, nenani eliphakeme eliphakeme linezinzuzo ezinkulu, namabhizinisi azogcina izinga elizinzile lenzuzo enkulu; Ngaphandle kwalokho, amabhizinisi adinga ukubhekana nengcindezi yezindleko ezinkulu. Ngaphezu kwalokho, uma imvelo yangaphandle ingazinzi futhi uhla lokushintshashintsha komkhiqizo lukhulu, izinkampani ezibonakalayo ezikhuphukayo ze-Upstream zizimisele ngokwengeziwe ukukhetha amakhasimende aphansi ngokukhiqiza futhi anciphise izingozi. Ngakho-ke, lokhu kunciphisa ukuthuthukiswa kwamabhizinisi amancane we-cellulose ether ngezinga elithile.
Isakhiwo semakethe esiphansi:
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imakethe ye-DownTream Dem shows izokhula ngokufanele. Ngasikhathi sinye, ubukhulu bezicelo ezaphansi komfula kulindeleke ukuthi baqhubeke nokwandisa, futhi ukufunwa phansi kwehle kuzogcina ukukhula okuqhubekayo. Esakhiweni semakethe esiphansi se-cellulose ether, izinto zokwakha, ukuhlola uwoyela, ukudla kanye nezinye izinkambu ezithatha isikhundla esikhulu. Phakathi kwazo, umkhakha wokwakha wokwakha yimakethe yabathengi enkulu kunazo zonke, afaka imali engaphezu kwama-30%.
Imboni yezokwakha iyinkambu yabathengi enkulu kunazo zonke yemikhiqizo ye-HPMC:
Embonini yezokwakha, imikhiqizo ye-HPMC idlala indima ebalulekile eBonding kanye nokugcinwa kwamanzi. Ngemuva kokuxubana inani elincane le-HPMC ngodaka kasimende, lungakhulisa amandla okubonakala, ukushesha futhi shear wamandla kasimende, udaka, i-binder, njll, ukwenza ngcono ukusebenza kwezinto zokwakha, ukuthuthukisa ikhwalithi yokwakha. Ngaphezu kwalokho, i-HPMC ibuye ibe ngumthengisi obalulekile wokukhiqiza kanye nokuhamba ngokhonkolo kwezohwebo, okungakhiya amanzi futhi athuthukise i-Rheology kakhonkolo. Njengamanje, i-HPMC ingumkhiqizo oyinhloko we-cellulose ether esetshenziswa ekwakheni uphawu lwezinto zokwakha.
Imboni yezokwakha imboni yensika ebalulekile yomnotho wezwe lakuleli. Imininingwane ikhombisa ukuthi indawo yokwakha yokwakhiwa kwezindlu inyuke kusuka kumamitha-skwele angama-78 billion skwele ngonyaka ka-2010 kuya ku-14.42 billion amamitha-skwele ngonyaka we-2019, okuvuse kakhulu ukukhula kwemakethe ye-cellulose ether.
Ukuchuma okuphelele komkhakha wezezakhiwo kuye kwaphindeka kabusha, futhi indawo yokwakha nokuthengisa iye yandisa unyaka nonyaka. Imininingwane yomphakathi ikhombisa ukuthi ngo-2020, ukwehla kwanyanga zonke ngonyaka ekwakhiweni kwezindlu zokuhlala kabusha kwezentengiselwano bekunciphisiwe, futhi ukwehla konyaka okwenziwe ngonyaka kungu-1.87%. Ngo-2021, umkhuba wokutakula kulindeleke ukuthi uqhubeke. Kusukela ngoJanuwari kuya kuFebhuwari kulo nyaka, izinga lokukhula lendawo yokuthengisa yezindlu zezentengiselwano nasezakhiweni zokuhlala kabusha ziphinde zakha ama-104.9%, okungukunyuka okukhulu.
Ukushayela uwoyela:
Imakethe yezimboni yezimboni zokumba umthelela othotshiswa ikakhulukazi ngokuhlolwa kokuhlola kanye nokuthuthukisa intuthuko, enama-40% wephothifoliyo lokuhlola emhlabeni wonke elinikelwe ezinsizakalweni zobunjiniyela bokumba.
Ngesikhathi sokumba uwoyela, uketshezi lokumba kudlala indima ebalulekile ekuphatheni nasekukhuliseni ukusika, ukuqinisa imbobo ye-hole nokulinganisa ingcindezi yokwakheka, nokudlulisela ama-hydrodynamic. Ngakho-ke, emsebenzini wokushayela uwoyela, kubaluleke kakhulu ukugcina umswakama ofanele, i-viscosity, i-fluidity nezinye izinkomba zoketshezi lokumba. I-polyanionic cellulose, i-PAC, ingakhula, igcobe i-drill bit, bese idlulisa amandla e-hydrodynamic. Ngenxa yezimo eziyinkimbinkimbi zezwe endaweni yokugcina uwoyela kanye nobunzima bokushayela, kunesidingo esikhulu se-PAC.
Imboni yezesekeli yezemithi:
I-Nonionic Cellulose Afers isetshenziswa kabanzi emkhakheni wezemithi njenge-Exencients Executietical Excipients abanjengabakhulu, abahlakazekile, ama-emulsifiers kanye nabahluzi befilimu. Isetshenziselwa ukunamathela kwefilimu nokunamathela kwamathebulethi amakhambi, futhi futhi kungasetshenziselwa ukumiswa, amashebhu we-ophthalmic, amaphilisi antantayo, njll. Kusukela amathebulethi webanga lezemithi kunesidingo sokwenza ubumsulwa. kuyinkimbinkimbi futhi kunezinqubo eziningi zokuwasha. Uma kuqhathaniswa namanye amamaki emikhiqizo ye-cellulose ether, inani lokuqoqa liphansi futhi izindleko zokukhiqiza ziphakeme, kepha inani elingeziwe lomkhiqizo liphakeme. Ama-Execipieetients Emithi Exessients asetshenziswa ikakhulukazi emikhiqizweni efana namasheke amakhemikhali, imishanguzo yamalungelo amaShayina nemikhiqizo ye-biochemical.
Ngenxa yokuqalwa sekwedlule isikhathi kwemboni yezemithi yezwe yase-Execipietical Exessieticals, izinga lokuthuthuka elijwayelekile liphansi, futhi inqubo yezimboni idinga ukwenziwa ngcono. Kulululeki sokuphuma kwamalungiselelo amakhamikhali asekhaya, inani lokukhipha lezinto zokugqoka ezifuywayo asebeki ingxenye engezansi yengxenye ephansi ye-2% kuya ku-3%, okuphezulu kakhulu kune-15%. Kungabonakala ukuthi ama-Exessient asekhaya asekhaya asenethuba eliningi lokuthuthuka.
Ngokombono wokukhiqizwa kwe-Cellong Celsulase, i-Shandong Head inamandla amakhulu okukhiqiza, accounting for 12.5% wamandla okukhiqiza, alandelwa yi-Shandong Ruitai, e-Shandong Yiteng, ENyakatho TianPu, eNorth TianPu Chemical namanye amabhizinisi. Sekukonke, umncintiswano embonini uthuthukile, futhi ukugxila kulindeleke ukuthi kwandiswe.
