I-cellulose ether uhlobo lwezinto zemvelo ezithathwe ku-polymer, ezinezici ze-emulsification kanye ne-suspension. Phakathi kwezinhlobo eziningi, i-HPMC iyona enomkhiqizo ophezulu kakhulu futhi esetshenziswa kakhulu, futhi umkhiqizo wayo uyanda ngokushesha.
Eminyakeni yamuva nje, ngenxa yokukhula komnotho wezwe, ukukhiqizwa kwe-cellulose ether ezweni lakithi kuye kwanda unyaka nonyaka. Ngesikhathi esifanayo, ngentuthuko yesayensi nobuchwepheshe basekhaya, ama-cellulose ether aphezulu ayedinga inani elikhulu lokungeniswa kwamanye amazwe manje asetholakala kancane kancane, futhi inani lokuthunyelwa kwamanye amazwe lama-cellulose ether asekhaya liyaqhubeka nokukhula. Idatha ibonisa ukuthi kusukela ngoJanuwari kuya kuNovemba 2020, ukuthunyelwa kwamanye amazwe kwe-cellulose ether eShayina kufinyelele kumathani angu-64,806, ukwanda konyaka nonyaka okungu-14.2%, okuphakeme kunomthamo wokuthunyelwa kwamanye amazwe kulo lonke u-2019.
I-cellulose ether ithintwa yintengo kakotini ephezulu：
Izinto eziyinhloko zokusetshenziswa ze-cellulose ether zifaka phakathi imikhiqizo yezolimo neyamahlathi okuhlanganisa ukotini ocwengisisiwe kanye nemikhiqizo yamakhemikhali okuhlanganisa ne-propylene oxide. Izinto zokusetshenziswa zekotoni ocwengisisiwe yizinhlayiya zikakotini. Izwe lami linomkhiqizo omningi kakotini, futhi izindawo zokukhiqiza izinhlayiya zikakotini zigxile kakhulu eShandong, Xinjiang, Hebei, Jiangsu nakwezinye izindawo. Izinhlayiya zikakotini ziningi kakhulu futhi zitholakala ngobuningi.
Ukotini uthatha ingxenye enkulu kakhulu esakhiweni sezomnotho wezolimo, futhi intengo yawo ithintwa izici eziningi ezifana nezimo zemvelo kanye nokuhlinzekwa kanye nesidingo samazwe ngamazwe. Ngokufanayo, imikhiqizo yamakhemikhali efana ne-propylene oxide kanye ne-methyl chloride nayo ithintwa yintengo kawoyela ongahluziwe wamazwe ngamazwe. Njengoba izinto zokusetshenziswa ziyingxenye enkulu esakhiweni sezindleko ze-cellulose ether, ukuguquguquka kwamanani entengo yezinto zokusetshenziswa kuthinta ngqo intengo yokuthengisa ye-cellulose ether.
Ngenxa yokucindezeleka kwezindleko, abakhiqizi be-cellulose ether bavame ukudlulisela ingcindezi ezimbonini ezingezansi, kodwa umphumela wokudlulisela uthintwa ubunzima bemikhiqizo yobuchwepheshe, ukuhlukahluka komkhiqizo kanye nenani elengeziwe lezindleko zomkhiqizo. Ngokuvamile, amabhizinisi anezithiyo zobuchwepheshe eziphezulu, izigaba zomkhiqizo ocebile, kanye nenani elengeziwe eliphezulu anezinzuzo ezinkulu, futhi amabhizinisi azogcina izinga elizinzile lenzuzo enkulu; ngaphandle kwalokho, amabhizinisi kudingeka abhekane nengcindezi enkulu yezindleko. Ngaphezu kwalokho, uma indawo yangaphandle ingazinzile futhi ububanzi bokushintshashintsha komkhiqizo bukhulu, izinkampani zezinto zokusetshenziswa ezingenhla zizimisele kakhulu ukukhetha amakhasimende angezansi anesilinganiso esikhulu sokukhiqiza kanye namandla aqinile aphelele ukuqinisekisa izinzuzo zezomnotho ezifika ngesikhathi nokunciphisa izingozi. Ngakho-ke, lokhu kunciphisa intuthuko yamabhizinisi amancane e-cellulose ether ngezinga elithile.
Isakhiwo Semakethe Esingezansi：
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imakethe yesidingo esingezansi izokhula ngokufanele. Ngesikhathi esifanayo, ububanzi bezicelo ezingezansi kulindeleke ukuthi buqhubeke nokukhula, futhi isidingo esingezansi sizogcina ukukhula okuzinzile. Esakhiweni semakethe esingezansi se-cellulose ether, izinto zokwakha, ukuhlola uwoyela, ukudla kanye neminye imikhakha kuthathe indawo enkulu. Phakathi kwazo, umkhakha wezinto zokwakha uyimakethe enkulu yabathengi, ebiza ngaphezu kwama-30%.
Imboni yokwakha iyinsimu enkulu kunazo zonke yabathengi yemikhiqizo ye-HPMC：
Embonini yokwakha, imikhiqizo ye-HPMC idlala indima ebalulekile ekubopheni nasekugcinweni kwamanzi. Ngemva kokuxuba inani elincane le-HPMC nodaka lukasimende, kungandisa i-viscosity, amandla okuthamba nokusika kodaka lukasimende, udaka, i-binder, njll., ngaleyo ndlela kuthuthukiswe ukusebenza kwezinto zokwakha, kuthuthukiswe ikhwalithi yokwakha kanye nokusebenza kahle kokwakhiwa kwemishini. Ngaphezu kwalokho, i-HPMC nayo iyi-retarder ebalulekile ekukhiqizweni nasekuthuthweni kodaka lwezentengiselwano, olungavimba amanzi futhi luthuthukise i-rheology yodaka lukasimende. Njengamanje, i-HPMC ingumkhiqizo oyinhloko we-cellulose ether osetshenziswa ezintweni zokuvala zokwakha.
Imboni yokwakha iyimboni eyinhloko yomnotho wezwe lami. Idatha ikhombisa ukuthi indawo yokwakha izindlu inyukile isuka kumamitha-skwele ayizigidigidi eziyi-7.08 ngo-2010 yaya kumamitha-skwele ayizigidigidi eziyi-14.42 ngo-2019, okukhuthaze kakhulu ukukhula kwemakethe ye-cellulose ether.
Ukuchuma okuphelele kwemboni yezindlu kukhuphuke kabusha, kanti indawo yokwakha kanye neyokuthengisa ikhuphuke unyaka nonyaka. Idatha yomphakathi ikhombisa ukuthi ngo-2020, ukwehla kwanyanga zonke konyaka endaweni entsha yokwakha yezindlu zokuhlala zezentengiselwano kuye kuncipha, kanti ukwehla konyaka nonyaka kube ngu-1.87%. Ngo-2021, umkhuba wokululama kulindeleke ukuthi uqhubeke. Kusukela ngoJanuwari kuya kuFebhuwari kulo nyaka, izinga lokukhula kwendawo yokuthengisa yezindlu zezentengiselwano kanye nezakhiwo zokuhlala likhuphuke laya ku-104.9%, okuwukukhula okukhulu.
Ukubhoboza uwoyela:
Imakethe yezinsizakalo zobunjiniyela bokubhola ithinteka kakhulu ekutshalweni kwezimali kokuhlola nokuthuthukiswa komhlaba wonke, cishe u-40% wephothifoliyo yokuhlola yomhlaba wonke izinikele ezinsizakalweni zobunjiniyela bokubhola.
Ngesikhathi sokubhoboza uwoyela, uketshezi lokubhoboza ludlala indima ebalulekile ekuthwaleni nasekulengiseni izicucu, ukuqinisa izindonga zemigodi nokulinganisela ingcindezi yokwakheka, ukupholisa nokugcoba izingcezu zokubhoboza, nokudlulisa amandla e-hydrodynamic. Ngakho-ke, emsebenzini wokubhoboza uwoyela, kubaluleke kakhulu ukugcina umswakama ofanele, i-viscosity, ukugeleza kanye nezinye izinkomba zoketshezi lokubhoboza. I-polyanionic cellulose, i-PAC, ingajiya, igcobe i-drill bit, futhi idlulise amandla e-hydrodynamic. Ngenxa yezimo eziyinkimbinkimbi ze-geological endaweni yokugcina uwoyela kanye nobunzima bokubhoboza, kunesidingo esikhulu se-PAC.
Imboni yezesekeli zemithi:
Ama-ether e-cellulose angewona ama-ionic asetshenziswa kabanzi embonini yezemithi njengezinto ezisizayo zezemithi ezifana nezithina, izihlakaza, ama-emulsifier kanye nama-film formers. Isetshenziselwa ukumboza ifilimu kanye nokunamathela kwamaphilisi ezemithi, futhi ingasetshenziswa nasekumisweni, ekulungiseleleni amehlo, kumaphilisi antantayo, njll. Njengoba i-ether ye-cellulose yezinga lezemithi inezidingo eziqinile ngobumsulwa kanye nokuthamba komkhiqizo, inqubo yokukhiqiza iyinkimbinkimbi kakhulu futhi kunezinqubo eziningi zokuwasha. Uma kuqhathaniswa namanye amazinga emikhiqizo ye-ether ye-cellulose, izinga lokuqoqwa liphansi futhi izindleko zokukhiqiza ziphakeme, kodwa inani elengeziwe lomkhiqizo nalo liphakeme. Izinto ezisizayo zezemithi zisetshenziswa kakhulu emikhiqizweni yokulungiselela efana nokulungiselela amakhemikhali, imithi ye-patent yaseShayina kanye nemikhiqizo ye-biochemical.
Ngenxa yokuqala sekwephuzile kwemboni yezithako zemithi ezweni lami, izinga lokuthuthukiswa kwamanje liphansi, futhi indlela yokusebenza kwemboni idinga ukuthuthukiswa kakhulu. Enani lokukhishwa kwemithi yasekhaya, inani lokukhishwa kwezithako zemithi yasekhaya libalelwa engxenyeni ephansi kakhulu engu-2% kuya ku-3%, ephansi kakhulu kunengxenye yezithako zemithi zakwamanye amazwe, engaba ngu-15%. Kungabonakala ukuthi izithako zemithi yasekhaya zisenendawo enkulu yokuthuthukiswa. Kulindeleke ukuthi kukhuthaze ngempumelelo ukukhula kwemakethe ye-cellulose ether ehlobene.
Ngokombono wokukhiqizwa kwe-cellulose ether yasekhaya, iShandong Head inomthamo omkhulu wokukhiqiza, ohlanganisa u-12.5% wamandla okukhiqiza aphelele, kulandelwe yiShandong RUITAI, Shandong YITENG, North TIANPU Chemical kanye namanye amabhizinisi. Sekukonke, ukuncintisana embonini kukhulu, futhi ukuhlushwa kulindeleke ukuthi kwande kakhulu.
