I-Cellulose ether luhlobo lwezinto zendalo ezithathwe kwi-polymer, ezineempawu ze-emulsification kunye ne-suspension. Phakathi kweentlobo ezininzi, i-HPMC yeyona inemveliso ephezulu kwaye isetyenziswa kakhulu, kwaye imveliso yayo iyanda ngokukhawuleza.
Kwiminyaka yakutshanje, ngenxa yokukhula koqoqosho lwesizwe, imveliso ye-cellulose ether kwilizwe lam inyukile minyaka le. Kwangaxeshanye, ngophuhliso lwesayensi netekhnoloji yasekhaya, ii-cellulose ethers eziphezulu ezazifuna inani elikhulu lokungeniswa kwamanye amazwe ngoku zithunyelwa ngokuthe ngcembe, kwaye umthamo wokuthunyelwa kwamanye amazwe wee-cellulose ethers zasekhaya uyaqhubeka nokwanda. Idatha ibonisa ukuba ukususela ngoJanuwari ukuya kuNovemba ka-2020, ukuthunyelwa kwamanye amazwe kwe-cellulose ether eTshayina kufikelele kwiitoni ezingama-64,806, ukunyuka konyaka nge-14.2%, okungaphezulu kunomthamo wokuthunyelwa kwamanye amazwe kulo lonke u-2019.
I-Cellulose ether ichatshazelwa ngamaxabiso aphezulu omqhaphu：
Izinto eziphambili ezisetyenziswa kwi-cellulose ether ziquka iimveliso zolimo nezamahlathi kuquka umqhaphu ocociweyo kunye neemveliso zeekhemikhali kuquka i-propylene oxide. Izinto ezisetyenziswa kwi-cotton ecociweyo zii-cotton linters. Ilizwe lam linemveliso eninzi yomqhaphu, kwaye iindawo zemveliso yee-cotton linters zigxile kakhulu eShandong, Xinjiang, Hebei, Jiangsu nakwezinye iindawo. Ii-cotton linters zininzi kakhulu kwaye zifumaneka kakhulu.
Umqhaphu uthatha inxalenye enkulu kwisakhiwo sezoqoqosho lwezolimo, kwaye ixabiso lawo lichaphazeleka ziinkalo ezininzi ezifana neemeko zendalo kunye nokunikezelwa kunye nemfuno yamazwe ngamazwe. Ngokufanayo, iimveliso zeekhemikhali ezifana nepropylene oxide kunye ne-methyl chloride nazo zichaphazeleka ngamaxabiso eoyile ekrwada yamazwe ngamazwe. Ekubeni izinto ezikrwada zibangela inxalenye enkulu kwisakhiwo seendleko ze-cellulose ether, ukuguquguquka kwamaxabiso ezinto ezikrwada kuchaphazela ngokuthe ngqo ixabiso lokuthengisa le-cellulose ether.
Ukuphendula uxinzelelo lweendleko, abavelisi be-cellulose ether badla ngokudlulisela uxinzelelo kumashishini asezantsi, kodwa isiphumo sokudluliselwa sichaphazeleka bubunzima beemveliso zobugcisa, ukwahluka kwemveliso kunye nexabiso elongeziweyo leendleko zemveliso. Ngokwesiqhelo, amashishini anemiqobo ephezulu yobugcisa, iindidi zemveliso ezityebileyo, kunye nexabiso elongeziweyo eliphezulu aneenzuzo ezinkulu, kwaye amashishini aya kugcina inqanaba elizinzileyo lenzuzo epheleleyo; kungenjalo, amashishini kufuneka ajongane noxinzelelo olukhulu lweendleko. Ukongeza, ukuba imeko yangaphandle ayizinzanga kwaye uluhlu lokuguquguquka kwemveliso lukhulu, iinkampani zezinto ezikrwada eziphezulu zizimisele ngakumbi ukukhetha abathengi abasezantsi abanemveliso enkulu kunye namandla aqinileyo apheleleyo ukuqinisekisa iingenelo zoqoqosho ngexesha elifanelekileyo kunye nokunciphisa iingozi. Ke ngoko, oku kunciphisa uphuhliso lwamashishini amancinci e-cellulose ether ukuya kwinqanaba elithile.
Ulwakhiwo lweMarike olusezantsi：
Ngokuqhubeka kwenzululwazi netekhnoloji, imakethi yemfuno esezantsi iya kukhula ngokufanelekileyo. Kwangaxeshanye, kulindeleke ukuba uluhlu lwezicelo ezisezantsi luqhubeke nokukhula, kwaye imfuno esezantsi iya kugcina ukukhula okuzinzileyo. Kwisakhiwo semakethi esisezantsi se-cellulose ether, izixhobo zokwakha, uphando lweoyile, ukutya kunye nezinye iindawo zithatha indawo enkulu. Phakathi kwazo, icandelo lezixhobo zokwakha lelona marike inkulu yabathengi, libalelwa ngaphezulu kwe-30%.
Ishishini lokwakha lelona candelo likhulu labathengi beemveliso ze-HPMC：
Kwishishini lokwakha, iimveliso ze-HPMC zidlala indima ebalulekileyo ekubopheni nasekugcineni amanzi. Emva kokuxuba inani elincinci le-HPMC nodaka lwesamente, kunokunyusa i-viscosity, amandla okutsalwa kunye nokuchetywa kodaka lwesamente, udaka, i-binder, njl.njl., ngaloo ndlela kuphuculwe ukusebenza kwezixhobo zokwakha, kuphuculwe umgangatho wokwakha kunye nokusebenza kakuhle kolwakhiwo loomatshini. Ukongeza, i-HPMC ikwayinto ebalulekileyo ekubuyiseleni nasekuthuthweni kwekhonkrithi yorhwebo, enokuvala amanzi kwaye iphucule i-rheology yekhonkrithi. Okwangoku, i-HPMC yeyona mveliso iphambili ye-cellulose ether esetyenziswa kwizixhobo zokuvala izakhiwo.
Ishishini lokwakha lishishini eliphambili kuqoqosho lwelizwe lam. Idatha ibonisa ukuba indawo yokwakha izindlu inyukile ukusuka kwi-7.08 yeebhiliyoni zeemitha zesikwere ngo-2010 ukuya kwi-14.42 yeebhiliyoni zeemitha zesikwere ngo-2019, nto leyo eye yakhuthaza kakhulu ukukhula kwemarike ye-cellulose ether.
Impumelelo iyonke yeshishini lezindlu ibuyele esiqhelweni, kwaye indawo yokwakha neyokuthengisa inyukile unyaka nonyaka. Idatha kawonke-wonke ibonisa ukuba ngo-2020, ukwehla kwenyanga nonyaka kwindawo entsha yokwakha izindlu zokuhlala zorhwebo kuye kwancipha, kwaye ukwehla konyaka nonyaka kube yi-1.87%. Ngo-2021, kulindeleke ukuba imeko yokubuyela kwimeko yesiqhelo iqhubeke. Ukususela ngoJanuwari ukuya kuFebruwari kulo nyaka, izinga lokukhula kwendawo yokuthengisa izindlu zorhwebo nezakhiwo zokuhlala libuyele esiqhelweni ukuya kwi-104.9%, nto leyo ebangela ukwanda okukhulu.
Ukubhola ioyile:
Imarike yoshishino lweenkonzo zobunjineli bokubhola ichaphazeleka ngakumbi lutyalo-mali lokuhlola nophuhliso lwehlabathi, malunga ne-40% yepotifoliyo yokuhlola yehlabathi izinikele kwiinkonzo zobunjineli bokubhola.
Ngexesha lokugrumba ioyile, ulwelo lokugrumba ludlala indima ebalulekileyo ekuthwaleni nasekumiseni iziqwenga, ukuqinisa iindonga zemingxuma kunye nokulinganisela uxinzelelo lokwakheka, ukupholisa kunye nokuthambisa iibhithi zokugrumba, kunye nokudlulisa amandla e-hydrodynamic. Ke ngoko, kumsebenzi wokugrumba ioyile, kubaluleke kakhulu ukugcina umswakama ofanelekileyo, i-viscosity, i-fluidity kunye nezinye izalathisi zolwelo lokugrumba. I-polyanionic cellulose, i-PAC, inokuthi ityebe, ithambise i-drill bit, kwaye idlulise amandla e-hydrodynamic. Ngenxa yeemeko ezinzima zejoloji kwindawo yokugcina ioyile kunye nobunzima bokugrumba, kukho imfuno enkulu ye-PAC.
Imboni yezixhobo zamayeza:
Ii-ether ze-cellulose ezingezizo i-ionic zisetyenziswa kakhulu kwishishini lezemithi njengezinto ezincedisayo kumayeza ezifana nezithina, izisasazi, ii-emulsifiers kunye nee-film formers. Isetyenziselwa ukugquma ifilimu kunye nokuncamathisela iipilisi zezemithi, kwaye ingasetyenziselwa ukuxutywa, amalungiselelo okujonga amehlo, iipilisi ezidadayo, njl. Ekubeni i-ether ye-cellulose yeklasi yezemithi ineemfuno ezingqongqo kubunyulu kunye nokuxinana kwemveliso, inkqubo yokuvelisa iyinkimbinkimbi kwaye kukho iinkqubo ezininzi zokuhlamba. Xa kuthelekiswa nezinye iintlobo zeemveliso ze-ether ze-cellulose, izinga lokuqokelelwa liphantsi kwaye iindleko zemveliso ziphezulu, kodwa ixabiso elongezelelweyo lemveliso nalo liphezulu. Izinto ezincedayo kumayeza zisetyenziswa kakhulu kwiimveliso zokulungiselela ezifana nokulungiselela iikhemikhali, amayeza e-patent aseTshayina kunye neemveliso ze-biochemical.
Ngenxa yokuqala kade kweshishini lezinto ezinceda amayeza kwilizwe lam, inqanaba lophuhliso lilonke langoku liphantsi, kwaye indlela yokusebenza kweshishini kufuneka iphuculwe ngakumbi. Kwixabiso lemveliso yezinto ezisetyenziselwa amayeza asekhaya, ixabiso lemveliso yezinto ezincedisa amayeza asekhaya libalelwa kwi-2% ukuya kwi-3%, eliphantsi kakhulu kunenani lezinto ezinceda amayeza angaphandle, elimalunga ne-15%. Kuyabonakala ukuba izinto ezinceda amayeza asekhaya zisenendawo enkulu yokuphuhliswa. Kulindeleke ukuba kukhuthaze ngempumelelo ukukhula kwemarike ye-cellulose ether enxulumene nayo.
Ngokwembono yemveliso ye-cellulose ether yasekhaya, iShandong Head inomthamo omkhulu wemveliso, ithatha i-12.5% yamandla emveliso iyonke, ilandelwa yiShandong RUITAI, iShandong YITENG, iNorth TIANPU Chemical kunye namanye amashishini. Lilonke, ukhuphiswano kushishino lunamandla kakhulu, kwaye kulindeleke ukuba uxinzelelo lunyuke ngakumbi.
