1. Izinto ezilungileyo
(1) Inkxaso yomgaqo-nkqubo
Njengesixhobo esitsha esisekelwe kwibhayoloji kunye nesixhobo esiluhlaza nesinobuhlobo nokusingqongileyo, ukusetyenziswa ngokubanzi kwei-cellulose etherKwicandelo lemizi-mveliso kukho umkhwa wophuhliso wokwakha uluntu olunobuhlobo nokusingqongileyo nolonga izixhobo kwixesha elizayo. Uphuhliso lweli shishini luhambelana nenjongo enkulu yelizwe lam yokufezekisa uphuhliso loqoqosho oluzinzileyo. Urhulumente waseTshayina ukhuphe imigaqo-nkqubo kunye namanyathelo alandelayo afana “neSicwangciso seSizwe soPhuhliso lweSayensi neTekhnoloji seXesha eliPhakathi nelide (2006-2020)” kunye “neSicwangciso soPhuhliso lweShishini loLwakhiwo “seSicwangciso seShumi elinesibini seMinyaka emihlanu” ukuxhasa imboni ye-cellulose ether.
Ngokutsho kwengxelo ethi “2014-2019 China Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Investment Prospect Analysis Report” ekhutshwe yiChina Industry Information Network, eli lizwe likwaqulunqe imigangatho engqongqo yokukhusela okusingqongileyo, ephakamise ugxininiso kwimiba yokukhusela okusingqongileyo kwinqanaba elitsha. Isohlwayo esikhulu sokungcola okusingqongileyo sidlale indima entle ekusombululeni iingxaki ezinje ngokukhuphisana okungacwangciswanga kwishishini le-cellulose ether kunye nokudibanisa amandla okuvelisa amashishini.
(2) Ithuba lokufaka izicelo ezisezantsi libanzi kwaye imfuno iyanda
I-Cellulose ether yaziwa ngokuba yi-"industrial monosodium glutamate" kwaye ingasetyenziswa kwiindawo ezahlukeneyo zoqoqosho lwesizwe. Uphuhliso loqoqosho luya kuqhuba ngokungenakuphepheka ukukhula kweshishini le-cellulose ether. Ngophuhliso oluqhubekayo lwenkqubo yokufudukela kwabantu ezidolophini kwilizwe lam kunye notyalo-mali oluqinileyo lukarhulumente kwiimpahla ezizinzileyo kunye nezindlu ezifikelelekayo, ishishini lokwakha kunye nezixhobo zokwakha liya kwandisa kakhulu imfuno ye-cellulose ether. Kwimimandla yezonyango nokutya, ulwazi lwabantu ngempilo kunye nokukhuselwa kokusingqongileyo luya lukhula kancinci kancinci. Iimveliso ze-cellulose ether ezingenabungozi kwi-physiologically kwaye ezingangcolisiyo ezifana ne-HPMC ziya kuthatha indawo yezinye izinto ezikhoyo kancinci kancinci kwaye ziphuhlise ngokukhawuleza. Ukongeza, ukusetyenziswa kwe-cellulose ether kwiingubo, iiseramikhi, izinto zokuthambisa, isikhumba, iphepha, irabha, iikhemikhali zemihla ngemihla kunye nezinye izimboni kuya kusanda ngakumbi nangakumbi.
(3) Inkqubela phambili kwezobuchwepheshe iqhuba uphuhliso lweshishini
Kwinqanaba lokuqala lophuhliso lweshishini le-cellulose ether kwilizwe lam, i-ionic carboxymethyl cellulose ether (CMC) yayiyeyona mveliso iphambili. Ngokwenziwa kwe-ionic cellulose ether emelwe yi-PAC kunye ne-non-ionic cellulose ether emelwe yi-HPMC Ngophuhliso kunye nokuvuthwa kwenkqubo, intsimi yokusetyenziswa kwe-cellulose ether iye yandiswa. Ubuchwepheshe obutsha kunye neemveliso ezintsha ziya kuthatha indawo ngokukhawuleza yeemveliso ze-cellulose ether zemveli kwixesha elidlulileyo kwaye zikhuthaze uphuhliso lweshishini.
2. Izinto ezingathandekiyo
(1) Ukhuphiswano olungalungelelananga kwimarike
Xa kuthelekiswa nezinye iiprojekthi zeekhemikhali, ixesha lokwakhiwa kweprojekthi ye-cellulose ether lifutshane kwaye iimveliso zisetyenziswa kakhulu, ngoko ke kukho into yokwanda okungacwangciswanga kushishino. Ukongeza, ngenxa yokungabikho kwemigangatho yeshishini kunye nemigangatho yemarike eyenziwe lilizwe, kukho amashishini amancinci anezinga eliphantsi lobuchwephesha kunye notyalo-mali oluncinci kushishino; amanye awo aneengxaki zongcoliseko lokusingqongileyo ukuya kumanqanaba ahlukeneyo kwinkqubo yemveliso, kwaye asebenzisa umgangatho ophantsi. Ixabiso eliphantsi kunye nexabiso eliphantsi eliziswa lutyalo-mali oluphantsi lokukhusela okusingqongileyo luchaphazele imarike ye-cellulose ether, nto leyo ebangele imeko yokhuphiswano olungacwangciswanga kwimarike. Emva kokwaziswa kwetekhnoloji entsha kunye neemveliso ezintsha, indlela yokususa imarike iya kuphucula imeko ekhoyo yokhuphiswano olungacwangciswanga.
(2) Iimveliso zobugcisa obuphezulu kunye nexabiso elongezelelekileyo ziphantsi kolawulo lwangaphandle
Ishishini le-cellulose ether langaphandle laqala ngaphambili, kwaye amashishini emveliso amelwe yiDow Chemical kunye neHercules Group eMelika akwindawo ephambili ngokupheleleyo ngokwefomyula yemveliso kunye netekhnoloji. Zithintelwe yitekhnoloji, iinkampani ze-cellulose ether zasekhaya ikakhulu zivelisa iimveliso ezinexabiso eliphantsi ezineendlela ezilula zenkqubo kunye nobunyulu obuphantsi bemveliso, ngelixa iinkampani zangaphandle ziye zalawula imakethi yeemveliso ze-cellulose ether ezinexabiso eliphezulu ngokusebenzisa iingenelo zobuchwepheshe; ke ngoko, kwimakethi ye-cellulose ether yasekhaya, iimveliso eziphezulu kufuneka zingeniswe kwaye iimveliso ezikumgangatho ophantsi zineendlela ezibuthathaka zokuthumela ngaphandle. Nangona amandla emveliso yeshishini le-cellulose ether lasekhaya likhule ngokukhawuleza, ukukhuphisana kwalo kwimarike yamazwe ngamazwe kubuthathaka. Ngophuhliso lweshishini le-cellulose ether, imida yenzuzo yeemveliso ezinexabiso eliphantsi iya kuqhubeka incipha, kwaye amashishini asekhaya kufuneka afune impumelelo yetekhnoloji ukuze aphule ubukhosi bamashishini angaphandle kwimarike yemveliso ephezulu.
(3) Ukuguquguquka kwamaxabiso ezinto eziluhlaza
Umqhaphu ocociweyo, eyona nto iphambili ekrwadai-cellulose ether, yimveliso yezolimo. Ngenxa yotshintsho kwindalo esingqongileyo, imveliso kunye nexabiso ziya kutshintshatshintsha, nto leyo eya kuzisa ubunzima ekulungiseleleni izinto eziluhlaza kunye nolawulo lweendleko kumashishini asezantsi.
Ukongeza, iimveliso ze-petrochemical ezifana ne-propylene oxide kunye ne-methyl chloride nazo zizinto ezibalulekileyo zokuvelisa i-cellulose ether, kwaye amaxabiso azo achatshazelwa kakhulu kukuguquguquka kwimarike yeoyile ekrwada. Utshintsho kwimeko yezopolitiko yamazwe ngamazwe ludla ngokuba nefuthe kumaxabiso eoyile ekrwada, ngoko ke abavelisi be-cellulose ether kufuneka bajongane nemiphumo emibi yokuguquguquka rhoqo kwamaxabiso eoyile kwimveliso yabo kunye nokusebenza kwabo.
