I-Furfural yimathiriyeli ekrwada yeutywala furfuryl, efunyenwe ngokuqhekeza kunye nokunciphisa i-polypentose equlethwe kwimveliso yezolimo kunye ne-sideline. I-Furfural ifakwe kwi-hydrogenatedutywala obunxilisayophantsi kwemeko ye-catalyst, kwaye yeyona nto iphambili ekrwada yemveliso ye-furfran resin.Utywala beFurfurylyimathiriyeli ekrwada yekhemikhali ebalulekileyo. Abasebenzisi abakhulu bavelisa i-furfural resin, i-furfuran resin, i-furfuryl alcohol - i-urea formaldehyde resin, i-phenolic resin, njl. Ikwasetyenziselwa ukulungisa i-asidi yeziqhamo, i-plasticizer, i-solvent kunye ne-rocket fuel. Ukongeza, ikwasetyenziswa kakhulu kumacandelo emizi-mveliso afana namafutha, iifayibha zokwenziwa, irabha, izibulali zinambuzane kunye nokuphosa. Kwangaxeshanye inokuvelisa i-plasticizer, ukumelana nokubanda kungcono kune-butyl alcohol kunye ne-octanol esters. Icalcium gluconate iyaveliswa. Ukuhlanganiswa kwedayi, i-pharmaceutical intermediates, ukuveliswa kweekhemikhali eziphakathi, ukuveliswa kwe-pyridine.
Inkcazo: Ulwelo olungenambala olubaleka lula, lujika lube mdaka okanye lubebomvu nzulu xa luvezwe lilanga nomoya. Inencasa ekrakra.
Ukunyibilika: kunokudityaniswa namanzi, kodwa ukungazinzi emanzini, ukunyibilika kwi-ethanol, ether, benzene kunye nekloroform, enganyibiliki kwi-petroleum hydrocarbons.
Iindlela zikaxakeka:
Unyango lokuvuza
Khupha abasebenzi kwindawo engcolisekileyo ubase kwindawo yokhuseleko, uthintele abasebenzi abangabalulekanga ukuba bangene kwindawo engcolisekileyo, kwaye unqumle umthombo womlilo. Abaphenduli bexesha likaxakeka bayacetyiswa ukuba banxibe izixhobo zokuphefumla ezizimeleyo kunye nempahla yokukhusela imichiza. Musa ukudibanisa ukuvuza ngokuthe ngqo, ukwenzela ukuba uqinisekise ukhuseleko lokuvuza. Tshiza amanzi ukunciphisa ukujika kwamanzi. Ixutywe nesanti okanye enye i-adsorbent engatshiyo yokufunxa. Emva koko iyaqokelelwa kwaye ithuthelwe kwindawo yokulahla inkunkuma ukuze ilahlwe. Iyakwazi nokuhlanjululwa ngamanzi amaninzi kwaye ixutywe kwinkqubo yamanzi amdaka. Okufana nesixa esikhulu sokuvuza, ukuqokelelwa kunye nokurisayikilisha okanye ukulahlwa okungenabungozi emva kwenkunkuma.
Indlela yokulahla inkunkuma: indlela yokutshisa, inkunkuma exutywe nesinyibilikisi esinokutsha emva kokutshiswa.
Amanyathelo okukhusela
Ukhuseleko lokuphefumla: Nxiba imaski yerhasi xa kunokwenzeka ukuba udibane nomphunga wayo. Nxiba ukuphefumla okuzimeleyo ngexesha lokuhlangula okanye ukubaleka.
Ukukhuselwa kwamehlo: Nxiba iiglasi zokhuseleko.
Impahla ekhuselayo: Nxiba iimpahla ezifanelekileyo zokuzikhusela.
Abanye: Ukutshaya, ukutya nokusela akuvumelekanga kwindawo. Emva kokusebenza, hlamba kakuhle. Gcina iimpahla ezinetyhefu ngokwahlukeneyo kwaye uzihlambe phambi kokuba uzisebenzise. Nikela ingqalelo kucoceko lobuqu.
Umlinganiselo woncedo lokuqala
Ukuthintana nolusu: Susa impahla engcolisekileyo kwaye ngoko nangoko uhlambe ngokucokisekileyo ngamanzi abalekayo.
Ukujongana kwamehlo: Yiphakamise ngoko nangoko inkophe uze uhlambe ngocoselelo ngamanzi abalekayo amaninzi.
Ukuphefumla: Susa ngokukhawuleza kwindawo yesiganeko uye kumoya omtsha. Gcina indlela yakho yomoya icocekile. Nika ioksijini xa ukuphefumla kunzima. Xa ukuphefumla kuyeka, mnike umoya ongengowamvelo ngoko nangoko. Funa unyango.
Ukungeniswa: Xa isigulana sivukile, sela amanzi amaninzi afudumeleyo ukuze ubangele ukuhlanza kwaye ufune unyango.
Indlela yokucima umlilo: amanzi anenkungu, ugwebu, umgubo owomileyo, ikharbon diokside, isanti.
Ukupakisha kunye nokugcinwa: Ukupakisha kwimigqomo yentsimbi, i-230kg, i-250kg ngomphanda. Gcina kwindawo epholileyo, eyomileyo kwaye engenamoya. Iifireworks azivumelekanga ngokungqongqo. Musa ukugcina kwaye uthuthe ngee-asidi ezinamandla, iikhemikhali ezinamandla ze-oxidizing kunye nokutya.
