Furfural yog cov khoom siv raw ntawmfurfuyl cawv, uas yog tau los ntawm kev tawg thiab dehydrating polypentose muaj nyob rau hauv cov khoom ua liaj ua teb thiab sab nraum zoov. Furfural yog hydrogenated raufurfural cawvnyob rau hauv cov xwm txheej ntawm catalyst, thiab yog lub ntsiab raw khoom rau furfuran resin ntau lawm.Furfuryl cawvyog ib qho tseem ceeb organic chemical raw khoom. Cov neeg siv tseem ceeb tsim cov khoom siv furfural, furfuran resin, furfuryl cawv - urea formaldehyde resin, phenolic resin, thiab lwm yam. Nws kuj yog siv los npaj cov txiv hmab txiv ntoo acid, plasticizer, hnyav thiab foob pob hluav taws roj. Tsis tas li ntawd, nws kuj tau siv dav hauv kev lag luam xws li roj, hluavtaws fibers, roj hmab, tshuaj tua kab thiab casting. Nyob rau tib lub sijhawm tuaj yeem tsim cov yas yas, kev tiv thaiv txias yog zoo dua li butyl cawv thiab octanol esters. Calcium gluconate yog tsim. Synthesis ntawm dyes, kws tshuaj intermediates, tsim tshuaj intermediates, zus tau tej cov pyridine.
Nqe lus piav qhia: Cov kua dej tsis muaj xim yooj yim ntws, tig xim av lossis liab liab thaum raug tshav ntuj thiab huab cua. Nws muaj ib tug iab saj.
Solubility: tuaj yeem sib xyaw nrog dej, tab sis tsis ruaj khov hauv dej, soluble hauv ethanol, ether, benzene thiab chloroform, insoluble hauv roj av hydrocarbons.
Txoj kev xwm txheej ceev:
Kev kho cov dej ntws tawm
Tshem tawm cov neeg ua haujlwm tawm ntawm thaj chaw muaj kab mob mus rau thaj chaw nyab xeeb, txwv tsis pub cov neeg ua haujlwm tsis cuam tshuam nkag mus rau thaj chaw muaj kab mob, thiab txiav tawm qhov hluav taws kub. Cov neeg muaj xwm txheej ceev tau qhia kom hnav cov cuab yeej ua pa ntawm tus kheej thiab cov khaub ncaws tiv thaiv tshuaj. Tsis txhob tiv tauj cov xau ncaj qha, txhawm rau ua kom muaj kev nyab xeeb ntawm cov xau. Txau dej kom txo cov evaporation. Sib tov nrog xuab zeb los yog lwm yam tsis-combustible adsorbent rau nqus. Tom qab ntawd nws tau sau thiab thauj mus rau qhov chaw pov tseg pov tseg. Nws tseem tuaj yeem yaug nrog dej ntau thiab diluted rau hauv cov dej khib nyiab. Xws li ib tug loj npaum li cas ntawm to, sau thiab recycling los yog harmless pov tseg tom qab pov tseg.
Txoj kev pov tseg pov tseg: txoj kev incineration, khib nyiab tov nrog cov kuab tshuaj flammable tom qab incineration.
Kev tiv thaiv
Kev tiv thaiv ua pa: Hnav lub npog ntsej muag roj thaum muaj peev xwm tiv taus nws cov pa. Hnav nws tus kheej ua pa thaum muaj xwm txheej ceev los yog khiav tawm.
Kev tiv thaiv qhov muag: Hnav tsom iav kev nyab xeeb.
Cov khaub ncaws tiv thaiv: Hnav khaub ncaws tiv thaiv tsim nyog.
Lwm tus: Kev haus luam yeeb, noj mov thiab haus cawv yog txwv tsis pub nyob ntawm qhov chaw. Tom qab ua haujlwm, ntxuav kom huv si. Khaws cov khaub ncaws uas muaj tshuaj lom sib cais thiab ntxuav lawv ua ntej siv. Ua tib zoo saib xyuas tus kheej.
Kev ntsuas thawj zaug
Kev sib cuag ntawm daim tawv nqaij: Tshem cov khaub ncaws uas tsis huv thiab yaug tam sim ntawd nrog dej ntws.
Kev sib cuag qhov muag: Tam sim ntawd rub daim tawv muag thiab yaug kom huv si nrog dej txaus.
Inhalation: Tshem tawm sai sai ntawm qhov chaw mus rau huab cua ntshiab. Khaws koj txoj hlab cua kom meej. Muab cov pa oxygen thaum ua pa nyuaj. Thaum ua pa nres, muab kev ua pa tawm sai sai. Nrhiav kev kho mob.
Kev Noj Qab Haus Huv: Thaum tus neeg mob tsaug zog, haus dej sov kom ntau kom ntuav thiab nrhiav kev kho mob.
Txoj kev tua hluav taws: dej pos huab, ua npuas ncauj, hmoov qhuav, carbon dioxide, xuab zeb.
Ntim thiab khaws cia: Ntim hauv cov nruas hlau, 230kg, 250kg ib chim. Khaws rau hauv qhov chaw txias, qhuav thiab zoo-ventilated. Cov foob pob hluav taws raug txwv nruj heev. Tsis txhob khaws thiab thauj nrog cov kua qaub uas muaj zog, muaj zog oxidizing tshuaj thiab khoom noj khoom haus.
