Furfural ndi zopangira zamowa wa furfuryl, yomwe imapezeka mwa kusweka ndi kutaya madzi a polypentose omwe ali muzinthu zaulimi ndi zam'mbali. Furfural ndi hydrogenated kutimowa wonyezimirapansi pa chothandizira, ndipo ndiye chinthu chachikulu chopangira furfuran resin.Furfuryl mowandi zofunika organic mankhwala zopangira. Ogwiritsa ntchito kwambiri amapanga utomoni wa furfural, furfuran resin, furfuryl alcohol - urea formaldehyde resin, phenolic resin, etc. Amagwiritsidwanso ntchito pokonzekera zipatso za asidi, plasticizer, zosungunulira ndi rocket mafuta. Kuphatikiza apo, imagwiritsidwanso ntchito kwambiri m'mafakitale monga mafuta, ulusi wopangira, mphira, mankhwala ophera tizilombo ndi kuponyera. Nthawi yomweyo imatha kupanga plasticizer, kukana kuzizira kuli bwino kuposa mowa wa butyl ndi octanol esters. Calcium gluconate amapangidwa. Kuphatikizika kwa utoto, ma intermediates amankhwala, kupanga mankhwala apakati, kupanga pyridine.
Kufotokozera: Madzi opanda mtundu amayenda mosavuta, amasanduka bulauni kapena ofiira kwambiri akakhala padzuwa ndi mpweya. Ili ndi kukoma kowawa.
Kusungunuka: kumatha kusakanikirana ndi madzi, koma kosakhazikika m'madzi, kusungunuka mu Mowa, etha, benzene ndi chloroform, osasungunuka mu petroleum hydrocarbons.
Njira zadzidzidzi:
Chithandizo chotayikira
Chotsani ogwira ntchito pamalo owonongeka kupita kumalo otetezedwa, kuletsa ogwira ntchito osafunikira kulowa mdera lomwe lakhudzidwa, ndikudula kochokera moto. Othandizira zadzidzidzi amalangizidwa kuti azivala zida zopumira zokha komanso zovala zoteteza mankhwala. Osalumikizana ndi kutayikira mwachindunji, kuti mutsimikizire chitetezo cha kutayikira. Utsi madzi kuchepetsa nthunzi. Kusakaniza ndi mchenga kapena zina zosayaka adsorbent kuti mayamwidwe. Kenako amasonkhanitsidwa ndi kutumizidwa kumalo otaya zinyalala kuti akatayidwe. Ikhozanso kutsukidwa ndi madzi ochulukirapo ndikusungunuka m'madzi otayira. Monga kuchuluka kwa kutayikira, kusonkhanitsa ndi kubwezeretsanso kapena kutaya kopanda vuto pambuyo pa zinyalala.
Njira yotayira zinyalala: njira yowotchera, zinyalala zosakanizidwa ndi zosungunulira zoyaka moto zikapsa.
Njira zodzitetezera
Chitetezo chopumira: Valani chigoba cha mpweya ngati nkotheka kukhudza mpweya wake. Valani kupuma mokhazikika panthawi yopulumutsa mwadzidzidzi kapena pothawa.
Chitetezo m'maso: Valani magalasi oteteza maso.
Zovala zodzitetezera: Valani zovala zoyenera zodzitetezera.
Ena: Kusuta, kudya ndi kumwa ndi zoletsedwa pamalowa. Mukamaliza ntchito, sambani bwino. Sungani zovala zomwe zili ndi poizoni padera ndikuzichapa musanazigwiritse ntchito. Samalani ndi ukhondo waumwini.
Thandizo loyamba
Kukhudza Pakhungu: Chotsani zovala zomwe zili ndi kachilombo ndipo muzimutsuka nthawi yomweyo ndi madzi oyenda.
Kuyang'ana m'maso: Tukulani chikope nthawi yomweyo ndikutsuka bwino ndi madzi othamanga.
Kukoka mpweya: Chotsani mwachangu pamalopo kupita ku mpweya wabwino. Njira yanu yopita ndi mpweya ikhale yoyera. Perekani mpweya pamene kupuma kuli kovuta. Mpweya ukasiya, perekani mpweya wochita kupanga nthawi yomweyo. Pitani kuchipatala.
Kumeza: Wodwala akadzuka, imwani madzi ambiri ofunda kuti musanze ndi kupita kuchipatala.
Njira yozimitsira moto: madzi ankhuku, thovu, ufa wouma, mpweya woipa, mchenga.
Kulongedza ndi kusunga: Kulongedza mu ng'oma zachitsulo, 230kg, 250kg pa mbiya. Sungani pamalo ozizira, owuma komanso mpweya wabwino. Zozimitsa moto ndizoletsedwa. Osasunga ndi kunyamula ndi zidulo amphamvu, mankhwala amphamvu oxidizing ndi zakudya.
