    Daim ntawv thov

    【Siv Ib】
    Siv los ua raw khoom rau synthesis ntawm ntau yam furan resins, anti-corrosion txheej, thiab kuj yog ib qho hnyav hnyav.
    【Siv Ob】
    Nws yog ib qho hnyav hnyav thiab foob pob hluav taws roj rau resins, varnishes thiab pigments. Nws tseem tuaj yeem siv rau hauv cov khoom siv hluavtaws, roj hmab, tshuaj tua kab thiab kev lag luam foundry.
    【Siv peb】
    GB 2761-1997 qhia tias nws raug tso cai siv cov txuj lom zaub mov. Feem ntau yog siv los npaj coke-flavored flavors.

    【Siv plaub】
    Furfuryl cawv yog siv nyob rau hauv cov organic synthesis, thiab levulinic acid (txiv hmab txiv ntoo acid) yog tau los ntawm hydrolysis, uas yog ib tug nruab nrab ntawm kev noj haus tshuaj calcium fructate. Furan resins nrog ntau yam khoom (xws li furfuryl cawv resins, furan I lossis furan II resins), furfuryl cawv-urea-formaldehyde resins thiab phenolic resins tuaj yeem npaj los ntawm furfuryl cawv;

    【Siv tsib】
    Solvent. Organic synthesis (tsim anthracene, resin, thiab lwm yam). khaws cia. txuj lom.

    cov nqe lus them nqi

    Cia

    Nws yuav tsum tau muab kaw thiab tiv thaiv los ntawm lub teeb thiab khaws cia rau hauv qhov chaw txias.

    Tsis txhob ze rau cov kua qaub uas muaj zog thaum khaws cia.

    Khaws kom deb ntawm qhov dej, thiab tuaj yeem khaws cia rau hauv cov hlau, me me hlau lossis txhuas ntim.

    Kev ruaj ntseg

    1. Tsis txhob sib cuag nrog huab cua. Tsis txhob sib cuag nrog cov kua qaub chlorides, oxygen, thiab cov kua qaub.
    2. Cov kua dej tsis muaj xim thiab yooj yim ntws, nws yuav tig xim av lossis xim liab thaum raug tshav ntuj lossis huab cua. Muaj iab saj. Nws yog miscible nrog dej, tab sis tsis ruaj khov hauv dej, yooj yim soluble hauv ethanol, ether, benzene thiab chloroform, thiab insoluble hauv roj av hydrocarbons. Insoluble hauv alkanes.

    3. Cov khoom siv tshuaj: Furfuryl cawv tuaj yeem txo cov tshuaj nitrate ammonia thaum rhuab. Nws yog ruaj khov rau alkali, tab sis nws yog ib qho yooj yim rau resinize nyob rau hauv qhov kev txiav txim ntawm acid los yog oxygen nyob rau hauv cov huab cua. Tshwj xeeb, nws yog qhov tsis tshua muaj siab rau cov kua qaub uas muaj zog thiab feem ntau ntes hluav taws thaum cov tshuaj tiv thaiv khaus. Nws tshwm xiav thaum rhuab nrog ib tug sib tov ntawm diphenylamine, acetic acid, thiab concentrated sulfuric acid (diphenylamine cov tshuaj tiv thaiv).

    4. Muaj nyob rau hauv cov pa luam yeeb-kho cov nplooj, burley luam yeeb nplooj, oriental nplooj luam yeeb thiab pa luam yeeb.
