I-Phenol Formaldehyde Resin CAS 9003-35-4 Ikhwalithi Ephezulu Nentengo Ephansi Isithombe Esifakiwe
  • I-Phenol Formaldehyde Resin CAS 9003-35-4 Ikhwalithi Ephezulu Nentengo Ephansi

Incazelo emfushane:


  • Intengo ye-FOB eyinkomba:
    Kuyaxoxiswa
    / Ithani
  • Imbobo:China
  • Imigomo Yokukhokha:L/C, T/T, Western Union
  • I-CAS:9003-35-4

    • Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Igama Lomkhiqizo:i-phenolic resin

    Ifomethi ye-molecular:

    Inombolo ye-CAS:9003-35-4

    Isakhiwo samangqamuzana omkhiqizo:

    i-phenolic resin

    IZIMPAHLA ZAMAKHEMIkhali

    I-phenol-formaldehyde resin ilungiswa ngale ndlela elandelayo:
    C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
    Ama-Resins esiteji esisodwa.Isilinganiso se-formaldehyde ne-phenol siphezulu ngokwanele ukuvumela inqubo ye-thermosetting ukuba yenzeke ngaphandle kokwengezwa kweminye imithombo yezixhumanisi eziphambanayo.
    Ama-Resins anezigaba ezimbili.Isilinganiso se-formaldehyde ne-phenol siphansi ngokwanele ukuvimbela ukusabela kwe-thermosetting ukuthi kwenzeke ngesikhathi sokwenziwa kwe-resin.Kuleli qophelo i-resin ibizwa ngokuthi i-novolac resin.Kamuva, i-hexamethylenetetramine ifakwa kokusebenza ukuze isebenze njengomthombo wamakhemikhali ahlanganayo ngesikhathi sokusebenza kokubumba (kanye nokuguqulelwa ku-thermoset noma isimo esilashiwe).

    INDAWO YOKUSEBENZA

    Ezemithi
    Imboni Yamafutha
    Isibulala-zinambuzane
    Injini ye-Diesel Fuel
    Isiqandisi
    I-Aerosol Spray

    Ama-phenolic resins asetshenziselwa izingxenye ezishibhile ezidinga izakhiwo ezinhle zokuvikela ugesi, ukumelana nokushisa, noma ukumelana namakhemikhali.Isilinganiso sempilo yeshelufu yale resin cishe inyanga engu-1 ku-21.1°C.Lokhu kunganwetshwa ngokuyigcina esiqandisini ku-1.6 kuya ku-10°C.Ukushintsha i-catalyst (ngokuhambisana nobukhulu be-cast) nokukhuphula izinga lokushisa lokwelapha libe ngu-93°C kuzoshintsha isikhathi sokwelapha sisuke kumahora angu-8 siye sibe sifushane njengemizuzu engu-15.
    Okunye ukuncipha kwenzeka ekubunjweni okuqediwe (0.012 kuya ku-0.6 mm/mm), kuye ngenani lokugcwalisa, inani le-catalyst, kanye nezinga lokwelapha.Imijikelezo yokwelapha esheshayo ikhiqiza izinga eliphezulu lokuncipha.Njengoba umjikelezo wokwelapha ungasheshisa, ama-phenolic asetshenziswa ekusebenzeni okufushane.
    Izingxenye ze-cast phenolic zisuswa kalula esikhunjeni uma kusetshenziswa ama-ejenti ahlukanisayo anconywe umphakeli.I-Posteuring ithuthukisa izakhiwo eziyisisekelo zokubunjwa okuqediwe.

    UTHENGA KANJANI KITHI

    I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi: 

    1. Ezokuphepha

    Ukuphepha kuyinto ehamba phambili yethu.Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka.Ngakho-ke, sidinga ukuthi ikhasimende liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcina impahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubheke isithasiselo se-HSSE emigomeni nemibandela yokuthengisa ngezansi).Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.

    2. Indlela yokulethwa

    Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza.Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).

    Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.

    3. Inani elincane le-oda

    Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.

    4.Inkokhelo

    Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.

    5. Amadokhumenti okulethwa

    Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:

    · I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele

    · Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)

    · Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo

    · Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
