    Chigadzirwa molecular chimiro:

    phenolic resin

    CHEMICAL PROPERTIES

    Phenol-formaldehyde resin inogadzirwa nenzira inotevera:
    C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
    Imwe-Stage Resins.Chiyero che formaldehyde kune phenol chakakwira zvakakwana kubvumira iyo thermosetting process kuti iitike pasina kuwedzera kwemamwe masosi e-cross-link.
    Matanho maviri Resins.Huyero ye formaldehyde kune phenol yakadzikira zvakakwana kudzivirira iyo thermosetting reaction kubva kuitika panguva yekugadzirwa kweresin.Panguva iyi resin inonzi novolac resin.Zvadaro, hexamethylenetetramine inobatanidzwa mune zvinyorwa kuti iite sechitubu chemakemikari e-cross-link panguva yekuumbwa kwekushanda (uye kutendeuka kune thermoset kana kuporesa nyika).

    APPLICATION AREA

    Pharmaceutical
    Indasitiri yemafuta
    Mushonga wezvipembenene
    Diesel Engine Fuel
    Refrigerant
    Aerosol Spray

    Phenolic resins inoshandiswa kune yakaderera-mutengo zvikamu zvinoda yakanaka magetsi insulating zvivakwa, kupisa kupisa, kana makemikari kuramba.Avhareji yehupenyu hwesherufu yeresin iyi ingangoita mwedzi mumwe pa21.1°C.Izvi zvinogona kuwedzerwa nekuichengeta mufiriji pa1.6 kusvika 10°C.Kusiyanisa iyo catalyst (maererano nehukobvu hwekukandira) uye kukwidza tembiricha yekurapa kusvika 93 ° C kuchachinja nguva yekurapa kubva kureba se8h kusvika kupfupi se15 min.
    Imwe shrinkage inoitika mukukandwa kwakapedzwa (0.012 kusvika 0.6 mm/mm), zvichienderana nehuwandu hwekuzadza, huwandu hwezvinokonzeresa, uye chiyero chekurapa.Kurumidza kurapa kutenderera kunounza mwero wepamusoro we shrinkage.Sezvo kutenderera kwekurapa kunogona kukwidziridzwa, phenolics anoshandiswa mukupfupi-runcasting mashandiro.
    Cast phenolic zvikamu zvinobviswa zviri nyore kubva muforoma kana maajenti ekuparadzanisa anokurudzirwa nemupi akashandiswa.Posteuring inovandudza thebasic zvimiro zvekupedzwa kukanda.

    ZVINOITENGA KUBVA KWAtiri

    Chemwin inogona kupa huwandu hwakawanda hwemahydrocarbon akawanda uye makemikari zvinonyungudutsa kune vatengi vemaindasitiri.Izvi zvisati zvaitika, ndapota verenga zvinotevera ruzivo rwekuita bhizinesi nesu: 

    1. Chengetedzo

    Chengetedzo ndiyo inonyanya kukosha kwatiri.Pamusoro pekupa vatengi ruzivo nezve mashandisiro akachengeteka uye ane hushamwari ezvigadzirwa zvedu, isu takazvipirawo kuona kuti njodzi dzekuchengetedza dzevashandi nemakondirakiti dzadzikiswa kuita shoma inonzwisisika uye inogoneka.Naizvozvo, isu tinoda kuti mutengi ave nechokwadi chekuti kurodha kwakakodzera uye kuchengetedza kuchengetedza zviyero zvinosangana tisati tasvitsa (ndapota tarisa kune HSSE appendix muhuwandu hwematemu uye mamiriro ekutengesa pazasi).Nyanzvi dzedu dzeHSSE dzinogona kupa gwara pane aya mazinga.

    2. Delivery nzira

    Vatengi vanogona kuraira uye kuendesa zvigadzirwa kubva kuchemwin, kana kuti vanogona kugamuchira zvigadzirwa kubva kune yedu kugadzira chirimwa.Nzira dziripo dzekutakura dzinosanganisira rori, njanji kana multimodal kutakura (zvakasiyana mamiriro anoshanda).

    Panyaya yezvinodiwa nevatengi, tinogona kutsanangura zvinodikanwa zvemabhaji kana matangi uye kushandisa yakakosha kuchengetedza / kuongorora zviyero uye zvinodiwa.

    3. Minimum order yakawanda

    Kana iwe ukatenga zvigadzirwa kubva pawebhusaiti yedu, iyo yakaderera odha huwandu i30 matani.

    4.Payment

    Iyo yakajairika nzira yekubhadhara inobviswa zvakananga mukati memazuva makumi matatu kubva painvoice.

    5. Delivery zvinyorwa
