    ZINTHU ZA MANKHWALA

    Tetrahydrofuran (THF) ndi madzi opanda mtundu, osasunthika okhala ndi fungo la ethereal kapena acetone ndipo amasanganikirana m'madzi ndi zosungunulira zambiri za organic. Ndiwotentha kwambiri ndipo amatha kuwola ndikukhala carbon monoxide ndi carbon dioxide.Kusungidwa kwanthawi yayitali pakukhudzana ndi mpweya komanso ngati palibe antioxidant kungayambitse THF kuwola kukhala ma peroxides ophulika.

    Tetrahydrofuran imagwiritsidwa ntchito popanga ma polima komanso mankhwala aulimi, mankhwala, komanso mankhwala.Ntchito zopanga zinthu nthawi zambiri zimachitika m'makina otsekedwa kapena pansi paulamuliro wa uinjiniya womwe umachepetsa kuwonekera kwa ogwira ntchito ndikumasulidwa ku chilengedwe.THF imagwiritsidwanso ntchito ngati zosungunulira (mwachitsanzo, kuyika chitoliro) zomwe zingapangitse kuti pakhale zowonekera kwambiri zikagwiritsidwa ntchito m'malo otsekeka popanda mpweya wokwanira.Ngakhale THF imapezeka mwachilengedwe mu fungo la khofi, nandolo zophikidwa ufa, ndi nkhuku yophika, kuwonetseredwa kwachilengedwe sikuyembekezeredwa kubweretsa ngozi yayikulu.

    APPLICATION AREA

    Zamankhwala
    Mafuta amafuta
    Mankhwala ophera tizilombo
    Mafuta a Dizilo
    Refrigerant
    Aerosol Spray

    Butylene oxide imagwiritsidwa ntchito ngati fumigant komanso kusakanikirana ndi mankhwala ena.Amagwiritsidwa ntchito kuti akhazikitse mafuta pokhudzana ndi mapangidwe amtundu ndi matope.

    Tetrahydrofuran imagwiritsidwa ntchito ngati zosungunulira za forresins, vinyls, ndi ma polima apamwamba;monga Grignardreaction sing'anga kwa organometallic, ndi zitsulo hydride zochita;komanso mu kaphatikizidwe ka succinic acid ndi butyrolactone.

    Tetrahydrofuran amagwiritsidwa ntchito makamaka (80%) kupanga polytetramethylene etha glycol, polima m'munsi ntchito makamaka kupanga elastomeric ulusi (mwachitsanzo, spandex) komanso polyurethane ndi poliyesitala elastomers (mwachitsanzo, chikopa yokumba, mawilo skateboard).Zotsalazo (20%) zimagwiritsidwa ntchito pa zosungunulira (mwachitsanzo, simenti za chitoliro, zomatira, inki zosindikizira, ndi tepi ya maginito) komanso monga zosungunulira mu mankhwala ndi mankhwala.

    MMENE MUNGAGULE KWA IFE

    Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe: 

    1. Chitetezo

    Chitetezo ndicho chofunikira kwambiri chathu.Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka.Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa).Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.

    2. Njira yobweretsera

    Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga.Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).

    Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.

    3. Kuchuluka kwa dongosolo lochepa

    Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.

    4.Kulipira

    Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.

    5. Zolemba zotumizira

    Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:

    · Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe

    · Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)

    · Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo

    · Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
