ZINTHU ZA MANKHWALA

Mankhwala ndi zinthu zakuthupi zimakhudzidwa kwambiri ndi kuchuluka kwa kachulukidwe, komwe kumakhudzidwa ndi mawonekedwe ndi matayala a unyolo wa maselo.Zipangizo zocheperako zimakhala ndi maunyolo otalikirana komanso otalikirana kwambiri, pomwe zida zolimba kwambiri zimakhala ndi maunyolo owongoka komanso ogwirizana kwambiri.Polyethylene yotsika kwambiri (0.926–0.9409 g/cm3) imasungunuka mu zosungunulira za organic pa kutentha kopitilira 200°F.Ndi insoluble kutentha kwa firiji.Polyethylene yapamwamba kwambiri (0.041-0.965 g/cm3) imakhala ndi hydrophobic, yomwe imatha kulowa m'gasi, ndipo imakhala ndi mphamvu yamagetsi yamagetsi.
Ma polyethylenes otsika kwambiri amakhala ndi mphamvu yolimbana ndi magetsi komanso kukana madzi komanso mankhwala ambiri.Ma polima olemera apakati ndi phula osakanikirana ndi sera ya parafini, ndi ma polima a polyethylene omwe kulemera kwake kwa molekyulu kumakhala kopitilira 10,000 ndi utomoni wodziwika bwino komanso wamphamvu womwe umatha kusintha kapena kuuma.Mwa kusiyanasiyana chothandizira ndi njira zopangira ma polymerization, zinthu monga kachulukidwe, crystallinity, kulemera kwa maselo, ndi polydispersity zitha kuyendetsedwa mosiyanasiyana.Ma polima okhala ndi kachulukidwe kuyambira pafupifupi 0.910 mpaka 0.925 g/cm3 ndi ma polyethylene otsika kwambiri;omwe ali ndi kachulukidwe kuyambira 0.926 mpaka 0.940 g/cm3 ndi polyethylene yapakati-kachulukidwe;ndipo omwe ali ndi kachulukidwe kuyambira 0.941 mpaka 0.965 g/cm3 ndi apamwamba ndi ma polyethylenes okwera kwambiri.

Polyethylene (PE) ndi polima thermoplastic wopangidwa ndi unyolo wautali wa hydrocarbon.PE imagwiritsidwa ntchito pazinthu zingapo kuphatikiza ma CD osinthika opangidwa ndi filimu yowombedwa.Polyethylene imagwiritsidwa ntchito kuwongolera kukhuthala, kuyimitsidwa, komanso kukhazikika kwazinthu zodzikongoletsera.Zomwe zimagwiritsidwa ntchito zimaphatikizira magawo apadera opangidwa ndi jakisoni, m'magawo awa Polyethylene ali ndi ntchito zosiyanasiyana:
Jekeseni ndi kuwomba zoseweretsa zowumbidwa, zida zapakhomo ndi zomangira.
Mipando yamagalimoto yopangidwa ndi jakisoni, zida zotchetcha ndi mapeyala.
Jekeseni wowumbidwa, zotengera zokhala ndi mipanda yopyapyala ndi ziwiya zapakhomo.
Chophimba chotentha chosungunula pamapepala, chowonjezera muzoyikamo, makandulo, inki zokhala ndi mafuta ndi zomatira zotentha zosungunuka.
Zowonjezera ku ma polyesters opanda unsaturated, epoxides ndi ma polima ena kuti apereke mawonekedwe apadera a UHMWPE.Amagwiritsidwa ntchito m'mafakitale, zokutira ndi kuvala pamwamba pa 10-40 wt.%.
Mafilimu omwe ali ndi mawonekedwe abwino komanso osavuta.
Chowonjezera chotulutsa nkhungu, mafuta opangira mphira, extrusion ndi calendering aid ya PVC ndi chithandizo chobalalitsa pakuyika kwamitundu.
Bearings, magiya, bushings ndi zina zosuntha.
machubu a Laboratory;popanga ma prostheses;kusungunula magetsi;zonyamula katundu;khitchini;matanki ndi zitoliro;zokutira mapepala;zomangira nsalu.
polyethylene ntchito kuwongolera mamasukidwe akayendedwe, kuyimitsidwa katundu, ndi bata ambiri mu zodzikongoletsera formulations.Amachokera ku gasi wa petroleum kapena kuchepa kwa mowa.

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)
