chena kusvika kuchiedza cheyero flakes kana makristasi
Diphenylmethane-4,4-disocyanate (MDI) inoshandiswa zvakanyanya mukugadzirwa kwezvakaoma urethane foam zvigadzirwa, machira, andelastomers.
Diphenyl methane diisocyanate (MDI) inoshandiswa zvakanyanya mu polyurethane coatings, chigadzirwa ichi chinogadzirwa ne polyurethane foam inoshandiswa seinodziya (inotonhora), zvinhu zvekuvaka, motokari, zvikamu zvechikepe;masterwork inogona kugadzira mota Block, buffer, synthetic dehwe, isiri purasitiki polyurethane, polyurethane elastic fiber, isina epurasitiki elastic fibers, mafirimu, anonamira.
Diphenylmethane-4,4-disocyanate inoshandiswa mukugadzira polyurethane resin uye Spandex fibers;kusungirirwa kwerabha kune rayon;diisoeyanate mukugadzirwa kwepolyurethane lacquers, furo mapurasitiki, rabha, uye glues.
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
Mapepa anotevera anopiwa kune imwe neimwe yekutumira:
· Bill of Lading, CMR Waybill kana rimwe gwaro rekufambisa rakakodzera
· Sitifiketi Yekuongorora kana Conformity (kana zvichidikanwa)
· Zvinyorwa zvine chekuita neHSSE zvinoenderana nemitemo
· Zvinyorwa zvetsika zvinoenderana nemirairo (kana zvichidikanwa)
