Chigadzirwa molecular chimiro:
Benzene imvura yakajeka, inoputika, isina ruvara, inopfuta zvakanyanya ine kunhuhwirira kunofadza.I hydrocarbon inonhuhwirira inovira pa80.1 DC.Benzene inoshandiswa sechinhu chinonyungudutsa munzvimbo dzakawanda dzemaindasitiri, sekugadzira rabha uye shangu, uye mukugadzirwa kwezvimwe zvinhu zvakakosha, se styrene, phenol, uye cyclohexane.Yakakosha mukugadzira mishonga yekugeza, mishonga yezvipembenene, zvinonyungudutsa, uye zvekubvisa pendi.Inowanikwa mumafuta akadai sepeturu kusvika pachikamu che5%.
Yakajeka, isina ruvara kusvika kuchiedza yero yemvura mvura ine inonhuwirira, musty, phenolics kana peturu-kunhuwa.Pa40 ° C, kunhuhwirira kwemukati kwe190 μg / L mumhepo kwakatemwa naYoung et al.(1996).Chikumbaridzo chekunhuwa che4.68 ppmv chakatemwa naLeonardos et al.(1969).Kuonekwa kunhuhwirira kwe108 mg / m3 (34 ppmv) kwakashumwa naPunter (1983).Avhareji isingaonekwi kunhuwa kwemukati mumvura pa60 ° C uye mumhepo pa40 ° C yaive 0.072 uye 0.5 mg/L, zvichiteerana.
Benzene zvakare inoshandurwa kuita cyclohexane, iyo inoshandiswa kugadzira nylon uye mafibhi ekugadzira.
Benzene inowanikwa mumarasha uye marasha-tara distillation zvigadzirwa uye mune petroleum zvigadzirwa sepeturu.Inowanikwawo mumagasi uye maburi emarara emarara emaindasitiri, marara ekuvaka, uye marara enzvimbo (Oak Ridge National Laboratory 1989).Zviyero zvebenzene, toluene, xylenes, nezvimwe zvipenyu zvinoputika zvakawanikwa muivhu nemumvura yepasi pedyo nenzvimbo zhinji dzesainitarylandfills (US EPA 1989a,b).Kramer(1989) akaongorora mwero weexposuresto benzene panguva yekubvisa, kuchenesa, kupomba, uye kuyedzwa matangi epasi pevhu ekuchengetera peturu.Avhareji yekuratidzwa kwevanhu 0.43-3.84 ppm (mumaawa 1.5-6) uye yakanyanya kupfupika kwenguva pfupi (15-maminitsi) kuratidzwa yaive9.14 ppm.Benzene inowanikwawo mufodya (Hoffmann et al. 1989);nokudaro njodzi yekuratidzwa kwayo inogona kuwedzera kubva mukufema utsi hwakadaro.
Benzene inoshandiswa sechinhu chinonyungudutsa chewakisi, resin, nemafuta;sechinobvisa pendi;se diluentfor lacquers;mukugadzira dhayi, mishonga, mavhanishi, uye linoleum; uye sechinhu chisina kubikwa kugadzira akawanda eorganic compounds.
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)
