Chigadzirwa molecular chimiro:
Calcium carbide (morekuru fomula: CaC2), imhando yemakemikari akakosha ezvigadzirwa anogadzirwa kubva kumakemikari kugadzirisa limestone.Muna 1892, H. Maysan (French) naH. Wilson (United state) panguva imwe chete vakagadzira nzira yekugadzira calcium carbide inobva pamoto Kuderedza.Nyika yeUnited States yakanga yabudirira kubudirira mukugadzirwa kwemaindasitiri muna 1895. Nzvimbo ye calcium carbide inoenderana nekuchena kwayo.Chigadzirwa chayo cheindasitiri chinowanzo musanganiswa we calcium carbide uye calcium oxide, uye zvakare ine inoteedzera huwandu hwesarufa, phosphorus, nitrogen uye humwe hutsvina.Nekuwedzera kuri kuita tsvina, ruvara runoratidza grey, brown kusvika kune dema.Iyo yekunyungudika uye conductivity yemagetsi zvese zvinodzikira nekudzikira kwekuchena.Kuchena kwechigadzirwa chayo cheindasitiri kazhinji 80% ine mp iri 1800 ~ 2000 °C.Patembiricha yemumba, haiite nemhepo, asi inogona kuve neoxidation reaction iri pamusoro pe350 ℃, uye kuita nenitrogen pa600 ~ 700 ℃ kugadzira calcium cyanamide.Calcium carbide, kana ikauya nemvura kana chiutsi, inogadzira acetylene uye inoburitsa yakawanda yekudziya.CaC2 + 2H2O─ → C2H2 + Ca (OH) 2 + 125185.32J, 1kg ye pure calcium carbide inogona kubudisa 366 L yeacetylene 366l (15 ℃, 0.1MPa).Nokudaro, nokuda kwekuchengetedza kwayo: calcium carbide inofanira kunyatsochengetwa kure nemvura.Inowanzo kutakurwa mumudziyo wesimbi wakavharwa, uye dzimwe nguva inochengetwa mudura rakaoma ichizadzwa nenitrogen kana zvichidikanwa.
Calcium carbide (CaC2) ine kunhuhwirira kwakafanana negariki uye inopindirana nemvura kuita gasi reacetylene pamwe necalcium hydroxide uye kupisa.Kare, yaishandiswa mumarambi evacheri kuti irambe ichiburitsa murazvo weacetylene kuti upe kumwe kuvhenekera mumigodhi yemarasha.
Calcium carbide inoshandiswa sedesulfurizer, dehydrant yesimbi, mafuta mukugadzira simbi, ine simba deoxidizer uye sechitubu cheacetylene gasi.Inoshandiswa sechinhu chekutanga chekugadzira calcium cyanamide, ethylene, chloroprene rubber, acetic acid, dicyandiamide uye cyanide acetate.Inoshandiswa mumarambi ecarbide, zvidhori zvematoyi senge big-bang cannon uye bamboo cannon.Iyo inosanganiswa necalcium phosphide uye inoshandiswa mukuyangarara, inozvibatidza yemvura chiratidzoCalcium carbide ndiyo inonyanya kukosha carbide mumaindasitiri nekuda kwebasa rayo rakakosha sehwaro hweindasitiri yeacetylene.Munzvimbo dzine kushomeka kwepetroleum, Calcium Carbideinoshandiswa sechinhu chekutanga chekugadzirwa kweacetylene (1 kg yegoho re carbide ~ 300 litres acetylene), iyo, iyo, inogona kushandiswa sechivako chekuvaka kune zvakasiyana-siyana zvemakemikari emakemikari (eg vinyl acetate, acetaldehyde uye acetic acid. )Mune dzimwe nzvimbo, acetylene inoshandiswawo kugadzira vinyl chloride, iyo mbishi yekugadzirwa kwePVC.
Kushandiswa kushoma kwe Calcium Carbide zvinoenderana neindasitiri yemaferiza.Inopindirana nenitrogen kugadzira calcium cyanamide, inova ndiyo yekutanga kugadzirwa kwecyanamide (CH2N2).Cyanamide chigadzirwa chakajairika chekurima chinoshandiswa kukurudzira kutanga kwefoliation.
Calcium Carbide inogona zvakare kushandiswa sedesulfurizing agent yekugadzira yakaderera-sarufa kabhoni simbi.Zvakare, inoshandiswa sechinhu chinodzikisira kugadzira simbi kubva mumunyu wavo, semuenzaniso, kudzikisa zvakananga copper sulfide kuita metallic mhangura.flares.Uyezve, inobatanidzwa mukuderedzwa kwemhangura sulfide kune metallic mhangura.
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)
