Chengetedza muimba yekuchengetera inotonhorera uye ine mhepo.Ramba kure nepfarivari uye kunopisa kupisa.Kupisa kweimba yekuchengetera hakufanirwe kudarika 30 ℃.Inofanira kuchengetwa zvakasiyana kubva kune oxidants, acids, uye halogens, uye haifaniri kusanganiswa kuti ichengetedzwe.Kushandisa chiedza chinoputika-chisingapindi chiedza uye nzvimbo dzekupinza mhepo.Rambidza kushandiswa kwemichina uye maturusi ari nyore kupfuta.Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa nemichina yekupindura nechimbichimbi painodonha.
Paunenge uchitakura simbi dzesimbi, zvinodikanwa kupfeka helmete yekuchengetedza pane cylinder.Simbi dzesimbi dzinowanzoiswa dzakafuratira, uye muromo webhodhoro unofanirwa kutarisana negwara rimwe chete uye kwete kuyambuka;Kureba hakufaniri kudarika fence yekudzivirira yemotokari, uye mapadhi emapuranga ane katatu anofanirwa kushandiswa kuichengetedza kudzivirira kukunguruka.Panguva yekufambisa, mota dzekufambisa dzinofanirwa kunge dzakashongedzerwa nemhando dzinoenderana uye huwandu hwemidziyo yekudzima moto.Iyo pombi yekupisa yemotokari inotakura chinhu ichi inofanirwa kunge ine murazvo wemoto unodzoreredza mudziyo, uye inorambidzwa kushandisa michina michina uye midziyo inotarirwa nepfarivari yekurodha nekuburitsa.Zvinorambidzwa zvachose kusanganisa uye kutakura neoxidants, acids, halogens, makemikari anodyika, etc. Kutakura kunofanira kuitwa mangwanani uye manheru muzhizha kudzivirira kubuda kwezuva.Panguva yekumira, gara kure nepfarivari uye zvinopisa.Munguva yekufambisa mumugwagwa, zvinodikanwa kutevedzera nzira yakatemwa uye kumira munzvimbo dzekugara uye dzine vanhu vakawanda.Inorambidzwa kutsvedza panguva yekufambisa njanji.
Dimethyl ether, seyakasimukira organic makemikari raw material, ine akawanda akasiyana mashandisirwo mumishonga, mafuta, mushonga wezvipembenene uye mamwe maindasitiri emakemikari nekuda kwekunakisisa kwayo kusimba, condensation, uye gasification maitiro.High kuchena dimethyl ether inogona kutsiva Freon seaerosol pfapfaidzo uye refrigerant, kuderedza kusvibiswa kune nharaunda yemhepo uye ozone layer kukuvara.Nekuda kwekunyungudika kwayo kwemvura uye kunyungudika kwemafuta, huwandu hwayo hwekushandisa hwakakwirira zvakanyanya kumakemikari epetroleum akadai sepropane uye butane.Kutsiva methanol sechinhu chitsva chekugadzirwa kwe formaldehyde kunogona kuderedza zvakanyanya mutengo wekugadzirwa kwe formaldehyde uye kuratidza hukuru hwayo muzvirimwa zvakakura zve formaldehyde.Segasi remafuta echivanhu, zviratidziro zvaro zvakaita sekuchengetedza uye kufambisa, kuchengetedzwa kwekupisa, premixed gasi calorific kukosha, uye tembiricha yekupisa tembiricha yakakwira kune iyo yakanyungudutswa petroleum gasi.Inogona kushandiswa senge peak yekuveura gasi kune yemudhorobha pombi gasi uye musanganiswa weliquefied petroleum gasi.Iyo zvakare mafuta akakodzera einjini dzedhiziri, uye kana ichienzaniswa nemota dzemethanol, hapana dambudziko nekutonhora kutanga kwemota.Dimethyl ether zvakare imwe yezvinhu zvakakosha zvekugadzirwa kweiyo low-carbon olefins mune ramangwana.
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)
