Odayi bayinhlanganisela yemvelo enemibala engadaya imicu noma amanye ama-substrates abe nombala othile.Ngokuyinhloko zisetshenziselwa ukudaya ukuphrinta izintambo nezindwangu, ukudaya kwesikhumba, ukudaya amaphepha, izithasiselo zokudla kanye nezinkambu zombala wepulasitiki.Ngokwezindawo zabo nezindlela zokufaka isicelo, odayi bangahlukaniswa babe odayi abahlakazayo, odayi abasebenzayo, odayi be-sulfide, odayi be-VAT, odayi be-asidi, odayi abaqondile nezinye izigaba.
Imakethe enkulu emlandweni ihlobene kakhulu nenani likadayi, futhi intengo kadayi ivamise ukukhuphuka futhi yehle nenani lempahla eluhlaza kanye nokunquma okuhlobene nokunikezwa kanye nesidingo, inenkathi ephakeme ebuthakathaka eqinile isenti.

Imboni ekhuphukayo yomkhakha wokukhiqiza udayi iyimboni ye-petrochemical, imboni yamakhemikhali eyisisekelo kanye nemboni yamakhemikhali wamalahle.Izinto zokusetshenziswa eziyinhloko zodayi yi-benzene, naphthalene, anthracene, heterocycles kanye ne-inorganic acid kanye ne-alkali neminye imikhiqizo yamakhemikhali.Imboni esezansi nomfula iyimboni yokunyathelisa nokudaya embonini yendwangu.

Okuphakathi kodayi kungahlukaniswa ngochungechunge lwe-benzene, uchungechunge lwe-naphthalene kanye nochungechunge lwe-anthracene ngokuya ngesakhiwo sazo, lapho okuphakathi kwe-benzene series esetshenziswa kabanzi.Phakathi kwe-benzene intermediates, i-m-phenylenediamine kanye nama-reductants yizinto ezibalulekile zokusetshenziswa kodayi abahlakazayo, futhi i-para-ester iyimaphakathi eyinhloko yamadayi asebenzayo.Phakathi kwazo, i-m-phenylenediamine ingaphinde ihlanganiswe ibe yi-m-phenylenediamine (ikakhulukazi esetshenziswa njengesibopho sokufakwa kwentambo yesondo) kanye ne-m-aminophenol (udayi ozwela ukushisa/nokucindezela

intermediates).I-Naphthalene intermediates, okuhlanganisa nama-H acids, ayizinto zokusetshenziswa eziyinhloko zokukhiqizwa kodayi abasabelayo, okubalelwa ku-30-50% yenani eliphelele lezindleko.Ngaphezu kwalokho, okuphakathi kokuhlanganisa odayi be-anthraquinone ngokuyinhloko yi-1-amino-anthraquinone. , okungokwesistimu ye-anthraquinone.

Ukuhlaziywa kwamandla amahlanu ka-Porter embonini kadayi 1. Amandla okuxoxisana abahlinzeki bempahla ekhuphuka nomfula abuthaka.Isidingo semboni kadayi ku-petroleum ne-petrochemical commodity cishe sincane kakhulu uma siqhathaniswa nezinye izimboni.Ngakho-ke, imboni kadayi ithola amanani entengo kaphethiloli okhuphuka nomfula kanye nemikhiqizo ye-petrochemical.

2. Amandla okuxoxisana aqinile kumakhasimende angezansi.Amakhasimende angezansi embonini kadayi ikakhulukazi amabhizinisi okuphrinta nokudaya.Amandla okuxoxisana aqinile embonini kadayi kumakhasimende aphansi kakhulu ngenxa yezizathu ezimbili.Okokuqala, ukugxila kwemboni kadayi kuphansi kakhulu.Okwesibili, ezindlekweni zokunyathelisa nokudaya odayi kubalwa amabhizinisi amancane, okunyathelisa nokudaya ukudaya amanani akhuphuka kalula ukuwamukela.

3. Bambalwa abangaba abangenele embonini.Ngenxa yobuchwepheshe belungelo lobunikazi, izinto zokusetshenziswa ezibalulekile kanye nezici zokuvikela imvelo, imboni ye-dyestuff inezithiyo eziphezulu, futhi ukunwetshwa kwamandla okukhiqiza kuvinjelwe.Eminyakeni yamuva, umthamo wokukhiqiza omncane obuyela emuva ususiwe ngenkathi abambalwa abasha abangenayo.Ngakho-ke, imboni yezodayi yesikhathi esizayo iphethini yokugxila ephezulu izokwazi ukuqhubeka.

4. Okushintshwayo kuyingozi encane.Ama-dayi amakhulu angaphandle abeka imikhiqizo ephezulu noma odayi abakhethekile abafaki usongo embonini kadayi yasekhaya.Ukwengeza, ezithintwe amanani entengo kanye nempahla, amanani okuthenga kwamanye amazwe aphakeme uma kuqhathaniswa.Ngenxa yalokho, esikhundleni sikadayi abenzi usongo oluncane.

5. Izinga elimaphakathi lokuncintisana kwezimboni.Ngemva kokuhlanganiswa kwezinga elikhulu lemboni kusukela ngo-2009 kuya ku-2010, inani lamabhizinisi lehlile lafinyelela ngaphezu kwama-300. Ngokuqhubeka nokujula kwezinguquko kuzwelonke, izinga lokugxila kwe Imboni kadayi isithuthuke kakhulu.Umthamo wokukhiqiza udayi wasekhaya wokuhlakazeka ugxile kakhulu eZhejiang Longsheng, Leap Soil Stock kanye neJihua Group, i-CR3 icishe ibe ngama-70%, umthamo wokukhiqiza udayi osebenzayo uphezulu eZhejiang Longsheng, Leap soil Stock, Hubei Chuyuan, Taixing Caragian kanye namabhizinisi amahlanu e-Anoki, i-CR3 icishe ibe ngama-50%.
Ukuqapha kubonisa ukuthi ukungenisa imakethe yezimpahla zesikhathi eside ngaphandle kwesizini kukhuphule intengo yodayi abahlakazayo.Intengo kadayi we-Disperse black ECT300% inyuke ngo-36% ezinyangeni ezimbili ezedlule.

Mayelana nesidingo, ngenxa yomthelela walolu bhubhane, amabhizinisi amaningi endwangu agxile ekuthumeleni kwamanye amazwe e-India adlulisele ama-oda amaningi ekukhiqizweni kwasekhaya ezinyangeni ezisanda kwedlula ngenxa yokungakwazi ukuqinisekisa ukulethwa okuvamile ngenxa yalolu bhubhane.Ngaphezu kwalokho, “Kuphindwe kabili I-11″ iyeza, amabhizinisi e-e-commerce kusenesikhathi, isitokwe siyisihluthulelo sokuwina imakethe.Ngaphezu “kobusika obubandayo” balo nyaka obulindelwe, imboni ithe amabhizinisi endwangu amatasatasa kakhulu manje.Isidingo samadayi akhuphuka nomfula sinyukile. ngokucijile ekuphenduleni.

Mayelana nokuhlinzekwa, isimo esinzima sokuphepha nokuvikelwa kwemvelo e-China singase siqhubeke isikhathi eside esikhathini esizayo ngenxa yokungcoliswa okukhulu okubangelwa ukukhiqizwa kodayi nabaphakathi nendawo, kanye nokuphepha okufanelekile nokuvikelwa kwemvelo umthamo wokukhiqiza osezingeni eliphansi kanye nokungasebenzi kahle. amandla okukhiqiza azoqedwa kancane kancane.I-Guoxin Securities ithe amabhizinisi amancane okukhiqiza udayi ahlakazekile anokukhiqiza okulinganiselwe, isimo samanje sivumela ukuthuthukiswa kwamabhizinisi ahamba phambili odayi.
