Madhayi ane mavara maorganic compounds anogona kudhayi faibha kana mamwe masubstrates mune rumwe ruvara. Iwo anonyanya kushandiswa mukudhinda kudhindwa kweshinda uye machira, dhayi rematehwe, dhayi mapepa, zvinowedzera zvekudya uye minda yepurasitiki yemavara. Maererano nemidziyo yavo uye nzira dzekushandisa, dhayi dzinogona kukamurwa kuita madhayi anoparadzira, dhayi reactive, sulfide dhayi, VAT dhayi, madhayi ane acid, madhayi akananga uye mamwe marudzi.
Musika mukuru munhoroondo unonyanya kuenderana nemutengo wedhayi, uye mutengo wedhayi unowanzo kukwira uye uchidonha nemutengo wezvigadzirwa pamwe nekupa uye hukama hwekudiwa hunosarudza, ine mwaka wakasimba usina simba wepamusoro cent.

Indasitiri yekumusoro yeindasitiri yekugadzira dhayi iindasitiri yepetrochemical, indasitiri yemakemikari ekutanga uye indasitiri yemakemikari emarasha. Iyo mikuru yezvigadzirwa zvedhayi ndeye benzene, naphthalene, anthracene, heterocycles uye inorganic acid uye alkali uye zvimwe zvigadzirwa zvemakemikari. Indasitiri yepasi iindasitiri yekudhinda nekudhaya muindasitiri yemachira.

Dye intermediates inogona kupatsanurwa kuita benzene series, naphthalene series uye anthracene series zvichienderana nechimiro chazvo, pakati peiyo benzene series intermediates inoshandiswa zvakanyanya.Pakati pebenzene intermediates, m-phenylenediamine uye reductants ndiwo akakosha mambishi ekugadzirwa kwedhayi. uye para-ester ndiyo yakakosha yepakati yeanoshanda dhayi. Pakati pazvo, m-phenylenediamine inogona zvakare kugadzirwa kuita m-phenylenediamine (inonyanya kushandiswa sebhainda rekutangisa tambo yetambo) uye m-aminophenol (kupisa/kudzvanya dhayi.

intermediates).Naphthalene intermediates, kusanganisira H acids, ndiwo musimboti wezvigadzirwa zvekugadzira dhayi reactive, zvichiverengera 30-50% yemutengo wakakwana. Pamusoro pezvo, zvepakati pakuumbwa kwedhayi anthraquinone zvakanyanya 1-amino-anthraquinone. , iyo ndeye anthraquinone system.

Porter's five forces ongororo yeindasitiri yedhayi 1. Simba rekutengesa kwevanotengesa dhayi riri kukwira harina kusimba.Vatengesi veindasitiri yedhayi vari kumusoro vari benzene, naphthalene nemamwe vatengesi vepetroleum nepetrochemical commodity. Kudiwa kweindasitiri yedhayi kwepetroleum uye petrochemical commodity kunenge kushomeka kana zvichienzaniswa nemamwe maindasitiri. Naizvozvo, indasitiri yedhayi ndiyo inogamuchira mutengo wepamusoro petroleum uye petrochemical zvigadzirwa.

2. Simba rekutengeserana rakasimba kune vatengi vari pasi.Vatengi vepasi vemabhizimisi edhayi vanonyanya kudhinda uye kudhaya mabhizinesi. Simba rekutengesa rakasimba reindasitiri yedhayi kune vatengi vepasi rinonyanya kukonzerwa nezvikonzero zviviri. Chekutanga, kusangana kweindasitiri yedhayi kwakadzikira.Chechipiri, mumutengo wekudhinda uye kudhaya madhayi akaverengera madiki, kudhinda uye dhayi mabhizinesi ekudhaya mitengo inokwira nyore kugamuchira.

3. Vashoma vanogona kupinda muindastiri.Nekuda kwe tekinoroji yematekinoroji, zvinhu zvakakosha zvakasvibirira uye kuchengetedzwa kwezvakatipoteredza, indasitiri yedhayi ine zvipingamupinyi zvakakwirira, uye kuwedzera kwesimba rekugadzira kunorambidzwa. Mumakore achangopfuura, kumashure madiki ekugadzira madiki akabviswa nepo vashoma vatsva vakapinda.Saka, remangwana dhayi indasitiri high concentration maitiro achakwanisa kuenderera.

4. Vatsivi vanoisa tyisidziro shoma.Kune dhayi hofori dzinoisa zvigadzirwa zvepamusoro-soro kana dhayi dzakakosha hadzisi njodzi kune indasitiri yedhayi. Pamusoro pezvo, zvakakanganiswa nemitero uye kutakura zvinhu, mitengo yekunze yakakwira zvishoma.Nekuda kweizvozvo, zvinotsiva dhayi hazvikonzeri njodzi.

5. Chiyero chiri pakati nepakati chemakwikwi emaindasitiri.Mushure mekubatanidzwa kukuru kweindastiri kubva 2009 kusvika 2010, huwandu hwemabhizinesi hwadzikira kusvika kupfuura mazana matatu. Indasitiri yedhayi yakavandudzika zvakanyanya.Domestic disperse dhayi kugadzirwa kwesimba kunonyanya kuiswa muZhejiang Longsheng, Leap Soil Stock uye Jihua Group, CR3 inenge 70%, reactive dhayi kugadzira dhayi yakakwira muZhejiang Longsheng, Leap ivhu Stock, Hubei Chuyuan, Taixing Caragian. uye Anoki mabhizinesi mashanu, CR3 ingangoita 50%.
Monitoring inoratidza kuti yakaunza musika wembatya wenguva refu kunze kwemwaka yakananga kukwidza mutengo wekuparadzira dhayi.Disperse black ECT300% mitengo yedhayi yakakwira 36% mumwedzi miviri yadarika.

Panyaya yekuda, nekuda kwekukanganisa kwedenda, mabhizinesi mazhinji makuru ezvipfeko eIndia akatamisa maodha akawanda mukugadzirwa kwepamba mumwedzi ichangopfuura nekuda kwekusakwanisa kuvimbisa kutakura kwakajairika nekuda kwedenda. 11 ″ iri kusvika, e-commerce mabhizinesi pamberi, stock ndiyo kiyi yekuhwina musika.Kuwedzera kune gore rino "chando chinotonhora" chinotarisirwa, indasitiri yakati mabhizinesi emachira ari kunyanya kubatikana izvozvi.Kudiwa kwedhayi dzekumusoro kwasimukawo zvakasimba mukupindura.

Panyaya yekugovera, mamiriro akaomarara ekuchengetedza nekuchengetedzwa kwezvakatipoteredza muChina anogona kuenderera mberi kwenguva yakareba mune ramangwana nekuda kwekusvibiswa kukuru kunokonzerwa nekugadzirwa kwedhayi nepakati, uye kuchengetedzwa kwakakodzera nekuchengetedzwa kwezvakatipoteredza kugadzirwa kwepasi uye kusashanda. kugadzirwa kwemagetsi kuchabviswa zvishoma nezvishoma.Guoxin Securities yakati mabhizinesi madiki-diki anoparadzira dhayi ane mashoma ekugadzirwa, mamiriro ezvinhu aripo anobatsira mukuvandudza dhayi inotungamira mabhizinesi.
