Utoto ndi mankhwala achilengedwe omwe amatha kupaka utoto ulusi kapena zinthu zina kukhala mtundu winawake. Amagwiritsidwa ntchito kwambiri popaka utoto wa ulusi ndi nsalu, kupaka utoto wa chikopa, kupaka utoto wa mapepala, zowonjezera chakudya ndi minda ya pulasitiki. Malinga ndi makhalidwe awo ndi njira zogwiritsira ntchito, utotowu ukhoza kugawidwa m'mitundu yosiyanasiyana ya utoto, utoto wosinthika, utoto wa sulfide, utoto wa VAT, utoto wa acid, utoto wolunjika ndi mitundu ina.
Msika waukulu m'mbiri yonse umagwirizana kwambiri ndi mtengo wa utoto, ndipo mtengo wa utoto nthawi zambiri umakwera ndi kutsika ndi mtengo wa zinthu zopangira komanso momwe zinthu zimagwirizanirana ndi kuchuluka kwa zomwe zimafunika, ndipo nyengo yake imakhala yofooka kwambiri.

Makampani opanga utoto wa dyestuff omwe ali pamwamba pa dziko lapansi ndi mafakitale a petrochemical, makampani opanga mankhwala oyambira, ndi makampani opanga mankhwala a malasha. Zipangizo zazikulu zopangira utoto wa dyestuff ndi benzene, naphthalene, anthracene, heterocycles ndi inorganic acid ndi alkali ndi mankhwala ena. Makampani otsatirawa ndi makampani osindikiza ndi dyes m'makampani opanga nsalu.

Mitundu ya utoto ingagawidwe m'magulu a benzene, naphthalene, ndi anthracene malinga ndi kapangidwe kake, ndipo mitundu ya benzene imagwiritsidwa ntchito kwambiri. Pakati pa mitundu ya benzene, m-phenylenediamine ndi reductants ndi zinthu zofunika kwambiri popanga utoto wosakanikirana, ndipo para-ester ndiye mitundu yofunika kwambiri ya utoto wosinthika. Pakati pawo, m-phenylenediamine imatha kupangidwanso kukhala m-phenylenediamine (yomwe imagwiritsidwa ntchito kwambiri ngati chomangira chopangira chingwe cha matayala) ndi m-aminophenol (utoto womvera kutentha/kupanikizika).

zinthu zapakati). Zinthu zapakati za Naphthalene, kuphatikizapo H acids, ndi zinthu zofunika kwambiri popanga utoto wochita kusintha, zomwe zimapangitsa kuti 30-50% ya mtengo wonse ukhalepo. Kuphatikiza apo, zinthu zapakati zopangira utoto wa anthraquinone makamaka ndi 1-amino-anthraquinone, yomwe ndi ya dongosolo la anthraquinone.

Kusanthula kwa mphamvu zisanu kwa Porter pamakampani opanga utoto 1. Mphamvu yogulira zinthu za makampani opanga utoto m'madera otukuka ndi yofooka. Makampani opanga utoto m'madera otukuka ndi benzene, naphthalene ndi makampani ena opanga utoto ndi petrochemical. Kufunika kwa makampani opanga utoto pamafuta ndi petrochemical kuli kochepa poyerekeza ndi mafakitale ena. Chifukwa chake, makampani opanga utoto ndi omwe amalandira mtengo wamafuta ndi petrochemical m'madera otukuka.

2. Mphamvu yogulira zinthu kwa makasitomala otsika mtengo. Makasitomala otsika mtengo m'makampani opanga utoto makamaka ndi makampani osindikiza ndi kupaka utoto. Mphamvu yogulira zinthu kwa makasitomala otsika mtengo makamaka ndi chifukwa cha zifukwa ziwiri. Choyamba, kuchuluka kwa makampani opanga utoto ndi kochepa kwambiri. Chachiwiri, mtengo wosindikizira ndi kupaka utoto unali wochepa, ndipo mitengo ya makampani osindikiza ndi kupaka utoto imakwera mosavuta.

3. Ochepa omwe angathe kulowa mumakampaniwa. Chifukwa cha ukadaulo wa patent, zinthu zofunika kwambiri zopangira, komanso zinthu zoteteza chilengedwe, makampani opanga utoto ali ndi zopinga zambiri, ndipo kukula kwa mphamvu zopangira kuli kocheperako. M'zaka zaposachedwa, mphamvu zochepa zopangira zachotsedwa pomwe ochepa atsopano alowa. Chifukwa chake, njira yamtsogolo yopangira utoto idzatha kupitilira.

4. Zosintha sizili pachiwopsezo chachikulu. Makampani akuluakulu opaka utoto akunja omwe amaika zinthu zapamwamba kapena utoto wapadera sali pachiwopsezo ku makampani opanga utoto am'deralo. Kuphatikiza apo, chifukwa cha mitengo yamitengo ndi katundu, mitengo yochokera kunja imakhala yokwera kwambiri. Chifukwa cha izi, zosinthira utoto sizili pachiwopsezo chachikulu.

5. Mpikisano wapakati pamakampani. Pambuyo pa kuphatikiza kwakukulu kwa makampani kuyambira 2009 mpaka 2010, chiwerengero cha mabizinesi chatsika kufika pa 300. Chifukwa cha kukulirakulira kwa kusintha kwa dziko lonse, kuchuluka kwa makampani opanga utoto kwakula kwambiri. Mphamvu zopangira utoto wofalikira m'nyumba makamaka ku Zhejiang Longsheng, Leap Soil Stock ndi Jihua Group, CR3 ili pafupifupi 70%, mphamvu zopangira utoto wosinthika ndi yayikulu ku Zhejiang Longsheng, Leap soil Stock, Hubei Chuyuan, Taixing Caragian ndi mabizinesi asanu a Anoki, CR3 ili pafupifupi 50%.
Kuwunika kukuwonetsa kuti kubweretsa msika wa zovala zomwe sizinali za nyengo yayitali kunakweza mwachindunji mtengo wa utoto wofalikira. Mitengo ya utoto wakuda wa Disperse ECT300% yakwera ndi 36% m'miyezi iwiri yapitayi.

Ponena za kufunikira, chifukwa cha zotsatira za mliriwu, makampani ambiri akuluakulu otumiza nsalu ku India atumiza maoda ambiri kuzinthu zopangidwa m'nyumba m'miyezi yaposachedwa chifukwa cholephera kutsimikizira kuti zinthuzo zifika bwino chifukwa cha mliriwu. Kuphatikiza apo, "Double 11" ikuyandikira, makampani ogulitsa pa intaneti akuyitanitsa pasadakhale, masheya ndiye chinsinsi chopambana msika. Kuphatikiza pa "nyengo yozizira" yomwe ikuyembekezeka chaka chino, makampaniwa adati makampani opanga nsalu ali otanganidwa kwambiri tsopano. Kufunika kwa utoto wokwera kwakweranso kwambiri poyankha.

Ponena za kupezeka, vuto lalikulu la chitetezo ndi kuteteza chilengedwe ku China likhoza kupitirira kwa nthawi yayitali mtsogolo chifukwa cha kuipitsidwa kwakukulu komwe kumachitika chifukwa cha kupanga utoto ndi zinthu zina, ndipo chitetezo choyenera ndi kuteteza chilengedwe mphamvu zopangira zosakwanira komanso mphamvu zopangira zosagwira ntchito bwino zidzachotsedwa pang'onopang'ono. Guoxin Securities inati makampani opanga utoto ang'onoang'ono ali ndi kupanga kochepa, zomwe zikuchitika pano zimathandiza kuti makampani opanga utoto azikula.
