Kushandiswa kwedhayi kunoita kuti hupenyu hwevanhu huve neruvara.

Kubva pazvipfeko pamuviri, bhegi rekuchikoro kumusana, sechirafu chekushongedza, tayi, inowanzoshandiswa mumicheka yakarukwa, machira akarukwa uye zvigadzirwa zvefiber, zvidhaye nemavara matsvuku, ero, epepuru uye ebhuruu.
Muchidimbu, semusanganiswa wezvakagadzirwa, dhayi, mumamorekuru kana yakapararira, inopa zvimwe zvinhu ruvara rwakajeka uye rwakasimba.

Muchidimbu, kuparadzira dhayi imhando yedhayi isiri-ionic ine yakaderera mvura solubility.

Yayo molecular chimiro chiri nyore, solubility yakaderera, kuitira kuti ikwanise kupararira zvakanaka mumhinduro, kunze kwekukuya kune isingasviki 2 microns, inodawo kuwedzera yakawanda inoparadzira, kuitira kuti iparadzire. mune mhinduro zvakadzikama.Saka, rudzi urwu rwedhayi runozivikanwa zvakanyanya se "disperse dye".

Inogona kukamurwa zvakaenzana kuita disperse orenji, kuparadzira yero, kuparadzira bhuruu, kuparadzira tsvuku uye zvichingodaro, mavara akati wandei maererano nechiyero chakasiyana, anogonawo kuwana mamwe mavara.Kuenzaniswa nemamwe madhayi, dhayi dhayi ndiyo inonyanya kushandiswa uye imwe ye iyo inonyanya kukosha dhayi.

Nekuda kwekushandiswa kwakawanda kwekuparadzira dhayi, kushanduka kwemitengo yezvinhu zvayo zvakabikwa uye zvigadzirwa zvinokanganisawo kukurumidza kugadziriswa kwemutengo wekugovana wemakambani akanyorwa akakodzera.

Musi waKurume 21, 2019, kuputika kwakaitika paxiangshui Chenjiagang Tianjiayi Chemical Factory muYancheng. CPC Central Committee uye State Council vakakoshesa zvikuru kuputika uku. Dunhu reJiangsu uye madhipatimendi akakodzera ari kuita nepaanogona napo kununura uye kununura vanhu kubva kumativi ese ehupenyu vari kunamatira Xiangshui.

Mushure mekuputika, mapaki eindasitiri yemakemikari munyika yese akatanga mabasa ekuongorora kuchengetedza munguva yenjodzi. Shaoxing Shangyu, dhorobha guru rekugadzira dhayi, rakatangawo ongororo yekuchengetedzwa kwedunhu, izvo zvinozoita kuti mabhizinesi emakemikari munyika yese aridza aramu uye anofanirwa kushanda zvakachengeteka.

Mishonga mikuru yemiti yemakemikari inosanganisira disperse dyes uye mamwe madhayi anogadzirisa, akananga madhayi epakati - m-phenylenediamine.

Mushure mekuputika, mabhizinesi akasiyana siyana ekuparadzira dhayi uye vagadziri vepakati vakamira kugamuchira maodha, zvichitungamira mukushomeka kwem-phenylenediamine, iyo inosungirwa kukwidza kukwira kwemitengo yezvigadzirwa zvedhayi.

Mutengo wemusika wem-phenylenediamine wakawedzera zvakapetwa kaviri kubva munaKurume 24, uye kusanganiswa kwekushomeka kwemasheya uye kurova kwehuwandu hwekugadzira kuchasundira kuparadzira mitengo yedhayi kumusoro.
Uye vashoma vedzimba vanoparadzira dhayi makambani akagovera mitengo yakakwira uye yakaderera, hazvina kuoma kunzwisisa.Asi kushata kwekuparadzira dhayi hakusi chiitiko chinongoitika mumakore achangopfuura, uye vanhu vagara vachiziva nezvekusagadzikana kwemutengo wayo wemari. .

➤ Kubva pamaonero emakwikwi emusika, musika wedhayi wakapararira zvishoma nezvishoma wakagadzira mamiriro emakwikwi emusika we oligopoly, ukuwo kudiwa kwedhayi dzekuparadzira kwakagadzikana. Kuwedzera kwekusangana kwemusika wedhayi kuchakanganisa kuwanikwa kwemusika uye kudiwa, kuvandudza simba rekutengesa revatengesi, uyezve kusimudzira kukwira kwemutengo wemusika wedhayi.

Muna 2018, mashandiro emakambani akanyorwa ane dhayi akapararira aive nani, uye muna 2019, kana mashandiro acho achiramba achikura, kukwira kwemutengo wechigadzirwa ndiyo yakananga uye inoshanda chiyero.

Kune rimwe divi, nekuda kwekuchengetedzwa kwezvakatipoteredza kutanga, izvi zvichatungamira zvakare kuparadzira chigadzirwa chedhayi mitengo icharamba ichienderera mberi ichimhanya.Kwete chete kuchengetedza kwezvakatipoteredza manejimendi inodhura, senge nguva nenguva kugadziridzwa kwekugadzira muganhu kuchakanganisa kugoverwa kwemusika wedhayi. .

Kunyangwe mamwe mabhizinesi ekuparadzira dhayi akambomira kugadzirwa anozotangazve kugadzira zvishoma nezvishoma, zvinowanzoitika kuti kubuda chaiko kwemabhizinesi ekubereka kudiki kwazvo pane izvo zvisati zvamiswa kugadzirwa.

Hondo yakaoma yekurwisa kusvibiswa ichasundidzira mamwe maindasitiri ane simba rakawandisa kuti abvise, uye indasitiri yedhayi ichine nzira refu yekuenda.
