Warshadaha chlor-alkali waa warshado kiimiko oo aasaasi ah oo muhiim ah, iyo wax soo saarka ugu muhiimsan ee wakiilka waa soodhaha iyo chloride polyvinyl (PVC).

soodhaha caustic

Dhamaadkii 2020, awoodda wax-soo-saarka caalamiga ah ee soodhaha caustic waxay gaartay 99.959 milyan oo tan, awoodda wax-soo-saarka soodhaha ee Shiinaha waxay gaartay 44.7 milyan tan, taasoo ka dhigan 44.7% awoodda wax-soo-saarka guud ee adduunka, iyadoo kaalinta koowaad ka gashay wax-soo-saarka adduunka. kartida.

Laga bilaabo 2020, qaybinta awoodda wax-soo-saarka ee suuqa soodhaha ee dalkayga ayaa si tartiib tartiib ah u caddaatay, oo inta badan ku urursan saddex gobol oo Waqooyiga Shiinaha ah, Waqooyi-galbeed Shiinaha iyo Shiinaha Bari.Saddexda gobol ee kor ku xusan awoodda wax-soo-saarka soodhaha waxay ka dhigan tahay in ka badan 80% awoodda wax-soo-saarka guud ee dalka.Waxaa ka mid ah, saamiga hal gobol ee Waqooyiga Shiinaha ayaa sii waday inuu kordho, isagoo gaaray 37.40%.Awoodda wax-soo-saarka soodhaha caustic ee Koonfur-galbeed Shiinaha, Koonfurta Shiinaha iyo Waqooyi-bari Shiinaha waa mid aad u hooseeya, iyo saamiga guud ee awoodda wax-soo-saarka gobol kasta waa 5% ama ka yar.

Waqtigan xaadirka ah, siyaasadaha warshadaha sida dib-u-habaynta saadka-qaranku waxay dejiyeen heerka kobaca awoodda wax-soo-saarka ee warshadaha soodhaha, isla mar ahaantaana, qaabka tartanka ayaa sii waday in la hagaajiyo, iyo xoojinta warshadaha ayaa sii waday kordhiyo.

PVC

PVC, ama polyvinyl chloride, ayaa mar ahaan jirtay caaga guud ee ugu wayn aduunka oo si weyn loo isticmaali jiray.Waqtigan xaadirka ah, waxaa jira laba suuq oo macaamiisha ugu weyn ee PVC ee dalkayga: alaab adag iyo alaab jilicsan.Alaabada adag waxay inta badan yihiin muuqaalo kala duwan, tuubooyin, taargooyin, go'yaal adag iyo alaabta wax lagu qaabeeyo, iwm.;Alaabooyinka jilicsan ayaa inta badan ah filimada, fiilooyinka iyo fiilooyinka, maqaar macmal ah, dhejisyo dhar ah, tuubooyin kala duwan, galoofyada, alaabta carruurtu ku ciyaarto, daboolka sagxadaha ee ujeedooyinka kala duwan, kabaha caaga ah, iyo qaar ka mid ah dahaarka gaarka ah iyo daboolka, iwm.

Marka loo eego baahida loo qabo, sannadihii la soo dhaafay, baahida loo qabo resin PVC ee dalkayga ayaa si joogto ah u kordhay.Sannadka 2019, isticmaalka muuqda ee xabagta PVC ee Shiinaha ayaa gaadhay 20.27 milyan tan, koror sannad-sannadka ah oo ah 7.23%.Codsiyada kala duwan ee resin polyvinyl chloride, waxaa la filayaa in isticmaalka resin polyvinyl chloride ee dalkaygu uu gaaro 22.109 milyan oo tan sanadka 2021, rajada suuqana waa mid aad u badan.

Dulmar guud ee warshadaha Chlor-Alkali

Qaab dhismeedka aasaasiga ah ee silsiladda warshadaha waa in la isticmaalo habka diaphragm ama habka xuubka ionic si electrolyze biyaha milixda ah si loo helo alaabta ceeriin koloriin, iyo isla mar ahaantaana la soo saaro soodhaha caustic, iyo gaaska chlorine waxaa loo isticmaalaa sida alaabta ceeriin ee PVC. wax soo saarka.

Marka laga eego dhinaca wareegga dhaqaalaha, warshadaha chlor-alkali waxaa si weyn u saameeya xaaladda dhaqaale ee sare.Marka dhaqaalaha-macro-dhaqaale uu soo hagaagayo, warshadaha chlor-alkali waxaa dhaqaajiya isticmaalka oo si degdeg ah u koraya;marka dhaqaala-weynuhu hoos u dhaco, baahida loo qabo warshadaha chlor-alkali ayaa hoos u dhacda, in kasta oo saameynta meertadu ay leedahay dib u dhac gaar ah., laakiin isbeddelka warshadaha chlor-alkali asal ahaan waa waafaqsan yahay dhaqaalaha weyn.

Horumarka degdega ah ee dhaqaalaha dalkeeyga iyo baahida xooggan ee suuqa hantida maguurtada ah, "PVC + caustic soda" ee kaalmaynta warshadaha chlor-alkali ee dalkeyga ayaa horumar ballaaran sameeyay, awoodda wax-soo-saarka iyo wax-soo-saarka si degdeg ah u koray.Dalkaygu waxa uu noqday soo saaraha iyo isticmaalka ugu muhiimsan aduunka ee chlor-alkali.
