Saudi Arabia Imposes Anti-Dumping Lub Luag Haujlwm Ntawm Sulfated Naphthalene Formaldehyde (SNF) ntshuam los ntawm Tuam Tshoj thiab Russia

Tsis ntev los no, Saudi Arabia tau tshaj tawm qhov kev txiav txim siab zaum kawg ntawm kev tawm tsam ntawm 18.12% mus rau 34% ntawm cov khoom lag luam sulfated naphthalene formaldehyde (SNF) los ntawm lossis xa tawm los ntawm Tuam Tshoj thiab Russia.

Saudi Arabia tau hais tias pib txij lub Kaum Ob Hlis 3, 2024, nws yuav ua rau lub luag haujlwm tiv thaiv kev pov tseg zaum kawg ntawm 18.12% mus rau 34% ntawm cov khoom lag luam sulfated naphthalene formaldehyde (SNF) (Concrete Improvers Sulfated Naphthalene Formaldehyde) los ntawm Suav teb thiab Russia. . Saudi tus lej se rau cov khoom yog 382440 thiab 290410, thiab lub luag haujlwm yuav siv tau rau tsib xyoos.

Saudi Arabia tau qhia tias qhov kev txiav txim siab tau ua raws li "International Trade Relief Law," txhawm rau tiv thaiv kev lag luam hauv tsev los ntawm kev puas tsuaj los ntawm kev ua lag luam tsis ncaj ncees. Vim lub siab loj heev cov khoom uas tsis tshua muaj nqi no tau muab tso rau hauv cov chaw tsim khoom hauv Saudi Arabia, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm kev tsim kho kev lag luam sai sai, tsoomfwv Saudi ntseeg tias tsis muaj kev cuam tshuam, qhov chaw muaj sia nyob rau cov lag luam hauv tsev yuav txuas ntxiv zuj zus. Lub luag hauj lwm los tiv thaiv dumping yog npaj los tsa tus nqi ntawm cov khoom tuaj txawv teb chaws, yog li ua kom muaj kev lag luam ntau dua thiab cov txiaj ntsig zoo dua rau cov neeg tsim khoom hauv zos.

Kev lag luam loj rau sulfated naphthalene formaldehyde (SNF) tau maj mam nthuav dav, tshwj xeeb tshaj yog nyob rau hauv Middle East, nrog kev loj hlob muaj zog ntawm kev thov los ntawm kev tsim kho kev lag luam hauv cov teb chaws xws li Saudi Arabia thiab UAE.

Sulfated naphthalene formaldehyde (SNF) yog ib qho kev ua haujlwm siab ua kom dej-txo tus neeg sawv cev. Nws muaj qhov zoo xws li kev txo qis dej ntau, tsis muaj kev thim rov qab, tsis muaj cua nkag, thiab muaj zog yoog raws, uas tuaj yeem txhim kho kev ua haujlwm ntawm pob zeb, txo cov dej sib tov, thiab txhim kho lub zog ntawm cov pob zeb. SNF tuaj yeem siv dav hauv kev lag luam, kev tsim kho pej xeem, kev txuas hniav, chaw nres nkoj, roj av, thiab kev txuag dej. Raws li cov dej-txo cov neeg ua haujlwm tuaj yeem txhim kho cov khoom siv ntawm cov pob zeb, txhim kho kev ua haujlwm, thiab txo cov peev txheej, lawv tau dhau los ua ib qho tseem ceeb ntawm cov cement pob zeb, feem ntau hu ua cov khoom thib tsib ntawm cov cement pob zeb. Kev tshawb fawb txog cov dej-txo cov neeg ua hauj lwm hauv Suav teb tau pib lig, nrog rau thawj qhov kev taw qhia ntawm cov khoom siv hauv cov cement pob zeb tsim nyob rau xyoo 1940s. Ntau hom dej-txo cov neeg ua haujlwm qhia qhov sib txawv ntawm cov dej txo qis, thiab lawv cov khoom hauv pob zeb kuj sib txawv. Cov tshuaj txo cov dej zoo ib yam muaj cov dej txo qis thiab ua haujlwm tsis zoo; naphthalene-raws li dej-txo cov neeg sawv cev yog siv nyob rau hauv tej qhov chaw tab sis muaj tej yam toxicity thiab ib puag ncig muaj kuab paug. Polycarboxylate-based high-performance water-reduced agents yog copolymer khoom ntawm carboxylated multicomponent copolymer thiab lwm yam zoo additives. Lawv cov qauv molecular cov yam ntxwv ua rau polycarboxylate-raws li dej-txo cov neeg ua haujlwm tau hloov mus rau ntau yam khoom siv raw thiab ib puag ncig. Nyob rau hauv Suav teb, cov khoom tseem ceeb ntawm cov dej-txo cov neeg sawv cev yog thib ob-tiam naphthalene-raws li cov khoom thiab thib peb-tiam polycarboxylate-based khoom. Txawm li cas los xij, nyob rau hauv xyoo tas los no, kev txhim kho thiab kev siv ntawm polycarboxylate-raws li kev ua haujlwm siab dej-txo cov neeg ua haujlwm tau nce sai heev. Polycarboxylate-raws li dej-txo cov neeg ua haujlwm tam sim no tau siv dav hauv cov haujlwm tseem ceeb thiab cov haujlwm tseem ceeb hauv yuav luag txhua lub tebchaws, tshwj xeeb hauv kev txuag dej, kev siv hluav taws xob, hydraulic, marine engineering, thiab choj tej yaam num.

Middle Eastern manufacturers, raws li kev lag luam thiab kev tsim kho vaj tse hauv cheeb tsam txuas ntxiv mus, tau pom cov tuam txhab hauv zos tsis tu ncua. Cov tuam txhab no paub txog kev lag luam hauv zos thiab cov neeg siv khoom xav tau, muaj peev xwm muab cov khoom lag luam thiab cov kev pab cuam ntau dua, thiab muaj qee yam zoo hauv kev tswj cov nqi. Yog li ntawd, lawv maj mam tuav ib feem ntawm kev lag luam nruab nrab mus rau qis-kawg thiab nthuav mus rau hauv kev lag luam high-end. Piv txwv li, Chemanol, ib tug ntawm cov loj SNF cov neeg tsim khoom, tau tsim nyob rau hauv Jubail Industrial City-1, Saudi Arabia, nyob rau hauv 1989. Nyob rau hauv 2008, Chemanol tau teev nyob rau hauv lub Saudi Tshuag txauv (Tadawul). Lub tuam txhab tag nrho cov peev txheej yog ze li ntawm 1 lab tons hauv ib xyoos, thiab nws cov khoom lag luam suav nrog formaldehyde, cov dej ua kom muaj txiaj ntsig zoo, cov amino resins, hexamethylenetetramine, polyformaldehyde, dimethylformamide, methylamine, pentaerythritol, thiab sodium formate, ua rau formaldehyde loj tshaj plaws. tsim tawm hauv thaj av Gulf.
