Xogta hantida maguurtada ah ayaa si xun loo xakameynayaa, PVC-ga waa la iftiimiyay.

Isniintii, xogta hantida maguurtada ah ayaa sii waday inay noqoto mid caajis ah, taas oo saameyn xun ku yeelatay rajada baahida. Sida ugu dhow, qandaraaska ugu weyn ee PVC wuxuu ku dhacay in ka badan 2%. Toddobaadkii hore, xogta CPI ee Maraykanka bishii Luulyo ayaa ka hoosaysay sidii la filayay, taas oo kordhisay rabitaanka khatarta ah ee maalgashadayaasha. Isla mar ahaantaana, baahida dahabka, sagaal qalin iyo tobanka xilli ee ugu sarreeya ayaa la filayaa inay soo hagaagto, taas oo bixisay taageerada qiimaha. Si kastaba ha ahaatee, suuqu wuxuu leeyahay shaki ku saabsan xasiloonida soo kabashada ee dhinaca baahida. Korodhka ay keentay dib u soo kabashada baahida gudaha ee dhexdhexaadka iyo mustaqbalka fog ayaa laga yaabaa in aanay awoodin in ay ka saarto kororka ka soo kabashada saadka iyo hoos u dhaca baahida ay keentay baahida dibadda ee cadaadiska hoos u dhaca. Later, waxay u horseedi kartaa dib u soo kabashada qiimaha badeecadaha, iyo rajada sicir-bararka ee kor u kaca mar kale, uma badna in Fed ee rajada kor u kaca dulsaarka dulsaarka uu hoos u dhaco, kaas oo sidoo kale cadaadis saaraya qiimaha diskka.

Asal ahaan, rajada laga qabo suuqa PVC-ga ayaa dabacsan, laakiin ma jiraan meelo badan oo dhalaalaya oo mudan in la xuso muddada gaaban. Toddobaadkan, dhismaha PVC wuxuu bilaabay inuu hoos u dhaco wax yar, iyo dayactirka ugu sarreeya ayaa soo maray. Marxaladda hore, sababaha dayactirka xilliyeed awgeed, aaladaha baarkinka ayaa dib u bilaabay wax soo saarka midba midka kale, waxaana la filayaa in dhinaca sahaydu ay soo kabsato. Si kastaba ha ahaatee, habka kalsiyum carbide ee shirkadu khasaaraha faa'iidada badeecada, bilawga dhismaha waa la xakameynayaa, dhinaca baahida ayaa ka badan. Marka la eego filashooyinka suuqa, sababtuna tahay saamaynta dhawaanta ee xilli-ka-baxsan gudaha iyo xakamaynta faafitaanka iyo daciifinta baahida dibadda ee cadaadiska hoos u dhaca, hawlgallada hoose ayaa aad uga taxaddar badan, ilaalinaya laxanka buuxinta kaliya ee loo baahan yahay. taasoo keentay dib u soo kabashada alaabada bulsheed ee gudaha, taas oo jiidanaysa qiimaha. , Inkasta oo qiimaha diskku uu hoos u dhacay qiimaha macdanta dibadda ee calcium carbide V ee macdanta, aasaaska si tartiib tartiib ah u dabciyo margin way adagtahay in la horumariyo dib-u-celinta joogtada ah ee diskka, laakiin waxaa mahad leh kharashka yar ee taageeraya qiimaha hoose. Hoos u dhaca muddada gaaban ayaa sidoo kale xaddidan.

Guud ahaan, arrimaha bullish-ka ah ee ku riixay qiimaha si ay u sii wadaan dib u soo kabashada marxaladda hore ayaa wiiqay booska hadda jira. Ka dib wareeggii ugu dambeeyay ee dib u soo celinta qiimaha, hoos u dhaca xogta hantida maguurtada ah ayaa cadaadis badan saartay qiimaha. Maaddaama xilliga gaaban ee dahabka gudaha, sagaal, qalin, iyo tobanka xilliga isticmaalka ugu sarreeya uu soo dhowaanayo, waxaa jira rajo ah horumarinta baahida. Isbeddelka baahida muddada gaaban waxay noqon doontaa diiradda isbeddelka qiimaha dhow. U fiirso hagaajinta baahida. Waxaa la filayaa in qiimaha muddada gaaban uu sii wadi doono isbeddelka.
