Ukuthunyelwa kwePVC yaseTshayina eIndiya
eTshayinaPVC ukuthumela ngaphandleukuya eIndiya,
Ngo-2021, i-PVC yaseTshayina yathumela ngaphandle ifikelele kwimbali ye-1.7538 yezigidi zeetoni, iphezulu kakhulu kune-1.0889 yezigidi zeetoni ngo-2016.Umthumeli wePVC ngaphandle, eUnited States, iye yafumana iforce majeure yokunciphisa imveliso, neyona inkulu ehlabathiniUmvelisi wePVC, iTshayina, ingenise elona xesha libalaseleyo lokuthumela ngaphandle.Idityaniswe nokubandayo koMnyhadala weNtwasahlobo ngo-2021, umsantsa we-EXPORT wase-United States wasuka kwikota yesine ka-2020 ukuya kwikota yesithathu ka-2021.
Njengomrhwebi omkhulu wehlabathi – iIndiya, minyaka leukungeniswa kwePVCifuna ngaphezu kwe-1.5 yezigidi zeetoni, kwaye kwiminyaka yakutshanje, uphuhliso olukhawulezayo lwezoqoqosho lwaseIndiya, imfuno yokungenisa elizweni iyanda.Ukuchatshazelwa yi-force majeure yase-United States kunye nokunciphisa ukuthunyelwa kwamanye amazwe, Ithuba lokuba i-China ithumele ngaphandlePVC ukuya eIndiyaivula.Ukusukela ngoMatshi ukuya ku-Epreli ka-2021, abathengi baseIndiya banexhala lokunqongophala kobonelelo lwehlabathi kunye nokunyuka kwexabiso, ngoko ke inani elikhulu leemveliso zePVC zingeniswa ngaphandle, njengoko kunokubonwa kulo mfanekiso ulandelayo.Nangona kunjalo, ngo-2022, ixabiso leemveliso zaseTshayina lisezantsi kwexabiso lehlabathi, kwaye umsebenzi wokulwa nokulahla kwi-PVC evela e-China iphela ngoFebruwari.Ngenzuzo yexabiso, iPVC yaseTshayina ithatha ngokukhawuleza imarike yaseIndiya.
Kukho umda omkhulu wentsebenziswano phakathi kweTshayina, eyona mveliso inkulu ehlabathini, kunye neIndiya, elona lizwe lingenisa impahla ngaphandle elizweni;Ngaphandle korhwebo lwangaphambili oluchasene nokulahlwa, i-PVC yase-China yathumela ngaphandle ijikile ukusuka kwi-advanteji yomsantsa wobonelelo lwehlabathi ukuya kwindibaniselwano yenzuzo yamaxabiso ehlabathi.Kwelinye icala, imarike yasekhaya yaseChina ikwimfuno engxamisekileyo yokuthumela ngaphandle ukuze kuthomalaliswe uxinzelelo lonikezelo lwangaphakathi kwixesha elifutshane.Kwelinye icala, amanye amashishini ajika ingqalelo yawo ekuthengisweni kwePVC phesheya ukuze aphucule eyawo inkqubo yorhwebo.
ukungeniswa kwePVC, PVC ukuthumela ngaphandle, Umthumeli wePVC ngaphandle, PVC ongenisa ngaphandle, Umvelisi wePVC, PVC ukuya eIndiya,
IPVC sisishunqulelo sepolyvinyl chloride.I-resin yinto ehlala isetyenziselwa ukuveliswa kweeplastiki kunye neerubha.I-PVC resin ngumgubo omhlophe osetyenziswa ngokuqhelekileyo ukuvelisa i-thermoplastics.Yimathiriyeli eyenziweyo esetyenziswa kakhulu ehlabathini namhlanje.I-Polyvinyl chloride resin ineempawu ezibalaseleyo ezifana nezixhobo ezininzi eziluhlaza, iteknoloji yokuvelisa ekhulile, ixabiso eliphantsi, kunye noluhlu olubanzi lokusetyenziswa.Kulula ukusetyenzwa kwaye inokucutshungulwa ngokubumba, i-laminating, isitofu sokubumba, i-extrusion, i-calendering, i-blow folding kunye nezinye iindlela.Ngeempawu ezintle zomzimba kunye neekhemikhali, isetyenziswa kakhulu kushishino, ulwakhiwo, ezolimo, ubomi bemihla ngemihla, ukupakishwa, umbane, izinto eziluncedo zikawonke-wonke, kunye namanye amacandelo.Iireyini zePVC zinokumelana neekhemikhali eziphakamileyo.Yomelele kakhulu kwaye iyamelana namanzi kunye ne-abrasion.I-Polyvinyl chloride resin (PVC) inokucutshungulwa kwiimveliso ezahlukeneyo zeplastiki.I-PVC yiplastiki ekhaphukhaphu, engabizi kakhulu, kwaye inobuhlobo nokusingqongileyo.I-Pvc Resin inokusetyenziswa kwimibhobho, iifreyimu zefestile, i-hoses, izikhumba, iintambo zocingo, izihlangu kunye nezinye iinjongo eziqhelekileyo iimveliso ezithambileyo, iiprofayili, izixhobo, iipaneli, i-injection, ukubumba, iimbadada, ityhubhu enzima kunye nezinto zokuhombisa, iibhotile, amaphepha, ikhalenda, inaliti eqinileyo kunye nokubumba, njl njl kunye namanye amacandelo.
Iimbonakalo
I-PVC yenye yezona zinto zisetyenziswa kakhulu kwi-thermoplastic resins.Ingasetyenziselwa ukwenza iimveliso ezinobunzima obuphezulu kunye namandla, njengemibhobho kunye nokufakelwa, iingcango zeprofayili, iifestile kunye namaphepha okupakisha.Isenokwenza iimveliso ezithambileyo, ezinje ngeefilim, amashiti, iingcingo zombane kunye neentambo, iibhodi eziphantsi kunye nesikhumba sokwenziwa, ngokongezwa kweeplasticizers.
