Okokuqala qonda ukuba yintoni iPVC.I-Polyvinyl-Chloride yaziwa ngokuba yiPVC.Kulula ukuqalisa ishishini lokwenziwa kwemibhobho yePVC kwizikali ezincinci neziphakathi.Imibhobho yePVC isetyenziswa kakhulu kumashishini ombane, okunkcenkceshela kunye nokwakha.I-PVC ithatha indawo yezixhobo ezininzi ezinje ngomthi, iphepha kunye nentsimbi kwizicelo ezininzi.Isetyenziswa ngokubanzi njengemibhobho yombane ekhaya nakwimizi-mveliso.
Imibhobho yePVC isetyenziswa ngokubanzi kunikezelo lwamanzi njengoko ineempawu ezifanelekileyo kuyo.Ikhaphukhaphu kwaye ineendleko eziphantsi.Imibhobho yePVC kulula ukuyifakela kwaye ayidleki.Umbhobho we-PVC unamandla aphezulu okunyamezela ukuthwala uxinzelelo oluphezulu lwe-fluid.Imibhobho yePVC ixhathisa kakhulu phantse kuzo zonke iikhemikhali kwaye inobushushu obuninzi kunye neempawu zokugquma umbane.
Imfuno yombhobho wePVC iyanda eIndiya njengoko iziseko zophuhliso zikhula phezulu.Imibhobho yePVC isetyenziswa ngokubanzi kwicandelo lolwakhiwo kunye nezolimo kwaye imfuno iyanda kwikamva elikufutshane.Imibhobho yePVC isetyenziswa ngokubanzi ngeenjongo ezahlukeneyo ezifana nonikezelo lwamanzi, ukunkcenkceshela ngesitshizi, izikimu zequla elinzulu kunye nokukhupha amanzi emhlabeni.
Imibhobho ebotyiweyo kunye nethanki isetyenziswa ikakhulu ukukhupha amanzi ukusuka emhlabeni apho ukugcwala kwamanzi kuyimfuneko.Imfuno iyanda kwiindawo zasemaphandleni kunikezelo lwamanzi, ukunkcenkceshela, kunye nenkqubela phambili kushishino lokwakha kunye nokwandiswa kothungelwano lombane kwimimandla yasemaphandleni.Ngaphezulu kwe-60% yemfuno yombhobho wePVC ifikelela kwi-110 mm ngaphandle kwedayamitha.
Ngaphambi kokuvelisa kuqala, kufuneka ubhalise kwi-ROC.Emva koko ufumane iLayisensi yoRhwebo kuMasipala.Faka isicelo seLayisensi yoMzi-mveliso ngokwemigaqo yelizwe lakho.Faka isicelo sobhaliso lwe-Udyog Aadhar MSME kwi-intanethi kunye nobhaliso lwe-VAT.Fumana 'Isiqinisekiso Sokuchasa' kwibhodi yolawulo longcoliseko karhulumente.Fumana isatifikethi se-BIS soLawulo loMgangatho.Vula i-akhawunti yebhanki yangoku kwibhanki yelizwe.Khusela ibhrendi yakho ngoBhaliso loPhawu.Kwaye ufake isicelo sesatifikethi se-ISO.
Izinto eziluhlaza ezifana ne-PVC resin, i-DOP, i-Stabilizers, i-Processing acids, i-Lubricants, iMibala kunye neziFilisi ziyafuneka kwimveliso yepayipi ye-PVC.Amanzi nombane zibalulekile.
Ukwenziwa kombhobho wePVC, i-PVC engaxutywanga nentlaka ayifanelekanga inkqubo ethe ngqo.Inkqubo egudileyo kunye nokuzinza, izongezo ziyafuneka ukuba zixutywe ne-PVC resin.Kukho ezinye izongezo ezisetyenziselwa ukwenza imibhobho yePVC zezi: DOP, DIOP, DBP, DOA, DEP.
IiPlastiki - kukho iplastiizer eqhelekileyo esetyenziswayo yi-DOP, DIOP, DOA, DEP, Reoplast, Paraplex njl.
Izithambisi – iButy-Stearate, iGlycerol Moni-Stearate, i-Epoxidised Monoester ye oleic acid, stearic acid njl.
Ngaphambi kokuba inkqubo iqale i-PVC, i-resin idibaniswe ne-plasticizers, i-stabilizers, i-lubricant kunye ne-fillers ukuphucula inkqubo kunye nokuzinza kwemveliso.Ezi zithako kunye ne-resin zixutywe kunye nomxube wesantya esiphezulu.
I-resin iyondliwa kwi-screw extruder ephindwe kabini kwaye ifa kunye nokufakwa kufakwe kwi-diameter efunekayo.Okulandelayo iikhompawundi ze-PVC zigqithiswa kwigumbi elifudumeleyo kwaye zinyibilike phantsi koxinzelelo lwe-screw kunye nobushushu bombhobho.Ukumakishwa kwenziwa ngexesha le-extrusion.
Imibhobho ivela kwi-extruder epholileyo ekusebenzeni kokulinganisa.Kukho ubukhulu becala iindidi ezimbini zokulinganisa ezisetyenziswayo ezizezi, ubungakanani boxinzelelo kunye nobungakanani beVacuum.
Emva kokulinganisa kukho ukutsala.Iyunithi yokutsalwa kwetyhubhu iyadingeka ukuze kuthuthwe ngokuqhubekayo imibhobho ekhutshwa yi-extruder.
Ukusika yinkqubo yokugqibela.Kukho iintlobo ezimbini zeendlela zokusika ezisetyenziselwa imibhobho yePVC.Incwadi kunye ne-Automatic.Ekugqibeleni imibhobho ivavanywa kumanqaku e-ISI kwaye ilungele ukuthunyelwa.
EIndiya iintlobo ezininzi zoomatshini bokwenza umbhobho wePVC zenziwa kodwa phakathi kwale Devikrupa Iqela lenza oomatshini abaBalaseleyo.
