Choyamba mvetsetsani kuti PVC ndi chiyani.Polyvinyl-Chloride imadziwika kuti PVC.Ndikosavuta kuyambitsa bizinesi yopanga chitoliro cha PVC pang'onopang'ono komanso sing'anga.Mapaipi a PVC amagwiritsidwa ntchito kwambiri m'mafakitale amagetsi, ulimi wothirira ndi zomangamanga.PVC imalowa m'malo mwazinthu zambiri monga nkhuni, mapepala ndi zitsulo pazinthu zambiri.Amagwiritsidwa ntchito kwambiri ngati njira zamagetsi m'nyumba komanso m'mafakitale.
Mapaipi a PVC amagwiritsidwa ntchito kwambiri popereka madzi chifukwa ali ndi mawonekedwe oyenera.Ndizopepuka komanso zotsika mtengo.Mapaipi a PVC ndi osavuta kukhazikitsa ndipo sawononga.Chitoliro cha PVC chili ndi mphamvu zolimba kwambiri zonyamula kuthamanga kwamadzimadzi.Mapaipi a PVC amalimbana kwambiri ndi pafupifupi mankhwala aliwonse ndipo amakhala ndi kutentha kwakukulu komanso mphamvu zotchinjiriza zamagetsi.
Kufunika kwa chitoliro cha PVC kukuchulukirachulukira ku India pomwe zomangamanga zikukula kwambiri.Mapaipi a PVC amagwiritsidwa ntchito kwambiri pantchito yomanga ndi ulimi ndipo kufunikira kukukulirakulira posachedwa.Mapaipi a PVC amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana monga kuthirira madzi, kuthirira kopopera, machubu ozama bwino komanso ngalande zapamtunda.
Mapaipi opindidwa ndi malata amagwiritsidwa ntchito makamaka potulutsa madzi kuchokera kumtunda komwe kumayenera kuthiriridwa madzi.Kufunika kukukulirakulira m'madera akumidzi kwa madzi, ulimi wothirira, kupita patsogolo kwa ntchito yomanga komanso kukulitsa maukonde amagetsi kumidzi.Zoposa 60% za kufunika kwa chitoliro cha PVC kuli mpaka 110 mm m'mimba mwake.
Musanayambe kupanga, muyenera kulembetsa ndi ROC.Kenako pezani Trade Licence kuchokera kwa Municipality.Komanso lembani Laisensi ya Factory malinga ndi malamulo anu aboma.Lemberani kulembetsa kwa Udyog Aadhar MSME pa intaneti ndikulembetsa VAT.Pezani 'No Objection Certificate' kuchokera ku bungwe loyang'anira kuwononga chilengedwe.Pezani chiphaso cha BIS cha Quality Control.Tsegulani akaunti yakubanki yapano mu banki yovomerezeka.Tetezani mtundu wanu ndi Kulembetsa Chizindikiro.Komanso lembani chiphaso cha ISO.
Zida zopangira monga PVC resin, DOP, Stabilizers, Processing acids, Lubricants, Colors ndi Fillers ndizofunikira popanga mapaipi a PVC.Madzi ndi magetsi ndi zofunika.
Pakuti PVC chitoliro kupanga, PVC uncompounded utomoni si oyenera ndondomeko mwachindunji.Kuti mukhale osalala komanso okhazikika, zowonjezera zimafunika kusakanikirana ndi utomoni wa PVC.Pali zowonjezera zomwe zimagwiritsidwa ntchito popanga mapaipi a PVC ndi awa: DOP, DIOP, DBP, DOA, DEP.
Plasticizers - pali mapulasitiki omwe amagwiritsidwa ntchito ndi DOP, DIOP, DOA, DEP, Reoplast, Paraplex etc.
Mafuta - Buty-Stearate, Glycerol Moni-Stearate, Epoxidised Monoester ya oleic acid, stearic acid etc.
Ndondomeko isanayambe PVC, utomoni umaphatikizidwa ndi plasticizers, stabilizers, lubricant ndi fillers kupititsa patsogolo ndondomeko ndi bata la mankhwala.Zosakaniza izi ndi utomoni zimasakanizidwa ndi chosakaniza chothamanga kwambiri.
Utoto umadyetsedwa pawiri screw extruder ndipo kufa ndi zoyikapo zimayikidwa m'mimba mwake momwe zimafunikira.Kenako mankhwala a PVC amadutsa m'chipinda chotenthetsera ndikusungunula pansi pa psinjika ndi kutentha kwa mbiya.Kuyika chizindikiro kumachitika panthawi ya extrusion.
Mipope imachokera ku extruder utakhazikika mu ntchito sizing.Pali mitundu iwiri ya kukula yomwe imagwiritsidwa ntchito monga Pressure Sizing ndi Vacuum Sizing.
Pambuyo sizing pali traction.The chubu traction unit chofunika mosalekeza haulage mapaipi kukhala extruder ndi extruder.
Kudula ndi njira yomaliza.Pali mitundu iwiri ya njira zodulira zomwe zimagwiritsidwa ntchito mapaipi a PVC.Pamanja ndi Automatic.Pamapeto pake mapaipi amayesedwa zizindikiro za ISI ndikukonzekera kutumiza.
Ku India mitundu yambiri ya PVC Pipe Manufacturing Machine amapangidwa koma pakati pa Devikrupa Gulu Lopanga Makina Abwino Kwambiri.
