Okokuqala qonda ukuthi iyini i-PVC.I-Polyvinyl-Chloride yaziwa ngokuthi i-PVC.Kulula ukuqalisa ibhizinisi lokukhiqiza amapayipi e-PVC ngezinga elincane neliphakathi.Amapayipi e-PVC asetshenziswa kakhulu ezimbonini zikagesi, zokunisela nezokwakha.I-PVC ithatha indawo yezinto eziningi ezifana nokhuni, iphepha nensimbi emisebenzini eminingi.Isetshenziswa kabanzi njengamapayipi kagesi ezindlini kanye nasekusetshenzisweni kwezimboni.
Amapayipi e-PVC asetshenziswa kabanzi ekunikezeni amanzi njengoba enesici esifanele kuwo.Ilula futhi inezindleko eziphansi.Amapayipi e-PVC kulula ukuwafaka futhi awaboli.Ipayipi le-PVC linamandla aphezulu okubamba ukuthwala ukucindezela koketshezi oluphezulu.Amapayipi e-PVC amelana kakhulu cishe nawo wonke amakhemikhali futhi anokushisa okuphezulu kanye nezindawo zokuvala ugesi.
Isidingo sepayipi le-PVC siyanda eNdiya njengoba ingqalasizinda ikhula phezulu.Amapayipi e-PVC asetshenziswa kabanzi emkhakheni wezokwakha kanye nezolimo futhi isidingo siyenyuka esikhathini esizayo esiseduze.Amapayipi e-PVC asetshenziswa kabanzi ngezinhloso ezehlukene njengokuphakelwa kwamanzi, ukuchelela ngesifutho, izikimu zemithombo yamashubhu ajulile kanye nokukhipha amanzi emhlabathini.
Amapayipi avalekile nakathayela asetshenziswa kakhulu ukudonsa amanzi emhlabeni lapho kudingeka khona ukugcwala kwamanzi.Isidingo siyakhula ezindaweni zasemakhaya sokuphakelwa kwamanzi, ukuchelela, nentuthuko embonini yezokwakha kanye nokwandiswa kwenethiwekhi kagesi ezindaweni zasemakhaya.Ngaphezu kuka-60% wesidingo samapayipi e-PVC afinyelela ku-110 mm ububanzi bangaphandle.
Ngaphambi kokukhiqiza kuqala, kufanele ubhalise ne-ROC.Bese uthola Ilayisensi Yokuhweba kuMasipala.Faka futhi isicelo seLayisense Yemboni ngokwemithetho yezwe lakho.Faka isicelo sokubhaliswa kwe-inthanethi kwe-Udyog Aadhar MSME kanye nokubhaliswa kwe-VAT.Thola 'Isitifiketi Sokungaphikisani' ebhodini lokulawula ukungcoliswa kombuso.Thola isitifiketi se-BIS Sokulawulwa Kwekhwalithi.Vula i-akhawunti yasebhange yamanje ebhange elikazwelonke.Vikela umkhiqizo wakho ngokubhaliswa kophawu lwentengiso.Futhi ufake isicelo sesitifiketi se-ISO.
Izinto ezingavuthiwe ezifana ne-PVC resin, DOP, Stabilizers, Processing acids, Lubricants, Colors and Fillers ziyadingeka ekwenzeni amapayipi e-PVC.Amanzi nogesi kubalulekile.
Ngokukhiqizwa kwamapayipi e-PVC, i-PVC engahlanganisiwe ayifanele inqubo eqondile.Ukuze kube nenqubo ebushelelezi nokuzinza, izithasiselo ziyadingeka ukuze kuhlanganiswe ne-PVC resin.Kukhona ezinye izithasiselo ezisetshenziselwa ukukhiqiza amapayipi e-PVC yilezi: DOP, DIOP, DBP, DOA, DEP.
Ama-Plasticizer - kukhona i-plasticizer evamile esetshenziswayo i-DOP, i-DIOP, i-DOA, i-DEP, i-Reoplast, i-Paraplex njll.
Izithambisi - Buty-Stearate, Glycerol Moni-Stearate, Epoxidised Monoester of oleic acid, stearic acid njll.
Ngaphambi kokuthi inqubo iqale i-PVC, i-resin ihlanganiswa nama-plasticizers, ama-stabilizers, ama-lubricant nama-fillers ukuthuthukisa inqubo nokuzinza komkhiqizo.Lezi zithako kanye ne-resin kuhlanganiswe ne-mixer enesivinini esikhulu.
I-resin ifakwa ku-double screw extruder futhi i-die kanye nezinto ezifakiwe zifakelwe ububanzi obudingekayo.Okulandelayo izinhlanganisela ze-PVC zidluliselwa ekamelweni elishisayo futhi zincibilike ngaphansi kokucindezelwa kwesikulufu nokushisa komgqomo.Ukumakwa kwenziwa ngesikhathi sokukhishwa.
Amapayipi avela ku-extruder epholile ekusebenzeni kokulinganisa.Zimbili izinhlobo zokulinganisa ezisetshenziswayo okuyi-Pressure Sizing kanye ne-Vacuum Sizing.
Ngemuva kokulinganisa kukhona i-traction.Iyunithi yokudonsa kweshubhu iyadingeka ukuze kuthuthwe amapayipi akhishwa i-extruder.
Ukusika kuyinqubo yokugcina.Kunezinhlobo ezimbili zamasu okusika asetshenziselwa amapayipi e-PVC.Imanuwali ne-Othomathikhi.Ekugcineni amapayipi ahlolelwa amamaki e-ISI futhi alungele ukuthunyelwa.
E-India izinhlobo eziningi zoMshini Wokukhiqiza Ipayipi le-PVC ziyenziwa kodwa phakathi kwalokhu Imishini Engcono Kakhulu Yeqembu Le-Devikrupa Lenza.
