PVC (PolyVinyl Chloride) mavharuvhu ebhora anoshandiswa zvakanyanya epurasitiki akavhara mavharuvhu.Ivhavha ine bhora rinotenderedzwa rine bore.Nekutenderedza bhora chikamu chekota, bhora riri mukati kana kuti perpendicular kune piping uye kuyerera kunovhurwa kana kuvharika.Mavharuvhu ePVC akasimba uye anodhura.Uyezve, anogona kushandiswa kune dzakasiyana siyana midhiya, kusanganisira mvura, mweya, makemikari anoparadza, asidhi uye mabhesi.Kuenzaniswa nendarira kana Stainless simbi bhora mavharuvhu, iwo akatemerwa tembiricha yakaderera uye kumanikidzwa uye ane yakaderera mechanical simba.Iwo anowanikwa neakasiyana ekubatanidza pombi, senge sockets (glue connection) kana tambo dzepombi.Kaviri mubatanidzwa, kana mavharuvhu echokwadi emubatanidzwa, ane pombi yakaparadzana magumo ekubatanidza anonamirwa kumutumbi wevharuvhu netambo ine tambo.Iyo valve inogona kubviswa nyore nyore kuti itsive, kuongororwa uye kuchenesa.
Kugadzirwa kwePolyVinyl Chloride
PVC inomirira PolyVinyl Chloride uye ndiyo yechitatu inonyanya kushandiswa polymer yekugadzira mushure mePE nePP.Inogadzirwa nekuita kwe57% chlorine gasi uye 43% ethylene gasi.Chlorine gasi inotorwa ne electrolysis yemvura yegungwa, uye ethylene gasi inowanikwa ne distillation yemafuta asina kuchena.Mukuenzanisa nemamwe mapurasitiki, kugadzirwa kwePVC kunoda zvakanyanya kushoma mafuta asina kuchena (PE nePP inoda kutenderedza 97% ethylene gasi).Chlorine uye ethylene inobata uye inoita ethanedichlorine.Izvi zvinogadziriswa kuti zvibudise Vinylchlorine monomer.Ichi chinyorwa chine polymerized kuita PVC.Pakupedzisira, zvimwe zvinowedzera zvinoshandiswa kushandura zvinhu zvakadai sekuoma uye elasticity.Nekuda kwemaitiro akareruka ekugadzira uye kuwanikwa kukuru kwezvakagadzirwa, PVC inodhura-inoshanda uye inogoneka zvinhu zvichienzaniswa nemamwe mapurasitiki.PVC ine simba rinopikisa chiedza chezuva, makemikari uye oxidation kubva mumvura.
PVC zvivakwa
Rondedzero iri pazasi inopa mhedziso yeakakosha maitiro echinyorwa:
- Hupenyu huremu, hwakasimba uye hwakareba
- Inokodzera kudzokorodza uye yakaderera kukanganisa kwezvakatipoteredza kana ichienzaniswa nemamwe mapurasitiki
- Kazhinji inoshandiswa pakushandisa hutsanana, semvura yekunwa.PVC chinhu chakakosha chinoshandiswa kuchengeta kana kutamisa zvigadzirwa zvekudya.
- Inopesana nemakemikari akawanda, acids uye mabhesi
- Mazhinji ePVC bhora mavharuvhu anosvika kuDN50 ane yakanyanya kudzvanywa mwero wePN16 (16 bar pakudziya kwekamuri).
PVC ine yakaderera kupfava uye kunyungudika.Naizvozvo, hazvikurudzirwe kushandisa PVC kune tembiricha iri pamusoro pe60 degrees Celsius (140°F).
Applications
PVC mavharuvhu anoshandiswa zvakanyanya mukutarisira mvura nekudiridza.PVC yakakodzerawo kune zvinoparadza midhiya, semvura yegungwa.Uyezve, zvinhu zvacho zvinopokana neakawanda acids uye mabhesi, munyu mhinduro uye organic solvents.Mukushandisa uko makemikari anoparadza uye maasidhi anoshandiswa, PVC saka inowanzosarudzwa pamusoro pesimbi isina tsvina.PVC inewo zvimwe zvayakaipira.Chinonyanya kukosha ndechekuti PVC yakajairwa haigone kushandiswa kune tembiricha inodarika 60°C (140°F).PVC haidziviriri kune anonhuwirira uye chlorinated hydrocarbons.PVC ine yakaderera mechanicha simba pane ndarira kana Stainless simbi, uye saka PVC mavharuvhu kazhinji yakaderera kumanikidzwa rating (PN16 yakajairika mavharuvhu kusvika DN50).Rondedzero yemisika yakajairika iyo PVC mavharuvhu anoshandiswa:
- Zvekudiridzira zvemumba / Nyanzvi
- Kurapa kwemvura
- Mamiriro emvura nematsime
- Aquariums
- Mapombi
- Madziva ekutuhwina
- Chemical processing
- Kugadziriswa kwezvokudya
