I-resin ye-PVC yombhobho wokunkcenkceshela
PVC resin yombhobho wokunkcenkceshela,
umbhobho wokunkcenkceshela izinto ekrwada, pvc yombhobho wokunkcenkceshela,
Umbhobho wokunkcenkceshela wePVC:
(1) Umbhobho wokunkcenkceshela we-PVC unokumelana ne-asidi ebalaseleyo, ukuxhathisa kwealkali kunye nokumelana nomhlwa, ofaneleke kakhulu kwishishini lemichiza.Umphezulu wodonga lombhobho wokunkcenkceshela wePVC ugudile.Ukuxhatshazwa kwamanzi kuncinci, kwaye i-coefficient yayo yobunzima yi-0.009 kuphela, ephantsi kuneminye imibhobho.Ngaphantsi komlinganiselo ofanayo wokuhamba, ububanzi bombhobho bunokuncitshiswa.Ukumelana noxinzelelo lwamanzi, ukuxhathisa uxinzelelo lwangaphandle kunye nokuchasana kwefuthe lemibhobho yokunkcenkceshela ye-PVC iphezulu kakhulu, efanelekileyo kubunjineli bombhobho phantsi kweemeko ezahlukeneyo.Ixabiso eliphantsi kwaye lisetyenziswa ngokubanzi.
(2) Umbhobho wokunkcenkceshela wePVC unokulandela kakuhle inkqubo yokukhula kwezityalo ukuze kuphunyezwe unkcenkceshelo lwangoku.Ukusetyenziswa kwamanzi okunkcenkceshela kunokukhethwa ngokomlinganiselo othile wokufuma kwezityalo kunye nomhlaba.
(3) Umbhobho wokunkcenkceshela PVC yeyona nto ngokupheleleyo inokusekelwe kwiimpawu kweat yangoku ukufikelela unikezelo lwamanzi oluchanekileyo kunye nesichumiso kwingcambu yeendlela zokunkcenkceshela izityalo.Oku kunokunciphisa umsebenzi wezandla.
(4) Umbhobho wokunkcenkceshela we-PVC unokuthutha ukusetyenziswa kwamanzi okunkcenkceshela okufanelekileyo ngokweemfuno zokukhula kwezityalo, ezinokuthi ziqinisekise ukunkcenkceshela kwangexesha nangendlela efanelekileyo kwezityalo kwaye ubeke isiseko esiluqilima sokuphucula isivuno sezityalo.
(5) Imibhobho yokunkcenkceshela isetyenziswa ngokubanzi kubonelelo lwamanzi ezidolophini nasemaphandleni angaphakathi nangaphandle, ukuphuculwa kwamanzi ezilalini, ukunkcenkceshela kwimihlaba yeefama, imibhobho yokuhambisa amanzi anetyuwa kunye nemveliso yeekhemikhali, ukuhanjiswa kwamanzi kushishino lwasemanzini, umoya wokuphefumla emigodini, unikezelo lwamanzi kunye ne drainage, isitshizi sokulungisa umhlaba. ukunkcenkceshela kunye nezinye iiprojekthi ezinkulu nezincinci.
I-Polyvinyl Chloride (i-PVC) yi-resin ye-thermoplastic ehambelanayo eyenziwa yi-polymerization ye-vinyl chloride monomer.Ngenxa yomahluko wemathiriyeli ekrwada, kukho iindlela ezimbini zokwenza i-vinyl chloride monomer calcium carbide inkqubo kunye nenkqubo yepetroleum.I-Sinopec PVC ithatha inkqubo yokunqunyanyiswa kabini, ngokulandelelana kwiNkampani yeMichiza yeShin-Etsu kunye neNkampani ye-Oxy Vinyls yaseMelika.Imveliso inokumelana nokugqwala kweekhemikhali, ipropathi egqwesileyo yokugquma umbane kunye nokuzinza okuhle kweekhemikhali.Ngomxholo ophezulu we-chlorine, izinto eziphathekayo zinokutshatyalaliswa komlilo okulungileyo kunye neempawu zokuzicima.I-PVC kulula ukuyiqhuba nge-extrusion, isitofu sokubumba, i-calendering, ukubunjwa kokuvuthela, ukuxinzelela, ukubumba kunye nokubumba kwe-thermal, njl.
