Izinto eziluncedo kwimibhobho yamanzi yePVC:
⑴ Inokuqina okulungileyo kunye namandla acinezelayo.
⑵ Ukumelana nolwelo olusezantsi:Udonga lwe-UPVCimibhobho igudile kakhulu kwaye inokumelana kancinci nolwelo. I-coefficient yayo erhabaxa yi-0.009 kuphela. Ukongeza, umthamo wothumelo lwamanzi unokunyuswa nge-20% xa kuthelekiswa nemibhobho yentsimbi enobubanzi obufanayo kunye ne-40% xa kuthelekiswa nemibhobho ekhonkrithi.
⑶ Ukumelana nokugqwesa kwe-corrosion kunye nokuxhathisa imichiza: Imibhobho ye-UPVC ine-asidi egqwesileyo kunye nokuxhathisa kwe-alkali kunye nokumelana nokubola. Abachatshazelwa ngumswakama kunye nomhlaba we-PH, ngoko ke akukho nyango lokulwa ne-corrosion olufunekayo xa ubeka imibhobho.
⑷ Ukuqina kwamanzi afanelekileyo: Ukufakwa kwemibhobho ye-UPVC inokuqina kwamanzi okulungileyo kungakhathaliseki ukuba idibaniswe ngamakhonkco okanye amakhonkco erubha.
⑸ I-Anti-bite: Kuba imibhobho ye-UPVC ingengomthombo wesondlo, ayisayi kukhukuliseka ziimpuku.
Iindawo zesicelo
Imibhobho yePVC yeplastikizisetyenziswa ikakhulu kwiinkqubo zonikezelo lwamanzi kwindawo yokuhlala, iinkqubo zonikezelo lwamanzi kulwakhiwo lwasezidolophini, iinkqubo zemibhobho yezityalo zamanzi kunye neenkqubo zonikezelo lwamanzi ezolimo. Imibhobho yeplastiki yePVC ingasetyenziswa njengemibhobho yokuhambisa amandla kwiingcingo kunye neetyhubhu zokufakela zonyango. Ukongeza, imibhobho yeplastiki yePVC isenokusetyenziswa ngaphantsi komhlaba njengamazibuko okutsalwa kwerhasi kwiindawo zemigodi yamalahle, njengamazibuko okungenisa umoya angaphantsi komhlaba, kunye nokufakwa kwemibhobho kwimigodi yamalahle engaphantsi komhlaba. Uluhlu lwesicelo lwayo lubanzi kakhulu.
Imibhobho emincinci yePVC yeplastiki isetyenziswa ikakhulu njengemibhobho yamanzi yasekhaya, ephakathi ingasetyenziswa njengemibhobho yamanzi aphantsi komhlaba asezidolophini, kwaye leyo inobukhulu obukhulu ingasetyenziswa njengemibhobho yamanzi kwiProjekthi yokuNyusa aManzi okuMazantsi ukuya kuMntla. Kukwakho nombhobho wePVC omncinci wePVC onokusetyenziswa njengombhobho wokuhambisa amandla.
Ukuba umbhobho wePVC oveliswe ngokukhawuleza ujika tyheli, kufuneka ujonge ingxaki yezixhobo zokuvelisa umbhobho wePVC.
1. Ukuba kukho ingxaki nge-thermocouple okanye i-fan, iya kubangela ukuba umgqomo ugqithise kwindawo kwaye ubangele ukuba umkhiqizo ube phuzi, oko kukuthi, ukutshisa kunye nokujika. Isisombululo: Jonga ukuba ii-thermocouples kwindawo nganye yomgqomo zisebenza ngokufanelekileyo kwaye ngaba abalandeli kwindawo nganye basebenza ngokwesiqhelo.
2. Ukuba i-oyile yesiphaluka ivaliwe, ukushisa kwe-friction ye-screw ayikwazi ukukhutshwa ngokufanelekileyo, okuya kubangela ukuba i-screw idlule kwaye ibangele ukuba izinto zidibanise kwaye zijike ziphuzi. Isisombululo: Khangela ukuba i-oyile yokuhambisa ubushushu ye-screw yanele, ingaba ipompo yeoli isebenza ngokufanelekileyo, kwaye ingaba umbhobho weoyile uvaliwe.
3. Kwimeko yokugqoka i-screw enzima, i-gap phakathi kwe-screw kunye ne-barrel iba nkulu, kwaye ukukwazi kwe-screw ukutyhala izinto kuba kubi kakhulu, okuya kubangela ukuba izinto zibuyele kwi-barrel, ukwenzela ukuba izinto ziya kutshisa. ixesha elide ngaphakathi emgqomeni, okukhokelela ekubeni tyheli. Isisombululo: Ungajonga kwaye ulungelelanise isithuba se-screw okanye ubuyisele isikrufu.
