Imibhobho ye-PVC ithatha imibhobho ye-PVC-U yokukhupha amanzi, eyenziwe nge-polyvinyl chloride resin njengeyona nto iphambili ekrwada.Zongezwa kunye nezongezo eziyimfuneko kwaye zenziwe ngokucutshungulwa kwe-extrusion.Ingumbhobho wokuhambisa amanzi okwakhiwa ngamandla amakhulu, ukuzinza okulungileyo, ubomi benkonzo ende kunye nokusebenza kweendleko eziphezulu.Ingasetyenziswa kwisakhiwo sombhobho, inkqubo yepayipi yogutyulo kunye nenkqubo yombhobho wokungenisa umoya.
Iingenelo zombhobho wePVC zezi zilandelayo:
1. Ine-tensile elungileyo kunye namandla oxinzelelo kunye nokhuseleko oluphezulu.
2. Ukuxhathisa ulwelo oluncinane:
Udonga lombhobho wePVC lugudile kakhulu kwaye ukuchasana nolwelo kuncinci kakhulu.I-coefficient yayo erhabaxa yi-0.009 kuphela.Umthamo wayo wokuhambisa amanzi unokunyuswa ngama-20% xa kuthelekiswa nombhobho wentsimbi we-diameter efanayo kunye ne-40% ephezulu kunombhobho wekhonkrithi.
3. Ukumelana nokugqwesa okugqwesileyo kunye nokumelana neekhemikhali:
Imibhobho ye-PVC inokumelana ne-asidi ebalaseleyo, ukuxhathisa kwe-alkali, ukuxhathisa ukubola.Abachatshazelwa kukufuma kunye nomhlaba PH.Akukho nyango lwe-anticorrosive olufunekayo ekubekweni kwemibhobho.Umbhobho unokumelana ne-corrosion egqwesileyo kwi-asidi ye-inorganic, iialkali kunye neetyuwa.Ifanelekile ukukhutshwa kwamanzi amashishini kunye nokuthutha.
4. Uxinzelelo lwamanzi olulungileyo: Ufakelo lwemibhobho ye-PVC inobuxhakaxhaka obuhle bamanzi kungakhathaliseki ukuba ibhondi okanye i-rubber ring ring.
5. I-Anti-bite: Umbhobho wePVC awuyena umthombo wesondlo, ngoko awuyi kutshatyalaliswa ngamagundane.Ngokovavanyo olwenziwe yiNational Health Foundation eMichigan, iimpuku azikwazi nokuluma imibhobho yePVC.
6. Ukumelana nokuguga okulungileyo: Ubomi benkonzo eqhelekileyo bunokufikelela ngaphezu kwe-50.
iminyaka.
Isizathu sokusebenzisa imibhobho ye-PVC ayisiyonto nje izibonelelo zokusebenza ezingentla.Ubunzima bayo obulula bunokugcina iindleko zokuthutha koomatshini obunzima kwaye unciphise kakhulu ixesha lokubhoboza imingxuma kwimibhobho.Nokuba kwiinyikima okanye kwezinye iimeko, imibhobho yePVC inokubakho ingagungqi.Oku kwenza umbhobho wePVC ngakumbi nangakumbi nabaxhasi.
