Uhlalutyo lwendima yokuziqhelanisa nokuziqhelanisa nokuveliswa kwemibhobho ye-PVC kunye ne-Fittings | ISIKHOKELO SOKUGQIBELA

Ngokusetyenziswa okubanzi kwemibhobho ye-PVC kunye nokusebenza kwimihlaba yokwakha amanzi kunye nokuntywila, ubuchwephesha boomasipala kunye nokungavisisini kwezolimo, ukungavisisani kwezolimo, kuya kuba ziimfuno ze-Anti-Ukwaluphala. Njengoko udidi oluphambili lwe-PVC ongezelelweyo, ukuzinza kwezinto ezihlanganisiweyo ngokuthe ngqo kuchonga ukusebenza kakuhle kwemveliso kunye nokusebenza kwendlela yokusebenza kwemibhobho kunye nokufakwa kwemibhobho yokuphuculwa komoya wokuzimela kunye nokuphuculwa kwenkohliso. Eli nqaku lihlaziya ngokunzulu ubume benzululwazi kunye nokusetyenziswa kwemveliso ye-calcium stabilizers kunye neefomula ezinokukhokela ngokusingqongileyo, kwaye zibonelela ngeembekiselo zobuchule be-PVC.

I-1. Imisebenzi emine ephambili yezitayile: I-escort epheleleyo kwimveliso ukuya kusetyenziso

• Ukusebenza nzima kwe-thermal ye-thermal: Ukuthintela i-Chain Reance ye-PVC Deogradition

I-PVC resin ixhonywe ekutyhelini kunye nokukhululwa ngenxa yokukhutshwa kwe-HCL ngexesha lokuqhubekeka kwesantya esiphezulu (160-200 ℃). Ukulungelelanisa izilwanyana ze-thermal ze-thermal azichaze izinto ze-acidic ze-synergistististic sthsgistic zentsimbi (ezinje nge-calcium stabilizers) kunye nezinto ze-eposcy, zandise i-PVC yokuphelisa imibhobho.

• Ibhalansi yoLungisi: ukunciphisa ukusetyenziswa kwe-torque kunye namandla

Ngomyinge ocacileyo we-ofisi yangaphakathi (enjengotywala be-Acid) kunye ne-volythylene yax), ukulungiswa kwe-PVC kuyathintelwa, kwaye ukulungiswa kwe-PVC kuyathintelwa kunye nenaliti yokuchama kwemibhobho ye-ivc kuphucuka.

• I-Anti-Oxidation kunye neMozulu yeMozulu: Yandisa ubomi bemibhobho yangaphandle

Ukongeza i-Abyraviolet Absthers (njengeTitanium Dioxide) kunye ne-antioxididaides iphucula ukwenziwa kwemibhobho ye-PVC ye-PVC yeMigangatho ye-ASTM D1784.

• Ukuthotyelwa kwendalo: hlanganisa iimfuno zolawulo lwehlabathi

Izizwe ezikhokelayo zingenazinzo zimahla (ezinjenge-calcium zinc uthotho) zidlulise isiqinisekiso se-rohs kunye ne-NSF yokusela amanzi, kwaye zilungele iimfuno zemveliso ye-PVC yeBanga le-PVC yeBanga le-PVC.

2. Isikhokelo kumlinganiso wenani lezinto ezihlanganisiweyo zongezwa | Isicwangciso sokuphucula umbhobho we-PVC
Ngokusekwe kwimodeli ye-PVC

• Imibhobho yePVC ngokubanzi: 1.8% -2.5% ye-stabilizer (esekwe kwi-100% i-resin)
• Imibhobho yemozulu ephezulu yemozulu ye-IVV
• IFomula eNcwadiyo engenasiseko i-Calcium Stabilizer 2.8% -3.5% + Stailict Stabilizer (njenge-hydrotalcite)
• Isantya esiphezulu se-pumele esine-pumele esinesondlo: 3.0% -3.5% ephezulu ye-Lightity Staiblity yokunciphisa umngcipheko wokunyibilikisa
