Ukuhlaziywa kweqhaza labakhuthele abahlanganisiwe ekukhiqizweni kwamapayipi e-PVC kanye nokufakelwa | Umhlahlandlela wokusebenziseka kahle kwamafomula we-PVC angenisa imvelo

Ngohlelo lokusebenza olusakazekile lwamapayipi e-PVC kanye nokufakwa emikhakheni yokwakha amanzi kanye nokudonsa, ubunjiniyela bakamasipala kanye nokunisela kwezolimo, ukumelana kwabo nezimo zokulwa nokuguga sekuyizidingo eziyinhloko zomkhakha. Njengesigaba esiyisisekelo sezithasiselo zePVC zokucubungula, abaqinisi abahlanganisiwe banquma ngokuqondile ukusebenza kahle kokukhiqiza kanye nokusebenza kwamapayipi kwamapayipi kanye nokufakwa kokulungisa okushisayo nokwenza okufunayo. Le ndatshana ihlaziya ngokujulile izilinganiso zesayensi nezinhlelo zokusebenza zezimboni ze-calcium zinc zigcina kanye namafomula angenamsebenzi anemvelo, futhi ahlinzeka ngezinkomba zobuchwepheshe ezibalulekile zabakhiqizi be-PVC.

1. Imisebenzi emine eyisisekelo yabakhuthazayo abahlanganisiwe: ephelele ephelele ekukhiqizweni kwesicelo

• Abaqiniswa phezulu kakhulu kwe-Thermal: Ukuvimba ukusabela kwe-chain kokuwohloka kwe-PVC

I-PVC Resin ithambekele ekuphuziseni nasekulinganiseni ngenxa yokukhishwa kwe-HCL ngesikhathi sokuqhuma okusheshayo okusheshayo (160-200 ℃). Abaqinisi bezinhlanganisela abahlanganisiwe behlisa izinto ze-acidic ngokusebenzisa umphumela we-synergistic we-metal insipho yensimbi (njenge-calcium zinc ukuqina) kanye ne-epoxy organics) kanye ne-pvc engokwesimo, bese uqinisekisa ukuqeda kwamapayipi.

• I-Lubrant Balance: Yehlisa i-torque kanye nokusetshenziswa kwamandla

Ngokusebenzisa isilinganiso esiqondile sokuthambisa kwangaphakathi (njengo-Stearc Acid Alcohol) kanye nokuthambisa kwangaphandle (njenge-polyethylene wax), i-vispethylene wax), i-viscosity ye-PVC incibilika, futhi i-expentenness annowracting ye-UPVC Amapayipi athuthukile athuthukiswa.

• I-anti-oxidation kanye nokuqiniswa kwesimo sezulu: Nweba impilo yamapayipi angaphandle

Ukungeza ama-ultraviolet atholakalayo (njenge-titanium dioxide) futhi ama-antioxidants kakhulu athuthukisa ukusebenza okulwa nokuguga kwamapayipi ama-pvc drainage ngaphansi kokuvezwa kwemvula, ukubhekana nezidingo zamazinga we-ASTM D1784.

• Ukulandela imvelo: Hlangana nezidingo zomhlaba wonke

Abaqiniswa abahola ama-Holy-Free Composite (njengochungechunge lwe-calcium zinc) badlulise isitifiketi se-rohs kanye namazinga wamanzi we-NSF, futhi alungele izidingo zokukhiqizwa kwamapayipi wePVC.

2. Umhlahlandlela kwingxenye yabaqinisi I-PVC PIPE FOMULA PLANE OPPTIATIONS PLANE
Kususelwa kumodeli ye-PVC Resin (enjenge-SG-5, SG-8), kunconywa ubuchwepheshe bokucubungula (ukukhishwa kwesimo sokuhlanganisa) kanye nezimo zesicelo esibulalayo, kunconywa izixazululo zesayensi:

• Amapayipi e-General PVC: 1.8% -2.5% stabilizer (kususelwa ku-100% resin)
• Amapayipi aphezulu amelana nesimo sezulu esiphikisayo sezulu
• Ifomula engenamsebenzi enobungane bemvelo: I-calcium zinc stabilizer 2.8% -3.5% + ama-auxiliary stabilizer (njenge-hydrotalcite)
• Ukukhishwa okuphezulu okunejubane elincanyana: 3.0% -3.5% i-stabilizer ephezulu yokugcoba ukunciphisa ubungozi bokuncipha kokuncipha
