Umgomo wokusebenza komlawuli we-PVC foaming ufezwa kakhulu ngokulawula izakhiwo zomzimba nezamakhemikhali zokuncibilika kwe-PVC. Imisebenzi ethile yile elandelayo:
1. Khuthaza ukwenziwa kwepulasitiki kanye nokufana kokuncibilikisa
Uchungechunge olude lwama-molecule lokulawula i-foaming (ACR) lusheshisa ukwenziwa kwepulasitiki kwezinto ngokugoqa uchungechunge lwama-molecule e-PVC, lunciphisa izinga lokushisa lokucubungula, futhi lwakha isakhiwo senethiwekhi yejeli. Le nqubo ayisheshisi nje kuphela isivinini sokuncibilika, kodwa futhi ikhuthaza ukuhlakazeka okufanayo kwezithasiselo kanye nama-ejenti e-foaming, kunciphisa amaphutha angaphakathi ekuncibilikeni.
2. Thuthukisa amandla nokunwebeka kokuncibilika
Isakhiwo senethiwekhi esinezinhlangothi ezintathu esakhiwe ukuboshwa kwamaketanga ama-molecule sithuthukisa kakhulu amandla okuncibilika, okwenza sikwazi ukuhlanganisa igesi ngempumelelo futhi simelane nokuhlangana kwamaseli ngesikhathi senqubo yokugqwala. Ngesikhathi esifanayo, sinikeza ukuncibilika amandla, okuvumela ama-pores ukuthi akhule futhi anciphe ngokulinganayo, okugcina isakhiwo seseli esivaliwe.
3. Ukulawula ibhalansi ye-viscoelasticity yokuncibilika
Umlawuli ulungisa i-viscoelasticity yokuncibilika kwe-PVC, wandise isikhathi sokuncibilika kwegwebu, futhi ufanise izinga lokubola kwe-ejenti yokuncibilika nezinga lokusabalala kwegesi. Lo mthetho unganciphisa izinga lokuqhekeka kwegwebu (njengoba kuboniswe kudatha yokuhlola, izinga lokuqhekeka lehle kusuka ku-25% kuya ku-8%) futhi lenze ngcono ukufana kokusatshalaliswa kwegesi ekuncibilikeni.
4. Lungiselela isakhiwo sembobo kanye nokuqina
Amandla okuncibilika athuthukisiwe kanye nokuqina kungavimbela ukuqhekeka kokuphuma kwama-pores aseduze, kwakha isakhiwo seseli esincane nesifanayo esivaliwe. Ama-regulator anesisindo esiphezulu sama-molecule, njenge-HL530, anganciphisa kakhulu ubuningi bomkhiqizo, ngenkathi elawula ukugeleza kochungechunge lwama-molecule ukuvimbela ukuwa kwama-pores okubangelwa ukuphumula ngokweqile.
5. Thuthukisa ubuso kanye nezakhiwo zemishini zomkhiqizo
Ukuthuthukiswa kokufana kokuncibilika kunciphisa izimpawu zokugeleza kobuso kanye nokukhubazeka kokuncibilika, futhi kuthuthukisa ukuhlanzeka kobuso. Ukwanda kwamandla okuncibilika ngokungaqondile kuthuthukisa ukumelana nokushayisana kanye nokuqina kobukhulu bomkhiqizo.
Ngamafuphi, isimiso sayo sokusebenza ngokuyinhloko siwukufinyelela ukulawula okunembile kwamandla okuncibilika, i-viscoelasticity, kanye ne-foaming kinetics ngokusebenzisa imiphumela yokugoqa ngokomzimba kanye ne-chemical synergistic, ngaleyo ndlela kulinganiswa ubuningi bamaseli, ubuqotho besakhiwo, kanye nokusebenza kahle kokucubungula.
