Melemo ea ho sebelisa lithuso tsa ho sebetsa tsa ACR:
1. E na le tumellano e ntle le resin ea PVC, e bonolo ho qhalakanya ka resin ea PVC, 'me e bonolo ho e sebetsa.
2. E na le polasetiki ea ka hare 'me e ka sebelisoa ka thepa ea lieta, lisebelisoa tsa terata le lisebelisoa tsa cable, le lisebelisoa tse bonolo tse hlakileng ho fokotsa palo ea polasetiki e sebelisoang le ho rarolla bothata ba ho falla ha holim'a li-plasticizers.
3. E ka ntlafatsa haholo ho feto-fetoha ha mocheso o tlase le matla a tšusumetso ea sehlahisoa.
4. Ho ntlafatsa haholo ho benya ha holim'a sehlahisoa, ho feta ACR.
5. Botsitso bo botle ba mocheso le ho hanyetsa boemo ba leholimo.
6. Fokotsa viscosity ea ho qhibiliha, khutsufatsa nako ea polasetiki, 'me u eketse chai ea yuniti.Ntlafatsa matla a ts'usumetso le ho feto-fetoha ha mocheso o tlase oa sehlahisoa.
Ho nkela ACR sebaka ka bongata bo lekanang ho ka fokotsa ts'ebeliso ea mafura kapa ho eketsa ts'ebeliso ea li-filler ha u ntse u boloka thepa ea thepa, ho bula mekhoa e mecha ea ho ntlafatsa boleng ba sehlahisoa le ho fokotsa litšenyehelo.
