PVC macompounds akavakirwa pakubatanidzwa kwePVC polymer RESIN uye zvinowedzera zvinopa kuumbwa kunodiwa kwekupedzisira-kushandiswa (Mapombi kana Rigid Profiles kana Flexible Profiles kana Sheets).Mushonga unoumbwa nekunyatsosanganisa pamwe chete zvigadzirwa, izvo zvinozoshandurwa kuita "gelled" chinyorwa pasi pesimba rekupisa uye simba rekugera.Zvichienderana nemhando yePVC uye zvinowedzera, chidimbu chisati chaiswa gelation chinogona kunge chiri poda yakasununguka (inozivikanwa semusanganiswa wakaoma) kana mvura iri muchimiro chekuisa kana mhinduro.
Mishonga yePVC kana yagadzirwa, uchishandisa mapurasitiki, kuita zvinhu zvinochinjika, zvinowanzonzi PVC-P.
PVC Compounds kana yakagadzirwa isina plasticizer yezvakaoma zvikumbiro inosarudzwa PVC-U.
PVC Compounding inogona kupfupikiswa sezvinotevera:
Iyo yakaoma PVC yakaoma musanganiswa poda (inonzi Resin), iyo zvakare ine zvimwe zvinhu zvakaita sezvitsigiso, zvekuwedzera, mafirita, zvinosimbisa, uye zvinodzoreredza moto, zvinofanirwa kuve zvakasanganiswa zvakanyanya mumichina yekusanganisa.Iko kusanganisa uye kugovera kusanganisa kwakakosha, uye zvese mukuteerana neyakatsanangurwa tembiricha miganho.
Zvinoenderana nekugadzirwa, iyo PVC resin, plasticizer, Filler, stabilizer uye zvimwe zvinobatsira zvinoiswa mukupisa musanganiswa.Mushure me6-10 maminetsi buritsa mune inotonhora musanganisi (6-10 mins) ye premixing.PVC musanganiswa unofanirwa kushandisa inotonhora musanganisi kudzivirira zvinhu kunamatira pamwechete mushure memusanganisi unopisa.
Musanganiswa wezvinhu mushure mekugadzirwa kwepurasitiki, kusanganisa uye kuparadzira zvakaenzana paanenge 155 ° C-165 ° C inobva yadyiswa kune Cold musanganiswa.Iko kunyunguduka kwePVC kusanganiswa kunozopetwa.Mushure mekuputika, tembiricha yegranules inogona kudzikiswa kusvika 35°C-40°C.Zvino mushure memhepo-yakatonhodzwa yevibrating sieve, tembiricha inodonha pazasi tembiricha yekamuri kuti itumire kune yekupedzisira chigadzirwa silo yekurongedza.
