Lintlha tsa bohlokoa tsa taolo ea ts'ebetso bakeng sa regulator ea PVC foaming

PVC e foaming regulator e ka re thusa ho tlisa thepa e ntle nakong ea tlhahiso le ts'ebetso ea PVC, e nolofalletsang maikutlo a rona ho tsoela pele hantle le ho hlahisa lihlahisoa tseo re li batlang. Leha ho le joalo, re boetse re hloka ho ela hloko lintlha tse 'maloa tsa bohlokoa tsa taolo ea indasteri ha re e hlahisa, e le hore maikutlo a rona a ka tsoela pele hantle.

Polasetiki e entsoeng ka lekoeba ea PVC e foaming regulator e arotsoe ka mekhoa e meraro: sebopeho sa bubble core, katoloso ea bubble core, le ho tiisa 'mele oa foam. Bakeng sa maqephe a foam a PVC a nang le lik'hemik'hale tse ekelitsoeng tsa foaming, katoloso ea li-bubble nuclei e na le phello e matla boleng ba letlapa la foam. PVC ke ea limolek'hule tsa ketane tse otlolohileng tse nang le liketane tse khutšoane tsa limolek'hule le matla a tlase a qhibilihang. Nakong ea ts'ebetso ea ho atolosoa ha motheo oa bubble ho li-bubble, ho qhibiliha ha hoa lekana ho koahela li-bubble, 'me khase e na le tšekamelo ea ho khaphatseha le ho kopana ho li-bubble tse kholo, ho fokotsa boleng ba sehlahisoa sa maqephe a foam.

Ntho ea bohlokoa ea ho ntlafatsa boleng ba PVC foaming modifiers ke ho matlafatsa matla a ho qhibiliha a PVC. Ho tsoa tlhahlobong ea litšobotsi tsa ts'ebetso ea lisebelisoa tsa polymer, ho na le mekhoa e fapaneng ea ho ntlafatsa matla a ho qhibiliha a PVC, empa tsela e molemohali ke ho eketsa li-additives tse matlafatsang matla a ho qhibiliha le ho fokotsa mocheso oa ho sebetsa. PVC ke ea thepa ea amorphous, 'me matla a eona a ho qhibiliha a fokotseha ka mocheso o ntseng o eketseha oa ho qhibiliha. Ka lehlakoreng le leng, matla a eona a ho qhibiliha a eketseha ka mocheso o fokotsehang oa ho qhibiliha, empa phello ea ho pholisa e lekanyelitsoe mme e sebetsa feela e le mosebetsi o thusang. Lisebelisoa tsa ts'ebetso ea ACR kaofela li na le phello ea ho ntlafatsa matla a ho qhibiliha, a eketsehang ka keketseho ea litaba tse laolang tse fokang. Ka kakaretso, ha feela screw e na le bokhoni bo lekaneng ba ho qhalakanya le ho kopanya, ho eketsa li-modifiers tse phahameng tsa viscosity ho na le phello e kholo ho ntlafatsa matla a ho qhibiliha.

Ka holimo ke kenyelletso e khuts'oane ea lintlha tsa bohlokoa tsa taolo ea ts'ebetso ea foam bakeng sa li-modifiers tsa foam tsa PVC. Ha re li hlahisa, re lokela ho ela hloko sebopeho, ho atolosoa le ho folisa li-nuclei tsa bona tsa bubble le ho li laola ka thata.
