Ts'ebetsong ea ts'ebetso le ts'ebeliso ea lifilimi tsa polasetiki, ho ntlafatsa thepa ea lihlahisoa tse ling tsa resin kapa filimi tse sa fihlelleng litlhoko tsa theknoloji ea tsona ea ts'ebetso e hlokahalang, ho hlokahala ho eketsa li-additives tsa polasetiki tse ka fetolang litšobotsi tsa tsona tsa 'mele ho fetola ts'ebetso ea sehlahisoa. Jwalo ka e 'ngoe ea li-additives tse hlokahalang bakeng sa filimi e phatlohileng, ka tlase ke kenyelletso e qaqileng ea moemeli oa polasetiki. Ho na le li-agent tse tharo tse sebelisoang hangata tse thibelang ho thibela: oleic amide, erucamide, silicon dioxide; Ntle le li-additives, ho na le li-masterbatches tse sebetsang tse kang li-masterbatches tse bulehileng le li-masterbatches tse boreleli.
1. Moemeli o thellang
Ho eketsa motsoako o boreleli filiming joalo ka ho eketsa lera la metsi pakeng tsa likotoana tse peli tsa khalase, ho etsa hore filimi ea polasetiki e be bonolo ho thellisa lera tse peli empa ho be thata ho li arola.
2. Moemeli oa ho bula molomo
Ho eketsa opener kapa masterbatch filiming jwalo ka ho sebedisa sandpaper ho hohla bokahodimo pakeng tsa dikotwana tse pedi tsa khalase, e le hore ho be bonolo ho arola dikarolo tse pedi tsa filimi, empa ho thata ho thella.
3. Bula sehlopha sa masterbatch
Sebopeho ke silica (inorganic)
4. Sehlopha se setle sa masterbatch
Lisebelisoa: li-amide (tsa tlhaho). Kenya amide le moemeli oa thibelo ho masterbatch ho etsa hore e be 20 ~ 30%.
5. Khetho ea moemeli oa ho bula
Ho masterbatch e bulehileng e boreleli, khetho ea amide le silika e bohlokoa haholo. Boleng ba amide ha bo lekane, e leng se fellang ka tšusumetso ea masterbatch lera nako le nako, joalo ka tatso e kholo, matheba a matšo jj., tseo kaofela li bakoang ke litšila tse feteletseng le litaba tse sa hloekang tsa oli ea liphoofolo. Ts'ebetsong ea khetho, e lokela ho khethoa ho latela teko ea ts'ebetso le ts'ebeliso ea amide. Khetho ea silika e bohlokoa haholo, 'me e lokela ho nahanoa ho tsoa likarolong tse ngata tse kang boholo ba likaroloana, sebaka se itseng sa bokaholimo, litaba tsa metsi, kalafo ea bokaholimo, jj., e nang le tšusumetso ea bohlokoa tlhahisong ea masterbatch le ts'ebetsong ea ho lokolla filimi.
