Mocheso o phahame o phahame, o qhalana haholo, sekhahla sa sekhukhu se phahameng, haholo-holo polasetiki e nang le kristasta e phahameng. Kabo ea mocheso le ntho e sa thabiseng ea polasetiki ea polasetiki e ama ho shrinkage le tataiso.
Ho Tšoarelo le Nako le nako li boetse li ama khahlano. Khatello e phahameng, nako e telele e tla putlama empa tataiso e kholo. Ka hona, ha mocheso o boima, khatello ea ho phuthoa ka lebelo le ho fafatsa ka ente le lintlha tse ling hape li ka loketseng ho fetola shrinkage ea likarolo tsa polasetiki.
Boqapi bo bokhutšoanyane ba shrinkage ea shrinkage ho latela mefuta e mengata ea polasetiki, sebopeho, ho latela shrinkage ea karolo ea polasetiki, ebe ho bala boholo ba kokoana-hloko.
Bakeng sa likarolo tsa polasetiki tse phahameng haholo 'me ho thata ho utloisisa sekhahla sa shrinkage, hangata ho loketse ho sebelisa mekhoa e latelang ho etsa hlobo:
a) nka hore ho shōleloa sekhukhuni tse nyane tsa likarolo tsa polasetiki ka bophara le shrumage e kholo ho ba le sebaka sa ho fetola tlhahlobo kamora tlhahlobo ea bol.
b) Teko ea Mold ho fumana foromo ea sistimi ea ho lahla, boholo le maemo a ho etsa.
c) Phetoho ea boholo ba likarolo tsa polasetiki e tla nkuoa ka mor'a ho phethoa (tekanyo e lokela ho ba lihora tse 24 kamora ho hlobola).
d) Fetola mold ho latela shrinkage ea 'nete.
E) Liphoofolo li ka lula le boleng ba shrinkage li ka fetoloa hanyane ka ho fetola maemo a ts'ebetso ka nepo ho fihlela litlhoko tsa likarolo tsa polasetiki.
Ea bobeli,Moqomo
- Ho ferekana ha li-wormoplators hangata ho hlahlojoa ke letoto la li-index tse kang boima ba li-profinse, li-achifikes bolelele ba lipalesa tsa bongaka le litefo Bakeng sa lipolasetsi tsa lebitso le ts'oanang, litlhaloso li tlameha ho hlahlojoa ho tseba hore na koae ea bona e loketse bobui ba ente.
Ho latela litlhoko tsa boqapi ba boqapi, phofo ea polasetiki e tloaelehileng e ka aroloa ka mekhahlelo e meraro:
a) Ho pharalla hantle oa PA, Pe, PS, PP, CA le PolymethylthyRitinoene;

a) mocheso. Mocheso o boima oa lintho tse bonahalang o tla eketsa metsi, empa lipesaleme tse fapaneng le tsona li hanyetsa, PS (haholo-holo li hanyetsa le boleng ba MFR Bakeng sa pe, pom, ebe ke eketseha ka mocheso le ho fokotseha ho ba le tšusumetso e nyane ho mela ea bona.
b) khatello. Khatello ea Boima e Thisang Boikemisetso e eketseha ka ts'ebetso, haholo pe, pom e tebile, ka hona nako ea ente e hlabang khatello ea taolo ea ho laola phallo.
c) sebopeho sa die. Sebopeho se phehang sebopeho sa sistimi, boholo, tsamaiso ea khatelo le lintlha tse ling ho ama phallo ea phetetso e hlakisang ka kotloloho ka har'a semola.
Moralo oa hlobo o lokela ho ipapisa le tšebeliso ea polasetiki, khetha mohanyetsi o nepahetseng.Mol le mabaka a mang a ente le mabaka a eketsehileng a ka fetola ho khotsofatsa ho fihlela litlhoko tsa botsoi.
