Ngakhale ma pulasitiki ali ndi zinthu zambiri zabwino, osati mtundu uliwonse wa mapulasitiki omwe angakhale ndi zinthu zabwino zonse. Mapangidwe apakunja azachuma ndi opanga mafakitale ayenera kumvetsetsa zomwe zimapangitsa kuti zikhale za pulasitiki zosiyanasiyana kuti apange zopangidwa bwino pulasitiki. Katundu wa pulasitiki, amatha kugawidwa kukhala malo oyambira akuthupi, makina ochitira makina, katundu wamafuta, katundu wamagetsi, zojambula zamagetsi zimatanthauza kuti mafakitale kapena zida zipolopolo. Ndiwopika kwambiri ndi mphamvu yabwino kwambiri, kukana kwamphamvu, kukana kutentha, kuuma ndi ukalamba. Mafakitale aku Japan adzatanthauzira kuti "itha kugwiritsidwa ntchito ngati zigawo zamagetsi komanso makina oteteza kwambiri kuposa 100 ℃, makamaka amagwiritsidwa ntchito m'makampani".
Pansipa tidzatchulanso zomwe anthu ambiri amakondaZida Zoyesa:
1.Mellet yoyenda(MFI):
Ntchito zoyesa kusungunuka mtengo wa MFR yamtengo wapatali ya pulasitiki yosiyanasiyana ndikuyimitsa maluwa. Ndioyenera kwa mapulasi a usikono monga polycarbonate, polyyarylfone, masamba anzeru, ntchentche, naneloni ndi wopitilira kutentha kwambiri. Ndizoyeneranso polyethylene (pe), polystyrene (PS), Polyplellene (PP), Polyarfoldehyde (pomsbacbonate (PC) Kukwaniritsa miyezo: Iso 1133, Astm D1238, GB / T3682
Njira yoyesera ndikulola kuti ma pulasitiki asungunuke mu pulasitiki mkati mwa nthawi inayake (mphindi 10), pansi pa kutentha kwina (g). Mtengo wokulirapo, wabwinoko wokonzetsa udzi wa pulasitiki, ndi mosemphanitsa. Muyezo wogwiritsa ntchito kwambiri ndi Astme d 1238. Chida choyezera cha muyezo ichi chikusungunuka. Ntchito yoyesererayo ndi iyi: The Polymer (pulasitiki (pulasitiki (pulasitiki) kuyesedwa kuti iziyesedwe mu povu yaying'ono, ndipo kumapeto kwa poyambira kumalumikizidwa ndi chubu chowonda, m'mimba mwake ndi 2.095mm, ndi kutalika kwa chubu ndi 8mm. Pambuyo pakuthamanga mpaka kutentha kwinakwake, kumapeto kwa zinthu zophatikizika kumazizidwa pansi pochita pisitoni, ndipo kulemera kwa zinthu zopangira kumayesedwa paphiri 10, zomwe ndi cholowera cha pulasitiki. Nthawi zina mudzaona kuyimira Mi25g / 10min, zomwe zikutanthauza kuti 25 magalamu apulasitiki athetsedwa mu mphindi 10. Mtengo wa mika womwe umagwiritsidwa ntchito wamba uli pakati pa 1 ndi 25. Zokulirapo mumitsempha ya pulasitiki yophika ndi yocheperako; Kupanda kutero, kukulira kwa pulasitiki ndi kukulira kwa maselo.

Makina oyesera akunja (Makina A Tnsile): Kuyesa, kuwononga, kugwedezeka ndi mphamvu zina zamapulasitiki.
Itha kugawidwa m'magulu otsatirawa:
1)Kulimba kwamakokedwe&Mlengalenga:
Kukhala wamphamvu, komwe kumadziwikanso kuti mphamvu ya anthu, amatanthauza kukula kwa mphamvu yomwe ikufunika kuti itambasule kwambiri pamlingo wina, ndipo kutalika kwa kutalika kwake ndi mtunda. Kukula kwamphamvu kuthamanga kwa fanizoli nthawi zambiri ndi 5.0 ~ 6.5mm / mphindi. Njira yoyeserera mwatsatanetsatane malinga ndi anyezi D638.
2)Mphamvu yosinthika&Kuwerama mphamvu:
Kugwedeza Mphamvu, komwenso kumadziwika kuti ndi mphamvu yotherax, kumagwiritsidwa ntchito pofuna kudziwa kukana kwa ma pulasitiki. Itha kuyesedwa molingana ndi njira ya Asther790 ndipo nthawi zambiri imafotokozedwa molingana ndi mphamvu zambiri. General Plastics ku PVC, Melamine urin, epoxy utoto ndi polyester akugwa mphamvu ndizabwino kwambiri. Fiberglass imagwiritsidwanso ntchito kukonza kusakaniza kwa pulasitiki. Kugwada kwambiri kumatanthauza kupsinjika kwa cholumikizira chomwe chimapangidwa mu gawo la kuwonongeka kwa elastic nthawi yomwe fanizoli imakhala yovuta (njira yoyeserera ngati mphamvu). Mwambiri, kugwada chachikulu kugwa, kumalibwinowo kwa pulasitiki.
3)Mphamvu Zovuta:
Mphamvu yopumira imatengera kuthekera kwa ma pulasitiki kuti tithane ndi mphamvu yakunja. Mtengo woyeserera ukhoza kutsimikizika molingana ndi njira ya AstMD695. Polyacetal, polyester, acrylic, urethral amasumidwa ndi Meramin alen ali ndi zinthu zabwino kwambiri pankhaniyi.
