SMC insulation board vagadziri vanotaura nezve hunhu hwemidziyo yekuisa

①Mapurasitiki mazhinji akareruka muhuremu, akagadzikana mumakemikari, uye haaite ngura;

②Good impact resistance;

③Ine kujeka kwakanaka uye kupfeka kuramba;

④Kuvharira kwakanaka uye kuderera kwekushisa conductivity;

⑤Kuumbika, kunaka kwemavara, mutengo wakaderera wekugadzirisa;

⑥Mapurasitiki mazhinji ane kushomeka kwekupisa, kuwedzera kwekuwedzera kwemafuta uye nyore kupisa;

⑦ Kusagadzikana kwedimensional uye nyore deformation;

⑧Mazhinji mapurasitiki ane kushomeka kwakadzika tembiricha kuramba uye kuita brittle pakudziya kwakaderera;

⑨ Zviri nyore kukwegura;

⑩ Mamwe mapurasitiki anonyungudika zviri nyore muzvinonyungudutsa.

Plastiki inogona kukamurwa kuita mapoka maviri: thermosetting uye thermoplastic. Iyo yekutanga haigone kuumbwazve uye kushandiswa, uye iyo yekupedzisira inogona kudzokororwa kugadzirwa. Iko kune marudzi maviri ezvimiro zvepurasitiki polymers:

Yekutanga ndiyo mutsara chimiro, uye musanganiswa wepolymer une chimiro ichi unonzi mutsara wepolymer compound;

Chechipiri chimiro chemhando yemuviri, uye musanganiswa wepolymer une chimiro ichi unonzi body type polymer compound.

Mamwe mapolymers ane cheni dzine matavi, anonzi branched polymers, ayo ari emutsetse chimiro. Kunyange zvazvo mamwe mapolymer ane-cross-links pakati pemamorekuru, ishoma-akabatanidzwa, iyo inonzi network network uye ndeyechimiro chemuviri. Zvimiro zviviri zvakasiyana, zvichiratidza zvinhu zviviri zvakapesana. Iyo mutsara chimiro (kusanganisira branched chimiro) mapolymers ane maitiro e elasticity uye plasticity nekuda kwekuvapo kwemamorekuru akazvimirira, anogona kunyungudutswa muzvinonyungudutsa, anogona kunyungudutswa nekupisa, uye kuve nekuoma kwakaderera uye brittleness. Sezvo pasina macromolecules akazvimirira, iyo polima yakaita semuviri haina elasticity uye plastiki, haigone kunyungudika nekunyunguduka, asi inogona kuzvimba chete, uye ine kuoma kwakanyanya uye brittleness. Purasitiki ine zvimiro zviviri zvemapolymers, thermoplastics yakagadzirwa nemapolymers ane mutsara, uye thermosetting mapurasitiki akagadzirwa neakawanda mapolymer.
