Kazhinji kutaura, kutsvuka kwezvigadzirwa zvepurasitiki kunokonzerwa nekuchembera kana kuparara kwezvinhu.Kazhinji,PPkunokonzerwa nekuchembera (degradation).Pamusana pekuvapo kwemapoka emativi pa polypropylene, kugadzikana kwayo hakuna kunaka, kunyanya munyaya yechiedza.Kazhinji, light stabilizer inowedzerwa.NezvePE, sezvo pasina hwaro hweparutivi, hapana zviitiko zvakawanda zveyero mukugadziriswa kwakawanda kana kushandiswa kwekutanga.PVCichashanduka yero, iyo inonyatso hukama kune formula yechigadzirwa.Kutaura zvakajeka, inonzi oxidation.Iyo yepamusoro yemamwe masterbatches iri nyore kuve oxidized, saka zvinodikanwa kuita kurapa kwepamusoro pane masterbatches.
Mukuwedzera kune zvakashata zvinowedzera uye zvakasvibiswa muhurongwa, ndinofunga kuti zvinonyanya kukonzerwa nekukwegura.Kuwedzera akakodzera maantioxidant masisitimu uye anti ultraviolet agents anogona kuvandudza kutsvuka kwePE nePP, asi mazhinji akadzivirira phenolic antioxidant masisitimu pachawo achaunza kutsvuka kudiki.Mukuwedzera, mamwe maantioxidant systems uye anti ultraviolet agents ane maitiro ekudzivirira, saka chenjerera paunenge uchivashandisa.Polymer lubricant inowedzerwa kuti igadzire inoyerera yepolymer fluoropolymer firimu pamadziro emuchina, kunatsiridza extrusion processing performance, extrusion pressure uye kugadzirisa tembiricha yepololefin resin, kunatsiridza kunaka kwechigadzirwa uye goho, kuderedza mutengo wekugadzira, kuderedza kana kubvisa kunyunguduka, uye kuderedza zvimedu. rate.
1. Pane zvinhu zvakasvibirira zvinonzi plasticizer muzvigadzirwa zvepurasitiki, izvo zvinonyanya kuita basa rekudzivirira kukwegura, asi rinoputika mumhepo, saka kana plasticizer yaderedzwa, ruvara ruchapera, uye elasticity yepurasitiki ichadererawo. , iyo ichaita kuti iite brittle uye yero.
2. Iko kuchena kwemabhokisi epurasitiki mushure mekugadzirwa kana kushandiswa kwenguva yakareba kunokonzerwa nekukwegura kwezvinhu zvinoshandiswa, kana kuti zvinogona kugadzirwa mushure mekuora.Chinhu chakanyanya kuomarara mamwe mabhokisi machena epurasitiki, senge mamwe machena mabhokisi ekuchinja uye madhiramu epurasitiki.
3. Chikonzero chinowanzoitika ndechekukwegura kwezvigadzirwa zvepurasitiki.Chikonzero ndechekuti polypropylene ine kumusoro kudivi kurwisa.Kugadzikana kwayo hakuna kunaka kwazvo, kunyanya munyaya yekuoma kwenguva refu.
4. Nokudaro, kuita mapurasitiki machena kwenguva refu, edza kudzivisa chiedza chakasimba.Kana yakabatana nechikafu, edza kushandisa mapurasitiki akajeka uye asina ruvara.Kana iwe uchida kubvisa chiitiko ichi, iwe unogona kuwedzera imwe chiyero chakatsetseka stabilizer.
