Nhanganyaya kune akasiyana akajairwa zvimiro zvePP isiri-yakarukwa jira
(1) Zvimiro zvemuviri: PP isiri-yakarukwa jira isiri-chepfu, isina kuravira mukaka chena yakakwira crystalline polymer, inova imwe yemhando dzakareruka dzemapurasitiki ese parizvino.Inonyanya kugadzikana kumvura, uye mvura yaro yekunyura mumvura inongova 0.01% mushure me14h.Iyo molecular huremu ndeye 80,000 ~ 150,000, ine yakanaka formability.Nekudaro, nekuda kweiyo shrinkage yakakura, zvigadzirwa zvekutanga zvemadziro zviri nyore kudonha, uye pamusoro pezvigadzirwa zvinopenya uye zviri nyore kuisa ruvara.
(2) Mechanical zvimiro: PP isina-yakarukwa jira rine yakakwira crystallinity uye yakajairwa chimiro, saka ine yakanakisa mechaniki zvivakwa.Simba rayo, kuoma uye elasticity yakakwirira kudarika ye-high-density PE (HDPE).Chinhu chakatanhamara ndechekupeta kuneta kuramba (7 × 10 ^ 7) Yechipiri kuvhura nekuvhara yakakotama pasina kukuvara, uye iyo yakaoma friction coefficient yakafanana nenylon, asi yakaderera kune nylon pasi pemafuta ekuzora.
(3) Thermal performance: PP isiri-yakarukwa jira rine yakanaka yekupisa, nzvimbo yekunyunguduka i164 ~ 170 ℃, uye zvigadzirwa zvinogona kugadzirwa patembiricha inopfuura 100 ℃.Pasi pekuita pasina simba rekunze, haizokanganise pa150 ℃.The embrittlement tembiricha iri - 35 ℃, izvo zvichaitika pazasi - 35 ℃, uye kupisa kuramba hakuna kunaka sePE.
(4) Kugadzikana kwemakemikari: PP isina-yakarukwa jira ine yakanaka kugadzikana kwemakemikari.Mukuwedzera pakuderedzwa neasidhi, inenge yakagadzikana kune mamwe makemikari reagents.Nekudaro, yakaderera molecular uremu aliphatic hydrocarbons, anonhuwirira hydrocarbons, nezvimwe zvinogona kupfavisa uye kuzvimba PP isiri-yakarukwa jira, uye kugadzikana kwemakemikari kunovandudzwa zvakare nekuwedzera kwekristaro.Naizvozvo, PP isiri-yakarukwa jira rakakodzera kugadzira eRussia neChinese makemikari pombi uye zvishongedzo, zvine yakanaka anti-corrosion effect.
(5) Kuita kwemagetsi: Iyo yakakwira frequency insulation kuita kwejira risiri rakarukwa rakanaka.Nekuti inenge isingatore mvura, iyo insulation performance haina kukanganiswa nehumidity.Iine high dielectric coefficient.Nekuwedzera kwekushisa, inogona kushandiswa kugadzira zvigadzirwa zvemagetsi zvinopisa.Iyo yekuputsika voltage zvakare yakakwira zvakanyanya, uye yakakodzera kune zvemagetsi zvinhu.Yakanaka voltage kuramba uye arc kuramba, asi yakakwira static magetsi, zviri nyore kuchembera kana uchisangana nemhangura.
(6) Kuramba kwemamiriro ekunze: machira asiri akarukwa anonamira zvakanyanya kune ultraviolet mwenje, uye kuramba kuchembera kunogona kuvandudzwa nekuwedzera zinc oxide thiopropionic acid lauryl ester, kabhoni dema senge milky chena filler, nezvimwe.
