1. Zvinhu zvakasiyana
PP masutukesiane polypropylene resins.Nekuti homopolymer PP ine brittle zvakanyanya kana tembiricha yakakwira kupfuura 0C, zvinhu zvakawanda zvekutengesa zvePP zvinongoitika zvemacopolymers ane 1 ~ 4% ethylene yakawedzerwa kana ma clamps ane ethylene yemukati.formula copolymer.
A PC muPC suitcase aka "polycarbonate".Polycarbonate isimbi yakaoma thermoplastic resin inowana zita rayo kubva kumapoka eCO3 ari mukati mayo.Ne bisphenol A uye kabhoni oxychloride synthesis.Nzira inonyanya kushandiswa ndeye melt transesterification nzira (bisphenol A uye diphenyl carbonate zvinogadzirwa ne transesterification uye polycondensation).
2. Hunhu hwakasiyana
PP sutukesi: Iyo copolymer-mhando yePP zvinhu ine yakadzika yekupisa yekukanganisa tembiricha (100C), yakaderera pachena, yakaderera gloss, yakaderera kuomarara, asi ine simba rakasimba rekuita.Simba rePP rinowedzera nekuwedzera ethylene yemukati.Iyo Vicat inopfavisa tembiricha yePP ndeye 150C.Nekuda kwehupamhi hwekristaro, chinyorwa ichi chine kunaka kuomarara kwepamusoro uye scratch resistance properties.
PC suitcase: Iyo amorphous thermoplastic resin ine yakanakisa yakazara zvivakwa, ine yakanakisa magetsi ekudzivirira, elongation, dimensional kugadzikana uye makemikari kuramba, simba rakakura, kupisa kupisa uye kutonhora kupikisa;zvakare ine Self-kudzimisa, murazvo wemoto, isina-chepfu, ine ruvara, nezvimwe.
3. Simba rakasiyana
PP sutukesi: ine simba rakasimba rekuita.Iko kuoma kwepamusoro uye kukwenya kuramba zvimiro zvechinhu ichi zvakanakisa.
PC sutukesi: Simba rayo rinogona kusangana nezvinodiwa zvakasiyana kubva kunharembozha kusvika kugirazi rebulletproof.Kuenzaniswa nesimbi, kuoma kwayo hakuna kukwana, izvo zvinoita kuti kutaridzika kwayo kuve nyore kukwenya, asi simba rayo uye kusimba kwakanaka kwazvo, ingave inorema kumanikidza kana general , chero bedzi usiri kuedza kuizunungusa, yakareba zvakakwana.
