Hunhu hwePP pepa hunogona kutongwa kubva kune akawanda maficha. Saka ndeipi chiyero chekutenga chePP sheet?
Kubva pakuita kwemuviri kuongorora
Mapepa ePP emhando yepamusoro anofanirwa kuve neakanakisa zvimiro zvemuviri, uye zvakare aine akawanda zviratidzo, senge asina kunhuhwirira, asiri muchetura, wakisi, asinganyunguke mune zvakajairika zvinonyungudutsa, kunyura kwakaderera, uye yakanakisa magetsi ekudzivirira zvinhu. Yakaderera density, yakanaka kuoma, yakanaka dielectric insulation. Low absorption rate. Kupinda kwemhute yemvura kwakaderera. Kugadzikana kwakanaka kwemakemikari. Anti-Japanese War Province.
Cherechedza chitarisiko
Kuongororwa kwepepa rePP kutaridzika kunonyanya kusanganisira kupfava kwepepa, kufanana kwemavara, kupera kwepamusoro, musiyano wemavara, kona isina kukwana, nzvimbo, ukobvu, nezvimwe. Kazhinji kutaura, mashizha akanaka anogona kusvika padanho repamusoro muzviratidzo izvi.
Ndeupi musiyano uripo pakati pePP sheet nePVC sheet?
1. Kusiyana kwemavara:
PP zvinhu hazvigone kuve pachena. Kazhinji, ruvara rwekutanga (ruvara rwechisikigo rwePP texture), beige grey, self-white, nezvimwewo zvinoshandiswa. PVC ine mavara akapfuma, anosanganisira rima grey, light grey, beige, transparent uye zvichingodaro.
2. Kusiyana kwehuremu:
Pepa rePP rine hunyoro hwakaderera pane pepa rePVC, PVC ine density yakakwirira, uye PVC inorema. Kuwanda kwepepa rePP rinowanzoita 0.93, kuwanda kwePVC sheet: 1.58-1.6, uye kuwanda kwepepa rePVC rakajeka: 1.4.
3. Acid-base kushivirira:
Iyo asidhi uye alkali kuramba kwePVC sheet iri nani pane iyo yePP sheet, asi magadzirirwo ayo ane brittle uye akaomarara, inoshingirira kune ultraviolet mwaranzi, inogona kutsungirira kushanduka kwemamiriro ekunze kwenguva yakareba, isingabatike, uye ine huturu hushoma. Nekudaro, PP pepa harivharise ultraviolet mwaranzi, uye ichachinja ruvara kana yaiswa kwairi kwenguva yakareba.
4. Kusiyana kwetembiricha:
Tembiricha yekukwira kwePP ndeye 0 ~ 80 madhigirii Celsius, uye huwandu hwePVC hunosvika 0 ~ 60 degrees Celsius.
5. Chikamu chekushandisa:
PPsheetis inonyanya kushandiswa muasidhi uye alkali inodzivirira midziyo, midziyo yekudzivirira kwezvakatipoteredza, gasi remarara, tsvina yemvura yekurapa, shongwe yekuwachira, kamuri yakachena, semiconductor fekitori uye zvine chekuita nemaindasitiri emidziyo, pakati peiyo PP mashizha akakora anoshandiswa zvakanyanya mukutsikisa ndiro, kutsika ndiro, nezvimwe.
