Hunhu hwepepa rePP hunogona kutongwa kubva pazvinhu zvakawanda. Saka pepa rePP rinotengwa sei?

Kubva pakuita kwemuviri kusvika pakuongorora

Mapepa ePP emhando yepamusoro anofanira kunge aine hunhu hwakanaka hwemuviri, uye ane zviratidzo zvakawanda, zvakaita sekusanhuwa, kusakuvadza, kuva newakisi, kusanyungudika muzvinonyungudutsa, kusanyungudika zvishoma, uye hunhu hwakanaka hwekudzivirira magetsi. Kuwanda kwakaderera, kuomarara kwakanaka, kusanyungudika kwakanaka kwe dielectric. Kukurumidza kunyura kwemvura. Kupinda kwemvura kwakaderera. Kugadzikana kwakanaka kwemakemikari.

Tarisa chitarisiko

Kuongororwa kwechitarisiko chepepa rePP kunosanganisira kutsetseka kwepepa, kufanana kwemavara, kupedzwa kwemusoro, musiyano wemavara, kona isina kukwana, nzvimbo, ukobvu, nezvimwewo. Kazhinji, mapepa emhando yepamusoro anogona kusvika padanho repamusoro muzviratidzo izvi.

Ndeupi musiyano uripo pakati pepepa rePP nepepa rePVC?

1. Musiyano wemavara:
Zvinhu zvePP hazvigone kujeka. Kazhinji, ruvara rwekutanga (ruvara rwechisikigo rwePP texture), beige grey, self-white, nezvimwewo zvinoshandiswa. PVC ine mavara akapfuma, anosanganisira grey dema, grey light, beige, transparent nezvimwewo.

2. Musiyano wehuremu:
Pepa rePP rine huwandu hwakaderera pane rePVC, PVC ine huwandu hwakanyanya, uye PVC inorema. Huwandu hwepepa rePP hunowanzova 0.93, huwandu hwepepa rePVC: 1.58-1.6, uye huwandu hwepepa rePVC rinoonekera: 1.4.

3. Kushivirira acid-base:
Kusasimba kwePVC sheet neacid nealkali kuri nani pane kwePP sheet, asi magadzirirwo ayo akaomarara uye akaomarara, haapiswi nemwaranzi ye ultraviolet, anogona kutsungirira shanduko yemamiriro ekunze kwenguva yakareba, haatsve, uye ane chepfu shoma. Zvisinei, PP sheet haidziviriri mwaranzi ye ultraviolet, uye inochinja ruvara kana ikabatwa nayo kwenguva yakareba.

4. Musiyano wekupisa:
Kukwira kwetembiricha yePP i0 ~ 80 degrees Celsius, uye huwandu hwePVC i0 ~ 60 degrees Celsius.

5. Mashandisirwo azvo:
PPsheet inonyanya kushandiswa mumidziyo inodzivirira acid nealkali, michina yekudzivirira zvakatipoteredza, gasi remarara, michina yekurapa mvura yakasviba, shongwe yekuwachisa, imba yakachena, fekitori yesemiconductor nezvimwe zvishandiso zvemaindasitiri, pakati pazvo machira ePP akakora anoshandiswa zvakanyanya mustamping plate, stamping plate, nezvimwewo.
