5, polyvinylidene fluoride PVDF (F2)

1. Matsakaici mai dacewa: mai jurewa ga yawancin sinadarai da kaushi.Yanayin aiki: ≤120°C

2. Features: Ƙarfin ƙwanƙwasa da ƙarfin matsawa sun fi F4, lankwasawa mai kyau da juriya mai sanyi;juriya na yanayi, juriya na radiation, juriya mai haske da tsufa, da dai sauransu. Babban fasalin shine mannewa mai karfi, mai kyau tauri da sauƙin kafawa.

6, polypropylene da aka gyara (GXPP)

1. Matsakaici mai amfani: Maganin da ba kasafai ko mai da hankali ba na maganin ruwa mai ruwa na gishirin inorganic, acid inorganic ko alkali.Yanayin aiki: ≤100°C

2. Features: Yana daya daga cikin mafi sauki robobi.Yawan amfanin sa, ƙwanƙwasa da ƙarfi da ƙarfi da taurin sun fi polyethylene mara ƙarfi.Yana da tsauri mai ban mamaki, juriya mai kyau na zafi, gyare-gyare mai sauƙi da ƙarancin farashi.Bayan gyare-gyaren, ana inganta tasirin, ruwa, da gyare-gyare na elasticity.

7. Polyolefin da aka gyara (GXPO)

1. Matsakaici mai dacewa: nau'o'i daban-daban na acid da alkali salts da wasu kaushi na kwayoyin halitta.Yanayin aiki: ≤110°C

2. Yana da mafi kyawun kayan inganci mai inganci a cikin duniya don rigakafin lalata, anti-static, mara guba da ƙarfi.An yi amfani da shi sosai a cikin manyan kayan aikin juyawa da bawuloli da bututu don sutura.Ana amfani da shi sosai a cikin sinadarai, ƙarfe, abinci, sufuri, magunguna, yadi da sauran masana'antu.

8, polyvinyl chloride (hard) PVC

1. Matsakaici mai dacewa: mai jure ruwa, alkali mai da hankali, acid mara-oxidizing, sarkar hydrocarbon, mai da ozone.Yanayin aiki: ≤60°C

2. Features: high inji ƙarfi, sinadaran kwanciyar hankali da dielectric Properties, man juriya da kuma tsufa juriya ne ma kyau kwarai, sauki weld da bond, farashin ne m.

9. Ultra high kwayoyin nauyi polyethylene (UHMW-PE)

1. Matsakaici mai dacewa: Yana iya tsayayya da kafofin watsa labaru masu lalata daban-daban (sai dai acid, alkali, gishiri, amma acid oxidizing) da kuma kaushi.Yanayin aiki: ≤100°C

2. Features: fice lalacewa juriya, low gogayya coefficient da kai lubricating;kyakkyawan juriya mai tsauri na danniya, juriya mai zafi mai zafi da ƙarancin zafin jiki;kyakkyawan ƙarfi mai ƙarfi, ƙarfin tasiri sosai.Kyakkyawan kwanciyar hankali na sinadarai da juriya ga gajiya;babu adsorption a kan farfajiyar, kyakkyawan rufin lantarki;babu cikakken aiki kamar rashin guba.

10, FRP (phenolic) FRP

1. Matsakaici mai dacewa: maganin kwayoyin halitta, mai mai zafi mai zafi, acid da brine.Yanayin aiki: ≤120°C

2. Features: High inji Properties, low gogayya coefficient a karkashin ruwa lubrication, mai kyau lantarki Properties da low juriya ga acid da alkali lalata, ba sauƙaƙa nakasassu ta canje-canje a cikin zafin jiki da zafi, da sauki forming da low a farashin.
