Ikhwalithi yeshidi le-PP ingahlulelwa ngezici eziningi. Ngakho-ke iyini indinganiso yokuthenga yeshidi le-PP?
Kusukela ekusebenzeni ngokomzimba kuya ekuhlaziyeni
Amashidi e-PP asezingeni eliphezulu kufanele abe nezakhiwo zomzimba ezinhle kakhulu, futhi abe nezinkomba eziningi, njengokungabi nephunga, okungenabo ubuthi, okufana ne-wax, okungancibiliki ezinyibilikisini ezijwayelekile, ukumuncwa okuncane, kanye nezakhiwo ezinhle kakhulu zokuvikela ugesi. Ukuminyana okuphansi, ukuqina okuhle, ukuvikela okuhle kwe-dielectric. Izinga lokumuncwa eliphansi. Ukumuncwa kwamanzi kuphansi. Ukuqina okuhle kwamakhemikhali. Isifundazwe Esilwa Nempi YaseJapan.
Qaphela ukubukeka
Ukuhlolwa kokubonakala kweshidi le-PP kuhlanganisa kakhulu ukuba yisicaba kweshidi, ukufana kombala, ukuqeda ubuso, umehluko wombala, i-engeli enganele, indawo, ukujiya, njll. Ngokuvamile, amashidi ekhwalithi enhle angafinyelela ezingeni eliphezulu kulezi zinkomba.
Uyini umehluko phakathi kweshidi le-PP neshidi le-PVC?
1. Umehluko wombala:
Izinto ze-PP azikwazi ukucaca. Ngokuvamile, kusetshenziswa umbala oyinhloko (umbala wemvelo wokuthungwa kwe-PP), umpunga oluhlaza okotshani, omhlophe ozimele, njll.. I-PVC inemibala ecebile, kufaka phakathi umpunga omnyama, umpunga okhanyayo, umpunga, obonakalayo njalo njalo.
2. Umehluko wesisindo:
Ishidi le-PP linobuningi obuphansi kuneshidi le-PVC, i-PVC inobuningi obuphezulu, kanti i-PVC inzima. Ubuningi beshidi le-PP ngokuvamile bungu-0.93, ubuningi beshidi le-PVC: 1.58-1.6, kanye nobuningi beshidi le-PVC elibonakalayo: 1.4.
3. Ukubekezelelana kwe-asidi-base:
Ukumelana kweshidi le-PVC nge-asidi kanye ne-alkali kungcono kunokweshidi le-PP, kodwa ukuthungwa kwalo kuyaphuka futhi kuqinile, liyamelana nemisebe ye-ultraviolet, lingabekezelela ushintsho lwesimo sezulu isikhathi eside, alishi, futhi linobuthi obuncane. Kodwa-ke, ishidi le-PP alivimbeli imisebe ye-ultraviolet, futhi lizoshintsha umbala uma livezwa kulo isikhathi eside.
4. Umehluko wokushisa:
Ububanzi bokukhuphuka kwezinga lokushisa le-PP bungu-0 ~ 80 degrees Celsius, kanti ububanzi be-PVC bungu-0 ~ 60 degrees Celsius.
5. Ububanzi bokusetshenziswa:
Ama-PPsheet asetshenziswa kakhulu emishinini engamelani ne-asidi ne-alkali, imishini yokuvikela imvelo, igesi engcolile, imishini yokwelapha amanzi angcolile, umbhoshongo wokuwasha, igumbi elihlanzekile, ifektri ye-semiconductor kanye nemishini yezimboni ehlobene, phakathi kwawo amashidi amakhulu e-PP asetshenziswa kabanzi epuletini lokunyathela, epuletini lokunyathela, njll.
Isikhathi sokuthunyelwe: Feb-21-2023
