Iindaba

Umgangatho wephepha lePP unokugwetywa kwiinkalo ezininzi. Ngoko ke yintoni umgangatho wokuthenga wephepha lePP?

Ukususela ekusebenzeni komzimba ukuhlalutya

Amaphepha e-PP akumgangatho ophezulu kufuneka abe neempawu ezibalaseleyo zomzimba, kwaye abe nezalathi ezininzi, ezinje ngokungenavumba, okungeyotyhefu, i-waxy, enganyibilikiyo kwizinyibilikisi ngokubanzi, ukufunxa okuphantsi, kunye neempawu ezibalaseleyo zokugquma umbane. Ukuxinana okuphantsi, ukuqina okuhle, ukugquma kakuhle kwedielectric. Izinga lokufunxa eliphantsi. Umphunga wamanzi ukufikeleleka kuphantsi. Uzinzo oluhle lweekhemikhali. IPhondo leMfazwe elichasene neJapan.
Qwalasela inkangeleko

Ukuhlolwa kwenkangeleko yephepha lePP ikakhulu ibandakanya ukucaca kwephepha, ukufana kombala, ukugqitywa komphezulu, umahluko wombala, i-angle engonelanga, indawo, ubukhulu, njl.

Uthini umahluko phakathi kwephepha lePP kunye nephepha lePVC?

1. Umahluko wombala:
Izinto zePP azinakucaca. Ngokuqhelekileyo, umbala ophambili (umbala wendalo we-PP texture), i-beige grey, i-self-white, njl. I-PVC inemibala ecebileyo, kuquka ingwevu emnyama, ingwevu ekhanyayo, i-beige, i-transparent njalo njalo.

2. Umahluko wobunzima:
Iphepha lePP linoxinano olusezantsi kunephepha lePVC, iPVC inoxinzelelo oluphezulu, kunye nePVC inzima. Ubuninzi bephepha le-PP ngokuqhelekileyo ngu-0.93, ubuninzi bephepha le-PVC: 1.58-1.6, kunye nobuninzi bephepha le-PVC elicacileyo: 1.4.

3. Ukunyamezela i-Acid-base:
I-asidi kunye nokumelana ne-alkali yephepha le-PVC lingcono kunephepha le-PP, kodwa ukuthungwa kwayo kuncinci kwaye kunzima, kunokumelana nemitha ye-ultraviolet, inokunyamezela ukutshintsha kwemozulu ixesha elide, ayinakutsha, kwaye inetyhefu encinci. Nangona kunjalo, iphepha le-PP aliyivali imisebe ye-ultraviolet, kwaye iya kutshintsha umbala xa ibonakaliswe kuyo ixesha elide.

4. Umahluko wobushushu:
Uluhlu lokunyuka kobushushu bePP yi-0 ~ 80 degrees Celsius, kwaye uluhlu lwePVC luyi-0 ~ 60 degrees Celsius.

5. Ubungakanani besicelo:
I-PPsheetis isetyenziswa ikakhulu kwizixhobo ze-asidi kunye ne-alkali ezixhathisayo, izixhobo zokukhusela indalo, inkunkuma yegesi, izixhobo zokucoca amanzi amdaka, inqaba yokuhlamba, igumbi elicocekileyo, umzi-mveliso we-semiconductor kunye nezixhobo ezinxulumene nemizi-mveliso, phakathi kwazo amaxwebhu ashinyeneyo ePP asetyenziswa ngokubanzi kwipleyiti yokutampa, ipleyiti yokutywina, njl.
