Iindaba

Umgangatho wephepha le-PP ungajongwa ngokweenkalo ezininzi. Ngoko ke ithini imigangatho yokuthenga yephepha le-PP?

Ukususela ekusebenzeni ngokomzimba ukuya ekuhlalutyeni

Amaphepha e-PP asemgangathweni ophezulu kufuneka abe neempawu ezibonakalayo ezibalaseleyo, kwaye abe neempawu ezininzi, ezifana nokungavumba, ukungatyisi, ukuba ne-wax, ukunganyibiliki kwizinyibilikisi ngokubanzi, ukufunxwa okuphantsi, kunye neempawu zokufakelwa kombane ezibalaseleyo. Uxinano oluphantsi, ukuqina okuhle, ukufunxwa okuhle kwe-dielectric. Izinga lokufunxwa eliphantsi. Ukungenela komphunga wamanzi kuphantsi. Uzinzo oluhle lweekhemikhali. Iphondo leMfazwe echasene neJapan.
Jonga inkangeleko

Ukuhlolwa kwenkangeleko yephepha le-PP kubandakanya ikakhulu ukuba tyaba kwephepha, ukufana kombala, ukugqitywa komphezulu, umahluko wombala, i-engile enganeleyo, indawo, ubukhulu, njl. Ngokubanzi, amaphepha asemgangathweni anokufikelela kwinqanaba eliphezulu kwezi zikhombisi.

Yintoni umahluko phakathi kwephepha lePP kunye nephepha lePVC?

1. Umahluko wombala:
Izinto zePP azinakubonakala. Ngokubanzi, kusetyenziswa umbala oyintloko (umbala wendalo wobume bePP), umbala ongwevu oluhlaza okwesibhakabhaka, umbala omhlophe okhanyayo, njl. njl. I-PVC inemibala etyebileyo, kuquka umbala ongwevu omnyama, umbala ongwevu okhanyayo, umbala ongwevu, umbala ocacileyo njalo njalo.

2. Umahluko kubunzima:
Iphepha le-PP linoxinano oluphantsi kunephepha le-PVC, i-PVC inoxinano oluphezulu, kwaye i-PVC inzima. Uxinano lwephepha le-PP ngokubanzi yi-0.93, uxinano lwephepha le-PVC: 1.58-1.6, kwaye uxinano lwephepha le-PVC elicacileyo: 1.4.

3. Ukunyamezelana kwe-asidi-base:
Ukumelana ne-asidi kunye ne-alkali kwephepha le-PVC kungcono kunokwephepha le-PP, kodwa ubume balo buthambile kwaye buqinile, alunakumelana nemitha ye-ultraviolet, lunokunyamezela utshintsho lwemozulu ixesha elide, alutshi, kwaye lunobuthi obuncinci. Nangona kunjalo, iphepha le-PP aliyithinteli imisebe ye-ultraviolet, kwaye liya kutshintsha umbala xa livezwa kulo ixesha elide.

4. Umahluko kubushushu:
Uluhlu lokunyuka kwamaqondo obushushu e-PP yi-0 ~ 80 degrees Celsius, kwaye uluhlu lwe-PVC yi-0 ~ 60 degrees Celsius.

5. Ububanzi besicelo:
IiPPsheet zisetyenziswa kakhulu kwizixhobo ezichasene ne-asidi kunye ne-alkali, izixhobo zokukhusela okusingqongileyo, igesi emdaka, izixhobo zonyango lwamanzi amdaka, inqaba yokuhlamba, igumbi elicocekileyo, ifektri ye-semiconductor kunye nezixhobo zoshishino ezinxulumene noko, phakathi kwazo amaphepha amakhulu e-PP asetyenziswa kakhulu kwipleyiti yokunyathela, ipleyiti yokunyathela, njl.njl.
