Kugadziriswa kwePolypropylene:
1. Kugadziriswa kwemakemikari ePP
(1) Kugadziriswa kweCopolymerization
(2) Kugadziriswa kwegraft
(3) Kugadziriswa kwekubatanidza
2. Kugadziriswa kwemuviri kwePP
(1) Kugadziriswa kwekuzadza
(2) Kugadziriswa kwekusanganisa
(3) Kugadziriswa kwakawedzerwa
3. Kugadziriswa kwakajeka
Kushandiswa
Polypropylene inoshandiswa zvakanyanya mukugadzira mbatya, magumbeze nezvimwe zvigadzirwa zvefiber, midziyo yekurapa, mota, mabhasikoro, zvikamu, mapaipi ekufambisa, midziyo yemakemikari, nezvimwewo, uye inoshandiswawo mukupakata chikafu nemishonga.
MIRAYIRIDZO
Polypropylene, yakapfupikiswa sePP, chinhu chakasimba chisina ruvara, chisina hwema, chisina chepfu, uye chinopenya.
(1) Polypropylene ipurasitiki yakagadzirwa nethermoplastic ine mashandiro akanaka kwazvo, inova purasitiki isina ruvara uye inopenya uye ine simba rekushandisa thermoplastic. Ine simba rekuchengetedza makemikari, simba rekudzivirira kupisa, simba remagetsi, simba remagetsi uye simba rekugadzirisa rinochengetedza kupisa, nezvimwewo, zvinoita kuti polypropylene ishandiswe nekukurumidza mumichina, mota, midziyo yemagetsi, kuvaka, machira, kurongedza kubva payakatanga. Yakakura uye yakashandiswa munzvimbo dzakawanda dzakadai sekurima, masango, hove uye indasitiri yechikafu.
(2) Nekuda kwepurasitiki yayo, zvinhu zvepolypropylene zviri kutsiva zvigadzirwa zvemapuranga zvishoma nezvishoma, uye simba rayo guru, kuomarara kwayo uye kuramba kupfeka zvakanyanya zvakatsiva mashandiro esimbi zvishoma nezvishoma. Pamusoro pezvo, polypropylene ine mabasa akanaka ekubatanidza nekubatanidza, uye ine nzvimbo yakakura yekushandisa mukongiri, machira, kurongedza nekurima, masango nekubata hove.
ZVINHU
Polypropylene ine zvinhu zvakawanda zvakanaka:
1. Kuwanda kwechinhu ichi kudiki, 0.89-0.91 chete, inova imwe yemhando dzakareruka dzepurasitiki.
2. Hunhu hwakanaka hwemakanika, pamusoro pekudzivirira kukanganiswa, humwe hunhu hwemakanika huri nani pane polyethylene, hunhu hwakanaka hwekuumba.
3. Nekudzivirira kupisa kwakanyanya, tembiricha yekushandiswa nguva dzose inogona kusvika 110-120℃.
4. Hunhu hwakanaka hwemakemikari, hapana mvura inonyungudika, hapana makemikari akawanda anopindirana nawo.
5. Magadzirirwo akachena, asina chepfu.
6. Kudzivirira kwemagetsi kwakanaka.
7. Kujeka kwezvinhu zve polypropylene kuri nani pane kujeka kwezvinhu zve polyethylene zvine density yakakura.
Kurongedza uye Kuchengeta
50/dhiramu, 25kg/dhiramu kana kuti yakagadzirirwa zvinoenderana nezvikumbiro zvemutengi.
Pamusoro peizvi, zvigadzirwa zvedu zvakakurumbira ndeizvifiberglass roving, mameti efiberglassuyewakisi inoburitsa chakuvhuvhu.Tumira email kana zvichidikanwa.
