Chii Chinonzi Polypropylene ine Furo?
Tsanangudzo uye Maumbirwo
Polypropylene ine furoimhando ye polypropylene foam inogadzirwa nekuwedzera polymer ne furo agent. Maitiro aya anochinja marongerwo emamorekuru echinhu ichi, zvichigadzira chimiro chemasero akavharwa akazadzwa nemabubble madiki egasi. Mugumisiro wacho ichinhu chakareruka chine hunhu hwakasiyana. Kusiyana ne polypropylene yakajairwa, iyo yakasimba uye yakakora, polypropylene ine furo agent ine masero madiki akawanda, akavharirwa anoderedza huremu uye anovandudza insulation. Kushandisa physical blowing agent, senge carbon dioxide, kunobatsira kuumba masero aya panguva yekugadzira. Chimiro ichi chinopa physically foam polypropylene tekinoroji yayo yepamusoro ye microporous foam, zvichiita kuti ive yakakodzera kushandiswa kwakawanda kunoda simba uye huremu hushoma.
Matanho makuru ekugadzira PP ine furo anosanganisira kuita kuti furo rive reactive, soluble foaming, pressure quench foaming, uye kuvandudzwa kwe compression molding. Nzira imwe neimwe inoshandisa kemikari kana physical blowing agent kugadzira furo. Semuenzaniso, pressure quench foaming inoshandisa CO2 kugadzira chimiro chemasero akavharwa, nepo kuvandudzwa kwe compression molding kunoshandisa azodicarbonamide kudzora density uye saizi yemasero.
Zvinhu Zvikuru zvePolypropylene Foam
Foam yePolypropylene inoonekwa seyakasiyana neyayo yemuchina uye yekupisa. Chimiro chemasero akavharwa chinopa kugadzikana kwakanaka kwechimiro uye insulation yakanaka yekupisa. Sezvo huwandu hwechinhu chinofefetera huchiwedzera, furo rinova rakareruka uye conductivity yaro yekupisa inoderera, zvinoreva kuti rinochengeta kupisa mukati kana kunze zvinobudirira. Zvisinei, magasi makuru anogona kuderedza kuomarara uye simba remuchina, asi chinhu chacho chinoramba chichidzivirira kukuvadzwa kwakasimba. Foam yePolypropylene inodzivirirawo makemikari nehunyoro, zvichiita kuti igare kwenguva refu munzvimbo dzakaoma. Izvi zvinoita kuti polypropylene ine furo ive sarudzo yepamusoro pakati pemapolymer ane furo. Inoshandiswawo muzvigadzirwa zvakaita se microporous foamed polypropylene sheet, uko kureruka uye insulation zvakakosha.
Mabhenefiti Makuru eHigh Foamed PP Profiles
Kubata Kwakareruka uye Kuri Nyore
Mapurofayi epurasitiki ane furo anonyanya kuoneka nekureruka kwawo. Maumbirwo epurasitiki ine furo akavharwa anoderedza kuwanda uku achichengetedza simba. Izvi zvinoita kuti kubata nekufambisa zvive nyore. Vashandi vanogona kusimudza nekufambisa mapaneru makuru kana zvikamu zvisina simba. Mumotokari nekuvaka, kureruka kunobatsira kuderedza kushandiswa kwemafuta uye kunoita kuti kuiswa kukurumidze. Kureruka uye simba rakawanda repurasitiki ine furo zvinorevawo kuti zvinhu zvishoma zvinodiwa kuti zvishande zvakafanana. Izvi zvinoita kuti kushandiswa kwepurasitiki ine furo kushandiswe zvakanaka mumaindasitiri mazhinji.
Kudzivirira Kupisa Kwepamusoro
Kudzivirira kupisa chinhu chakakosha che pp ine furo. Chimiro chemasero akavharwa chinobata mhepo, izvo zvinoderedza kutamiswa kwekupisa. Foam yePolypropylene inopa mashandiro akanaka ekudzivirira kupisa munzvimbo dzinopisa nedzinotonhora. Izvi zvinobatsira kuchengetedza mukati meimba zvakanaka uye zvinoderedza mari yemagetsi. Muzvinhu zvekuvaka, mashandiro ekudzivirira kupisa zvinoreva kuti madziro nematenga zvinogara zvichitonhorera muzhizha uye zvinodziya muchando. Mumapakeji, kudzivirira kupisa kunodzivirira zvinhu zvinonzwa tembiricha panguva yekutumira. Polypropylene ine furo inopawo kudzivirira ruzha, izvo zvinoderedza kutapurirana kweruzha mudzimba nemotokari. Kusanganiswa kwekudzivirira kupisa nekudzivirira ruzha kunoita kuti ma profiles aya akwane kune akawanda mashandisirwo.
Kuramba Kwemakemikari uye Kugara Kwenguva refu
Mapurofayi epurasitiki ane furo anoratidza kusasimba kwakasimba kumakemikari akawanda. Izvi zvinoita kuti akwanise kushandiswa munzvimbo dzakaoma dzemaindasitiri. Tafura iri pazasi inoratidza kuti polypropylene ine furo inoramba yakasimba sei mushure mekusangana nemakemikari akajairika:
| Kemikari | Kuchengetedza Simba Rekusimba | Kuchengetedza Simba reMhedzisiro |

Foam yepolypropylene inochengetedza hunhu hwayo hwemuchina kunyangwe mushure mekusangana nemakemikari. Kugara kwenguva refu uku kunoreva hupenyu hurefu hwebasa uye kusanyanya kugadziriswa. Kugadzikana kwekupisa kwakanyanya kunowedzera imwe nhanho yekudzivirira, zvichiita kuti ma profiles aya ashande zvakanaka mumamiriro ezvinhu akaomarara.
Kuomarara, Kusimba, uye Kuramba Kukanganiswa
Polypropylene ine furo inopa musanganiswa wakasiyana wekuomarara uye kusimba. Izvi zvinoreva kuti chinhu ichi chinoramba kukotama nekupwanyika kana chamanikidzwa. Hunhu hwakanaka hwemuviri uye hwemakanika hwe pp ine furo hunoita kuti ive yakakodzera zvikamu zvinofanirwa kugamuchira kuvhunduka kana kurovera. Tafura inotevera inoratidza mashandiro anoita polypropylene foam mukuyedzwa kwekuparara:
| Kumhanya Kwekuyedza (mm/s) | Mwero weKumanikidzwa Kweropa (1/s) | Modulus yeElastic (MPa) | Kushushikana Kwepamusoro (MPa) | Kumanikidzwa Kwezita Pakuzorora (%) |
