I-PP Board (I-PolyPropylene Board), impahla ye-polymer esetshenziswa kabanzi kwizicelo zesimanje zezimboni nabezempi, ihlanganisa ulwazi lwezinhlangothi eziningi kwisayensi yezinto zokwakha, ukuhlaziya okwenziwe ngomshini, ubuchwepheshe bokucubungula kanye nokuguquguquka kwemvelo. Ukuqonda kakhulu i-Design Logic yeBhodi ye-PP, kufanele siqale kwezinto ezibonakalayo ezingokwemvelo bese sihlaziya kancane kancane i-logic ebalulekile ebandakanyeka ekubumbeni okuhlelekile, ukusebenza kahle okusebenzayo, futhi isikhathi eside - ukuqinisekiswa kwesikhathi sokuthembeka.
1. Izinto ezisetshenziswayo ezihlanzayo: izingqinamba eziyisisekelo ze-PP Board Design
Idizayini yeBhodi ye-PP icindezelwa ikakhulukazi ngesakhiwo samangqamuzana nezindawo ezibonakalayo ze-polypropylene. I-Polypropylene iyi-semi - eyenziwe nge-crystalline thermoplastic eyakhiwe yi-polymerization ye-propylene monomers ukwakha ama-polymers aqondile ngamaqembu we-methyl ({- ch₃) kwi-backbone. Ukuvama kwamakhekhe alo amangqamuzana kunquma i-crystaltaltity yokwenziwa (imvamisa engama-40% -70%). Lesi sakhiwo sinika i-PP Board yayo eyisisekelo emithathu yezakhiwo: isisindo esikhanyayo namandla aphezulu, ukuhlanzeka kwamakhemikhali, nokuzwela okushisa.
Ngokombono owenziwa ngomshini, ishidi le-PP linokubumbana kokuphela kuka-0,9 -, kepha i-1/2 Ibonisa futhi ukumelana nokungamelana kahle kwe- - Iphikisana nokuqhekeka kwe-brittle ngaphansi kwemithwalo ephindaphindwayo, okwenza ukuthi ilungele izinhlelo zokusebenza ezidinga izicelo zesikhathi eside zomthwalo (njengezembozo zeshalofu kanye nesembozo sokuvikela imishini). Kodwa-ke, i-modulus yayo ephansi (cishe i-1-2 GPA) isho ukuthi i-deform ebalulekile kungenzeka ukuthi yenzeke ezindaweni ezinama-spans amakhulu noma ukugxila okuphezulu, okudingayo ukulungiswa kokuqamba ngokukhuphuka noma okuqinisiwe.
Chemical stability is another major advantage of PP sheet: it is resistant to most acid, alkali, and salt solutions (such as sulfuric acid below 80% concentration and sodium hydroxide at 20%), as well as organic solvents (with a few exceptions, such as concentrated nitric acid and chloroform). This makes it a preferred choice for applications such as chemical tank linings and laboratory countertops. However, it should be noted that high temperatures (>I-80 degree) noma ukuvezwa kwe-UV okuhlala isikhathi eside kungadala ukuqhekeka kwama-molecular, okuholela ekugugeni (kuboniswe njenge-brittleness kanye nokuqonda). Ngakho-ke, izinhlelo zokusebenza zangaphandle zidinga ukwengeza ama-UV inhibitors noma izimbobo zangaphandle zokuvikelwa.
2. I-Logic Design Logic: Izidingo Zokusebenza Zokulinganisa Nezindlela Zokuhluleka
Idizayini ethile yamashidi e-PP kufanele agxile kuwo "umsebenzi ohlosiwe" kanye "nezindlela ezingaba khona zokwehluleka." Izidingo ezijwayelekile ezisebenzayo zifaka phakathi umthwalo
1. Layisha -}} I-Eadring Design Design: Ukuhlelwa okuhlelekile kokuqina namandla
Lapho amashidi e-PP esetshenziswa emthanjeni Ngokusho kwamafomula wezinto ezibonakalayo, ukunqotshwa okuphezulu komzimba osekelwayo osekelwayo ngaphansi komthwalo osatshalaliswa ngokufanayo Ngenxa yenani eliphansi le-e yamaphaneli e-PP, uma kusetshenziswa isakhiwo seplate eliphansi ngqo, ukuvela ngaphansi kwezikhala ezinde kuzodlula ukusebenza okudingekayo (ngokuvamile, ukuvela okuvumelekile kungaphansi noma okulingana no-1/200). Izixazululo zifaka:
• Ukwanda okukhulu: ngakho konke ukuphindaphindwa kobukhulu, i-Iavering ye-I Inani liyanda ngamahlandla ayi-8 (i {= Ingxenye ye-{3}}), kepha lokhu kukhulisa izindleko nesisindo.
• Ukuqiniswa okushumekiwe: Ngokucindezela izimbambo ze-Longitudinal / Transverse (1/2 / 3 of the panel ubukhulu, okunesikhala esingaphansi noma ezilingana nezikhathi ezi-3 zesakhiwo kungandiswa ngo-30% -50%, ngenkathi kunciphisa ukusetshenziswa kwezinto ezibonakalayo.
• Ukuqiniswa kwe-composite: Ukuhlanganiswa nabasizi njengokuthi i-fiber fiber (gf) ne-calcium carbonate (caco₃), noma ukunamathisela i-mesh yensimbi (njenge-aluminium foil) ebusweni, lezi zinto ze-heterogenes) zingathuthukisa ubumbano.
2. I-Seaning and Connection Design: ukubeka phambili ukuhambisana kwe-interface
Amaphaneli we-PP asetshenziswa kakhulu kuzinhlelo zokusebenza ezifana nokubekwa uphawu kwephayiphu kanye nokuhlukaniswa kwebhokisi. Idizayini yabo yokuxhumana kumele ibhekane nephuzu lobuhlungu lokuhlanganiswa okunzima kwezinto ezibonakalayo ze-polymer. I-Polypropylene inamandla aphansi kakhulu (cishe ama-30 mn / m), okwenza kube nzima ukwakha ibhondi ephumelelayo enezindawo ezinama-adhesives (njenge-epoxy resin). Ngakho-ke, izindlela zokujoyina ngokomzimba zikhethwa kulo mklamo:
• okushisayo
• Isiqeshana / i-Bolt okusheshayo: amaviki avinjelwe epulasitiki amapulasitiki, noma avikelekile nge-Pre - Ukutholwa kwezimbobo ezibiwe kanye nokuzithandela ama-PP}.
• I-Sealant -} I-Adhesive Bonding iyadingeka, khetha i-ejenti yokwelashwa ekhethekile ye-PP (qala ukufaka i-ejenti yokwelashwa ukuze wandise amandla angaphezulu, noma usebenzise i-sealive eguquguqukayo) ukugcwalisa igebe.
3. Idizayini yokuguquguquka kwezemvelo: Anti - Ukukhula nokusebenza okusebenzayo
Ngezindawo ezikhethekile (ezinjengezangaphandle, eziphakeme
• I-UV - Ukuvinjwa okuvimbela i-carbon (cishe ama-2%) noma ama-organic UV ama-UV) amunca noma anciphise ukuqhekeka kwensimbi ye-UV futhi anciphise impilo yangaphandle ye-IV kusuka eminyakeni eyi-1-2 kuya ngaphezulu kweminyaka emi-5.
• Idizayini ephethe / ye-antistatic Ilungele abathwali bezakhi ze-elekthronikhi kanye nokufakelwa phansi kwama-antistatic eziteshini zikaphethiloli.
• Antibacterial Design: Loading silver ions, zinc ions, or nano-titanium dioxide (TiO₂) inhibits bacterial growth through photocatalysis or ion release (antibacterial rate >90%). Esetshenziswa kakhulu ekusebenzeni kokudla okumanzi kanye namadivayisi wezokwelapha.
I-3
Idizayini yeshidi ye-PP kumele futhi ijwayele izici zayo zokucubungula. Izinto ze-thermoplastic zingakhiwa ngezindlela ezinjengokubumba okunjengokucindezela, nokucindezela okushisayo, kepha izinqubo ezahlukene zibeka ukulinganiselwa okuthile ngemininingwane ehlelekile. Ngokwesibonelo:
• Ubukhulu bokuqina: ukubekezelelana okukhulu kwamashidi e-PP angemuva ngokujwayelekile ± 0.5mm. Uma ukwakheka kudinga ukucaciswa okuphezulu (isib.,
• Ukujikeleza kwe-Corner kanye ne-angle eyindilinga Ngakho-ke, wonke amakhona ekwakhiweni kufanele ahlanganiswe (r mkhulu kune- noma alingane ne-1mm kunconyiwe). Ngaphezu kwalokho, uma ukucubungula kwesibili (isib
• Ukuvumelana kwe-Welding: Uma ukwakheka kufaka phakathi ukuhlukanisa, qiniseka ubukhulu obungaguquki odongeni oluhlanganisiwe (ukuphambuka ngaphansi noma okulingana no-10%). Ngaphandle kwalokho, indawo encane izoncibilika futhi igeleze kuqala ngesikhathi sokushisa esishisayo incishise, kungavimba indawo enkulu ukuba ihlanganise ngokuphelele.
Isiphetho: Imephu yesayensi evela emcabangweni wokuzijwayeza
Idizayini yamaphaneli e-PP empeleni iyindlela yokulinganisela emithathu ye- - yendlela "yezakhiwo ezibonakalayo, izidingo ezisebenzayo, kanye nezingqinamba zokucubungula." Abaqambi kumele baqonde ngokujulile ngokuziphatha kwamangqamuzana kwe-polypropylene (njengomthelela we-crystallollinity ngobulukhuni), imithetho yohlelo lwesakhiwo (njengokuqinisa imingcele yokucubungula (njengemizwa yokusebenza okuncane) ukufeza ukusebenza kahle kanye nokusebenza kahle. Ngentuthuko kubuchwepheshe bokuguqulwa (njengama-nanocomelites kanye nokuthuthukiswa kwe-bio -, izimiso zokuqamba amaphaneli e-PP zizoqhubeka nokuvela, ukuhlinzeka ngezixazululo ezithembekile zezinto ezisetshenziswayo zohlelo olungasindi futhi olusebenzayo.
