Ibhodi ye-PP (iBhodi yePolyPropynene), i-polymer isetyenziswe ngokubanzi kwizicelo zanamhlanje kunye nezixhobo, zidibanisa ulwazi lwezinto ezininzi kwizixhobo zenzululwazi, kunye netekhnoloji yoomatshini, kunye nokuzimela okusingqongileyo. To deeply understand the design logic of PP board, we must start from the material's inherent properties and gradually analyze the core logic involved in structural design, functional optimization, and long-term reliability assurance.
I-1. Iipropati zeMicimbi yeZinto zeMicimbi: Isithintelo esisiseko soyilo lwebhodi ye-PP
Uyilo lweBhodi ye-PP ngokuyintloko lunyanzelwa yimo yemolekyuli kunye neepropathi zomzimba zePolypropylene. I-Polypropylene yi-semi -}}}}} i-thertalistic ye-polymeristic ye-propylenes kwi-folymers ye-propylene ukuba yenze i-polymers ye-methyl ({2}} kumqolo. Isigidimithi sayo seemolekyuli sibeka i-crystallity ye-crystallity ye-40% -70%). Olu lwakhiwo lunika iBhodi ye-PP yePropathi yayo yesiseko: Ubunzima bokukhanya kunye namandla aphezulu, ubushushu bekhemikhali, kunye nobushushu bemvakalelo.
Ukusuka kwimbono yomatshini, i-PP ye-PP inobuninzi be-0.9 {6} - i-0.9}} i-000 yentsimbi (7}} i-40 MPA ngoongezwa kwi-fiber yeglasi). Ikwabonisa ukungavisisani okugqwesileyo okutshabalayo - Ihlala ixhathisa ukwaphuka kwemithwalo ephindaphindiweyo, eyenza ilungele izicelo ezifuna izicelo ezifuna izicelo ezifuna imithwalo yexesha elide (ezinje ngezixhobo zokukhusela izixhobo). Nangona kunjalo, i-dustic yayo ye-elastic (malunga ne-1-2 i-GPA) ithetha ukungcungcutheka okukhulu kunokwenzeka kwiindawo ezinamachaphaza amakhulu okanye uxinzelelo oluphezulu, kunyanzelisa uhlengahlengiso loyilo olunyusiweyo.
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) okanye ukuvezwa kwe-UV ixesha elide kunokubangela ukuqhekeka kwe-molecular, okukhokelela ekugulekeni (kubonakaliswe njengokuqhuma kunye nokuthetha). Ke ngoko, izicelo zangaphandle zifuna ukongezwa kwee-UV zothintelo okanye iingubo zomphezulu zokhuseleko.
2. I-Logic yoKwakha i-Logic: Ukulinganisa imisebenzi yokusebenza kunye neendlela zokusilela
Uyilo oluthile lwephepha le-PP kufuneka lugxile kumsebenzi "ocetywayo" kunye "neendlela zokusilela ezinokubakho." Iimfuno zomsebenzi eziqhelekileyo ziquka umthwalo -} ukutywina, ukutywina, ukuhlola, okanye ukulungisa imeko-moya, okanye ukwenziwa, i-sporasions, okanye i-scorictions, okanye i-SCORCHION CROORK (ESC).
I-1.
Xa amaphepha e-PP asetyenziswa ekutsaleleni Ngokwemigangatho yendlela yezinto eziphathekayo, elona xabiso lixhaswe ngumthwalo oxhaswayo nge-δ=5 q⁴ / (i-qldi) (i-q yindawo ye-intshi, kwaye ndingumzuzu wecandelo). Ngenxa yexabiso le-EP eliphantsi leephaneli ze-PP, ukuba isakhiwo seplate yeflethi sisetyenziswa ngokuthe ngqo, ukungqubana phantsi kwendawo ezinde kakhulu kuya kudlula kakhulu kwintsebenzo efunekayo (ngokuqhelekileyo, ukungalingani okusebenzayo kungaphantsi okanye ukulingana no-1/200). Izisombululo ziquka:
• Ukonyusa ubunzima: kukuphindaphinda konke ukuphindaphinda, ndilixabisile ukunyuka ngamaxesha ama-8 (i=}}}} i-} icandelo), kodwa oku kukwandisa indleko kunye nobunzima.
• Ukuqiniswa kokuqiniswa okuMpashiweyo: Ngokucinezela i-ribecudiyol / i-ribs eguqukayo (1/2-2 / i-3 yobukhulu bepaneli) ngasemva okanye ilingane ne-3% ye-InEtia, ngelixa kuncitshiswa ukusetyenziswa kwezinto.
• Ukunyanzeliswa kokuqiniswa: Ukudibanisa kunye neefilitha ezifana ne-fiber yeglasi (GF) kunye neCalcium Carbonate (CACCO₃), okanye i-Geco₃) kumphezulu, ezi zixhobo ze-aluminiy zinokuphucula ubungqola.
I-2. Ukutyhubela kunye nonxibelelwano: Ukulungelelanisa unxibelelwano
Iiphaneli ze-PP ziqhele ukusetyenziswa kwizicelo ezinje ngemibhobho yokutywina nebhokisi. Uyilo lwabo lonxibelelwano kufuneka lubhekise kwinqaku lentlungu yokubiwa kwezinto zepolymer. I-Polypropylene inamandla aphantsi komhlaba (malunga ne-30 mn / m), yenza ukuba kube nzima ukwenza iqhina elisebenzayo kunye nabadlali abaqhelekileyo (njenge-epoxy rester). Ke ngoko, iindlela zokungena ngokwasemzimbeni zikhethwa koluyilo:
• Ishushu - inyibilike i-welding: ukusebenzisa inqaku le-PP (malunga ne-160 {2} - {Amaza aphezulu)
• Ikliphu / i-bolt eqinisayo: Uyilo lwe-barches pricces, okanye ukhuselekile ngaphambili
• Ukutywina - ukuncediswa: Ukuba i-adhend yokuthetha iyimfuneko, khetha i-Arhente yoNyango loNyango lwe-PP (isebenzisa i-Arrylive Comment), okanye isebenzise i-acrylive odheved) ukuzalisa umsantsa.
3. Uyilo lokusingqongileyo lokusingqongileyo: I-Anti-
Kwimimandla ekhethekileyo (njengokuphuma, -}} sumaids, kunye neendawo ezine-oxiding kakhulu), uyilo lwephepha le-PP ifuna ukuba kuthathelwe ingqalelo eyongezelelweyo:
I-UV - uyilo olunganyangekiyo: Yongeza i-carbon emnyama (malunga ne-2%) okanye i-on-rays, i-on-rays, i-on-rays, i-on-rays, i-on-rays ye-ondool kunye ne-on-rays ye-Outoors ukusuka kwiminyaka emi-5 ukuya kwiminyaka engaphezu kwe-5.
• Yilo lokuyila / uyilo lwe-antistratic: ukongeza i-carbon emnyama (5% -10%), i-carbon natger, okanye i-powder ye-PP (efana ne-Ale-10⁶ω) okanye ngaphantsi kwe-10³ωm (ibanga). Ifaneleke kwi-Elecriest Acceriers kunye ne-antisttic umgangatho kwizikhululo zegesi.
• Antibacterial Design: Loading silver ions, zinc ions, or nano-titanium dioxide (TiO₂) inhibits bacterial growth through photocatalysis or ion release (antibacterial rate >Iipesenti ezingama-90). Iqhelekile isetyenziswa kwii-countertops zokutya kunye nefowuni yezonyango.
3. Ukulungisa itekhnoloji yeTekhnoloji yeTekhnoloji
Uyilo lwephepha le-PP kufuneka luhlengahlengise kwiimpawu zalo zokulungisa. Izinto zeTRMOPIC zingenziwa ngeendlela ezinje ngenaliti, ukupheliswa, kunye nokucinezelwa kweshushu, kodwa iinkqubo ezahlukeneyo zinika ukusilela okuthile kwiinkcukacha ezithile. Umzekelo:
• Ubungqingqngqwa bokutyhila Ukuba uyilo lufuna ukuchaneka okuphezulu (umz.
Ikona yokujikeleza kunye nokuyila i-Angle: Iikona ezibukhali (i-R <0.5mm) kwinaliti - - -} i-PPS ityekele ekuxinzelelekeni kunye nokuqhekeka. Ke ngoko, zonke iikona kwiyilo kufuneka ijikelezwe (inkulu kune okanye ilingane ne-1mm kuyacetyiswa). Ngaphaya koko, ukuba isibini siqhubekile (umz.
• Ukuhambelana Ngaphandle koko, indawo enqamlezileyo iya kunyibilika kwaye ihambe kuqala ngexesha lokunyibilika eshushu, enokubakho ukuthintela indawo emnandi ekuhlanganiseni.
ISIQINISEKISO: Imephu yesayensi evela kwithiyori yokuziqhelanisa
Uyilo lweephaneli ze-PP ngokwesithathu {{0}- ilungelelene "kwiipropathi ezibonakalayo, iimfuno zomsebenzi, kunye nokulungisa iingxaki." Abaqulunqi kufuneka baqonde ngokunzulu imolekyuli yePolyProplene (enjengempembelelo ye-crystallity), imithetho ye-fight ye-fiblet (njengokusebenza kwe-fight radius) ukufezekisa intsebenzo. Ukuqhubela phambili kubuchwepheshe bokuguqula (njengokuphuhliswa kwe-Nanocoms kunye nophuhliso lwe-bio -} I-POLYPOPLELEne), imigaqo-nkqubo yoyilo ye-PP iya kuqhubeka ivela, ibonelela ngezisombululo ezibonakalayo zoluhlu olubanzi lwezicelo eziphezulu kunye nezicelo ezisebenzayo.
