Izindaba

Emkhakheni wezimoto ohlala ushintsha, amapulasitiki alula abe yinto eshintsha umdlalo. Ngokunikeza isilinganiso esiphezulu samandla nesisindo, ukuguquguquka komklamo, kanye nokusebenza kahle kwezindleko, amapulasitiki alula abalulekile ekubhekaneni nezidingo eziphuthumayo zomkhakha zokusebenzisa kahle uphethiloli, ukunciphisa ukukhishwa komoya, kanye nokusimama. Kodwa-ke, yize lezi zinto ziletha izinzuzo eziningi, ziza nezinselele ezithile. Kulesi sihloko, sizohlola amaphuzu avamile obuhlungu ekusetshenzisweni kwamapulasitiki alula embonini yezimoto futhi sinikeze izixazululo ezisebenzayo ezingathuthukisa ukusebenza futhi zinciphise izindleko zokukhiqiza.

Ziyini Ipulasitiki Ezilula?

Amapulasitiki alula angama-polymer aphansi, njenge-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-acrylonitrile butadiene styrene (ABS), i-polycarbonate (PC), kanye ne-polybutylene terephthalate (PBT), kanti ubuningi busukela ku-0.8–1.5 g/cm³. Ngokungafani nezinsimbi (isb. insimbi: ~7.8 g/cm³), lawa mapulasitiki anciphisa isisindo ngaphandle kokulahlekelwa yizakhiwo ezibalulekile zemishini noma zokushisa. Izinketho ezithuthukisiwe njengepulasitiki ene-foam (isb. i-polystyrene enwetshiwe, i-EPS) kanye nama-composites e-thermoplastic anciphisa ubuningi ngenkathi egcina ubuqotho besakhiwo, okwenza kube kuhle ukusetshenziswa kwezimoto.

Ukusetshenziswa Kwepulasitiki Elula Embonini Yezimoto

Amapulasitiki alula abalulekile ekwakhiweni kwezimoto zesimanje, okwenza abakhiqizi bakwazi ukuhlangabezana nemigomo yokusebenza kahle, ukusebenza kahle, kanye nokusimama. Izinhlelo zokusebenza ezibalulekile zifaka:

1. Izingxenye Zangaphakathi Zezimoto:

Izinto zokwakha: PP, ABS, PC.

Izicelo: Amadeshibhodi, amaphaneli eminyango, izingxenye zezihlalo.

Izinzuzo: Ilula, ihlala isikhathi eside, futhi ingenziwa ngezifiso ukuze ibukeke kahle futhi ikhululeke.

2. Izingxenye Zangaphandle Zezimoto:

Izinto zokwakha: I-PP, i-PBT, i-PC/PBT blends.

Izicelo: Amabhampa, ama-grille, izindlu zesibuko.

Izinzuzo: Ukumelana nokushayisana, ukuqina kwesimo sezulu, kanye nokwehla kwesisindo semoto.

3. Izingxenye Ezingaphansi Kwe-Hood:

Izinto zokwakha: i-PBT, i-polyamide (inayiloni), i-PEEK.

Izicelo: Izembozo zenjini, ama-manifold okungenisa umoya, kanye nezixhumi.

Izinzuzo: Ukumelana nokushisa, ukuqina kwamakhemikhali, kanye nokunemba kobukhulu.

4. Izingxenye Zesakhiwo:

Izinto zokwakha: I-PP noma i-PA eqiniswe ngengilazi noma nge-carbon fiber.

Izicelo: Ukuqinisa i-chassis, amathreyi ebhethri ezimoto zikagesi (ama-EV).

Izinzuzo: Isilinganiso samandla aphezulu nesisindo, ukumelana nokugqwala.

5. Ukuvikela kanye Nokugudla:

Izinto zokwakha: Amagwebu e-PU, i-EPS.

Izicelo: Ama-cushion ezihlalo, amaphaneli okuvikela umsindo.

Izinzuzo: Ukukhanya okukhulu, ukumuncwa kwamandla okuhle kakhulu.

Ezimotweni zikagesi, amapulasitiki alula abaluleke kakhulu, njengoba enciphisa isisindo samabhethri asindayo, andise ibanga lokushayela. Isibonelo, izindlu zamabhethri ezisekelwe ku-PP kanye ne-PC glazing kunciphisa isisindo ngenkathi kugcinwa amazinga okuphepha.

Izinselele Ezivamile Nezixazululo Zepulasitiki Ezilula Ekusetshenzisweni Kwezimoto

Naphezu kwezinzuzo zazo, njengokusebenzisa kahle uphethiloli, ukunciphisa ukukhishwa komoya ongcolile, ukuguquguquka komklamo, ukusebenza kahle kwezindleko, kanye nokusetshenziswa kabusha, amapulasitiki alula abhekene nezinselele ekusetshenzisweni kwezimoto. Ngezansi kunezinkinga ezivamile kanye nezixazululo ezisebenzayo.

Inselele 1:Ukuklwebheka Nokugqokwa Okungazweli Epulasitikini Yezimoto 

Inkinga: Izindawo zepulasitiki ezilula njengePolypropylene (PP) kanye ne-Acrylonitrile Butadiene Styrene (ABS), ezivame ukusetshenziswa ezingxenyeni zezimoto njengamadeshibhodi namaphaneli eminyango, zisengozini yokuklwebheka nokuqhekeka ngokuhamba kwesikhathi. Lokhu kungapheleli kobuso akugcini nje ngokuphazamisa ukubukeka kobuhle kodwa futhi kunganciphisa ukuqina kwesikhathi eside kwezingxenye, okudinga ukulungiswa okwengeziwe nokugcinwa.

Izixazululo:

Ukuze kuxazululwe le nselele, ukufaka izithasiselo ezifana nezithasiselo zepulasitiki ezisekelwe ku-silicone noma i-PTFE ekwakhiweni kwepulasitiki kungathuthukisa kakhulu ukuqina kwendawo. Ngokufaka u-0.5-2% walezi zithasiselo, ukungqubuzana kwendawo kuyancishiswa, okwenza izinto zingabi sengozini yokuklwebheka nokuqhekeka.

Njengoba kunabakhiqizi abaningi bezithako ze-silicone abatholakalayo, yiziphi izindlela okufanele uzisebenzise ukukhetha umlingani webhizinisi ofanele?

KwaChengdu Silike Technology Co., Ltd., sigxile kakhulu ku-izithasiselo zepulasitiki ezisekelwe ku-siliconeYenzelwe ukuthuthukisa izakhiwo ze-Thermoplastics kanye ne-Engineering plastics ezisetshenziswa ezimotweni. Njengoba ineminyaka engaphezu kwengu-20 yesipiliyoni ekuhlanganisweni kwe-silicone nama-polymers, i-SILIKE iqashelwa njengomsunguli ohamba phambili kanye nomlingani othembekile wokusebenza kahle kakhulu.ukucubungula izixazululo zezithasiselo kanye nezilungisi.

Okwethuizithasiselo zepulasitiki ezisekelwe ku-siliconeimikhiqizo yenzelwe ngqo ukusiza abakhiqizi be-polymer:

1) Thuthukisa amazinga okukhipha futhi ufeze ukugcwaliswa kwesikhunta okuhambisanayo.

2) Thuthukisa ikhwalithi kanye nokuthamba kobuso, okufaka isandla ekukhululweni kwesikhunta okungcono ngesikhathi sokukhiqiza.

3) Ukunciphisa ukusetshenziswa kwamandla nokunciphisa izindleko zamandla ngaphandle kokudinga ukuguqulwa kwemishini yokucubungula ekhona.

4) Izithasiselo zethu ze-silicone zihambisana kakhulu nohlu olubanzi lwe-thermoplastics kanye nepulasitiki yobunjiniyela, okuhlanganisa:

I-Polypropylene (PP), i-Polyethylene (HDPE, LLDPE/LDPE), i-Polyvinyl Chloride (PVC), i-Polycarbonate (PC), i-Acrylonitrile Butadiene Styrene (ABS), i-Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS), i-Polystyrene (PS/HIPS), i-Polyethylene Terephthalate (PET), i-Polybutylene Terephthalate (PBT), i-Polymethyl Methacrylate (PMMA), i-Nylon (Polyamides, PA), i-Ethylene Vinyl Acetate (EVA), i-Thermoplastic Polyurethane (TPU), i-Thermoplastic Elastomers (TPE), nokuningi.

Lokhuizithasiselo ze-siloxanefuthi kusiza ekuqhubekiseleni phambili imizamo eya emnothweni ojikelezayo, ukusekela abakhiqizi ekukhiqizeni izingxenye ezisimeme nezisezingeni eliphezulu ezihlangabezana nezindinganiso zemvelo.

I-SILIKE Silicone Wax I-SILIMER 5235: Indlela Entsha Yokuthuthukisa Ubuso Bokumelana Nokuklwebheka Okuthuthukisiwe

Ngale kwejwayelekileizithasiselo zepulasitiki ezisekelwe ku-silicone, SILIMER 5235, ii-silicone wax eguqulwe nge-alkyl,Ivelele. Iklanyelwe ngqo imikhiqizo yepulasitiki elula kakhulu njenge-PC, i-PBT, i-PET, kanye ne-PC/ABS, i-SILIMER 5235 inikeza ukumelana okuhle kakhulu kokuklwebheka nokuguguleka. Ngokuthuthukisa ukugcotshwa kwendawo kanye nokuthuthukisa ukukhululwa kwesikhunta ngesikhathi sokucubungula, kusiza ukugcina ukuthungwa nokukhanya kwendawo yomkhiqizo ngokuhamba kwesikhathi.

Enye yezinzuzo ezibalulekile ze-i-silicone waxI-SILIMER 5235 ihambisana kahle kakhulu nama-resin ahlukahlukene e-matrix, okuqinisekisa ukuthi akukho mvula noma umthelela ekuphathweni komhlaba. Lokhu kuyenza ifaneleke kakhulu ezingxenyeni zangaphakathi zezimoto lapho kokubili ikhwalithi yobuhle kanye nokuqina kwesikhathi eside kubalulekile.

Inselele 2: Amaphutha Okungaphezulu Ngesikhathi Sokucubungula

Inkinga: Izingxenye ezibunjwe ngomjovo (isb., amabhampa e-PBT) zingase zibonise ama-splay, imigqa yokugeleza, noma izimpawu zokusinki.

Izixazululo:

Omisa ama-pellets kahle (isb., 120°C amahora angu-2-4 ukuze uthole i-PBT) ukuvimbela ukusabalala okuhlobene nomswakama.

Lungiselela isivinini somjovo kanye nokucindezela kokupakisha ukuze ususe imigqa yokugeleza kanye namamaki okusinki.

Sebenzisa izikhunta ezipholishiwe noma ezithambile ezinezimbobo zomoya ezifanele ukunciphisa amamaki okusha.

Inselele 3: Ukumelana Nokushisa Okulinganiselwe

Inkinga: I-PP noma i-PE ingase iguge ngaphansi kwamazinga okushisa aphezulu ekusetshenzisweni okungaphansi kwe-hood.

Izixazululo:

Sebenzisa amapulasitiki angashisi njenge-PBT (indawo yokuncibilika: ~220°C) noma i-PEEK ezindaweni ezinokushisa okuphezulu.

Faka imicu yengilazi ukuze uthuthukise ukuzinza kokushisa.

Faka izembozo zokuvimbela ukushisa ukuze uthole isivikelo esengeziwe.

Inselele 3: Ukulinganiselwa Kwamandla Emishini

Inkinga: Amapulasitiki alula angase angabi nokuqina noma ukumelana nokushayisana kwezinsimbi ezingxenyeni zesakhiwo.

Izixazululo:

Qinisa ngemicu yengilazi noma yekhabhoni (10–30%) ukuze uqinise amandla.

Sebenzisa izinhlanganisela ze-thermoplastic zezingxenye ezithwala umthwalo.

Yakha izingxenye ezinezimbambo noma izingxenye ezingenalutho ukuze uthuthukise ukuqina ngaphandle kokwengeza isisindo.
