Ngenxa yepulasitiki yezingxenye ze-elekthronikhi, izimoto, nezingxenye zezimoto, izidingo eziphakeme zibekwe ekusebenzeni kwe-nylon kanye nokumelana okushisa okuphezulu. Lokhu kwavula isethulo esicwaningini nasekuthuthukisweni nasekusetshenzisweni kwe-nylon yokushisa ephezulu.
I-High-Flow Glass Fingy FixECed Inalon PPA ingenye yezinhlobo ezintsha ezidonsele ukunakwa kakhulu, futhi futhi kungenye yezinto ezintsha ezikhula ngokushesha nezingabizi kakhulu. I-fiber yengilazi iqinisile izinto eziphakeme zokushisa zenayini zenalon ze-nylon ezisuselwa ekushiseni okuphezulu kwe-nylon PPA kulula ukukhiqiza ukunemba okuphezulu, imikhiqizo ephezulu yokumelana nemikhawulo ephezulu. Ikakhulu kwimikhiqizo ye-temotive injini ye-peripheral, edinga ukubhekana nezidingo zokuguga ezikhulayo, i-nylon yokushisa ephezulu iye yaba ukukhetha okungcono kakhulu kwezinto ezihlanzekile zezimoto. Yini-hlukilemayelana nokushisa okuphezulu kwe-nylon?
1, amandla amahle emishini
Uma kuqhathaniswa ne-Aliphatic Nylon (PA6 / PA66) Uma kuqhathaniswa namandla ayisisekelo emishini, i-NYLON yokushisa ephezulu inokuqukethwe okufanayo kwe-fiber yengilazi esibonelweni. Kuphezulu kwama-20% kune-Aliphatic Nylon yendabuko, enganikeza ngezixazululo ezingasindi kwezimoto.

2, ukusebenza kwe-Ultra-High Heat Age Creaty
Ngaphansi kwesisekelo sokushisa okushisayo okushisayo kwe-1.82MPA yokushisa kwe-1.8mpla, izinga lokushisa eliphakeme le-nylon 30% liqinisile lingafinyelela ngo-280 ° C. 30% GF acishe abe ngu-255 ° CF acishe abe ngu-255 Lapho izidingo zomkhiqizo zikhuphuka zifinyelela ku-200 ° C, kunzima kuma-allons endabuko avumelanayo ukuze ahlangabezane nezidingo zomkhiqizo, ikakhulukazi imikhiqizo ye-enjini evuthayo ibisezingeni eliphakeme kakhulu kanye nokushisa okuphezulu isikhathi eside. Emvelweni emanzi, futhi kufanele kubekezelele ukubhujiswa kwamafutha emishini.
3, ukuzinza okuhle kakhulu kobukhulu
Izinga lokufakwa kwamanzi kwe-aliphatic nylon liphezulu kakhulu, futhi isilinganiso sokugcotshwa kwamanzi sifinyelela ku-5%, okuholela ekuzinzeni okuphansi kakhulu komkhiqizo, okungafaneleki kakhulu eminye imikhiqizo ephezulu. Ingxenye yamaqembu amide e-High Temperature nylon iyancishiswa, izinga lokufakwa kwamanzi libuye libe yingxenye yalokho kwe-aliphatic nylon ejwayelekile, futhi ukuqina kobukhulu kungcono.
4, ukumelana okuhle kwamakhemikhali
Njengoba imikhiqizo ye-peripheral yezinjini zezimoto ivame ukuxhumana nabantu abasebenza ngamakhemikhali, ikakhulukazi izidingo zamakhemikhali zokwenziwa kophethiloli, okuqandayo namanye amakhemikhali kunomthelela obonakalayo we-polyamide, ngenkathi izinga lokushisa eliphakeme Ukwakheka kwe-nylon kwenzelwa lokhu kwashifu, ngakho-ke ukubukeka kwe-nylon ephezulu kakhulu kuphakamise indawo yokusebenzisa yenjini kuya ezingeni elisha.

Izicelo zemboni yezimoto
Njengoba i-PPA inganikeza ukushisa kokushisa kokushisa okungaphezu kwama-270 ° C, kuyinto elungele ubunjiniyela bobunjiniyela bezingxenye ezivimbela ukushisa ezithunzini, emishini, kanye nezimboni zikagesi / zikagesi. Ngasikhathi sinye, i-PPA nayo ilungele izingxenye ezizogcina ubuqotho bezinhlekelele emazingeni okushisa aphezulu wesikhathi esifushane.
I-Automotive Hood eyenziwe nge-Nylon yokushisa ephezulu
Ngasikhathi sinye, ukuhanjiswa kwepulasitiki kwezindawo zensimbi ezifana nezinhlelo zikawoyela, izinhlelo zokuphelelwa amandla, nezinhlelo zokupholisa eduze kwenjini zithathelwe indawo yi-thermosetting resins yokuphinda usebenzise kabusha, futhi izidingo zezinto zokwakha ziqinile. Ukumelana nokushisa, ukuqina, kanye nokumelana kwamakhemikhali kwe-plastistics yobunjiniyela obujwayelekile obujwayelekile abasakwazi ukufeza izidingo.
Ngaphezu kwalokho, uchungechunge lwamazinga okushisa aphezulu lugcina izinzuzo ezaziwayo zamapulasitiki, okungukuthi kube lula ukucubungula, ukunqunywa, ukukhululeka kwamahhala kwezingxenye eziyinkimbinkimbi ezihlanganisiwe, kanye nokuphika kwesisindo nomsindo nokugqwayiza.
Njengoba amazinga okushisa aphezulu angamelana namandla aphezulu, izinga lokushisa eliphakeme nezinye izindawo ezinokhahlo, lilungele kakhulu i-eIzindawo ze-NG (ezifana nezinjini zenjini, ukushintshwa kanye nezixhumi zezinhlelo) nezinhlelo zokuhambisa) nezinhlelo zomoya (ezinjengezinhlelo zokulawula umoya) namadivayisi wokulawula umoya.
Noma kunjalo, izakhiwo ezinhle kakhulu ze-high freet nylon zingaletha izinzuzo eziningi kubasebenzisi, futhi lapho ziguqulwa kusuka ku-PPA6, PA66 noma izilwane zasekhaya ziye kwi-PPA, ngokuyisisekelo asikho isidingo sokushintsha isikhunta, njll., Ngakho-ke kufanelekile ukuthola izicelo ezahlukahlukene edinga ukumelana okushisa okuphezulu. Kunamathemba abanzi.
