Nekuda kweplasticization yemagetsi, zvikamu zvemota, uye zvikamu zvemotokari, zvinodiwa zvepamusoro zvinoiswa pakuita naironi uye kupisa kwakanyanya.Izvi zvakavhura nhanganyaya yekutsvagisa nekusimudzira nekushandiswa kwenaironi yepamusoro-soro.
Yakakwira-inoyerera girazi faibha yakasimbiswa yakakwira-tembiricha nylon PPA ndeimwe yemhando nyowani yakwezva kutarisisa, uye zvakare ndeimwe yezvino kukurumidza kukura uye zvinodhura zvakanyanya zvinhu zvitsva.Iyo girazi faibha yakasimbisa tembiricha yakakwira nylon composite zvinhu zvichibva pane yakanyanya tembiricha nylon PPA iri nyore kugadzira yakanyanya kurongeka, yakakwirira tembiricha inodzivirira uye yakakwirira simba zvigadzirwa.Kunyanya kune enjini yemotokari zvigadzirwa, izvo zvinoda kutarisana nekuwedzera kuomesesa kuchembera zvinodiwa, yakakwirira-tembiricha nylon zvishoma nezvishoma yave sarudzo yakanakisa yemotokari enjini yemidziyo.Chiiuniquepamusoro pekushisa kwenylon?
1, Yakanakisa mechanical simba
Kuenzaniswa neyechinyakare aliphatic nylon (PA6/PA66), tembiricha yakakwira naironi ine mabhenefiti ari pachena, ayo anonyanya kuratidzwa mune ekutanga machira echigadzirwa uye nekupisa kwayo.Kuenzaniswa nesimba rekutanga remuchina, tembiricha yakakwira nylon ine yakafanana girazi fiber zvirimo panzvimbo.Iyo 20% yakakwira kupfuura yechinyakare aliphatic nylon, iyo inogona kupa mamwe marepu emhinduro kumotokari.
Automotive thermostatic housing yakagadzirwa nepamusoro tembiricha nylon.
2, Ultra-yakanyanya kupisa kuchembera kuita
Pasi peiyo tembiricha yekupisa deformation ye1.82MPa, tembiricha yakakwira naironi 30% girazi faibha yakasimbiswa inogona kusvika 280 ° C, nepo yechinyakare aliphatic PA66 30% GF ingangoita 255 ° C.Kana izvo zvinodikanwa zvechigadzirwa zvichiwedzera kusvika pa200 ° C, zvinonetsa kune echinyakare aliphatic nylons kuti asangane nezvinodiwa zvechigadzirwa, kunyanya ejini zvigadzirwa zvepamhepo zvave mukupisa kwakanyanya uye kupisa kwakanyanya kwenguva yakareba.Munzvimbo yakanyorova, uye inofanirwa kumira nekuora kwemafuta emagetsi.
3, Yakanakisa dimensional kugadzikana
Mwero wekunyudzwa kwemvura wealiphatic nylon wakakwira zvakanyanya, uye mwero wemvura wakazara unogona kusvika pa5%, zvichikonzera kudzikama kwakadzika kwechigadzirwa, izvo zvisina kukodzera kune zvimwe zvigadzirwa zvemhando yepamusoro.Huwandu hwemapoka emaamide mukupisa kwepamusoro nylon hwakadzikiswa, mwero wekunyudzwa kwemvura zvakare hafu yeyakajairika aliphatic nylon, uye kugadzikana kwedimensional kuri nani.
4, Yakanakisa makemikari kuramba
Sezvo zvigadzirwa zvepamhepo zveinjini dzemotokari zvinowanzo sangana nemakemikari, zvinodikanwa zvakakwirira zvinoiswa pamakemikari anopokana nezvinhu, kunyanya kuora kwepeturu, firiji uye mamwe makemikari ane corrosion mhedzisiro paaliphatic polyamide, ukuwo tembiricha yakakosha. chimiro chenylon chinogadzirisa kukanganisa uku, saka kutaridzika kwepamusoro-tembiricha nylon yakasimudza nzvimbo yekushandisa injini kusvika padanho idzva.
Yemotokari humburumbira musoro mavhavha akagadzirwa nepamusoro tembiricha naironi.
Zvishandiso zveindasitiri yemotokari
Sezvo PPA ichigona kupa tembiricha yekuvhiringa kupisa inopfuura 270 ° C, ipurasitiki yeinjiniya yakakodzera yezvikamu zvinodzivirira kupisa mumaindasitiri emotokari, makanika, uye emagetsi / emagetsi.Panguva imwecheteyo, PPA yakanakirawo zvikamu izvo zvinofanirwa kuchengetedza kuvimbika kwechimiro panguva pfupi-yepamusoro tembiricha.
Yemotokari hood yakagadzirwa neiyo yakanyanya kupisa nylon
Panguva imwecheteyo, iyo plasticization yezvikamu zvesimbi senge mafuta masisitimu, masisitimu emhepo, uye inotonhorera masisitimu padyo nejini yakatsiviwa ne thermosetting resins yekudzokorodza, uye zvinodiwa zvezvinhu zvakanyanya kuomarara.Kuramba kupisa, kusimba, uye kuramba kwemakemikari ekare-chinangwa einjiniya mapurasitiki haachakwanise kuzadzisa zvinodiwa.
Uye zvakare, iyo yakanyanya tembiricha nylon inoteedzana inochengetedza zvinozivikanwa zvakanakira zvepurasitiki, zvinoti nyore kugadzirisa, kucheka, kusununguka kwemahara dhizaini yeakaomesesa anoshanda akabatanidzwa zvikamu, uye kuderedzwa uremu uye ruzha uye marara kuramba.
Sezvo tembiricha yakakwira nylon inogona kumira nesimba rakakwirira, tembiricha yakakwira uye dzimwe nzvimbo dzakaomarara, yakanyatsokodzera enzvimbo dzejini (zvakadai semavhavha einjini, ma switch uye zvibatanidza) uye masisitimu ekutapurirana (seakatakura makeji), masisitimu emhepo (senge exhaust air control system) uye midziyo yekupinza mhepo.
Zvakadaro, iwo akanakisa zvivakwa zvetembiricha yakakwira nylon inogona kuunza akawanda mabhenefiti kune vashandisi, uye kana uchitendeuka kubva kuPA6, PA66 kana PET/PBT zvinhu kuenda kuPPA, hapana chikonzero chekugadzirisa mold, nezvimwe, saka yakakodzera kune akasiyana maapplication. inoda kupikisa kwekushisa kwepamusoro.Pane tarisiro huru.
