General Injiniya Purasitiki: Polycarbonate PC, Polyyoxymymyly pom, polyamide pa, Thermoplastic Pom, Thermoplastic Polyster PBT / Pet, Yakagadziriswa Polyphenylene Ethers Mppo.

Ndeipi nzvimbo yekutanga yemuviri yechinhu chimwe nechimwe?

1. Polyamide: (zita rakajairika: Nylon, PA, PA6, PA6, PA610, PA1010, nezvimwewo).

PA6: Polycapuristack. Pa66: polyhexamleediamine dengire.

Zvakanakira:

Yakadzika chaizvo Gravity (chete 1/7 yesimbi), "nyoro uye nyoro" inogona kuongororwa mune zvakashata zvigadzirwa panzvimbo yesimbi.

Kupisa kupokana, mafuta, kuchera, kuzvishongedza

Simba rakakwirira kwazvo, rakanakisa kukanganiswa, kusimbisa kwemagetsi;

Gasi rinotsungirira zvivakwa, zviri nani kuvhara oksijeni.

Zvinokuvadza:

Iyo inodzikira chiyero chakakura uye chakazara kugadzikana kune varombo.

Kukwirisa kwemvura kwakanyanya, zviri nyore kutora unyoro, kuwedzera muhukuru, (hydrolysis).

Nyore kune oxidize uye yero (pyrolysis).

Kufananidza kuongorora:

Kukanganisa kuramba, solubility kuramba, kudzima kwemvura (zvisina kunaka): PA6> PA66

Pfeka kupokana, kupisa kupisa (kupisa kukanganisa kwekushisa), kuimbira pfungwa: PA6. Naizvozvo, mutengo wemusika pa66 wakakwira kupfuura pa6.

Kuoma: PA66

Chaizvoizvo application:

Pombi impeler, fan blades, chigaro cheValve, bushings, fani, zviridzwa zvemagetsi zvemagetsi, zviridzwa zvemotokari zvinopisa uye zvinotonhora uye zvimwe zvinhu. About 3.6 kusvika 4 kilogiramu yeNylon zvigadzirwa zvinodyiwa pamotokari. Polyamide ine iyo hombe hurukurowa chiyero muindasitiri yemotokari, nemagetsi nemagetsi.

2. Polycarbonate (PC):

Zvakanakira:

Optical grade transpency yakakwira, uye inogona kuve yakajeka yemavara.

Simba rekukanganisa rakanyanya kukwirira uye rinogona kusaparadzwa nekumanikidza.

Kukwegura kupokana (makore maviri).

Kudzivirira moto, kuora kunogadzira CO2 murazvo unodzoreredza, kuzvidzima.

Kupisa kupesana, kusimbisa kwemagetsi kwakanaka.

Yakadzika shrinkage, yakakwira dimensional kugadzikana, yakaderera warpage.

Ine simba rimwe chete setsetse dzisiri dzisina simba, asi zvakare ine miviri inoshaka nekuoma. Inogona kutsungirira kuputika kwe tv skrini.

Zvinokuvadza:

Izvo zvinowanzoitika kunetseka kwemukati kupaza.

Varombo vanopfeka kurwisa.

Inonzwira tsitsi kune iyo gomba.

Solar Solvent kuramba (Alkali), tembiricha yakakwira iri nyore kuHydrolyze.

Kuramba kusaremekedza kuramba.

Kuomarara pamusoro.

Kuwirirana kusingaenzaniswi nemamwe anoona.

Friction coefficient yakakura, isina kuzvisimbisa.

Kufananidza kuongorora:

Creep Kuramba: PC> (PA uye POM Series Zvigadzirwa)

Mutengo wemusika uri pakati nepakati.

Chaizvoizvo application:

Kuchengetedza marambi, magetsi ekudzivirira, magetsi ekudzivirira nhandare yezvinetso, girazi rakatsemuka, magirazi emotokari, mhepo yemhepo, girazi remotokari, mudhudhudhu, mudhudhudhu dhaya rinorira. Misika inonyanya kushandiswa makomputa, zvigadzirwa zvehofisi, mota, mamwe magirazi nemashiti, uye CD uye DVD discs ndeyemakero anovimbisa zvakanyanya.

3. Polyoxymethylene (POM):

Zvakanakira:

Pfeka kupokana kwakanaka. Zvakafanana nekuomarara, simba uye kuomarara kwesimbi.

Simba rekukanganisa rakakwira.

Kusimbisa kwemagetsi kuri nani.

Yakaderera mvura yekukwenenzvera, yakanakisa dimensional kugadzikana. (hapana chikonzero chekuoma)

Iyo muganho PV kukosha kwakakura uye kuzvirongedza pachako zvinhu zvakanaka.

Kuomarara uye kusakara kwakanaka. Kuneta kwakanaka kuramba.

Zvinokuvadza:

Kushomeka kwemamiriro ekunze kurwisa, nyore kuupfu, kupaza.

Density yakakura (1.42).

Inotaridzika kwazvo negeji.

Murombo solvent kuramba (acid).

Kuumbwa kwakaderera kuwanda kwakakura.

Yakakwira tembiricha yekudzora yakasimba murombo, kuora kweiyo odya foror formaldehyde.

Kufananidza kuongorora:

Impact Simba: (PC uye AT SECE SECEPS MABHUKU)> POM

Pfeka Rwisa: POM> PA6> PA6> ABS> HPVC> PS> PC

Mutengo wemusika pom zvine mwero.

Chaizvoizvo application:

Magetsi uye zvemagetsi, michina, chishandiso, chishandiso chezuva nezuva indasitiri, motokari, zvekuvakisa, kurima uye mamwe minda. Zvikumbiro muminda yakawanda matsva, tekinoroji yekurapa, mitambo yemitambo.

4. PolyTyley terephthalate (PBT) uye polyethylene terephthalate (pet)

PBT:

Zvakanakira:

Kurumidza kuchema, kukurumidza kuratidzira, kupfupi kwekugadzirisa kutenderera. .

Pfeka kuramba, kuramba kwemamiriro ekunze kwakanaka.

Kusimbisa kwemagetsi kuri nani.

Kubata kuomarara kwakanaka.

Zvinokuvadza:

Inotaridzika kwazvo negeji.

PBT inofanirwa kuomeswa pa 110 ~ 120 ° C kweanenge maawa matatu usati jekiseni kuumbwa. Iko kuumbwa kwekugadzirisa tembiricha ndeye 250-270 ° C, uye tembiricha yakaumbwa inodzorwa pa50-75 c.

PBT iri nyore kuora kana yemvura (shandisa chenjedzo mukupisa kwakanyanya uye yakakwirira yekunyoroveswa nzvimbo).

Kufananidza kuongorora:

TG: Pet (75 ° C)> PBT (40 ° C)

Pfeka huwandu: pom> pbt

Melting Point: Pet> PBT

Kupisa Kupokana: Pet> PBT

Pfeka Rwisa: Pet

PET ine tembiricha yakakwira, chiyero chinononoka chengarava, tembiricha yakakwira mujekiseni yekuumba, uye kutenderera kwakareba kwekuumbwa kunogumira. Mutengo wemusika PBT iri pakati nepakati.

Chaizvoizvo application:

Mumagetsi, maisitiri yemagetsi uye emagetsi emagetsi. Nekuda kwekusimbisa kwepamusoro uye kupisa kwePBT, inogona kushandiswa seyekudziyisa tV Zvishandiso zvigunwe.

5. Polyphenylene ether Ppo / PPPE:

PPO:

Zvakanakira:

Yakaderera shrinkage, kudzikisira kudzikama.

Yakakura tembiricha yakasviba (-127 ~ 121 ° C). Kuzvidzima uye kuzvidzivirira-kuzvidzima zvinhu zve nylon zvinoreva, asi nzvimbo yekuzvidzivirira-yekuzvidzivirira ndeyekudzima zviri nani.

Density 1.06 "iyo yakaderera engineering mapurasitiki".

Pfeka kupokana, kupikisa kwemvura, kupikisa simba. Yakanaka acid naAlkali kuramba.

Simba resimba, impact simba, kupokana nekukanda.

Yakasarudzika yemagetsi insulation dielectric nzvimbo "yekutanga yeinjiniya mapurasitiki.

Zvinokuvadza:

Kuyerera kunoyerera murombo.

Kudzivirira kusarongeka kune organic sol sol sol.

Kusarongeka kwechiedza kuramba.

Kufananidza kuongorora:

Density: Pom> PBT> PC> PA> PPO.

Chaizvoizvo application:

Panzvimbo pesimbi isina tsvina, zviridzwa zvekuratidzira zvekurapa zvinogadzirwa. Muindasitiri yemagetsi, magiya, blower blades, mapaipi, macves, zvidimbu uye mamwe matsotsi uye anounganidza uye anobatana anogona kuitwa. Ivo zvakare vanoshandiswawo kuita zvikamu mumagetsi nemagetsi magetsi, senge coil mablabins uye mapuranga akadhindwa ematunhu.
