Zvivakwa zve nylon (PA) zvinhu

Nhanganyaya kuna Nylon

Nylon (nylon, polyamide, pa kwenguva pfupi) zvinoreva mapurasitiki anoumbwa nePolyamide resins. Nzvimbo dzakadaro dzinogona kugadzirwa nePolycendenation ye dicarboines uye dicarboxyylic acids, kana nekuvhenekera-kuvhura polymerization yeamino acids yakaumbwa mushure mekushayikwa kwemvura. Kusiyana nePS, PE, PP, etc., PA haina kupfava zvishoma nezvishoma nekuwedzera kwekushisa tembiricha, iyo inoshambidzwa nzvimbo yekunyungudika, iyo inotaurwa zvikuru, uye yekunyungudika ndeye 215-225 ° C. Kana tembiricha ichinge yasvika, inoita kunge inoyerera. Kuyerera kunoitika kamwe kupisa kwasvika.

Kune akawanda akasiyana eA, kunyanya PA6, PA6, PA610, PA11, PA12, PA1010, PA2T, MXT - 6 PA6, PA66, PA610, PA11, PA12 ndiyo inonyanya kushandiswa.

NYLON Enganisheni Plastics inoburitswa mukuonekwa kweNyar, yakaoma, yakajeka, chena (kana Milky White) kana yerovhu, pachena kana Translucent Crystalline resin, zviri nyore kunyorwa mune chero ruvara. Zviyero zvinyoro-nyoro zve nylons seinjiniya mapurasitiki zvinowanzoitika 15-30 zviuru. Denes dzadzo dzakakura kupfuura 1, density: 1.14-1.15g / cm3. Simba reSimba:> 60.0mpa. Kugutsikana:> 30%. Simba rinoslipera: 90.0 MPA. Kukotama Simba: 90.0 MPA. Asina kuchenjera kukanganisa simba:

Dimensional shanduko nekuda kwekunyorova kwekunyorova mushure mekuumbwa kunofanirwa kucherechedzwa. Mvura inobata 100% 8% kana ikazadzwa neyemukurukurira zvine hungwaru. Kupisa tembiricha: -40 ~ 105 ° C. Inline Pfungwa: 215 ~ 22 ° C. Inline Pfungwa: 215 ~ 225 ℃. Yakakodzera Wall Bickness 2 ~ 3.5mm. Pa mechancal Properties yakadai seyakafanana uye ine simba nekushambadzira uye kushanduka, saka mvura ine simba, kugona kutsungirira tembiricha zvakare yakawedzera. . Kana iwe uchida kuwana yakakosha lubrication mhedzisiro, iwe unogona kuwedzera sulfide muPA.

Zvakanakisa zvakanakira pa performance

1. Simba rakakwirira rekusimba, kunyima kwakanaka, yakakwirira yeiyo tonile uye ine simba rekumanikidza. Kupfuura simba resimba rakakwira kupfuura simbi, kupfuura simba rekumanikidza uye simbi haina kufanana, asi haina kuomarara simbi. Simba rakajeka riri padyo nekubereka simba, kanopfuura kaviri pakakwirira seABS. Chikanganiso, kushushikana vibration kugona, kukanganisa simba kwakanyanya kupfuura iyo general plastiki, uye iri nani pane acetal resin.

. Zvakajairika Escalator Handrails, New Purasitle Bhasiketi Rims uye mamwe eCyclical Frigue basa inguva dziri pachena dzinowanzoisa pa.

3. Yakakwirira yekunyorova pfungwa, kupisa-kupokana (kwakadai seNylon 46, inogona kushandiswa kwenguva yakareba kusvika pamadhigirii akasimbiswa degrees celsius).

4. Smooth pasi, diki diki yekukakavara, kupfeka-kupora. Zvekuita kwezviitiko zvechisimbiso, kuzvishingisa, ruzha rwekuzvifunga, mune chikamu chekupokana hachina kunyanya kukwirira kana chisingakwanise kuwedzera lubriants kuti vashandise. Kana iwe uchinyatsoda kushandisa lubriants kuti uderedze kupokana kana kubatsira kupisa kupisa, ipapo mafuta emvura, mafuta uye zvakadaro pane anogona kusarudzwa. Saka, ine hupenyu hwakareba hwebasa sechikamu chekutapurirana. 5.

5. Kuramba kweCorrosance, kupokana kwazvo kuAlkali uye kwakanyanya mhinduro, asi zvakare kupokana nemafuta, kurwisa manomita, Izvo zvinodzivirira peturu, mafuta, mafuta, doro, asina simba Alkali, etc. uye ane kugona kwakanaka kweanti-a anti-aging. Inogona kushandiswa seyakagadzirwa zvigadzirwa zve lubricants, mafuta, nezvimwe.

.

7. Zvakanakisa zvemagetsi zvemagetsi. Misangano yakanaka kwazvo yemagetsi, nylon vhoriyamu kuramba kwakanyanya, kuputsa kwakanyanya, munzvimbo yakaoma, inogona kushandiswa kuwanda kwekusimbisa, kunyangwe munzvimbo yakakwirira yekuzvininipisa ichine magetsi akanaka emagetsi.

8. Kurema uremu, nyore kune dhayi, nyore kuumbwa. Nekuda kwekudzima melt viscossity, inogona kuyerera nekukurumidza. Zviri nyore kuzadza chiumbwa, ichizadza iyo fold mushure mekusimbisa nzvimbo yakakwira, inogona kukurumidza kuumbwa, saka kutenderera kwekunyura kwepfupi, kunyatsogadzira.

Izvo zvakashata zvakashata zve PA Properties

1. nyore kutora mvura. Mvura inobata, mvura yakazara inogona kusvika inopfuura 3%. Kune imwe nhanho inokanganisa kugadzikana kwemukati uye zvivakwa zvemagetsi, kunyanya zvakatetepa-zvikamu zvakakora zvekuita zvakakura zvekuchinja kukuru; Mvura yekurumwa ichadzikisawo zvakanyanya simba rekushandisa kwepurasitiki. Mukusarudzwa kwezvinhu, zvinofanirwa kufunga nezvekushandiswa kwenzvimbo uye zvimwe zvikamu nekukanganiswa kwekunyatsojeka. Fiber kusimbiswa kunogona kuderedza iyo yekuisa mvura yemvura yekunyora, kuitira kuti ishande mukupisa kwakanyanya, humi hombe. Nylon uye girazi fiber affinity yakanaka kwazvo. Kazhinji inoshandiswa mukugadzirwa kwemazino, mazino, jasi rejasi, maFA mapfupa, mesh mabhegi, tambo, mabhegi, mabhegi emichero uye zvichingodaro. Isiri-ine chepfu, asi kwete kusangana kwenguva refu neAcid naAlkali. Zvakakosha kucherechedza izvozvo, mushure mekuwedzera girazi fiber, simba retsiva reNylon rinogona kuwedzerwa neinenge 2 nguva, uye kuramba simba kunodzikiswa kunovandudzwa nenzira kwayo.

2. Kurasikirwa kwechiedza kuramba. Munzvimbo refu-refu-tembiricha ichave yexidized ine okisijeni mumhepo, kutanga kwerudzi rwebhuruu, ichiteverwa nekuputswa kwepamhepo kupaza.

3. Injection inoumbwa tekinoroji zvinodiwa zvinonyanya kuitika: Kuvapo kwekutsvaga huwandu hwemvura kuchakonzera kukuvadza kukuru kumhando yekuumbwa; Nekuda kwekuwedzera kwekuwedzera zvekuwedzera kuitira kuti dimensional kugadzikana kwechigadzirwa kwakanyanya kuoma kudzora; Kuvapo kwemakona akapinza muzvigadzirwa kunotungamira kushushikana kushushikana uye kuderedza iyo mechan simba; Borness, kana kusafanana kuchaita kuti ubve mukukanganisa, kushatirisa kwezvikamu; mushure mekugadzirisa zvikamu zvezvakanyanya zvekutanga zvinodiwa zvemidziyo.

4. Tora mvura, doro uye nyungudika, kwete kuramba kune yakasimba acids uye oxidizers, haigone kushandiswa seyakaida-kuramba zvinhu.
