Izinto ezisetshenziswa ngokujwayelekile zokubumba umjovo

Izinto ezisetshenziswa kakhulu zokubumba umjovo zokubumba umjovo zifaka i-ABS, i-PC, i-PE, i-PP, i-PS, i-PA, i-POM, njll. Izinto ezihlukene zinezakhiwo ezahlukene. Lapho ukhetha izinto zokucubungula, ungakhetha ngokuya ngezidingo zokusebenza komkhiqizo ngokwawo.

I-ABS

Ipulasitiki ye-ABS iyi-terpolymer yama-monomers amathathu: i-acrylonitrile (A), i-butadiene (B) ne-styrene (S). Iluphondo lwendlovu olulula, aluboni, ayinabuthi futhi ayinaphunga. Izinto ezisetshenziswayo zitholakala kalula, ukusebenza kukonke kuhle, intengo ishibhile, futhi ukusetshenziswa kubanzi. Ngakho-ke, i-ABS ingenye yepulasitiki yobunjiniyela esetshenziswa kakhulu.

Izici :

● Amandla aphezulu emishini, ukumelana nomthelela oqinile kanye nokumelana kahle nokukhuphuka;

● Inezici zokuqina, ukuqina nokuqina;

● Ubuso bezingxenye zepulasitiki ze-ABS bungafakwa ugesi;

● I-ABS ingaxutshwa namanye amapulasitiki namarabha ukuze kuthuthukiswe izakhiwo zawo, njenge-(ABS + PC).

Izindawo ezijwayelekile zohlelo lokusebenza:

Ivamise ukusetshenziswa ezimotweni, kuma-TV, eziqandisini, emishinini yokuwasha, ama-air conditioner namanye amabhokisi kagesi.

I-PC

Ipulasitiki ye-PC yinto eqinile, eyaziwa ngokuthi ingilazi engangenwa izinhlamvu. Kuyinto engenabuthi, enganambitheki, engenaphunga, esobala futhi ekwazi ukuvutha, kodwa ekwazi ukuzicisha ngokwayo ngemva kokukhishwa emlilweni.

isici:

● Inokuqina nokuqina okukhethekile, futhi inamandla omthelela angcono kakhulu kuzo zonke izinto ze-thermoplastic;

● Ukumelana ne-creep enhle kakhulu, ukuzinza okuhle kwe-dimensional, nokunemba kokubumba okuphezulu;

● Ukumelana nokushisa okuhle (ama-degree angu-120);

● Okubi amandla okukhathala aphansi, ingcindezi enkulu yangaphakathi, nokuqhekeka kalula;

● Izingxenye zepulasitiki azikwazi ukuguga kahle.

Izindawo ezijwayelekile zohlelo lokusebenza:

Imishini kagesi neyebhizinisi (izingxenye zekhompuyutha, izixhumi, njll.), izinto zikagesi (amaprosesa okudla, amadrowa esiqandisi, njll.), imboni yezokuthutha (amalambu emoto angaphambili nangemuva, amaphaneli amathuluzi, njll.).

PP

Iglue ethambile ye-PP, evame ukwaziwa ngeglue ethambile engu-100%, iyi-granular engenambala, esobala noma ecwebezelayo, futhi iyipulasitiki ecwebezelayo.

isici:

● I-fluidity enhle nokusebenza okuhle kakhulu kokubumba;

● Ukumelana nokushisa okuhle kakhulu, kungabiliswa futhi kufakwe inzalo ku-100 degrees Celsius;

● Amandla esivuno esiphezulu;

● Ukusebenza kahle kukagesi;

● Ukuphepha komlilo okungekuhle;

● Alikwazi ukumelana nesimo sezulu esingesihle, liyazwela kumoya-mpilo, futhi lisengozini yokuguga ngenxa yethonya lemisebe ye-ultraviolet.

Izindawo ezijwayelekile zohlelo lokusebenza:

Imboni yezimoto (ikakhulukazi kusetshenziswa i-PP equkethe izithasiselo zensimbi: ama-fenders, imigudu yokukhipha umoya, amafeni, njll.), okokusebenza (ama-gaskets eminyango yomshini wokuwasha izitsha, amapayipi okungenisa umoya okomisa, amafreyimu omshini wokuwasha kanye nekhava, ama-gaskets eminyango yesiqandisi, njll.), Japan Ngemikhiqizo yabathengi (imishini yotshani nengadi efana nemishini yokugunda utshani, njll.).

VULIWE

I-PE ingenye yezinto ezisetshenziswa kakhulu ze-polymer ekuphileni kwansuku zonke. Iqinile ngengcina emhlophe, ine-keratinous kancane, ayinaphunga, ayinambitheki, futhi ayinabuthi. Ngaphandle kwamafilimu, eminye imikhiqizo i-opaque. Lokhu kungenxa yokuthi i-PE ine-crystallinity ephezulu. Ngenxa yeziqu.

isici:

● Imelana nezinga lokushisa eliphansi noma ukubanda, imelana nokugqwala (ayizweli ku-nitric acid), ayincibiliki ezincibilikisini ezivamile ekamelweni lokushisa;

● Ukumuncwa kwamanzi aphansi, ngaphansi kuka-0.01%, ukufakwa kukagesi okuhle kakhulu;

● Inikeza i-ductility ephezulu namandla okuthinta kanye nokungqubuzana okuphansi.

● Ukungeneka kwamanzi aphansi kodwa ukungenwa komoya okuphezulu, kulungele ukupakishwa kobufakazi bomswakama;

● Ingaphezulu alinayo i-polar futhi kunzima ukulihlanganisa nokuliphrinta;

● Ayimelani ne-UV futhi imelane nesimo sezulu, iba brittle ekukhanyeni kwelanga;

● Izinga lokushwabana likhulu futhi kulula ukushwabana nokonakala (izinga lokushwabana: 1.5~3.0%).

Izindawo ezijwayelekile zohlelo lokusebenza:

Isetshenziswa kabanzi ekwakhiweni kwezikhwama zepulasitiki, amafilimu epulasitiki, izintambo zocingo kanye nezintambo zokumboza izintambo, njll.

PS

I-PS, eyaziwa ngokuthi i-hard glue, iyinto engenambala, esobala, ecwebezelayo eyimbudumbudu.

isici:

● Ukusebenza okuhle kokubona;

● Ukusebenza kahle kukagesi;

● Kulula ukwakha nokucubungula;

● Ukusebenza kahle kombala;

● I-drawback enkulu iwukuba brittleness;

● Ukushisa okuphansi kokumelana nokushisa (izinga lokushisa eliphezulu lokusebenza 60 ~ 80 degrees Celsius);

● Ukungazweli kahle kwe-asidi.

Izindawo ezijwayelekile zohlelo lokusebenza:

Ukupakishwa komkhiqizo, imikhiqizo yasendlini (i-tableware, amathreyi, njll.), ugesi (iziqukathi ezibonisa ngale, iziphazamisi ezikhanyayo, amafilimu avikelayo, njll.)

PA

I-PA iyipulasitiki yobunjiniyela, eyakhiwe nge-polyamide resin, ehlanganisa i-PA6 PA66 PA610 PA1010, njll.

isici:

● Inayiloni icwebezela kakhulu;

● Amandla aphezulu emishini nokuqina okuhle;

● Inamandla amakhulu okunyakazisa namandla acindezelayo;

● Ukumelana nokukhathala okuvelele, ukumelana nokuguga, ukumelana nokugqwala, ukumelana nokushisa, nokungenabo ubuthi;

● Inezinto zikagesi ezinhle kakhulu;

● Alikwazi ukumelana nokukhanya, limunca kalula amanzi, futhi alikwazi ukumelana ne-asidi.

Izindawo ezijwayelekile zohlelo lokusebenza:

Isetshenziswa kabanzi ezingxenyeni zesakhiwo ngenxa yamandla ayo amahle wemishini nokuqina. Ngenxa yezakhiwo zayo ezinhle zokumelana nokugqoka, ibuye isetshenziswe ekwenzeni ama-bearings.

BHEKA

I-POM iyimpahla eqinile kanye nepulasitiki yobunjiniyela. I-Polyoxymethylene inesakhiwo sekristalu esinezici ezinhle kakhulu zemishini, i-modulus ephezulu yokunwebeka, ukuqina okuphezulu nokuqina kobuso, futhi yaziwa ngokuthi "umqhudelana wensimbi."

isici:

● I-coefficient encane yokungqubuzana, ukumelana okuhle kakhulu kokugqokwa nokuzithambisa, okwesibili kunenayiloni, kodwa ishibhile kunenayiloni;

● Ukungazweli kahle kwezincibilikisi, ikakhulukazi izincibilikisi eziphilayo, kodwa azikwazi ukumelana nama-asidi aqinile, ama-alkali nama-oxidants;

● Ukuzinza okuhle kohlangothi futhi kungakha izingxenye ezinembayo;

● I-shrinkage yokubumba inkulu, ukuzinza kwe-thermal kubi, futhi kulula ukubola lapho kushisa.

Izindawo ezijwayelekile zohlelo lokusebenza:

I-POM ine-coefficient ephansi kakhulu yokungqubuzana nokuzinza okuhle kwejometri, okuyenza ifaneleke ngokukhethekile ukwenza amagiya namabheringi. Ngenxa yokuthi futhi inokumelana nokushisa okuphezulu, iphinde isetshenziswe ezingxenyeni zamapayipi (ama-valve amapayipi, izindlu zephampu), imishini yotshani, njll.
