Izakhiwo ezijwayelekile zokubumba umjovo

1,I-Polystyrene (PS). Eyaziwa kakhulu ngokuthi irabha eqinile, into engenambala, esobala, ecwebezelayo ye-polystyrene eyi-granular yilezi ezilandelayo:

a, izakhiwo ezinhle ze-optical

b, izakhiwo zikagesi ezinhle kakhulu

c, inqubo elula yokubumba

d. Izici ezinhle zombala

e. Ububi obukhulu buwukuba brittleness

f, izinga lokushisa elimelana nokushisa liphansi (izinga lokushisa eliphezulu lokusetshenziswa ngu-60 ~ 80 degrees Celsius)

g, ukumelana ne-asidi ephansi

2,I-Polypropylene(PP). Ayinambala futhi isobala noma inomsebenzi othile oyimbudumbudu ocwebezelayo, okubizwa ngokuthi i-PP, evame ukwaziwa ngenjoloba ethambile. Ipulasitiki eyikristalu. Izakhiwo ze-polypropylene zimi kanje.

a. Ukugeleza okuhle nokusebenza okuhle kakhulu kokubumba.

b. Ukumelana nokushisa okuhle kakhulu, kungenziwa inzalo ngokubilisa ku-100 degrees Celsius

c. Amandla esivuno esiphezulu; izakhiwo zikagesi ezinhle

d. Ukuphepha komlilo okungekuhle; ukumelana nesimo sezulu esibi, ukuzwela umoya-mpilo, ukungenwa ukukhanya kwe-ultraviolet nokuguga

3,Inayiloni(PA). Ipulasitiki yobunjiniyela, ipulasitiki eyenziwe nge-polyamide resin, ebizwa ngokuthi i-PA. kukhona i-PA6 PA66 PA610 PA1010, njll. Izici zenayiloni zimi kanje.

a, inayiloni inokucwebezela okuphezulu, amandla okusebenza aphezulu, ukuqina okuhle, ukuqina okuphezulu, amandla acindezelayo

b, ukumelana nokukhathala okuvelele, ukumelana nokuguga, ukumelana nokugqwala, ukumelana nokushisa, okungeyona ubuthi, izici zikagesi ezinhle kakhulu

c, ukumelana nokukhanya okubi, ukumunca kalula amanzi, hhayi ukumelana ne-asidi

4,I-Polyformaldehyde (POM). Eyaziwa nangokuthi impahla yensimbi yomjaho, iwuhlobo lwepulasitiki yobunjiniyela. Izakhiwo kanye nokusetshenziswa kwe-polyformaldehyde

a, i-paraformaldehyde inesakhiwo esicwebe kakhulu, inezici ezinhle kakhulu zemishini, i-modulus ephezulu yokunwebeka, ukuqina kanye nokuqina kobuso nakho kuphakeme kakhulu, kwaziwa ngokuthi "i-metal competitor"

b. I-coefficient encane yokungqubuzana, ukumelana okuhle kakhulu kokugqokwa kanye nokuzigcoba, okwesibili kunenayiloni, kodwa ishibhile kunenayiloni.

c, ukumelana okuhle kwe-solvent, ikakhulukazi izincibilikisi eziphilayo, kodwa hhayi ama-acids aqinile, ama-alkali aqinile nama-oxidizers

d, ukuzinza okuhle kwe-dimensional, ingakha izingxenye ezinembayo

e, ukuncipha kokubumba, ukuzinza okushisayo kumpofu, ukushisa kulula ukubola

5,I-Acrylonitrile-butadiene-styrene (ABS). Ipulasitiki ye-ABS iyi-polystyrene eguquliwe enamandla amakhulu, eyakhiwe i-acrylonitrile, i-butadiene ne-styrene ngesilinganiso esithile sezinhlanganisela ezintathu, ezinophondo lwendlovu olukhanyayo, olukhanyayo, olungenabuthi futhi olungenambitheki.

Izimpawu kanye nokusetshenziswa

a. Amandla aphezulu emishini; ukumelana nomthelela onamandla; ukumelana kahle kwe-creep; lukhuni, lukhuni, lukhuni, njll.

b, Ubuso bezingxenye zepulasitiki ze-ABS bungafakwa

c, i-ABS ingaxutshwa namanye amapulasitiki kanye nerabha ukuze kuthuthukiswe ukusebenza kwayo, njenge-(ABS +PC)

6, I-Polycarbonate (PC). Evame ukwaziwa njengengilazi engangenwa izinhlamvu, iyinto engenabuthi, ayinambitheki, ayinaphunga, into esobala, evuthayo, kodwa ekwazi ukuzicisha ngokwayo ngemva kokushiya umlilo. Izici kanye nokusetshenziswa.

a. Ngokuqina okukhethekile nobulukhuni, inamandla omthelela angcono kakhulu kuzo zonke izinto ze-thermoplastic

b. Ukumelana nokukhasa okuhle kakhulu, ukuzinza okuhle kwe-dimensional, ukunemba okuphezulu kokubumba; ukumelana nokushisa okuhle (ama-120 degrees)

c. Okubi amandla okukhathala aphansi, ukucindezeleka okukhulu kwangaphakathi, ukuqhekeka kalula, nokungagugi kahle kwezingxenye zepulasitiki.

7,I-PC+ABS ingxubevange (PC+ABS). I-PC ehlanganisiwe (amapulasitiki obunjiniyela) kanye ne-ABS (amapulasitiki ahloselwe ukujwayelekile) izinzuzo zakho zombili, zithuthukise ukusebenza kwakho kokubili. Iqukethe i-ABS kanye nokwakheka kwamakhemikhali e-PC, enoketshezi oluhle lwe-ABS nokubunjwa, ukumelana nomthelela we-PC kanye nokumelana nezinguquko zomjikelezo oshisayo nobandayo. Izici

a. Ingasakazwa nge-glue umlomo / isikhunta somlomo omkhulu wamanzi.

b, Surface kungenziwa olufuthwe uwoyela, Plating, metal spray ifilimu.

c. Qaphela ukungezwa kwe-exhaust engaphezulu.

d. Izinto ezisetshenziswayo zivame ukusetshenziswa ekubunjweni komgijimi oshisayo futhi iye yasetshenziswa emikhiqizweni eminingi yokuxhumana yabathengi, njengamakesi omakhalekhukhwini/amakesi wekhompyutha.
