Nasi isikhungo sezindaba somkhakha wokubumba umjovo we-Baiyear.Okulandelayo, i-Baiyear izohlukanisa inqubo yokubumba umjovo ibe izindatshana ezimbalwa ukwethula ukuhlaziywa kwezinto ezingavuthiwe zenqubo yokubumba umjovo, ngoba kunokuqukethwe okuningi kakhulu.Okulandelayo isihloko sokuqala.
(1).I-PS (i-polystyrene)
1. Ukusebenza kwe-PS:
I-PS iyi-polymer e-amorphous ene-fluidity enhle kanye nokumuncwa kwamanzi aphansi (ngaphansi kuka-00.2%).Iwupulasitiki obala okulula ukuwenza nokuwucubungula.Imikhiqizo yayo ine-transmittance elula engu-88-92%, amandla okuthayela aqinile kanye nokuqina okuphezulu.Kodwa-ke, imikhiqizo ye-PS i-brittle, ijwayele ukuqhekeka kwengcindezi yangaphakathi, inokumelana nokushisa okuphansi (60-80 ° C), ayinabo ubuthi, futhi inobunzima obuthile obungaba ngu-1.04g\cm3 (inkulu kancane kunamanzi).
Ukuncipha kokubumba (inani ngokuvamile liyi-0.004-0.007in/in), i-PS esobala - leli gama libonisa kuphela ukukhanya kwe-resin, hhayi i-crystallinity.(Izakhiwo zamakhemikhali nezomzimba: Ama-PS amaningi okuhweba anezinto ezibonakalayo, ezi-amorphous. I-PS inokusimama okuhle kakhulu kwejometri, ukuzinza kwe-thermal, izakhiwo zokudlulisa amehlo, izici zokuvikela ugesi, kanye nokuthambekela okuncane kakhulu kokumunca umswakama. Ingazweli emanzini, i-diluted inorganic acids , kodwa ingagqwaliswa ama-asidi e-oxidizing aqinile njenge-concentrated sulfuric acid, futhi angavuvuka futhi akhubazeke kwezinye izinyibilikisi eziphilayo.)
2. Izici zenqubo ye-PS:
Indawo encibilikayo ye-PS ingu-166 °C, izinga lokushisa lokucubungula ngokuvamile liyi-185-215 °C, futhi izinga lokushisa elincibilikayo lingu-180~280 °C.Ngezinto ezivimbela ilangabi, umkhawulo ongaphezulu ngu-250 ° C, futhi izinga lokushisa lokubola lingaba ngu-290 ° C, ngakho-ke izinga lokushisa lokucubungula libanzi.
Izinga lokushisa lesikhunta lingu-40 ~ 50℃, ingcindezi yomjovo: 200 ~ 600bar, isivinini somjovo siyanconywa ukusebenzisa isivinini somjovo osheshayo, futhi abagijimi namasango bangasebenzisa zonke izinhlobo ezivamile zamasango.Izinto ze-PS ngokuvamile azidingi ukuba zomiswe ngaphambi kokuba zicutshungulwe ngaphandle kokuthi zigcinwe ngendlela engafanele.Uma ukomiswa kuyadingeka, izimo zokomisa ezinconyiwe zingu-80C amahora angu-2 ~ 3.
Ngenxa yokushisa okuthile okuphansi kwe-PS, ezinye isikhunta singafinyezwa ngokushesha futhi siqine uma senziwe ukuze sikhiphe ukushisa.Izinga lokupholisa liyashesha ukwedlula lelo lezinto ezivamile zokusetshenziswa, futhi isikhathi sokuvula isikhunta singase sibe ngaphambili.Isikhathi seplastiki kanye nesikhathi sokupholisa sifushane, futhi isikhathi somjikelezo wokubumba sizoncishiswa;ukucwebezela kwemikhiqizo ye-PS kungcono njengoba izinga lokushisa lesikhunta likhula.
3.Izinhlelo zokusebenza ezijwayelekile: imikhiqizo yokupakisha (izitsha, amakepisi, amabhodlela), izinto zokwelapha ezilahlwayo, amathoyizi, izinkomishi, imimese, izinsimbi zamatheyiphu, amafasitela eziphepho kanye nemikhiqizo eminingi yegwebu - amabhokisi amaqanda.Amathreyi okupakisha enyama nezinkukhu, amalebula amabhodlela nezinto zokupakisha ze-PS ezinegwebu, ukupakishwa komkhiqizo, izinto zasendlini (izinto zokusika, amathreyi, njll.), ugesi (iziqukathi ezisobala, iziphazamisi ezikhanyayo, amafilimu avikelayo, njll.).
(2).I-HIPS (i-polystyrene eshintshiwe)
1. Ukusebenza kwe-HIPS:
I-HIPS yinto eguquliwe ye-PS.Iqukethe ingxenye yerabha engu-5-15% ku-molecule.Ukuqina kwayo kuphakeme ngokuphindwe kane kunokwe-PS, futhi amandla ayo okuthinta athuthukiswa kakhulu (i-polystyrene enomthelela ophezulu).Inebanga lokubuyiswa kwamalangabi kanye nokumelana nokuqhekeka kwengcindezi.amamaki, amamaki acwebezelayo aphezulu, amamaki anamandla omthelela aphezulu kakhulu, amamaki aqiniswe ngefayibha yengilazi, kanye namabanga aphansi ayizinsalela aguqukayo.
Ezinye izici ezibalulekile ze-HIPS ejwayelekile: amandla okugoba 13.8-55.1MPa;amandla e-tensile 13.8-41.4MPa;ukuphakama ngesikhathi sekhefu 15-75%;ukuminyana 1.035-1.04 g/ml;Izinzuzo.Izihloko ze-HIPS zi-opaque.I-HIPS inokumuncwa okuphansi kwamanzi futhi ingacutshungulwa ngaphandle kokoma kwangaphambili.
2. Izici zenqubo ye-HIPS:
Ngenxa yokuthi i-molecule ye-HIPS iqukethe irabha engu-5-15%, ethinta uketshezi kwayo ngezinga elithile, ingcindezi yomjovo kanye nezinga lokushisa lokubumba kufanele libe phezulu.Izinga lokupholisa layo lihamba kancane kunele-PS, ngakho-ke ingcindezi yokubamba eyanele, isikhathi sokubamba kanye nesikhathi sokupholisa kuyadingeka.Umjikelezo wokubumba uzoba mude kancane kunowe-PS, futhi izinga lokushisa lokucubungula ngokuvamile liyi-190-240 °C.
Ama-resin e-HIPS amunca umswakama kancane, ngakho ukoma ngokuvamile akudingekile.Ngezinye izikhathi umswakama omningi ebusweni bezinto ezibonakalayo ungamuncwa, uthinte izinga lokubukeka lomkhiqizo wokugcina.Umswakama owedlulele ungasuswa ngokumisa ku-160 ° F amahora angu-2-3.Kunenkinga ekhethekile "emhlophe enqenqemeni" ezingxenyeni ze-HIPS, ezingathuthukiswa ngokwandisa izinga lokushisa lesikhunta namandla okubamba, ukunciphisa ukucindezela kokubamba kanye nesikhathi, njll., futhi iphethini yamanzi emkhiqizweni izoba sobala kakhulu.
4.Izindawo zokufaka izicelo ezijwayelekile: Izindawo ezisemqoka ezifaka isicelo amaphakheji kanye nezinto ezilahlwayo, izinsimbi, izinto zasendlini, amathoyizi nemikhiqizo yokuzijabulisa, kanye nemboni yezokwakha.Ibanga le-flame retardant (UL V-0 kanye ne-UL 5-V), i-polystyrene engazweli nomthelela iye yakhiqizwa futhi yasetshenziswa kabanzi kumakesi we-TV, imishini yebhizinisi nemikhiqizo kagesi.
Ukuze uqhubeke, uma ufuna ukwazi okwengeziwe, sicela ukhululeke ukuxhumana nathi.I-Baiyear iyifekthri enkulu ehlanganisa ukukhiqiza isikhunta sepulasitiki, ukubumba umjovo kanye nokucubungula insimbi yeshidi.Noma ungaqhubeka nokunaka isikhungo sezindaba sewebhusayithi yethu esemthethweni: www.baidasy.com, sizoqhubeka nokubuyekeza izindaba zolwazi ezihlobene nomkhakha wokucubungula umjovo wokubumba.
