Ihlaziywe ngoNovemba 2, 2022
Nali iziko leendaba loshishino lokubumba inaliti ye-Baiyear.Okulandelayo, i-Baiyear iya kwahlula inkqubo yokubumba inaliti ibe ngamanqaku amaninzi ukwazisa uhlalutyo lwezinto ezikrwada zenkqubo yokubumba inaliti, kuba kukho umxholo omninzi kakhulu.Elilandelayo linqaku lokuqala.
(1).PS (ipolystyrene)
1. Ukusebenza kwePS:
I-PS i-polymer e-amorphous ene-fluidity elungileyo kunye nokufunxa kwamanzi aphantsi (ngaphantsi kwe-00.2%).Yiplastiki ecacileyo ekulula ukuyenza kunye nokusebenza.Iimveliso zayo zine-transmittance ekhanyayo ye-88-92%, amandla okuqina okuqinileyo kunye nobunzima obuphezulu.Nangona kunjalo, iimveliso ze-PS zine-brittle, zixhomekeke ekuqhekekeni koxinzelelo lwangaphakathi, zinokumelana nokushisa okungahambi kakuhle (60-80 ° C), azinatyhefu, kwaye zinobunzima obuthile malunga ne-1.04g \ cm3 (inkulu kancinane kunamanzi).
I-Molding shrinkage (ixabiso ngokubanzi li-0.004-0.007in / in), i-PS ebonakalayo - eli gama libonisa kuphela ukucaca kwe-resin, kungekhona i-crystallinity.(Iimpawu zeChemical kunye nezomzimba: Uninzi lwe-PSs zorhwebo ziselubala, izinto ze-amorphous. I-PS inozinzo oluhle kakhulu lwejometri, uzinzo lwe-thermal, iipropati zokuhanjiswa kwe-optical, iipropati zokugquma umbane, kunye nomkhwa omncinci kakhulu wokufunxa ukufuma. Iyakwazi ukumelana namanzi, i-diluted inorganic acids , kodwa inokugqwaliswa ziiasidi ezinamandla zokuxilisa ezifana ne-asidi yesulfuric exubileyo, kwaye inokudumba kunye nokonakala kwezinye izinyibilikisi eziphilayo.)
2. Iimpawu zenkqubo yePS:
Indawo yokunyibilika ye-PS yi-166 °C, iqondo lokushisa lokulungisa lihlala li-185-215 °C, kwaye iqondo lokunyibilika liyi-180 ~ 280 °C.Kwizinto ezithintela amadangatye, umda ophezulu yi-250 ° C, kwaye iqondo lokushisa lokubola li malunga ne-290 ° C, ngoko ke uluhlu lwalo lokushisa lubanzi.
Ubushushu bomngundo yi-40 ~ 50 ℃, uxinzelelo lwenaliti: 200 ~ 600bar, isantya sokutofa siyacetyiswa ukuba usebenzise isantya sokutofa ngokukhawuleza, kwaye iimbaleki kunye namasango anokusebenzisa zonke iindidi eziqhelekileyo zamasango.Izinto ze-PS ngokuqhelekileyo akufuneki zomiswe ngaphambi kokuba zigcinwe ngaphandle kokuba zigcinwe ngokungafanelekanga.Ukuba ukomisa kuyadingeka, iimeko zokumisa ezicetyiswayo zi-80C kwiiyure ze-2 ~ 3.
Ngenxa yobushushu obuthile obuphantsi be-PS, ezinye iimolds zinokukhawuleza kwaye ziqiniswe xa zenziwe ukuba zichithe ubushushu.Izinga lokupholisa likhawuleza kunelo lezinto eziqhelekileyo eziqhelekileyo, kwaye ixesha lokuvula i-mold lingaba ngaphambili.Ixesha leplastiki kunye nexesha lokupholisa lifutshane, kwaye ixesha lomjikelezo wokubumba liya kuncitshiswa;Iglosi yeemveliso ze-PS ingcono njengoko ubushushu bomngundo bukhula.
3.Usetyenziso oluqhelekileyo: iimveliso zokupakisha (izikhongozeli, iikepusi, iibhotile), izinto zonyango ezilahlwayo, iithoyi, iikomityi, iimela, iireli zeteyiphu, iifestile zesaqhwithi kunye neemveliso ezininzi zamagwebu - iibhokisi zamaqanda.Iitreyi zokupakisha zenyama kunye neenkukhu, iileyibhile zebhotile kunye nezixhobo zokupakisha ze-PS ezinegwebu, ukupakishwa kwemveliso, izinto zasendlini (i-cutlery, iitreyi, njl. njl.), zombane (izikhongozeli ezicacileyo, ii-diffusers ezikhanyayo, iifilimu ezikhuselayo, njl. njl.).
(2).I-HIPS (ipolystyrene elungisiweyo)
1. Ukusebenza kwe-HIPS:
I-HIPS yinto elungisiweyo ye-PS.Iqulethe i-5-15% icandelo lerabha kwi-molecule.Ukuqina kwayo malunga namaxesha amane aphezulu kune-PS, kwaye amandla ayo empembelelo aphuculwe kakhulu (impembelelo ephezulu ye-polystyrene).Inomgangatho wokubuyiswa komlilo kunye nokumelana nokuqhekeka koxinzelelo.amabanga, amabanga eglosi aphezulu, amabakala anamandla axhomis’ amehlo kakhulu, amabanga aqiniswe ngegilasi fiber, kunye nentsalela yamanqaku aguqukayo asezantsi.
Ezinye iimpawu ezibalulekileyo ze-HIPS eziqhelekileyo: amandla okugoba 13.8-55.1MPa;amandla okuqina 13.8-41.4MPa;elongation ngexesha lekhefu 15-75%;ubuninzi 1.035-1.04 g/ml;Iingenelo.Amanqaku e-HIPS akacacanga.I-HIPS ine-absorption yamanzi ephantsi kwaye inokucutshungulwa ngaphandle kokumisa kwangaphambili.
2. Iimpawu zenkqubo ye-HIPS:
Ngenxa yokuba i-molecule ye-HIPS iqulethe i-rubber eyi-5-15%, echaphazela ukumanzi kwayo kwinqanaba elithile, uxinzelelo lwenaliti kunye nobushushu bokubumba kufuneka bube phezulu.Izinga lokupholisa lalo lincinci kunelo le-PS, ngoko ke ngokwaneleyo ukubamba uxinzelelo, ixesha lokubamba kunye nexesha lokupholisa liyadingeka.Umjikelo wokubumba uya kuba mde kancinane kunolo we-PS, kwaye iqondo lobushushu lokulungisa liqhele ukuba yi-190-240 °C.
Iinreyithi zeHIPS zifunxa ukufuma kancinci kancinci, ngoko ke ukoma akufuneki.Ngamanye amaxesha umswakama obuninzi phezu kwezinto eziphathekayo unokufunxa, uchaphazela umgangatho wokubonakala kwemveliso yokugqibela.Ukufuma okugqithisileyo kunokususwa ngokumisa kwi-160 ° F kwiiyure ezingama-2-3.Kukho ingxaki ekhethekileyo "yomphetho omhlophe" kwiindawo ze-HIPS, ezinokuthi ziphuculwe ngokunyusa ukushisa kwe-mold kunye ne-clamping force, ukunciphisa uxinzelelo lokubamba kunye nexesha, njl., kwaye iphethini yamanzi kwimveliso iya kubonakala ngakumbi.
4.Imimandla yesicelo esiqhelekileyo: Iindawo eziphambili zesicelo zipakisha kunye nezinto ezilahlayo, izixhobo, izixhobo zasekhaya, iithoyizi kunye neemveliso zokuzonwabisa, kunye neshishini lokwakha.Ibanga elibuyisela umlilo (i-UL V-0 kunye ne-UL 5-V), i-polystyrene enganyangekiyo yempembelelo iye yaveliswa kwaye isetyenziswa ngokubanzi kwiibhokisi zeTV, oomatshini zoshishino kunye neemveliso zombane.
Ukuqhubeka, ukuba ufuna ukwazi ngakumbi, nceda uzive ukhululekile ukuqhagamshelana nathi.I-Baiyear ngumzi-mveliso omkhulu oqukayo odibanisa ukwenziwa komngundo weplastiki, ukubumba inaliti kunye nokusetyenzwa kwentsimbi.Okanye unokuqhubeka nokunikela ingqalelo kwiziko leendaba lewebhusayithi yethu esemthethweni: www.baidasy.com, siya kuqhubeka nokuhlaziya iindaba zolwazi ezinxulumene neshishini lokulungisa inaliti.
