- AS
1. Ukusebenza kwe-AS
I-AS iyi-copolymer ye-propylene-styrene, ebizwa nangokuthi i-SAN, enobukhulu obungaba ngu-1.07g/cm3. Ayithambekele ekuqhekekeni kokucindezeleka kwangaphakathi. Inokucaca okuphezulu, izinga lokushisa eliphakeme lokuthambisa kanye namandla okushaya kune-PS, kanye nokumelana nokukhathala okungekuhle.
2. Ukusetshenziswa kwe-AS
Amathileyi, izinkomishi, izitsha zokudlala etafuleni, izingxenye zesiqandisi, izinkinobho, izesekeli zokukhanyisa, imihlobiso, izibuko zezinsimbi, amabhokisi okupakisha, izinto zokubhala, izibani zegesi, izibambo zamazinyo, njll.
3. Izimo zokucubungula ze-AS
Izinga lokushisa lokucubungula le-AS ngokuvamile lingu-210~250℃. Lokhu kulula ukumunca umswakama futhi kudinga ukomiswa isikhathi esingaphezu kwehora elilodwa ngaphambi kokucubungula. Ukugeleza kwayo kubi kancane kune-PS, ngakho-ke ingcindezi yomjovo nayo iphakeme kancane, futhi izinga lokushisa lesikhunta lilawulwa ku-45~75℃ kungcono.
- I-ABS
1. Ukusebenza kwe-ABS
I-ABS yi-acrylonitrile-butadiene-styrene terpolymer. Iyi-polymer engaguquki enobukhulu obungaba ngu-1.05g/cm3. Inamandla aphezulu okusebenza kanye nezakhiwo ezinhle eziphelele "eziqondile, ezinzima nezensimbi". I-ABS iyipulasitiki yobunjiniyela esetshenziswa kabanzi enezinhlobo ezahlukene kanye nokusetshenziswa okubanzi. Ibizwa nangokuthi "ipulasitiki yobunjiniyela ejwayelekile" (i-MBS ibizwa ngokuthi i-ABS esobala). Kulula ukuyibumba nokuyicubungula, inokumelana okungekuhle kwamakhemikhali, futhi imikhiqizo kulula ukuyibeka nge-electroplated.
2. Ukusetshenziswa kwe-ABS
Ama-impeller ephampu, amabheringi, izibambo, amapayipi, izimbobo zemishini kagesi, izingxenye zomkhiqizo we-elekthronikhi, amathoyizi, izimbobo zamawashi, izimbobo zemishini, izimbobo zethangi lamanzi, izimbobo zokugcina izinto ezibandayo kanye nezimbobo zangaphakathi zesiqandisi.
3. Izici zenqubo ye-ABS
(1) I-ABS ine-hygroscopicity ephezulu kanye nokumelana nokushisa okubi. Kumele yomiswe ngokuphelele futhi ishiswe ngaphambi kokuyibumba nokuyicubungula ukuze kulawulwe umswakama ongaphansi kuka-0.03%.
(2) I-viscosity yokuncibilika kwe-resin ye-ABS ayizweli kakhulu ekushiseni (ihlukile kwamanye ama-resin angenawo ukwakheka). Nakuba izinga lokushisa lokujova le-ABS liphakeme kancane kunele-PS, alinawo amazinga okushisa akhuphukayo akhululekile njenge-PS, futhi ukushisa okungabonakali akukwazi ukusetshenziswa. Ukuze unciphise i-viscosity yayo, ungandisa isivinini sesikulufu noma wandise ingcindezi/isivinini sokujova ukuze uthuthukise ukugeleza kwayo. Izinga lokushisa elijwayelekile lokucubungula lingu-190~235℃.
(3) I-ABS encibilikayo iphakathi nendawo, iphakeme kuneye-PS, HIPS, kanye ne-AS, futhi ukugeleza kwayo kuphansi, ngakho-ke kudingeka ingcindezi ephezulu yomjovo.
(4) I-ABS inomphumela omuhle ngesivinini somjovo esiphakathi kuya kwesiphakathi (ngaphandle kokuthi izimo eziyinkimbinkimbi nezingxenye ezincane zidinga isivinini somjovo esiphezulu), umlomo womkhiqizo uthambekele ekubambeni amamaki omoya.
(5) Izinga lokushisa lokubumba i-ABS liphakeme kakhulu, futhi izinga lokushisa layo lokubumba ngokuvamile lilungiswa phakathi kuka-45 no-80°C. Lapho kukhiqizwa imikhiqizo emikhulu, izinga lokushisa lokubumba okuhleliwe (isikhunta sangaphambili) ngokuvamile liphakeme cishe ngo-5°C kunelokubumba okuhambayo (isikhunta sangemuva).
(6) I-ABS akufanele ihlale emgqonyeni oshisa kakhulu isikhathi eside (kufanele ibe ngaphansi kwemizuzu engama-30), ngaphandle kwalokho izobola kalula futhi ibe phuzi.
- I-PMMA
1. Ukusebenza kwe-PMMA
I-PMMA iyi-polymer engaguquki, eyaziwa kakhulu ngokuthi i-plexiglass (sub-acrylic), enobukhulu obungaba ngu-1.18g/cm3. Inokukhanya okuhle kakhulu kanye nokudlulisa ukukhanya okungu-92%. Iyinto enhle yokubona; inokumelana okuhle nokushisa (ukumelana nokushisa). Izinga lokushisa lokuguquguquka lingu-98°C). Umkhiqizo wayo unamandla aphakathi okusebenza kanye nobunzima obuphansi bomphezulu. Iklwejwa kalula yizinto eziqinile futhi ishiya amabala. Uma iqhathaniswa ne-PS, akulula ukuba buthakathaka.
2. Ukusetshenziswa kwe-PMMA
Amalensi ezinsimbi, imikhiqizo yokukhanya, izinto zikagesi, imishini yezokwelapha, amamodeli abonakalayo, imihlobiso, amalensi elanga, amazinyo okufakelwa, amabhodi okukhangisa, amaphaneli ewashi, izibani zangemuva zezimoto, amafasitela emoto, njll.
3. Izici zenqubo ye-PMMA
Izidingo zokucubungula ze-PMMA ziqinile. Izwela kakhulu kumswakama kanye nokushisa. Kumele yomiswe ngokuphelele ngaphambi kokucubungula. I-viscosity yayo yokuncibilika iphakeme kakhulu, ngakho-ke idinga ukubunjwa ekushiseni okuphezulu (219 ~ 240℃) kanye nengcindezi. Izinga lokushisa lesikhunta liphakathi kuka-65 ~ 80℃ lingcono. Ukuqina kokushisa kwe-PMMA akukuhle kakhulu. Izoncishiswa ukushisa okuphezulu noma ukuhlala ekushiseni okuphezulu isikhathi eside. Ijubane lesikulufu akufanele libe phezulu kakhulu (cishe ngo-60rpm), njengoba kulula ukwenzeka ezingxenyeni ezinkulu ze-PMMA. Isenzakalo "esingenalutho" sidinga amasango amakhulu kanye nezimo zokujova "eziphezulu zezinto, izinga lokushisa eliphezulu lesikhunta, ijubane elincane" ukuze kucutshungulwe.
4. Kuyini i-acrylic (PMMA)?
I-Acrylic (PMMA) iyipulasitiki ecacile neqinile evame ukusetshenziswa esikhundleni sengilazi emikhiqizweni efana namafasitela angaqhekeki, izimpawu ezikhanyisiwe, izibani ezikhanyayo kanye nama-canopies ezindiza. I-PMMA iyingxenye yomndeni obalulekile wama-resin e-acrylic. Igama lamakhemikhali le-acrylic yi-polymethyl methacrylate (PMMA), okuyi-resin yokwenziwa eyenziwe nge-polymer evela ku-methyl methacrylate.
I-Polymethylmethacrylate (PMMA) yaziwa nangokuthi i-acrylic, ingilazi ye-acrylic, futhi itholakala ngaphansi kwamagama okuhweba kanye nemikhiqizo efana ne-Crylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, kanye ne-Perspex, phakathi kwabanye. I-Polymethylmethacrylate (PMMA) ivame ukusetshenziswa ngesimo seshidi njengendlela elula noma engaqhekeki esikhundleni sengilazi. I-PMMA isetshenziswa futhi njenge-resin yokubumba, uyinki, kanye ne-coating. I-PMMA iyingxenye yeqembu lezinto zepulasitiki zobunjiniyela.
5. Yenziwa kanjani i-acrylic?
I-polymethyl methacrylate yenziwa nge-polymerization njengoba ingenye yama-polymer okwenziwa. Okokuqala, i-methyl methacrylate ifakwa esikhumbeni bese kufakwa i-catalyst ukuze kusheshiswe inqubo. Ngenxa yale nqubo ye-polymerization, i-PMMA ingakhiwa ibe yizinhlobo ezahlukene ezifana namashidi, ama-resin, amabhlogo, kanye nama-bead. I-Acrylic glue ingasiza futhi ekuthambiseni izingcezu ze-PMMA futhi izihlanganise ndawonye.
I-PMMA kulula ukuyisebenzisa ngezindlela ezahlukene. Ingahlanganiswa nezinye izinto ukusiza ukuthuthukisa izakhiwo zayo. Nge-thermoforming, iyaguquguquka uma ifudunyezwa futhi iqine uma ipholile. Ingalinganiswa ngendlela efanele kusetshenziswa isaha noma ukusika nge-laser. Uma ipholishiwe, ungasusa imihuzuko ebusweni futhi usize ukugcina ubuqotho bayo.
6. Yiziphi izinhlobo ezahlukene ze-acrylic?
Izinhlobo ezimbili eziyinhloko zepulasitiki ye-acrylic yi-acrylic ephothiwe kanye ne-acrylic ephothiwe. I-acrylic ephothiwe ibiza kakhulu ukuyikhiqiza kodwa inamandla angcono, ukuqina, ukucaca, ububanzi bokubumba kanye nokuqina kune-acrylic ephothiwe. I-acrylic ephothiwe inikeza ukumelana okuhle kwamakhemikhali nokuqina, futhi kulula ukuyipenda nokuyibumba ngesikhathi senqubo yokukhiqiza. I-acrylic ephothiwe iyatholakala futhi ngobukhulu obuhlukahlukene. I-acrylic ephothiwe iyonga kakhulu kune-acrylic ephothiwe futhi inikeza i-acrylic ehambisanayo, esebenza kahle kune-acrylic ephothiwe (ngezindleko zamandla ancishisiwe). I-acrylic ephothiwe kulula ukuyicubungula futhi iyisebenzisa ngomshini, okwenza kube yindlela enhle kakhulu esikhundleni samashidi engilazi ekusetshenzisweni.
7. Kungani i-acrylic isetshenziswa kakhulu kangaka?
I-Acrylic ivame ukusetshenziswa ngoba inezimfanelo ezifanayo nezinzuzo njengengilazi, kodwa ngaphandle kwezinkinga zobuthakathaka. Ingilazi ye-Acrylic inezakhiwo ezinhle kakhulu zokukhanya futhi inenkomba efanayo yokukhanya njengengilazi esimweni esiqinile. Ngenxa yezakhiwo zayo ezingaphuki, abaklami bangasebenzisa ama-acrylic ezindaweni lapho ingilazi ingaba yingozi kakhulu noma ingahluleka khona (njenge-periscopes yomkhumbi-ngwenya, amafasitela ezindiza, njll.). Isibonelo, uhlobo oluvame kakhulu lwengilazi engangenisi izinhlamvu ucezu lwe-acrylic oluyi-1/4-intshi ubukhulu, olubizwa ngokuthi i-acrylic eqinile. I-Acrylic nayo isebenza kahle ekubunjweni komjovo futhi ingakhiwa cishe kunoma yisiphi isimo esingadalwa umenzi wesikhunta. Amandla engilazi ye-acrylic kanye nokulula kwayo kokucutshungulwa nokwenza imishini kuyenza ibe yinto enhle kakhulu, okuchaza ukuthi kungani isetshenziswa kabanzi ezimbonini zabathengi nezentengiselwano.
