- AS
1. Kushanda kweAS
AS imhando ye propylene-styrene copolymer, inonziwo SAN, ine huremu hweinenge 1.07g/cm3. Haiwanzo pwanyika nekunetseka mukati. Ine kujeka kwakanyanya, tembiricha inonyorovesa uye simba rekukanganisa kupfuura PS, uye haigone kuramba kuneta zvakanyanya.
2. Kushandiswa kweAS
Matireyi, makapu, ndiro dzetafura, zvikamu zvefiriji, makiyi, zvishandiso zvemwenje, zvishongo, magirazi emidziyo, mabhokisi ekurongedza, zvinhu zvekushandisa, magirosa egasi, mibato yebhurashi remazino, nezvimwewo.
3. AS mamiriro ekugadzirisa
Tembiricha yekushanda kweAS inowanzo kuve 210~250℃. Chinhu ichi chiri nyore kunyudza hunyoro uye chinoda kuomeswa kweanopfuura awa imwe chete chisati chagadzirwa. Kuyerera kwacho kwakaderera zvishoma pane PS, saka kumanikidzwa kwejekiseni kwakakwirawo zvishoma, uye tembiricha yeforoma inodzorwa pa45~75℃ iri nani.
- ABS
1. Kushanda kweABS
ABS i acrylonitrile-butadiene-styrene terpolymer. Ipolymer isina chimiro ine density inosvika 1.05g/cm3. Ine simba guru remakanika uye hunhu hwakanaka hwe "vertical, tough and steel". ABS ipurasitiki yeinjiniya inoshandiswa zvakanyanya ine mhando dzakasiyana siyana uye mashandisirwo akasiyana-siyana. Inonziwo "general engineering plastic" (MBS inonzi transparent ABS). Iri nyore kugadzira nekugadzirisa, haina makemikari akasimba, uye zvigadzirwa zviri nyore kuputirwa nemagetsi.
2. Kushandiswa kweABS
Maimpeller epombi, mabheringi, mibato, mapaipi, mabhokisi emidziyo yemagetsi, zvikamu zvezvigadzirwa zvemagetsi, matoyi, mabhokisi ewachi, mabhokisi emidziyo, mabhokisi etangi remvura, mabhokisi ekuchengetedza anotonhorera uye mabhokisi emukati mefiriji.
3. Hunhu hwemaitiro eABS
(1) ABS ine hygroscopicity yakanyanya uye haidziviriri kupisa zvakanyanya. Inofanira kuomeswa zvakakwana uye kupiswa nemoto usati waumbwa nekugadzirisa kuti hunyoro huve pasi pe0.03%.
(2) Kunyunguduka kweABS resin hakunyanyi kukanganiswa nekupisa (kwakasiyana nemamwe maresini asina chimiro). Kunyangwe tembiricha yeABS yejekiseni yakakwira zvishoma pane yePS, haina tembiricha yakareruka sePS, uye kupisa kweblind hakugone kushandiswa. Kuti uderedze kusimba kwayo, unogona kuwedzera kumhanya kwescrew kana kuwedzera kumanikidzwa/kumhanya kwejekiseni kuti uwedzere kuyerera kwayo. Tembiricha yekugadzirwa kwayo ndeye 190~235℃.
(3) Kunyungudika kweABS kuri pakati nepakati, kwakakwirira kupfuura kwePS, HIPS, neAS, uye kuyerera kwayo kwakaderera, saka kumanikidzwa kwakawanda kwejekiseni kunodiwa.
(4) ABS ine simba rakanaka nekumhanya kwepakati nepakati kwejekiseni (kunze kwekunge maumbirwo akaomarara uye zvikamu zvitete zvichida kumhanya kwakakwirira kwejekiseni), muromo wechigadzirwa unowanzo kanganiswa nemhepo.
(5) Tembiricha yekuumba ABS yakakwira zvakanyanya, uye tembiricha yayo yekuumba inowanzo gadziriswa pakati pe45 ne80°C. Pakugadzira zvigadzirwa zvakakura, tembiricha yemuforoma wakagadzika (mould yekumberi) inowanzo kuve yakakwira ne5°C kupfuura yemuforoma unofambiswa (mould yekumashure).
(6) ABS haifanirwe kugara mubharero rinopisa zvakanyanya kwenguva yakareba (inofanira kunge iri pasi pemaminitsi makumi matatu), zvikasadaro inogona kuora nyore nyore yoita yero.
- PMMA
1. Kushanda kwePMMA
PMMA ipolymer isina chimiro, inozivikanwa seplexiglass (sub-acrylic), ine density inosvika 1.18g/cm3. Ine kujeka kwakanaka uye inofambisa chiedza che92%. Ichinhu chakanaka chemaziso; ine resistance yakanaka pakupisa (resistance yakanaka pakupisa). Tembiricha yekuchinja kwayo i98°C). Chigadzirwa chayo chine simba repakati nepakati uye kuomarara kwakaderera pamusoro. Inokwenywa nyore nyore nezvinhu zvakaoma uye inosiya mavanga. Kana ichienzaniswa nePS, haisi nyore kuputsika.
2. Kushandiswa kwePMMA
Magirazi ezvishandiso, zvigadzirwa zvemaziso, midziyo yemagetsi, michina yekurapa, mamodheru anoonekera, zvishongo, magirazi ezuva, mazino emazino, mabhodhibhodhi, mapaneru ewachi, marambi emushure memotokari, magirazi epamberi, nezvimwewo.
3. Hunhu hwemaitiro ePMMA
Zvinodiwa pakugadzirisa PMMA zvakasimba. Inonyanya kubatwa nehunyoro nekupisa. Inofanira kuomeswa zvizere isati yagadziriswa. Kunyungudika kwayo kwakakwira, saka inoda kuumbwa pakupisa kwakanyanya (219 ~ 240℃) uye kumanikidzwa. Kupisa kwemould kuri pakati pe65 ~ 80℃ kuri nani. Kugadzikana kwekupisa kwePMMA hakuna kunaka. Ichaderedzwa nekupisa kwakanyanya kana kugara pakupisa kwakanyanya kwenguva yakareba. Kumhanya kwescrew hakufanirwe kunge kwakanyanya (inenge 60rpm), sezvo zviri nyore kuitika muzvikamu zvePMMA zvakakora. Chiitiko che "vaid" chinoda mageti makuru uye mamiriro e "kupisa kwakanyanya kwezvinhu, kupisa kwakanyanya kwemould, kunonoka" kuti chigadziriswe.
4. Chii chinonzi acrylic (PMMA)?
Acrylic (PMMA) ipurasitiki yakajeka, yakaoma inowanzo shandiswa panzvimbo pegirazi muzvigadzirwa zvakaita semahwindo asingaputsike, zviratidzo zvine chiedza, magirazi epadenga uye macanopies endege. PMMA ndeyemhuri yakakosha yema acrylic resins. Zita remakemikari re acrylic ipolymethyl methacrylate (PMMA), inova synthetic resin yakagadzirwa kubva ku methyl methacrylate.
Polymethylmethacrylate (PMMA) inozivikanwawo se acrylic, acrylic glass, uye inowanikwa pasi pemazita ekutengeserana uye mabrandi akadai seCrylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, uye Perspex, pakati pemamwe. Polymethylmethacrylate (PMMA) inowanzo shandiswa muchimiro chepepa senzira yakareruka kana isingaputsike panzvimbo pegirazi. PMMA inoshandiswawo se resin yekukanda, inki, uye coating. PMMA chikamu cheboka rezvinhu zvepurasitiki zveinjiniya.
5. Acrylic inogadzirwa sei?
Polymethyl methacrylate inogadzirwa kuburikidza ne polymerization sezvo iri imwe yema polymers ekugadzira. Kutanga, methyl methacrylate inoiswa mumold uye catalyst inowedzerwa kuti ikurumidze maitiro acho. Nekuda kwemaitiro aya e polymerization, PMMA inogona kuumbwa kuita mhando dzakasiyana dzakadai semapepa, maresini, mabhuroko, uye mabhedhi. Glue reAcrylic rinogonawo kubatsira kunyorovesa zvidimbu zvePMMA uye kuzvibatanidza pamwe chete.
PMMA iri nyore kushandisa nenzira dzakasiyana. Inogona kubatanidzwa nezvimwe zvinhu kuti iwedzere kunaka kwayo. Ne thermoforming, inochinjika kana yapiswa uye inosimba kana yatonhodzwa. Inogona kuenzana nehukuru hwayo uchishandisa saw kana laser cutting. Kana yakwenenzverwa, unogona kubvisa mavanga pamusoro uye kubatsira kuchengetedza kunaka kwayo.
6. Ndedzipi mhando dzakasiyana dzeacrylic?
Mhando mbiri huru dzepurasitiki yeacrylic iacrylic yakakandwa uye acrylic yakabviswa. Acrylic yakakandwa inodhura kugadzira asi ine simba riri nani, kugara kwenguva refu, kujeka, thermoforming range uye kugadzikana kupfuura acrylic yakabviswa. Acrylic yakakandwa inopa makemikari akasimba uye kugara kwenguva refu, uye iri nyore kuisa ruvara uye chimiro panguva yekugadzira. Acrylic yakakandwa inowanikwawo mumhando dzakasiyana-siyana dzeukobvu. Acrylic yakakandwa inodhura zvishoma pane acrylic yakakandwa uye inopa acrylic inoshanda zvakanaka kupfuura acrylic yakakandwa (zvichireva kuti simba rayo harisi rakaderera). Acrylic yakakandwa iri nyore kugadzirisa uye kushandisa michina, zvichiita kuti ive imwe nzira yakanaka pane magirazi.
7. Sei acrylic ichinyanya kushandiswa?
Acrylic inowanzoshandiswa nekuti ine hunhu hwakafanana negirazi, asi isina matambudziko ekuputsika. Girazi reAcrylic rine hunhu hwakanaka hwekuona uye rine indekisi yakafanana negirazi kana rakasimba. Nekuda kwehunhu hwaro husingaputsike, vagadziri vanogona kushandisa maacrylic munzvimbo dzinenge girazi rine njodzi zvakanyanya kana kuti ringakundikana (senge submarine periscopes, mahwindo endege, nezvimwewo). Semuenzaniso, chimiro chakajairika chegirazi rinodzivirira bulletproof chidimbu che 1/4-inch-gobvu che acrylic, chinonzi solid acrylic. Acrylic inoshandawo zvakanaka mu injection molding uye inogona kugadzirwa kuita chero chimiro chinogona kugadzirwa nemugadziri we mold. Simba regirazi reAcrylic pamwe nekureruka kwaro pakugadzirisa nekugadzira rinoita kuti rive chinhu chakanaka, izvo zvinotsanangura kuti nei richishandiswa zvakanyanya mumaindasitiri evatengi nemabhizinesi.
