- AS
1. AS kuita
AS inonzi propylene-styrene copolymer, inonziwo SAN, ine density inoita 1.07g/cm3. Haisi kutarisana nekushungurudzika kwemukati kuputika. Iine kujeka kwepamusoro, tembiricha yakapfava uye simba rekuita kupfuura PS, uye kushomeka kwekuneta.
2. Kushandiswa kweAS
Matireyi, makapu, tableware, mafiriji macompartments, mapfundo, zvishongedzo zvemwenje, zvishongo, magirazi ezviridzwa, mabhokisi ekurongedzera, stationery, magasi emagetsi, zvibatiso zvebhurasho remazino, nezvimwe.
3. AS kugadzirisa mamiriro
Iyo tembiricha yekugadzirisa yeAS inowanzoita 210 ~ 250 ℃. Nyaya iyi iri nyore kutora hunyoro uye inoda kuomeswa kweinopfuura awa imwe isati yagadziriswa. Kunyungudika kwayo kwakashata zvishoma kupfuura PS, saka kudzvanywa kwejekiseni kwakakwirawo zvishoma, uye tembiricha yekuumbwa inodzorwa pa45 ~ 75 ℃ iri nani.
- ABS
1. ABS kuita
ABS inonzi acrylonitrile-butadiene-styrene terpolymer. Iyo amorphous polymer ine density inoita 1.05g/cm3. Iyo ine yakakwira mechanic simba uye yakanaka yakazara zvivakwa zve "vertical, yakaoma uye simbi". ABS ipurasitiki yeinjiniya inoshandiswa zvakanyanya nemhando dzakasiyana siyana uye kushandiswa kwakakura. Inonzi zvakare "general engineering plastic" (MBS inonzi transparent ABS). Zviri nyore kuumba uye kugadzirisa, ine kushomeka kwemakemikari kuramba, uye zvigadzirwa zviri nyore kuve electroplated.
2. Kushandiswa kweABS
Mapombi emapombi, mabearings, handles, pombi, magetsi emidziyo yemagetsi, zvigadzirwa zvemagetsi zvigadzirwa, matoyi, makesi ewachi, makesi emidziyo, matangi emvura, chengetedzo inotonhora uye firiji yemukati casings.
3. ABS maitiro maitiro
(1) ABS ine yakakwira hygroscopicity uye yakashata tembiricha kuramba. Inofanirwa kuomeswa zvizere uye preheated isati yaumbwa uye kugadzirisa kudzora hunyoro huri pasi pe0.03%.
(2) Iyo yakanyunguduka viscosity yeABS resin hainyanyi kunzwa tembiricha (yakasiyana nemamwe amorphous resins). Kunyangwe tembiricha yejekiseni yeABS yakakwira zvishoma pane iyo yePS, haina tembiricha yakasununguka inokwira senge PS, uye kupisa kwemapofu hakugone kushandiswa. Kuti uderedze viscosity yayo, unogona kuwedzera screw kumhanya kana kuwedzera jekiseni pressure/kumhanya kuti uvandudze fluidity. Iyo yakawanda yekugadzirisa tembiricha ndeye 190 ~ 235 ℃.
(3) The melt viscosity yeABS iripakati, yakakwirira kudarika iyo yePS, HIPS, uye AS, uye kunyunguduka kwayo kwakaderera, saka kukwirira kwejekiseni kunodiwa.
(4) ABS ine mhedzisiro yakanaka ine epakati kusvika epakati jekiseni kumhanya (kunze kwekunge maumbirwo akaomarara uye nhengo dzakatetepa dzichida kumhanya kwejekiseni kwakakwira), muromo wechigadzirwa unotarirwa kumaki emhepo.
(5) ABS molding tembiricha yakakwira zvakati, uye tembiricha yayo mold inowanzogadziriswa pakati pe45 ne80°C. Paunenge uchigadzira zvigadzirwa zvakakura, tembiricha yeyakagadziriswa mold (yekumberi mold) kazhinji inenge 5 ° C yakakwirira kupfuura iyo inofambiswa mold (kumashure mold).
(6) ABS haifanire kugara mubhodhoro repamusoro-soro kwenguva yakareba (inofanira kunge isingasviki maminetsi makumi matatu), zvikasadaro inoora nyore uye kushanduka yero.
- PMMA
1. Kuita kwePMMA
PMMA iamorphous polymer, inowanzozivikanwa se plexiglass (sub-acrylic), ine density inosvika 1.18g/cm3. Iyo ine kujeka kwakanakisa uye mwenje kuendesa kwe92%. Icho chinhu chakanaka chemaziso; ine kunaka kwekudzivirira kupisa (kupisa kupisa). Deformation tembiricha i98°C). Chigadzirwa chayo chine yepakati mechanical simba uye yakaderera pamusoro kuoma. Inokwenywa nyore nyore nezvinhu zvakaoma uye inosiya maronda. Kuenzaniswa nePS, hazvisi nyore kuve wakaoma.
2. Kushandiswa kwePMMA
Malensi emidziyo, zvigadzirwa zvemaziso, midziyo yemagetsi, midziyo yekurapa, modhi inoonekera, zvekushongedza, malenzi ezuva, mazino, zvikwangwani, mawachi, maraiti emota, mahwindi emhepo, nezvimwe.
3. Maitiro maitiro ePMMA
Izvo zvinodiwa zvekugadzirisa zvePMMA zvakasimba. Inonyatsonzwa kune unyoro uye kupisa. Inofanira kuomeswa zvakakwana isati yagadziriswa. Kunyunguduka kwayo kunenge kwakakwira, saka inoda kuumbwa patembiricha yepamusoro (219 ~ 240 ℃) uye kudzvanywa. Iyo tembiricha yekuumbwa iri pakati pe65 ~ 80 ℃ iri nani. Kugadzikana kwekupisa kwePMMA hakuna kunaka. Ichasvibiswa nekushisa kwepamusoro kana kugara panzvimbo yakakwirira kwenguva yakareba. Iyo screw Speed haifanire kunge yakakwira zvakanyanya (inenge 60rpm), sezvo zviri nyore kuitika munzvimbo dzakakora PMMA. Chiitiko che "void" chinoda magedhi akakura uye "tembiricha yepamusoro yezvinhu, tembiricha yakakwira mold, inononoka kumhanya" jekiseni mamiriro ekugadzirisa.
4. Chii chinonzi acrylic (PMMA)?
Acrylic (PMMA) ipurasitiki yakajeka, yakaoma inowanzoshandiswa panzvimbo yegirazi mune zvigadzirwa zvakadai semahwindo anoputika, zviratidzo zvakavhenekera, skylights uye canopies yendege. PMMA ndeyemhuri yakakosha ye acrylic resins. Zita remakemikari re acrylic ndeye polymethyl methacrylate (PMMA), inova resin yakagadzirwa polymerized kubva kumethyl methacrylate.
Polymethylmethacrylate (PMMA) inozivikanwawo se acrylic, acrylic girazi, uye inowanikwa pasi pemazita ekutengesa uye mhando seCrylux, Plexiglas, Acrylite, Perclax, Astariglas, Lucite, uye Perspex, pakati pevamwe. Polymethylmethacrylate (PMMA) inowanzoshandiswa mupepa fomu seyakareruka kana shatterproof imwe nzira kune girazi. PMMA inoshandiswawo sekukanda resin, inki, uye coating. PMMA chikamu cheinjiniya epurasitiki zvinhu boka.
5. Ko acrylic yakagadzirwa sei?
Polymethyl methacrylate inogadzirwa kuburikidza nepolymerization sezvo iri imwe yemapolymer ekugadzira. Chekutanga, methyl methacrylate inoiswa mu mold uye catalyst inowedzerwa kuti ikurumidze kuita. Nekuda kweiyi polymerization maitiro, PMMA inogona kuumbwa kuita akasiyana siyana semashiti, resin, mabhuraki, uye mabheji. Acrylic glue inogonawo kubatsira kupfavisa zvidimbu zvePMMA nekuzvibatanidza pamwechete.
PMMA iri nyore kushandisa nenzira dzakasiyana. Inogona kubatanidzwa nezvimwe zvinhu kuti zvibatsire kusimudzira zvimiro zvayo. Ne thermoforming, inoshanduka kana ichipisa uye inoomesa kana yatonhodzwa. Inogona kuve yakakura zvakakodzera uchishandisa saha kana laser yekucheka. Kana yakakwenenzverwa, unogona kubvisa zvikwambo kubva pamusoro uye kubatsira kuchengetedza kuvimbika kwayo.
6. Ndezvipi zvakasiyana-siyana zve acrylic?
Mhando mbiri huru dze acrylic plastiki dzakakandwa acrylic uye extruded acrylic. Cast acrylic inodhura kugadzira asi ine simba riri nani, kusimba, kujeka, thermoforming renji uye kugadzikana pane extruded acrylic. Cast acrylic inopa yakanakisa makemikari kuramba uye kusimba, uye iri nyore kuisa ruvara uye kuumbwa panguva yekugadzira maitiro. Cast acrylic inowanikwawo mune dzakasiyana siyana. Extruded acrylic ine mari yakawanda kupfuura cast acrylic uye inopa inowirirana, inoshanda acrylic pane cast acrylic (pamutengo wesimba rakaderedzwa). Extruded acrylic iri nyore kugadzira uye muchina, zvichiita kuti ive yakanakisa imwe nzira kune egirazi mashizha mumashandisirwo.
7. Sei acrylic achinyanya kushandiswa?
Acrylic inowanzoshandiswa nekuti ine hunhu hunobatsira segirazi, asi pasina brittleness nyaya. Acrylic girazi ine yakanakisa optical zvivakwa uye ine yakafanana refractive index segirazi mune yakasimba mamiriro. Nekuda kwehunhu hwayo husingaputsike, vagadziri vanogona kushandisa acrylics munzvimbo idzo girazi ringave nengozi zvakanyanya kana kuti ringakundikana (senge submarine periscopes, mahwindo endege, nezvimwewo). Semuenzaniso, iyo yakajairika fomu yegirazi isina bullet chidimbu che 1/4-inch-chimedu che acrylic, chinonzi solid acrylic. Acrylic inoitawo zvakanaka mukuumbwa kwejekiseni uye inogona kuumbwa kuita chero chimiro chinogona kugadzira mold. Simba regirazi re acrylic rakasanganiswa nekureruka kwekugadzirisa uye machining rinoita kuti rive chinhu chakanakisa, chinotsanangura chikonzero nei ichishandiswa zvakanyanya mumaindasitiri evatengi uye ekutengesa.
