- AS
1. AS ukusebenza
I-AS yipropylene-styrene copolymer, ekwabizwa ngokuba yi-SAN, enoxinano malunga ne-1.07g/cm3. Ayiqhelekanga ukuqhekeka koxinzelelo lwangaphakathi. Inokukhanya okuphezulu okuphezulu, ubushushu obuphezulu bokuthambisa kunye namandla empembelelo kune-PS, kunye nokumelana nokudinwa okuphantsi.
2. Ukusetyenziswa kwe-AS
Iitreyi, iikomityi, izixhobo zetafile, iikhompatimenti zefriji, amaqhina, izixhobo zokukhanyisa, izihombiso, izipili zesixhobo, iibhokisi zokupakisha, izinto zokubhala, izibane zegesi, izibambo zebrashi yamazinyo, njl.
3. Iimeko zokusetyenzwa kwe-AS
Ubushushu bokusebenza be-AS buqhele ukuba ngama-210 ~ 250℃. Esi sixhobo kulula ukufunxa ukufuma kwaye kufuneka somiswe ngaphezu kweyure enye ngaphambi kokuba kuqhutywe. Ubumanzi bayo bubi kancinci kune-PS, ngoko ke uxinzelelo lwenaliti luphezulu kancinci, kwaye ubushushu bokubumba bulawulwa kwi-45 ~ 75 ℃ ngcono.
- ABS
1. Ukusebenza kwe-ABS
I-ABS yi-acrylonitrile-butadiene-styrene terpolymer. Yipolymer e-amorphous enoxinano malunga ne-1.05g/cm3. Inamandla omatshini aphezulu kunye neepropathi ezilungileyo ezibanzi ze "nkqo, eqinile kunye nentsimbi". I-ABS yiplastiki yobunjineli esetyenziswa ngokubanzi eneentlobo ezahlukeneyo kunye nokusetyenziswa okubanzi. Ikwabizwa ngokuba "yiplastiki yobunjineli ngokubanzi" (i-MBS ibizwa ngokuba yi-ABS ecacileyo). Kulula ukumila kunye nokusebenza, inokumelana nekhemikhali engalunganga, kwaye iimveliso zilula ukuba zifakwe kwi-electroplated.
2. Ukusetyenziswa kwe-ABS
Iimpompo zeempompo, iibheringi, izibambo, imibhobho, iicasing zesixhobo sombane, iinxalenye zemveliso ye-elektroniki, iithoyi, iikesi zokubukela, izixhobo zesixhobo, iikhaseji zetanki zamanzi, ugcino olubandayo kunye neecasing zangaphakathi zefriji.
3. Iimpawu zenkqubo ye-ABS
(1) I-ABS ine-hygroscopicity ephezulu kunye nokumelana nobushushu obuphantsi. Kufuneka yomiswe ngokupheleleyo kwaye ifudunyezwe phambi kokuba ibunjwe kwaye ilungiswe ukulawula ukufuma okungaphantsi kwe-0.03%.
(2) I-viscosity enyibilikayo ye-ABS resin ayinabungozi kakhulu kwiqondo lokushisa (ihluke kwezinye iireyini ze-amorphous). Nangona iqondo lobushushu benaliti ye-ABS liphezulu kancinci kunolo lwe-PS, ayinalo ubushushu obunyukayo obufana ne-PS, kwaye ukufudumeza okungaboniyo akunakusetyenziswa. Ukunciphisa i-viscosity yayo, unokunyusa isantya se-screw okanye unyuse uxinzelelo lwenaliti / isantya sokuphucula ukumanzi kwayo. Ubushushu bokusebenza ngokubanzi yi-190 ~ 235℃.
(3) I-melt viscosity ye-ABS iphakathi, iphezulu kune-PS, i-HIPS, kunye ne-AS, kwaye i-fluidity yayo ihlwempuzekileyo, ngoko ke uxinzelelo oluphezulu lwenaliti luyafuneka.
(4) I-ABS inesiphumo esihle kunye nesantya senaliti esiphakathi ukuya esiphakathi (ngaphandle kokuba iimilo ezintsonkothileyo kunye namalungu amancinci afuna isantya esiphezulu sokutofa), umlomo wemveliso uthambekele kumanqaku omoya.
5 Xa uvelisa iimveliso ezinkulu, ubushushu besikhunta esisisigxina (i-mold yangaphambili) ngokuqhelekileyo malunga ne-5 ° C ngaphezu kwe-mold ehambayo (i-mold yangemuva).
(6) I-ABS ayifanele ihlale kwi-barrel yobushushu obuphezulu ixesha elide (kufuneka ibe ngaphantsi kwemizuzu engama-30), kungenjalo iya kubola ngokulula kwaye ijike ibe tyheli.
- PMMA
1. Ukusebenza kwe-PMMA
I-PMMA yipolymer e-amorphous, eyaziwa ngokuba yi-plexiglass (i-sub-acrylic), kunye noxinano malunga ne-1.18g / cm3. Inokukhanya okugqwesileyo kunye nokuhanjiswa kokukhanya kwe-92%. Yimpahla elungileyo ye-optical; inokumelana nobushushu obuhle (ukumelana nobushushu). Ubushushu be-deformation yi-98 ° C). Imveliso yayo inamandla omatshini aphakathi kunye nobunzima obuphantsi komhlaba. Ikrwelwa ngokulula ngezinto eziqinileyo kwaye ishiya umkhondo. Xa kuthelekiswa ne-PS, akukho lula ukuba brittle.
2. Ukusetyenziswa kwe-PMMA
Iilensi zesixhobo, iimveliso zamehlo, izixhobo zombane, izixhobo zonyango, iimodeli ezicacileyo, imihombiso, iilensi zelanga, amazinyo emboleko, iibhodi zebhodi, iipaneli zewotshi, izibane zemoto, ii-windshields, njl.
3. Iimpawu zenkqubo ye-PMMA
Iimfuno zokusetyenzwa kwe-PMMA zingqongqo. Inochuku kakhulu kumswakama kunye nobushushu. Kufuneka yomiswe ngokupheleleyo phambi kokulungiswa. I-viscosity yayo yokunyibilika iphezulu, ngoko ke kufuneka ibunjwe kubushushu obuphezulu (219 ~ 240 ℃) kunye noxinzelelo. Ubushushu bomngundo buphakathi kwe 65~ 80℃ bungcono. Ukuzinza kwe-thermal ye-PMMA akulunganga kakhulu. Iya kuthotywa ngubushushu obuphezulu okanye ihlale kwiqondo lobushushu eliphezulu ixesha elide. Isantya sokujiya akufunekanga sibe phezulu kakhulu (malunga ne-60rpm), njengoko kulula ukwenzeka kwiindawo ezityebileyo ze-PMMA. Into "engenanto" ifuna amasango amakhulu kunye "nobushushu obuphezulu bezinto eziphathekayo, ubushushu obuphezulu besikhunta, isantya esicothayo" iimeko zokutofa ukuze kuqhutywe.
4. Yintoni i-acrylic (PMMA)?
I-Acrylic (PMMA) yiplastiki ecacileyo, eqinile ehlala isetyenziswa endaweni yeglasi kwiimveliso ezifana neefestile eziqhekezayo, iimpawu ezikhanyayo, ukukhanya kwesibhakabhaka kunye neekhenopi zeenqwelo-moya. I-PMMA yeyentsapho ebalulekileyo ye-acrylic resins. Igama lekhemikhali ye-acrylic yi-polymethyl methacrylate (PMMA), eyi-resin yokwenziwa epholymerized ukusuka kwi-methyl methacrylate.
I-Polymethylmethacrylate (PMMA) ikwabizwa ngokuba yi-acrylic, iglasi ye-acrylic, kwaye iyafumaneka phantsi kwamagama orhwebo kunye neempawu ezifana ne-Crylux, i-Plexiglas, i-Acrylite, i-Perclax, i-Astariglas, i-Lucite, kunye ne-Perspex, phakathi kwabanye. I-Polymethylmethacrylate (PMMA) isoloko isetyenziswa kwifom yephepha njengento ekhaphukhaphu okanye engayitshatterproof kwiglasi. I-PMMA ikwasetyenziswa njenge-resin yokuphosa, i-inki, kunye nokwaleka. I-PMMA yinxalenye yeqela lezinto zeplastiki zobunjineli.
5. Yenziwa njani i-acrylic?
I-polymethyl methacrylate yenziwa ngepolymerization njengoko iyenye yeepolima zokwenziwa. Okokuqala, i-methyl methacrylate ifakwe kwi-mold kwaye i-catalyst yongezwa ukukhawulezisa inkqubo. Ngenxa yale nkqubo ye-polymerization, i-PMMA inokubunjwa kwiifom ezahlukeneyo ezifana namaphepha, iireyini, iibhloko, kunye namaso. Iglu ye-Acrylic inokunceda ukuthambisa iziqwenga ze-PMMA kwaye zidibanise.
I-PMMA kulula ukuyilawula ngeendlela ezahlukeneyo. Inokudityaniswa nezinye izinto ukunceda ukuphucula iimpawu zayo. Nge-thermoforming, iba bhetyebhetye xa ishushu kwaye iqina xa ipholile. Inokulinganiswa ngokufanelekileyo kusetyenziswa isarha okanye ukusika i-laser. Ukuba uphuculwe, unokususa imikrwelo kumphezulu kwaye uncede ukugcina ingqibelelo yayo.
6. Ziziphi iintlobo ezahlukeneyo ze-acrylic?
Iintlobo ezimbini eziphambili zeplastiki ye-acrylic zenziwe nge-acrylic kunye ne-acrylic extruded. I-acrylic yokuphosa kubiza kakhulu ukuvelisa kodwa inamandla angcono, ukuqina, ukucaca, uluhlu lwe-thermoforming kunye nozinzo kune-acrylic ekhutshiweyo. I-acrylic ye-Cast inika ukuxhathisa kweekhemikhali okugqwesileyo kunye nokuqina, kwaye kulula ukufaka umbala kunye nokumila ngexesha lenkqubo yokuvelisa. I-acrylic yokuphosa iyafumaneka kwiindidi ezahlukeneyo zobunzima. I-acrylic eyongeziweyo inoqoqosho ngakumbi kune-acrylic etyhidiweyo kwaye inikezela ngokuhambelana ngakumbi, i-acrylic esebenzayo kune-acrylic ephosiweyo (ngeendleko zokunciphisa amandla). I-acrylic eyongeziweyo kulula ukuyiqhuba kunye nomatshini, iyenza ibe yeyona ndlela ibalaseleyo kumaphepha eglasi kwizicelo.
7. Kutheni i-acrylic isetyenziswa ngokuqhelekileyo?
I-Acrylic isoloko isetyenziswa ngenxa yokuba ineempawu ezifanayo ezinenzuzo njengeglasi, kodwa ngaphandle kwemiba ye-brittleness. Iglasi ye-Acrylic ineempawu ezibalaseleyo ze-optical kwaye inesalathiso se-refractive esifanayo njengeglasi kwimeko eqinileyo. Ngenxa yeempawu zayo ezinqabileyo, abaqulunqi banokusebenzisa i-acrylics kwiindawo apho iglasi iya kuba yingozi kakhulu okanye ingaphumeleli (njenge-submarine periscopes, iifestile zeenqwelomoya, njl. njl.). Ngokomzekelo, eyona ndlela iqhelekileyo yeglasi ye-bulletproof yi-1/4-inch-thick piece ye-acrylic, ebizwa ngokuba yi-acrylic eqinile. I-Acrylic iphinda isebenze kakuhle ekubumbeni inaliti kwaye inokubunjwa phantse kuyo nayiphi na imilo enokwenziwa ngumenzi. Amandla eglasi ye-acrylic edityaniswe nokulula kwayo ukulungiswa kunye nomatshini kuyenza ibe yinto ebalaseleyo, echaza ukuba kutheni isetyenziswa ngokubanzi kumashishini abathengi kunye nezorhwebo.
