NaAndy anobva kuBaiyear fekitori
Yakadzorerwa November 2, 2022
Heino nzvimbo yenhau yeBaiyear's injection molding industry.Tevere, Baiyear ichakamura jekiseni rekuumba kuita zvinyorwa zvakati wandei kusuma ongororo yezvakagadzirwa zvejekiseni rekuumba maitiro, nekuti kune zvakawanda zvirimo.Chinotevera chinyorwa chechipiri.
(3).SA (SAN-styrene-acrylonitrile copolymer/Dali guruu)
1. Kuita kweSA:
Chemical and Physical Properties: SA chinhu chakaoma, chakajeka chisingaenderane nekushushikana kwemukati kutsemuka.Kujeka kwepamusoro, kupisa kwayo kunyorova uye simba rekuita zvakakwirira kupfuura PS.Iyo styrene chikamu chinoita kuti SA yakaoma, yakajeka uye iri nyore kugadzirisa;iyo acrylonitrile chikamu chinoita kuti SA makemikari uye thermally kugadzikana.SA ine simba rekutakura mutoro wakasimba, makemikari anoita kuramba, thermal deformation resistance uye geometric stability.
Kuwedzera girazi fiber additives kuSA kunogona kuwedzera simba uye kupisa deformation kuramba, uye kuderedza kupisa kwekuwedzera coefficient.The Vicat softening tembiricha yeSA inenge 110°C.Iyo tembiricha yekutsauka pasi pemutoro inenge 100C, uye shrinkage yeSA inenge 0.3 ~ 0.7%.
2. Maitiro maitiro eSA:
Iyo tembiricha yekugadzirisa yeSA inowanzo 200-250 ° C.Izvo zvinhu zviri nyore kutora unyoro uye zvinoda kuomeswa kweinopfuura awa imwe isati yagadziriswa.Kunyungudika kwayo kwakashata zvishoma kupfuura kwePS, saka kudzvanywa kwejekiseni zvakare kwakakwira zvishoma (jekiseni kudzvanywa: 350 ~ 1300bar).Injection speed: high-speed jekiseni inokurudzirwa.Zviri nani kudzora tembiricha yekuumbwa pa45-75 ℃.Drying Handling: SA ine zvimwe hygroscopic zvivakwa kana zvakachengetwa zvisina kunaka.
Iyo inokurudzirwa kuomeswa mamiriro i80 ° C, 2 ~ 4 maawa.Kunyunguduka tembiricha: 200 ~ 270 ℃.Kana zvigadzirwa zvakakora-madziro zvakagadziriswa, tembiricha yekunyunguduka iri pasi pemuganho wakaderera inogona kushandiswa.Pazvinhu zvakasimbiswa, tembiricha yekuumbwa haifanire kudarika 60 ° C.Iyo yekutonhodza sisitimu inofanirwa kuve yakagadzirwa zvakanaka, sezvo tembiricha yekuumbwa ichakanganisa zvakananga kutaridzika, shrinkage uye kukotama kwechikamu.Vanomhanya nemasuwo: Magedhi ese akajairwa anogona kushandiswa.Saizi yegedhi inofanirwa kuve yakarurama kudzivirira mitsetse, mavara uye voids.
3. Yakajairika application range:
Magetsi (zvigadziko, dzimba, nezvimwewo), zvinhu zvezuva nezuva (midziyo yemukicheni, mafiriji mayunitsi, mabhesi eTV, mabhokisi emakaseti, nezvimwewo), indasitiri yemotokari (mabhokisi emwenje, zviratidziro, mapaneru, nezvimwewo), zvinhu zvemumba (tableware, chikafu. mapanga, nezvimwewo) zvichingodaro), girazi rekuchengetedza zvekushongedza, dzimba dzemasefa emvura uye mapfundo epombi.
Zvigadzirwa zvekurapa (majekiseni, machubhu ekushuvira ropa, midziyo yekupinza renal uye mareactor).Packaging zvinhu (cosmetic makesi, lipstick sleeve, mascara cap mabhodhoro, caps, cap sprayers uye nozzles, etc.), zvigadzirwa zvehunyanzvi (kuraswa zvimba, mabhesi ebhurashi uye bristles, giya rehove, mazino, zvibatiso zvebhurasho, zvibatiso, zvibatiso zvezviridzwa zvemimhanzi. uye inotungamira monofilaments), nezvimwe.
(4).ABS (super non-shredding glue)
1. ABS kuita:
ABS inogadzirwa kubva kumatatu emakemikari monomers, acrylonitrile, butadiene uye styrene.(Monomer imwe neimwe ine zvakasiyana-siyana: acrylonitrile ine simba guru, kugadzikana kwekupisa uye kugadzikana kwemakemikari; butadiene ine kuoma uye kupikisa; styrene ine nyore kugadzirisa, kupera kwepamusoro uye simba guru. Matatu monomers Polymerization yehuwandu inobudisa terpolymer ine zvikamu zviviri, a inoenderera mberi styrene-acrylonitrile chikamu uye polybutadiene rubber yakapararira chikamu.)
Kubva pane morphological point yekuona, ABS ndeye amorphous zvinhu zvine yakakwira mechaniki simba uye yakanaka yakazara midziyo ye "kuoma, kusimba uye simbi".Iyo inonzi amorphous polymer.ABS ipurasitiki-yechinangwa cheinjiniya ine marudzi akasiyana-siyana uye kushandiswa kwakasiyana-siyana.Inonzi zvakare "general-purpose plastic" (MBS inonzi transparent ABS).Mvura inorema zvishoma), yakaderera shrinkage (0.60%), yakagadzikana, uye iri nyore kugadzira nekugadzirisa.
Izvo zvimiro zveABS zvinonyanya kutsamira pachiyero chevatatu monomers uye chimiro chemolecular muzvikamu zviviri izvi.Izvi zvinobvumira kushanduka kukuru mukugadzirwa kwechigadzirwa, uye zvakakonzera mazana emhando dzakasiyana dzeABS zvinhu pamusika.Izvi zvakasiyana-siyana zvemhando zvinhu zvinopa zvinhu zvakasiyana-siyana zvakadai sepakati kusvika kune yakakwirira simba rekudzivirira, yakaderera kusvika pakukwirira kwepamusoro uye yakakwirira tembiricha inomonyorora zvivakwa, etc. ABS zvinhu zvine hunyanzvi hwekugadzirisa, maitiro ekutaridzika, kudzika kwakadzika uye kugadzikana kwechimiro uye kusimba kwepamusoro.
ABS yakareruka yeyero granular kana beaded opaque resin, isina-chepfu, haina kunhuhwirira, yakadzika mvura yekunyudza, ine yakanaka yakazara yemuviri uye michina zvimiro, senge yakanakisa magetsi emagetsi, kupfeka kuramba, kugadzikana kwedimensional, makemikari kuramba uye kupenya kwepasi, nezvimwe. Uye zviri nyore. kugadzirisa uye kuumba.Izvo zvinokanganisa kusamira kwemamiriro ekunze, kushomeka kwekupisa, uye kupisa.
2.Process maitiro eABS
2.1 ABS ine yakakwira hygroscopicity uye hunyoro hwekunzwa.Inofanira kuomeswa zvakakwana uye preheated isati yaumbwa (inenge maawa maviri pa80 ~ 90C), uye hunyoro hunofanira kudzorwa pasi pe0.03%.
2.2 Iyo yakanyunguduka viscosity yeABS resin isinganyanyi kunzwa tembiricha (yakasiyana nemamwe amorphous resins).
Kunyangwe iyo tembiricha yejekiseni yeABS yakakwira zvishoma pane iyo yePS, haigone kuve yakasununguka yekudziya renji sePS, uye haigone kushandisa kudziyisa bofu kuderedza viscosity yayo.Inogona kuwedzerwa nekuwedzera screw speed kana jekiseni pressure kuti ivandudze fluidity yayo.Iyo yakawanda yekugadzirisa tembiricha ndeye 190-235 ℃.
2.3 The melt viscosity yeABS ndeyepakati, iyo yakakwirira kudarika yePS, HIPS, uye AS, uye yakakwirira jekiseni pressure (500 ~ 1000bar) inodiwa.
2.4 ABS zvinhu zvinoshandisa zviri pakati nepakati nekumhanya uye kumwe kumhanya kwejekiseni kuti uwane mhedzisiro iri nani.(Kunze kwekunge chimiro chakaomarara uye dzakatetepa-madziro mativi anoda yakakwirira jekiseni kumhanya), chigadzirwa nozzle chinzvimbo chinotarirwa kumhepo mitsetse.
2.5 ABS yekuumba tembiricha yakakwira, uye tembiricha yayo mold inowanzogadziriswa pa25-70 °C.
Paunenge uchigadzira zvigadzirwa zvakakura, tembiricha yeyakagadziriswa mold (yekumberi mold) kazhinji inenge 5 ° C yakakwirira kupfuura iyo inofambiswa mold (kumashure mold).(Kupisa kwe mold kunokanganisa kupera kwezvikamu zvepurasitiki, tembiricha yakadzika inoguma nekupera kwakadzika)
2.6 ABS haifanire kugara mugomba rekushisa kwepamusoro kwenguva yakareba (inofanira kunge isingasviki maminetsi makumi matatu), kana zvisina kudaro inoora nyore uye ichiita yero.
3. Yakajairika mashandisirwo emhando: mota (madhibhodhi, machira ezvishandiso, zvivharo zvemavhiri, mabhokisi egirazi, nezvimwewo), mafiriji, maturusi ane simba guru (magadzirirwo ebvudzi, mablender, magadzirirwo echikafu, lawn mowers, nezvimwewo), nhare Case, tapureta kiyibhodhi. , mota dzekuvaraidza dzakadai sengoro dzegorofu uye jet skis.
Kuenderera mberi, kana uchida kuziva zvakawanda, ndapota inzwa wakasununguka kutibata nesu.Baiyear ifekitari yakakura yakazara yakazara inobatanidza kugadzira epurasitiki mold, jekiseni rekugadzira uye sheet simbi kugadzirisa.Kana kuti iwe unogona kuramba uchiteerera kune nzvimbo yenhau yewebhusaiti yedu yepamutemo: www.baidasy.com, isu ticharamba tichivandudza ruzivo rwenhau dzine chekuita nejekiseni molding processing industry.
