Ihlaziywe ngoNovemba 2, 2022
Nali iziko leendaba loshishino lokubumba inaliti ye-Baiyear.Okulandelayo, i-Baiyear iya kwahlula inkqubo yokubumba inaliti ibe ngamanqaku amaninzi ukwazisa uhlalutyo lwezinto ezikrwada zenkqubo yokubumba inaliti, kuba kukho umxholo omninzi kakhulu.Elilandelayo linqaku lesibini.
(3).SA (SAN-styrene-acrylonitrile copolymer/Dali glue)
1. Ukusebenza koMzantsi Afrika:
I-Chemical and Physical Properties: I-SA yimathiriyeli enzima, ecacileyo engenakukwazi ukukrazula uxinzelelo lwangaphakathi.Ukucaca okuphezulu, ubushushu bayo obuthambileyo kunye namandla empembelelo aphezulu kune-PS.Icandelo le-styrene lenza i-SA ibe nzima, icace kwaye kulula ukuyiqhuba;icandelo le-acrylonitrile lenza ukuba i-SA ibe neekhemikhali kunye ne-thermal stable.I-SA inomthamo oqinileyo wokuthwala umthwalo, ukuxhathisa ukusabela kweekhemikhali, ukuxhathisa i-thermal deformation kunye nokuzinza kwejometri.
Ukongeza izongezo zefiber yeglasi kwi-SA kunokonyusa amandla kunye nokumelana ne-thermal deformation, kunye nokunciphisa i-coefficient yokwandiswa kwe-thermal.Iqondo lobushushu leVicat lokuthambisa laseMzantsi Afrika limalunga ne-110°C.Ukushisa okuphambukayo phantsi komthwalo malunga ne-100C, kwaye i-shrinkage ye-SA i malunga ne-0.3 ~ 0.7%.
2. Iimpawu zenkqubo yoMzantsi Afrika:
Ubushushu bokusebenza kweSA ngokuqhelekileyo ngama-200-250 °C.Izinto eziphathekayo kulula ukufunxa umswakama kwaye kufuneka zomiswe ngaphezu kweyure enye ngaphambi kokucubungula.I-fluidity yayo imbi kancinane kune-PS, ngoko ke uxinzelelo lwenaliti luphezulu kancinane (uxinzelelo lwe-injection: 350 ~ 1300bar).Isantya sokutofa: Isitofu sesantya esiphezulu siyacetyiswa.Kungcono ukulawula ubushushu bomngundo kwi-45-75 ℃.I-Drying Handling: UMzantsi Afrika uneempawu zehygroscopic ukuba zigcinwe ngendlela engafanelekanga.
Iimeko zokumisa ezicetyiswayo zi-80 ° C, i-2 ~ 4 iiyure.Ubushushu obunyibilikayo: 200 ~ 270℃.Ukuba iimveliso ezinodonga olungqingqwa zisetyenzwa, amaqondo obushushu anyibilikayo angaphantsi komda osezantsi angasetyenziswa.Kwizinto eziqinisiweyo, ubushushu bokubumba akufanele budlule kwi-60 ° C.Inkqubo yokupholisa kufuneka yenziwe kakuhle, njengoko ukushisa kwesikhunta kuya kuchaphazela ngokuthe ngqo ukubonakala, ukuncipha kunye nokugoba kwenxalenye.Iimbaleki kunye namasango: Onke amasango aqhelekileyo anokusetyenziswa.Ubungakanani besango kufuneka buchaneke ukuphepha imivimbo, amabala kunye ne-voids.
3. Uluhlu oluqhelekileyo lwesicelo:
Umbane (iisokethi, izindlu, njl. njl.), izinto zemihla ngemihla (izixhobo zasekhitshini, iiyunithi zefriji, iziseko zeTV, iibhokisi zekhasethi, njl. njl.), ishishini lemoto (iibhokisi zezibane, izibonisi, iipaneli zesixhobo, njl. njl.), izinto zasendlini (itafile, ukutya iimela, njl.njl.) njl.), iglasi yokhuseleko lokupakisha izinto zokuthambisa, izindlu zokuhluza amanzi kunye namaqhina eempompo.
Iimveliso zonyango (iisirinji, iityhubhu zokuphefumla igazi, izixhobo zokungena ezintsoni kunye neereactors).Izinto zokupakisha (iimeko zokuthambisa, imikhono yemilebe, iibhotile zemascara, iikepusi, izitshizi zekepusi kunye nemilomo, njl.njl.), iimveliso ezikhethekileyo (izindlu ezilahliweyo ezilula, iziseko zebhrashi kunye neebristles, izixhobo zokuloba, amazinyo emboleko, izibambo zebrashi yamazinyo, izibambi zosiba, imilomo yesixhobo somculo. kunye ne-monofilaments yolwalathiso), njl.
(4).Iglu yeABS
1. Ukusebenza kwe-ABS:
I-ABS idityaniswe kwii-monomers ezintathu zeekhemikhali, i-acrylonitrile, i-butadiene kunye ne-styrene.(I-monomer nganye ineempawu ezahlukeneyo: i-acrylonitrile inamandla amakhulu, ukuzinza kwe-thermal kunye nokuzinza kweekhemikhali; i-butadiene inokuqina kunye nokuchasana kwempembelelo; i-styrene inokulungiswa okulula, ukugqiba okuphezulu kunye namandla aphezulu. Ii-monomers ezintathu ze-Polymerization yobuninzi ivelisa i-terpolymer enezigaba ezibini, a isigaba esiqhubekayo se-styrene-acrylonitrile kunye nesigaba esichithwayo serabha ye-polybutadiene.)
Ukusuka kwindawo yokujonga i-morphological, i-ABS yimathiriyeli ye-amorphous enamandla amakhulu omatshini kunye neempawu ezintle ezibanzi "zokuqina, ukuqina kunye nentsimbi".Yipolymer e-amorphous.I-ABS yiplastiki yenjongo yobunjineli ngokubanzi eneentlobo ngeentlobo kunye noluhlu olubanzi lokusetyenziswa.Ikwabizwa ngokuba "yiplastiki yenjongo jikelele" (MBS ibizwa ngokuba yi-ABS ecacileyo).Amanzi anzima kancinci), ukushwabana okuphantsi (0.60%), azinzile ngokomlinganiselo, kwaye kulula ukubunjwa nokuqhubekeka.
Iimpawu ze-ABS zixhomekeke ikakhulu kumlinganiselo wee-monomers ezintathu kunye nesakhiwo se-molecular kwizigaba ezibini.Oku kuvumela ukuguquguquka okukhulu kuyilo lwemveliso, kwaye kukhokelele kumakhulu ezinto ezisemgangathweni ezahlukeneyo ze-ABS kwimarike.Ezi zixhobo zomgangatho zahlukeneyo zibonelela ngeepropati ezahlukeneyo ezifana nokumelana nefuthe eliphakathi ukuya phezulu, eliphantsi ukuya phezulu kunye neempawu zokujija ubushushu obuphezulu, njl njl. Izinto ze-ABS zinokuqhubekeka okuphezulu, iimpawu zenkangeleko, ukukhahlela okuphantsi kunye nozinzo olubalaseleyo lwe-dimensional kunye namandla anempembelelo ephezulu.
I-ABS yintlaka emhlophe etyheli okanye i-beaded opaque resin, i-non-toxic, ivumba, ukufunxwa kwamanzi aphantsi, kunye neempawu ezintle zomzimba kunye noomatshini, njengeempawu ezibalaseleyo zombane, ukuxhathisa ukunxiba, ukuzinza komda, ukuxhathisa imichiza kunye neglosi yomphezulu, njl. ukucubungula kunye nokubumba.Into engalunganga kukumelana nemozulu, ukuxhathisa ubushushu, kunye nokutsha.
2.Iimpawu zenkqubo ye-ABS
2.1 I-ABS ine-hygroscopicity ephezulu kunye novakalelo lokufuma.Kufuneka yomiswe ngokupheleleyo kwaye ifudunyezwe ngaphambi kokubunjwa (ubuncinci iiyure ezi-2 kwi-80 ~ 90C), kwaye umxholo wokufuma kufuneka ulawulwe ngaphantsi kwe-0.03%.
2.2 I-viscosity enyibilikayo ye-ABS resin ayithinteli kakhulu kwiqondo lokushisa (ihluke kwezinye ii-amorphous resins).
Nangona ubushushu benaliti ye-ABS buphezulu kancinane kune-PS, ayinakuba noluhlu lokufudumeza olukhululekileyo njenge-PS, kwaye ayinakusebenzisa ukufudumeza okungaboniyo ukunciphisa i-viscosity yayo.Inokunyuswa ngokunyusa isantya se-screw okanye uxinzelelo lwenaliti ukuphucula ukumanzi kwayo.Ubushushu bokusebenza ngokubanzi yi-190-235℃.
2.3 I-melt viscosity ye-ABS iphakathi, ephezulu kune-PS, HIPS, kunye ne-AS, kunye noxinzelelo lwe-injection ephezulu (500 ~ 1000bar) iyadingeka.
2.4 Imathiriyeli ye-ABS isebenzisa isantya esiphakathi nesiphezulu kunye nezinye izantya zokutofa ukufumana iziphumo ezingcono.(Ngaphandle kokuba imilo inzima kwaye iindawo ezinodonga olucekethekileyo zifuna isantya esiphezulu sokutofa), indawo yombhobho wemveliso iqhelekile kwimivumbo yomoya.
2.5 iqondo lobushushu lokubumba i-ABS liphezulu, kwaye ubushushu balo lokungunda bulungiswa ngokubanzi kuma-25-70 °C.
Xa uvelisa iimveliso ezinkulu, ubushushu besikhunta esisisigxina (i-mold yangaphambili) ngokuqhelekileyo malunga ne-5 ° C ngaphezu kwe-mold ehambayo (i-mold yangemuva).(Iqondo lobushushu lokungunda liya kuchaphazela ukugqiba kwamalungu eplastiki, ubushushu obuphantsi bunokubangela ukugqiba okuphantsi)
I-2.6 i-ABS ayifanele ihlale kwi-barrel ephezulu yokushisa ixesha elide (kufuneka ibe ngaphantsi kwemizuzu engama-30), ngaphandle koko iya kubola ngokulula kwaye ibe tyheli.
3. Uluhlu oluqhelekileyo lwesicelo: iimoto (iideshibhodi, iihatshi zezixhobo, izigqubuthelo zamavili, iibhokisi zesipili, njl.njl.), iifriji, izixhobo ezomeleleyo (izomisi enwele, iiblenders, iiprosesa zokutya, oomatshini bokucheba ingca, njl.njl.), iimfonomfono IiCase, iibhodi zokuchwetheza. , izithuthi zokuzonwabisa ezifana neenqwelo zegalufa kunye ne-jet skis.
Ukuqhubeka, ukuba ufuna ukwazi ngakumbi, nceda uzive ukhululekile ukuqhagamshelana nathi.I-Baiyear ngumzi-mveliso omkhulu oqukayo odibanisa ukwenziwa komngundo weplastiki, ukubumba inaliti kunye nokusetyenzwa kwentsimbi.Okanye unokuqhubeka nokunikela ingqalelo kwiziko leendaba lewebhusayithi yethu esemthethweni: www.baidasy.com, siya kuqhubeka nokuhlaziya iindaba zolwazi ezinxulumene neshishini lokulungisa inaliti.
