Wolemba Andy wochokera ku fakitale ya Baiyear
Idasinthidwa Novembala 2, 2022
Nawa likulu la nkhani zamakampani opanga jakisoni a Baiyear.Kenako, Baiyear agawa njira yopangira jekeseni muzolemba zingapo kuti adziwe kusanthula kwa zida zopangira jekeseni, chifukwa pali zambiri.Chotsatira ndi nkhani yachiwiri.
(3).SA (SAN-styrene-acrylonitrile copolymer/Dali guluu)
1. Kachitidwe ka SA:
Chemical and Physical Properties: SA ndi chinthu cholimba, chowonekera chomwe sichimakonda kusweka kwamkati.Kuwonekera kwakukulu, kutentha kwake kofewetsa ndi mphamvu zake ndizokwera kuposa PS.Chigawo cha styrene chimapangitsa SA kukhala yovuta, yowonekera komanso yosavuta kukonza;chigawo cha acrylonitrile chimapangitsa SA kukhazikika kwa mankhwala ndi thermally.SA ili ndi mphamvu yonyamula katundu, kukana kwa mankhwala, kukana kwa kutentha kwa kutentha ndi kukhazikika kwa geometric.
Kuonjezera zowonjezera zowonjezera zamagalasi ku SA kumatha kukulitsa mphamvu ndi kukana kusinthika kwamafuta, ndikuchepetsa kukulitsa kwamafuta.The Vicat softening kutentha kwa SA ndi pafupifupi 110°C.Kutentha kwapang'onopang'ono pansi pa katundu ndi pafupifupi 100C, ndipo kuchepa kwa SA kuli pafupifupi 0.3 ~ 0.7%.
2. Zochita za SA:
Kutentha kwa SA nthawi zambiri kumakhala 200-250 ° C.Zinthuzi ndizosavuta kuyamwa chinyezi ndipo zimafunika kuumitsa kwa ola limodzi musanakonze.Kuthamanga kwake kumakhala koyipa pang'ono kuposa kwa PS, kotero kuthamanga kwa jakisoni nakonso kumakwera pang'ono (kuthamanga kwa jekeseni: 350 ~ 1300bar).Kuthamanga kwa jekeseni: jekeseni wothamanga kwambiri akulimbikitsidwa.Ndi bwino kulamulira nkhungu kutentha pa 45-75 ℃.Drying Handling: SA ili ndi zinthu zina za hygroscopic ngati zasungidwa molakwika.
Kuwumitsa kovomerezeka ndi 80 ° C, 2 ~ 4 hours.Kutentha kwapakati: 200 ~ 270 ℃.Ngati mankhwala opangidwa ndi mipanda yokhuthala akonzedwa, kutentha kosungunuka pansi pa malire otsika kungagwiritsidwe ntchito.Pazinthu zolimbitsa, kutentha kwa nkhungu sikuyenera kupitirira 60 ° C.Dongosolo lozizira liyenera kupangidwa bwino, chifukwa kutentha kwa nkhungu kumakhudza mwachindunji mawonekedwe, kuchepa ndi kupindika kwa gawolo.Othamanga ndi zipata: Zipata zonse wamba zitha kugwiritsidwa ntchito.Kukula kwa chipata kuyenera kukhala koyenera kuti tipewe mikwingwirima, mawanga ndi voids.
3. Magwiritsidwe osiyanasiyana:
Zamagetsi (sockets, housings, etc.), zinthu zatsiku ndi tsiku (zida za m’khichini, firiji, ma TV, mabokosi a makaseti, ndi zina zotero), makampani opanga magalimoto (mabokosi a nyali, zowunikira, mapanelo a zida, etc.), zinthu zapakhomo (tableware, chakudya mipeni, etc.) etc.), galasi chitetezo zodzikongoletsera, nyumba zosefera madzi ndi mfundo za faucet.
Zinthu zachipatala (masyringe, machubu otulutsa magazi, zida zolowetsa aimpso ndi ma reactor).Zida zopakira (zodzikongoletsera, manja a lipstick, mabotolo a mascara, zisoti, zopopera ndi zotsekemera, ndi zina), zinthu zapadera (zinyumba zopepuka zotayira, maburashi ndi bristles, zida zophera nsomba, mano opangira mano, zogwirira mswachi, zolembera, zida zoimbira ndi ma monofilaments otsogolera), etc.
(4).ABS (guluu wapamwamba wosang'amba)
1. Kuchita kwa ABS:
ABS imapangidwa kuchokera ku ma monomer atatu amankhwala, acrylonitrile, butadiene ndi styrene.(Monomer iliyonse ili ndi katundu wosiyana: acrylonitrile ali ndi mphamvu zambiri, kukhazikika kwa kutentha ndi kukhazikika kwa mankhwala; butadiene imakhala ndi kulimba komanso kukana; styrene imakhala yosavuta, yomaliza komanso yolimba kwambiri. Ma monomers atatu Polymerization ya chochuluka imapanga terpolymer ndi magawo awiri, a mosalekeza styrene-acrylonitrile gawo ndi polybutadiene rabara omwazikana gawo.)
Kuchokera pamawonedwe a morphological, ABS ndi chinthu cha amorphous chokhala ndi mphamvu zamakina apamwamba komanso zinthu zambiri za "kulimba, kulimba ndi chitsulo".Ndi polima amorphous.ABS ndi pulasitiki yaukadaulo yogwiritsidwa ntchito ndi mitundu yosiyanasiyana komanso yogwiritsidwa ntchito mosiyanasiyana.Imatchedwanso "pulasitiki-cholinga chonse" (MBS imatchedwa transparent ABS).Madzi ndi olemera pang'ono), kuchepa pang'ono (0.60%), osasunthika, komanso osavuta kupanga ndi kukonza.
Makhalidwe a ABS makamaka amadalira chiŵerengero cha ma monomers atatu ndi kapangidwe ka maselo mu magawo awiriwa.Izi zimathandiza kusinthasintha kwakukulu pamapangidwe azinthu, ndipo zapangitsa kuti pakhale mazana amitundu yosiyanasiyana ya ABS pamsika.Izi zosiyanasiyana khalidwe zipangizo kupereka katundu zosiyanasiyana monga sing'anga ndi mkulu kukana kukhudza, otsika mpaka mkulu mapeto ndi mkulu kutentha kupindika katundu, etc. ABS zakuthupi ali apamwamba processability, maonekedwe maonekedwe, otsika amakwawa ndi kwambiri dimensional bata ndi mkulu zotsatira mphamvu.
ABS ndi kuwala chikasu granular kapena beaded opaque utomoni, sanali poizoni, odorless, otsika madzi mayamwidwe, ndi zabwino mabuku thupi ndi makina katundu, monga kwambiri magetsi katundu, kukana kuvala, dimensional bata, kukana mankhwala ndi pamwamba gloss, etc. Ndipo zosavuta kukonza ndi kupanga.Choyipa chake ndi kukana kwanyengo, kusamva bwino kwa kutentha, komanso kupsa.
2.Makhalidwe a ndondomeko ya ABS
2.1 ABS ili ndi hygroscopicity yayikulu komanso kumva chinyezi.Iyenera kuuma kwathunthu ndikutenthedwa musanawumbe (osachepera maola 2 pa 80 ~ 90C), ndipo chinyezi chiyenera kuyendetsedwa pansi pa 0.03%.
2.2 The viscosity yosungunuka ya ABS resin imakhala yochepa kwambiri ndi kutentha (yosiyana ndi ma resins ena amorphous).
Ngakhale kutentha kwa jakisoni wa ABS ndikokwera pang'ono kuposa kwa PS, sikungakhale ndi kutentha kotayirira ngati PS, ndipo sikungagwiritse ntchito kutentha kwakhungu kuti muchepetse kukhuthala kwake.Itha kuchulukitsidwa powonjezera liwiro la screw kapena kuthamanga kwa jakisoni kuti ipititse patsogolo madzi ake.Ambiri processing kutentha ndi 190-235 ℃.
2.3 The viscosity yosungunuka ya ABS ndi yapakatikati, yomwe ndi yapamwamba kuposa ya PS, HIPS, ndi AS, ndipo kuthamanga kwa jekeseni wapamwamba (500 ~ 1000bar) kumafunika.
Zinthu za 2.4 ABS zimagwiritsa ntchito liwiro lapakati komanso lalitali komanso kuthamanga kwina kwa jakisoni kuti akwaniritse zotsatira zabwino.(Pokhapokha ngati mawonekedwewo ndi ovuta komanso mbali zowonda-mipanda zimafuna kuthamanga kwa jekeseni), malo opangira jekeseni amatha kukhala ndi mikwingwirima ya mpweya.
2.5 ABS akamaumba kutentha ndi mkulu, ndi nkhungu kutentha ake zambiri kusintha pa 25-70 °C.
Popanga zinthu zazikulu, kutentha kwa nkhungu yokhazikika (chikombole chakutsogolo) nthawi zambiri chimakhala cha 5 ° C kuposa cha nkhungu yosunthika (kumbuyo yakumbuyo).(Kutentha kwa nkhungu kumakhudza mapeto a zigawo za pulasitiki, kutentha kochepa kumapangitsa kuti pakhale kutsika)
2.6 ABS sayenera kukhala mu mbiya yotentha kwambiri (iyenera kukhala yosachepera mphindi 30), apo ayi imatha kuwola ndikutembenukira chikasu.
3. Mitundu yofananira yogwiritsira ntchito: magalimoto (ma dashboard, ma hatchi a zida, zovundikira mawilo, mabokosi agalasi, ndi zina zambiri), mafiriji, zida zamphamvu kwambiri (zowumitsira tsitsi, zophatikizira, makina opangira chakudya, zotchetchera kapinga, ndi zina zambiri), mafoni Makaseti, makina ojambulira , magalimoto osangalatsa monga ngolo za gofu ndi ma jeti otsetsereka.
Kuti mupitilize, ngati mukufuna kudziwa zambiri, chonde omasuka kulumikizana nafe.Baiyear ndi fakitale yayikulu yophatikiza kupanga nkhungu ya pulasitiki, jekeseni ndi kukonza zitsulo.Kapena mutha kupitiliza kumvetsera nkhani zapatsamba lathu lovomerezeka: www.baidasy.com , tipitilizabe kukonzanso nkhani zachidziwitso zokhudzana ndi mafakitale opangira jekeseni.
