An sabunta ta Nuwamba 2, 2022
Anan shine cibiyar labarai ta masana'antar gyaran allura ta Baiyear.Bayan haka, Baiyear zai raba tsarin yin gyare-gyaren allura zuwa labarai da yawa don gabatar da nazarin albarkatun kayan aikin gyaran allura, saboda akwai abun ciki da yawa.Na gaba shine labarin na biyu.
(3).SA (SAN-styrene-acrylonitrile copolymer/Dali manne)
1. Aikin SA:
Sinadarai da Kayayyakin Jiki: SA abu ne mai wuya, bayyanannen abu wanda ba shi da saurin fashewar damuwa na ciki.Babban fahimi, zafinta mai laushi da ƙarfin tasiri ya fi PS.Bangaren styrene yana sa SA mai wuya, m da sauƙin sarrafawa;bangaren acrylonitrile ya sa SA kemikal da kwanciyar hankali.SA yana da ƙarfin ɗaukar nauyi mai ƙarfi, juriya na amsa sinadarai, juriya na lalacewar zafi da kwanciyar hankali na geometric.
Ƙara abubuwan haɗin fiber gilashi zuwa SA na iya ƙara ƙarfi da juriya na nakasar zafi, da rage yawan haɓakar haɓakar thermal.Zazzabi mai laushi na Vicat na SA yana kusan 110 ° C.Matsakaicin zafin jiki a ƙarƙashin kaya yana kusan 100C, kuma raguwar SA shine kusan 0.3 ~ 0.7%.
2. Halayen tsarin SA:
Matsakaicin zafin jiki na SA shine gabaɗaya 200-250 °C.Kayan yana da sauƙi don ɗaukar danshi kuma yana buƙatar bushewa fiye da sa'a daya kafin aiki.Ruwansa ya ɗan yi muni fiye da na PS, don haka matsin allura shima ya ɗan fi girma (matsayin allura: 350 ~ 1300bar).Gudun allura: ana ba da shawarar allura mai sauri.Yana da kyau don sarrafa mold zafin jiki a 45-75 ℃.Gudanar da bushewa: SA yana da wasu kaddarorin hygroscopic idan an adana su da kyau.
Sharuɗɗan bushewa da aka ba da shawarar sune 80 ° C, 2 ~ 4 hours.Narke zafin jiki: 200 ~ 270 ℃.Idan ana sarrafa samfuran bango mai kauri, ana iya amfani da yanayin zafi a ƙasa da ƙananan iyaka.Don kayan da aka ƙarfafa, zafin jiki bai kamata ya wuce 60 ° C ba.Dole ne a tsara tsarin sanyaya da kyau, kamar yadda yanayin zafin jiki zai shafi bayyanar, raguwa da lankwasawa na sashi.Masu gudu da ƙofofi: Ana iya amfani da duk ƙofofin al'ada.Girman ƙofa dole ne ya zama daidai don guje wa ɗigo, tabo da ɓoyayyiya.
3. Yawan aikace-aikace na yau da kullun:
Wutar lantarki (kwasfa, gidaje, da sauransu), kayayyaki na yau da kullun (kayan dafa abinci, raka'a firiji, sansanonin TV, akwatunan kaset, da sauransu), masana'antar kera motoci (akwatunan fitila, masu nuni, fale-falen kayan aiki, da sauransu), kayan gida (wareware, abinci wukake, da sauransu) da sauransu), kayan kwalliyar marufi aminci gilashin, wuraren tace ruwa da kullin famfo.
Kayayyakin likitanci (syringes, bututun buƙatun jini, na'urorin kutsawa na koda da reactors).Kayan marufi (cosmetic case, lipstick hannayen riga, mascara hula kwalabe, iyakoki, hula sprayers da nozzles, da dai sauransu), samfura na musamman (gidajen da za a iya zubarwa, sansanonin goga da bristles, kayan kamun kifi, hakoran haƙora, ƙwanƙolin goge goge, masu riƙe alƙalami, nozzles na kayan kida. da monofilaments na shugabanci), da dai sauransu.
(4).ABS (super ba shredding manne)
1. Aikin ABS:
An haɗa ABS daga monomers guda uku, acrylonitrile, butadiene da styrene.(Kowane monomer yana da kaddarorin daban-daban: acrylonitrile yana da ƙarfi mai ƙarfi, kwanciyar hankali na thermal da kwanciyar hankali sinadarai; butadiene yana da ƙarfi da juriya mai ƙarfi; styrene yana da sauƙin sarrafawa, babban ƙare da ƙarfi mai ƙarfi. ci gaba da styrene-acrylonitrile lokaci da kuma lokaci mai tarwatsewar roba na polybutadiene.)
Daga ra'ayi na ilimin halittar jiki, ABS wani abu ne mai amorphous tare da babban ƙarfin injiniya da kuma kyawawan kaddarorin "tsauri, ƙarfi da karfe".Yana da amorphous polymer.ABS filastik aikin injiniya ne na gabaɗaya tare da nau'ikan iri da fa'idar amfani.Ana kuma kiransa "filastik-manufa na gabaɗaya" (MBS ana kiransa transparent ABS).Ruwa ya ɗan yi nauyi), ƙarancin raguwa (0.60%), daidaiton girma, kuma mai sauƙin tsari da tsari.
Kaddarorin ABS sun dogara ne akan rabon monomers uku da tsarin kwayoyin halitta a cikin matakai biyu.Wannan yana ba da damar sassauƙa mai girma a ƙirar samfura, kuma ya haifar da ɗaruruwan kayan ABS masu inganci daban-daban akan kasuwa.Wadannan daban-daban ingancin kayan bayar da daban-daban Properties kamar matsakaici zuwa high tasiri juriya, low zuwa high gama da high zafin jiki karkatarwa Properties, da dai sauransu ABS abu yana da m processability, bayyanar halaye, low creep da kyau kwarai girma kwanciyar hankali da kuma high tasiri ƙarfi.
ABS ne haske rawaya granular ko beaded opaque guduro, ba mai guba, wari, low ruwa sha, tare da mai kyau m jiki da kuma inji Properties, kamar kyau kwarai lantarki Properties, sa juriya, girma kwanciyar hankali, sinadaran juriya da surface mai sheki, da dai sauransu Kuma sauki don aiwatarwa da siffa.Rashin lahani shine juriya na yanayi, rashin juriyar zafi, da ƙonewa.
2.Process halaye na ABS
2.1 ABS yana da high hygroscopicity da danshi ji na ƙwarai.Dole ne a bushe gabaɗaya da preheated kafin yin gyare-gyare (aƙalla 2 hours a 80 ~ 90C), kuma abun ciki ya kamata a sarrafa shi a ƙasa 0.03%.
2.2 Dankin narke na guduro ABS ba shi da damuwa ga zafin jiki (bambanta da sauran resin amorphous).
Kodayake zafin allura na ABS ya ɗan fi na PS, ba zai iya samun kewayon dumama kamar PS ba, kuma ba zai iya amfani da dumama makaho don rage ɗankowar sa ba.Ana iya ƙara shi ta hanyar ƙara saurin dunƙule ko matsa lamba na allura don inganta ruwan sa.A general aiki zafin jiki ne 190-235 ℃.
2.3 Narke danko na ABS shine matsakaici, wanda ya fi na PS, HIPS, da AS, kuma ana buƙatar matsa lamba mafi girma (500 ~ 1000bar).
2.4 Abun ABS yana amfani da matsakaici da babban sauri da sauran saurin allura don cimma kyakkyawan sakamako.(Sai dai idan sifar ta kasance mai rikitarwa kuma sassan sirara-bangaren suna buƙatar saurin allura mafi girma), matsayin bututun samfurin yana da yuwuwa zuwa ɗigon iska.
2.5 ABS gyare-gyaren zafin jiki yana da girma, kuma ana daidaita yawan zafin jiki a 25-70 ° C.
Lokacin samar da samfuran da suka fi girma, yawan zafin jiki na ƙayyadaddun mold (mold na gaba) gabaɗaya yana da kusan 5°C sama da na mold mai motsi (tsawon baya).(Mold zafin jiki zai shafi ƙare na filastik sassa, ƙananan zafin jiki zai haifar da ƙananan ƙare)
2.6 ABS bai kamata ya kasance a cikin ganga mai zafi ba na dogon lokaci (ya kamata ya zama ƙasa da minti 30), in ba haka ba zai iya rushewa kuma ya juya launin rawaya.
3. Yawan aikace-aikace na yau da kullun: motoci (dashboards, ƙyanƙyasar kayan aiki, murfin dabaran, akwatunan madubi, da sauransu), firiji, kayan aiki masu ƙarfi (masu bushewar gashi, masu haɗawa, masu sarrafa abinci, masu yankan lawn, da dai sauransu), Lambobin tarho, maɓallan rubutu na rubutu. , Motocin nishadi irin su guraren wasan golf da skis na jet.
Don ci gaba, idan kuna son ƙarin sani, da fatan za a ji daɗin tuntuɓar mu.Baiyear babbar masana'anta ce ta haɓaka masana'anta na filastik, gyare-gyaren allura da sarrafa ƙarfe.Ko kuma ku ci gaba da kula da cibiyar labarai ta gidan yanar gizon mu: www.baidasy.com, za mu ci gaba da sabunta labaran ilimin da suka shafi masana'antar sarrafa allura.
