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 farko.
(1).PS (polystyrene)
1. Ayyukan PS:
PS shine polymer amorphous tare da ruwa mai kyau da ƙarancin sha ruwa (kasa da 00.2%).Filastik ne mai sauƙi wanda ke da sauƙin samarwa da sarrafawa.Samfuran sa suna da isar da haske na 88-92%, ƙarfi mai ƙarfi da ƙarfi.Duk da haka, samfuran PS suna da ƙarfi, masu saurin fashewar damuwa na ciki, suna da ƙarancin juriya na zafi (60-80 ° C), ba su da guba, kuma suna da takamaiman nauyi na kusan 1.04g \ cm3 (dan kadan ya fi girma fiye da ruwa).
Ƙimar gyare-gyare (darajar ita ce gabaɗaya 0.004-0.007in/in), PS m - wannan sunan kawai yana nuna gaskiyar guduro, ba crystallinity ba.(Chemical da na jiki Properties: Mafi yawan kasuwanci PSs ne m, amorphous kayan. PS yana da matukar kyau geometric kwanciyar hankali, thermal kwanciyar hankali, Tantancewar watsa Properties, lantarki insulating Properties, da kuma wani sosai kananan hali zuwa sha danshi. Yana Resistant ga ruwa, diluted inorganic acid). , amma ana iya lalata ta ta hanyar acid mai ƙarfi mai ƙarfi kamar sulfuric acid da aka tattara, kuma yana iya kumbura da lalacewa a cikin wasu kaushi na halitta.)
2. Tsarin fasali na PS:
Matsakaicin narkewa na PS shine 166 ° C, yawan zafin jiki na sarrafawa shine 185-215 ° C, kuma zafin narkewa shine 180 ~ 280 ° C.Don kayan da ke hana harshen wuta, iyakar babba ita ce 250 ° C, kuma zafin bazuwar yana da kusan 290 ° C, don haka yanayin zafin sarrafa shi yana da faɗi.
A mold zafin jiki ne 40 ~ 50 ℃, da allura matsa lamba: 200 ~ 600bar, da allura gudun bada shawarar yin amfani da sauri allura gudun, da masu gudu da ƙofofin iya amfani da duk na al'ada iri ƙofofin.Abubuwan PS yawanci ba sa buƙatar bushewa kafin sarrafawa sai dai idan ba a adana su daidai ba.Idan ana buƙatar bushewa, yanayin bushewar shawarar da aka ba da shawarar shine 80C don 2 ~ 3 hours.
Saboda ƙarancin ƙayyadaddun zafi na PS, wasu ƙira za a iya haɗa su da sauri da ƙarfi lokacin da aka sanya su don zubar da zafi.Adadin sanyaya ya fi sauri fiye da na kayan albarkatu na yau da kullun, kuma lokacin buɗewar mold na iya zama a baya.Lokacin filastik da lokacin sanyaya gajere ne, kuma za a rage lokacin sake zagayowar;da kyalkyali na PS kayayyakin ne mafi alhẽri kamar yadda mold zafin jiki ƙaruwa.
3.Typical aikace-aikace: marufi kayayyakin (kwantena, iyakoki, kwalabe), zubar da kayan aikin likita, kayan wasa, kofuna, wukake, tef reels, hadari windows da yawa kumfa kayayyakin - kwali kwali.Nama da kaji marufi trays, kwalban lakabin da kumfa PS cushioning kayan, samfur marufi, gida kayan (yanke, trays, da dai sauransu), lantarki (m kwantena, haske diffusers, insulating fina-finai, da dai sauransu).
(2).HIPS (gyara polystyrene)
1. Ayyukan HIPS:
HIPS abu ne da aka gyara na PS.Ya ƙunshi kashi 5-15% na roba a cikin kwayoyin halitta.Ƙarfinsa yana kusan sau huɗu fiye da na PS, kuma ƙarfin tasirinsa yana inganta sosai (high tasiri polystyrene).Yana da darajar retardant na harshen wuta da juriya mai tsauri.maki, high sheki maki, musamman high tasiri ƙarfi maki, gilashin fiber ƙarfafa maki, da ƙananan saura maras tabbas maki.
Sauran mahimman kaddarorin daidaitattun HIPS: ƙarfin lanƙwasa 13.8-55.1MPa;Ƙarfin ƙarfi 13.8-41.4MPa;elongation a karya 15-75%;yawa 1.035-1.04 g / ml;Abubuwan amfani.Labaran HIPS ba su da kyan gani.HIPS yana da ƙarancin sha ruwa kuma ana iya sarrafa shi ba tare da bushewa ba.
2. Hanyoyin aiwatar da HIPS:
Domin kwayoyin HIPS ya ƙunshi 5-15% roba, wanda ke shafar yawan ruwa zuwa wani matsayi, matsa lamba na allura da zafin jiki ya kamata ya zama mafi girma.Adadin sanyinsa yana da hankali fiye da na PS, don haka ana buƙatar isassun matsa lamba, riƙe lokaci da lokacin sanyaya.Zagayowar gyare-gyaren zai zama ɗan tsayi fiye da na PS, kuma yawan zafin jiki na aiki shine 190-240 ° C.
HIPS resins suna shayar da danshi sannu a hankali, don haka bushewa gabaɗaya ba a buƙata.Wani lokaci danshi mai yawa a saman kayan za a iya tunawa, yana shafar ingancin bayyanar samfurin ƙarshe.Za a iya cire danshi mai yawa ta bushewa a 160 ° F na 2-3 hours.Akwai matsala na musamman na "fararen baki" a cikin sassan HIPS, wanda za'a iya inganta ta hanyar ƙara yawan zafin jiki da kuma matsa lamba, rage yawan riƙewa da lokaci, da dai sauransu, kuma tsarin ruwa a cikin samfurin zai zama mafi bayyane.
4.Typical aikace-aikace yankunan: Babban aikace-aikace yankunan ne marufi da disposables, kayan aiki, iyali kayan, kayan wasa da kuma nisha kayayyakin, da kuma gine-gine masana'antu.Matsayin mai ɗaukar wuta (UL V-0 da UL 5-V), an samar da polystyrene mai jure tasiri kuma an yi amfani dashi sosai a cikin kwandon TV, injin kasuwanci da samfuran lantarki.
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.
