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 yoyamba.
(1).PS (polystyrene)
1. Kachitidwe ka PS:
PS ndi polima amorphous yokhala ndi madzi abwino komanso kuyamwa kwamadzi otsika (osakwana 00.2%).Ndi pulasitiki yowonekera yomwe ndi yosavuta kupanga ndi kukonza.Zogulitsa zake zimakhala ndi ma transmittance opepuka a 88-92%, kulimba kwamphamvu komanso kuuma kwakukulu.Komabe, zogulitsa za PS ndizosakhazikika, zomwe zimakonda kusweka kwamkati, zimakhala ndi kutentha kosakwanira (60-80 ° C), sizowopsa, ndipo zimakhala ndi mphamvu yokoka pafupifupi 1.04g\cm3 (yokulirapo pang'ono kuposa madzi).
Kuwomba shrinkage (mtengo wake nthawi zambiri ndi 0.004-0.007in/in), PS yowonekera - dzinali limangowonetsa kuwonekera kwa utomoni, osati crystallinity.(Chemical and physical properties: PSs zambiri zamalonda ndi transparent, amorphous materials. PS ali bwino kwambiri geometric bata, matenthedwe bata, kuwala kufala katundu, magetsi insulating properties, ndi kachitidwe kakang'ono kwambiri kuyamwa chinyezi. Imalimbana ndi madzi, diluted inorganic acids , koma akhoza kuipitsidwa ndi zidulo zamphamvu zotulutsa oxidizing monga concentrated sulfuric acid, ndipo zimatha kutupa ndi kupunduka mu zosungunulira za organic.)
2. Zochita za PS:
Malo osungunuka a PS ndi 166 ° C, kutentha kwa processing nthawi zambiri kumakhala 185-215 ° C, ndipo kutentha kosungunuka ndi 180 ~ 280 ° C.Pazinthu zoletsa moto, malire apamwamba ndi 250 ° C, ndipo kutentha kwa kuwonongeka kuli pafupifupi 290 ° C, kotero kuti kutentha kwake kumakhala kosiyanasiyana.
Kutentha kwa nkhungu ndi 40 ~ 50 ℃, kuthamanga kwa jekeseni: 200 ~ 600bar, kuthamanga kwa jekeseni kumalimbikitsidwa kuti mugwiritse ntchito mofulumira jekeseni, ndipo othamanga ndi zipata angagwiritse ntchito mitundu yonse ya zipata.Zipangizo za PS nthawi zambiri siziyenera kuuma musanazikonze pokhapokha zitasungidwa bwino.Ngati kuyanika kukufunika, kuyanika kovomerezeka ndi 80C kwa maola 2-3.
Chifukwa cha kutentha kwapadera kwa PS, nkhungu zina zimatha kusungunuka mwamsanga ndi kulimba zikapangidwa kuti ziwononge kutentha.Mlingo woziziritsa ndi wothamanga kuposa wamba wamba, ndipo nthawi yotsegulira nkhungu imatha kukhala kale.Nthawi ya pulasitiki ndi nthawi yozizira ndi yochepa, ndipo nthawi yozungulira yozungulira idzachepetsedwa;gloss wa mankhwala PS ndi bwino monga nkhungu kutentha ukuwonjezeka.
3.Zomwe zimagwiritsidwa ntchito: zonyamula katundu (zotengera, zisoti, mabotolo), zida zamankhwala zotayidwa, zoseweretsa, makapu, mipeni, zitsulo zamatepi, mawindo amphepo yamkuntho ndi zinthu zambiri za thovu - makatoni a dzira.Ma tray onyamula nyama ndi nkhuku, zolemba zamabotolo ndi zida zopangira thovu za PS, zonyamula katundu, zinthu zapakhomo (zodula, thireyi, ndi zina), zamagetsi (zotengera zowonekera, zoyatsira magetsi, makanema otsekereza, ndi zina).
(2).HIPS (modified polystyrene)
1. Kachitidwe ka HIPS:
HIPS ndi zinthu zosinthidwa za PS.Lili ndi gawo la mphira la 5-15% mu molekyulu.Kulimba kwake kumakhala kokwera kanayi kuposa kwa PS, ndipo mphamvu yake imakula kwambiri (polystyrene yapamwamba).Ili ndi giredi yoletsa moto komanso kupsinjika kwa crack.magiredi, magiredi onyezimira kwambiri, magiredi olimba kwambiri, magiredi olimbitsa magalasi, komanso magiredi otsalira osinthika.
Zina zofunika za HIPS yokhazikika: mphamvu yopindika 13.8-55.1MPa;mphamvu zolimba 13.8-41.4MPa;elongation pa yopuma 15-75%;kachulukidwe 1.035-1.04 g/ml;Ubwino wake.Zolemba za HIPS ndizowoneka bwino.HIPS imakhala ndi madzi otsika ndipo imatha kukonzedwa popanda kuyanika.
2. Zochita za HIPS:
Chifukwa mamolekyu a HIPS ali ndi mphira wa 5-15%, womwe umakhudza madzi ake pamlingo winawake, kuthamanga kwa jekeseni ndi kutentha kwapangidwe kuyenera kukhala kokwera.Kuzizira kwake kumakhala pang'onopang'ono kuposa kwa PS, kotero kuti kukakamiza kokwanira, kusunga nthawi ndi nthawi yozizira kumafunika.Kuzungulira kozungulira kudzakhala kotalikirapo pang'ono kuposa kwa PS, ndipo kutentha kwanyengo kumakhala 190-240 ° C.
Utoto wa HIPS umatenga chinyezi pang'onopang'ono, kotero kuyanika sikofunika.Nthawi zina chinyezi chochuluka pamwamba pa zinthuzo chimatha kuyamwa, zomwe zimakhudza maonekedwe a chinthu chomaliza.Madzi ochulukirapo amatha kuchotsedwa poyanika pa 160 ° F kwa maola 2-3.Pali vuto lapadera la "m'mphepete mwa nthiti" m'zigawo za HIPS, zomwe zingathe kukonzedwa bwino mwa kuwonjezera kutentha kwa nkhungu ndi mphamvu ya clamping, kuchepetsa kukakamiza kugwira ntchito ndi nthawi, ndi zina zotero, ndipo mawonekedwe a madzi mu mankhwalawa adzakhala omveka bwino.
4.Magawo ogwiritsira ntchito: Malo ogwiritsira ntchito kwambiri ndi zoyikapo ndi zotayika, zida, zida zapakhomo, zoseweretsa ndi zosangalatsa, ndi mafakitale omanga.Flame retardant grade (UL V-0 ndi UL 5-V), polystyrene yolimbana ndi mphamvu yapangidwa ndikugwiritsidwa ntchito kwambiri m'makaseti a TV, makina abizinesi ndi zinthu zamagetsi.
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.
