Kukodzedwa polystyrene. Ndi chiyani icho?

Polystyrene thovu anaonekera mu m'ma makumi awiri. Iwo amapangidwa kuchokera granules polystyrene, analandira mu ndondomeko ya kuyenga. Choncho, polystyrene ndi m'munsi organic. Modabwitsa kwambiri ndi mankhwala uli ngakhale zakudya monga tchizi, sitiroberi, sinamoni, vinyo, ndi ena. Polystyrene chimatengedwa ngati sanali poizoni ndi ndale kuti zamoyo. Izi zikutanthauza kuti chinthu sangathe kuvulaza anthu ndipo angagwiritsidwe ntchito m'minda yosiyanasiyana ya zochita za anthu.

Foamed polystyrene zakonzedwa ndi kuchita thobvu ndi sintering ya mikanda ya polystyrene. Granules amawapopa pentane (zachilengedwezi mpweya condensate) ndi munthawi yomweyo kutentha nthunzi. Choncho, granule ndi chinawonjezeka ndi pafupifupi 50 nthawi, lisanduke mpira, wodzazidwa ndi mpweya. mpira Izi ndinapirira kwambiri ndi okhazikika, ndi ndondomeko n'zosiyana, i.e., "kuwomba", zimachokeradi. The Choncho analandira sintered polystyrene thovu mikanda ndi nthunzi. Likukhalira zinthu homogeneous. Thobvu ndi sintering njira kutenga malo imodzi.

Mwatsoka, Russian polystyrene kupanga kumachitika ntchito luso chakale. Iwo akutchedwa "njira ya kuyimitsidwa polymerization wa styrene pamaso pa jenereta nthunzi". Ngakhale makampani padziko lonse amagwiritsa mosalekeza polymerization njira mu misa. njira limachititsa kupeza mkulu khalidwe chuma pa mtengo wotsika.

Foamed polystyrene pafupifupi 100% mpweya. Iwo lilibe mankhwala zoonjezera. Nkhanizi ndi cholimba kwambiri, zilibe kusokonekera mchikakamizo cha chilengedwe. Choncho, ntchito mwakhama ntchito yomanga. Popeza polystyrene ali bwino matenthedwe madutsidwe, izo pafupifupi Kodi kachilombo chinyezi, si owopsa kwa anthu thanzi ndi chilengedwe.

Kumangidwa kwa polystyrene thovu ntchito ngati kutchinjiriza. Mwachitsanzo, polystyrene mbale 12 m'malo masentimita khoma lolimba makulidwe a 45 masentimita mtengo kapena njerwa kuti makulidwe a 2 m!

Technology kutchinjiriza makoma polystyrene mbale ndi lophweka. Iwo glued pamwamba ndi zomatira wapadera. Mphamvu zimfundo pakati pa slabs analimbitsa mapulagi pulasitiki ndi chipewa lonse. Pa kutchinjiriza Pamilunguyo mauna popewa pakutchulidwa wa ming'alu ndi deformations. kamangidwe aphimbidwa kachiwiri ndi njira ya ulimbo. Zotsatirazi kuwamaliza pulasitala kapena zipangizo zina zokongoletsera.

Buy polystyrene thovu ndi zophweka kwambiri. Iwo akhoza anasankha sitolo aliyense hardware. Ndi mtengo kuposa ena zipangizo kutchinjiriza. Pamene inu kugula n'kofunika kufotokoza ndendende zimene muyenera polystyrene. Iye ulipo magulu awiri - kwa kutchinjiriza makoma, ndi kutchinjiriza pansi. Woyamba si wandiweyani ngati wachiwiri. Isiyana polystyrene ndi pepala makulidwe - 20 mamilimita kwa 120 mm. Chisankho zimadalira ntchito akufuna. Childs, chifukwa kutchinjiriza makoma nyengo yathu pa muyezo khoma makulidwe mokwanira polystyrene 50 mm wandiweyani. Ngati kapangidwe ndi makoma zoonda, ndi polystyrene ayenera chachikulu. Ulamuliro N'chimodzimodzinso kusankha njira kwa alikuwotha moto pansi.
