Polystyrene chithovu chofunda: Mitundu ndi dongosolo la kutchinga

Njira yopangira chitsutso masiku ano ndikumvetsera mwachidwi, chifukwa zimatengera mphamvu, momwe zimakhalira ndi mphamvu zokhala ndi malo okhala kapena malo okhala.

Zowonadi, tsopano perekani chidwi kwambiri kuteteza kutentha m'chipindacho, chifukwa cha zotenthetsera (nkhuni, malasha kapena magetsi) ndizomwe zimapangidwa kuti zizigwira ntchito ndi zinthu zotenthetsera. Nthawi zambiri amagwiritsa ntchito polystyrene ndi ubweya wamchere, kuphatikizapo zotupa za polystyrene zokhala pansi.

Polystyrene chithovu cha pansi pazinthu ndi mitundu

Pansi yotentha ndi mtundu wamakono wotentha, womwe eni ake ambiri amalota ndipo akufuna kuyambitsa malo okhala. Dongosolo lotentha ili likhala lofunikira komanso lowonjezera pakutenthetsera.

Kutalika kwa "keke" yamadzi kuyenera kukhala 7-9 masentimita, ndi magetsi 6-8 masentimita.

Zipinda zofunda sizikhala kulikonse, chifukwa zili pansi pa chivundikiro, koma pali zovuta zambiri pakukhazikitsa, chifukwa ndizofunikira kuthira mangani owonjezera, amachepetsa kutalika kwa chipindacho ndipo amagwiranso katundu wowonjezera.

Anthu samatengedwa nthawi zonse kukonza matenthedwe omwe ali ndi zophophonya za zolakwazo, koma m'zaka zaposachedwa, omanga ambiri athetsedwa vuto ili, chifukwa chazotuluka zapadera - polystyrene polystyrene pamsika.

Izi zili ndi kulemera kochepa, makulidwe ochepa (2-5 masentimita), komanso kosavuta komanso yokhazikika.

Zojambula za Polystyrene chithovu

Zinthu zopikisana mpaka kutentha mpaka + 80 madigiri

Chithovu cha polystyrene ndichabwino kuti chilengedwe choyambirira cha "keke" pansi, chifukwa chimakhala ndi mawonekedwe osalala omwe amaphatikizidwa mwangwiro ndi omwe anyamuka. Ili ndi mawonekedwe owoneka bwino. Monga zomangamanga zina zilizonse, wokulitsa polystyrene ali ndi mawonekedwe ake:

1. Itha kugwiritsidwa ntchito ndikuyikidwa ndi zisonyezo zilizonse za kutentha: kuchokera -65 mpaka + 80 ° C.
2. Kapangidwe kakang'ono ka zinthuzo kumatha kupereka chuma chabwino kwambiri chogwiritsira ntchito, chokhala ndi mawonekedwe a 0.036 - 0.044 w / m2.
3. Zotsatira za kapangidwe kodzaza mpweya ndi kulemera kochepa kwa mbale.
4. Zinthu zomwe zimatha kugwira ntchito 2 - kuthilira kumadzi, chifukwa sikutenga chinyezi.
5. Zinthu za polystyrene zili ndi chitetezo chabwino. GAWE LISED 2 CM imatha kuchepetsa phokoso la 20 DB.
6. Polystyrene ali ndi zodzikongoletsera mphamvu ndipo ali ndi mawonekedwe otsika, koma pakusintha zinthu zomwe zingawononge zinthu zingapo zovulaza thanzi la anthu.

Tiyenera kudziwika kuti chithovu cha polystyrene ndi wachibale mwachindunji cha chithovu, koma ali ndi kachulukidwe kakang'ono katatu ndi kapangidwe kakang'ono kwambiri, komwe kumawonetsa mtengo waukulu.

Tiyenera kukumbukira kuti matenthedwe a 10 cm a polystyrene kumenyetsa kumafanana ndi 1 m wa njerwa zomangazi ndi 37.5 masentimita nkhuni.

Nkhani pamutu: Zingwe zopitilira pa Hook: magawo akuluakulu a ntchito

Zosiyanasiyana zokulitsa polystyrene

Zovala Zosavuta ndi Kuswa

Opanga ambiri a polystyrene amagwiritsa ntchito matekinoloje osiyanasiyana a materikino, omwe amatsogolera ku chilengedwe cha mitundu yosiyanasiyana. Mpaka pano, pali mitundu yotsatirayi:

1. Matalala osagwirizana ndi polystyrene (EPS, psb-c). Njira youma granules imapangidwa kawiri. Kamodzi asanamenyedwe, komanso kawiri patatha chochitika ichi. Kenako zinthu zopangira ndi mabotolo. Ichi ndiye mtundu wofala kwambiri wa kupanga kwa polystyrene chithovu, chili ndi ndalama zazing'ono kwambiri, koma ndi zinthu zosalimba kwambiri.
2. Kutalika (eps, xps). Kupanga uku kumadziwika chifukwa chopanga kupanga kudutsa pansi pa chidebe winawake, pomwe kumayambiriro kwapadera kumayambitsidwa. Pambuyo pake, unyinji wonse udafinya kudzera mu extruder kale ngati mawonekedwe a mbale ndikuwuma.
3. Kukanikiza polystyrene (Psal-1, PS-4) ali ndi mawonekedwe omwewo, komanso njira zotalika, koma zopangidwa, koma zopanga ndizosiyana.
4. Njira yopanga Autoclave siyosiyana ndi kutukusira, kokha polumala magena, opanga amagwiritsa ntchito Autoclave. Zinthu zotere sizimagwiritsidwa ntchito ngati mafuta.

Tiyenera kudziwika kuti pazinthu zopanga mu polystyrene kumenyetsa kwa polystyrene, zowonjezera zapadera zimawonjezeredwa, zomwe zimakhala ndi zinthu zoyipa, zomwe zimawonjezera zinthu zomanga moto. Kugwiritsa ntchito zowonjezera izi kumayendetsedwa ndi kost - 15588-86.

Kodi mungasankhe bwanji kudziyesa nokha?

Aliyense amene watenga nawo akufuna kuwonetsetsa kuti zinthu zabwino kwambiri zimagwiritsidwa ntchito pamalo omanga, zimagwiranso chithovu cha polystyrene. Kusankha zinthu pansi pa pansi, muyenera kusamala ndi:

1. Mtundu wazogulitsa. Ziyenera kukhala zowala pamwamba chonse.
2. Fungo liyenera kulibe. Fungo lakuthwa kuchokera ku zinthuzo limafanana ndi mawonekedwe otsika komanso osalondola.
3. Mphepete mwa malonda ayenera kukhala ndi kachulukidwe kathunthu.
4. Malo osalala popanda ma bakeni kapena mababu.
5. Ma granules ofanana.

Kusankha nkhaniyo, mutha kudzipereka pawokha kudziyesa kochepa: muyenera kuthyola mbale imodzi ndi kusanthula malo agawanika.

Ngati chotchino chidasweka pamalo olakwika, ndipo mafunde (ma granules adangokhala manambala), zikutanthauza kuti kuwombera sikunali kolakwika, ndipo izi siziyenera kugulidwa. Zokhudza kusankha chotenthetsera pansi lotentha, onani vidiyoyi:

Nkhani pamutu: Zoyenera kuchita ngati kusamba kukuyenda

Mawonekedwe a kukhazikitsa kwa polystyrene chiuno pansi chotentha

Malonda okumba ayenera kukhala ovala bwino

Pansi yotentha siyofunikira kulinganiza konkriti wakuda. Kapangidwe kake katha kukhala pansi pamatabwa, chinthu chachikulu ndikuti mbale za polystyrene chithovu chakhazikika kwa wina ndi mnzake.

Musanasungire slab slab, ndikofunikira kuyeretsa zokutira ku zinyalala ndikuchotsa zosagwirizana ndi zosafunikira.

Zitha kutenga kukonza zokutira zokhala ndi zosakaniza zapadera, zokhala ndi ming'alu yonse ndikuwonongeka.

Mukakhala otsimikiza kuti pamwambayo ndi yosalala komanso yoyera, mutha kuyambitsa kuyika kwa mbale zowomba za polystyrene. Nthawi yomweyo, gawo lililonse la malonda siliyenera kulembedwa ndikuyenda. Kufikira pamanja zonse zokutira kuyenera kukhala zolimba kumakoma.

Akatswiri ambiri amalimbikitsa kugwiritsa ntchito filimu ya thermacaccution poyiyika pansi pa kusokonezeka ndipo potero kumathandizira chitetezo chaphokoso komanso kutentha kwa mafuta.

Opanga angapo a polystyrene amapanga mbale ndi zotayidwa ndi spikes. Mukakhazikitsa chisudzo chotere, muyenera kulabadira mfundo yoti zinthu zokopa sizinawonongeke.

Zilonda zapadera za kugonana mosagwirizana sizimangolumikiza maroovu, komanso oyikitsira matope ogona kapena chingwe.

Nthawi zambiri, awiriawiri amasuiters ali pamtunda wa masentimita 3-8 kuchokera kwa wina ndi mnzake, potero akuloleza kuti musankhe mtunda pakati pa zinthu zotenthetsera.

Pambuyo pogona chingwe kapena mapaipi pakati pa oyenda, kukhazikitsidwa koyesedwa kuyenera kupangidwa ndikuphimba zinthu zotenthetsera ndi filimu yothira madzi (ndi pansi madzi otentha).

Kuvala kosavuta, monga materite kapena laminate, kumatha kudulidwa pamwamba pa thovu la polystyrene, ndipo zida zogulira (Linoleum, kapeti) ndi slabe, yomwe ili chitsulo, yomwe ili chitsulo.

M'zipinda zokhala ndi chinyezi chambiri, zosakaniza zokhazokha zimagwiritsidwa ntchito, zomwe zimathiridwa pa kusokonezeka, mu gawo limodzi lokhala ndi ziwalo zogona.

Nkhani pamutu: 43 Khonsolo yoyambirira! Zingwe zazing'ono zomwe aliyense ayenera kudziwa (chithunzi, kusankha)

Chitsanzo chimodzi cha pansi chimatha kuwoneka kuchokera ku chithunzi.

Kuchokera munkhaniyi, aliyense akakugogomezera za chidziwitso chosankha chithovu cha polysthyrene cha pansi. Ndikofunika kusankha ndi njira yake, popereka zophophonya zonse ndi zabwino. Kusankha zinthu kuyenera kuchitidwa nokha nokha.
