Ogwiritsa ntchito ambiri amaganiza zavutoli: thovu kapena polystyrene chithovu, kodi ndibwino kugwiritsa ntchito bwanji kukumbutsa komanso kumveketsa bwino? Ena amakhulupirira ngakhale kuti ndi zofanana mwamtheradi.
Izi zimatsimikizira zambiri pa intaneti. Mwachidziwikire, izi zimachitika chifukwa chakuti amapangidwa ndi polystyrene, koma ndikusangalala kuti mutha kuwona kuti kusiyana kumapezekabe.
Kusiyana kwa chithovu ndi polystyrene
Pokonza polystyrene pellets, nthunzi yowuma imayatsa thovu
Kusiyana kwakukulu pakati pa zinthuzi kuli motere:
- Mu ukadaulo wopanga makonda awa pali kusiyana kwakukulu. Polyfoam amapangidwa pogwiritsa ntchito pokonza polystyrene pellets ndi shopu youma. Kukula motsogozedwa ndi kutentha, amalimbana ndi wina ndi mnzake, pakadali pano ma Micropes amapangidwa. Polystyrene chithovu kapena penchlex – Ili ndiye dzina lake logulitsa, lopangidwa ndi njira yotatayendera. Ma granules a Polystyrene amasungunuka mu milandu yonseyi, zomangira zomangira zimapangidwa, kapangidwe kake kumachitika.
- Palinso kusiyana pakati pa mikhalidwe yakuthupi komanso yaukadaulo chifukwa cha ukadaulo wa kupanga kwawo. Ngati tiyankhula moona mtima, wokulitsa Polystyrene m'minda yosiyana ndi yapamwamba kuposa thovu.
Kusiyana kwazinthu zogwirira ntchito ndi mafuta
Kuchita bwino kwambiri kwa mafuta, woonda akhoza kukhala zinthuzo
Kodi ndibwino kugwiritsa ntchito chiyani pa kuperewera - chithovu cha polystyrene kapena chithovu?
Kusanthula kuthekera kwa zinthuzo zomwe zikuwunikidwa, kusiyana kwawo kungadziwike.
Khalidwe lalikulu la kutchinjiriza ndi mawonekedwe owoneka bwino.
Ndi kuchepa kwake, mphamvu ya zinthuzo zimachuluka, ndipo imakhala yocheperako.
- Digit ya mawonekedwe a polystyrene inali 0.028 w / mk;
- Polyfoam - 0.039 W / MK.
Poganizira izi, zitha kuonedwa kuti chithovu cha polystyrene chimaposa zomwe ziwiyazi, osati kokha, koma kuchuluka, zina, zina, zomwe zilipo.
Tsimikizani izi zitha kukhala mfundo zotsatirazi:

Ndi linga
Onjezerani polystyrene wocheperako kuposa pulasitiki wa thovu
Ndikofunikira kuti musaiwale kuti chithovu cha polystyrene ndi wonolith wabwino, ndipo tinthu tating'onoting'ono timakhomera. Izi zimakhudza kwambiri mphamvu ya zinthuzo.
Chithovu cha polystyrene sichitha kusweka kuchokera ku 0,4 mpaka 1 MPA, kukana kwake Kukakamizidwa ndi 0,25-0.5 MPA ndi 0.05-0.2 MPA.
Ndizodziwika bwino kuti chithovu, chowonekera pamachitidwe oyenda mwamphamvu, chimayamba kuphwanya mipira yaying'ono ndikusweka. Polystyrene imasungidwanso katundu wolimba komanso kusiyana kwa kutentha.
Kuchulukitsa kwa chithovu cha polystyrene kumasiyana kuchokera pa 30 mpaka 45 kg / m3, ndi thovu - madzi amasiyanasiyana pamtundu wa 15-35 kg.
Potha kuyamwa madzi
Polysifoam bwino amatenga madzi, omwe ndi chinthu choyipa
Ichi ndi chimodzi mwazinthu zofunika kwambiri zamagetsi, ndipo malowa azikhala ochepa. Mwakupeza chinyezi, kusungunuka kuleka mawonekedwe ofunikira kwambiri, adzatupa, kuti ayambe kuvunda ndi kugwa.
Mu polystyrene, omwe ali ndi ma cell, mayamwidwe am'madzi satero. Kumiza kwa nthawi yayitali komanso m'madzi kwathunthu, titha kudziwa kuti kuyamwa kwa madzi kumatha kukhala 0,2% ya voliyumu yake.
Polyfoam, yosiyanitsidwa ndi kapangidwe kake, izi ndizotsika kwambiri. Kumiza kwa maola 24 m'madzi, zitha kudziwika kuti zinthu zomwe zayamwa 2% ya voliyumu, m'masiku 30 zimatenga 4%.
Ndiye bwino kwambiri: thovu kapena chithovu cha polystyrene? Zonsezi pamwambapa zimatsimikiziranso zabwino za zinthu zachiwiri za Hydrophobic zakuthupi, makamaka ngati zimagwiritsidwa ntchito kugwiritsira ntchito madera ngati pansi, maziko ndi mawonekedwe.
Kwa Remictory
Kuchita zinthu moyenera kumachitika ngati chinthu chofunikira pomwe zinthu zikafunika kukhazikitsidwa ndi kukhalapo kwa nyumba zamatabwa - chipinda cham'miyala, padenga. Tiyenera kudziwa kuti zida zonsezi zimawerengedwa m'magulu a mphamvu yoyaka. Kuti mumve zambiri za kusiyana kwa zinthuzo, onani vidiyoyi:Nkhani pamutu: Woodrovnik mdziko mudzikolo
Wopanga adayamba kuwonjezera kupangidwa kwa chithovu ndikukulitsa polystyrene - ndi thandizo lake lokonzera. Ngati palibe kulumikizana mwachindunji ndi moto, zinthu zidzakokedwa m'masekondi.
Pa zokomera ku shrinkage
Mosiyana ndi pulasitiki ya thovu, polystyrene sizatha kuvuta
Choyipa chachikulu cha zotuwa zonse ndi shring. Ndi chodabwitsa chotere, pali mipata yomwe imachepetsa mphamvu ya njirayi.
Polyfoam akamatenthedwa ndi shrinkage, kotero musalimbikitsidwe kuyigwiritsa ntchito mu "dongosolo lotentha".
Ngati chithovu chimagwiritsidwa ntchito pakutulutsa kwa nkhope, ndikofunikira kuliphimba ndi pulasitala yoyera, yomwe imateteza ku magetsi a ultraviolet.
Chithovu cha polystyrene sichinapangitsidwe chifukwa cha shrinkage nthawi ya ntchito.
Pa kutentha kwa kutentha
Kutentha Kololedwa Kugwira ntchito ndi zinthu zonse - kuyambira 50 mpaka + madigiri.
Mukamapitilira zizindikiro izi, zinthuzo zimayamba kusokonekera.
Polyfoam nyali mpaka madigiri 310, yokulitsa polystyrene - pa madigiri 450.
Chiyambi
Kupanga zinthuzi si zinthu zovulaza, monga rewin ndi phenolal. Pambuyo pake, kusokonezeka sikuyamba kugawa zinthu zovulaza, atha kugwiritsidwa ntchito molimba mtima kupatukana nyumba ndi nyumba.Pa moyo wautumiki
Kafukufuku wawonetsa kuti pestlex, omwe amaikidwa molondola, amatha mpaka zaka 50, ndikusunga fomu.
Ngati kuthekera kwachuma kwa ogula musafikire izi musanagule, chithovu chitha kugwiritsidwa ntchito. Inde, inde, ndi otsika mtengo ndi thovu la polystyrene m'magulu, koma likhala chinthu chabwino kwambiri kuchokera kuphindu kotsika mtengo. Kuti mumve zambiri za katundu wa zikwama za polystyrene, onani vidiyoyi:
Ngati mungaganizire china chilichonse, ndiye yankho la funso: thovu kapena polystyrene chithovu, chomwe ndichabwino kuti chiuno:
