nthuav polystyrene tshwm sim nyob rau hauv nruab nrab ntawm lub xyoo pua nees nkaum. Nws yog tsim los ntawm polystyrene granules tau nyob rau hauv cov txheej txheem ntawm cov roj refining. Yog li ntawd, polystyrene muaj cov hauv paus organic. Qhov tseem ceeb tshaj plaws yog tias cov tshuaj no muaj nyob hauv cov khoom noj xws li cheese, strawberries, cinnamon, wine thiab lwm yam. Polystyrene tau lees paub tias tsis muaj tshuaj lom thiab nruab nrab rau cov kab mob muaj sia. Qhov no txhais tau hais tias cov tshuaj no tsis muaj peev xwm ua mob rau tib neeg thiab tuaj yeem siv rau ntau qhov chaw ntawm tib neeg kev ua haujlwm.
nthuav polystyrene yog tau los ntawm foaming thiab sintering polystyrene granules. Cov granules yog pumped nrog pentane (qhov no yog natural gas condensate) nrog rau ib txhij cua sov nrog chav. Yog li ntawd, lub granule nce los ntawm yuav luag 50 lub sij hawm, tig mus rau hauv ib lub pob uas muaj huab cua. Lub pob no yog elastic heev thiab ruaj khov, thiab cov txheej txheem rov qab, uas yog, "deflation", tsis tshwm sim. Cov hlaws nthuav dav polystyrene yog li tau txais yog sintered nrog chav. Nws hloov tawm ib homogeneous khoom. Cov txheej txheem foaming thiab sintering tshwm sim ib txhij.
Hmoov tsis zoo, ntau lawm hauv Russiapolystyrene tshwm sim siv cov thev naus laus zis tsis tu ncua. Nws yog hu ua "txoj kev ncua kev kawm ntawv polymerization ntawm styrene nyob rau hauv lub xub ntiag ntawm ib tug vaporizer". Thaum lub ntiaj teb kev lag luam siv txoj kev nruam polymerization hauv huab hwm coj. Txoj kev no tso cai rau koj kom tau txais cov khoom zoo ntawm tus nqi qis.
nthuav polystyrene yog yuav luag 100% huab cua. Nws tsis muaj tshuaj ntxiv. Cov khoom siv no yog qhov ruaj khov heev, nws tsis tawg nyob rau hauv kev cuam tshuam ntawm ib puag ncig. Yog li ntawd, nws yog nquag siv nyob rau hauv kev tsim kho. Txij li thaum polystyrene muaj cov thermal conductivity zoo, nws xyaum tsis pub cov dej noo dhau mus, thiab tsis muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig.
Hauv kev tsim kho, nthuav dav polystyrene yog siv los ua lub tshuab cua sov. Piv txwv li, 12 cm tuab polystyrene board hloov lub phab ntsa ntoo 45 cm tuab los yog 2 meter tuab cib ntsa!
Cov cuab yeej ntawm phab ntsa rwb thaiv tsev nrog polystyrene boards yog qhov yooj yim heev. Lawv yog glued rau saum npoo nrog cov kua nplaum tshwj xeeb. Rau lub zog, cov pob qij txha ntawm daim hlau yog ntxiv nrog dowels nrog lub hau yas dav. Ib lub mesh yog glued mus rau lub rwb thaiv tsev kom tsis txhob tawg thiab deformations. Tus tsim yog them dua nrog cov kua nplaum. Qhov no yog ua raws li kev ua tiav nrog cov hniav plaster lossis lwm yam ntaub ntawv.
Kev yuav khoom nthuav dav polystyrene yooj yim heev. Koj tuaj yeem khaws nws ntawm txhua lub khw muag khoom kho vajtse. Nws yog pheej yig dua li lwm cov ntaub ntawv insulating. Thaum yuav khoom, koj yuav tsum txiav txim siab qhov twgpolystyrene yuav tsum tau. Nws yog ob hom - rau phab ntsa rwb thaiv tsev thiab hauv pem teb rwb thaiv tsev. Thawj tsis yog tuab li qhov thib ob. Polystyrene kuj txawv nyob rau hauv daim ntawv thickness - los ntawm 20 hli mus rau 120 hli. Qhov kev xaiv nyob ntawm qhov kev npaj ua haujlwm. Feem ntau, rau phab ntsa rwb thaiv tsev nyob rau hauv peb kev nyab xeeb, nrog ib tug qauv phab ntsa thickness, polystyrene 50 hli tuab yog txaus. Yog tias lub tsev muaj cov phab ntsa nyias, ces cov polystyrene yuav tsum thicker. Tib txoj cai siv rau xaiv qhov kev xaiv rau hauv pem teb rwb thaiv tsev.
