Polystyrene thovu. mafotokozedwe

Polystyrene thovu amapangidwa ndi luso lapadera. Kupanga ndondomeko lagawidwa magawo angapo. The mfundo yopanga polystyrene expandable lili.

Gawo loyamba ntchito mankhwala achilengedwe - pentane. mankhwala amakhala ndi luso mofulumira degradable mu nthaka, madzi ndi mpweya. Mothandizidwa pentane anagwira thobvu polystyrene. granules kenako pansi kutenthetsa. Kuti ntchito mpweya wotentha. Chifukwa ndi misa uniformly foamed. misa uyu ali ndi chabwino kapangidwe chatsekedwa-ma. Mu nkhaniyi pa mita kiyubiki ndende mpweya ndi wofanana ndi nainte-eyiti. Mpweya unazunguliridwa mu biliyoni ochepa maselo chatsekedwa. Polystyrene thovu ali makamaka dongosolo mkati zomwe imapereka otsika matenthedwe madutsidwe zakuthupi. Mlingo wa matenthedwe madutsidwe cha chuma ndi lofanana ndi index chomwecho mu akadali mpweya.

Polystyrene thovu chopangidwa ndi njira pamwamba pa yozizira solidifies ndi misa okhwima. kulemera Izi zikuphatikizapo maselo chatsekedwa wodzazidwa ndi mpweya. Khalidwe la zinthu zimadalira zipangizo ankagwiritsa ntchito pa kupanga. Mofanana kwambiri ndi zopangira imene chopangidwa polystyrene. Midadada thovu - ndi mankhwala amene yopanga nkhani funso umagwiritsidwa ntchito. Pa vuto la kuoneka chithovu angongole ndi mipira mzake.

Mabukuwa ntchito ngati insulant. Kukodzedwa polystyrene ali otsika matenthedwe madutsidwe, mlingo wa amene kumawonjezera ndi kuwonjezeka osalimba. Mabukuwa ali ndi kukana chinyezi. Polystyrene thovu si pathupi m'madzi ndipo alibe kupasuka mu izo. Kupezeka kwa kapangidwe sanali zimavuta selo muli mpweya pafupifupi mwathunthu kumathandiza malowedwe a chinyezi. Ngakhale ngati malowedwe a chinyezi pakati pa zinaphatikizidwa granules madzi mofulumira masamba zakuthupi osati wakulimbira pa izo ndi mavuto. Kukhala zinthu mkulu chinyezi ziribe mphamvu likuwonongekera zakuthupi - sizisintha iliyonse ya kukula kwake kapena mphamvu mawotchi kapena maonekedwe kapena chimateteza makhalidwe. Ngati mu ndondomeko kupanga zidzaphatikizapo optimizing akafuna akamaumba, limakupatsani kuonjezera mlingo wa pellets kusungunuka, madzi adzatha kuchepetsa kulanda.

The nthunzi gawo madzimadzi akhoza seep mu polystyrene lapansi. Nthunzi adzamasulidwa chuma ndi kulowa pa liwiro. Ngati iye amapita ku madzi mawonekedwe, zingakhale zovuta.

Mwa zina, nkhani kugonjetsedwa ndi zotsatira za mapangidwe mchere aukali. Kukodzedwa polystyrene n'zogwirizana ndi gypsum, simenti, dongo, phula, laimu ndi zina zipangizo ntchito yomanga ndi yokongola. Mabukuwa ndi kugonjetsedwa ndi zotsatira za mankhwala angapo mankhwala.
