Polycarbonate - izo kwa chuma ntchito ndi kumene?

zipangizo Polymeric tsopano anapeza ambiri ntchito yomanga nyumba ndi nyumba zolinga zosiyana. Mwa Iwo polycarbonate - ndi gulu kuti tichipeza zigawo ziwiri kapena zitatu, pakati limene nthiti longitudinally zochokera. Chifukwa kukonza ma imeneyi kwathandiza kwambiri kuti tikwaniritse mawotchi mphamvu pa tsamba otsika kulemera.

Kufotokozera polycarbonate

Polycarbonate mu gawo mtanda akufanana khungu, kumene kungakhale triangular kapena anayi. Monga zopangira ntchito polycarbonate izi granulated sipangakhalenso akamagwira condensation mankhwala dihydroxy ndi polyesters carbonic acid. Chuma malinga ndi Lachiwiri-2256-001-54141872-2006, koma kukula zolamulidzwazo potsata malamulo amenewa akhoza kusintha malingana ndi zofuna za makasitomala. Magawo stiffeners ofunitsitsa ndi Mlengi, ndi kupatuka pazipita si anaika.

Kutentha modes wa ntchito

Polycarbonate ali kukana mkulu zinthu chokhwima zachilengedwe. zinthu Kutentha ntchito amadalira kalasi ya umisiri zinthu zoletsedwa ndi yaiwisi khalidwe zakuthupi. Kwa mitundu kwambiri mapanelo chithunzi ichi ranges ku madigiri -40 kuti +130. Mitundu ina ya nkhaniyo anafotokoza chingathe kupirira otsika kutentha kwambiri kuti ndi ofanana digiri -100. Kapangidwe si anawonongedwa. Atadziŵa kutenthetsa kapena kuzirala mwina kusintha mu miyeso liniya. kuwonjezeka chovomerezeka sayenera oposa 3 millimeters 1 mita, ndi nkhani ya m'lifupi ndipo kutalika kwa pepalalo. Chifukwa kuti polycarbonate chuma ali ndi lalikulu ikukhudzana ndi thambo ayenera kuikidwa ndi clearances yoyenera.

Chemical kukaniza

Izo ziyenera kuganizira mfundo yakuti amachitiridwa mitundu yonse ya zinthu zowononga ntchito mapanelo kukongoletsa. Polycarbonate - izi ndi zinthu zimene ali kukana kwambiri kuti chiwerengero cha mankhwala. Komabe ali osavomerezeka ntchito ukonde, ngati iwo angakhoze bwanji aerosols insecticidal, simenti kusakaniza plasticized PVC chuma, konkire, detergents amphamvu, halogen ndi solvents onunkhira, zomatira zochokera amoniya, asidi acetic ndi njira soda wa ethyl mowa.

polycarbonate kukana kuti mankhwala

Polycarbonate - izi ndi zinthu zimene zidzakhala mpaka zotsatira za njira saline ndi ndale anachita asidi ndi anaikira mchere zidulo. The mapanelo samuopa reductants ndi oxidants, komanso njira mowa, amachita ngati zosiyana methanol. Pamene khazikitsa masamba ayenera kugwiritsa ntchito mankhwala ena omatira silikoni ndi kusindikiza zinthu mwapadera linapereka iwo.

mphamvu mawotchi

Polycarbonate akhoza kukumana mawotchi katundu kwambiri. Iwo ayenera kumvetsa kuti pamwamba akhoza pansi kumva kuwawa pa kukhudzana yaitali ndi zinthu ka mtundu wa mchenga. Choncho, mapangidwe zimakhalapo atadziŵa zipangizo akhakula, amene kuuma chokwanira. Mawotchi mphamvu kudzadalira kapangidwe ndi mtundu. Ngati ife kulankhula za kulimba kwamakokedwe, mankhwala umafunika ali ndi chizindikiro wofanana 60 MPa. Maganizo zokolola pa chizindikiro chomwecho ndi 70 MPa. Impact mphamvu ndi 65 KJ / mm. Mlengi amapereka chitsimikizo kusunga ntchito a zaka zoposa 10 pokhapokha mapepala akhala anaika molondola ndi ntchito fasteners wapadera.

Magawo makulidwe ndi kulemera yeniyeni

Njira imene ikukhudza kuthekera zotsimikizira polycarbonate zamitundu yosiyanasiyana. Panopa msika zipangizo yomanga angapezeke mapepala amene makulidwe zimasiyanasiyana millimeters 4 mpaka 25. Aliyense wa mitundu yosiyanasiyana ya kapangidwe mkati. polycarbonate kachulukidwe ndi makilogalamu 1.2 pa mita kiyubiki. Pakuti webs chigawo yogwira zimadalira chiwerengero cha zigawo, ndi makulidwe a mapanelo ndi mtunda pakati stiffeners lapansi. Pamene pepala makulidwe a 4 millimeter nambala okha ndi makoma awiri, mmene mtunda pakati pa nthiti ndi 6 millimeters. Ndi makulidwe 25 millimeters ndi wofanana ndi chiwerengero cha makoma 5, pamene phula pakati pa nthiti ndi 20.

Kukana kwa dzuwa

Polycarbonate - izi ndi zinthu zimene akhoza kuonetsetsa chitetezo chodalirika ku cheza. Pofuna kukwaniritsa mawu amenewa, mu ndondomeko yopanga kwa ofunika chinsalu cha interlayer ❖ kuyanika umagwiritsidwa ntchito. Njira imeneyi amapereka ntchito kwa zaka 10. Mwina delamination wa ❖ kuyanika kuteteza chuma pakokha, monga polima ndi zinaphatikizidwa adzatsekeredwa maziko a. Unsembe wa pepala ayenera kuganizira nthawi kuti ❖ kuyanika anafuna chitetezo cheza dzuwa kuti kukopedwa. Kuwala kufala zimadalira mtundu Mwachitsanzo, mapepala sanali wachikuda ali akalozera izi kuyambira 83 mpaka 90 peresenti. Transparent wachikuda nsalu musaphonye maperesenti oposa 65 Komabe, kuwala opatsirana ndi anamwazikana bwino.

Matenthedwe makhalidwe kutchinjiriza

Pomanga greenhouses anapanga polycarbonate, amene ndi zinthu izi, muyenera kudziwa pasadakhale. Iwo ali kwambiri katundu matenthedwe kutchinjiriza. Teplosoprotivlyaemost nkhaniyi zimatheka ndi internally munali mpweya ndi chifukwa chakuti pa intaneti ali ndithu matenthedwe kukana. Kutentha kutengerapo koyefishienti kudzadalira kapangidwe ndi pepala makulidwe. chizindikiro ichi zimasiyanasiyana 4.1 kuti 1.4 W / (m² · K). The manambala woyamba ndi oyenera intaneti, kakakulu umene uli wofanana 4 millimeters, pamene nambala wachiwiri ukufanizidwa ndi pepala 32 mm. Polycarbonate - ndi pulasitiki, ntchito imene nkokoma ngati pamene kuli kofunikira kuphatikiza kwambiri makhalidwe matenthedwe kutchinjiriza ndi mkulu chilungamo.

moto

Polycarbonate akuti ndi kugonjetsedwa ndi kutentha, adzaupereka kwa B1 gulu, wa gulu la European anam'patsa flammability ndi zinthu kudziletsa wozimitsa. Pamene kutenthedwa, zilibe zimatulutsa mpweya woipa komanso si owopsa kwa anthu. Mu anafotokoza kanthu matenthedwe lokhudza ndi lawi lotseguka, njira ya kuyambira kudzera maenje ndi wovulala kukonza. Zofunika umayamba kuchepa mu kukula.

moyo

Monolithic polycarbonate - izi ndi zinthu zomwe opanga zimatsimikizira kuteteza makhalidwe Mkhalidwe wa mfundo zaka 10. Izi ndi zoona malamulo ndi Pamilunguyo unsembe ntchito. Ngati apewe kusokoneza pamwamba akunja, n'zotheka zokulitsa ntchito ya gulu la. Apo ayi, kulephera msanga wa tsamba. M'madera amene pali chiopsezo cha kuwonongeka makina, m'pofunika kugwiritsa ntchito mapepala ndi makulidwe wofanana kapena kuposa 16 millimeters. Pamene ogwiritsa n'kofunika kuganizira kuchotsa kuthekera kukhudzana ndi zinthu zimene zingasokoneze mu mawonekedwe a chiwonongeko.

phokoso makhalidwe kutchinjiriza

Kapangidwe zisa imapereka otsika kwambiri lamayimbidwe permeability, amasonyeza kuti mapanelo ndi phokoso kwambiri kungolandira katundu kuti zimasiyana ndi mtundu wa pepala ndi matabwa ake mkati. Choncho, nkhani ya polycarbonate multilayer selo makulidwe a intaneti amene 16 millimeters kapena zambiri, phokoso mafunde kutha kumachitika mu osiyanasiyana 10 21 DB.

Pomaliza

Tikhoza kunena kuti Plexiglas - polycarbonate ndi zochepa kwambiri khalidwe makhalidwe. Mtundu yachiwiri zakuthupi ali mphamvu apamwamba ndiponso kudalirika amenewa ndi ambiri makhalidwe ena khalidwe dongosolo uchi amusankha kawirikawiri. Ichi ndi chifukwa chakuti polycarbonate ntchito zosiyanasiyana m'madera kuphatikizapo ntchito yomanga ndi kukonza. ogula Private akusankha izo kwa chilengedwe cha madenga, greenhouses, pergolas ndi zambiri. Kulengedwa kwa iwo amene analandira mosavuta popanda kumanga maziko wapadera. Izi kumachepetsa ndalama ndi zimatithandiza ndondomeko ntchito.
