PB Hot ndi chitoliro chamadzi
Kuyamba kwa PB Hot ndi Ozizira Madzi
Polybuuten (PB) chitoliro ndi chokwera kwambiri chokwera. PB Ortin ndi polymer zosokoneza bongo kuchokera ku Butene- 1. Imakhala ndi kachulukidwe kaziya wa 0,937 g / cm3 crystal, yomwe ndi thupi lonyansa lomwe limasinthira. Ndi wa zinthu zapamwamba zamagetsi zamankhwala olemera. Ndipo ali ndi kutentha kwambiri, kulimba, kukhazikika kwamankhwala ndi pulasitiki.
Ndiwopanda pake, wopanda mphamvu, wonunkhira, amakhala ndi kutentha kwa -3 ° C '100
Zaka). Ndipo ili ndi machitidwe omwe amakalamba nthawi yayitali. Ndi imodzi mwazinthu zodulidwa kwambiri zamagetsi padziko lapansi. Amagwiritsidwa ntchito kwambiri m'maiko ambiri padziko lapansi. Ndipo ili ndi mbiri ya "Golide mkati
pulasitiki ".
PB Hot ndi kuzizira kwamadzi
Zosasinthika Zakale Zopangidwa mu semiconductocy zokonzedwa ndizoyengedwa ndikubwezerezedwanso ndi chipangizo chogwirira ntchito kuti mupange mafuta a 40-1, ndikuvula madzi a C01. Izi zimagwiritsidwa ntchito makamaka popanga mapanelo amadzimadzi, semiconductor yophatikizira mabwalo ndi njira zina.
Mawonekedwe otentha ndi ozizira mapaipi
1.Tikulemera, wosinthika komanso wosavuta kumanga. Kulemera kwa PB chitoliro ndi pafupifupi 1/5 ya chitoliro chachitsulo. Zimasinthasintha komanso zosavuta kunyamula. Ma radius ocheperako ndi 6D (D: Wepe Dipeter). Imatengera kulumikizana kotentha kapena kulumikizana kwamakina, komwe kumakhala kovuta pomanga.
2. Ili ndi kukhazikika kwabwino, osati poizoni komanso popanda vuto. Chifukwa cha kulemera kwake kwamtundu wake, kapangidwe kake kazithunzi kamakhazikika. Ndiwopanda kupweteka komanso osavulaza ndipo ali ndi moyo wotumikira zaka zosakwana 50 popanda radiation ya ultraviolet.
3.T ali ndi chisanu kukana ndi kukana kutentha. Ngakhale -2 ° C, imatha kukhalabe ndi kutentha kwambiri. Pambuyo pa kusuta, chitolirocho chimabwereranso ku mawonekedwe ake oyamba. Pansi pa 100 ℃, magawo onse a magwiridwe antchito amasungidwa bwino.
4.Imakhala ndi makhoma osalala ndipo samakhala ndi sikelo. Poyerekeza ndi mapaipi ankhondo, imatha kuwonjezera madzi ndi 30%.
5.Imasavuta kukonza. Pamene PB yopeyodwa, si yolumikizidwa konkriti. Ikawonongeka, imatha kukonzedwa mwachangu posintha chitoliro. Komabe, ndibwino kugwiritsa ntchito kasomba (chitoliro mu chitoliro) njira yogulira mapaipi apulasitiki. Choyamba, kuphimba chitoliro cha PB ndi chitoliro cha PVC sitemberedwe, kenako ndikuyika, ndikukonzanso mtsogolo
ikhoza kutsimikizika.
