Isticmaalka

3,3 ', 4,4-BipifyltetteracarBeracarxylic Dianhydride (BPDA)waa mid dhexe oo muhiim ah oo ku jira isku-darka dabiiciga ah waxayna leedahay codsiyo fara badan:

Poljeemide synthesis

• Aflaanta waxqabadka sare: Waxay mari kartaa falcelin polysisconsconsconsconsis ah oo leh xeryo dheeman ah si loo soo saaro filimada polyamimide. Filimaantaani waxay leeyihiin iska caabin heerkulka sare ah oo heer sare ah. Xitaa jawi heerkul sare ah oo ka sarreeya 200 ° C, wali way ilaalin karaan guryaha farsamada wanaagsan iyo dahaarka korantada. Sidaa daraadeed, waxaa badanaa loo isticmaalaa garoonka hawada ee ilaalinta mashiinka ee matoorka iyo qalabka korantada korantada ama aaladda saldhiga ah ee looxyada wareejinta ee dabacsan.
• Baaskiillada Injineerinka: Safarka Injineeriyada Polyide ee Polyamimes-ka Polyide waxay leeyihiin xoog sare, adkaan wanaagsan, sidoo kale waa iska cafiyaan. Waxay ku duri karaan si ay u soo saaraan qaar ka mid ah qaybo ka mid ah shuruudaha adag ee guryaha farsamada, sida galka yaryar ee ku xeeran matoorrada diyaaradaha iyo qaybo gudbin ah oo ka tirsan kormeeraha farsamada.
• Goobta dahaarka ah: Jeegaanterka polkimide-ka ayaa la isku dayaa iyada oo ku saleysan BPDA inay leeyihiin iska caabin aad u sahlan kiimiko. Markii lagu dabaqo derbiyada gudaha ee haamaha kaydinta kiimikada iyo kuwa wax ka qabashada, waxay ka hortagi karaan nabaad-guurka aashitada kaladuwan, saldhigyada, iyo dareeraha dabiiciga ah muddo dheer, hubinta in nolosha adeegga. Isla mar ahaantaana, waxay sidoo kale leeyihiin iska caabin kuleyl wanaagsan. Markii lagu daboolo tuubooyinka dareeraha-heerkulka iyo mashiinka, si sahlan ugama saari doonaan heerkulka sare awgeed.
• Alaabada Fiber: Waxaa loo isticmaalaa in lagu soo saaro fiilooyin aad u sarreeya. Fikradaha polyaride-ka ee la soo saaray waxay leeyihiin awood sare, modulus sare, iyo xasillooni heer sare ah. Waxaa badanaa loo isticmaalaa in lagu soo saaro dacwadaha dabka lagu sameeyo, xargaha gaarka ah ee loo yaqaan 'Aerospace', iwm.

Baakadaha iyo dhoofinta

20kg / Drum ama sida shuruudaha macaamiisha.
Waxaa iska leh alaabo caadi ah oo ay ku bixin karaan badda iyo hawada

Hayso oo keydin

Nolosha shelf: 24 bilood laga bilaabo taariikhda wax soo saarka ee baakadaha asalka u ah ee lagu keydiyo meel qabow oo qallalan oo ka baxsan iftiinka qorraxda tooska ah, biyaha.
Warehouse hawo qaboojiyey, qallajinta heerkulka hooseeya, oo laga soocay okers, acids.
