Waa maxay xaashida PP?

Guddiga PP, oo sidoo kale loo yaqaan POLYPropylene (PP) (PP PP SIYAASAD) (PP PP SITE, Golaha PP ee wax laga beddelay, guddiga PP-ga ee la xoojiyay, waa qalab-pp-ka pp-ka. Way adag tahay oo waxay leedahay dhibic dhalaalaya oo ka sarreeya PE. Maaddaama heerkulka nooca pp ee 'Hounopolymer' uu yahay mid aad u jajaban 0 ° C, alaabo badan oo ganacsi oo ganacsi ah ayaa ah 1-4% ethylene ama saamiga sare ee chefolutylen cluveyms.

Soo bandhig:

Magaca Waxsoosaarka: Nooca PP Copolymer wuxuu leeyahay heerkulka deg-degga kuleylka kuleylka hooseeya (100 ° C), daahfurnaan hooseeya, gloss hooseeya, adag, laakiin xoog leh saameyn xoog leh. Awoodda PP-ga ayaa kordhaya sida ay ka kooban tahay waxyaabaha kor ku xusan. Heerkulka jilicsanaanta vicat ee PP waa 150 ° C. Sababta oo ah heerka sare ee crystallillallinity, sheyni wuxuu leeyahay dusha sare ee dusha sare oo adag iyo xoqidda xoqidda. Ma jiro dhibaato ku saabsan jawiga ceyriska deegaanka ee PP. Caadi ahaan, PP-ga waxaa wax laga beddelay ku darista fiilooyinka galaaska, waxyaabaha lagu daro waxyaabaha lagu daro ama caag heerkul ah. Heerka qulqulka PP wuxuu leeyahay MFR oo u dhexeysa 1 ilaa 40. Qalabka MFP ee hooseeya ee MF PP waxay leeyihiin iska caabin saamayn leh oo saameynta leh laakiin ka hooseeya goynta hoose. Wixii agab isku mid ah MFR, xoogga nooca copolymymer-ka ayaa ka sarreeya kan nooca 'homopolmym nooca'. Sababo la xiriira crackstallition, heerka burburka ee PP aad ayuu u sarreeyaa, guud ahaan 1.8 illaa 2.5%. Iyo jihada isku-darka ah ee ka-goynta ayaa aad uga fiican agabyada sida PE-HD. Intaa waxaa dheer in 30% dhalada lagu daro waxay yareyn kartaa burburka 0.7%. Nooca 'Hounopolym' iyo labadaba nooca pp ee copolmymer-ka ah waxay leeyihiin cunno aad u wanaagsan oo caabbinta, aashitada iyo iska caabbinta aashitada iyo iska caabbinta aashitada, iyo iska caabbinta salka. Si kastaba ha noqotee, uma adkaysato hydrocarbons-ka udgoonnada sida benenentarbons, chlorind hydrocarbons (xajiyeyaasha kaarboon-cagaaran), iyo wixii la mid ah. PP ma laha iska caabbinta oks-ka heerkulka sare sida PE.

Kala-saaridda:

1. Gudiga PP: cufnaanta hoose, cufnaanta hoose, waa sahlan tahay well iyo geedi socodka, iska caabbinta kiimikada, iska caabin saafiga ah iyo iska caabin saafiga ah iyo iska caabin saafiga ah, oo aan sun lahayn, hadda mashruucii deegaanka u fiican.

2. PP: Waa xaashida qashinka laga soo qaaday

3.glass Fig xoojiyaha PP: GRAGE FORT LOO SOO DHAWEYSAA MADAXWEYNAHA MADAXWEYNE (FRPP): Ka dib markii lagu xoojiyaa furaha galaaska ah 20%, marka lagu daro sii wadida waxqabadka asalka ah, xoogga iyo adkaanta ayaa labanlaabmay marka la barbar dhigo PP, oo ay leedahay Iska ilaali feejignaanta wanaagsan iyo saamaynta heerkulka hooseeya. , iskahorimaadka anti-ka-hortagga iyo caabbinta arc, burburka hoose. Gaar ahaan ku habboon fiber-ka kiimikaarka, chlor-alkali, batroolka, cayayaanka, sunta cayayaanka, cuntada, dawada, warshadaha iftiinka, daaweynta bullaacadda, daaweynta kale.

4.Warka, beta (β)-β) -p) -pph xaashi aan la-koobi karin oo aan-ahayn. (β) Alaabada ayaa leh kuleylka kuleylka u adkaysiga kuleylka leh ee oksijiin u adkaysiga guryaha, nolosha muddada dheer iyo hantida farsamada wanaagsan. Waxaa si guul leh loogu adeegsaday soo saarista birta birta, iyo tikniyoolajiyadda horumarsan ay ku jirto booska ugu sareeya Shiinaha. Alaabooyinkan waxaa loo isticmaali karaa shaandhada taarikada iyo weelka nabarka ee wareega, keydka boogta ee Frrochemical, ee gaadiidka, dhirta tamarta, dhirta biyaha, bixinta biyaha, daaweynta biyaha, biyo-mareenka. iyo dhirta birta, korantada dhir ka saarida, maydhista iyo nidaamyada hawo-mareenka, iwm.

Codsi:

Xaashida la soo saaray ee PP waxay leedahay astaamaha miisaanka fudud, dhumucduhu, dusha sare, iska caabin wanaagsan, xoogga farsamada, kiimikada kiimikada, xasilloonida kiimikada, dahabka korantada iyo sunta. Gudiga PP-ka ayaa si balaadhan loogu isticmaalaa weelasha kiimikada, mashiinnada, qalabka elektronikada, qalabka korantada, baakadaha cuntada, daawada, dawada iyo daaweynta biyaha. Heerkulka wax ku oolka ah ee saxanka PP-ka ayaa gaari kara 100 digrii.
