Waxqabadka kale ee hordhaca ahgiraangiraha gacanta
Caag laastikada dabiiciga ah ee Vulcanized iyo cufnaantiisa iskuxiran maaha mid aad u sareysa, bartinimadu waa sarraysaa. Tusaale ahaan, in kala duwan ee 0-100 DEG C, elasticres at 50-85 DEG C, modules laastikada ee birta ah oo kaliya 1/3000, elongation tensile waa ilaa 1000%, ilaa 350%, ka dib markii dib u qallafsanaan joogto ah waa 15% oo kaliya, barti sare ee caag gacanta dabiiciga ah ka dib markii poly.
Xoogga caagga dabiiciga ah ee walxaha laastikada ah, caag dabiici ah oo cayriin ah, caag, caag vulcanized ah oo leh xoojinta sare. Xoogga jilicsan ee taayirrada gacan-gacan ee caagga ah ee vulkanized waxaa loo yaqaan xoogga cagaaran. Xoogga Cagaaran ee giraangiraha dabiiciga ah wuxuu gaari karaa 1.4 ilaa 2.5Mpa, xoogga Cagaaran ee saxda ah ayaa lagama maarmaan u ah socodsiinta taagerada gacan-gacan ee caagga ah. Awoodda jeexjeexa gacanta caagga ah ee dabiiciga ah ayaa sarreeya, ilaa 98kN/m, iyo caabbinta xirashada wanaagsan. Sababta xoogga badan ee farsamada gacanta ee caagga dabiiciga ah ayaa ah in uu iskiis u xoojinayo giraangiraha gacan-gacan ee caagga ah. Marka la kala bixiyo, silsiladaha makromolecular waxay u jeedaan jihada walaaca waxayna sameeyaan crystals.
caag dabiici ahgacan heedWaxqabadka korantada, taayir gacmeedka caagga dabiiciga ah waa mid aan-walax dabaylaha ahayn, waa shay dahaarka ka wanaagsan. Marka vulcanization caag dabiiciga ah ka dib markii hordhaca ah ee arrimo polarity, sida baaruud, dardar-, si wax qabadka dahaarka.
Guryaha gacan-ku-taagga ee caagga ah ee dabiiciga ah, giraangiraha gacan-gacan ee dabiiciga ah waa wax aan-walax dabaylaha ahayn, waxa ay ku milantaa kuwa aan -iyo kuwa aan -saliida polarka ahayn. Shaadhka gacan-gacmeedka caagga ah ee dabiiciga ah uma adkeysan karo cyclohexane, shidaalka, benzene iyo warbaahinta kale, caag aan vulcanized ahayn waxaa lagu milmi karaa dhexdhexaadka sare, barar gacan-gacan caag ah. Gacan-gacmeedka caagga ah ee dabiiciga ah, aan milmin ee acetone polar, ethanol, biyo badan oo aan milmi karin, adkaysi u leh 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide iyo wixii la mid ah.
Heerkulka kala-guurka dhalada ee caagga dabiiciga ah ee caag cayriin waa -72 Deg. C, heerkulka socodka balaastikada ah waa 130 sentigrade, bilawga heerkulku waa 200 digrii, heerkul aad u sareeya oo burburay waa 270 DEG C. Marka giraanta caagga dabiiciga ah ay vulcanized, Tg-giisa ayaa kor u kaca, mana dhaco qulqulo viscous ah.
Waxqabadka wheel Bakelite:
PF bakelite (bakelite, bakelite) alaabta dusha wheel iftiinka, qallafsanaanta farsamada ma fududa qallafsanaan, iska caabin khilaaf, iska caabin daxalka, caabbinta gabowga, fududahay in la nadiifiyo. Waxqabadka dahaarka bakelite-ga gacantu waa mid aad u xoogan oo aan saameyn ku yeelan kulaylka iyo qoyaanka, heerkulku wuu ka weyn yahay ama la mid yahay 140 darajo / Bakelite thermal deformation handwheel, iska caabin qabow oo xoog leh ayaa si caadi ah u shaqeyn kara deegaanka soddon darajo ka hooseeya eber.
