Waa maxay xabagta batroolku? Waa maxay qaybaha ugu muhiimsan?

2022-10-26

Xabagta batroolku waa nooc ka mid ah xabagta epoxy-ga oo miisaankeedu yar yahay. Miisaanka kelli guud ahaan wuu ka hooseeyaa 2000. Waxay leedahay ductility kulaylka waxayna milmi kartaa dareerayaasha, gaar ahaan dareerayaasha dabiiciga ah ee saliidda cayriin. Waxay si fiican ula jaanqaadi kartaa walxaha kale ee xabagta. Waxay leedahay caabbinta abrasion tayo sare leh iyo iska caabin gabowga. Halbeegyada waxqabadkeeda muhiimka ah waxaa ka mid ah barta jilicsan, hue, unsaturation, qiimaha acid, qiimaha saponification, cufnaanta qaraabada, iyo wixii la mid ah.

Barta jilicsani waa sifada muhiimka ah ee xabagta batroolka, taas oo macnaheedu yahay in xooggiisa, jajabnaantiisa, iyo viscosity ay ku kala duwan yihiin codsiga, barta jilicsan ee loo baahan yahayna way ka duwan tahay. Xaaladaha caadiga ah, barta jilicsan ee wax soo saarka warshadaha ee caag vulcanized ah waa 70 ° C ilaa 1000 ° C, barta jilicsan ee wax soo saarka warshadaha ee dahaarka iyo rinjiga waa 100 ° C ilaa 1200 ° C.

Intaa waxaa dheer, heerka isbeddelka tonal ee uu keeno iftiinka ultraviolet iyo saamaynta kulaylka ayaa sidoo kale ah cabbir waxqabad oo aad muhiim u ah. Qiimaha aysiidhka looma isticmaali karo oo keliya in lagu ogaado awoodda kaydinta birta-saldhigga aashitada laakiin sidoo kale in lagu ogaado qaybaha karbonyl iyo karboksyl ee kaydinta resin batroolka sababtuna tahay oksaydhkeeda.

Halabuurka xabagta batroolka ayaa ah mid aad u adag. Suuqgeynta iyo kor u qaadista adeegsigeeda ugu weyn, waxaa jira noocyo badan oo badan, kuwaas oo qiyaas ahaan loo qaybin karo shan qaybood:

â  Dufanka jidhka bini'aadamka, resin cycloaliphatic epoxy, oo guud ahaan laga diyaariyey jajab C5, oo sidoo kale loo yaqaan C5 epoxy resin;

â¡ p-xylene epoxy resin, guud ahaan laga sameeyay jajabka C9, sidoo kale loo yaqaan C9 epoxy resin;

â ¢ p-xylene-aliphatic hydrocarbon copolymer resin epoxy, oo sidoo kale loo yaqaan C5/C9 resin epoxy;

â£Dicyclopentadiene epoxy resin, oo laga sameeyay dicyclopentadiene ama xeryahooda, waxaa sidoo kale loo yaqaannaa DCPD epoxy resin. Sababtoo ah xabagta epoxy-ga ayaa leh kooxo hydrocarbon aliphatic ah oo aan buuxin, waxaa sidoo kale loo yaqaannaa resinka oksijiinta

⤠Xabagta batroolka ee hydrocracking, guud ahaan C5 ama C9 resin epoxy waa casaan bunni ah ilaa huruud khafiif ah wuxuuna noqon karaa caano cad ama translucent ka dib biyo-qarxinta.

Xabagta batroolka waxaa inta badan loo isticmaalaa daaha-dhismaha, xabagta, daabacaadda qalinka, waxyaalaha lagu ilaaliyo, iyo agabka caagga la beddelay. Iyada oo horumarka joogtada ah ee tignoolajiyada resin-ka, isticmaalkeeda ugu weyn ayaa sidoo kale si joogto ah u koraya. C5 epoxy resin waa qayb leh horumar degdeg ah heerkan, waxaana si weyn loogu isticmaalaa daaha-dhismaha, khadadka daabacaadda, shaabadeynta, isku xidhka iyo warshadaha kale. C9 epoxy resin waxaa si weyn loogu isticmaalaa rinjiga, caag vulcanized ah, bacaha iyo warshadaha kale, iyo horumarinta iyo design suuqa rajada waa mid aad u ballaaran.
