Polyisobutylene CAS 9003-27-4
Polyisobutylene (PIB, CAS 9003-27-4) waa polymer toosan oo buuxa oo laga helo polymerization cationic ee isobutylene monomer. Ma aha sun, ur la'aan, aad u deggan, aad u hawo-celin badan, aad u dahaaran, qaabkeeduna wuxuu ka beddelaa dareere fiiqan → nus-adag → elastomer caag ah marka miisaanka molecular-ku uu kordho.
Aad u adkaysi u leh gabowga iyo xasilloonida kiimikada
Buuxnaanta silsiladda oo buuxda: u adkaysta kulaylka, ogsijiinta, ozone-ka, shucaaca ultraviolet-ka, asiidhyada, alkalis iyo cusbada, ma burburaan ama ma noqdaan kuwo jajaban muddo dheer
Xasiloonida kulaylka: waxaa loo isticmaali karaa muddo dheer -50℃ ilaa 150℃, iyadoo leh dhibic iftiin sare leh iyo gubasho yar
Cidhiidhi sare + dahaadh sare + awood-u-qaadis hoose
Cidhiidhi aad u xoog badan: sifooyin caqabadeed oo aad u fiican oo ka dhan ah biyaha, gaaska iyo uumiga, oo aad uga sarreeya caagga caadiga ah
Dahaarka korantada oo wanaagsan: iska caabin mug sare leh, lumis dielectric oo hooseeya, oo ku habboon fiilooyinka/shaabaynta korantada
Ammaan ah oo aan sun ahayn + iswaafajin ballaaran
Heerka cuntada ee FDA: aan sun ahayn, aan xanaaqin, waxaa loo isticmaali karaa xanjo, qurxinta, iyo waxyaabaha kaabayaasha daawada
Kala go'an oo leh hydrocarbons/caag/resin: si fudud ayaa loo isku dari karaa loona beddeli karaa, iyadoo la hagaajinayo isku-dhafka, dabacsanaanta iyo iska caabbinta cimilada.

2) Miisaanka molecular-ka ee dhexdhexaadka ah (Mw 10,000 - 100,000, caag nus-adag / jilicsan)
Wax ka beddelka caagga: balaastikada caagga ah ee acrylonitrile / chloroprene, oo xoojinaysa iska caabbinta saliidda iyo adkaanta hawada
Fiilooyinka / fiilooyinka: dahaarka dahaarka, galka biyuhu aanay biyuhu gelin, dahaarka u adkaysta cimilada
Dahaadhka / laastiigga: dahaarka ka hortagga daxalka, wax ka beddelka laastiigga (ka hortagga dildilaaca, ka hortagga gabowga)
3) Miisaanka molecular-ka oo sarreeya (Mw > 100,000, elastomer-ka u eg caag)
Cinjir gaar ah: taayir gudaha ah oo hawo adag leh, qayb shaabad faaruq ah, gaaska ka hortagga gabowga
Wax ka beddelka balaastikada: Xoojinta PP/PE, xoojinta iska caabbinta saameynta iyo iska caabbinta cimilada
